Description

The multi-functional integrated sequence control dish in compressed natural gas station
Technical field
The utility model belongs to the improvement of a kind of order controller structure at compressed natural gas station, particularly the multi-functional integrated sequence control dish in a kind of compressed natural gas station.
Background technique
At present, known sequence control dish is tandem, be first high pressure tank to be inflated after natural gas via compressor pressurizes, when high-pressure gas pressure tank reaches setting value, under the effect of gas pressure, overcome the Bomb spring power being added on sequence valve flap and open middle pressure sequence valve, to middle pressure gas holder inflation; When central pressure gas holder pressure reaches setting value; under the effect of gas pressure, overcome the Bomb spring power being added on sequence valve flap and open low pressure sequence valve, to low pressure gasholder, inflate; until three gas holder pressure of high, medium and low voltage are while all reaching high limit setting value, compressor shutdown.Due to CNG station gas selling machine get gas be sequentially according to first low pressure, in again, press, rear high pressure tank gets gas step by step.For guaranteeing that to the final inflation pressure of CNG automobile, at 20Mpa, the pressure of pressure pan just must remain on 20Mpa.Compressor to gas holder inflation sequence should be for first high pressure, press in again, rear low pressure gasholder, the pressure that could first meet high pressure tank is at 20Mpa.Existing sequence control dish is that compressed natural gas is just inflated low pressure gasholder after three sequence valve throttlings, and pressure reduction is large, and air resistance is large, and energy consumption of compressor is high.
Model utility content
The purpose of this utility model is to provide a kind of compressed natural gas station multi-functional integrated sequence control dish, can realize series, parallel, single line inflation are carried out to sequence control, technological process is simple, control unit is few, not electricity consumption, without pressurized air, the pressure loss is little, in unit time, gas flow flux is large, reduces the energy consumption of compressor.
The purpose of this utility model is achieved in that the multi-functional integrated sequence control dish in a kind of compressed natural gas station, air supply pipe is connecting cross fitting by the first valve, three interfaces of cross fitting are connecting respectively the second valve, the first one-way valve and the one 3 pass joint, and wherein the first one-way valve is by connecting pipe of pipeline bundle trailer; Second, third 3 pass joint of contacting on the pipeline that the second valve connects, an interface of the 23 pass joint is connecting the 43 pass joint by the second one-way valve, an interface of the 43 pass joint is connecting an interface of the one 3 pass joint by the first sequence valve, another interface of the one 3 pass joint is connecting high pressure tank by the second one-way valve; Another interface of the 43 pass joint is connecting the 53 pass joint, an interface of the 53 pass joint is connecting the 33 pass joint by the second sequence valve, another interface of the 33 pass joint is connecting low pressure gasholder by the 4th one-way valve, and another interface of the 43 pass joint is pressed gas holder in connecting by the 3rd one-way valve.
The utility model workflow is as follows:
1. series sequence aeration modes; After natural gas via compressor pressurizes, first directly to high pressure tank inflation, when high-pressure gas pressure tank reaches setting value, under pressure, overcome the Bomb spring power being added on the first sequence valve flap, opened middle pressure the first sequence valve and inflate to middle pressure gas holder.When central pressure gas holder pressure reaches setting value; under pressure; overcome the Bomb spring power being added on the second sequence valve flap, open low pressure the second sequence valve and inflate to low pressure gasholder, until high, medium and low voltage gas holder pressure compressor shutdown while all reaching high limit setting value.When high-pressure gas pressure tank is during lower than setting value, middle pressure the first sequence valve automatically cuts out under spring-force driven dual, now, press gas holder pressure lower than setting value, low pressure the second sequence valve automatically cuts out under spring-force driven dual, thereby preferentially to high pressure tank, inflate, so circulation realize first high pressure, press in again, the order of rear low pressure, to the working procedure of the conventional automatic sequence inflation of gas holder.
2. aeration modes in parallel; When high-pressure gas pressure tank reaches setting value, open the second valve, the 3rd one-way valve is closed automatically.Compressed natural gas is walked around first, second sequence valve, and directly, to low pressure gasholder inflation, now energy consumption of compressor is minimum.When low pressure gasholder pressure filling is when equating with middle pressure gas holder pressure, compressed natural gas through the second one-way valve and the 5th one-way valve simultaneously in, low pressure gasholder is in parallel inflates, now energy consumption of compressor is lower.When central, low pressure gasholder pressure equates with high pressure tank, compressed natural gas is simultaneously to the inflation in parallel of three gas holder of high, medium and low voltage.Until high, medium and low voltage gas holder pressure all reaches the ceiling value of setting, compressor shutdown.
3. single-point aeration modes;
(1) singly fill high pressure tank: open the first, the 4th valve, close second, third valve, realize list high pressure tank is inflated.
(2) singly fill the inflation of middle pressure gas holder: open first, second, the 5th valve, close the 3rd, the 4th, the 6th valve, realize single centering and press gas holder inflation.
(3) singly fill low pressure gasholder inflation: open first, second, the 6th valve, close the 3rd, the 4th, the 5th valve, realize and single low pressure gasholder being inflated.
(4) singly fill the inflation of tube bank trailer: open the first, the 3rd, the 5th valve, close the second, the 4th, the 6th valve, when list is inflated tube bank trailer, tube bank trailer inflation line is incorporated to middle pressure gas holder through the first sequence valve, when tube bank trailer pressure does not reach 20Mpa, the first sequence valve is located automatic closed condition under spring-force driven dual, and compressor is only to the inflation of tube bank trailer.When tube bank trailer pressure reaches 20Mpa, gas pressure overcomes the Bomb spring power on the first sequence valve flap, opens the first sequence valve and inflates to middle pressure gas holder, realizes tube bank trailer inflation pressure superpressure and automatically protects, and guarantees safety in production.
The utility model has been realized tandem to the automatic priority inflation of high, medium and low voltage gas holder; also can when high pressure tank reach setup pressure value, switch to low pressure gasholder is flung; then to the inflation in parallel of low, middle pressure gas holder; until to the inflation in parallel of high, medium and low voltage gas holder; when pressure all reaches the high limit of high, medium and low voltage gas holder setting value, compressor shutdown.Can also be to the inflation respectively arbitrarily of high, medium and low voltage gas holder, tube bank trailer.Due in, the low pressure gasholder inflation initial stage, required pressure is low energy-conservation therefore compressor outlet exhaust pressure reduces; The pressure loss through sequential disc is little, and in the unit time, gas flow flux is large, has reduced sequential disc system resistance, thereby has reduced energy consumption of compressor.
The utility model has been realized series, parallel, single line inflation has been carried out to sequence control, and technological process is simple, and control unit is few, not electricity consumption, and without pressurized air, the pressure loss is little, and in the unit time, gas flow is large, has reduced the energy consumption of compressor.
