Abstract
The utility model relates to an adjustable pressure reducing valve. The central hole of the valve body is provided with a T-shaped sliding plug, and the crossing point on the front part and the back part of the central hole is provided with an annular groove. The valve body corresponding to the annular groove is provided with a through hole communicated with the valve body, and the valve body is provided with a pressure regulating charging nozzle. The valve body outside the central hole is provided with flowing water through holes. The sum of sectional area of the flowing water through holes is the same as the sectional area of the water inlet and the water outlet of the valve. Flanges positioned on both ends of the valve body is connected with flanges of the front end head and the back end head. The front end head and back end head are respectively arched cover plates with the central holes. The outside of the front end head is provided with a short tube of a sliding plug rod, and the inner side and the outer side of the central hole of the back end head are provided with short tubes. The utility model has the advantages of simple structure and long service life.
Description
The utility model relates to a kind of valve, particularly a kind of reduction valve.
The kind of current decompression valve is a lot, proportional formula, leading type, combined type, diaphragm type, corrugated and piston type or the like.These structure of relief pressure valve complexity, cost height, maintenance difficult, spoilage height.
In view of above-mentioned deficiency the purpose of this utility model of the prior art be to provide a kind of simple in structure, cost is low, long-lived reduction valve.
The purpose of this utility model can realize by following measure: a kind of adjustable compression release valve, it is characterized in that: establish the sliding plug of T shape in the central through bore in the valve body, its sliding plug top is identical with the large diameter hole of center hole back segment, sliding stopper rod is identical with the small diameter bore of center hole leading portion, the intersection of section is provided with annular groove before and after center hole, the valve body corresponding with it is provided with one and is attached thereto logical through hole, which is provided with the pressure regulation inflation chews, be provided with the center line discharge orifice parallel on the valve body outside center hole with the valve body center line, the sectional area sum of these through holes is identical with the intake-outlet sectional area of this valve, the flange at valve body two ends links to each other with the flange of front and back end socket respectively, the front and back end socket is the arched cover board of center hole, can be equipped with the short tube of sliding stopper rod in establish in its front head outside, the interior outside all is provided with short tube on the rear head center hole.The inboard stud tube wall of rear head center hole is provided with through hole.
The utility model mainly includes: valve body, the sliding plug of T shape, front and back end socket and pressure regulation inflation are chewed.Valve body is cylindrical, is provided with central through bore in it.This central through bore divides two sections, and the diameter of back sector hole is greater than the diameter of preceding sector hole.Be provided with the sliding plug of T shape in the valve body central through bore, it is underpressure chamber and identical with its diameter that the sliding plug of its cylindricality top is positioned at the central through bore back segment.The sliding stopper rod of its cylindricality is positioned at the leading portion and the identical center hole sealing with valve body with its diameter of center hole.Intersection in the front and back section is provided with the annular groove of being convenient to the air chamber inflation again.Should be provided with one with the corresponding valve body in annular groove position and be attached thereto logical through hole, and which is provided with the pressure regulation inflation and chew.Also be provided with the center line discharge orifice parallel on the valve body outside central through bore with the valve body center line.The sectional area sum of these through holes is identical with the intake-outlet sectional area of this valve, and the water yield of turnover valve body is equated.The valve body two ends are provided with the flange that links to each other with the front and back cover flange.Wherein front head is the arched cover board that center hole is arranged.This center hole outside as water intake is provided with short tube, and the sliding stopper rod of the sliding plug of the T shape of being put in it can be with its water intake sealing.Rear head also is the arched cover board that center hole is arranged.This all is provided with short tube as the outside on the center hole of water outlet, outside short tube be connect usefulness and the inboard short tube that reaches the underpressure chamber is a water holding ring, it flows out from outlet after can making the water that enters the discharge orifice be introduced into the underpressure chamber again.
The air chamber that the utility model is chewed between valve body and the sliding plug of T shape by the pressure regulation inflation is earlier in use slowly inflated, by required pressure level pressure.When water arrives the water intake of front head, the sliding plug of water pressure pushing T shape moves backward, the sliding stopper rod that meanwhile seals water intake leaves the water intake short tube, water then enters valve body and flows to rear head through the discharge orifice, under the effect of water holding ring, enter the underpressure chamber then from the water outlet outflow, thereby realize the purpose of isometrical decompression.
Drawing is described as follows:
Fig. 1 is a cross-sectional schematic of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic representation of adjustable compression release valve illustrated in figures 1 and 2, establish the sliding plug 2 of T shape in valve body 1 central through bore.Again before and after the center hole intersection of section to be provided with the cross section be semicircular annular groove 3.On the valve body corresponding, be provided with and be attached thereto logical through hole, which is provided with the pressure regulation inflation and chew 4 with it.It is to be provided with a conduit 5 that side opening is arranged on through hole that this ventilation is chewed, and being provided with in it can be with the movable valve rod 6 of its sealing.On valve body, also be provided with center line 12 discharge orifices 7 parallel with the valve body center line.Their sectional area sums are identical with the sectional area of intake-outlet.The valve body two ends link to each other with the front and back end socket by flange.The center hole outside of arch front head 8 is provided with short tube.The outside all is provided with short tube in rear head 9 center holes of arch.The outside is that the connecting tube inboard is water holding ring 10, and its tube wall is provided with through hole, and draining is used when T-valve is sealed the dash collar extension.
The utility model has following advantage compared to existing technology: simple in structure, cost is low, long service life, Easy to maintenance; When dynamic and static pressure, can both guarantee required pressure and can arbitrarily adjust required pressure again.
