Description
Technical Field
The utility model relates to valve technical field, an eccentric butterfly valve and disk seat thereof specifically says so.
Background
The valve is ubiquitous in people's life, and little to domestic tap, the water supply pipe network in big to the city, no one leaves the valve, along with industrial development and demand, has had higher and higher requirements to the sealing performance of valve, must guarantee the safe and reliable use of valve simultaneously. Common soft seal valves are all in friction extrusion of metal and soft seal materials, so that the soft seal materials are in interference fit to achieve a sealing effect, but due to repeated friction of the soft seal materials and the metal, the soft seal materials are abraded, the sealing failure of the valves is caused, the service life is shortened, loss is caused, and even major accidents are caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an eccentric butterfly valve and disk seat thereof has solved the disk seat because long-term wearing and tearing of opening and close lead to leaking, the life of valve is short, the problem that valve sealing performance is low.
In order to achieve the above object, the present invention provides the following technical solutions: the utility model provides an eccentric butterfly valve and disk seat thereof, which comprises a valve body, the butterfly plate, the valve rod, special-shaped sealing washer, the sealing washer locating plate, valve rod bearing, the valve rod filler, valve rod seal locking device, etc., be equipped with valve rod bearing in the upper and lower shaft hole of valve body, the butterfly plate is installed in the valve body latus rectum, the valve rod passes the valve rod bearing in shaft hole on the valve body, pass the shaft hole of butterfly plate simultaneously, at last with the valve rod bearing cooperation in shaft hole under the valve body, the butterfly plate becomes a whole through the pin junction with the valve rod, be equipped with the special-shaped sealing washer with butterfly plate matched with in the valve body, special-shaped sealing washer passes through special-shaped sealing washer and bolt fastening on the valve body, become a whole, be equipped with seal gasket between valve body and the sealing washer locating plate, the upper shaft hole department of valve body is equipped with sealing material filling department, inside is equipped with the valve rod filler, valve rod seal locking device compresses tightly the valve rod filler through the bolt.
Preferably, the special-shaped sealing ring is composed of two parts, wherein the outer part is a circular ring-shaped soft sealing material sheet, the inner part is a cylindrical ring, and the cylindrical ring is covered by the soft sealing material sheet.
The utility model has the advantages that: the structure is simple, and parts are convenient to machine; when the sealing valve seat special-shaped sealing ring and the butterfly plate made of the double-sealing material are in contact, the special-shaped sealing ring is extruded and sealed due to the special structure of the special-shaped sealing ring, the service life of the valve can be prolonged, and the sealing performance is reliable.
