It is required that the case where quiet environment, have adverse effect.
Utility model content
The purpose of this utility model is to provide for a kind of Pneumatic film sleeve regulating valve, which passes through inside and outside O-shaped
The setting of circle and SW with outside ring, significantly improves the leakproofness of valve body；By the setting of deceleration strainer and through-hole, reduce
Liquid enters the flow velocity of valve body, improves degree of regulation, and cooperates concave inward structure and a little guide pins, significantly reduces liquid pair
In the erosion of valve body and spool, the service life of regulating valve is extended；By the setting of S type pore, liquid flow velocity is being reduced
In the case of, it further reduced noise.
In order to achieve the above object, the utility model provides following technical solution: a kind of Pneumatic film sleeve low noise
Regulating valve, including valve body, sleeve, spool, valve rod, valve deck, filler, filler pressing sleeve, filler nail pressing, thin nut, executing agency, institute
It states sleeve to crimp the top into valve body by valve deck and be mutually butted on valve seat, bracket is bolted in the upper end of the valve deck, institute
Executing agency is bolted in the upper end for stating bracket, between the valve body and valve seat, the limit of sleeve upper end and valve body upper end
SW with outside ring is equipped between step and between sleeve and valve deck, the import end flanges of the valve body are equipped with filter of slowing down
Net, the deceleration strainer are equipped with the oblique guide pin of matching valve body input end bending degree, and the spool is equipped with central symmetry
Hole is pressed in the leakage of distribution, and the lower end of the sleeve is equipped with through-hole, is equipped with noise-reduction structure on the through-hole, the filler pressing sleeve
Inside and outside wall is equipped with O-ring, and the bracket is equipped with flow indicator, and the thin nut is for adjusting flow indicator pointer
Position, the noise-reduction structure includes several S type pores being parallel to each other, and the inner wall of the sleeve is equipped with for preventing spool
The tightening step of abjection, the input end most inner side of the valve body are the concave inward structure of a quarter spherical surface.
The utility model has the beneficial effects that setting of the regulating valve by inside and outside O-ring and SW with outside ring, significantly
Improve the leakproofness of valve body；By the setting of deceleration strainer and through-hole, the flow velocity that liquid enters valve body is reduced, tune is improved
Precision is saved, and cooperates concave inward structure and a little guide pins, erosion of the liquid for valve body and spool is significantly reduced, extends tune
Save the service life of valve；It further reduced noise in the case where reducing liquid flow velocity by the setting of S type pore.

Specific embodiment
We do into one a kind of Pneumatic film sleeve low noise adjustable valve described in the utility model in conjunction with attached drawing below
The explanation of step.
As shown in Figure 1 to Figure 3, a kind of Pneumatic film sleeve low noise adjustable valve of the present embodiment, including valve body 1, set
Cylinder 2, spool 3, valve rod 4, valve deck 5, filler 6, filler pressing sleeve 7, filler nail pressing 8, thin nut 9, executing agency 10, the sleeve 2
The top into valve body 1 is crimped by valve deck 5 and is mutually butted on valve seat 11, bracket 12 is bolted in the upper end of the valve deck 5,
Executing agency 10 is bolted in the upper end of the bracket 12, between the valve body 1 and valve seat 11,2 upper end of sleeve and valve body 1
SW with outside ring 13, the import hold-carrying of the valve body 1 are equipped between the limited step of upper end and between sleeve 2 and valve deck 5
Orchid is equipped with deceleration strainer 14, and the deceleration strainer 14 is equipped with the oblique guide pin 15 of matching valve body input end bending degree, institute
Leakage pressure hole 16 of the spool 3 equipped with central symmetry distribution is stated, the lower end of the sleeve 2 is equipped with through-hole 17, pacifies on the through-hole 17
