Abstract
The utility model relates to a butterfly valve, particularly a corrosion resistant butterfly valve used for the conveying pipe network of strong acid, alkalis and other corrosive media, which comprises a valve body, a valve seat, a valve plate positioned in the valve body and a valve rod combined together with the valve plate, wherein, the valve seat is composed of a base material made from a rubber material and a corrosion resistant layer made from a teflon material. The valve plate made from a plastic material is connected together with the valve rod by a prism-shaped connecting hole. The production cost is obviously lower than the butterfly valve in the same class made from a stainless steel material, but the performance of strong acid, strong alkali and other corrosive media is obviously better than the butterfly valve in the same class made from the stainless steel material.
Description
The utility model relates to a kind of butterfly valve, particularly a kind of corrosion resistance butterfly pump that can be used in the Korrosionsmedium transmission pipeline networks such as strong acid, alkali.
Mostly the butterfly valve that is widely used at present in the Korrosionsmedium transmission pipeline networks such as strong acid, alkali is to adopt stainless steel material to be made.Though above-mentioned this product has good antiseptic property, its cost of production is really obviously higher.
The purpose of this utility model is exactly in order to provide a kind of cost of production low, but really has good anti-strong acid, alkaline corrosion resistance butterfly pump.
The purpose of this utility model can adopt following measure to realize:
Corrosion resistance butterfly pump of the present utility model is by valve body, valve seat, is positioned at the valve plate of valve body and the valve rod composition that combines with valve plate; Its valve seat is formed by the base material that is made with rubber material with by the anticorrosive coat that the polytetrafluoroethylene material forms; Its valve plate is to adopt plastic materials to be made, and valve plate combines by prismatic attachment hole and valve rod.
Attachment hole in the utility model on the valve plate is the hexagon attachment hole, and the bottom of the valve rod that is mated is the hexagonal prism structure; Its attachment hole can be the profile of tooth attachment hole also, and the lower shape of the valve rod that is mated also correspondingly is made into the cylinder that matches with the hole shape of attachment hole.
For reaching the anti-corrosive properties that both can improve valve plate, increase its cost of production again not manyly, also available polytetrafluoroethylene material becomes clad, and it is wrapped in the top layer of valve plate.
Advantage of the present utility model is: though its cost of production is starkly lower than the similar dish valve that is made with stainless steel material, the performance of Korrosionsmediums such as its anti-strong acid, highly basic really obviously is better than the similar butterfly valve that is made with stainless steel material.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B 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, corrosion resistance butterfly pump of the present utility model is by valve body (1), valve seat (3), valve rod (2) composition that is positioned at the valve plate (5) of valve body and combines with valve plate; Its valve seat is made up of base material that is made with rubber material (3) and the anticorrosive coat (4) that formed by the polytetrafluoroethylene material; Its valve plate (5) is to adopt plastic materials to be made, and the attachment hole on the valve plate is (7) hexagon attachment hole, and the valve rod that is mated (2) bottom also is the hexagonal prism structure, and both combine by friction tight Placement; For reaching the anti-corrosive properties that both can improve valve plate, increase the purpose of its cost of production again not manyly, the structure of valve plate is to adopt the polytetrafluoroethylene material is become clad (6) in the present embodiment, and it is wrapped in the top layer of the valve plate matrix (5) that forms with the common engineering plastic production.
The valve plate in the utility model and the combination of valve rod why change traditional taper pin fixedly the Placement of valve plate and valve rod for adopting the friction tight Placement in prismatic hole, its purpose is exactly in order to prevent that corrosive liquid from infiltrating in the attachment hole of valve plate by taper pin-hole, thus the corrosion valve rod.
Claims (3)
1, a kind of corrosion resistance butterfly pump, it comprises valve body (1), valve seat (3), be positioned at the valve plate (5) of valve body and the valve rod (2) that combines with valve plate, it is characterized in that: valve seat is made up of the base material (3) of rubber material making and the anticorrosive coat (4) that is formed by the polytetrafluoroethylene material; The valve plate (5) that is made by plastic materials combines by prismatic attachment hole (7) and valve rod (2).
2, corrosion resistance butterfly pump according to claim 1 is characterized in that: the attachment hole (7) on the valve plate (5) is the hexagon attachment hole, and the bottom of the valve rod that is mated (2) is the hexagonal prism structure.
