Abstract
The utility model relates to a valve suitable for various pipelines, in particular to a fixed ball valve. The fixed ball valve comprises a worm gear assembling component, a valve body, a valve cover, a ball body and a sealing ring. The ball body is arranged in the valve body with sealing by the valve cover, the ball body is axially connected on the valve body by an upper valve rod and a lower valve rod. The worm gear assembling component is arranged above the upper valve rod by a sealing pressing cover and a support bracket. The sealing ring is movably arranged on the periphery of the ball body. The outer side of the sealing ring is arranged with a valve base closely to the periphery of the ball body and an o-shaped sealing ring is arranged above the valve body and the outer side of the valve base is arranged with a spring. The outer portion of the sealing ring of the utility model is arranged with the sealing valve base, the O-shaped sealing ring and the spring device to compensate the ordinary abrasion of the sealing ring to improve the sealing performance and the service life of the ball valve. The sealing ring is movable and thus the repair is convenient with easy disassembling and changing. The driving force of the worm gear driving device is powerful and the starting and the stopping are convenient and flexible.
Description
Technical field
The utility model is a kind of valve that is applicable on the various pipelines, particularly a kind of Fixed ball valve.
Background technique
Ball valve of the prior art because the sealability of seal ring is bad, causes the fair wear and tear of seal ring easily, has reduced the working life of ball valve; In addition, the spheroid in the ball valve, the less stable of its orientation type has influenced the using effect of ball valve.
Summary of the invention
The purpose of this utility model is that invention is a kind of by the function of worm and gear transmission to realize that spheroid reaches unlatching or closes around the 90 degree rotations of valve body center line, and outside seal ring, increase seal valve seat, seal with O ring and spring assembly, the fair wear and tear of compensation sealing circle is to improve the sealability and the working life of ball valve.
The utility model is realized as follows: described Fixed ball valve comprises worm gear component, valve body, valve gap, spheroid and seal ring, spheroid is located in the valve body by valve gap is close, spheroid is coupling on valve body by upper valve rod and lower valve rod, above upper valve rod, be provided with the worm gear component by sealing gland and support, seal ring is located at the periphery of spheroid versatilely, the outside at seal ring is provided with valve seat, valve seat is close to the periphery of spheroid, above valve seat, be provided with O-ring seals, be provided with spring in the outside of valve seat.
This ball valve rotatablely moves to reach around valve body center line 90 degree by spheroid and opens or close, rotatablely moving of spheroid is that driving mechanism by the worm gear component is realized, spheroid is rotated counterclockwise when spacing around the valve body center line, spheroid passage and valve two ends channel vertical, and medium channel is cut off, valve is promptly closed, otherwise, the spheroid passage will with valve body two ends channel parallel, passage is connected, valve is opened, and medium can pass through.
Good effect of the present utility model is as follows: the seal arrangement of this ball valve is more advanced, and sealing ring material adopts reinforced TFE, has improved Applicable temperature than common teflon, can reach 180 ℃; Seal ring increases seal valve seat, O-ring seals and spring assembly outward, with the fair wear and tear of compensation sealing circle, improves the sealability and the working life of ball valve; Because of seal ring is movable, thus easy to maintenance, be easy to dismounting and change; The driving force of worm gearing is huge, opens and closes light and flexible; When standard-sized sheet and complete shut-down, the sealing surface of spheroid and seal ring can be by valve seat and media isolated, so the medium that high speed flow is crossed can not cause the erosion to seal ring; The spheroid of this valve is to adopt to go up the lower support location, has guaranteed the stability that spheroid rotates.
