Description

A kind of valve

Technical field

The utility model relates to valve body technical fields, and in particular to a kind of valve.

Background technique

Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting Or the functions such as overflow pressure relief.

Traditional valve is by the on-off of rotary spool control valve both ends pipeline, and wherein rotary course needs benefit It is formed and is sealed with the extruding between spool and valve chamber, the extruding which not simply reclines, but generate in friction process, Abrasion will necessarily be generated after friction use for a long time, once the pressure squeezed is unable to reach pre-provisioning request, under leakproofness will be serious Drop.

Utility model content

For the defects in the prior art, the utility model provides a kind of valve, realizes and avoids traditional valve body control The abrasion that the process of on-off generates, service life is more lasting, the more stable technical effect of sealing effect.

In order to achieve the above objectives, a kind of valve provided by the utility model, including valve chamber and spool；One end of the valve chamber Equipped with the first valve port, the other end of the valve chamber is equipped with reciprocating mechanism, the side wall of the valve chamber be additionally provided at least one second Valve port；The spool includes drive rod and the plug that is adapted to first valve port, and one end of the drive rod is fixed described stifled Head, the other end of the drive rod are connect with the reciprocating mechanism, which passes through described in drive rod drive First valve port is blocked or is opened by plug.

The technical principle of this programme is as follows:

This programme is used to control the on-off between the first valve port and the second valve port；

It drives drive rod to move back and forth by reciprocating mechanism, and then realizes the replacement of two states, plug is made to recline Perhaps the first valve port is blocked or opened to control plug far from the first valve port.

The technical effect of this programme is as follows:

This programme passes through the on-off of reciprocating drive mechanism application valve body, and the process for avoiding traditional valve body control on-off generates Abrasion, service life is more lasting, and sealing effect is more stable, better tightness, can also even if plug has small abrasion To overcome by adjusting reciprocal amount of feeding realization.
