Abstract
The utility model relates to a sealing valve seat used for a spherical butterfly valve, which is characterized in that the sealing valve seat of the utility model is composed of a sealing valve seat and elastic fillers, wherein the sealing valve seat is made of materials with wire resistance, high temperature resistance and corrosion resistance, and the section of the sealing valve seat forms a ball-head rod shape; the elastic fillers are filled in an inner cavity of the sealing valve seat.
Description
The utility model relates to a kind of seal arrangement, relates to a kind of seal valve seat that is applicable to spherical butterfly valve specifically.
The seal valve seat of the spherical butterfly valve of public use at present mostly is and adopts polytetrafluoroethylmaterial material to make.Because above-mentioned material is difficult for making baroque seal ring, this has brought many restrictions with regard to the use of giving manufactured good, and is relatively poor because of its rebound elasticity in addition, has also just reduced its sealability and working life naturally.
The novel purpose of this use provides a kind of scientific and reasonable for structure with regard to being to overcome above-mentioned the deficiencies in the prior art part, and favorable sealing property is changed the seal valve seat that is applicable to spherical butterfly valve easily.
The purpose of this utility model can adopt following measure to realize:
Seal valve seat of the present utility model is that the seal valve seat of bulb clavate and the elastic filling substance that is filled in its inner chamber are formed by the cross section wear-resisting, high temperature resistant, that resistant material is made.
Advantage of the present utility model is that sealing is reliable, long service life.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
As shown in the figure, the seal valve seat of the present utility model cross section of being made by full fluorine copolymer (ethylene-propylene) material is that the seal valve seat (1) of bulb clavate and the filler of being made by rubber material (2) that are filled in its inner chamber are formed.
Claims (1)
1, a kind of seal valve seat that is applicable to spherical butterfly valve is characterized in that: described seal valve seat is that the seal valve seat (1) of bulb clavate and the elastic filling substance (2) that is filled in its inner chamber are formed by the cross section wear-resisting, high temperature resistant, that resistant material is made.
