Gate sealing valve

Abstract

The invention relates to a gate sealing valve, comprising a housing, a feed pipe, a sealing part, a stock stop part, a sealing driving part, a stock stop driving part, wherein the feed pipe is inserted into the housing; a discharge hole is arranged on the housing; both the sealing driving part and the stock stop driving part are hermetically arranged on the housing; both the sealing part and the stock stop part are arranged in the housing; the stock stop driving part is connected with the stock stop part and used for driving the stock stop part to cut off or communicate with a passage located between the feed pipe and the discharge hole; the sealing part can be slidingly and hermetically sheathed on the outer wall of the feed pipe; the sealing driving part is connected with the sealing part and used for driving the sealing part to hermetically or non-hermetically contact with the stock stop part; preferably, the sealing part comprises a packing holder, a first sealing ring, and a second sealing ring; and the stock stop part is a drawer board. The gate sealing valve shortens the production cycle, and has the advantages of: unique and clever design, strong applicability, difficult stock stopping, concise structure, simple manufacture, low cost, and suitability for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to the technical field of conveying valves, in particular to a gate sealing valve. Background technique [0002] At present, in the rubber and plastic auxiliary machinery industry, the most automatic conveying methods are suction and pressure conveying, which can be divided into quantitative conveying and non-quantitative conveying according to the conveying amount. At present, the common ways of quantitative transportation are: rotary valve, ball valve, butterfly valve, knife gate valve, two-way supplementary air transportation, etc. [0003] All kinds of professional valves are purchased from specialized manufacturers, and all have different disadvantages. The rotary valve is greatly affected by the state of the conveying raw materials (transportation volume, temperature, etc.), there must be a certain gap between the valve and the valve body, and the price is relative...

AI Technical Summary

Problems solved by technology

The rotary valve is greatly affected by the state of the conveying raw materials (transportation volume, temperature, etc.), there must be a certain gap between the valve and the valve body, and the price is relatively expensive; Not suitable (easy to trap material), mainly rely on imports at present; butterfly valve is easy to trap material and is rarely used; there must also be a certain gap between the valve and the valve body of the knife gate valve, and it is also easy to trap material and takes up a lot of space; The above types of valve bodies all adopt casting structure to reduce weight

The cleaning of raw materials conveyed by the two-way supplementary air is not thorough, and the quantitative accuracy is poor
