Abstract
The utility model relates to a check valve head, which comprises a body, the body is installed in the inner chamber of valve body, and the outer edge of body with the inner wall of valve body is hugged closely, the body with the contact department of valve body is equipped with one deck pottery wearing layer, the surface of wearing layer with the inner wall of valve body is hugged closely, the central point of body is equipped with the valve rod, be equipped with the rubber packing pad on the body, the outer edge of rubber packing pad with the inner wall of valve body is hugged closely, the utility model provides a check valve head's advantage lies in: through set up one deck ceramic wearing layer in the contact department of body and valve body, the body reduces the wearing and tearing to the body when coming back and forth movement in the valve body, improves the gas tightness, prolongs the life of body.
Description
Technical field
The utility model relates to the one-way valve field, relates in particular to a kind of one-way valve valve head.
Background technique
One-way valve is that fluid can only flow along water intake, and the water outlet medium but can't reflux, and is commonly called as one-way valve.One-way valve is exactly safety check, and the Swing check valve mounting point is unrestricted, usually is installed on horizontal pipeline, but also can be installed on vertical duct or incline the material pipeline on.When safety check is installed, should be specifically noted that the media flow direction, should make the direction of arrow of indicating on medium proper flow direction and the valve body consistent, otherwise the proper flow that will block medium.Bottom valve should be installed in the bottom of pump sump pipeline.During closure of check ring, can in pipeline, produce water hammer pressure, can cause the damage of valve, pipeline or equipment when serious, especially for large mouthful of pipeline or pressure duct, select user's hig diligence so should cause safety check.Safety check is only for the unidirectional keying valve that prevents flowing medium adverse current on all kinds of pipelines or the equipment.
In the prior art, the valve head of one-way valve often rubs back and forth with valve interior wall, after long-time the use, causes easily the valve head wearing and tearing, makes valve head cause poor air-tightness in movement process, makes the operational effect variation of one-way valve, and the reduction in working life.
The model utility content
In view of this, be necessary to provide a kind of assurance good tightness, and the one-way valve valve head that increases the service life.
The utility model is to realize like this, the one-way valve valve head, comprise body, described body is installed in the inner chamber of valve body, and the outer of body and the inwall of described valve body are close to, the contacting point of described body and described valve body is provided with one deck ceramic wearing coat, and the outer surface of described wearing layer and the inwall of described valve body are close to.
Further, the center portion of described body is provided with valve rod.
Further, described body is provided with rubber gasket, and the outer of described rubber gasket and the inwall of described valve body are close to.
The advantage of the one-way valve valve head that the utility model provides is: by the contacting point at body and valve body one deck ceramic wearing coat is set, when body moves back and forth, reduces the wearing and tearing to body in valve body, improve tightness, prolong the working life of body.
Description of drawings
Fig. 1 is the structural representation of the utility model one-way valve valve head.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is the structural representation of the utility model one-way valve valve head.
Described one-way valve valve head, comprise body 10, described body 10 is installed in the inner chamber of valve body 20, and the inwall of the outer of body 10 and described valve body 20 is close to, described body 10 is provided with one deck ceramic wearing coat 11 with the contacting point of described valve body 20, and the inwall of the outer surface of described wearing layer 11 and described valve body 20 is close to.
The center portion of described body 10 is provided with valve rod 30, and described body 10 is provided with rubber gasket 40, and the inwall of the outer of described rubber gasket 40 and described valve body 20 is close to, and improves the tightness of one-way valve.
By the contacting point at body 10 and valve body 20 one deck ceramic wearing coat 11 is set, when body 10 moves back and forth, reduces the wearing and tearing to body 10 in valve body 20, improve tightness, prolong the working life of body 10.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
