Background technique
At present, realize what the high, medium and low voltage classification was inflated at the inner automatic sequence charger that adopts of rock gas gas-filling station, to avoid in gas replenishment process, being difficult to guarantee inflation pressure because of pressure reduces.In the prior art, the sequential inflation control gear of automatic sequence charger is made up of a plurality of spring machinery sequence valves and one-way valve, every group of pressure regulator valve of its high, medium and low voltage pipeline separates with one-way valve, combination between them connects by transit joints such as tee union, elbow, straight couplings again, its structure more complicated, assembling be cumbersome, be easy to generate leakage, the manufacture cost height, and the setting of high, medium and low voltage pipeline can not be exchanged.In addition, when arbitrary equipment danger occurs and will block the pressurized gas path immediately before the inlet of charger, remove to close a plurality of ball valves respectively and the delay time at stop.More not enough is to realize the length of run pressure monitor.
Summary of the invention
In order to overcome the above-mentioned defective that the sequential inflation controller exists in the existing automatic sequence charger, the utility model provides a kind of integrated form priority valve, it can replace baroque sequential inflation control gear fully, it is simple in structure, safe in utilization, and can realize the pressure monitor of length of run.
Above-mentioned task realizes by this way: a kind of integrated form priority valve, it is characterized in that forming by valve body, back voltage regulator, one-way control valve and air input joint, in valve body, longitudinally have an air vent, air input joint is placed on the valve body, and be communicated with intake duct, described back voltage regulator is a pressure regulator valve, totally three, evenly be arranged on the valve body, its intake duct is communicated with the valve body air vent, totally three of described one-way control valves laterally are placed on the voltage regulator of back, and its intake duct is communicated with the air outlet channel of back voltage regulator.
In technique scheme, described back voltage regulator is by the regulator valve body, regulator base, adjusting screw, spring capping, spring, the spring positioning seat, valve rod, steel ball and spool are formed, regulator base is placed on the regulator valve body, adjusting screw is placed in the top of regulator base, spring capping in its lower end and the regulator base inner chamber is connected, and link together by spring and spring positioning seat and the valve rod that is arranged in the regulator valve body, place the steel ball top in the air outlet channel to be connected with valve rod, its underpart is placed on the spool of intake duct, whole back voltage regulator passes through hole on the regulator valve body by screw and is threaded with valve body and is fixed on the valve body, the conical boss of its lower end presses the cone-shaped hole of valve body, and is provided with an O RunddichtringO on its conical surface.
In technique scheme, described one-way control valve is by valve body, gland nut, the spring seat orifice plate, spring, valve rod and O RunddichtringO are formed, be placed in the interior valve rod of valve body and the hollow shaft socket of spring seat orifice plate, spring is placed on the valve rod between valve rod chassis and the spring seat orifice plate, the gland nut and the valve body screw-thread fit of band pipe joint are placed on the valve body, its internal conical surface is close to the spring seat orifice plate, the O RunddichtringO that is placed on the valve rod chassis is close on the conical surface of valve body intake duct, valve body is made with back voltage regulator valve body disjunctor, and its intake duct is communicated with back voltage regulator air outlet channel.
End at the integrated form priority valve also is provided with a cutting ferrule straight joint that is communicated with air vent, so that directly inflate for the rock gas tank car.
The utility model is work like this: as prior art, elder generation connects tee union, stop valve and gas tube with the air outlet joint of three one-way control valves of integrated form priority valve before using, setting pressure table above tee union, then air input joint is connected tee union, stop valve and suction tude, and obstruction cartoon straight joint just can.During use, suction tude is connected with the rock gas snorkel, three gas tubes are communicated with high pressure tank or high-pressure gas cylinder group, by the counterpressure of voltage regulator after three is set basic, normal, high third gear pressure (as 15,20 and 24 megapoises) on request, start the natural gas compressor inflation at last then.This moment, rock gas was just inflated in from air input joint toward valve body through stop valve, tee union, along with the air vent internal pressure raises, preferentially wash back pressure open and make minimum back voltage regulator, as 15 megapoises, enter high pressure group gas holder or air cylinder group by one-way control valve, tee union, stop valve and gas tube.When its jar or pressure of the inside of a bottle are elevated to (this moment, high pressure group digital display manometer was shown as 20 megapoises) when pressing back pressure value that the back voltage regulator makes as 20 megapoises in second, wash wherein voltage regulator after the pressure group open, pressure group gas holder or air cylinder group during rock gas compression gas enters by one-way control valve, tee union, stop valve.When its jar or pressure of the inside of a bottle when being elevated to 20 megapoises, digital display manometer is shown as 20 megapoises synchronously, at this moment rock gas compression gas will be simultaneously to being its height, middle pressure gas holder or the inflation of air cylinder group, when their pressure inside are elevated to behind pressure value that the 3rd regulator be provided with as 24 megapoises, wash voltage regulator thereafter open, the gas of rock gas compression in like manner enters low pressure group gas holder or air cylinder group by one-way control valve, tee union, stop valve and gas tube.When its jar or pressure of the inside of a bottle when being elevated to 24 megapoises, three groups of digital display manometers are shown as 24 megapoises synchronously, at this moment rock gas compression gas will be simultaneously to being the inflation of its high, medium and low voltage gas holder or air cylinder group, be elevated to rated pressure 25 megapoises of gas holder or air cylinder group up to their pressure, compressor quits work automatically.In gas station is that automobile is sold in the process of gas, the pressure of each gas holder or air cylinder group will reduce, at this moment this equipment gas holder or air cylinder group supplemental natural gas pressurized gas that will reduce from trend pressure, its will safety, reliably, automatically keep oneself the work position of being employed is the gas station service.When if this equipment is used in refueling mother station and is the pressure car aerating, can open the stop valve that directly fills that is connected with the cutting ferrule straight joint is the tank car inflation, or also can utilize direct aerification function to sell gas for automobile during aerating peak source of the gas deficiency.Directly fill function and finish using and close stop valve, sequence control equipment is got back on the function into gas holder or the inflation of air cylinder group automatically.
From structure of the present utility model and working principle as can be known, compared with the prior art the utility model has simple in structure, low cost of manufacture, easy for installation, advantage such as is not easy to leak and the high, medium and low voltage pipeline is interchangeable.Before the inlet of charger arbitrary equipment occur dangerous, as long as just turn off the stop valve of suction port can.In addition, just can realize centralized management by the interface of pressure transducer or the interface of digital display manometer in the variation in pressure in each pipeline of remote control room remote monitoring and the gas holder.
