Q:There is a check valve at the inlet of Haier electric water heater to prevent water from flowing back. Because there are many hot water used in the house, should the hot water be fitted with check valve?Can the hot water outlet be fitted with check valves? The hot water pipe is too long for hot water to flow back into the heater... Is it possible to install two check valves to affect the normal use of the heater?
Hot water outlet should be equipped with check valve, for the following reasons:Closed type electric water heater in the outlet by one or more water control valves and water storage type electric water heater, and work in tap water under pressure. The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe.
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:Is there a check valve with a relief valve above?
You can be sure to answer, no such installationThe fire check valve is not the same as the relief valve.
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:The difference between slow closed valve and open the valve
The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).
Q:Does the regulator have a check action? If yes, can I use it as a check valve?
There are some regulators that have this reverse cut-off. A regulator without overflow. Such as gas regulator.For example, the compressed air regulator has no reverse cut-off function.Regulators in the form of a lot of specific circumstances, specific analysis, only to exceed the body can withstand the pressure, generally not bad.
Q:How can the check valve be distinguished from the cut-off valve?
1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed. 7, Y%, s) C, N, L., Q3, U6, J&, E9, R2., the cut-off valve can be used to regulate flow, can be closed, can be closed.
Q:Installation position of air pipe check valve
If you are not in a hurry, leaving QQ, etc. I reply to your husband for this afternoon, he is very professional.
Q:Install check valve is not afraid of water, in case the back of the water pollution?
The function of the check valve is to prevent water from flowing back. It is mainly installed at the outlet of the water pump to protect the water pump from reversing, so as to avoid the pump damage and mechanical accident.Usually between the water pump outlet pipe and the water tank inlet, must be equipped with check valve, to prevent water backflow!
Q:What's the difference between a stop valve and a check valve? Is it a valve?
A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards. The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface.
