Can contact with auxiliary piston 3 and main piston 7 respectively, the area of auxiliary piston 3 is less than the area of main piston 7.Main piston 7 is by main piston chamber
19 are divided into ante-chamber and back cavity.The periphery, front end in connecting rod chamber 21 is provided with cannelure 22, cannelure 22 can respectively with connecting rod chamber 21
Communicate with auxiliary piston chamber 18.Auxiliary piston 3 can seal the front end of cannelure 22, blocks the air-flow between cannelure 22 and auxiliary piston chamber 18
Path.Offering scanty stomatal 11 in connecting rod 5, the rear end of scanty stomatal 11 communicates with back cavity.Offer out in the front end side wall of connecting rod 5
Hole 10, perforate 10 communicates with scanty stomatal 11 and cannelure 22 respectively.Installing spring 2 in auxiliary piston chamber 18, spring 2 is auxiliary piston 3
Thrust backward is provided, makes auxiliary piston 3 by connecting rod 5, main piston 7 can be pushed into rear, main piston chamber 19.Offer in valve body 1
Source of the gas passage 12, one end of source of the gas passage 12 and auxiliary piston chamber 18 UNICOM, the other end of source of the gas passage 12 and main piston chamber 19
Back cavity UNICOM.Mounting and adjusting bolt 4 on valve body 1, adjusts bolt 4 and controls the source of the gas passage 12 air demand to main piston chamber 19.Valve
The rear end of body 1 is installed and is sealed lid 16, seals and sets out QI KOU 20 on lid 16, and gas outlet 20 communicates with main piston chamber 19.On valve body 1
Offering air inlet 17, air inlet 17 communicates with auxiliary piston chamber 18.Offering linked hole 15 on valve body 1, linked hole 15 communicates with ante-chamber,
To reduce the air drag that main piston 7 moves in main piston chamber 19.
Wherein main piston 7 periphery can be provided with in the second sealing ring 14 and connecting rod 5 and can be provided with the first sealing ring 13.Actual
In production process, connecting rod 5 both can be integrated with main piston 7, it is also possible to and auxiliary piston 3 one.The rear end face of main piston 7 can
To be designed as the most recessed cambered surface 23 to increase lifting surface area, increase that main piston 7 runs in main piston chamber 19 stablizes simultaneously
Property and precision.For preventing the fine crushing material in material conveying pipe 25 from entering main piston chamber 19, the normal work of impact, such as Fig. 1 institute
Show, non-return valve 8 can be installed in described gas outlet 20, but in the case of a material of conveying material is relatively big, non-return valve 8 can omit.
When specifically installing and using, as shown in Figure 3 described automatic air supply device is installed on compressed gas pipeline 24 and material
Between conveyance conduit 25, its air inlet 17 and compressed gas pipeline 24 UNICOM, gas outlet 20 and material conveying pipe 25 UNICOM.
Operation principle: when conveying is normal, main piston 7 is pushed into main piston chamber 19 by auxiliary piston 3 and connecting rod 5 by spring 2
Rear, auxiliary piston chamber 18 and cannelure 22 are obstructed, and the compressed gas in compressed gas pipeline 24 can only enter from air inlet 17
Auxiliary piston chamber 18, then regulate the laggard back cavity becoming owner of plunger shaft 19 of flow, the most again from master through source of the gas passage 12 and adjustment bolt 4
Plunger shaft 19 enters material conveying pipe 25 through non-return valve 8.When occurring line clogging or pipeline not smooth, material conveying pipe
In 25, pressure raises, and non-return valve 8 is closed, and main piston chamber 19 pressure starts to raise, after pressure raises certain numerical value, and main piston chamber
Gas pressure in 19 forms thrust forward on main piston 7, makes main piston 7 overcome the elastic force of spring 2 to promote connecting rod 5 He
Auxiliary piston 3 moves forward, and now, is linked to be by cannelure 22, perforate 10 and scanty stomatal 11 between auxiliary piston chamber 18 and main piston chamber 19
Gas circuit conducting, gases at high pressure are directly entered main piston chamber by auxiliary piston chamber 18 through cannelure 22, perforate 10 and scanty stomatal 11
In 19, substantial amounts of compressed gas moment enters main piston chamber 19 from auxiliary piston chamber 18, and then enters material conveying pipe 25, i.e. to
Instantaneous a large amount of QI invigorating in material conveying pipe 25, blow open tamper in material conveying pipe 25, make material conveying recover normal.
After once conveying is normal, in material conveying pipe 25, pressure reduces, so that pressure reduces in main piston chamber 19, now, pair is lived
Plug 3 moves after promoting main piston 7 by connecting rod 5 under spring 2 pressure effect and resets, and auxiliary piston 3 blocks auxiliary piston chamber 18 again
With cannelure 22, now, perforate 10 and the path blockade in auxiliary piston chamber 18, auxiliary piston chamber 18 and 19 liang of main piston chamber chamber are no longer
Communicate through perforate 10 and scanty stomatal 11, compressed gas still from the adjusted bolt in auxiliary piston chamber 18 4 gentle source channels 12 to main piston
Chamber 19 keeps tiny flow quantity.
As depicted in figs. 1 and 2, the adjustment plug 9 for regulating spring 2 elastic force is installed in the front end in described auxiliary piston chamber 18,
Adjust plug 9 can stretch out outside valve body 1.
As it is shown in figure 1, described air inlet 17 is opened on adjustment plug 9.In this scheme, air inlet 17 and gas outlet 20 it
Between be the linear passages being made up of auxiliary piston chamber 18, cannelure 22, perforate 10 and scanty stomatal 11, gas-flow resistance is little, instantaneous gives vent to anger
Amount is big, can be effectively improved the effect of air blowing unimpeded.
As it is shown in figure 1, install Pressure gauge 6 on described valve body 1, Pressure gauge 6 can survey the pressure in source of the gas passage 12.
As in figure 2 it is shown, the rear end face of described auxiliary piston 3 is the most convex arcwall face, this structure can add reducing auxiliary piston 3
The auxiliary piston 3 sealing effectiveness to cannelure 22 is guaranteed on the premise of work precision.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.
