Description
Technical field
The present invention relates to a kind of valve, especially a kind of pressure regulator valve.
Background technique
High pressure direct effect self-contained pressure regulator is that one utilizes the pressure change of controlled medium own to carry out pushing executing mechanism without the need to the external energy, reaches the effect of adjustment and steady pressure automatically.Be widely used in the automatic control in the industrial departments such as chemical industry, oil, metallurgy, electric power, light textile and fire-fighting.It is poor that traditional pressure regulator valve controls progress, and valve is short for working life, cannot filtering foreign matter.
Summary of the invention
The object of the present invention is to provide a kind of control accuracy high, valve long service life, can the pressure regulator valve of filtering foreign matter.
In order to achieve the above object, technological scheme of the present invention is: a kind of pressure regulator valve, comprises valve body, valve gap, slip shaft, spool, slide block, holddown spring, spring block, adjusting screw rod, noise-reducing sleeve, Rectifier plate, valve seat and slippage guide pillar, described valve gap is fixedly connected with one end of valve body, and form valve pocket, valve seat is fixedly connected in valve body, slippage guide pillar is fixedly connected in valve body, and slide block is positioned at valve gap, and is connected with valve gap slippage, one end of described slip shaft is connected with the slippage of slippage guide pillar, the other end is fixedly connected with slide block, and spool is fixedly connected on slip shaft, and is connected with valve seat slippage, one end and the slide block of holddown spring offset, the other end and spring block offset, and adjusting screw rod is threaded with valve gap, and offset with spring block, described valve body is provided with entrance and exit, entrance and exit is all communicated with valve pocket, and described entrance and exit place is equipped with Rectifier plate, and Rectifier plate is provided with several apertures, noise-reducing sleeve is sleeved on slippage guide pillar, and is positioned at ingress.
Isolating plate is provided with between described valve body and valve gap.
Described valve gap is provided with safety cover, and safety cover is threaded with valve gap, and lid is put on adjusting screw rod.
Adopt after said structure, the present invention due to medium from ingress through Rectifier plate throttling, enter in valve after filtering out foreign matter, then after noise-reducing sleeve step-down, abating the noise, flow into valve pocket by the throttle clearance between spool and valve seat; Then flow out from outlet.Owing to adopting holddown spring and slide block structure, the pressure that holddown spring acts on slide block can be adjusted by adjusting screw rod, thus the active force of adjustment spool, when the power that medium acts on spool is greater than the pressure of holddown spring, spool will be opened, medium will flow, if the power that medium acts on spool diminishes, spool also can slowly be closed.Adjustment adjusting screw rod, makes holddown spring be compressed to suitable position, then can open and close spool to a suitable value by control media pressure.Therefore control accuracy of the present invention is high, and the adjustment of spool is by mechanical linkage structure, therefore long service life, and Rectifier plate can filtering foreign matter.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Embodiment
The present invention is further detailed explanation for the embodiment provided below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of pressure regulator valve, comprise valve body 1, valve gap 2, slip shaft 3, spool 4, slide block 5, holddown spring 6, spring block 7, adjusting screw rod 8, noise-reducing sleeve 9, Rectifier plate 10, valve seat 11 and slippage guide pillar 12, described valve gap 2 is fixedly connected with one end of valve body 1, and form valve pocket 13, valve seat 11 is fixedly connected in valve body 1, slippage guide pillar 12 is fixedly connected in valve body 1, slide block 5 is positioned at valve gap 2, and be connected with valve gap 2 slippage, one end of described slip shaft 3 is connected with slippage guide pillar 12 slippage, the other end is fixedly connected with slide block 5, spool 4 is fixedly connected on slip shaft 3, and be connected with valve seat 11 slippage, one end and the slide block 5 of holddown spring 6 offset, the other end and spring block 7 offset, adjusting screw rod 8 is threaded with valve gap 2, and offset with spring block 7, described valve body 1 is provided with entrance 14 and outlet 15, entrance 14 is all communicated with valve pocket 13 with outlet 15, described entrance 14 and outlet 15 places are equipped with Rectifier plate 10, Rectifier plate 10 is provided with several apertures, noise-reducing sleeve 9 is sleeved on slippage guide pillar 12, and be positioned at entrance 14 place.
Shown in Figure 1, in order to isolation valve body 1 medium, play step-down sealing effect, between described valve body 1 and valve gap 2, be provided with isolating plate 16.
Shown in Figure 1, in order to prevent misoperation, described valve gap 2 is provided with safety cover 17, and safety cover 17 is threaded with valve gap 2, and lid is put on adjusting screw rod 8.
Shown in Figure 1, when the present invention uses, medium, enters in valve after filtering out foreign matter from entrance 14 through Rectifier plate 10 throttling, then after noise-reducing sleeve 9 step-down, abating the noise, flows into valve pocket 13 by the throttle clearance between spool 4 and valve seat 1; Then flow out from outlet 15.Owing to adopting holddown spring 6 and slide block 5 structure, the pressure that holddown spring 6 acts on slide block 5 can be adjusted by adjusting screw rod 8, thus the active force of adjustment spool 4, when the medium power acted on spool 4 is greater than the pressure of holddown spring 6, spool 4 will be opened, medium will flow, if the power that medium acts on spool 4 diminishes, spool 4 also can slowly be closed.Adjustment adjusting screw rod 8, makes holddown spring 6 be compressed to suitable position, then can open and close spool 4 to a suitable value by control media pressure.Therefore control accuracy of the present invention is high, and the adjustment of spool is by mechanical linkage structure, therefore long service life, and Rectifier plate can filtering foreign matter.Be specially adapted to the decompression of gas in various industrial system, pressure stabilization function.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
