Abstract
The utility model discloses an antistatic ball valve which comprises a valve body, a valve cover, a ball body, a valve rod and an operating mechanism. A flow cavity is arranged on the valve body, the ball body is arranged in the flow cavity, a valve seat is arranged in the valve body relatively to the two sides of the ball body, a valve rod sleeve which is matched with the valve rod and is communicated with an inner cavity of the valve body is arranged on the valve body, the valve rod penetrates through the valve rod sleeve, the inner end of the valve rod is matched with the ball body in a linkage manner after stretching into the valve body, the outer end of the valve rod is matched with the operating mechanism in a fixed connecting manner after stretching out of the valve rod sleeve, the valve rod is particularly a conductive valve body, the valve rod is particularly a conductive valve rod, and a sunken hole is arranged on the side wall at the inner end of the valve rod. A conductive spring and a conductive steel ball which are in mutual contact and matched with each other in a linkage manner are sequentially arranged in the sunken hole from inside to outside. As static electricity generated in the opening-closing process of the valve can be timely eliminated, the antistatic ball valve has the function of eliminating potential static safety hazards.
Description
Technical field
The utility model relates to a kind of ball valve, specifically is meant the antistatic ball valve that a kind of antistatic Security is good.
Background technique
Ball valve is a kind of valve of present extensive use, existing ball-valve structure generally comprises valve body, valve gap, spheroid and valve rod, operating device, valve body is provided with the stream chamber, spheroid places in the stream chamber, described valve body is provided with the valve stem casing of joining and being communicated with body cavity with valve stem casing, valve rod passes valve stem casing, and its inner is stretched in the valve body and is linked with spheroid, and its outer end is stretched out valve stem casing and is fixedly connected with operating device and cooperates.The ball valve of present this structure, its valve rod rotates in the process of controlling the spheroid keying by operating device, make spheroid and valve seat friction-produced static, and when being inflammable and explosive substances for the medium that transports, spheroid opens and closes the static that produces will bring potential safety hazard.
The model utility content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, the static that produces in the ball valve opening-closing process in time can be derived to prevent a kind of antistatic ball valve of accumulation of static electricity and provide a kind of.
For achieving the above object, the technical solution of the utility model is to include valve body, valve gap, spheroid, valve rod and operating device, valve body is provided with the stream chamber, spheroid places in the stream chamber, and the both sides with respect to spheroid in the described valve body are provided with valve seat, described valve body is provided with the valve stem casing of joining and being communicated with body cavity with valve stem casing, valve rod passes valve stem casing, its the inner is stretched in the valve body and with spheroid and is linked, its outer end is stretched out valve stem casing and is fixedly connected with operating device and cooperates, described valve body is the conduction valve body, described valve rod is the conduction valve rod, the sidewall of described valve rod the inner is provided with counterbore, is disposed with from inside to outside in this counterbore to be in contact with one another power spring and the conduction steel ball that is linked.By this setting, the static that the spheroid of ball valve produces with valve seat in opening and closing rotation process can be delivered on the valve rod by conduction steel ball and power spring, valve rod can export to static in the external environment by the position of handle or the contact of valve body upper valve rod then, prevent that static from accumulating in valve body, thereby eliminated accumulation of static electricity potential safety hazard, improved this security of products.
The sidewall that further setting is the relative valve stem casing of described valve rod position is provided with counterbore, is disposed with from inside to outside in this counterbore to be in contact with one another power spring and the conduction steel ball that is linked.By this setting, the static that is delivered on the valve rod from spheroid can be delivered on the valve stem casing of conduction valve body by power spring and conduction steel ball, thereby fast the static in the valve body is derived, and prevents accumulation of static electricity in the valve body.
Further being provided with is that described valve stem casing madial wall is provided with packing cavity, and described valve bonnet seal is fixed on the upper end of packing cavity, and described packing cavity is provided with " V " shape filler.This setting, and the past both sides expansion after being compressed of " V " shape filler, thus seepage prevented, improved the sealing of the valve rod of ball valve.
Further being provided with is that described valve rod operating device is a handle.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
