Pinch valve, also known as pressure valve,is a valve that uses manual, pneumatic, electric and other driving methods to squeeze the internal rubber tube to On-off or regulate the flow. Pich valve is composed of upper and lower valve body, rubber sleeve, Upper and lower stem, upper and lower gate, left and right guide post and other parts; As the core component, the rubber sleeve is usually composed of an inner layer, an outer layer and a reinforcing fiber, and is formed by vulcanized rubber. Common rubber sleeve materials are natural rubber, fluorine rubber, neoprene rubber ball, EPDM rubber, nitrile rubber, food grade rubber ball and so on. When the hand wheel is rotated clockwise, the size of the pinch valve stem simultaneously drives the upper and lower valve plates to compress the rubber sleeve, and the valve is closed. When it is turned anti-clockwise, the valve is opened due to the joint action of the elasticity of the rubber sleeve and the pressure of the medium. The gate moves up and down between the left and right guide to complete the valve opening and closing; During the closing, Once it feels the connection between upper and lower sleeve, then stop continuing to close, More torque will damage the sleeve. The Pinch valve can be installed in any direction on the pipe, and there is no medium flow limit. After using for a long time, if the rubber sleeve is found to be worn and leak happens, just disassemble the upper and lower valve body and replace it with a new rubber sleeve. The valve body can be reused and the maintenance cost is very low.

Hannelore came from Demag hydraulic company in Germany and started to work in Shanghai branch at the beginning of the previous year. I don't have much contact with the Shanghai office. Frankly speaking, I'm not very good at dealing with these offices with Chinese people. These people are unprofessional and backseat drivers, they also need kickbacks. I hate kickbacks in business. In August last year, Hannelore asked whether AAK was willing to cooperate with them to develop a high-precision hydraulic pressure control valve, and attached the drawings and working condition requirements. After several rounds of email communication, I learned that they were in big trouble with this hydraulic pressure control valve, which made him irritable. They have a hydraulic injection molding machine to be promoted at the exhibition in October. This high-precision hydraulic injection molding machine has very high requirements for the accuracy of its core components. The accuracy requirements for the hydraulic pressure control valve used have been strictly refined in 4 aspects. The boss asked Hannelore to find a manufacturer of hydraulic pressure control valves with high quality. After a round of inquiry, only two factories were willing to try samples, and the others said that the accuracy requirement was unbearable. Two months later, the samples from the two hydraulic pressure control valve manufacturers were tested. Unfortunately, there was still a deviation in the accuracy, but both manufacturer was unwilling to try again. In other words, his busy more than two months were in vain, and the boss was already very unhappy. After analyzing the drawing of the hydraulic pressure control valve, AAK engineers found that the 4 accuracy requirements are more than twice that of the standard hydraulic pressure control valves. At the same time, the diameter of the blind hole in the valve body is only 5mm, but the depth needs to be 50mm long, it is very thin and extremely deep. During the processing process, the tool cannot pass through the hole completely, and the inner hole is easy to cause radial deformation, and the axial taper requirement is 1:45, and the ovality cannot be greater than 0.01mm, this accuracy is too difficult to control. No wonder all of those manufacturers have surrendered. After 3 days of study and research, AAK technical team informed that the samples of hydraulic pressure control valve could be sent after 40 days. Hannelore emailed me the bank slip of the development fee the next day, and stressed that AAK must find a way to deal with it, otherwise he was very afraid of the boss's outbreak. Two weeks after the sample was sent, his email came. AAK hydraulic pressure control valve passed the accuracy test, and the test result on the machine was good. Their team was confident that it would sell well at the exhibition. After the exhibition ended in October, Hannelore placed the order for 1,000 hydraulic pressure control valves. Hannelore privately informed that the equipment had sold well, and the boss's cold look at him turned into a happy face. After 4 months of anxiety, he could finally relax. The reason why we did what our peers all surrendered is that there are 3 points: 1. The production process of hydraulic pressure control valve is set up with ingenious tricks, including drilling, reaming, coarse reaming, fine reaming, hole cutting, and calibration, changing the speed, adjusting the accuracy coefficient, eliminating the bell mouth of blind hole and strictly control the surface roughness. 2.Use the Swiss high-precision machine tool and the bladed reamer to cut the hole, and the roughness of the blind hole reaches Ra value of 0.2-0.4 μm. The ovality circle error is 0.01-0.02mm, the taper error is 0.01-0.025mm, and the dimensional accuracy of the hole can be controlled within 1μm. 3.Before machining, the accuracy of each axis of the machine tool is tested, including positioning accuracy, repeated positioning accuracy and reverse positioning accuracy. After obtaining the test data, the accuracy is compensated. Most hydraulic valve manufacturers ignore this small detail. AAK hydraulic pressure control valve, benchmarking the accuracy of international first-line brands, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-control-valves- aak281

I am a Chinese solenoid cartridge valve manufacturer, and have spent all my time of 30 years on solenoid valves. Although I have only made a small profit, I have read many books and always understand a truth: where is time spent, achievement lies. Yesterday, an old friend asked us to go to his house for lunch, and help him guard a pass for his future son-in-law by the way. This friend believes that I read a lot and see people accurately, so he invited me to this lunch. Pitiful world parents heart, which is also a characteristic of China. After dinner, we chatted casually, then the boy left, for the boy's company was temporarily busy and he had to work overtime. I said to my friend’s daughter, 'Is there any future development for your boyfriend or the man you're going to marry?'? Actually, it can be seen from 2 points: 1.Where did he spend all his time? 2.What are the friends he makes? If his social circle showcases life and leisure activities, such as traveling today, going to the gym tomorrow, and having a friend gathering the day after tomorrow, then skiing, diving, red wine, coffee... even if he is driving a luxury car and wearing a brand name, he will not have much success in the future. Because these are not his own, perhaps he has a good family. How can a serious man under 45 waste his time on these? All their time is spent on making money. I remember that in the first 5 years after starting my business, I had no rest for the whole year. It is not easy for a China solenoid valve manufacturer to become famous. I not only focus on the quality of solenoid valve manufacturing and optimize the structure of solenoid valves, but also make some local innovation of solenoid valves, all of which require time and skills. And what kind of friends does he make? If those friends are not as good as him, or are all similar to him, he will be like this in his life! Birds of a feather flock together. He hasn't even made an awesome friend, so he won't be able to awesome in his lifetime! Girls in love must pay attention to advice from family relationships, because only family relationships are the eternal rocks by the sea, and love is like the rising and falling tides of the sea. No parents will harm their children, and children will not truly understand their parents' pains until they become parents. Modern parents don't have anyone who wants to get something from their children's marriage, just to give you a check. Who is more trustworthy, your mother or your man? Of course it's your mother, she won't lie to you! Of course, heavy industry is a unique feature of China. What kind of friends do you make around you? This can also be compared to China solenoid cartridge valve manufacturer. What customers do you serve? If these customers have low quality requirements, as long as the price is cheap, the manufacturing quality is certainly just fine. If a Chinese solenoid valve manufacturer does not have even one awesome customer, then it is not possible for this manufacturer to be awesome. AAK solenoid valve, 2-24-72 hour service, for awesome customers AAK HYDRAULIC VALVES (568) 2023-04-23 https://www.aakindustry.com/info , -detail/solenoid-valves-aak568
