Abstract
The utility model relates to a piston balanced valve which comprises a valve body (1), a valve cover (2), a valve stem (3), a sealing pressing sleeve (4), a gasket (5), a valve seat (6), a valve disk (7), a balance channel (8), a balance cavity (9), a valve chamber (10) and a piston (11), and is characterized in that the piston (11) is integral and provided with a sealing groove (12); a sealing ring (13) is sleeved in the sealing groove (12); the number of the sealing groove (12) and the sealing ring (13) is one to three; the piston (11) and the sealing ring (13) are made of high temperature resistant stainless steel material; and the piston balanced valve has the advantages of easy manufacturing, low cost, high balance stability and long service life.
Description
Technical field
The utility model belongs to valve technology field, the valve that especially a kind of flap back and forth opens and closes along the valve seat center line.
Background technique
Traditional piston balanced type valve is on the valve rod in counter balance pocket piston to be set, and piston is to be welded with corrugated stainless steel tubing.This piston balanced type valve, at running hours, the frequency of okperation height under the big situation of pressure, very easily damages, and causes the balance and stability degree to reduce, thereby makes the flap poor sealing performance, and working life is short.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, a kind of piston balanced type valve easy to manufacture, the utility model purpose is achieved in that the utility model comprises valve body, valve gap, valve rod, sealed pressing sleeve, seal ring, valve seat, flap, balance channel, counter balance pocket, valve cavity and piston, it is characterized in that piston is an integral type, have seal groove on the piston, suit seal ring in the seal groove.The number of said seal groove and seal ring is 1 to 3.Piston and seal ring are to adopt resistant to elevated temperatures stainless steel material to make.
The utility model is easy to manufacture, and cost is low, has balance and stability degree height, the advantage of long service life.
