Abstract
A check valve with a guide cylinder is characterized in that a guide device of a valve clack comprises a valve bonnet, the guide cylinder, a spring and a gasket, wherein the valve bonnet is arranged in the middle of a valve body, the gasket is pressed on the upper portion of the valve bonnet, the guide cylinder is arranged in the center of the valve body, the valve clack is provided with a hollow guide shaft inserted in the guide cylinder, the spring is arranged in the guide cylinder and the guide shaft, the valve clack can be rest under the action of the spring. Two symmetric sections are assembled to form the valve body, two middle flanges are arranged in the middle of the valve body, a sealing ring is arranged between the two sections of the valve body, the two sections of the valve body are fixedly connected with each other by a bolt via the flanges, two inlet and outlet pipeline connectors with flanges are respectively arranged at the upper end and the lower end of the valve body and are connected with water inlet and outlet pipes by the flanges, and an inlet channel valve port of the valve body is in contact with the valve clack elastically. High-pressure media open the valve clack in a jacking manner when the valve runs, deflection of the valve clack is prevented owing to the fact that a shaft of the valve clack moves along an inner cylindrical wall, eccentric impact is prevented, accordingly, the reliability of the valve clack is improved, and the service life of the valve is prolonged.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, particularly relates to a kind of safety check that guide cylinder is set that is applied in the pipeline system.
Background technique
In existing technology, valve in the production mainly is for pipeline system control media pressure, flow and the flow direction, it in use needs regular opening and closing, sealability will descend in use for some time, particularly because opening and closing repeatedly, make the sealing system of valve produce wearing and tearing, valve will not be in sealing state this moment, thereby cause scrapping of product, and the valve of this sealing configuration is higher to processing request, and valve is a kind of engineering goods that are widely used, production and processing meets the valve that sealability requires, need to adopt day by day expensive non-ferrous metal, such as brazen valve body, valve seat, valve rod, bonnet, the spool ball, fill bonnet, purple adapter made of copper etc.Make the raw material serious waste, these factors have all caused the manufacture cost of ball valve too high.Particularly the flap of existing safety check is without guide mechanism, and valve is in operation to produce and swings, and causes easily flap to block and damage, and spring is also fragile, and flap carries out frequent eccentric bump to valve body sealing surface, and life of valve is shortened.
Summary of the invention
The purpose of this utility model is to be improved for the shortcoming of technological deficiency of the prior art and existence and problem, a kind of safety check that guide cylinder is set is provided, make it in use, it reaches the requirement that sealability is more excellent, adjusting is convenient, to improve the working life of valve.
The purpose of this utility model is achieved by following technological scheme:
A kind of safety check that guide cylinder is set, comprise valve body, flap, spring, guide cylinder, flange, valve gap, seal ring, pad, bolt, flange, it is characterized in that described flap guiding device, comprise valve gap, guide cylinder, spring, pad, wherein valve gap is located at the valve body middle part, pad is pressed in valve gap top, guide cylinder is located at the center of valve body, flap is located at guiding device one side, can vertically move and reset, flap has one section hollow guiding axle to be inserted in the guide cylinder, is provided with the spring that flap is resetted in guide cylinder and the axis of guide.Described valve body is assembled for symmetrical two sections, and the middle part of valve body is provided with two spacer flangers, is provided with seal ring between two sections valve bodies, and bolt is fixedly connected with two sections valve bodies in aggregates by flange.The upper/lower terminal of valve body is respectively established a flanged (FLGD) inlet/outlet pipe pipeline joint, and valve body upper and lower end pipe joint connects turnover water pipe by flange, and the inlet passage valve port of valve body is touched by flap elastic force.
When valve moved, high-pressure medium backed down flap, because the flap axle moves along the tubular inwall, flap beat can not occur, and has avoided eccentric bump, thereby has improved the reliability of flap work, has prolonged the working life of valve.
Usefulness of the present utility model is, flap is done elevating movement along the tubular pilot hole, the secondary spring buffering, make flap lifting centering, steady, avoided between flap and the valve body sealing surface swinging the off-centre bump that forms because of flap, thereby improved the reliability of flap work, prolonged the working life of valve.
