Abstract
The utility model relates to an X-shaped fixed ratio pressure reducing valve comprising a valve body, a valve seat, a valve flap, a seal ring, a piston bush, a piston rod, a spring and a valve cover. The valve body is in the X shape which is formed by crossing the main body of the valve and the passageway connecting pipe, the valve seat and the valve flap are positioned at the passageway of the passageway connecting pipe in 45 DEG oblique arrangement, and the interior of the piston rod is provided with a radial feedback hole, the outlet of which is communicated with the passageway connecting pipe. A filter net ring is connected below the valve flap and the valve seat, and pollution discharging holes are arranged in the valve body wall at the position of the filter net ring. The utility model combines pressure reduction and filtering as an entity, can be installed in optional position, and has convenient maintenance and the characteristics that the flow isn't decreased with the decreased pressure and the back pressure of the valve does not need regulating according to fixed ration.
Description
The utility model relates to the pressure loading valve that uses on a kind of fluid line.
Existing reduction valve divides from structure three kinds: spring, spring diaphragm chip and piston proportion expression.Three kinds of structures have his own strong points and deficiency.Wherein piston proportion expression valve is to utilize pressure reduction to promote spool control orifice aperture, and the pressure before the valve, behind the valve is by certain ratio design, and downstream pressure is unadjustable.Because valve body is vertical with pipeline, maintenance is inconvenient, must pull down from pipeline.In addition, existing reduction valve does not have filtering function, damages easily.
The purpose of this utility model provides a kind of X-shaped Proprutioning pressure reducing valve, make downstream pressure by fixed than regulating automatically, will reduce pressure, filter and be integrated in one, make its installation, maintenance conveniently, working life, prolongation was reliable.
The technical solution of the utility model is such:
The X-shaped Proprutioning pressure reducing valve, comprise valve body, valve seat, flap, seal ring, piston sleeve, piston rod, spring, valve gap, it is characterized in that: valve body is to intersect the X-shaped shape by valve body and passage connecting tube, valve seat and flap are positioned at passage connecting tube passage place and are obliquely installed for 45 °, piston rod and vertical connection the above the flap, a feedback hole is radially arranged in piston rod, the outlet of feedback hole is communicated with the passage connecting tube, filtration ring net of connection is provided with pollutant exhaust hole on the valve body wall at filtration ring net place below flap, valve seat; On valve body, be provided with valve upper cover, be provided with the valve lower cover below the valve body.
Filtration ring net is a rigid cylinder shape.
Working procedure of the present utility model:
With the X-shaped Proprutioning pressure reducing valve pipeline of packing into, the passage connecting tube of valve body is connected with pipe ends, and when flap was opened, fluid passed through valve body, downstream pressure increases to setting value gradually, at this moment, spring plays the role of positioning, and makes flap keep the required aperture of setting value, fluid stops to flow behind valve, from dynamic steering when static, outlet pressure rises gradually and exceeds setting value behind the valve, disequilibrates.At this moment, fluid flows into from feedback hole and acts on piston, promotes piston rod and moves down, and spring begins pressurized, closes until flap, promptly cuts off high pressure, reaches to subtract static pressure.Set the useful area ratio that flap area and feedback hole act on piston, can obtain valve before, the downstream pressure value keeps corresponding ratio, reaches the effect of proportional pressure reducing.
The utility model has the advantages that: downstream pressure need not regulated by the ratio decompression of setting; Have and not only subtract dynamic pressure but also subtract the characteristics that static pressure, decompression do not subtract flow; Be equipped with filter screen in the valve, make decompression and filtering integral, can open the pollutant exhaust hole blowdown at any time, make valve body be not easy to damage; Valve body in the valve body and passage connecting tube intersect X-shaped shape at 45, and the working state of valve can be affected because of changing the mounting point; Only need open valve gap during maintenance and get final product, not need the integral body of valve is unloaded down from pipe network; This valve is reliable, and noiseless is applicable to that upstream pressure allows the occasion that fluctuates to some extent than stable or downstream pressure.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the X-shaped Proprutioning pressure reducing valve, comprise valve body, valve seat 3, flap 4, seal ring 5,10, piston sleeve 6, piston rod 7, spring 8, valve gap, valve body is to intersect the X-shaped shape by valve body 2 and passage connecting tube 1, valve seat 3 and flap 4 are positioned at passage connecting tube 1 passage place and are obliquely installed for 45 °, piston rod 7 and vertical connection the above the flap 4, a feedback hole 13 is radially arranged in piston rod 7, the outlet of feedback hole 13 is communicated with passage connecting tube 1, at flap 4, filtration ring net 12 of the following connection of valve seat 3 is provided with two pollutant exhaust holes 11 on valve body 2 walls at filtration ring net 12 places; Filtration ring net 12 is rigid cylinder shape wire nettings.On valve body 2, be provided with valve upper cover 9, be provided with valve lower cover 14 below the valve body 2.
Claims (2)
1, a kind of X-shaped Proprutioning pressure reducing valve, comprise valve body, valve seat, flap, seal ring, piston sleeve, piston rod, spring, valve gap, it is characterized in that: valve body is to intersect the X-shaped shape by valve body and passage connecting tube, valve seat and flap are positioned at passage connecting tube passage place and are obliquely installed for 45 °, piston rod and vertical connection the above the flap, a feedback hole is radially arranged in piston rod, the outlet of feedback hole is communicated with the passage connecting tube, filtration ring net of connection is provided with pollutant exhaust hole on the valve body wall at filtration ring net place below flap, valve seat; On valve body, be provided with valve upper cover, be provided with the valve lower cover below the valve body.
