Q:Are check and check valves the same kind of thing?
The same thing is not the same as it is
Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?
The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly valve for the straight through, the above non-return valve can be divided into connection, flange and welding of three lift check valve and stop valve structure similar to the thread in the form of connection, the valve in a line along the channel for the lifting movement, reliable action, but the fluid resistance is large. Small in diameter for the occasion. Lift check valve can be divided into straight and vertical two kinds. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe. You can see the picture in Baidu's picture
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:Install check valve is not afraid of water, in case the back of the water pollution?
The check valve is to prevent the backflow of water from the pipe after the pump stops. If the pipe is very large and the water is flowing back every time, isn't it a waste?If the water tank or tank pipe at the bottom of the pool, it must check valve, or a box of water will drain off, if the line is not big, the water inflow of the water is from the top of the box, it can also be installed check valve. Is not loaded with pipeline and process!
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:How to prevent the backflow valve of medium
The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite 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.
Q:What is the difference between check and check valves? Check and check valves?
3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar
Q:How to install the water pipe check valve?
If the pipe in the installation position is vertical, you can choose the swing type and pipe type!If the installation position of the pipe is horizontal, you can choose the lifting type!Lift check valve opens and stops at the fastest speed!The swing check valve has the least resistance!
Q:Back pressure valve and check valve difference
Oil is generally put into the wells of the check valve calling back pressure valveCheck valve is a general name, mainly lifting type and swing type.
Q:Is the overcurrent valve a check valve?
The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
