Description
Technical field
A kind of sequencing valve is the utility model is related to, it is widely used in pressure-variable adsorption occasion.
Background technology
Conventional pressure-variable adsorption supply arrangement sequencing valve couples valve rod and piston using connecting rod, connecting rod and valve rod
Axiality is not easy to ensure, deviation from linearity occurs in the movement locus for ultimately resulting in valve element, easily leakage.The sealed letter of bonnet and valve rod it
Between sealed with " V " type filler and gland, in pressure-variable adsorption requires to switch frequent operating mode, it is easy to cause gas because of abrasion
External leakage.Valve rod is coupled with valve element by taper bolt, and valve element forces valve rod to be produced with valve element in the case where being acted on by fluid deflector pressure
A raw moment of torsion stress, this stress valve rod connection with valve element endoporus, radial direction taper bolt two-phase section, taper bolt by
Tension and shear stress on axle, taper bolt are very easy to fracture.
Utility model content
The purpose of this utility model is aiming at the deficiencies in the prior art, there is provided one kind is applied to free from admixture, agranular
Liquid, gas medium, it is desirable to quick tight closing, the automatic control system sequencing valve being fast and safely vented.Hermetically sealed bonnet knot

Valve rod lower end is fixed on valve element by locking cushion block and locking nut, and screw is by valve element and locking nut tightening；Using locking
Cushion block, locking nut fixed spool and valve rod mode, good from centering, seal clearance can easily be accommodated, in use, to close
The abrasion of seal ring can be changed conveniently, while when sealing ring somewhat wears, by compressing locking nut,
Make the sealing ring after abrasion continue to meet seal request, extend sequencing valve service life.The bonnet lower end is fixed on valve body,
The upper/lower terminal of bonnet is embedded with upper sleeve gasket and lower sleeve gasket respectively, and upper sleeve gasket outer wall is provided with least one by seal groove
Individual exterior seal ring and valve bonnet seal, upper sleeve gasket inwall are provided with least one inner seal ring and valve stem seal by seal groove；
The valve bonnet seal groove is provided with the outer wall sealing of at least one exterior seal ring and lower sleeve gasket, and lower sleeve gasket inwall passes through sealing
Groove is provided with least one inner seal ring and valve stem seal；The bonnet upper end is fixed with cylinder, and top, the bottom of cylinder are provided with
Upper and lower compressed air channel.
Preferably, the valve body boss and valve body are monoblock type, and sealing ring and valve body boss are annular soft sealing face.
Preferably, the valve rod stretches out cylinder upper end and is placed in cover, and induction pieces are fixed in valve stem tip, and inductive switch is in cover
Side is fixed, and induction pieces have a sensing stroke L with inductive switch.
Preferably, the locking cushion block is opening, in valve rod annular groove.
Preferably, the bonnet will all seal between valve body and cylinder, valve rod monoblock type, improve the sealing of valve
Performance.Valve element is fixed with valve rod by locking cushion block and locking nut, improves sequencing valve service life.
