Abstract
The utility model discloses a ball valve which comprises a valve body, a sphere, a valve rod and a handle, wherein the sphere is arranged in the valve body and used for controlling the communication of passages of the valve body; a mounting hole used for mounting the valve rod is formed in the valve body; one end of the valve rod penetrates through the mounting hole and is linked with the sphere, and the other end thereof is connected with the handle; a positioning nut is arranged on the outer side of one port of the valve body, and a valve cover is arranged on the inner side of the other port of the valve body; a first seal assembly is arranged between the sphere and the valve body; a second seal assembly is arranged between the valve rod and the valve body. The ball valve has a simple structure and is easy to implement; if a medium flowing through the ball valve leaks, the embedded design of the valve cover prevents the flowing medium from leaking to outside; in addition, the positioning nut is added, so that the handle can be placed in a position according to the actual demand, the operation of constructors is facilitated, and more convenience is brought to later utilization.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of ball valve.
Background technique
Ball valve is a kind of valve that drives spherical valve core and rotate around the axis of valve rod by valve rod.Be mainly used in blocking or connect the medium in pipeline, be widely used in every profession and trade.Ball valve is when being connected with pipeline, and the position of selection handle that can't be autonomous, can cause the inconvenience of follow-up use.In addition, the valve gap of general ball valve all arranges and the valve body outside, and the medium circulated by ball valve easily is leaked to the valve body outside.
The model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of compact structure, ball valve easy and simple to handle.
To achieve these goals, the utility model can be taked following technical proposals: a kind of ball valve comprises valve body, is arranged in valve body and controls spheroid, valve rod, the handle that valve channel is communicated with, described valve body is provided with the mounting hole of installing for described valve rod, described valve rod one end links through mounting hole and described spheroid, the valve rod the other end is connected with handle, the described valve body one port outside is provided with setscrew nut, the inboard, another port is provided with valve gap, be provided with the first black box between described spheroid and valve body, be provided with the second black box between described valve rod and valve body.
As preferably, described the first black box is phenyl tetrafluoride pad.
As preferably, the second black box is O type circle.
As preferably, the quantity of described O type circle is two.
As preferably, the port of described valve gap and valve body is threaded connection.
The beneficial effects of the utility model are: simple in structure, be easy to realize, if flow through, the medium of ball valve leaks, the design of embedded valve gap has prevented that the dielectric leakage of circulation is to outside, increased in addition setscrew nut, that just can place the position of handle according to actual needs always, has facilitated workmen's operation also to the use in later stage, to bring many facilities.
For above-mentioned and other objects, features and advantages of the present utility model can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, be described in detail below.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The A that Fig. 2 is Fig. 1 is to sectional view.
Embodiment
Mode of execution of the present utility model is described with reference to the accompanying drawings.A kind of ball valve comprises valve body 1, is arranged at spheroid 2, valve rod 3, handle 4 that the interior control valve channel of valve body 1 is communicated with, offer the mounting hole of installing for valve rod 3 on valve body 1, valve rod 3 one ends are connected with spheroid 2 through mounting hole, for rotating sphere 2, realize described spheroid 2 the runner hole open or closed, valve rod 3 the other ends are connected with handle 4 by screw 9, by handle 4 rotating sphere more effortlessly.The valve body 1 one port outsides are arranged with a location nut 5, at ball valve with during other pipe fitting is connected, can come the position of position fixing handle 4 by regulating setscrew nut 5, the another port installed inside of valve body 1 has a valve gap 6, and valve gap 6 is threaded connection with the port of valve body 1.Be provided with the first black box 7 between spheroid 2 and valve body 1, in the present embodiment, the first black box 7 is preferably phenyl tetrafluoride pad; Be provided with the second black box 8 between valve rod 4 and valve body 1, in the present embodiment, the second black box 8 is preferably O type circle, and the quantity of O type circle can be two.
