Abstract
A reducing valve used in locomotion-assisting car and motorcycle comprises a stopping ball, a membrane, a mandrill, a conical inlet air hole, a pressure adjusting bolt, a low pressure cavity and a high pressure cavity, etc. Under the combined force of a spring force of the stopping ball and an air pressure on the membrane, the stopping ball can open and close a high pressure draft to control an inlet volume of a high pressure air and reduce the air pressure by moving upward and downward. The stopping ball has the same moving direction with the high pressure draft, and moreover, a traditional rubber mat is changed, which greatly improves the service life of the reducing valve.
Description
The utility model relates to a kind of combustion gas motor-helping car, motorcycle reduction valve.
Reduction valve is to be used for the pressure of combustible medium in the steel cylinder is reduced to the device that starts function to accept and can evenly successively provide the combustion gas medium.Because combustion gas motor-helping car, motor exhaust damage ratio fuel oil is much smaller, therefore, many units are arranged at present at such vehicle of development, but all run into should in the steel cylinder very high pressure drop to the receptible low pressure of motor, guarantee the problem of vehicle air feed requirement under various working again, last focus concentrates on this reduction valve.Present finding reduction valve valve switch mode, structure has different, but the principle that is adopted is identical.I.e. lever principle as shown in figure two.Can the gas in the hyperbaric chamber enter low-pressure cavity by valve port, and the difference that is decided by gas pressure and spring force on the diaphragm spurs and still pushes the rubber cushion blocks that connecting rod makes the lever the other end and push down or open valve port.Lever moves repeatedly like this, and the interior gas pressure of low-pressure cavity is consistent substantially.It is less that this method is applied in gas consumption, and air demand is stablized the occasion place.As still more suitable on the small liquid gas kitchen.But be used on the vehicle then inapplicable.This be since vehicle in motion, the motor gas consumption is very big, and operating mode often changes, therefore the switch of rubber pad is very frequent, and the direction of throttle down power is opposite with the high pressure draught flow direction, and like this, the power that acts on the rubber cushion blocks just must strengthen, cause rubber cushion blocks very easily to damage, thereby reduction valve was lost efficacy.The working state of this reduction valve has only two kinds of opening and closing.
The purpose of this utility model provides a kind of steady decompression, the reduction valve that the life-span is long.
The utility model is to realize like this, change into the valve motion direction of closing the tolerance control mouth that is used for high pressure admission consistent with the high pressure draught flow direction, be about to common reverse close to change into forward close, solved high pressure draught and directly rushed at the caulking gum cushion block, the disadvantage that causes rubber cushion blocks very easily to damage.
Push rod links to each other with diaphragm, and when spring force pressed down diaphragm, push rod also just moved down, also sealing usefulness by ball toward moving down, high pressure draught just enters low-pressure cavity in hyperbaric chamber.When the gas pressure in the low-pressure cavity during greater than spring force, the diaphragm blow-up pulling push rod that makes progress upwards moves, and also up moves under the effect of high pressure draught by ball, blocks the taper inlet hole, makes pressurized gas no longer enter low-pressure cavity.
Below in conjunction with the accompanying drawing fork-like farm tool used in ancient China structural representation of the present utility model is described:
Among Fig. 1: 1. hyperbaric chamber 2 air outlets 3 low-pressure cavity, 4 end caps 5 push rods 6 springs 7 pressure regulating screws 8 taper air inlet bodies 9 diaphragms 10 are by ball 11 blend stops 12 inlet holes
Among Fig. 2: 15 low-pressure cavity, 16 end caps, 17 diaphragms, 18 springs, 19 pressure regulating screws, 20 connecting rods, 21 levers, 22 supports, 23 through holes, 24 rubber cushion blocks, 25 valves, 26 suction ports of 13 hyperbaric chambers, 14 air outlets
Among Fig. 1: be below the push rod 5 by ball 10, they are installed in the taper inlet hole 8, push rod 5 links to each other with diaphragm 9, when spring 6 promotes diaphragm 9 downwards, push rod 5 and then moves down, leave the taper inlet hole conical surface by ball 10 under the promotion of push rod 5, high pressure draught just enters low-pressure cavity 3 by taper inlet hole 8 in hyperbaric chamber 1.When the pressure in the low-pressure cavity 3 increased, diaphragm 9 upwards Peng rose, and push rod 5 and then moves up, and also just moves up under the effect of high gas flow by ball 10, blocks taper inlet hole 8 at last, and high pressure draught just is closed.This high pressure draught moving direction of closing is consistent with the high pressure draught flow direction, and it has given up traditional rubber product again as Sealing, has greatly improved the working life of reduction valve.When some decompressions are together in series, reduce pressure step by step, can obtain better effect.
