A valve with a dust-proof assembly

Abstract

The invention relates to the technical field of valves, specifically a valve with a dust-proof assembly, including a valve body, a connecting pipe, a filtering structure, a sewage discharge structure, a dust-proof structure, an indicating structure, a lubricating structure and a closing structure; The filter structure installed inside the body can play the role of filtering impurities, and with the setting of the sewage structure, the impurities intercepted on the filter structure can be discharged in time, and there is no need to replace the filter components inside the filter structure, and the cleaning is fast and convenient. Through the setting of the dust-proof structure, it not only avoids the accumulation of dust at the connection between the rotating parts and the valve body, which makes it difficult to rotate the transmission parts, but also brings convenience to the maintenance personnel, saving manpower and material resources to a certain extent, and the dust-proof structure While working, it can also act on the lubricating structure. Through the setting of the lubricating structure, the transmission parts inside the dust-proof structure can be lubricated with oil, thereby avoiding the situation that the transmission parts are stuck.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve with a dust-proof assembly. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-made valves, etc. according to the material. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from th...

AI Technical Summary

Problems solved by technology

[0003] In some areas where the working environment is relatively harsh, such as areas with large wind and sand, valves will be installed to control the on-off of the fluid, but the handwheel and valve body of the general valve are directly exposed to the outside air, and a large amount of sand will accumulate. In the rotating area between the hand wheel and the valve body, when the hand wheel needs to be turned, sand and dust will be screwed into the inside of the valve body, causing the hand wheel to be stuck, seriously affecting the use of the valve, and the valve is not oiled all the year round. There will be a stuck situation
