Description
Technical field
The present invention relates to a kind of motor liquified gas in gas-fired equipment safety device field
Security system is clashed in combustion gas, is particularly well-suited to liquefied natural gas (LNG), liquefaction stone
The vehicle fuel gas system of oil gas (LPG) and compressed natural gas (CNG).
Background technology
Liquefied natural gas (LNG), liquefied petroleum gas (LPG) and compressed natural gas
(CNG) compared with the most conventional vehicle fuel bavin Water Oil Or Gas, it is a kind of low
Carbon clean energy resource, the application in vehicle fuel field is continuously increased.It is mainly used in
Bus, heavy truck and transport vehicle etc., can effectively reduce two after replacing fuel oil
The discharge of carbonoxide, sulfur dioxide and nitrogen oxides.But, fuel gas system exists
Secondary disaster when vehicle meets with traffic accident can not be ignored.Wherein, liquefy natural
The Main Ingredients and Appearance of gas (LNG) is methane, its storage in liquid temperature-162 DEG C, as
Leaking, its same amount gaseous natural gas volume is its storage in liquid volume about 600 times；
Compressed natural gas (CNG) stores under the pressure of 200 atmospheric pressure, once outside
Let out, a large amount of flammable vapor cloud can be formed in the short time, when meeting with traffic accident,
Driver is likely not to have the time and experience carrys out timely fuel shutoff source of the gas.Once combustion gas
Pipeline is damaged because of accident, liquefied natural gas in fuel gas cylinder, liquefied petroleum gas or
Compressed natural gas all can leak, formed flammable, can gas explosion cloud.Scene is touched because of metal
Hit the high temperature heat sources such as the spark produced or blast pipe that rub all may be ignited, danger
Evil is huge.For a large amount of passengers on bus, its harm can not be estimated especially
Amount.For personnel and the safety of property, the security performance of vehicle fuel gas system needs
Improve.
Summary of the invention
It is an object of the invention to provide a kind of vehicle fuel gas system and clash into safety valve
(ISV), it act as, when vehicle is clashed into, being automatically switched off fuel gas cylinder
Outlet, outside the fuel gas can being prevented effectively under traffic accident state in fuel gas cylinder
Let out.
The present invention is achieved by the following technical solutions:
Security system is clashed in a kind of motor liquified gas combustion gas, including hydraulic control valve,
Capillary oil pipe and shock inductor, it is characterised in that: capillary oil pipe connection hydraulic pressure control
Valve processed and shock inductor, clash into inductor and be arranged on outside fuel gas system pipeline
In protection structure, capillary oil pipe connects hydraulic pressure boosting system, and hydraulic control valve is at liquid
In opening under pressure effect, hydraulic control valve is arranged on the outlet of fuel gas cylinder,
It is closed mode during hydraulic control valve decompression, when fuel vehicle is collided, and breaks
When the outer steel structure of pipe-line system protected by fuel gas cylinder, will certainly crash through and be arranged on
Shock inductor on structural framing, now, the hydraulic oil in inductor is released out,
Cause hydraulic control valve pressure release to cut off rapidly air delivering pipeline, stop fuel cylinder supply；
Further being limited above-mentioned technical scheme, described shock inductor is for adopting
With frangible pottery or vial, there is metal shell protection set outside, is only being subject to
It is only possible to rupture during to external impact；Above-mentioned technical scheme is further limited
Fixed, clash into inductor and be arranged on fuel gas system pipeline external protective structures, hit
Hitting inductor and arrange one or more, clashing into inductor can be according to the feelings of concrete equipment
Condition is arranged on the position being easily impacted；Above-mentioned technical scheme is further limited
Fixed, capillary oil pipe is provided with topping up check-valves with being connected between hydraulic pressure boosting system, is hitting
Hitting after inductor recovers can carry out unidirectional by the hydraulic pressure boosting system of vehicle itself
Supercharging, recovers its safety protection function, prevents gas cylinder fuel gas from flowing backwards simultaneously；
Further being limited above-mentioned technical scheme, hydraulic control valve is with the most multiple
Bit function.
The method have the advantages that
The most rational in infrastructure, install easily；
The most safe and reliable.

Detailed description of the invention
With specific embodiment, present disclosure is done further below in conjunction with the accompanying drawings
Explanation:
The hydraulic control valve (ISV) of security system is clashed in a kind of motor liquified gas combustion gas
It installs and uses position as it is shown in figure 1, by existing vehicle fuel gas system
Preferred arrangement, hydraulic control valve 1A arranges the root being arranged on blowdown piping, end
Portion is equipped with manual vent valve 2, and topping up check-valves 3 is arranged on charge pipeline root,
Prevent gas cylinder fuel gas from flowing backwards.Gas cylinder from the feeding pipe of pressure charging system 4 by gas
Bottle is drawn and is changed into drawing for fuel conduit from engine, and hydraulic control valve 1B is arranged
It is arranged on the root of the outer defeated pipeline of fuel gas cylinder.
Security system hydraulic control valve (ISV) system is clashed in a kind of motor liquified gas combustion gas
As in figure 2 it is shown, hydraulic control valve 1A and hydraulic control valve 1B passes through capillary oil pipe
A connects, and capillary oil pipe a connects inductor b and c, inductor b and c and installs
On fuel cylinder structure framework, its quantity is according to fuel gas cylinder concrete peace onboard
Holding position, arranges to protect fuel gas cylinder pipeline.It is arranged in structural frames when crashing
During any one inductor b on frame or c, hydraulic oil of releasing out, the two of series connection
Individual shock safety valve 1A and 1B can fuel shutoff gas supply timely and effectively and row
Air pipe.
A kind of motor liquified gas combustion gas is clashed into security system shock sensor structure and is shown such as Fig. 3
Shown in 4, inductor b-1 and c-1 is pottery or vial, internal equipped with
Hydraulic oil, connects capillary oil pipe by hickey, and inductor b-2 and c-1 is
Metal shell protection set, be used for preventing installing or break up during maintenance inductor b-1 or
C-1, causes hydraulic fluid leak, ultimately results in hydraulic control valve 1A and 1B and closes.
Hydraulic control valve (ISV) knot of security system is clashed in a kind of motor liquified gas combustion gas
Structure is as shown in Figure 5.Hydraulic control valve 1 is closed, and wherein comprises feed liquor
Mouthful 1-1, liquid outlet 1-2, capillary oil pipe interface 1-3 and fill hydraulic oil port 1-4.
When fuel vehicle front and back collided, side collision and when falling, break and be arranged on combustion
When expecting the inductor b on gas cylinder system structural framing or c, hydraulic oil passes through capillary
Tubing interface 1-3 UNICOM leaks out to inductor b and c, clashes into safety valve 1A
With 1B decompression, spring promotes valve rod to close the logical of inlet 1-1 and liquid outlet 1-2
Road, stops fuel gas cylinder and persistently supplies, fuel gas when preventing fuel gas pipeline from rupturing
Leakage, it is to avoid unnecessary disaster occurs, and improves existing vehicle fuel gas system
Security.Again fill by filling hydraulic oil port 1-4 when clashing into safety valve 1A and 1B
During oil, oil pressure meeting holddown spring, pull valve rod open inlet 1-1 and go out simultaneously
The passage of liquid mouth 1-2, recovers fuel gas cylinder supply.Hydraulic control valve 1 is provided with
Valve bit recovery function, by manually twisting handwheel, opens inlet 1-1 and goes out liquid
The passage of mouth 1-2, hydraulic control valve 1A and 1B opens, and fuel gas cylinder can recover
Supply.After hydraulic control valve 1 pressure release, need again through filling hydraulic oil port 1-4
Replenisher force feed, changes broken impinger simultaneously, makes hydraulic control valve 1 be in
Open position, it recovers normal function.
