An object of the utility model is to provide a diaphragm formula air pressure surge damping valve that reduces pressure, simple structure, make not numerous, convenient to use, the practicality is strong, pressure that can quick effective control of gases to reach the disposition of equipment security performance.
Description
Technical field:
This utility model belongs to air-pressure stable output device, is specifically related to a kind of diaphragm-type air pressure pressure maintaining valve.
Background technology:
Sort of air pressure adjusting valve is mainly used to the pressure of gas in control system, meet various pressure requirements or in order to energy-conservation, pneumatic actuator system is to use the high compressed-air-storing of pressure in air accumulator ratio, then reduce pressure and stable output is to the pressure being applicable to system, therefore the supply gas pressure of every pneumatic means is required for using decompression venting valve, to obtain stable supply gas pressure, this kind of decompression venting valve is when input pressure changes within the specific limits, output pressure can be kept constant, when in pipeline, pressure exceedes permission pressure, in order to ensure the work safety of system, from the automatic aerofluxus of relief valve, so that the pressure of system declines, the safety of guarantee system.
Utility model content:
The purpose of this utility model is to provide a kind of diaphragm-type air pressure pressure maintaining valve, simple in construction, makes the most numerous, easy to use, practical, can the most effectively control the pressure of gas, to reach equipment usage safety performance.
For reaching above-mentioned purpose, this utility model one diaphragm-type air pressure pressure maintaining valve, by adjusting screw (1), adjust bearing (2), upper adjustment 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), relief valve (19) is constituted.
nullIn technique scheme，Described a kind of diaphragm-type air pressure pressure maintaining valve，It is characterized in that: when being rotated clockwise adjusting screw (1)，Upper pressure spring (3) and lower pressure spring (5) adjust spring fastening (6) under promoting、Middle diaphragm (7)、Diaphragm base (8) and spool (10) move down，Valve port (11) is made to open，Air-flow is reduced by pressure after valve port，Secondary pressure is exported from right side，Once some air-flow is entered diaphragm chamber (18) by damping hole (9) simultaneously，Produce below diaphragm thrust upwards with on adjust spring (3) and the Spring balanced of lower adjustment spring (5)，Decompression venting valve just has stable pressure to export，When input pressure P1 increases，Output pressure P2 page increases therewith，The pressure under diaphragm is made also to increase，Diaphragm is pushed up，Upper shifting under the effect of spool (10) back-moving spring outside (12) and interior back-moving spring (13)，So that the aperture of valve port (11) reduces，Throttling action strengthens，It is till output pressure is reduced to setting，Otherwise，If input pressure declines，Then output pressure declines the most therewith，Diaphragm moves down，Valve port (11) aperture increases，Throttling action reduces，Output pressure is made to go back up to set pressure，To maintain pressure stability，When in pipeline, pressure exceedes permission pressure，In order to ensure the work safety of system，From relief valve (19) aerofluxus automatically，So that the pressure of system declines，The safety of guarantee system.
In technique scheme, described a kind of diaphragm-type air pressure pressure maintaining valve, its another feature is that spool (10) upper end is fabricated to hemispherical, so that middle diaphragm (7) moves up and down freely, two back-moving springs are installed in the lower section of spool (10), outer back-moving spring (12) and interior back-moving spring (13), prevent air pressure change too fast generation covibration, centre diaphragm (7) is struck out dish simultaneously, increase its pressure regulation ability.
Accompanying drawing explanation
Fig. 1 is this utility model one diaphragm-type air pressure pressure maintaining valve structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model one diaphragm-type air pressure pressure maintaining valve is described in further detail；
As seen from Figure 1, this enforcement is a kind of diaphragm-type air pressure pressure maintaining valve, by adjusting screw (1), adjust bearing (2), upper adjustment 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), relief valve (19) is constituted.
nullAs seen from Figure 1，Described a kind of diaphragm-type air pressure pressure maintaining valve，It is characterized in that: when being rotated clockwise adjusting screw (1)，Upper pressure spring (3) and lower pressure spring (5) adjust spring fastening (6) under promoting、Middle diaphragm (7)、Diaphragm base (8) and spool (10) move down，Valve port (11) is made to open，Air-flow is reduced by pressure after valve port，Secondary pressure is exported from right side，Once some air-flow is entered diaphragm chamber (18) by damping hole (9) simultaneously，Produce below diaphragm thrust upwards with on adjust spring (3) and the Spring balanced of lower adjustment spring (5)，Decompression venting valve just has stable pressure to export，When input pressure P1 increases，Output pressure P2 page increases therewith，The pressure under diaphragm is made also to increase，Diaphragm is pushed up，Upper shifting under the effect of spool (10) back-moving spring outside (12) and interior back-moving spring (13)，So that the aperture of valve port (11) reduces，Throttling action strengthens，It is till output pressure is reduced to setting，Otherwise，If input pressure declines，Then output pressure declines the most therewith，Diaphragm moves down，Valve port (11) aperture increases，Throttling action reduces，Output pressure is made to go back up to set pressure，To maintain pressure stability，When in pipeline, pressure exceedes permission pressure，In order to ensure the work safety of system，From relief valve (19) aerofluxus automatically，So that the pressure of system declines，The safety of guarantee system.
A kind of diaphragm-type air pressure pressure maintaining valve described as seen from Figure 1, its another feature is that spool (10) upper end is fabricated to hemispherical, so that middle diaphragm (7) moves up and down freely, two back-moving springs are installed in the lower section of spool (10), outer back-moving spring (12) and interior back-moving spring (13), prevent air pressure change too fast generation covibration, centre diaphragm (7) is struck out dish simultaneously, increase its pressure regulation ability.
The purpose of this utility model is to provide a kind of diaphragm-type air pressure pressure maintaining valve, its simple in construction, makes the most numerous, easy to use, practical, can the most effectively control the pressure of gas, to reach equipment usage safety performance.
