Abstract

The invention belongs to the technical field of protective devices for explosion-proof and leak-proof automatic closure of pressure gauges, and specifically relates to an explosion-proof and leak-proof protector for pressure gauges. The protector comprises a protector body, a conical hollow pipe and a one-way valve core. The conical hollow pipe is arranged in the protector body, and the one-way valve core is arranged in the conical hollow pipe. The one-way valve core contacts the exit conical surface of the conical hollow pipe under the action of pressure difference. The explosion-proof and leak-proof protector for pressure gauges of the invention has a simple structure, and implements automatic closure based on pressure difference and the principle of flow control. The loss of water, gas,oil and other liquid and gases after damage and failure of pressure gauges can be protected, and economic losses and safety accidents can be prevented.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof and leak-proof automatic closing protection devices for pressure gauges, and is suitable for explosion-proof and leak-proof protection of pressure gauges for measuring gas and liquid media in petroleum, chemical, chemical fiber, metallurgy, hydropower and other industrial sectors. 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...
