Description
Technical field
The utility model relates to a kind of clack box, particularly relates to a kind of multifunctional valve box for LNG Liquefied natural gas cryogenic insulated cylinder.
Background technique
Because Global Oil resource reduces the increasingly stringent with various countries' Abgasgesetz increasingly, and the continually developing of natural gas resource, natural gas engine has been subject to promotion and application widely in many countries.The outstanding advantages of rock gas is to have good low emission characteristic and low fuel consumption, can meet more and more stricter emission regulation demands, and natural gas resource is abundant, cheap, so it is a kind of large rising internal-combustion engine alternative fuel.Wherein, take rock gas as main fuel, a small amount of diesel oil is called duel fuel engine as the motor of pilot fuel work.The valve seat construction part of original duel fuel engine is more, and layout is unreasonable, and Security is poor, and function is more single.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of multifunctional valve box, and it is simple in structure, rationally distributed, safe, has realized equally emptying, discharge opeing, safety relief etc. multi-functional.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of multifunctional valve box, it comprises the first stop valve, valve body, charging line, safety relief piece, safety valve, Restrictor Valves, bolt, the second stop valve, the first flange, the 3rd stop valve, the second flange, the first stop valve is connected with a side of valve body, charging line is connected with in the middle of valve body, the first flange is between valve body and the second flange, between safety relief piece and valve body, be bolted, safety valve is arranged in safety relief piece, and be connected with valve body, Restrictor Valves is connected with safety relief piece, the second stop valve is connected with the opposite side of valve body, the 3rd stop valve is connected with the first flange.
Preferably, described the second flange is connected with a LNG Liquefied natural gas cryogenic insulated cylinder.
Preferably, described LNG Liquefied natural gas cryogenic insulated cylinder is automobile-use LNG Liquefied natural gas cryogenic insulated cylinder or boats and ships LNG Liquefied natural gas cryogenic insulated cylinder.
Positive progressive effect of the present utility model is: the utility model multifunctional valve box simple in structure, rationally distributed, easy and simple to handle, safe, has realized emptying, discharge opeing, safety relief etc. multi-functional equally.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model multifunctional valve box.
Fig. 2 is the structure sectional view of the utility model multifunctional valve box.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model multifunctional valve box comprises the first stop valve 1, valve body 2, charging line 3, safety relief piece 4, bolt 5, the second stop valve 6, the first flange 7, the 3rd stop valve 8, the second flange 9, tank body 10, safety valve 11, Restrictor Valves 12, the first stop valve 1 is connected with a side of valve body 2, charging line 3 is connected with in the middle of valve body 2, the first flange 7 is between valve body 2 and the second flange 9, between safety relief piece 4 and valve body 2, by bolt 5, be connected, safety valve 11 is arranged in safety relief piece 4, and be connected with valve body 2, Restrictor Valves 12 is connected with safety relief piece 4, the second stop valve 6 is connected with the opposite side of valve body 2, the 3rd stop valve 8 is connected with the first flange 7.The second flange 9 is fixed on a LNG Liquefied natural gas cryogenic insulated cylinder 10.
Valve body adopts brass material and connects the first stop valve, the second stop valve; When storage pressure is too high, manual unlocking the second stop valve exhaust.The second stop valve discharges pressure of the inside of a bottle, in topping up process, forbids to open; When supercharging pressure is too high, manual unlocking the first stop valve is discharged into return-air station by pressure of the inside of a bottle.The centre of valve body is connected with charging line, safe and reliable.As shown in Figure 2, safety valve 11 is connected with valve body 2, can directly discharge the superpressure of gas cylinder.Between safety relief piece 4 and valve body 2, be bolted, Restrictor Valves 12 is connected with safety relief piece 4, and gas or the liquid of discharge can be drained along exterior line, safer.The utility model multifunctional valve box simple in structure, rationally distributed, easy and simple to handle, safe, has realized emptying, discharge opeing, safety relief etc. multi-functional equally.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
