Abstract
The invention discloses a multifunctional valve box, which comprises a first stop valve, a valve body, a fluid filled pipeline, a safety relief block, a safety valve, an over flow valve, a bolt, a second stop valve, a first flange, a third stop valve, and a second flange. The first stop valve is connected to one side of the valve body. The fluid filled pipeline is in connection with the middle of the valve body. The first flange is positioned between the valve body and the second flange. The safety relief block and the valve are connected by the bolt. The safety valve is mounted in the safety relief block and is connected to the valve body. The over flow valve is in connection with the safety relief block. The second stop valve is connected to the other side of the valve body, and the third stop valve is connected to the first flange. The multifunctional valve box provided in the invention has the advantages of simple structure, reasonable layout, convenient operation and high safety, and also realizes the multiple functions of emptying, drainage, safety relief and the like.
Description
Technical field
The present invention relates to a kind of clack box, particularly relate to a kind of multifunctional valve box for the LNG Liquefied natural gas cryogenic insulated cylinder.
Background technique
Because the Global Oil resource reduces 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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of multifunctional valve box, and it is simple in structure, and is rationally distributed, safe, realized that equally emptying, discharge opeing, safety relief etc. are multi-functional.
the present invention 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, the 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 the middle of valve body, the first flange is between valve body and the second flange, be bolted between safety relief piece and valve body, safety valve is arranged in the safety relief piece, and with valve body, be connected, Restrictor Valves is connected with the 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 invention is: multifunctional valve box of the present invention simple in structure, rationally distributed, easy and simple to handle, safe, realized that equally emptying, discharge opeing, safety relief etc. are multi-functional.
Description of drawings
Fig. 1 is the structural representation of multifunctional valve box of the present invention.
Fig. 2 is the structure sectional view of multifunctional valve box of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
as shown in Figures 1 and 2, multifunctional valve box of the present invention 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 the middle of valve body 2, the first flange 7 is between valve body 2 and the second flange 9, be connected by bolt 5 between safety relief piece 4 and valve body 2, safety valve 11 is arranged in safety relief piece 4, and with valve body 2, be connected, 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, forbids to open in the topping up process; When supercharging pressure was too high, manual unlocking the first stop valve was discharged into the return-air station with pressure of the inside of a bottle.The centre of valve body is connected with charging line, and is 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.Be bolted between safety relief piece 4 and valve body 2, Restrictor Valves 12 is connected with safety relief piece 4, and the gas of discharging or liquid can be drained along exterior line, and is safer.Multifunctional valve box of the present invention simple in structure, rationally distributed, easy and simple to handle, safe, realized that equally emptying, discharge opeing, safety relief etc. are multi-functional.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
