Explosion-proof Valve Silica Sol Investment Casting

Product Introduction

Explosion-proof valves are used in dust removal systems containing flammable gases or substances and can be used as pressure relief devices for explosive pipelines or equipment. The diaphragm of the explosion-proof valve is usually calculated according to the operating pressure of the dust removal system and the content of combustible substances, and then the material, thickness, and scratches are selected, and the normal operation of the system must not be affected by improper selection.

Explosion-proof valves generally come in two forms, horizontal explosion-proof valves and vertical explosion-proof valves. These two explosion-proof valves adopt the structure of an explosion-proof membrane and cover. The vertical explosion-proof valve is installed on the cylinder, while the horizontal explosion-proof valve is installed on the top. Explosion-proof valve silica sol investment casting is mainly used in large-scale mechanical stages, lifts, lifts, vehicle inspection and maintenance beams, and other equipment hydraulic systems without mechanical locking systems, mainly for protection and to prevent safety accidents. It belongs to the locking measure of the hydraulic system. This requirement is a necessary requirement in CE certification, so the explosion-proof valve was first invented and produced in Europe. Later, it was spread to China and has been widely used. The explosion-proof valve has a simple structure and a compact shape and can be easily connected to the entrance of the execution unit.

The working principle of the explosion-proof valve

There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity and two electromagnets on both sides. Which side of the magnet coil is powered The valve body will be attracted to which side, by controlling the movement of the valve body to block or leak different oil discharge holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then pass through the oil discharge pipe. The pressure is used to push the oily piston, the piston drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the electric current of the electromagnet.

Working conditions

1. Pressure range: -10kPa~+20kPa

2. Temperature range: -20℃~395℃

Installation site

Explosion-proof valve silica sol investment casting is prone to implosion on the boiler body and the front flue of the dust collector.

Installation requirements

1. The installation of the explosion-proof valve can be installed at any angle.

2. The minimum distance between the installation positions of two explosion-proof valves is 200mm.
