Abstract
The utility model discloses a kind of PSCW sylphon seal single-seat adjusting valve, comprise valve rod, hexagon nut, stud bolt, pressing plate, Gland, filler, matrix liner, bellows, bonnet, gasket seal, guide ring, guide bush, valve cage, spool, valve seat.Actuator is transformed into input signal the variation of push rod displacement, and band ovable valve stem moves up and down, and spool is moved on to the position corresponding with input signal, the open degree of control valve; Pressing plate, is fixed Gland being pressed on bonnet by bolt simultaneously, between Gland bottom, valve rod and bonnet inwall, has stuffing box packing, and matrix liner is arranged at filler bottom; Bonnet by bolt to being pressed on valve body, between bonnet inwall and valve rod, there is seal bellows, between bonnet and valve body, have gasket seal, fixed guide ring between bonnet, valve body and valve cage, guide bush is equipped with in guide ring inside, between bonnet and guide ring, has gasket seal; Between valve seat and valve body, there is gasket seal.The beneficial effects of the utility model: simple and compact structure, runner is unimpeded, and friction factor is little, and convection cell disturbs few; Can reduce pressure medium and change the side knock to valve body, dynamic stability is good; Good seal performance, safety durable.
Description
Technical field
The utility model relates to a kind of sealed valve, belongs to technical field of sealing technology.
Background technique
In petrochemical industry, fire-fighting environmental protection, metallurgical mine, medicine and other fields, there is the enterprise of inflammable, the explosive and poisonous medium of much production, its product need to be carried by pipeline conventionally.At severe toxicity, severe corrosive, in the course of conveying of the rare special media such as radioactivity, harsh to the requirement of Security.
Summary of the invention
The utility model is for the proposition of above problem, and develops a kind of PSCW sylphon seal single-seat adjusting valve.Actuator is transformed into input signal the variation of push rod displacement, and band ovable valve stem moves up and down, and spool is moved on to the position corresponding with input signal, the open degree of control valve; Pressing plate, is fixed Gland being pressed on bonnet by bolt simultaneously, between Gland bottom, valve rod and bonnet inwall, has stuffing box packing, and matrix liner is arranged at filler bottom; Bonnet by bolt to being pressed on valve body, between bonnet inwall and valve rod, there is seal bellows, between bonnet and valve body, have gasket seal, fixed guide ring between bonnet, valve body and valve cage, guide bush is equipped with in guide ring inside, between bonnet and guide ring, has gasket seal; Between valve seat and valve body, there is gasket seal.
The utility model principle and beneficial effect: adopt the double seal design of bellows combination seal material, eliminated stem packing seal aging shortcoming fast, that easily reveal completely, improved use energy efficiency, Security increases manufacturing facilities; Adopt long guide ring design, guiding area is large, can reduce the side knock of medium differential pressure to valve rod, improves dynamic stability.
