Abstract

The invention relates to an explosion-proof and leak-proof speed breaker for pressure gauges, comprising a speed breaker body. The speed breaker body includes an outlet end suitable for being connected with a pressure gauge, an inlet end suitable for being connected with a pressure switch, a conical hollow pipe located in the cavity of the speed breaker and vertically communicated with the inlet end and the outlet end, and a bypass pipe of which the water inlet is communicated with the water inlet of the conical hollow pipe and the water outlet is communicated with the water outlet of the conical hollow pipe, wherein the conical hollow pipe is configured with a flow regulating screw and a one-way valve core in turn in the direction from the large-diameter water inlet to the small-diameterwater outlet, the flow regulating screw is fixedly connected with the inner wall of the inlet end, the one-way valve core is suitable for moving along the axis to the water outlet in the conical hollow pipe, and a pressure regulating valve assembly is arranged at the water inlet of the bypass pipe.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to an explosion-proof and leak-proof speed breaker for pressure gauges. Background technique [0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. The types of pressure gauges include ordinary and special pressure gauges, which are damaged by long-term corrosion of liquid and gas media, high pressure and strong vibration during use, and cannot be automatically closed in time, making the liquid and gas media Leakage causes damage to the environment, equipment and property, and poses safety hazards to harmful and flammable gas leakage. [0003] Therefore, how to solve the technical problem of automatic shutdown of the pressure gauge after failure and damage often leads to the loss of ...
