Pressure relief valve device for stirring station powder hopper

Abstract

The invention provides a pressure safe valve equipment for powder silo of mixing station with safety and reliability, accuracy reposition, simple structure, low cost, anti-corrosion and anti-rust, and easy maintenance, comprising balance weight cover, cylinder cover, connector and limiter. Said balance weight cover is connected with limiter by connector and is set on the cylinder body. The limiter is set under the cylinder body.

Description

technical field [0001] The invention relates to a pressure safety valve device, in particular to a pressure safety valve device for a powder material bin of a mixing station. Background technique [0002] During the use of the powder silo of the mixing station, in order to meet the safety requirements, a pressure safety valve device must be used. The function of the pressure safety valve of the powder bin of the mixing station is: when the pressure in the powder bin reaches the preset value, the pressure safety valve will open to release the excessive pressure in the powder bin to prevent damage to the powder bin. If the pressure safety valve cannot be opened under the set pressure or the set pressure is too high, the weak part of the top of the powder silo will be deformed and damaged due to the excessive pressure in the powder silo. At present, the powder silo of the mixing station usually uses a spring-type pressure safety valve device. The spring-type pressure safety va...

AI Technical Summary

Problems solved by technology

If the pressure safety valve cannot be opened under the set pressure or the set pressure is too high, it will cause deformation and damage to the weak part of the powder silo due to the excessive pressure in the powder silo

At present, the powder silo of the mixing station usually uses a spring-type pressure safety valve device. The spring-type pressure safety valve device has the following disadvantages: 1. Because the pressure safety valve is generally in an open environment, the moving parts such as springs are easy to rust, resulting in failure of the pressure safety valve. , so frequent inspection and maintenance are required

2. After the spring-type pressure safety valve has been operated once, it must be repaired and maintained in time, otherwise the cement and other powders trapped in the valve body will form hard lumps after absorbing moisture in the air, resulting in the pressure safety valve not being able to open or close tightly. , can not play its security role

3. The maintenance of the safety valve needs to be handled by climbing the ladder to the top of the powder warehouse about 15 meters above the ground, which is very troublesome
