State without pressure self-packer by without press formed between self-styled spring and automatic control seat upper surface and gun body without pressing self-styled chamber to form, no pressure
Self-styled chamber is connected by the tracting pressuring hole in gun body with main valve inlet side, and no self-styled spring of pressure is arranged on automatic control seat lower surface and automatic control
On the radial ringed step of device installation cavity body inner round wall, adopted between automatic control seat periphery and self-con-tained unit installation cavity body inner round wall
Coordinated with piston type dynamic sealing.
Preferably, secondary valve gear is set between gun barrel and gun body, the secondary valve gear by auxiliary-seat, auxiliary valve core, Venturi tube,
Auxiliary valve spring and mounting seat composition, auxiliary-seat by mounting seat sealing is pressed in gun body export, mounting seat have center flow channels hole and
Annular channel, auxiliary-seat have the center flow channels hole corresponding with mounting seat and an annular channel, auxiliary valve core have with auxiliary-seat
Annular flow road junction cooperate sealing surface, Venturi tube be arranged on mounting seat center flow channels hole in, at venturi inlet end
Be provided with the check-valves that spring and steel ball form between the center flow channels hole of auxiliary-seat, on the outside of venturi outlet with mounting seat
There is annular negative pressure chamber between heart runner hole, the annular negative pressure chamber by the air entry of the through hole in mounting seat and gun barrel front end and
Automatic control chamber connects.
Preferably, posture valve is set between the through hole within the communicating pipe and mounting seat of air entry, and the posture valve is by steel ball
With control seat composition, control seat be arranged on mounting seat on through hole and between communicating pipe, control seat lower wall be formed with connection installation
The tonifying Qi hole of through hole on seat, the tonifying Qi hole have the arc opening to be cooperated with steel ball.
It is an advantage of the invention that：It is provided with the upside of self-con-tained unit without pressure self-packer, when gun body is without oil pressure, no pressure is self-styled
Chamber loses pressure, and no self-styled spring of pressure promotes automatic control seat to move up, drives needle roller to rise, and main valve, which resets, closes, and avoids operating
Problem causes oil product to leak to cause energy loss and safety problem.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is partial structurtes enlarged drawing at A in Fig. 1 of the present invention.
Fig. 3 is partial structurtes enlarged drawing at B in Fig. 1 of the present invention.
Embodiment
It is as shown in Figure 1 without pressure self-sealing refueling gun, including gun body 1, gun stock 2, handle, gun barrel 4, main valve 3, self-con-tained unit,
Device for recovering oil and gas, self-con-tained unit are made up of needle roller 9, automatic control diaphragm 5, diaphragm spring 6, automatic control seat 8, and automatic control seat 8 is arranged on rifle
In the self-con-tained unit installation cavity 7 of body 1, diaphragm spring 6 is arranged between automatic control seat 8 and automatic control diaphragm 5, in automatic control seat 8 and certainly
There is automatic control chamber between control diaphragm 5, the automatic control chamber is connected by negative pressure channel with the air entry 10 of the front end of gun barrel 4, petroleum vapor recovery
System is made up of the petroleum vapor recovery passage on gun barrel 4 and gun body 1, petroleum vapor recovery valve module 11；Nothing is provided with the upside of self-con-tained unit
Press self-packer, it is described without pressure self-packer by without pressing the nothing formed between self-styled spring 12 and the upper surface of automatic control seat 8 and gun body 1
Self-styled chamber 13 is pressed to form, no self-styled chamber 13 of pressure is connected by the tracting pressuring hole in gun body 1 with the inlet side of main valve 3, no self-styled spring of pressure
12, which are arranged on the lower surface of automatic control seat 8, installs with self-con-tained unit on the radial ringed step of the inner round wall of cavity 7, the periphery of automatic control seat 8
Piston type dynamic sealing is used to coordinate between the inner round wall of cavity 7 is installed with self-con-tained unit, as shown in Fig. 2 when the intake channel of main valve 3 loses
When going pressure, distress resolves in the self-styled chamber 13 of no pressure, automatic control seat 8 moves up, needle roller 9 be connected from the automatic control axle 16 with main valve 3 oneself
Control in the neck of core 15 and extract, main valve 3 is closed automatically, realize self-sealing function.The upper surface of cavity 7 and rifle are installed in self-con-tained unit
Diaphragm 14 is installed between body 1, realized without the sealing pressed between self-styled chamber 13 and automatic control seat 8, self-con-tained unit installation cavity 7.
Secondary valve has bivalve cored structure, its outer valve element 17 and the annular flow road junction mutual cooperation group on the auxiliary-seat 18 of secondary valve
Into external seal pair, outer spring 20 is installed between the outer back side of valve element 17 and the auxiliary valve body 19 of secondary valve；Inner spool is using steel ball 21 and pair
The centre bore of valve seat 18 cooperates composition sealing pair, the central passage of auxiliary valve body 19 the inlet end face of Venturi tube 23 and steel ball 21 it
Between inner spring 22 is installed, described negative pressure chamber is formed between the outlet side periphery of Venturi tube 23 and auxiliary valve body 19, as shown in figure 3,
When fluid flow is less than 8L/min, outer spring 20 promotes outer valve element 17 to close, and inner spring 22 is opened because elastic force design is smaller,
All fluids are by the centre bore of Venturi tube 23 by keeping negative pressure chamber to have larger self-styled negative pressure, at the end of oiling, outer valve element
17 and inner spool simultaneously close off, prevent the inner chamber of gun body 1 from leaving oil product water clock.
The through hole that air entry 10 is connected by air intake duct 24 with negative pressure chamber connects, and is set between the through hole and air intake duct 24
Posture valve 25, the posture valve 25 are made up of the steel ball being placed in the exit conicylindrical passage of air intake duct 24, and conicylindrical passage goes out
Mouth connects with through hole, as shown in Figure 1, Figure 3.In refueling process, operating personnel raise the angle of the Front-end Design of gun barrel 4 manually,
Steel ball is rolled into conicylindrical passage, is blocked the passage between air entry 10 and self-styled control chamber, is closed main valve 3, reach with
When interrupt refuel.
