Q:How do I use the triangle and check valves?
The triangle valve is used for connecting taps and water equipment. Check valves are used to prevent backflow of water.
Q:Is the hdf41x 1.6Mpa a check valve?
Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution.
Q:What's the difference between the check valve and the stop valve?
The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
Q:What about boiler non-return valve without return?
Reliably disconnect the front and rear valves of the check valve and open the check valve spool. 1, lift check valve, remove dirt and impurities out of the valve, and the necessary lifting shaft between the sand, and then check the sealing surface (line), install the recovery; 2, open the valve, visible to the rotary valve plate, sometimes is the axis of rotation is not flexible, it will add oil activities for many times, then look at the rotary valve in the fully open, whether the opening angle is too large, can not rely on medium reflux and gravity recovery closed, if so, then the opening plus limit (which can be in the spool in the valve plate drilling and tapping screw, in a small Luo Si), do not let the valve plate open to the vertical state, which can be opened to an angle of 80 degrees. You can have a try. Good luck. Happy new year.
Q:What is the difference between the silent check valve and the silent check valve?
It can be installed horizontally or vertically. The valve is loaded by spring, and its quick closing can effectively eliminate the water hammer. It has good sealing performance and no noise.
Q:What is the material of H41W-16's check valve?
According to: JB/T 308-2004 "valve type programming method"H check valve4 flange connection1 lift through straight through valve passageW sealing cover for body material16 nominal pressure PN16When the nominal pressure is less than or equal to PN16, do not mark the material code of the valve body, the valve body material is gray iron
Q:What's the difference between the h76x check valve h77x?
Check JB/T308-2004 "valve type programming method"The first number 7 is the clip typeThe 6 is a double valve swing structure7 butterfly check valveLook at the JB/T8937-2010 "clip on check valve"That's clear
Q:How many kinds of structure are there in the check valve?
2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
Q:The difference between backflow preventer and check valve
Plain and simpleBackflow preventer is double acting, better than check valve
Q:PPR check valve, butterfly valve, as well as water gauge which quota?
The valves and water meters installed in the same pipe are the same
