Abstract
The utility model discloses sealing structures on a kind of soft sealing butterfly valve, including valve body, it is characterized by: being rotatably equipped with valve rod in the valve body, axle sleeve is installed between the lower end and valve body of the valve rod, there is observation panel in the upper end of the valve body by flanged joint, weight is equipped in gap between the inner wall and valve rod of the flange, the lower end of the weight is equipped with V-type circle, and the bottom of the V-type circle is equipped with support ring.The utility model structure is simple, using firm stable, convenient for being sealed performance maintenance and sealing material replacement, good limit effect online in time.
Description
Technical field
The utility model relates to valve part field, sealing structure on specifically a kind of soft sealing butterfly valve.
Background technique
Valve is for being opened and closed pipeline, control flow direction, the parameter (temperature, pressure and flow) of regulation and control pumped (conveying) medium
Pipeline fittings.According to its function, shut-off valve, check-valves, regulating valve etc. can be divided into.Valve is the control in fluid delivery system
Component has the function of cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting or overflow pressure relief etc..For fluid control systems
Valve, various valves, kind and specification used in from simplest shut-off valve to extremely complex robot control system(RCS) are quite numerous
It is more.Valve can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium etc.
The flowing of various types fluid.Valve is also divided into cast iron valve, cast steel valve, stainless valve (201,304,316 according to material
Deng), chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
Utility model content
The utility model aim is there is provided a kind of structure is simple, using firm stable, convenient for being sealed online in time
Performance maintenance and sealing material are replaced, sealing structure on the soft sealing butterfly valve of good limit effect.
The utility model solves technical problem and provides following scheme:
Sealing structure on a kind of soft sealing butterfly valve, including valve body, it is characterised in that: be rotatably equipped with valve in the valve body
Bar is equipped with axle sleeve between the lower end and valve body of the valve rod, there is observation panel in the upper end of the valve body by flanged joint, described
Weight is equipped in gap between the inner wall and valve rod of flange, the lower end of the weight is equipped with V-type circle, the bottom of the V-type circle
Equipped with support ring.
The observation panel being connected with above the valve body upper flanges, the observation panel top are connected with electronic Worm gear mechanism.
The V-type circle that the utility model is arranged by weight and lower section, and it is equipped with support ring in the lower section of V-type circle, it is logical in this way
Crossing such combination may be implemented the sealing of valve rod, and can be when revealing, without in the case where removing electronic worm gear
Realize the maintenance of sealing performance and the replacement of sealing material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
