- Q:What is the function of the check valve?
- 1. Check valve function: prevent backflow of medium, prevent pump and drive motor reverse, and discharge of container medium.2, check valve refers to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve.3, check valve according to the structure of the division, can be divided into lift check valve, swing check valve and butterfly check valve three:Lift check valve is divided into two types of vertical and horizontal.Swing check valve is divided into single, double valve and multi flap type of three.Butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.4, check valve (Check, Valve) installation should pay attention to the following mattersA do not allow the check valve to bear weight in the line, and the large check valve shall be independently supported so as not to be affected by the pressure generated by the piping system.B, when installing, pay attention to the direction of the flow of medium should be in accordance with the direction of the body marked arrow.C and vertical vertical check valves shall be installed on the vertical pipe.D and lift type horizontal check valves shall be installed on horizontal pipes.
- Q:Butterfly micro stop type check valve HH46XP-10Q, what does the letter mean?
- The first H stands for slow closing, the second H represents the check valve, the X represents the sealing surface, and the rubber, the P represents the butterfly plate, and the stainless steel Q represents the ductile iron.
- Q:The difference between check valve and check valve
- The same thing, called, is based on the difference in the use of the actionFor example, overflow valve and safety valve, back pressure valve, are the same thing, are in the one-way valve behind the increase of back pressure spring
- Q:What is the function of the ventilator's check valve?
- The flue check valve refers to the automatic opening and closing valve plate, which is used to prevent the backflow of soot through the thermal flow of the range hood. It is also called the smoke back valve, the smoke prevention treasure and the flue isolator.
- Q:What's the difference between a throttle valve and a check valve? Are they the same?
- The principle is very simple, just like upstairs said, like a revolving door, this is the swing test. There are lifting type, it is unknown.And "throttling" is to reduce the pressure of the fluid. In the pipeline, the fluid through the throttle valve, through the hand wheel or other transmission way to adjust the size of the internal channel, so that the flow of fluid flow down, to save traffic flow.
- Q:Can the check valves fit two in one tube? One up, the other down
- A water pipe is used for launching, and the two check valves that you install are reverse, and the water is blocked by one of the check valves on either side
- Q:Why is the water ring vacuum pump equipped with check valves?
- The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
- Q:My hood inside outside blow valve pops ringing
- The hood check valve is in two halves of plastic. It is too light and the wind vibrates. You can add some things, as long as the soot blowing function is OK (try several times). Able to solve problems.
- 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:Should the kitchen check be mounted on the wall or on the hood?
- Buy their own check valve is generally in the wall of the hole, the hood of the smoke machine, usually with a check valve.
