Abstract

The utility model discloses a hard-seal butterfly valve adopting male and female face arc transition. The hard-seal butterfly valve adopting the male and female face arc transition comprises a valve body and a valve rod, wherein a fluid inlet and a fluid outlet are arranged on two sides of the valve body; a butterfly plate is fixedly arranged on the valve rod; the butterfly plate is positioned in the valve body and is matched with a sealing valve seat in the valve body; the sealing valve seat is fixedly arranged on the inner wall of the valve body; a groove is formed on the annular sealing surface of the sealing surface of the sealing valve seat and the butterfly plate; a projection is formed on the annular sealing surface of the sealing surface of the butterfly plate and the sealing valve seat; the groove is matched with the projection; and the annular sealing surfaces of the sealing valve seat and the butterfly plate are made of high-temperature-resistant hard-seal materials respectively. The hard-seal butterfly valve adopting the male and female face arc transition has a simple structure, is convenient to assemble and use, adopts the hard-seal materials and has high wear resistance. The annular sealing surfaces of two sides of the groove and the projection adopt arc transition, so the hard-seal butterfly valve is convenient to manufacture and use, reduces the rejection rate and improves the working efficiency.

Description

A kind of hard seal butterfly valve of male and fomale(M&F) arc transition
Technical field
The utility model relates generally to a kind of hard seal valve, relates in particular to a kind of hard seal butterfly valve of male and fomale(M&F) arc transition.
Background technique
The valve seal seat place plane of rotation of existing butterfly valve adopts simple sealing configuration at the valve flowing channel place, reliably will increase the contact static pressure of sealing surface for making sealing as far as possible, in use be through on the butterfly plate sealing surface, install additional can elastic compression soft sealing materials such as rubber realize; Such sealing is because of its serious wear, and it is big that valve opens and closes moment, again because the soft sealing material resistance to high temperature is poor; Big limitations its using scope; If adopt resistant to elevated temperatures hard sealing, and existing structure is very difficult in the manufacturing, is not easy when cooperating with valve seat; Reject rate is high, and manufacturing efficiency is low.
The model utility content
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of hard seal butterfly valve of male and fomale(M&F) arc transition is provided, and it is poor to have solved the soft sealing material resistance to high temperature, big limitations its using scope; The resistant to elevated temperatures very difficulty that is sealed in firmly in the manufacturing; Be not easy problem such as reject rate is high, and manufacturing efficiency is low when cooperating with valve seat.
The utility model is realized through following technological scheme:
A kind of hard seal butterfly valve of male and fomale(M&F) arc transition includes valve body and valve rod, and the both sides of said valve body are respectively equipped with inflow port, go out head piece; Be installed with butterfly plate on the said valve rod; Said butterfly plate is positioned at valve body, and cooperatively interacts with seal valve seat in the valve body, and said seal valve seat is fixedly installed on the valve interior wall; The annular sealing surface at the sealing surface place of said seal valve seat and butterfly plate is provided with groove; The annular sealing surface at the sealing surface place of said butterfly plate and seal valve seat is provided with convexity, and said groove and convexity cooperatively interact, and the annular sealing surface of seal valve seat and butterfly plate adopts resistant to elevated temperatures hard sealing material to process respectively.
The hard seal butterfly valve of described male and fomale(M&F) arc transition is characterized in that: the annular sealing surface of described groove and protruding both sides all adopts arc-shaped transition.
Its working principle is: through cooperating of the groove on the sealing surface of seat and butterfly plate sealing surface raising; Its good seal performance, sealing surface adopt hard sealing material, and wearability is good; And the annular sealing surface of groove and protruding both sides all adopts arc-shaped transition; Manufacturing and easy to use has reduced reject rate, has improved working efficiency.
The advantage of the utility model is following:
The utility model is simple in structure, easy to install, adopts hard sealing material, and wearability is good, and the annular sealing surface of groove and protruding both sides all adopts arc-shaped transition, makes and easy to use, has reduced reject rate, has improved working efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of hard seal butterfly valve of male and fomale(M&F) arc transition includes valve body 1 and valve rod 2; The both sides of valve body 1 are respectively equipped with inflow port, go out head piece, are installed with butterfly plate 3 on the valve rod 2, and butterfly plate 3 is positioned at valve body 1; And cooperatively interact with the seal valve seat 4 in the valve body 1; Seal valve seat 4 is fixedly installed on valve body 1 inwall, and seal valve seat 4 is provided with groove 5 with the annular sealing surface at the sealing surface place of butterfly plate 3, and butterfly plate 3 is provided with protruding 6 with the annular sealing surface at the sealing surface place of seal valve seat 4; Groove 5 cooperatively interacts with protruding 6, and the annular sealing surface of seal valve seat 4 and butterfly plate 3 adopts resistant to elevated temperatures hard sealing material to process respectively; The annular sealing surface of described groove 5 and protruding 6 both sides all adopts arc-shaped transition.
