Q:What are the differences between different check valves applications?
Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
Q:What type of check valve should be installed before the suction pump?
Self priming pumps are equipped with rotary, rotary or automatic type check valves.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. Forged steel check valves two body cover to connect the design form: the first is the body cover bolt connection forged steel valve, connected by this form of valve, the valve body and the valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance;
Q:Which kind of steam check valve is good?
Steam check valve selection spring pressure check valve is better, can be sealed tight.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. 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:Where can I find the good check valve?
If the soft seal check valve, or buy Tianjin Hengyuan valve, good quality, moderate price, have the shelf life.
Q:I also calculate each pump check valve and gate valve?
Are you talking about budget calculations? According to the bill of quantities valuation standard, the project code 030701019 has included what you said, without additional calculation.
Q:What is the difference between the check valve and the check valve?
Check valves, Dan Xiangfa, check valves are all valves of a different name, and its role is to prevent the flow of fluid back in the pipe.
Q:What type of check valve is the h61y-40 check valve?
Two, swing check valve: the valve swing check valve cylindrical disk-shaped, around the seat of the shaft for rotation channel, because the valve channel into a streamlined, flow resistance than the small valve lift check, suitable for large caliber occasions in low flow and no flow frequently change, but not for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact. Three, compression type check valve: This valve is used as boiler water supply and steam cutting valve, it has lift check valve and stop valve or angle valve comprehensive function. In addition, there are - some do not apply to pump outlet check valve is installed, such as valve, spring-loaded check valve, Y type check valve check valve. Four disc check valve: disc check valve around the pin rotation in the valve seat.
Q:How much is the 6 point check valve for the water pipe at home?
1, home hose with 6 points of the water pipe, check valve, copper 20-40 yuan.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, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
Q:The working principle and structure description of the mute check valve
When the valve is in use, the medium flows according to the direction of the arrow.1, when the medium according to the provisions of the direction of flow, the valve by the media force, is open; the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.2, the body and valve sealing surface using stainless steel surfacing.3, the length of the valve according to the provisions of GB12221-1989, flange connection size according to the provisions of JB/T79-1994.
Q:Is there a check valve with a relief valve above?
Over the excess pressure discharge, maintain protection of pipeline system valve. For reference!
