Abstract
The utility model discloses a main seal assembly of soft seal butterfly valve, including the valve body, its characterized in that: the valve body internal rotation is installed the valve rod, the lower extreme of valve rod is connected with the valve clack, the upper end of valve clack is connected through the valve clack nut and is realized the upper and lower slip of valve clack, be equipped with the soft sealing layer on the lateral wall of valve clack. The utility model discloses simple structure reduces the sealed moment of torsion of valve, and it is firm stable to use, and is spacing effectual.
Description
Technical Field
The utility model relates to a valve part field specifically is a main seal assembly of soft seal butterfly valve.
Background
Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like. The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are further classified into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, etc. according to the material.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure reduces the sealed moment of torsion of valve, uses firmly stably, the main seal assembly of spacing effectual soft seal butterfly valve.
The utility model provides a technical problem provide following scheme:
the utility model provides a main seal assembly of soft seal butterfly valve, includes the valve body, its characterized in that: the valve comprises a valve body and is characterized in that a valve rod is rotatably mounted in the valve body, a valve clack is connected to the lower end of the valve rod, the upper end of the valve clack is connected through a valve clack nut to realize the up-and-down sliding of the valve clack, a soft sealing layer is arranged on the side wall of the valve clack, a main sealing surface is arranged at the upper end of the soft sealing layer, a protruding block is arranged on the main sealing surface, and slope surfaces with different angles.
The inclination angle of the lower slope surface is larger than that of the upper slope surface.
The utility model discloses install the valve rod at the valve body internal rotation, be connected with the valve clack at the lower extreme of valve rod, connect the upper and lower slip that realizes the valve clack through the valve clack nut in the upper end of valve clack, and be equipped with the soft sealing layer on the lateral wall of valve clack, the upper end of soft sealing layer is equipped with the main seal face, and the angle of two upper and lower slopes of the main seal face is different, because slope angle is little down, the resistance of reciprocating of valve clack is little like this, and the moment of torsion that needs simultaneously.
