Abstract
The utility model discloses the adjustable float valve plate of a kind of axial position.This float valve plate comprises valve plate body, and wherein, described valve plate body adopts split-type structural in the axial direction, and concrete structure is, valve plate body comprises the sealed valve core that sealing plate and middle part connect, and sealing plate and sealed valve core removably connect in the axial direction.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of float valve plate for butterfly valve.
Background technique
Valve is the parts for pipe-line system break-make and flow control, now in many fields such as oil, chemical industry, metallurgy, water power, is applied widely.
Butterfly valve generally includes valve body operating panel, the worm-and-wheel gear being connected with operating panel, the valve shaft being connected with worm screw, by valve shaft drive the valve plate that opens and closes, be arranged on the circumferential valve body of valve plate, be arranged in valve body and with the valve seat of valve plate fitted seal.
And at present, for the valve shaft of butterfly valve seal to all without float function, cannot realize the adjusting of valve plate axial position, therefore, in use in order to ensure the reliability of valve seal, very high to the requirement on machining accuracy of valve seal pair.
Model utility content
The utility model provides a kind of axial position adjustable float valve plate.
It is as follows that the utility model solves the technological scheme that its technical problem adopts:
A kind of float valve plate, comprises valve plate body, and wherein, described valve plate body adopts split-type structural in the axial direction, and concrete structure is, valve plate body comprises the sealed valve core that sealing plate and middle part connect, and sealing plate and sealed valve core removably connect in the axial direction.
The beneficial effects of the utility model: the utility model adopts split-type structural, the size of valve plate body self is adjustable, in the time installing and use, if contacting of valve plate body and valve seat can not reliable sealing, can the axial dimension of valve plate body entirety be increased by adjusting, closely cooperate and realize reliable sealing with valve seat, otherwise, if the tension that coordinates of valve plate body and valve seat, valve plate body opens and closes and is easy to damage valve seat, can the axial dimension of valve plate body entirety be reduced by adjusting, to reduce the wearing and tearing to valve seat on the basis of reliable sealing.Adjustable while installing and using due to this valve plate body, can compensating axial machining error, therefore just reduce the requirement to processing, possess practicability.Sealing plate removably connects with sealed valve core, easy installation and removal.
Further, sealing plate and sealed valve core bolt connection in the axial direction.Bolt fastening structure is simple, also convenient operation need to regulate valve plate axial dimension time.
Further, sealed valve core side is provided with the first cavity, in the first cavity, is provided with stage clip, described stage clip one end fixing seal plate, and the other end is fixed described sealed valve core.Stage clip is given component effect to valve seat direction of sealed valve core all the time, can guarantee the reliable sealing of sealed valve core and valve seat.
Further, sealed valve core radially cylindrical is provided with the second cavity, in the second cavity, is provided with seal ring, and sealing plate outer rim is the boss of gluing, sealing circle.Or sealing plate radially cylindrical arranges the second cavity, is provided with seal ring in the second cavity, sealed valve core outer rim is the boss structure of the described seal ring of laminating.The first seal ring guarantees that the unlikely cylindrical from sealed valve core of the medium of introducing leaks.
Further, the radially cylindrical of sealed valve core is the seal ring being sealed and matched with elastic seat, and described seal ring is spherical crown shape.The seal ring of sealed valve core is spherical crown shape, in the time of work, sealed valve core and valve seat even contact, between sealed valve core and valve seat, produce uniform active force, when valve plate body opens and closes, sealed valve core is little to the wearing and tearing of valve seat, and the application's sealing means is easy to process, even if valve seat has wearing and tearing, also can make sealed valve core and valve seat reliable sealing by the mode of grinding.
Further, between sealing plate and sealed valve core, have gap, sealed valve core inner circle is not less than the distance of sealed valve core inner circle to sealed valve core and elastic seat surface of contact to the distance of boss.Make to have gap between sealing plate and sealed valve core, in use, can introduce medium between sealing plate and sealed valve core, and when sealed valve core inner circle equals sealed valve core inner circle to the distance of sealed valve core and elastic seat surface of contact to the distance of boss, ensure that the medium introduced equals the area of outer medium to active force outside sealed valve core to the area of active force inside sealed valve core, can offset outer medium to active force outside sealed valve core; If sealed valve core inner circle is greater than the distance of sealed valve core inner circle to sealed valve core and elastic seat surface of contact to the distance of boss, the medium of introducing outside offsetting medium to active force outside sealed valve core in, also can produce a sealing force near valve seat to sealed valve core, further guarantee reliable sealing.
