Connection between valve and pipeline or equipment choice is correct, right will directly affect the pipeline valve run, run, drip, leak phenomenon. The common valve connections include: flange connection, connected to the clamp, butt welding, threaded connections, card sets of connection, the clamp connection, since the sealing connection, and other forms of connection.

Constant pressure water supply equipment in the valve flange connection:
With flanges on both ends of the valve body, and pipe flange on the correspondence, by bolted flange is installed in the pipeline. Flange connection is a connection form of valve used most frequently. Flange with sudden surface (RF), plane (FF), the concavo-convex surface (MF), etc. According to the joint surface shape can be divided into the following kinds:
1, smooth type: used for low pressure valves, processing more convenient.
2, the concave and convex type: high work pressure, can be used in the washer.
3, mortise type: plastic deformation is larger washers are available, and in the corrosive medium is used more widely, the sealing effect is better.
4, trapezoidal groove: with oval metal ring gasket, used to the work pressure of 64 kg/cm2 or valves, valve or high temperature.
5, lens type: the washer is lens shape, made of metal. For a working pressure of 100 kg/cm2 or high pressure valve, or high temperature valve.
6, the o-ring type: this is a relatively new form of flange connection, it is with the emergence of a variety of rubber o-ring, and developed, it than ordinary flat washer on the sealing effect is reliable.
In the constant pressure water supply equipment connected to the clamp of the valve
Valve installed in the middle of the two pieces of the flange, the body usually have positioning hole to facilitate installation location, bolted directly to the valve and the connection forms of two pipe clamp wear together.
Welding connection
1, the butt welding: according to the requirements of butt welding process on both ends of the valve body into the butt welding groove, and pipe welding groove, fixed by welding on the pipe.
2, socket connection: according to the requirements of socket welding processing on both ends of the valve body, and pipeline through the socket connection.
