Abstract
The utility model discloses a safe explosion-proof stop valve comprising a valve body, wherein, an inflow port and an outflow port are formed on the left and the right sides of the valve body respectively, a stop port is formed in the valve body, a valve cap is installed on the valve body, a valve rod is installed in a rotating manner in the valve cap, a rotatable valve clack is connected to the lower end of the valve rod, the valve clack is engaged with the stop port, the upper section of the valve rod is in threaded connection with the valve cap, a sealing filler is arranged between the lower section of the valve rod and the valve cap, a packing gland which is in screw fit with the exterior of the valve rod is pressed at the upper end of the filler, and an explosion-proof device is installed on the housing on one side of the inflow port. Due to the use of the explosion-proof device, the utility model can protect the delivery pipe against implosion under high-pressure conditions, achieves the function of safety protection, and effectively prevents accidents.
Description
Technical field
The utility model belongs to a kind of valve, specifically is a kind of safety anti-explosive stop valve.
Background technique
Stop valve is the valve that closure member (flap) moves along the valve seat center line.According to this mobile form of flap, the variation of valve seat port is and the stroke of flap relation in direct ratio.Because the valve rod of this type of valve is opened or shutoff stroke is shorter relatively, and have and cut off function very reliably,, be fit to very much and the adjusting of flow again because the variation of valve seat port and the stroke relation in direct ratio of flap.Therefore, such valve is suitable as cut-out or adjusting and throttling usefulness very much.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 stop 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 stop valve, include valve body, described valve body and arranged on left and right sides has inflow port respectively, goes out head piece, have in the described valve body by mouth, on the described valve body valve gap is installed, be rotatablely equipped with valve rod in the described valve gap, described valve rod lower end is connected with rotating flap, described flap with by mouthful cooperating; By being threaded, be provided with stuffing box packing between valve rod hypomere and the valve gap between described valve rod epimere and the valve gap, valve rod has screwed togather Gland outward and has been pressed in the filler upper end; On the housing of described inflow port one side explosion-proof device is installed.
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.
