Abstract
The utility model discloses a ball valve, which comprises a valve body, a valve cover, a ball body, a valve rod, a handle and movable joints, wherein the valve cover is fixedly arranged on the upper end surface of the valve body, the ball body is arranged in the valve body, one end of the valve rod penetrates through the valve cover to be linked with the ball body in the valve body, the handle is fixedly arranged at the other end of the valve rod exposing outside the valve cover, the movable joints are arranged at the two ends of the valve body, a sealing ring is arranged between the movable joints and the ball body and is adhered to the ball body, a spring is arranged between the sealing ring and the movable joints, and the movable joint is in detachable connection and match with the valve body; therefore, when the sealing ring is subjected to little or concentrated wear, the tightness of the sealing ring can be adjusted automatically under the action of elastic compensation force of the spring by the sealing ring, so that the service life of the sealing ring is greatly prolonged; and when the sealing ring is subjected to serious wear and needs to be replaced, the movable joints at the two ends of the valve body are opened to maintain or replace the sealing ring, so that the ball valve is simple and convenient.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of ball valve.
Background technique
At present, existing ball valve sealing circle is normally fixed, disposable only use, there are wearing and tearing to leak slightly, and are difficult to maintain and replace, because ball valve is generally integrated setting, must one when installing and changing save in order and carry out, complicated loaded down with trivial details, maintenance and replacing accessory difficulty are so will cause whole ball valve to be scrapped in case seal ring is damaged.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of and has been convenient to installation and maintenance and changes accessory and can adjust the ball valve of sealing ring tightness automatically.
For achieving the above object, the utility model provides a kind of ball valve, comprise valve body, valve gap, spheroid, valve rod, handle, movable joint, described valve gap is installed in the valve body upper-end surface, spheroid is located in the valve body, one end of valve rod passes valve gap and the spheroid interlock that is located in the valve body, valve rod is exposed on the outer the other end of valve gap and is installed with handle, described movable joint is located at two ends of valve body, be provided with seal ring between movable joint and the spheroid, described seal ring and spheroid are fitted, and are provided with spring between seal ring and the movable joint, and cooperate for removably connecting between described movable joint and the valve body.
The valve body inner peripheral surface that is detachably connected as that the utility model can further be set between described movable joint and the valve body is provided with loose joint and colludes piece, and the outer peripheral surface of movable joint is provided with and colludes piece with described loose joint and collude the loose joint catching groove of joining mutually.
The utility model also can further be set to be provided with sealing nut between described spheroid and the valve body, and described sealing nut is set on the valve rod, and the inner peripheral surface of sealing nut and spheroid applying, and the outer peripheral surface and the valve body of sealing nut are spirally connected.
The beneficial effects of the utility model are: adopt said structure, when seal ring is subjected to a small amount of or concentrated wear, seal ring can be adjusted the sealing of seal ring automatically under the elastic compensating power effect of spring, prolonged the working life of seal ring widely, when ring wear more seriously need be changed, the movable joint at valve body two ends can be opened, repair or replace seal ring, owing to cooperate for removably connecting between described movable joint and the valve body, so it is when installation and maintenance and replacing accessory, simple and convenient.
Description of drawings
Fig. 1 is a section decomposing schematic representation of the present utility model.
Embodiment
Provided a kind of ball valve as shown in Figure 1, comprise valve body 1, valve gap 2, spheroid 3, valve rod 4, handle 5, movable joint 6, described valve gap 2 is installed in valve body 1 upper-end surface, spheroid 3 is located in the valve body 1, one end of valve rod 4 passes valve gap 2 and spheroid 3 interlocks that are located in the valve body 1, valve rod 4 is exposed on valve gap 2 the other end outward and is installed with handle 5, described movable joint 6 is located at the two ends of valve body 1, be provided with seal ring 7 between movable joint 6 and the spheroid 3, described seal ring 7 is fitted with spheroid 3, be provided with spring 8 between seal ring 7 and the movable joint 6, and cooperate for removably connecting between described movable joint 6 and the valve body 1, described movable joint 6 and valve body 1 valve body 1 inner peripheral surface that is detachably connected as is provided with loose joint and colludes piece 11, the outer peripheral surface of movable joint 6 is provided with and colludes piece 11 with described loose joint and collude the loose joint catching groove 61 of joining mutually, be provided with sealing nut 9 between described spheroid 3 and the valve body 1, described sealing nut 9 is set on the valve rod 4, and the inner peripheral surface of sealing nut 9 and spheroid 3 are fitted, and the outer peripheral surface of sealing nut 9 and valve body 1 are spirally connected.
Adopt said structure, when seal ring 7 is subjected to a small amount of or concentrated wear, seal ring 7 can be adjusted the sealing of seal ring 7 automatically under the elastic compensating power effect of spring 8, prolonged the working life of seal ring 7 widely, when seal ring 7 wearing and tearing seriously need to change, the movable joint 6 at valve body 1 two ends can have been opened, repair or replace seal ring 7, owing to cooperate for removably connecting between described movable joint 6 and the valve body 1, so installation and maintenance are simple and convenient during with the replacing accessory.
