Description
Technical Field
The utility model belongs to the valve field, especially a ball valve of safe pressure release.
Background
The valve is widely applied to the fields of petroleum, petrochemical oil transportation and gas transportation pipelines, and safety accidents such as valve damage, even leakage and the like can be caused by overlarge pressure of a pipeline in an environment with large temperature change. Ball valves used in these situations are generally provided with structures, and in order to prevent leakage of the pressure relief holes, the pressure relief holes are generally sealed by bolts in the ordinary environment, and pressure relief is needed to enable the bolts to be manually removed for pressure relief operation. However, if the pressure in the valve is too high, the bolt can be sprayed and fly out, even personnel can be injured, and certain potential safety hazard exists.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a design science, simple structure, be convenient for operation, the ball valve of the safe pressure release of raising the efficiency.
The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides a ball valve of safe pressure release which characterized in that: the ball valve comprises a valve body, a pressure relief hole, a plugging bolt and a protective cover, wherein the middle part of one side of the valve body is provided with the pressure relief hole, the inside of the pressure relief hole is connected with the pressure relief hole of a ball core, and the end part of the pressure relief hole is provided with an internal thread; a plugging bolt is engaged and installed in the pressure relief hole; a protective cover is fixedly arranged on the valve body for the pair of pressure relief holes, the protective cover is of a cross structure, a through hole is formed in the center of the top end of the protective cover, the diameter of the through hole is smaller than that of a top cap of the plugging bolt, and the plugging bolt is prevented from flying out but can be passed through by a bolt adjusting tool; the side clearance of protection casing is less than the shutoff bolt and prevents that the shutoff bolt from breaking away from the protection casing and causing and lose.
The protective cover structure comprises protective plates, folding legs and folding feet, wherein the centers of the protective plates crossed in the middle are provided with through holes, the four edges of the protective plates are respectively provided with the folding legs facing the valve body, the height of the folding legs is greater than the length of the plugging bolts, and gaps among the folding legs are smaller than the diameter of the plugging bolts; the bottom of the folding leg is provided with a folding leg which is fixed on the outer wall of the valve body by adopting a screw.
The plugging bolt comprises a nail cap, a screw rod, a convex shoulder and a radial through groove, wherein the screw rod is coaxially arranged at the lower end of the nail cap, and four inclined teeth are uniformly distributed on the screw rod; a convex shoulder with the diameter larger than that of the top cap is arranged between the top cap and the screw rod; the top of the screw cap of the plugging bolt is provided with a radial through groove.
The utility model has the advantages that:
the utility model discloses simple structure, the practicality is strong, installs crossing protection casing outside the shutoff bolt, effectively blocks the bolt departure to the bolt can not break away from the protection casing, prevents that the shutoff bolt from losing.
