Description
Technical field
The utility model belongs to hydraulic pressure, air pressure and electrical system interdiscipline technical field, particularly relates to a kind of hydraulic pressure, the air pressure valve group of automatically selecting mode of operation according to first order air inlet branch pressure, thus controls the mode of operation of liquid top gas Two-stage Compression cylinder.
Background technique
At the air entraining substation established without source of the gas place, rock gas is sentenced pressurized gas state by source of the gas or is shipped with liquid condition.The effect of substation is and ensures that these gases are filled with in vehicle reservation bottle with required pressure.According to the rules, the pressure in transport pressure tank tank can not more than 20MPa, therefore supercharging equipment must be established in substation.
Due to the suction pressure scope wide (3MPa ~ 20MPa) of liquid top gas Two-stage Compression cylinder, without the need to voltage stabilizing, pressure regulation, reduce equipment investment.And hydraulic oil drives, load, uninstall process is adjustable, therefore liquid top gas Two-stage Compression cylinder pattern is more and more subject to market welcome.Because suction pressure scope is wide, height enters atmospheric pressure, and cause the loss of liquid top gas Two-stage Compression cylinder operate power in two-stage compression chamber bigger than normal, the series of problems such as cause system heating, component wear, impact serious.By the analysis and research to suction pressure scope and system power dissipation, we find to there is a power flex point within the scope of suction pressure, can by reducing system power dissipation to the change of liquid top gas Two-stage Compression cylinder working pattern.
Model utility content
For overcoming the deficiencies in the prior art, the technological scheme that the utility model provides: bimodulus liquid top gas Two-stage Compression cylinder, comprise the compression cylinder being divided into two-stage, the pipeline be communicated with two stage compression cylinder respectively, and the one-way valve that pipeline is arranged, the inlet end of first order compression cylinder is provided with two position three-way valve, two position three-way valve is connected with the connecting pipeline of second level compression cylinder simultaneously, two position three-way valve presets force value, according to the size break-make of force value, first order compression cylinder connecting pipeline pressure is less than two position three-way valve and opens the connecting pipeline with second level compression cylinder according to during the force value set, control the startup of second level compression cylinder.
One-way valve and two position, three-way electromagnetic change valve modular design, be integrated in a gas route valve block;
Technique effect of the present utility model is:
1) element 3(two position, three-way electromagnetic change valve) electrical signal and first order compress inlet air pressure (P
in-1) connect, according to first order compress inlet air pressure (P
in-1) judgment component 3(two position, three-way electromagnetic change valve) and working state, thus the mode of operation of regulator solution top gas Two-stage Compression cylinder.
2) element 3(two position, three-way electromagnetic change valve) acquiescence be Spring driving station (non-power status), namely liquid top gas Two-stage Compression cylinder is in Two-stage Compression pattern.As first order compress inlet air pressure (P
in-1) higher than setting value time, element 3(two position, three-way electromagnetic change valve) must be electric, pressure commutates, make the gas extruded from the left compression cylinder of the first order through heat exchanger (2.1), element 3(two position, three-way electromagnetic change valve), one-way valve 1.9 directly leads to the next stage of heat exchanger 2.2, achieves the single stage compression mode of operation of liquid top gas Two-stage Compression cylinder.
3) 9 one-way valves and element 3(two position, three-way electromagnetic change valve) be all the gas-pressure component of standard, modular design, be integrated in a gas route valve block, element versatility is high, interchangeability good, and looking up the fault point is also very convenient, reduces user cost.
4), when first order compress inlet air pressure is low, adopt twin-tub compression, compression efficiency is high, ensures air displacement; During first order compress inlet air pressure height, adopt single cylinder compression, reduce pressure, improve compression frequency, thus air displacement increases.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
If first order compress inlet air pressure (P
in-1) lower than setting value time, two position, three-way electromagnetic change valve 3 no electric circuit, liquid top gas Two-stage Compression cylinder is in Two-stage Compression pattern.As illustrated working state, gas enters the left compression chamber of the first order from one-way valve 1.1, along with pressure oil is from the right filler opening (P of oil hydraulic cylinder
oin) enter, the piston in liquid top gas Two-stage Compression cylinder 4 is moved to the left, the pressure (P in the left compression chamber of the first order
l1) increase, force gas directly to lead to the left compression chamber in the second level through one-way valve 1.2, heat exchanger (2.1) and two position, three-way electromagnetic change valve 3, one-way valve 1.4; Pressure (P simultaneously in the right compression chamber of the first order
r1) reduce, when it is less than first order compress inlet air pressure (P
in-1) time, gas enters in the right compression chamber of the first order from one-way valve 1.8; If the second level right compression cylinder outlet pressure (P simultaneously
rout-2) when being greater than next stage setting pressure, the gas in the right compression chamber in the second level enters next stage from one-way valve 1.6, heat exchanger (2.2).This is Two-stage Compression mode of operation.
If first order compress inlet air pressure (P
in-1) when being greater than setting value, two position, three-way electromagnetic change valve 3 is energized, and liquid top gas Two-stage Compression cylinder is in single stage compression pattern.As the working state that Fig. 1 shows, gas enters the left compression chamber of the first order from one-way valve 1.1, along with pressure oil is from the right filler opening (P of oil hydraulic cylinder
oin) enter, the piston in liquid top gas Two-stage Compression cylinder 4 is moved to the left, along with the pressure (P in the left compression chamber of the first order
l1) increase, force gas directly to lead to the next stage of heat exchanger (2.2) through one-way valve 1.2, heat exchanger (2.1) and two position, three-way electromagnetic change valve 3, one-way valve 1.9; Pressure (P simultaneously in the right compression chamber of the first order
r1) reduce, when it is less than first order compress inlet air pressure (P
in-1) time, gas enters in the right compression chamber of the first order from one-way valve 1.8; Now the right compression chamber of the left compression chamber in the second level and the second level is closed, inner without pressurized gas.Now system carries out gas compression by means of only the left and right compression chamber of the first order, is called single stage compression mode of operation.
Here the automatically controlled gas circuit by means of only two position, three-way electromagnetic change valve 3 switches the dual-mode of operation pattern that just can realize liquid top gas Two-stage Compression cylinder, manipulates simple and reliablely to be suitable for realization.
