Abstract
The utility model discloses a connecting rod valve which comprises a valve body, a valve cover, a valve rod and a spherical valve core. The valve core and the valve body are detachably installed, an installation hole where the valve rod is arranged is formed above the valve body, a valve cavity where the valve core is arranged is formed under the valve body, the valve rod penetrates through the installation hole and penetrates through the valve core to be fixed at the bottom of the valve body, an O-shaped sealing ring is arranged at the connection position between the valve rod and the valve core, the top and the bottom of the valve core are in nut fastening connection with the valve rod, and an O-shaped sealing ring is arranged between the valve rod and the installation hole. The connecting rod valve has the advantages of being high in stability, good in sealing performance and excellent in corrosion resistance.
Description
Technical field
The utility model relates to valve, is specially a kind of linkage rod type valve.
Background technique
In industrial or civilian infrastructure, conventionally utilize Pipeline transport medium, wherein due to the variation of pressure or temperature, to regulate pipeline, for adjust flux is used regulation structure one valve in pipeline, to guarantee best operating conditions and the safety of environment.
In existing valve technology, its valve rod is generally fixed on spool top, and when being subject to medium fluid impact, valve inner can produce vibration, the joint of valve rod and spool can be loosening because of vibration and fluid impact generation repeatedly, thereby affect stability and the seal of valve rod and spool.
Model utility content
The purpose of this utility model is the problem of mentioning in above-mentioned background technology in order to solve, and provides that a kind of stability is strong, good leak tightness, the good linkage rod type valve of wear resistance.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of linkage rod type valve, comprise valve body, valve gap, valve rod and spherical spool, described valve gap and described valve body are detachably installed, described valve body top is provided with the mounting hole of installing for described valve rod, below is provided with the valve pocket of installing for described spool, described valve rod is through described mounting hole, and running through described spool, to put described valve body bottom fixing, on the joint of described valve rod and described spool, be provided with an O seal ring, the top of described spool and bottom are all fastenedly connected with described Stem Mut, between described valve rod and described mounting hole, be also provided with an O RunddichtringO.
Further, described mounting hole bottom offers first ring recess that described O RunddichtringO is installed, and corresponding described the first ring recess position, offers the second ring recess on described valve rod.
Further, described spool periphery is provided with one deck anticorrosion antiwear alloy-layer.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the stability of the utility model valve rod and spool is strong, good leak tightness.The linkage rod type valve that the utility model provides on the basis of existing technology, valve rod is passed to mounting hole, and running through spool, to put valve body bottom fixing, on the joint of its valve rod and spool, be provided with O RunddichtringO, its spool top and bottom are all fastenedly connected with described Stem Mut, make when medium fluid is passed through spool, impact energy between its valve rod and spool accesses buffering, thereby improved the stability of valve rod and spool, in addition, the O RunddichtringO that its valve rod and spool joint arrange, strengthen the seal between spool and valve rod, preventing that the joint gap of medium fluid by spool and valve rod from spilling in valve body causes corrosion failure to valve.
2, between the utility model valve rod and mounting hole, be provided with O RunddichtringO, this O RunddichtringO is good leak tightness not only, also has surface friction drag little, the feature that wear resistance is good, thereby this is arranged on when improving valve self seal, also reduced valve torque power, valve rod is rotated more for convenience.
