Abstract
The invention provides a special pipe for butt charging of single-cylinder liquefied gas, which is mainly applied to the butt charging between two liquefied gas cylinders and comprises a high-pressure soft circular pipe made by steel filaments, wherein an interface nut is arranged at one end of the circular pipe, and a T-shaped stainless steel structure is arranged at the other end; and one outlet of the T-shaped stainless steel structure is an interface nut, and the other outlet is a valve with a switch. The special pipe provided by the invention mainly makes use of the advantage of the added valve with a switch that the exhaust and pressure reduction can be realized without removing the steel cylinders in a charging process, thereby improving the working safety and efficiency and the operation simplicity.
Description
Technical field
The present invention relates to liquefied gas charging field, being specifically related to there is no cryopump is that two bottles of counterparts under burner structure fill.
Background technique
In prior art, single bottle of liquefied gas charging process, when the pressure of filled bottle and the pressure of stock bottle are when consistent, must close after the valve of two bottles, filled bottle is unloaded and the pressure in bottle is lowerd, again will fill afterwards pipe and load onto and could continue to fill, so, bottle discharge is loaded onto again a lot of manpowers of waste, fills the nut of pipe and bottleneck and repeatedly loads and unloads friction and also increased the danger of electrostatic fire; And filled bottle, because exhaust meeting outward absorbs the moisture content in surrounding atmosphere, forms the globule bottleneck around, need again to process and just can reach the requirement filling, increase the difficulty of working.
Summary of the invention
The object of the invention is, the defect existing for above-mentioned prior art provides a kind of single bottle of counterpart to fill flexible pipe, utilizes the directly effect of exhaust step-down in filling process, has improved Security and the efficiency of work.
Technological scheme of the present invention is as follows:
A kind of single bottle of liquid gas counterpart fills dedicated pipe, it comprises the high pressure hose for connecting two steel cylinders, as the belt switch valve of row pressure effect, the belt switch valve of described dedicated pipe is welded on high pressure hose, it is characterized in that, one of described dedicated pipe is the single nut that connects bottleneck, and the other end of described dedicated pipe is a tee T structure, one outlet is the single nut that connects bottleneck, the valve that an outlet is belt switch.
Wherein, described nut all uses copper material.
Wherein, the soft pipe that described high pressure hose is worked out by steel filament.
Wherein, described tee T structure is welded by Stainless Steel Tube.
Wherein, the valve of described belt switch is copper valve.
Beneficial effect of the present invention is: the invention provides a kind of single bottle of liquefied gas counterpart and fill dedicated pipe, by the valve of the belt switch that installs additional on pipeline, can be in filling process directly exhaust step-down, and without after the cylinder valve of two bottles is closed, unload again filled steel cylinder exhaust step-down, again two bottles of connections could be continued to fill afterwards.When increasing work efficiency, simplicity and the Security of operation are increased.
Accompanying drawing explanation
A kind of single bottle of liquid gas counterpart that Fig. 1 provides for the embodiment of the present invention fills the structural representation of dedicated pipe.
Embodiment
The invention provides a kind of single bottle of liquid gas counterpart and fill dedicated pipe, for making object of the present invention, technological scheme and advantage clearer, clear and definite, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
With reference to Fig. 1, the invention provides a kind of single bottle of liquid gas counterpart and fill flexible pipe, it is mainly used in two counterparts between liquified petroleum gas cylinder and fills, comprise pipe 1, the described flexible pipe that fills is the soft pipe of high pressure that steel filament is worked out, nominal pressure is 4Mpa, and described pipe 1 comprises the valve 4 of two joint nuts 2, tee T structure 3 and switch.
By the switch valve 4 in pipe 1, to in single bottle of liquefied gas counterpart filling process, after two bottles of air pressure reach unanimously, can be in the situation that need not unloading next steel cylinder, close the cylinder valve of raw material gas cylinder, allow the pressure decreased of filled bottle, thereby can obtain continuing to fill, until allow filled bottle be full of.
In the present embodiment, described joint nut 2 is model specifications, is corresponding with steel bottle mouth, described tee T structure 3 is stainless steel, also can be copper material, the pressure minimum can bear be 4Mpa, described be welded as argon arc welding and be seamless welding; The valve 4 of described belt switch is copper valve, is also substitutable for steel valve.
It should be noted that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
Claims (5)
1. one kind single bottle liquid gas counterpart fills dedicated pipe, it comprises the high pressure hose for connecting two steel cylinders, as the belt switch valve of row pressure effect, the belt switch valve of described dedicated pipe is welded on high pressure hose, it is characterized in that, one of described dedicated pipe is the single nut that connects bottleneck, and the other end of described dedicated pipe is a tee T structure, one outlet is the single nut that connects bottleneck, the valve that an outlet is belt switch.
2. dedicated pipe according to claim 1, is characterized in that, described nut all uses copper material.
3. dedicated pipe according to claim 1, is characterized in that, the soft pipe that described high pressure hose is worked out by steel filament.
