Q:What is the function of the small check valve on the deep well pump?
This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
Q:Can the check valve be horizontally installed?
Sure. As long as the direction of the check valve is installed, it's no problem how to install itWe can sell this, I know the user name is my phone, you go to the Advisory bar ~!
Q:How to install fire fighting pipe and flue fire check valve?
7, the flue is thin-walled components, in handling and installation should be gently handle, not to impact, not in the pipeline to pile other heavy objects and walking.8, the roof flue should be in the roof insulation layer, fire layer before construction.9, the use of gas water heater exhaust system is strictly prohibited.
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:How to control the common flue return and smoke return?
In the hood outlet to install a reasonable design, shut tight, open the hood in place, can be easily wind blown open, will not be open to the flue suction, and the blade contact area is very small, and a sealing ring, not to hinder the blade opening exhaust flue check valve closed Miller beauty you can eliminate the smoke intrusion and poor smoke.
Q:What does the check valve "H41F" mean?
According to the provisions of the JB/T 308-2004 valve type programming method:H== check valve4== connection: flange type1== structure form: lifting typeF== sealing surface material: fluorine plastic
Q:What is the HC41X-16Q model of the optical valve? What is its main function?
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. Not suitable for medium containing solid particles and viscosity. When the medium according to the provisions of the direction of flow, the valve by the media force, is open;
Q:To prevent water meter rotation, where should the check valve be installed?
Place it at the top of the water meter, as you can see, near the valve
Q:Does the Vatti range hood e601a2z have check valves?

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:How to prevent the backflow valve of medium
Check valve operating principleCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, 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 check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).
