Abstract
The utility model discloses a valve body for a grooved butterfly valve. A rotating shaft hole of a valve rod is formed on each of the upper and lower parts of an inner cavity of the valve body. The inner peripheral surface of the inner cavity of the valve body is matched with a valve plate, and the two peripheries of the inner peripheral surface are lug bosses. The inner peripheral surface and the lug boss peripheries form cambered sealing surfaces. Widened lug bosses are arranged at the intersection positions of the cambered sealing surfaces and the rotating shaft holes of the valve rod. According to the valve body for the grooved butterfly valve, the two sides of the inner peripheral surface on the matched part of the inner cavity of the valve body and the valve plate are machined into cambered surface lug bosses, and when the valve is assembled, the valve plate is arranged in a cambered sealing strip through a special valve plate assembly tool, and is rotated to realize matching between the end parts of the valve body and the valve plate, so that the valve can be simply and conveniently assembled; and due to the adoption of cambered surface sealing, so that the sealing surfaces are well matched.
Description
Technical field
The utility model relates to valve field, specifically, relates to a kind of clip butterfly valve body.
Background technique
The clip butterfly valve be a kind of on the pipelines such as fire-fighting, plumbing, ventilation, oil, chemical industry, medicine, iron and steel as the valve of the usefulness of blocking or regulating, it generally is made of valve body and valve plate, possesses a rotating shaft at valve plate, the valve plate rotating shaft is installed in the rotary shaft hole of valve body valve rod, one end of rotating shaft is protruding from the rotary shaft hole of valve body, and by the rotation of drive unit control valve plate, thereby the switching of control butterfly valve.This butterfly valve couples together the snap-ring groove on valve body and the pipeline by clip, is installed on the pipeline.The body cavity of this butterfly valve is generally straight-through type, form the cylindricality sealing with valve plate, the assembling difficulty of butterfly valve body and valve plate, in the using process because the rubber compression seal that wraps up by valve plate, cause easily that valve operation moment is excessive, the valve plate wearing and tearing, can only guarantee the low pressure seal effect.
The model utility content
Technical problem to be solved in the utility model is, overcomes above-mentioned the deficiencies in the prior art, and a kind of clip butterfly valve body of ball face sealing is provided.
The technological scheme that the utility model adopts is:
A kind of clip butterfly valve body, body cavity arranges respectively up and down the rotary shaft hole of valve rod, two peripheries of the inner peripheral surface that described body cavity cooperates with valve plate are boss, described inner peripheral surface and two boss peripheries form the camber sealing surface, and the position that the rotary shaft hole of described camber sealing surface and valve rod intersects arranges widens boss.
Compared with prior art, the beneficial effects of the utility model are:
Clip butterfly valve body of the present utility model is owing to making the inner peripheral surface both sides of body cavity and valve plate cooperation place boss and being processed into cambered surface, when assembling, with the valve plate assembly tooling of special use valve plate is packed in the camber sealing strip, rotation makes valve end cooperate with the valve plate end, assembling is more simple, convenient, owing to being the cambered surface sealing, sealing surface cooperates better, reduce the operational torque of valve, tighter characteristic is more closed in the cambered surface sealing, so that the sealability of valve is better, the bidirectional bearing ability is high, zero leakage, long service life.
Description of drawings
Fig. 1 is the utility model longitudinal sectional view;
Fig. 2 is the utility model transverse sectional view;
Fig. 3 is the utility model sealing surface schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Figure 1-3, the utility model valve body 1 inner chamber arranges respectively up and down the rotary shaft hole 3 of valve rod, two peripheries of the inner peripheral surface that described valve body 1 inner chamber cooperates with valve plate are boss 2, described inner peripheral surface and two boss peripheries form camber sealing surface 4, and the position that the rotary shaft hole of described camber sealing surface and valve rod intersects arranges widens boss 5.
Clip butterfly valve body of the present utility model is owing to making the inner peripheral surface both sides of body cavity and valve plate cooperation place boss and being processed into cambered surface, when assembling, with the valve plate assembly tooling of special use valve plate is packed in the camber sealing strip, rotation makes valve end cooperate with the valve plate end, and assembling is more simple, convenient.The position that the rotary shaft hole of camber sealing surface and valve rod intersects arranges widens valve plate transverse shifting after boss can further limit assembling, so that the sealability of valve is better, the bidirectional bearing ability is high, zero leakage.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in related domain various distortion and improvement all should belong to protection domain of the present utility model.
Claims (1)
1. clip butterfly valve body, body cavity arranges respectively up and down the rotary shaft hole of valve rod, it is characterized in that, two peripheries of the inner peripheral surface that described body cavity cooperates with valve plate are boss, described inner peripheral surface and two boss peripheries form the camber sealing surface, and the position that the rotary shaft hole of described camber sealing surface and valve rod intersects arranges widens boss.
