Material distributing valve externally provided with sealing pieces and replacing method of sealing pieces of material distributing valve

Abstract

The invention relates to the technical field of material distributing valves, in particular to a material distributing valve externally provided with sealing pieces and a replacing method of the sealing pieces of the material distributing valve. The material distributing valve comprises a valve body, a valve plate, the sealing pieces and pressing plates. Long holes are formed in the valve body andcorrespond to the positions, for closing the two sides of discharging ports, of the valve plate, the sealing pieces comprise embedded strips and buffer plates, and the embedded strips are arranged inthe long holes and protrude inwards relative to the inner wall of the valve body, so that the gap between the side of the valve plate and the inner wall of the valve body is closed. The pressing plates are in locking connection with the valve body, so that the buffer plates of the sealing pieces are pressed between the pressing plates and the outer wall face of the valve body. Through the externally-arranged sealing pieces, the difficulty of replacing the sealing pieces is greatly reduced, the replacement speed is high, and normal work of equipment is prevented from being influenced. The pressing plates and bearing seats are arranged on the outer portion of the valve body, so that parts in the valve body are few, and the problem of material accumulation is avoided. The sealing pieces areformed by the embedded strips and the buffer plates which are integrally formed, connectivity between the embedded strips and the buffer plates is high, damage is not prone to occurring, and service life is long.

Description

technical field [0001] The invention relates to the technical field of material distribution valves, in particular to a material distribution valve with external seals and a method for replacing the material distribution valve seals. Background technique [0002] With the continuous improvement of project quality, environmental protection requirements and civilized construction requirements, the shortcomings and limitations of mortar mixing on the construction site have become more and more prominent, and dry-mixed mortar has been more and more popular due to its advantages in technical performance and social benefits. people's favor. [0003] At present, there are many types of dry-mixed mortar products. Considering factors such as equipment costs, most dry-mixed mortar manufacturers use the same mixer to produce different types of dry-mixed mortars by adjusting the production formula. In the transportation of formulas and finished products, the existing conveying equipmen...

AI Technical Summary

Problems solved by technology

In the transportation of formulas and finished products, the existing conveying equipment controls the conveying direction of materials by the distribution valve. The distribution valve changes the discharge direction through the reversible valve plate mechanism. The valve installs a sealing strip made of flexible material such as rubber on the edge of the valve plate or the corresponding position inside the valve body. Therefore, it is necessary to set up a corresponding structure such as a mounting bracket to connect the sealing strip to the valve plate or the inner wall of the valve body. Since the sealing strip is a vulnerable part , it needs to be replaced regularly, but it is difficult to replace the sealing strip inside the distribution valve, and it takes a lot of time to replace each time, which affects the production process; at the same time, the installation bracket and other structures will form a dead space in the distribution valve. As a result, there will be a material accumulation problem in the material distribution valve, which will also affect the normal production work to a certain extent.
