Abstract
The invention discloses a clamping butterfly valve body. The upper part and the lower part of a cavity of the valve body are respectively provided with a rotating shaft hole of a valve column, two peripheral edges of the inner peripheral surface of the cavity of the valve body matched with a valve plate are provided with a boss respectively, the inner peripheral surface and the peripheral edges of the two bosses form an arc-shaped sealing surface, and crossing parts of the arc-shaped sealing surface and the rotating shaft holes of the valve column are provided with a widened boss. Since the two edges of the inner peripheral surface of the cavity of the valve body matched with the valve plate are provided with the bosses and are processed into the arc-shaped surface, the valve plate is assembled into an arc-shaped sealing strip via a special valve plate assembly tool during assembly and is then rotated until the end of the valve body is matched with the end of the valve plate, and the assembly is easier and more convenient. Due to sealing of the arc-shaped surface, the sealing surface is matched better.
Description
Technical field
The present invention relates to valve field, specifically, relate to a kind of clip butterfly valve body.
Background technique
The clip butterfly valve is a kind of valve that is used for the usefulness that conduct is blocked or regulated on the pipelines such as fire-fighting, plumbing, ventilation, oil, chemical industry, medicine, iron and steel; Constitute by valve body and valve plate as the one of which; On valve plate, possess a rotating shaft, the valve plate rotating shaft is installed in the rotary shaft hole of valve body valve rod, and an end of rotating shaft is protruding from the rotary shaft hole of valve body; And by driving device controls valve plate rotation, thereby the switching of control butterfly valve.This butterfly valve couples together the snap-ring groove on valve body and the pipeline through 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 leans on valve plate to wrap up; Cause easily that valve operation moment is excessive, the valve plate wearing and tearing, can only guarantee the low pressure seal effect.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency of above-mentioned existing technology, and a kind of clip butterfly valve body of ball face sealing is provided.
The technological scheme that the present invention adopted is:
A kind of clip butterfly valve body; Body cavity is provided with the rotary shaft hole of valve rod up and down respectively; Two peripheries of the inner peripheral surface that said body cavity cooperates with valve plate are boss; Said inner peripheral surface and two boss peripheries form the camber sealing surface, and the position that the rotary shaft hole of said camber sealing surface and valve rod intersects is provided with widens boss.
Compared with prior art, the invention has the beneficial effects as follows:
Clip butterfly valve body of the present invention is owing to make the inner peripheral surface both sides of body cavity and valve plate cooperation place boss and be processed into cambered surface, and when assembling, the valve plate assembly tooling of usefulness special use is packed valve plate in the camber sealing strip; Rotation makes valve end cooperate with the valve plate end, and assembling is simple more, convenient, owing to be the cambered surface sealing; Sealing surface cooperates better, reduces the operational torque of valve, and tight more characteristic is closed in the cambered surface sealing more; Make that the sealability of valve is better; The bidirectional bearing ability is high, zero leakage, long service life.
Description of drawings
Fig. 1 is a longitudinal sectional view of the present invention;
Fig. 2 is a transverse sectional view of the present invention;
Fig. 3 is a sealing surface schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done and to further describe.
Shown in Fig. 1-3; Valve body 1 inner chamber of the present invention is provided with the rotary shaft hole 3 of valve rod up and down respectively; Two peripheries of the inner peripheral surface that said valve body 1 inner chamber cooperates with valve plate are boss 2; Said inner peripheral surface and two boss peripheries form camber sealing surface 4, and the position that the rotary shaft hole of said camber sealing surface and valve rod intersects is provided with widens boss 5.
Clip butterfly valve body of the present invention is owing to make the inner peripheral surface both sides of body cavity and valve plate cooperation place boss and be processed into cambered surface; When assembling; The valve plate assembly tooling of usefulness special use is packed valve plate in the camber sealing strip; Rotation makes valve end cooperate with the valve plate end, and assembling is simple more, convenient.The position that the rotary shaft hole of camber sealing surface and valve rod intersects is provided with widens the valve plate that boss can further limit after the assembling and laterally moves, and makes that the sealability of valve is better, and the bidirectional bearing ability is high, zero leakage.
Embodiment recited above describes the preferred embodiment for the present invention; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention; Common engineers and technicians make technological scheme of the present invention in related domain various distortion and improvement all should belong to protection scope of the present invention.
