Q:Are the gate valves and check valves of the same type?
Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.
Q:Check valve h42h-dn80 what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm
Q:Standard and specification for stop check valves
Design and manufacture: GB12235 structure length: GB12221Pressure temperature range: GB9131, JB/T74, HG20604Connection flange: JB/T79, GB9113, HG20592Test and test: JB/T9092, GB13927
Q:What does the swing check valve "h44h-16" mean?
Swing check valve with the built-in rocker swing structure, all opening and closing parts are arranged in the valve body of the valve, the valve does not penetrate, in addition to the seal gasket and seal ring with flange, overall no leak, to prevent leakage of the valve may be. Swing check valve rocker and disc connections using spherical connection structure, so that the valve in the 360 degrees within a certain degree of freedom, there is appropriate micro position compensation.
Q:What is the function of the ventilator's check valve?
When the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.
Q:Which type of check valve should be selected for vertical pipes?
The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited
Q:Use of fire pump adapter even before you install a check valve
Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.
Q:Installation position of household water meter check valve
Generally installed after the water meter.The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter.A check valve is installed after the water meter, so that the situation can be avoided.
Q:Does the Vatti range hood e601a2z have check valves?
Vatti range hood e601a2z check valve, smoke machines must be equipped with check valve.Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.
Q:Is the check valve in or behind the gate valve? Why?
Check valve in the valve in front. To prevent water from flowing back.
