Abstract
The utility model discloses a kind of PAS single seat Corniform regulating valve, comprise valve rod, hexagon nut, stud bolt, pressing plate, Gland, filler, matrix liner, bonnet, gasket seal, lantern sleeve, guide ring, guide bush, valve cage, spool, valve seat, valve body.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, and two seals filler is arranged at Gland bottom, between two seals filler, has lantern sleeve, and matrix liner is arranged at filler bottom; Bonnet to being pressed on valve body, has gasket seal between bonnet and valve body by bolt; Between bonnet and valve cage, be fixed with stem guiding ring, guide bush is housed in guide ring; Between valve seat and valve body, there is gasket seal.The beneficial effects of the utility model: valve body structure compactness, droop loss is little, and negotiability is large, and adjustable extent is wide, rating curve precision is high; Self-cleaning property is good, can reduce thickness, and medium or the impurity deposition in valve extends valve working life.
Description
Technical field
The utility model relates to a kind of pipeline valve, belongs to industrial control technology field.
Background technique
When some thick media are carried in pipeline, because this material itself has higher viscosity, make the friction of its inside larger, affected the speed of carrying.In order to improve transfer efficiency, need to adopt the pipeline valve that adjusting function is good to regulate, shorten the time of delivery of medium.
Summary of the invention
The utility model is for the proposition of above problem, and develops a kind of PAS single seat Corniform regulating 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, and two seals filler is arranged at Gland bottom, between two seals filler, has lantern sleeve, and matrix liner is arranged at filler bottom; Bonnet to being pressed on valve body, has gasket seal between bonnet and valve body by bolt; Between bonnet and valve cage, be fixed with stem guiding ring, guide bush is housed in guide ring; Between valve seat and valve body, there is gasket seal.
The utility model principle and beneficial effect: adopt top guide design, valve body structure compactness, droop loss is little, and negotiability is large, and adjustable extent is wide, rating curve precision is high; Self-cleaning property is good, can reduce viscous medium or the impurity deposition in valve, can reduce the side knock of High Pressure Difference fluid to spool, reduces spool, valve vibration of bar and wearing and tearing, extends valve working life.
