The beneficial effect of the utility model: avoiding the presser to produce the phenomenon of freezing, having improved life, the heat transfer is effectual.
Description
Technical field
The utility model belongs to heat exchange decompressor technical field, particularly relates to a kind of heat exchange decompressor of motor rock gas.
Background technique
Existing compressed natural gas all needed the adjustment carrying out temperature and pressure before entering gas engine, general meeting realizes heat exchange heating step through over-heat-exchanger and enters the step of decompressor step-down, and the heat exchanger of existing use is in use because the factor of self structure causes the heat exchange gas weak effect that enters, the requirement that gas engine uses can not be met, follow-up remaining part need be increased heat again, so virtually add usage quantity and the user cost of parts.
Heat transferring medium in above-mentioned heat exchanger is generally the high temperature circulation water that motor provides, high-temperature water is utilized to carry out hyperthermic treatment to the rock gas entered, but within a period of time of motor ground zero, the circulating water temperature flowed out in motor is low, thus cannot realize the hyperthermic treatment to rock gas, when the rock gas that temperature is low enters step-down in decompressor, a large amount of heat can be absorbed, temperature in decompressor can be caused so low, there is the phenomenon that decompressor freezes, the component in fragile decompressor.
Model utility content
Technical problem to be solved in the utility model is: the heat exchange decompressor providing a kind of motor rock gas, cannot fully meet the technical problem entering in-engine natural gas motorcar condition with the heat exchange gas decompressor solving existing use.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of heat exchange decompressor of motor rock gas, comprise heat exchanger and decompressor that rock gas sequentially passes through, described heat exchanger has the receiving cavity that can meet charge flow rate needed for motor work cycle, the gas inlet place of described heat exchanger connects an Electric heating appliance, described heat exchanger is also arranged one for controlling the high-pressure solenoid valve of rock gas break-make in decompressor.
As improving further, described Electric heating appliance is an electric-heating plug, and described electric-heating plug is arranged in the gas inlet pipe at gas inlet place of described heat exchanger.
As improving further, described decompressor is also provided with a connecting tube joint, described connecting tube joint is communicated with the suction tude of motor by pipeline.
As improving further, the weight range of described receiving cavity splendid attire rock gas is 60kg-70kg.
As improving further, described decompressor is piston type pressure reducer.
After have employed technique scheme, the beneficial effects of the utility model are:
Because the gas inlet place of heat exchanger connects an Electric heating appliance, like this can by this heating equipment to heated by natural gas within a period of time of motor initial startup state, rapid lifting fuel gas temperature, ensure that the natural gas temperature entered in decompressor can alleviate the heat of rock gas step-down absorption, arrive freezing temperature after avoiding absorbing heat, damage the component in decompressor; Former diaphragm type pressure regulating equipment is changed simultaneously and do piston type pressure reducer, effectively promote working life; Because heat exchanger has the receiving cavity that can meet charge flow rate needed for motor work cycle, increase the cavity space capacity of heat exchanger like this, not only can meet the flow of combustion gas needed for engine operation stroke, and increase the discharge value of high-temperature water, utilize the high temperature circulation water of motor that fuel gas temperature fast lifting can be made to rational using scope, have a heating fully to combustion gas.
Owing to decompressor being also provided with a connecting tube joint, described connecting tube joint is communicated with the suction tude of motor by pipeline.The demand gas discharge change that can produce according to the working condition of motor like this, determines the change of charge flow rate, by the connection of pipeline and engine air inlet tube, realizes the compensation to air inflow.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 to Fig. 3 jointly shown in, a heat exchange decompressor for motor rock gas, comprise heat exchanger 1 and decompressor 2 that rock gas sequentially passes through, decompressor 2 is for reducing compressed natural gas pressure, make it to control in gas engine demand working pressure, and control combustion gas break-make:
Heat exchanger 1 has the receiving cavity 12 that can meet charge flow rate needed for motor work cycle, the weight range of receiving cavity 12 splendid attire rock gas can be designed to 60kg-70kg, thus greatly expand the capacity of heat exchanger 1, also improve the inflow of the high-temperature water of motor simultaneously, give the effect that the rock gas one in heat exchanger fully heats.
An Electric heating appliance is connected at the gas inlet place of heat exchanger 1, Electric heating appliance is an electric-heating plug 11, electric-heating plug 11 is arranged in the gas inlet pipe 10 at the gas inlet place of heat exchanger 1, and heating compressed natural gas, makes it the operating temperature rising to rapidly gas engine demand.
Heat exchanger 1 is also arranged one for controlling the high-pressure solenoid valve 4 of rock gas break-make in decompressor 2.Decompressor 2 reduces compressed natural gas pressure, makes it to control the working pressure in gas engine demand, and controls the combustion gas break-make in decompressor 2 by high-pressure solenoid valve 4.
Decompressor 2 is also provided with a connecting tube joint 3, connecting tube joint 3 is communicated with the suction tude of motor by pipeline.
During use, when motor just starts, because the water temperature in motor is also lower, now for avoiding the parts such as decompressor that the phenomenon of freezing occurs, the rock gas then opened in electric-heating plug 11 pairs of gas inlet pipes 10 heats in advance, after being heated to the temperature of demand, now temperature transducer meeting alarm, the rock gas heated up is first by heat exchanger 1, then enter in above-mentioned piston type pressure reducer, flow out from the gas outlet 5 of decompressor 2 afterwards, the heat that in decompression process, absorbing natural gas is a large amount of, owing to preheating rock gas, rock gas itself is made to have certain temperature, so just can supplement decompressor 2 absorbed heat, thus avoid decompressor generation icing phenomenon, after motor runs a period of time, in motor, high-temperature water enters in the heat exchanger 1 of large volume by water intake 13, to high-pressure gas heat exchange, heating engines is got back to again from water outlet 14 after low temperature water, carry out the heat exchange effect of next round, electric-heating plug 11 also stops heating simultaneously.
The decompression process of combustion gas in whole decompressor 2 carries out break-make control by high-pressure solenoid valve 4, utilizes high-pressure solenoid valve 4 can complete cut-out at the high pressure phase of combustion gas.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
