Abstract

The utility model relates to an indented ball valve which mainly solves the problems that an existing ball valve is high in production cost, short in service life and low in flow velocity. The indented ball valve comprises valve body, a valve seat, a valve rod and a ball body. The ball body is located in the valve body, the valve rod penetrates through the valve body to be connected with the ball body, the valve seat is arranged between the ball body and the valve body, the ball body is oval, the two end faces of a channel of the ball body are planes, a first flange and a second flange are installed at the two ends of the valve body respectively, and a through hole of the first flange and a through hole of the second flange are in the shape of a horn with the outer side larger and the inner side smaller. Because a flow channel of a valve element of the ball valve is narrow and is in the shape of an oval with the upper end and the lower end in planar transition, materials are effectively saved, and production cost is reduced; because the flanges of the valve body are arranged in the shape of the horn with the outer side larger and the inner side smaller, flow velocity is improved when mediums flow.

Description

The indentation ball valve
Technical field
The utility model relates to a kind of valve, refers in particular to a kind of indentation ball valve.
Background technique
The spheroid of ball valve is driven by valve rod, and the valve rotated around the axis of valve rod.Be mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid, wherein firmly seal between the metal seat valve of its V-type ball core of V-type ball valve and pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the media such as fibre-bearing, small solid particle.And the multi-pass ball valve not only interflow of control media, shunting, and switching of flowing to flexibly on pipeline also can be closed arbitrary passage and two other passage is connected simultaneously.
At present, the ball valve used on market, its spool is general ball shape, by two end faces are set on spool, then process passage, because end face is less, so channel diameter is longer, thereby causes waste of material, in addition when mounted, by flange, installed, the end face of flange is plane, and flow velocity is unaffected.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides a kind of indentation ball valve, solves existing ball valve and has the problem that cost of production is high, working life is short and flow velocity is slow.
The technical solution of the utility model is: a kind of indentation ball valve, comprise valve body, valve seat, valve rod and spheroid, described spheroid is positioned at valve body, described valve rod is connected with spheroid through valve body, described valve seat is located between spheroid and valve body, and described spheroid is oval, and the both ends of the surface of its passage are plane, the two ends of described valve body are equipped with the first flange and the second flange, and the through hole of described the first flange and the second flange is the horn shape that outer imperial palace is little.
Described valve body is formed by connecting by the first valve body and the second valve body, and described spheroid, valve rod are located on the first valve body, and described the first flange and the first valve body one are formed by connecting, and described the second flange and described the second valve body one are formed by connecting.
The upper end portion of described valve rod is provided with operating grip, and described valve rod is provided with step, is provided with the wear-resistant sleeve that rubber material is made between described step and handle.
The utlity model has following beneficial effect: the spool width of flow path of this ball valve is narrower, is the ellipse of upper and lower end flat transition, thereby effectively saves material, reduce production costs, and the flange of valve body is arranged to little tubaeform of outer imperial palace, make medium when circulation, improve flow velocity.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, valve body 1, valve seat 2, valve rod 3, spheroid 4, the first flange 5, the second flanges 6, through hole 7, operating grip 8, step 9, wear-resistant sleeve 10.
Embodiment
Below for accompanying drawing, embodiment of the present utility model is described further:
Shown in figure, a kind of indentation ball valve, comprise valve body 1, valve seat 2, valve rod 3 and spheroid 4, described spheroid 4 is positioned at valve body 1, and described valve rod 3 is connected with spheroid 4 through valve body 1, and described valve seat 2 is located between spheroid 4 and valve body 1, described spheroid 4 is oval, and the both ends of the surface of its passage are plane, the two ends of described valve body 1 are equipped with the first flange 5 and the second flange 6, and the through hole 7 of described the first flange 5 and the second flange 6 is the horn shape that outer imperial palace is little.According to such scheme, the spool width of flow path of this ball valve is narrower, is the ellipse of upper and lower end flat transition, thereby effectively saves material, reduce production costs, and the flange of valve body is arranged to little tubaeform of outer imperial palace, makes medium when circulation, improves flow velocity.
As shown in the figure, described valve body 1 is formed by connecting by the first valve body 11 and the second valve body 12, described spheroid 4, valve rod 3 are located on the first valve body 11, and described the first flange 5 and the first valve body 11 one are formed by connecting, and described the second flange 6 is formed by connecting with described the second valve body 12 one.Valve body adopts split type linkage structure, in use, is convenient to maintenance.
As shown in the figure, the upper end portion of described valve rod 3 is provided with operating grip 8, and described valve rod 3 is provided with step 9, is provided with the wear-resistant sleeve 10 that rubber material is made between described step 9 and handle 8.By between valve rod 3 and operating grip 8, being provided with wear-resistant sleeve 10, can effectively prevent that valve rod 3 is worn, guarantee working life.
Embodiment should not be considered as the restriction to model utility, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
