Abstract
The utility model proposes a kind of can the LNG mounted gas cylinder system of Automatic-boosting, LNG mounted gas cylinder is provided with air supply system, saves loop; LNG mounted gas cylinder is provided with main safety valve, secondary safety valve, the first pressure gauge, level gauge system; Its technological points is also provided with an automatic pressure augment system: the delivery outlet of LNG mounted gas cylinder to the water bath type vaporizer of air supply system import between be connected with suction pumps, water bath type vaporizer to be exported to LNG mounted gas cylinder inner, suction pumps is powered by vehicle power, the control circuit of suction pumps is connected with the switch that pressure transducer and pressure transmitter control automatically; When gas cylinder working pressure is lower than setup pressure value, suction pumps is opened, and liquid is sucked out, enter water bath type vaporizer and become gaseous state, then enter knock out drum, a part of gas can supply engine work, another part gas enters gas cylinder internal by another pipeline, to reach pressurized effect; Otherwise when gas cylinder working pressure is higher than setup pressure value, suction pumps is closed.
Description
Technical field
The utility model belongs to LNG mounted gas cylinder pipe-line system, especially a kind of can the LNG mounted gas cylinder system of Automatic-boosting.
Background technique
Existing LNG mounted gas cylinder, in order to ensure the automobile in use saturated supply of gas, on LNG is vehicle-mounted, be provided with one from pressure piping system, this pipe-line system can reach gas boosting saturation in principle, but has following problem:
1, this must use hand supercharging valve to control from pressurization system, can reach pressurized effect, and needs parking to carry out supercharging in running process; 2, its external pipeline system is drawn separately, and route is long, and interface valve is more, and expose portion is once occur that shock or artificial destruction etc. can cause cryogenic liquide to spray.Above 2 problems all will cause severe compromise.3, liquid body liquid level impact, in situation that liquid level is on the low side, supercharging slowly maybe can not increase.
Summary of the invention
The utility model proposes a kind of can the LNG mounted gas cylinder system of Automatic-boosting, can Automatic-boosting when the working pressure of LNG mounted gas cylinder is less than setting value, solve insatiable hunger and close gas boosting and gas continues supply, minimum degree reduces potential safety hazard.
The technical solution of the utility model is: a kind of can the LNG mounted gas cylinder system of Automatic-boosting, LNG mounted gas cylinder is provided with delivery outlet, implementation of port, drain; Delivery outlet connects economic valve, flow-limiting valve to water bath type vaporizer successively by output pipeline, water bath type vaporizer rear end connect knock out drum, knock out drum be exported to motor, form air supply system;
Branch line is drawn to drain in the front end that output pipeline is positioned at the first economic valve, forms and saves loop;
LNG mounted gas cylinder be provided with main safety valve, secondary safety valve, the first pressure gauge and mounted gas cylinder inside be communicated with;
LNG mounted gas cylinder is provided with level gauge system, be made up of sensor, conversion and control (transmitter), liquid level display, it is inner that sensor is arranged on LNG mounted gas cylinder, sensor produces an electrical signal linearly according to the liquid level in LNG mounted gas cylinder, and be sent to switching controller, then be sent to liquid level display by switching controller;
It is characterized in that: be also provided with an automatic pressure augment system, its structure is:
LNG mounted gas cylinder is provided with pressure transducer and pressure transmitter detection LNG mounted gas cylinder internal pressure; The delivery outlet of LNG mounted gas cylinder to water bath type vaporizer import between be connected with suction pumps by supercharging intake line, the outlet of water bath type vaporizer is inner to LNG mounted gas cylinder by supercharging output pipe, suction pumps is powered by vehicle power, the control circuit of suction pumps is connected with the switch that pressure transducer and pressure transmitter control automatically; When LNG mounted gas cylinder working pressure is lower than setup pressure value, pressure transducer and pressure transmitter automatically control suction pumps and open, liquid is sucked out, enter water bath type vaporizer to be heated and to become gaseous state, enter knock out drum again, part gas can supply engine work, and another part gas enters gas cylinder internal by another pipeline, to reach pressurized effect; Otherwise when LNG mounted gas cylinder working pressure is higher than setup pressure value, pressure transducer and pressure transmitter cut off the switch of suction pumps automatically, make it to close stopping imbibition.
Beneficial effect: the utility model LNG mounted gas cylinder system has on the basis of saving loop, air supply system, be provided with automatic pressure augment system, Automatic-boosting is become from original hand supercharging, safety guarantee, easy to operate and cost savings all improve, can Automatic-boosting when the working pressure of LNG mounted gas cylinder is less than setting value, solve full conjunction supercharging and the lasting supply of gas, minimum degree reduces potential safety hazard.
