Abstract
The invention discloses a corrugated pipe ball valve. One end of a transmission body (10) is connected with a valve body (11) and the other end is connected with a transmission cover (13); the transmission cover (13) is provided with a transmission nut (2) and a transmission screw rod (5) and the transmission nut (2) is connected with a hand wheel (1); a transmission shaft (9) is connected with a shifting fork (7); one end of a shifting pin (8) is fixed on the transmission screw rod (5) and the other end is inserted in the shifting fork (7); one end of a corrugated pipe (6) is fixed to and connected with the transmission cover (13) in a sealing way and the other end is fixed to and matched with the transmission screw rod (5) in a sealing way; and a sealing piece (4) is arranged on the transmission cover (13). The corrugated pipe is fixedly connected with the transmission cover and the transmission screw rod to realize seal between a valve rod and a valve cover; and the invention changes the dynamic seal of the prior art into static seal, thereby achieving the advantage of high-reliability seal.
Description
Technical field
The present invention relates to a kind of ball valve, particularly relate to a kind of bellows ball valve.
Background technique
A kind of bellows ball valve is arranged at present, and its structure is adopt to go up the helical guideway of lower valve rod, realize valve rod spheroid rotatablely move complex structure, guide rail inefficacy easy to wear.
Summary of the invention
Technical problem to be solved by this invention provides a kind of drive mechanism with the good bellows ball valve of sealing reliability.
In order to solve the problems of the technologies described above, bellows ball valve provided by the invention, comprise valve body, spheroid and transmission shaft, transmission body one end is connected with described valve body, the other end is connected with transmission cover, described transmission cover is provided with transmission nut, described transmission nut is connected with handwheel, described transmission cover is provided with and cooperates the drive lead screw that rotates and extend in the described transmission body with described transmission nut spiral, described transmission shaft is connected with shift fork, finger one end is fixed on the described drive lead screw, the other end is inserted in the described shift fork, bellows is sleeved on the described drive lead screw and an end and described transmission cover fixed seal connection, and the other end cooperates with described drive lead screw fixing seal, and described transmission cover is provided with the Sealing that acts on described drive lead screw.
Described transmission cover is provided with and acts on the guide pad that described drive lead screw leads and locatees.
Adopt the bellows ball valve drive mechanism of technique scheme, owing between drive lead screw and transmission cover, only make axial linear movement, finger on the drive lead screw drives the transmission shaft rotation by shift fork, thereby being rotated, spheroid realizes switching motion, so, the present invention adopts bellows to fixedly connected with transmission cover and drive lead screw and realizes sealing between valve rod and the valve gap, it is static seal that realization has the motive sealing of technology, in ball valve, become straight line motion into rotatablely moving, make to straight-line drive lead screw and rotate by the promotion of the finger on being fixed on shift fork, shift fork drives the spheroid rotation, bellows one end fixing seal is on drive lead screw, the other end and transmission cover fixing seal, realize static seal, also have Sealing simultaneously, reach double seal, it is static seal that realization has the motive sealing of technology, thereby has the good advantage of sealing reliability.
In sum, the present invention be a kind of realization the motive sealing of technology is arranged is static seal, thereby have that sealing reliability is good and easily manufactured, cost reduces, the bellows ball valve of reliable performance.
