Abstract

The utility model relates to a fixing ball valve which comprises a valve body, a valve seat, a valve stem, a ball and a handle, wherein the ball is arranged in the valve body, the valve seat is arranged between the ball and the valve body, the upper end of the ball is connected with the valve stem for rotating the ball, the other end of the valve stem is provided with the handle, and a sealing ring is arranged between the valve stem and the valve body. The fixing ball valve is characterized in that the ball is provided with a groove, the opening direction of the groove is perpendicular to the direction of an inner channel of the ball body, the sealing surface of the ball is provided with an arc surface which is concentric with the ball and has the diameter smaller than the diameter of the ball, and both ends of the arc surface are provided with planes perpendicular to the channel. By the above technical scheme, the fixing ball valve can reduce the production cost and the weight of the ball and does not affect the use of the ball.

Description

Fixing ball valve
Technical field
The utility model relates to a kind of ball valve, more particularly relates to a kind of fixing ball valve.
Background technique
Fixing ball valve is mainly used in every field such as oil, chemical industry, iron and steel, metallurgy and electric power, valve with respect to other control valve track media circulation, it is little that fixing ball valve has a resistance of medium, advantage such as easy to operate, what the spheroid of existing fixing ball valve adopted all is complete spheroid, increase the weight of spheroid like this in the spheroid processing process, caused the waste of material simultaneously, also increased cost of production on the other hand.
Summary of the invention
At the deficiency that prior art exists, it is a kind of when not influencing spheroid and use that the purpose of this utility model is to provide, and reduced cost of production, alleviates the fixing ball valve of the weight of spheroid.
For achieving the above object, the utility model provides following technological scheme: a kind of fixing ball valve, comprise valve body, valve seat, valve rod, spheroid and handle, spheroid is arranged in the valve body, is provided with valve seat between described spheroid and the valve body, and the spheroid upper end is connected with the valve rod for rotating sphere, the valve rod the other end is provided with handle, be provided with seal ring between valve rod and the valve body, it is characterized in that: described spheroid is provided with groove, and the opening direction of described groove is vertical with spheroid internal channel direction.
The beneficial effects of the utility model are: being arranged under the situation that does not influence use of spheroid, alleviated the weight of spheroid itself, and saved material, namely reduced cost of production.
The utility model further is set to: described groove constitutes by the opening plane vertical with the direction of passage and with the concentric curve bath of spheroid.
By adopting technique scheme, the slot opening end adopts the plane, and arranging like this is for spheroid can scrape off the impurity that is attached on the spheroid in the process of using, and the setting of curve bath is when saving material, does not also influence the normal use of spheroid.
The utility model further is set to: be provided with seal ring between described spheroid and the valve seat, be provided with seal ring between valve seat and the valve body, be provided with the compression spring between valve seat and the valve body.
By adopting technique scheme and since the compression spring with valve seat to the spheroid roof pressure, it is tightr to make that valve seat cooperates with spheroid, thereby makes valve seat and ball seal performance better.
The utility model further is set to: the corresponding compression of described valve body spring position is provided with the cylindricality blind hole, and described compression spring places in the cylindricality blind hole.
By adopting technique scheme, the compression spring places in the cylindricality blind hole, makes that compression spring location is more firm.
Description of drawings
Fig. 1 is the utility model embodiment overall structure figure;
Fig. 2 is the utility model embodiment valve body structure figure.
Embodiment
Shown in Fig. 1 ~ 2, the utility model discloses a kind of fixing ball valve, comprise valve body 1, valve seat 2, valve rod 3, spheroid 4 and handle 5, spheroid 4 is arranged in the valve body 1, be provided with valve seat 2 between described spheroid 4 and the valve body 1, spheroid 4 upper ends are connected with the valve rod 3 for rotating sphere 4, valve rod 3 the other ends are provided with handle 5, are provided with seal ring 6 between valve rod 3 and the valve body 1, and described spheroid 4 is provided with groove 41, the opening direction of described groove 41 is vertical with spheroid 4 internal channel directions, by adopting technique scheme, being arranged under the situation that does not influence use of spheroid alleviated the weight of spheroid itself, save material, namely reduced cost of production.
The utility model further is set to: described groove 41 constitutes by the opening plane 411 vertical with the direction of passage and with the concentric curve bath 412 of spheroid 4, by adopting technique scheme, groove 41 openings adopt the plane, arrange like this is can scrape off the impurity that is attached on the spheroid 4 for spheroid 4 in the process of using, the setting of curve bath 412 is when saving material, does not also influence the normal use of spheroid 4.
The utility model further is set to: be provided with seal ring 6 between described spheroid 4 and the valve seat 2, be provided with seal ring 6 between valve seat 2 and the valve body 1, be provided with compression spring 7 between valve seat 2 and the valve body 1, by adopting technique scheme, since the compression spring 7 with valve seat 2 to spheroid 4 roof pressures, it is tightr to make that valve seat 2 cooperates with spheroid 4, thereby makes that valve seat 2 and spheroid 4 sealabilities are better.
The utility model further is set to: described valve body 1 corresponding compression spring 7 positions are provided with cylindricality blind hole 11, described compression spring 7 places in the cylindricality blind hole 11, by adopting technique scheme, compression spring 7 places in the cylindricality blind hole 11, makes that compression spring 7 location are more firm.
