Fig. 1 is the multidirectional FLOW CONTROL valve of a kind of gas of a utility model generalized section.

Embodiment

In order further to set forth the technical solution of the utility model, do detailed description below in conjunction with accompanying drawing 1:

The utility model embodiment is made up of following parts:

Suction port 1; Locking nut 2; Valve cavity 6; Spring 7; Air outlet 8; Piston 9; Leakage port 11; Air outlet 16; Locking nut 15; Admission line 17; Outlet pipe 18;

Empty in the valve cavity 6, shape cylindrical or sky in other; The two ends of valve cavity 6 connect feed channel 17 respectively; Outlet pipe 18; The inside of cavity is divided into cavity by projection two space;

Have in two spaces of valve cavity 6 and the identical piston 9 of its inner diameter size, on the connecting rod of piston spring is housed; Connect admission line 17 at valve cavity 6 dextrorotation buttons, have on the chamber wall of this half space by the air outlet 8 of cavity in the cabin; On the big nut on the cavity, there is uniform gas to pass through the leakage port 11 that cavity leaks at valve cavity 6 left side spins from the cabin body; The outer tip end of admission line 17 and outlet pipe 18 is for fixing, the screw thread that is provided with easy for installation.

In order to increase the seal of piston 9 when valve cavity 6 internal activities, the sticking sealing gasket 10 that is provided with of piston wall of the leakage port 11 that leaks through cavity from the cabin body near gases at piston 9;

In order to increase the steadiness after the installation, can also below locking nut 2, be equipped with and be placed on the external retaining washer in cabin 3 when installing; Be placed on the retaining washer 5 in the body of cabin during installation; Be placed on the external retaining washer in cabin 12 when below locking nut 15, installing; Be placed on the external retaining washer in cabin 14 during installation.

In order to increase the seal that oxygen cabin in the using process of back is installed, can also be in the cabin external retaining washer 3, the retaining washer 5 that is placed on when installing in the body of cabin are placed gasket seal 4 near the face of bulkhead respectively; Be placed on the external retaining washer in cabin 12 when mounted, be placed on the external retaining washer in the cabin 14 face placement sealing gasket 13 of close bulkhead respectively when installing.

More than describe the structure of the multidirectional FLOW CONTROL valve of gas in detail, introduce the installation method of the multidirectional FLOW CONTROL valve of this gas below:

When assembling, screw off locking nut 2 and locking nut 15, take out the pad out of my cabin of retaining washer 3, retaining washer 14 and gasket seal 4, sealing gasket 13, penetrate two corresponding apertures in oxygen cabin, oppositely assembling according to top order, locking cabin body just can not leak air situation in sealing part like this.

Face is introduced the working principle of the multidirectional FLOW CONTROL valve of this gas:

Gas enters from suction port 1 when air pump starts, and gas pressure at first puts on piston 9, and with spring 7 compressions, thereby solid piston moves to left, and exposes the air outlet 8 on the valve cavity; The sealing gasket 10 that piston 9 left ends are provided with has blocked gas from the leakage port 11 that cabin body process cavity leaks near valve cavity inside left, has cut off the gas communication of inside and outside, cabin, thereby has realized the purpose of air only import but no export; Because there is certain relation air outlet 8 on the valve cavity and the position between the piston, so no matter how high the air pressure in the body of cabin is, piston is moved to left as long as there is air to enter, reach air and enter smoothly, not the requirement that can give vent to anger.

After air pump was closed, the pressure that imposes on piston 9 from suction port disappeared, and this moment, spring 7 resiliences were pushed piston to right-hand member from left end, and gas is opened through the leakage port 11 that cavity leaks from the cabin body, and the air in the body of cabin 16 overflows from the air outlet through this leakage port 11.

The external retaining washer 3 in locking nut 2, the cabin of the multidirectional FLOW CONTROL valve of this gas, be placed on retaining washer 5, valve cavity 6, piston 9 in the body of cabin when installing; Be placed on the external retaining washer in cabin 1 during installation, be placed on the external retaining washer in cabin 14, locking nut 15 when installing; Admission line 17; The material of outlet pipe 18 grades can be metal or hard plastic material;

The material of gasket seal 4, sealing gasket 10, sealing gasket 13 can be soft rubber;

The material of spring 7 can be metal.

Pass through the utility model, owing to utilized the cooperation of piston and spring, reached the control that can not need electronic equipment, only pass through the cooperation of machinery and gas, just can realize the cooperation that air inlet is given vent to anger, can make to guarantee when gas enters the cabin body, not leak, can make oxygen set up the gas channel of inside and outside, cabin out of my cabin when portion's air pump quits work rapidly again, guarantee the pressure balance in the body of cabin.

More than the multidirectional FLOW CONTROL valve of a kind of gas provided by the utility model is described in detail, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
