Abstract
The utility model relates to a ball valve with a fixed ball. The ball valve comprises a valve rod (1), a ball body (2), a valve body (3), a lower bearing (4), an upper bearing (5), a valve base (6) and a spring (7), wherein the valve rod (1) is arranged above the upper bearing (5), the upper portion of the ball body (2) is connected with the upper bearing (5), the lower portion of the ball body (2) is connected with the lower bearing (4), the ball body (2) is installed in the valve body (3) through the valve rod (1), the upper bearing (5) and the lower bearing (4), the valve base (6) is arranged between the ball body (2) and the valve body (3), and the spring (7) is arranged between the valve base (6) and the valve body (3). The ball valve with the fixed ball has the advantages that the weight of the ball body and production cost are reduced, and seal performance is better.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of fixedly spherical ball valve.
Background technique
Fixing spherical ball valve, be high-performance ball valve of new generation, be applicable to long-distance transport pipes and sorry industrial pipeline, its intensity, Anqiu, adverse environment resistant etc. have carried out special consideration when design, be applicable to various corrosivity and non-aggressive medium, be applicable to high pressure, heavy caliber occasion.Fixing ball valve is mainly used in the every field such as oil, chemical industry, iron and steel, metallurgy and electric power, valve with respect to other control valve track media circulation, fixedly to have resistance of medium little for spherical ball valve, the advantage such as easy to operate, the valve body of the fixedly spherical ball valve in technology adopts complete spheroid now, cause the weight that has increased spheroid in the processing of sphere production process, caused the waste of material simultaneously, also increased on the other hand manufacturing cost.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of lighter spheroid, sealability fixing spherical ball valve is preferably provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of fixedly spherical ball valve, comprise valve rod, spheroid, valve body, lower bearing, upper bearing (metal), valve seat and spring, described valve rod is arranged on valve inner by upper bearing (metal), the lower end of valve rod is fixed on spheroid, spheroid below is connected with lower bearing, spheroid is arranged at valve inner, between spheroid and valve body, is provided with valve seat, between valve seat and valve body, is provided with spring.
Further, described valve rod and valve seat are respectively and between valve body, be provided with seal ring.
Further, the corresponding spring position of described valve body is provided with cylindricality blind hole, and spring is placed in cylindricality blind hole.
The utlity model has following advantage: the utility model adopts incomplete spheroid, do not affecting on the basis of spheroid use, alleviated spheroid weight, reduce production costs, by be provided with seal ring between valve rod and valve seat, thereby make sealability of the present utility model better, at the corresponding spring position of valve body, be provided with cylindricality blind hole simultaneously, spring is placed in cylindricality blind hole, makes Compress Spring location more firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve rod, 2-spheroid, 3-valve body, 4-lower bearing, 5-upper bearing (metal), 6-valve seat, 7-spring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of fixedly spherical ball valve, comprise valve rod 1, spheroid 2, valve body 3, lower bearing 4, upper bearing (metal) 5, valve seat 6 and spring 7, described valve rod 1 is arranged on valve body 3 inside by upper bearing (metal) 5, the lower end of valve rod 1 is fixed on spheroid 2, spheroid 2 belows are connected with lower bearing 4, spheroid 2 is arranged at valve body 3 inside, between spheroid 2 and valve body 3, be provided with valve seat 6, between valve seat 6 and valve body 3, be provided with spring 7, wherein, spheroid 2 has all been done necessarily and has been eliminated up and down, spheroid 2 is arranged in the situation that does not affect use, alleviated the weight of spheroid itself, saved material, reduced cost of production.
Further, between described valve rod 1 and valve seat 6, be provided with seal ring, by this, be arranged so that valve rod 1 and valve seat 6 fitted seal are better, spheroid 2 coordinates tightr with valve seat 6, valve seat 6 coordinates tightr with valve body 3, thereby overall sealing performance is well improved.
Further, the corresponding spring of described valve body 37 positions are provided with cylindricality blind hole, and spring 7 is placed in cylindricality blind hole, make spring 7 location more firm.
