Abstract
The utility model discloses a kind of ball valve, comprise valve body, valve seat, upper valve rod and lower rotary shaft; Described valve seat is arranged on the inside of valve body; Spheroid is provided with between described valve seat; Described spheroid upper end is provided with upper valve rod, and its lower end is provided with lower rotary shaft; In described valve seat, two ends are provided with belleville spring; Described belleville spring side is provided with bellows; Described bellows one end is welded in valve body, and the other end is welded on valve seat side, and is connected with belleville spring; The utility model, by the bellows arranged, makes the sealing of valve body and valve base chamber more remarkable; It is simple and reasonable, easy to use, the distortion of belleville spring and bellows together provides the initial sealing power in ball valve, and meanwhile, the sphere push valve seat expanded at high operating temperatures moves to both sides, compression belleville spring and bellows, sealing is reliable, and elastic compensating scope is large, and in three dimensional space flexible movements, working life extends greatly, and operating characteristics significantly improves.
Description
Technical field
The utility model relates to a kind of ball valve, belongs to valve technology field.
Background technique
at present, ball valve is in the extensive use of the industries such as petrochemical industry, long-distance transport pipes and urban heat supplying.The sealing configuration of the hard density ball valve of high temperature is the key factor affecting its sealability, under the effect of temperature and pressure, when interaction force between valve seat and spheroid changes, suitable sealing configuration and physical dimension is adopted to compensate the change produced, one of important measures ensureing its sealability.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of simple and reasonable, easy to use, sealing is reliable, and elastic compensating scope is large, and in three dimensional space flexible movements, working life extends greatly, the ball valve that operating characteristics significantly improves.
(2) technological scheme
Ball valve of the present utility model, comprises valve body, valve seat, upper valve rod and lower rotary shaft; Described valve seat is arranged on the inside of valve body; Spheroid is provided with between described valve seat; Described spheroid upper end is provided with upper valve rod, and its lower end is provided with lower rotary shaft; In described valve seat, two ends are provided with belleville spring; Described belleville spring side is provided with bellows; Described bellows one end is welded in valve body, and the other end is welded on valve seat side, and is connected with belleville spring.
Further, described valve seat is provided with two.
Further, described belleville spring is provided with four.
Further, described bellows is provided with four.
Further, described upper valve rod is corresponding with lower rotary shaft to be arranged.
(3) beneficial effect
Compared with prior art, it has following beneficial effect to the utility model: ball valve of the present utility model, by the bellows arranged, makes the sealing of valve body and valve base chamber more remarkable; It is simple and reasonable, easy to use, the distortion of belleville spring and bellows together provides the initial sealing power in ball valve, and meanwhile, the sphere push valve seat expanded at high operating temperatures moves to both sides, compression belleville spring and bellows, sealing is reliable, and elastic compensating scope is large, and in three dimensional space flexible movements, working life extends greatly, and operating characteristics significantly improves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-valve body; 2-bellows; 3-belleville spring; 4-valve seat; 5-upper valve rod; 6-spheroid; 7-lower rotary shaft.
Embodiment
A kind of ball valve as shown in Figure 1, comprises valve body 1, valve seat 4, upper valve rod 5 and lower rotary shaft 7; Described valve seat 4 is arranged on the inside of valve body 1; Spheroid 6 is provided with between described valve seat 4; Described spheroid 6 upper end is provided with upper valve rod 5, and its lower end is provided with lower rotary shaft 7; In described valve seat 4, two ends are provided with belleville spring 3; Described belleville spring 3 side is provided with bellows 2; Described bellows 2 one end is welded in valve body 1, and the other end is welded on valve seat 4 side, and is connected with belleville spring 3.
Wherein, described valve seat 4 is provided with two; Described belleville spring 3 is provided with four; Described bellows 2 is provided with four; Described upper valve rod 5 is corresponding with lower rotary shaft 7 to be arranged.
Ball valve of the present utility model, by the bellows arranged, makes the sealing of valve body and valve base chamber more remarkable; It is simple and reasonable, easy to use, the distortion of belleville spring and bellows together provides the initial sealing power in ball valve, and meanwhile, the sphere push valve seat expanded at high operating temperatures moves to both sides, compression belleville spring and bellows, sealing is reliable, and elastic compensating scope is large, and in three dimensional space flexible movements, working life extends greatly, and operating characteristics significantly improves.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
