But there is still a little gas, corrosive gases such as ammonia, the demand for lower pressure valve. ( 5) Reduce the pressure valve should prevent the impact of oscillation, can not contact with corrosive thing. Plunger valve, turn the adjusting screw, change the height of the valve to open, so to adjust out high body over limit and achieve the required pressure value. Supreme inlet pressure mostly, the minimum inlet pressure not less than 2 of outlet pressure. 5 times. Because of this, when in use, should maintain the two hemispheres of the surface is bright and clean, rotor pump to ensure satisfactory airtight effect. It is to try to take care of reduced pressure valve and make the safe use of devices, and reduce the pressure valve revealed the fault signal device. ( 3) Oxygen gas reduced pressure valve should be banned from contact with grease, lest send to ignite fuel police accident. ( 4) When resting office, should put a net the lower residual air in the pressure valve, and then loosen adjusting screw so that permanent compression elastic element variant. Reduced pressure valve and cylinder think appropriate and use the surface of the hemisphere petition, by tightening the screw nut to make both the absolute. However, should also be pointed out that: dedicated to reduce pressure valve normal in other gases. Reduce the pressure valve is equipped with safety relief valve. The low pressure table outlet pressure can be adjusted by the screw stem. 3. Other principle of reducing pressure valve a little gas, such as nitrogen, air, argon gas for a long time, can see fit and use oxygen gas reduced pressure valve. 2. The use of oxygen gas reduced pressure valve ( 1) According to the requirements of use, oxygen gas reduced pressure valve has many specifications. Such as hydrogen and propane are right and use the left tooth turnbuckle, also known as reverse turnbuckle, when installation should be believing. Using the first open the cylinder when the master switch, and then clockwise (low pressure gauge pressure adjustment screw, the compress the main spring and transmission film, spring block and the plunger and valve open. The use of the lower pressure valve way and pay attention to the things of project with oxygen gas reduced pressure valve is basically the same. ( 2) Installing a lower pressure valve should confirm whether the petition specifications with the joint of the operation system of the cylinder and exactly the same. High pressure table of value for the pressure of the gas storage in the cylinder. 。 Outlet pressure and specifications, common for, the outlet pressure of the Buddha. In order to avoid misuse, a bit of a special reduced pressure valve with right between the cylinder and use special signatures. Have in common market nitrogen, air, hydrogen, ammonia, acetylene, propane, water vapour and other special Marine valve to reduce pressure valve. Out so imported high-pressure body by high pressure chamber after throttling pressure lowered into the low pressure chamber, and the export to the office. Also available when the indispensable materials such as ptfe gasket. Q: low temperature to reduce the pressure valve principle and using way of answer: 1. Oxygen gas reduced pressure Industrial Valves office principle of oxygen gas reduced pressure valve of high pressure chamber and the cylinder petition, low pressure chamber for gas exports, and to use the system. Hi-pressure dying body blow the dust before installation. If because the valve gasket, valve damage, or because other comprised, pressure to rise and exports more than a certain value, the safety valve will be semi-automatic open exhaust, more is to reduce the pressure valve principle. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
