300 x slow-closure valve by the main valve, check valve, needle valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Using hydraulic automatic operation, can make the main valve to get the best opening or closing speed. Prevent the formation of zhong water water hammer, in order to achieve slowly-closing silencing effect. 300 x slow close check valve with hydraulic control on our own efforts, do not need other devices and energy, maintenance is simple, open and slowly-closing smoothly.
300 x slow close check valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering.
When the valve from the inlet water supply, water through the micro filter, needle valve, check valve into the main valve control room, through the ball valve and drainage to the downstream. Because the needle valve opening is less than the ball valve opening, the main valve control room is greater than the water drainage speed, so the control pressure is reduced, on the main valve inlet pressure of the bottom of open the main valve to supply water to the water downstream.
When pipe to stop water supply, if the downstream water flowing back, part of the return water enters the main control room, the ball valve with one-way valve, the reflux water cannot flow from the main control room, cause the main control room pressure rise gradually, slowly closing the main valve.
- Q: Is the valve clockwise?
- The valve clockwise rotation of the handwheel is to close the valve, counter clockwise direction is to open the valve, the number above said valve opening rotating the handwheel clockwise along the colonel, to the above number 0 corresponding pointer is completely closed; in counter clockwise direction, to a maximum of 5 numbers above corresponding pointer, is the valve open to the largest degree.
- Q: Where is the hydrant main valve?
- The fire hydrant generally has two sources, one is from the roof water tank, a water pump is from the housing, maintenance, should close the fire hydrant located on the riser inlet valve tube under the ring, generally located in the top and bottom, and then discharge, when the valve cannot be closed, the proposed closure of replenishment valve and the pressure stabilizing device of water tank, fire pump in manual state, drainage after maintenance. Watch out for fire.
- Q: Ketem valve relative to other valve companies in the industry what are the advantages?
- Floating hard sealing electric ball valve is suitable for two cutting and adjusting occasions. Connect the valve and actuator by using direct connection, DCL series miniature electric actuator (also can be configured according to user requirements of the electric actuator or pneumatic piston actuator of different types of electronic components and ultra short ball).
- Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
- Pneumatic valve compared to the electric valve, the valve can be the same, rubber lined butterfly valve or other valves, pneumatic valve opening speed (Basic 1 second can be fully open), the price is lower than the electric valve. But there must be process air (4-6bar compressed air). According to my experience, if the scene has compressed air, it is recommended to use pneumatic valve, if there is no compressed air, it is recommended to use electric (electric valve expensive, open valve slow).
- Q: What do O and S mean on the valve?
- Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state
- Q: What valve is the VENT?
- VENT generally use a check valve (resembling a screw, spring preload), also directly using the plugA two-way sealing type ball valve for example, in order to detect the leakage of the pressure after the end, also for pressing the cavity is convenient, usually in the body cavity external to the up position to open a checking leak, which is VENT.
- Q: What is the flow medium of the valve?
- What is the valve. If the water through the valve, the medium is water. I hope I can help you.
- Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
- On the valve network to find the best, you can find the valve business in Anhui
- Q: someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- You should live in a high-rise, if there is no power failure, that is, the water tank pump failure, and urge property repair is.I hope I can help you
- Q: Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
- The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
