Summary of the invention:
The object of the present invention is to provide a kind of diaphragm-type air pressure decompression venting valve, simple in structure, make not numerous, easy to use, practicalityCan effectively control fast the pressure of gas, to reach equipment usage safety performance by force.
For achieving the above object, a kind of diaphragm-type air pressure of the present invention decompression venting valve, by adjusting screw (1), adjusts bearing (2), raisesWhole spring (3), upper adjustment spring fastening (4), lower adjustment spring (5), lower adjustment spring fastening (6), middle diaphragm (7), diaphragm base (8),Damping hole (9), spool (10), valve port (11), outer back-moving spring (12), interior back-moving spring (13), connecting bolt (14), lower valve body (15),Valve pocket (16), upper valve body (17), diaphragm chamber (18), safety valve (19) forms.
In technique scheme, described a kind of diaphragm-type air pressure decompression venting valve, is characterized in that: adjust spiral shell when rotating clockwiseWhen nail (1), upper pressure spring (3) and lower pressure spring (5) promote lower adjustment spring fastening (6), middle diaphragm (7), diaphragm base (8)With spool (10) moves down, valve port (11) is opened, air-flow is by pressure decreased after valve port, from right side output secondary pressure, once simultaneouslySome air-flow enters diaphragm chamber (18) by damping hole (9), below diaphragm, produce a thrust upwards with on adjust spring (3) and underAdjust spring (5) Spring balanced, decompression venting valve just has stable Output pressure, in the time that input pressure P1 increases, output pressure P2 page withIncrease, the pressure under diaphragm is also increased, diaphragm is upwards pushed away to spool (10) back-moving spring (12) and interior back-moving spring (13) outsideOn effect is lower, move, thereby the aperture of valve port (11) is reduced, throttling action strengthens, and is till output pressure is reduced to setting, otherwise, if defeatedEnter pressure drop, output pressure also declines thereupon, and diaphragm moves down, and valve port (11) aperture increases, and throttling action reduces, and output pressure is gone upTo set pressure, to maintain pressure stability, in the time that in pipeline, pressure exceedes authorized pressure, in order to ensure the work safety of system, from safety valve (19)Automatic vent, so that the pressure drop of system, the safety of guarantee system.
In technique scheme, described a kind of diaphragm-type air pressure decompression venting valve, its another feature is that spool (10) upper end makesBecome hemispherical, so that middle diaphragm (7) moves up and down freely, two back-moving springs, i.e. outer back-moving spring (12) are installed in the below of spool (10)With interior back-moving spring (13), prevent the too fast generation covibration of air pressure change, middle diaphragm (7) is struck out to dish simultaneously, increase its pressure regulation energyPower.
Brief description of the drawings
Fig. 1 is a kind of diaphragm-type air pressure of the present invention decompression venting valve structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of diaphragm-type air pressure of the present invention decompression venting valve is described in further detail;
As seen from Figure 1, this enforcement is a kind of diaphragm-type air pressure decompression venting valve, by adjusting screw (1), adjusts bearing (2), upper adjustmentSpring (3), upper adjustment spring fastening (4), lower adjustment spring (5), lower adjustment spring fastening (6), middle diaphragm (7), diaphragm base (8),Damping hole (9), spool (10), valve port (11), outer back-moving spring (12), interior back-moving spring (13), connecting bolt (14), lower valve body (15),Valve pocket (16), upper valve body (17), diaphragm chamber (18), safety valve (19) forms.
As seen from Figure 1, described a kind of diaphragm-type air pressure decompression venting valve, is characterized in that: adjust screw (1) when rotating clockwiseTime, upper pressure spring (3) and lower pressure spring (5) promote lower adjustment spring fastening (6), middle diaphragm (7), diaphragm base (8) and valveCore (10) moves down, and valve port (11) is opened, and air-flow, by pressure decreased after valve port, from right side output secondary pressure, once has one simultaneouslyPart air-flow enters diaphragm chamber (18) by damping hole (9), below diaphragm, produce a thrust upwards with on adjust spring (3) and lower adjustmentThe Spring balanced of spring (5), decompression venting valve just has stable Output pressure, and in the time that input pressure P1 increases, output pressure P2 page increases thereuponHeight, also increases the pressure under diaphragm, and diaphragm is upwards pushed away, and spool (10) is the effect of back-moving spring (12) and interior back-moving spring (13) outsideOn lower, move, thereby the aperture of valve port (11) is reduced, throttling action strengthens, and is till output pressure is reduced to setting, otherwise, if input is pressedPower declines, and output pressure also declines thereupon, and diaphragm moves down, and valve port (11) aperture increases, and throttling action reduces, and makes output pressure go back up to tuneConstant-pressure, to maintain pressure stability, in the time that in pipeline, pressure exceedes authorized pressure, in order to ensure the work safety of system, from safety valve (19) certainlyMoving exhaust, so that the pressure drop of system, the safety of guarantee system.
