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?
- Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.
- Q: Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
- Switching type (one on and off)Block digital display with the upper and lower limit control valve opening and closing is goodProbably more than 100Regulating type (to keep temperature at a constant value)With PID valve position regulator can be very good controlAbout 300 more
- Q: How to find all kinds of mysterious valves of human body?
- Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.
- Q: How about the quality of FITOK valves?
- Purely under the banner of what import, in fact, everyone knows, is the genuine domestic goods.
- Q: The valve is rusty and can not be opened. What shall I do?
- There are pictures, for different valves, then choose different ways of opening.
- Q: How to check if the gas valve is open?
- Method 1: gas valve has a handle, the handle is parallel to the pipe, that is open, vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the handle is parallel to the pipe, that is, the open state, vertical is closed.Method two: the valve handle and pipe to "one" word proved to come, into "ten" word is off. Also, turn the handle clockwise and turn counterclockwise.
- Q: What is the purpose of the valve?
- 6. Indicate and adjust the level of the liquid. Such as liquid level indicator, liquid level regulator, etc..7, other special uses. Such as temperature control valve, over-current protection, emergency shut-off valve and so on. In the above valves, the valve used to connect and cut off the medium flow in the pipeline, the use of the total number of about 80% of the total number of valves.
