What is a pairs of dowel joint flange？

The detachable joint depends on the reciprocating piston (or plunger) in the detachable joint cylinder to change the volume of the detachable joint cylinder, with the action of two check valves, to achieve the purpose of suction or discharge of liquid. According to the structure of the piston, it can be divided into three kinds: piston detachable joint, plug detachable joint and diaphragm detachable joint. The main component of the piston detachable joint is the piston, relying on the piston to work in the removable joint cylinder, inhaling or excreted liquid. The main part of the plunger detachable joint is the plunger (cylindrical), which is larger than the piston contact area and wear-resistant. The detachable joint acts in exactly the same way as the piston.

Advantages of the pairs of dowel joint flange：
1.Good sealing performance
Butterfly valve with detachable joint, disc and valve body rubber sleeve clearance match, not only to ensure sealing, but also to ensure that not stuck.
2.Stable performance
The design stress of detachable joint requires to reduce the closing force and closing torque, and the movement is sensitive and reliable, the operation is flexible, and the opening and closing speed is stable.
3.Wear resistance
The main component of the plunger detachable joint is the plunger (cylindrical), which has a larger contact area than the piston and is more resistant to wear.
4.Suitable for different media
Various specifications of rubber soft joints can be manufactured according to different user requirements. Using advanced technology can be made into various specifications and performance between the expansion joint. At the same time, it is also suitable for various medium conditions between 0 and 80 degrees, and can withstand various chemical corrosion and thermal expansion and contraction, and can work normally under various high temperature conditions and various low temperature conditions.
