understanding the explosion-proof electric pinch valve： features and applications
Release time:2026-01-21 14:55:34
The explosion-proof electric pinch valve is a specialized device designed to control the flow of various fluids, particularly in environments where the risk of fire or explosion is prevalent. This type of valve is essential in many industries, including oil and gas, chemical manufacturing, pharmaceuticals, and food processing, where handling potentially hazardous materials is routine. This article will delve into the structure, working principles, advantages, applications, and maintenance of explosion-proof electric pinch valves.
Structure and Components
At its core, the explosion-proof electric pinch valve consists of several critical components：
Body and Housing： The valve body, typically constructed from materials such as cast iron, carbon steel, or stainless steel, achieves the necessary strength to withstand high pressure and temperature conditions. The outer casing is designed to meet specific explosion-proof standards, ensuring safety in volatile environments.
Pinch Sleeve： The pinch sleeve, the crucial component of the valve, is made of flexible materials like rubber, silicone, or polyurethane. This sleeve is compressed or released to either block or allow the flow of the fluid, making the pinch valve particularly effective with slurries, pastes, and corrosive substances.
