Description
Technical Field
The utility model relates to the technical field of valves, specifically indicate an integral check valve clack.
Background
The valve clack is one of the main parts of the valve, and the opening and the closing of the valve are realized by the position change of the valve clack; in the lifting process of the valve clack, the change of the flow is in direct proportion to the stroke of the valve clack, and the valve clack is very suitable for adjusting the flow. The structural design of the valve clack is directly related to the service performance of the valve. The existing valve clack has poor sealing effect, is used for a long time, is impacted by fluid and has short service life.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide an integral check valve clack.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an integral check valve clack, includes the valve piece, be equipped with on the valve piece with valve rod complex jack, the one end that the jack was kept away from to the valve piece is equipped with the valve clack main part with disk seat complex, the valve clack main part includes first valve clack, second valve clack, third valve clack, first valve clack is the round platform structure, and the diameter size of first valve clack bottom is less than the diameter size at top, the bottom surface and the second valve clack of first valve clack are hugged closely, the cross-section of second valve clack is semi-circular, be equipped with the ring channel on the circumferencial direction of second valve clack, be equipped with the detachable elastic sealing body in the ring channel, the third valve clack is the cone form, first valve.
As an improvement, the valve clack main body is made of ceramics.
As an improvement, the outer side of the valve clack body is provided with a wear-resistant layer.
As an improvement, the wear-resistant layer is made of manganese-titanium alloy.
As an improvement, the middle part of the third valve clack is provided with an inwards concave structure.
As an improvement, a chamfer structure is arranged on the valve block.
Compared with the prior art, the utility model the advantage lie in: the three-section type valve clack main body structure has the advantages that the outer diameter size is gradually increased, the condition that the valve clack is corroded to influence the sealing performance can be overcome, the original sealing effect is unchanged, the combination part is firmer, and the service life is prolonged; the wear-resistant layer enhances the erosion resistance; the concave structure saves materials.
