Abstract
The utility model discloses a pneumatic electromagnetic bidiaphragm pulse valve without an air cleaner and an atomized lubricator matched with the piston type impulse valve, and can decrease failure rate and simplify the system. The oscillating bidiaphragm of the pneumatic electromagnetic bidiaphragm pulse valve replaces the sliding piston with quick switch, no abrasion and long service life, so the air pressure is discharged quickly, bringing a big explosion force. The structure is more compact when the valve and a pressure vessel are made into a whole, and the utility model can be used to discharge the pressure of the system quickly and used in the system of breaking and cleaning in material transportation.
Description
Affiliated technical field
The utility model relates to the pneumatic broken arch that uses in the transportation of pneumatic fast-discharge valve and the material flow-aiding device of removing obstacles.
Background technique
At present, known pneumatic fast-discharge valve and pneumatic broken arch flow-aiding device (air bubble) great majority of removing obstacles are in the form of piston.Explosive force is little, piston need lubricate, thereby also must be equipped with oil sprayer and air-strainer, and piston still stuck phenomenon can occur, and maintenance load is big, the cost height.This sentinel valve cisco unity malfunction.
Summary of the invention
In order to overcome the deficiency of existing sentinel valve, the utility model provides a kind of air-powered electromagnetic pair diaphragm sentinel valves, and it does not need source of the gas to filter and oil sprayer, and motion of membrane does not have friction, opens and closes rapidly, triggers sensitivity, and explosive force is strong.
The technological scheme that its technical problem that solves the utility model adopts is: the normally closed 2/2-way valve of electromagnetism, Small diaphragm-piece sentinel valve and big diaphragm sentinel valve constitute the two diaphragm sentinel valves of air-powered electromagnetic.The input of the normally closed 2/2-way valve of electromagnetism and Small diaphragm-piece control chamber communicate, Small diaphragm-piece control chamber communicates by aperture on the Small diaphragm-piece and big diaphragm control chamber, big diaphragm control chamber communicates by aperture on the big diaphragm and big diaphragm lower chambers, and big or small diaphragm seals the delivery outlet of big or small sentinel valve respectively with air pressure and spring force.
Big diaphragm lower chambers can make big container and whole sentinel valve becomes one,
The beneficial effects of the utility model are: compare with piston type and save air filter and oil sprayer, reduce amount of maintenance, this novel movement parts does not have friction, sensitivity, and explosive force is strong.Pressurized container and sentinel valve integral structure compactness reduce cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model valve and pressurized container integral structure schematic representation.
In the drawings: the normally closed 2/2-way valve of electromagnetism (1), little spring (2), Small diaphragm-piece control chamber (3), Small diaphragm-piece (4), Small diaphragm-piece sentinel valve output (5), big diaphragm control chamber (6), big diaphragm sentinel valve output (7), source of the gas input (8), big diaphragm lower chambers (9), big diaphragm (10), aperture (11) on the big diaphragm, big spring (12), aperture on the Small diaphragm-piece (13).
Embodiment
Among the figure, when closing valve, source of the gas defeated (8) enters big diaphragm lower chambers (9), enter Small diaphragm-piece control chamber (3) by aperture (13) on aperture (11) and the Small diaphragm-piece on the big diaphragm, pressure reduction and big little spring (12), (2) make big or small diaphragm (10), (4) seal corresponding delivery outlet (7), (5) respectively, at this moment the sentinel valve no-output is in closed condition.
When driving valve, the normally closed 2/2-way valve of electromagnetism (1) galvanization, the atmosphere emptying is connected in the output of the normally closed 2/2-way valve of electromagnetism (1), the pressure release of Small diaphragm-piece control chamber (3), pressure overcomes the power of little spring (2) Small diaphragm-piece (4) is lifted, make big diaphragm control chamber (6) pressure release rapidly, the pressure of big diaphragm lower chambers (9) overcomes the power of big spring (12) big diaphragm (10) is upwards lifted, the pressure of big diaphragm lower chambers (9) is discharged rapidly and is sent pulse, after pulse is finished, pressure descends, big little spring (12), (2) make big or small diaphragm (10) respectively, (4) with corresponding valve port (7), (5) sealing.
Fig. 2 is the incorporate structural type of sentinel valve and pressurized container, and working principle is identical.
The pneumatic broken arch that the utility model can be used for using in the fast row of container pressure and the material transportation is removed obstacles and is helped streaming system etc.
Claims (2)
1. Pneumatic dual-diaphragm sentinel valve that constitutes by the normally closed 2/2-way valve of electromagnetism, Small diaphragm-piece sentinel valve and big diaphragm sentinel valve, it is characterized in that: the input of the normally closed 2/2-way valve of electromagnetism and Small diaphragm-piece control chamber communicate, Small diaphragm-piece control chamber communicates by aperture on the Small diaphragm-piece and big diaphragm control chamber, big diaphragm control chamber communicates by aperture on the big diaphragm and big diaphragm cavity of resorption, and big or small diaphragm seals the delivery outlet of big or small sentinel valve respectively with air pressure and spring.
2. the two diaphragm sentinel valves of air-powered electromagnetic according to claim 1 is characterized in that: big diaphragm lower chambers can make big container and whole sentinel valve becomes one.
