Description

A kind of novel pressure modulating valve
Technical field
The utility model relates to a kind of valve, particularly a kind of pressure regulator valve.
Background technique
Pressure regulator valve is a kind of intuitively easy Flow-rate adjustment control gear, in pipe network, application traffic modulating valve directly can set flow according to design, valve can under the effect of flowing medium, the residual pressure head of automatic elimination pipeline and the flow deviation caused by pressure surge, no matter how system pressure changes all keeps setting flow substantially constant.Easily cause jam phenomenon during the valve opening and closing of existing pressure regulator valve, and between valve body and valve, sealing is poor, easily gas leak phenomenon occurs, and do not have the pressure regulating action of expection, and structure is comparatively complicated.
Summary of the invention
The purpose of this utility model is exactly cause the problem such as jam phenomenon, sealing difference for existing pressure regulator valve, proposes that a kind of structure is simple, a kind of novel pressure modulating valve that good airproof performance, pressure regulation are simple and easy to do.
Its technological scheme is: a kind of novel pressure modulating valve, primarily of valve body, valve, spring, pad, valve gap, pallet, Cock screw, screw rod, nut, bonnet, stud, primary nut, packing ring composition.Described valve gap is fixed on valve body by stud, the two ends primary nut of stud is locked, described valve body and valve cover chamber gasket seal, described bonnet is fixed on valve gap by Cock screw, described valve, spring and pallet are all placed in the inner sealing chamber of valve body and valve gap, spring compression valve and pallet, described screw rod upper end nut check, lower end is threaded with pallet by valve gap.
Described valve is coordinated by conical surface with between valve body, and valve has air hole.
Described primary nut and valve gap, between primary nut and valve body, be provided with packing ring.
Described bonnet is uniform-distribution with 4 tapped holes, and is shell construction, wall thickness is 5mm.
The beneficial effects of the utility model: valve has air hole, during valve opening and closing, air pressure inside is consistent with external pressure, safe and reliable, rotating screw bolt Regulation spring pressure, can effectively regulate pressure and guaranteed flow is stablized constant, and structure is simple, is convenient to dismounting and maintenance.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
In upper figure: 1. valve body, 2. valve, 3. spring, 4. pad, 5. valve gap, 6. pallet, 7. Cock screw, 8. screw rod, 9. nut, 10. bonnet, 11. stud, 12. primary nuts, 13. packing rings.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, a kind of novel pressure modulating valve of the utility model, primarily of valve body 1, valve 2, spring 3, pad 4, valve gap 5, pallet 6, Cock screw 7, screw rod 8, nut 9, bonnet 10, stud 11, primary nut 12, packing ring 13 forms, described valve gap 5 is fixed on valve body 1 by stud 11, the two ends primary nut 12 of stud 11 is locked, seal with pad 4 between described valve body 1 and valve gap 5, described bonnet 10 is fixed on valve gap 5 by Cock screw 7, described valve 2, spring 3 and pallet 6 are all placed in the inner sealing chamber of valve body 1 and valve gap 5, spring 3 compresses valve 2 and pallet 6, described screw rod 8 upper end nut 9 is locked, lower end is threaded with pallet 6 by valve gap 5.
Described valve 2 is coordinated by conical surface with between valve body 1, and valve 2 has air hole, and when valve 2 opens and closes, air pressure inside is consistent with external pressure.
Described primary nut 12 and valve gap 5, between primary nut 12 and valve body 1, be provided with packing ring.
Described screw rod 8 is used for Regulation spring 3 pressure, and passes through nut check.
Described bonnet 10 is uniform-distribution with 4 tapped holes, and is shell construction, wall thickness is 5mm.
During work, valve 2 is in the closed position by the pressure of spring 3, fluid flows into from valve body 1 left end hole, flow out through lower stomidium, when hydrodynamic pressure exceedes setting value, valve 2 is opened, and excess fluid just flows back to fuel tank through valve body 1 right-hand member hole pipeline between the gap after valve body 1 and valve 2 unlatching, thus make ducted hydrodynamic pressure maintain in allowed band, play pressure and regulate and flow control effect.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
