Abstract
The utility model discloses a safe explosion protection ball valve, which comprises a left valve body and a right valve body. The left valve body and the right valve body are connected into a whole through bolts, a blow-out preventer is mounted on the left valve body, a ball is arranged inside the right valve body, a through hole is formed inside the ball, a valve stem is connected with the upper end of the ball and is extended out of an opening on the right valve body, the space between the opening on the right valve body and the valve stem is filled with packing, the upper end of the valve stem is sleeved with a packing gland which is screwedly connected with the inner wall of the opening, and the packing gland presses on the packing . Because of the arrangement of the blow-out preventer, a delivery pipe does not explode even in high pressure conditions. The safe explosion protection ball valve takes protection effect, and effectively prevents the occurrence of accidents.
Description
Technical field
The utility model belongs to a kind of valve, specifically is a kind of safety anti-explosive ball valve.
Background technique
Ball valve is to make open-shut device with the spheroid that has circular channel, and spheroid rotates the valve of realizing switching motion with valve rod.The open-shut device of ball valve is a porose spheroid, winds the axis rotation perpendicular to passage, thereby reaches the purpose that opens and closes passage.Ball valve mainly supplies the usefulness of opening and closing pipeline and equipment medium.But in use, tend to running into line clogging or other reason causes hydrodynamic pressure to raise suddenly, when surpassing the valve maximum set value, cause pipe explosion, cause the generation of serious accident, not only can make people's property obtain loss, even can have influence on people's life safety.
The model utility content
The purpose of this utility model provides a kind of safety anti-explosive ball valve, can be under the situation of burst high pressure, and pressure release voluntarily prevents the conveyance conduit blast, plays the safety protection effect, effective trouble-saving generation.
The technical solution of the utility model is as follows:
The safety anti-explosive ball valve, include left and right valve body, described left and right valve body links into an integrated entity by bolt, and spheroid is arranged in the right valve barrel, in the described spheroid through hole is arranged, the spheroid upper end is connected with valve rod, described valve rod stretches out outside the perforate on the right valve barrel, is filled with filler between perforate on the described right valve barrel and the valve rod, and described valve rod upper end is with Gland, described Gland and described perforate inwall screw togather, and described Gland is pressed in described filler; It is characterized in that on the described left valve barrel sidewall perforate being arranged, screw-thread fit has cylindrical shell on the inwall of perforate, the cylindrical shell lower end has vertical suction port and communicates with body cavity, the cylindrical shell upper end is opened wide, the cylinder inboard wall of the suction port top of cylindrical shell has the step section, the last inside edge jacking of step section has cone, have pressure relief opening on the sidewall of the overhead cylinder of step section, the upper end of cone is connected with spring, the upper end of spring is connected with the compact heap that is slidingly matched with cylinder inboard wall, the outer side wall scyewed joint has friction top on the cylindrical shell, and spring holds out against compact heap on the lower end surface of friction top.
Compared with prior art; the utility model is running into line clogging or is causing valve closing owing to misoperation and other determines that liquid or the gas pressure of factor in causing managing raises suddenly; when surpassing the maximum set pressure of valve; liquid or gas will be realized pressure release with valve pocket and pressure relief opening conducting by explosion-proof device; thereby play protective action to conveyance conduit; take precautions against the generation of pipe explosion serious accident effectively, safeguarded the safety of people's lives and properties.
