Abstract
The invention relates to a novel valve core connecting sleeve mechanism for a stop valve. The valve core connecting sleeve mechanism is provided with a valve body, a connecting cavity is arranged in the middle position of the valve body and is connected with an oil outlet, a valve seat is connected on the same axial line of the valve body and the connecting cavity, a through hole is arranged on the valve seat, the right end part of the through hole is provided with a conical hole, an O-shaped sealing ring is arranged at the inner side of the conical hole, a valve core is connected onto the opposite surface of the valve seat, a cone head is connected with the left end part of the left valve core, the conicity of the cone head is the same as the conicity of the conical hole of the right end part of the valve seat, screw threads are connected with the right end of the valve core, the valve core connecting sleeve is arranged at the right end part of the valve body through screw threads, and a sealing ring is arranged at a connecting part among the valve body, the valve core and the valve core connecting sleeve.
Description
Technical field
The present invention relates to a kind of spool connecting sleeve mechanism, particularly a kind of novel cutoff valve spool connecting sleeve mechanism belongs to technical field of hydraulic elements.
Background technique
Stop valve spool connecting sleeve mechanism is a hydraulic element cover commonly used in the hydraulic system; At present, though stop valve spool connecting sleeve mechanism is various in style, size is not quite similar; But; Because the complex structure of stop valve spool connecting sleeve mechanism is so ubiquity difficult defective of closing dead, easy leakage, installation and maintenance inconvenience fully.
Summary of the invention
The objective of the invention is to: a kind of leakage simple in structure, difficult, a kind of easily novel cutoff valve spool of installation and maintenance connecting sleeve mechanism are provided, overcome the existing defective that is difficult for closing fully dead, easy leakage, installation and maintenance inconvenience of existing stop valve spool connecting sleeve mechanism.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of novel cutoff valve spool connecting sleeve mechanism; It is made up of valve body, valve seat, spool, spool connecting sleeve, seal ring, O RunddichtringO, conehead, screw thread, connection chamber, oil outlet; There is a valve body in spool connecting sleeve mechanism; In the intermediate portion of valve body one connection chamber is arranged, connection chamber links to each other with oil outlet; On the same axis of valve body, connection chamber, be connected with valve seat, valve seat is provided with through hole, and the right part of through hole is the hole of taper, in the installed inside of cone shape hole the O RunddichtringO is arranged; On the valve seat opposing side, be connected with spool; Left end position at spool is connected with conehead; The tapering of conehead is identical with the tapering of valve seat right part cone shape hole; Right-hand member at spool is connected with screw thread, and the spool connecting sleeve is installed in the right-hand member position of valve body through screw thread, and the joint between valve body, spool, spool connecting sleeve is provided with seal ring.
Beneficial effect: because the present invention has adopted mechanism's mode of a cover two sealings of spool connecting sleeve, seal ring and O RunddichtringO; So; Stop valve spool connecting sleeve mechanism have be difficult for to leak, simple in structure, install and maintain advantage easily; Effectively overcome existing difficult the closing fully extremely of existing stop valve spool connecting sleeve mechanism, the defective of leak easily, installation and maintenance are inconvenient.
