Abstract
The utility model relates to an air pressure nitrogen inflating instrument. The utility model is characterized in that a main body is in the shape of a pipe, and a stainless steel liquid outlet pipe is arranged in the main body; the periphery of the main body is provided with a final encapsulation rubber ring, a sealing sleeve, a pressure bearing and a locking ring; the upper end of the main body is slantways provided with an air inlet pipe, an air discharging pipe, a safety valve and a pressure meter; a final encapsulation cap with a final encapsulation pad and a final encapsulation rubber ring is arranged between the liquid outlet pipe and the main body; the end head of the air discharging pipe is provided with an air discharging valve with a rubber pad; the air outlet pipe end of the safety valve is provided with a pressure regulating cap. The utility model has the advantages that the pressure nitrogen inflating instrument is provided with double pressure limiting and protecting devices and can be used safely; a final encapsulation rubber ring and the sealing sleeve are arranged in a connecting position between the utility model and a liquid nitrogen tank, and leakage can not occur.
Description
The utility model belongs to the auxiliary device of splendid attire low temperature, normal pressure aerosol container, between particularly a kind of container when aiming at medical treatment and using liquid nitrogen or container and equipment room transmission and shift the device of use.
Liquid nitrogen is stored in the jar, when needs between container or container and equipment room transmission and shifting when using, normal easily the generation shifted difficulty, pressure control is improper, or pipeline can't be low temperature resistant and cracked, liquid nitrogen is gone out casualty accident.That uses at present is manual self-pressure type, does not have laborsaving, safe device.
The purpose of this utility model is; design and produce a kind of air pressure nitrogen-filling instrument; utilize the pressure of nitrogen steel cylinder to make pressure source; the air pressure nitrogen-filling instrument is connected liquid nitrogen container and by between the topping up nitrogen machinery; by dual voltage-limiting protection valve, display list; to monitor transmission, the transfer process of liquid nitrogen, ensure handling safety.
Air pressure nitrogen-filling instrument of the present utility model, form by main body, suction tude, drain pipe, it is characterized in that, main body in a tubular form, in establish the stainless steel drain pipe of direct insertion liquid nitrogen container bottom, body peripheral edge is provided with seals cushion rubber, big envelope, pressure bearing and locking circle, the main body upper lateral is provided with suction tude, exhaust tube, safety valve and pressure gauge; Be provided with the cap that seals of being with sealing mat, sealing cushion rubber between drain pipe and main body; The exhaust tube termination is provided with the bleed valve of belt glue pad; Safety valve is given vent to anger, and pipe end is provided with ball, pressure spring type pressure is regulated cap.
Using method of the present utility model is that at drain pipe place, air pressure nitrogen-filling instrument main body upper end, the metallic hose that gathers tetrafluoro by liner is connected to by on the liquid nitrogen of the machinery of the topping up nitrogen inlet, and is fastening; At air pressure nitrogen-filling instrument main body upper lateral suction tude place, connect the nitrogen steel cylinder by decompressor, adjust nitrogen steel cylinder pressure at 0.1MPa; Air pressure nitrogen-filling instrument lower end is inserted in the liquid nitrogen container lentamente, and the stainless steel drain pipe of adjusting in the air pressure nitrogen-filling instrument main body is inserted into the liquid nitrogen container inner bottom part, seals with liquid nitrogen container Stainless Steel Tube tight-lipped solid; Tighten the bleed valve of the venting pipe end of air pressure nitrogen-filling instrument, open, open the total pipe valve of nitrogen steel cylinder by the relief opening of topping up nitrogen machinery, at this moment, pressure gauge indication nitrogen steel cylinder internal pressure, turn decompressor handle, the pressure gauge indication that is kept the air pressure nitrogen-filling instrument by stop nut is about 〉=0.04MPa, liquid nitrogen can flow in the machinery, after the machinery demonstration is full of, open bleed valve, close decompressor, making the liquid nitrogen container tank pressure is 0, fills nitrogen and finishes.
The utility model has the advantages that the air pressure nitrogen-filling instrument is provided with voltage-limiting protection safety valve and pressure display table, so just on decompressor and air pressure nitrogen-filling instrument, establish dual limiting and protecting device, safe in utilization; Seal cushion rubber and big envelope being provided with the liquid nitrogen container connection part, it is firm to connect, and can not leak; On the regulating lever on the decompressor, be provided with the stop nut pressure limiting.Be applicable to the transmission of liquid nitrogen and use when shifting.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of air pressure nitrogen-filling instrument
Fig. 2 is the planimetric map of air pressure nitrogen-filling instrument
Fig. 3 is the user mode figure of air pressure nitrogen-filling instrument
As seen from the figure, air pressure nitrogen-filling instrument of the present utility model, form by main body, suction tude, drain pipe, it is characterized in that, main body 1 in a tubular form, in establish the stainless steel drain pipe 2 of direct insertion liquid nitrogen container bottom, body peripheral edge is provided with seals cushion rubber 3, big envelope 4, pressure bearing 5 and locking circle 6, the main body upper lateral is provided with suction tude 7, exhaust tube 8, safety valve 9 and pressure gauge 10; Be provided with band sealing mat 11 between drain pipe and main body, seal cushion rubber 12 seal cap 13; The exhaust tube termination is provided with the bleed valve 14 of belt glue pad; Safety valve is given vent to anger, and pipe end is provided with ball, pressure spring type pressure is regulated cap 15.Among the figure, 16 is decompressor, and 17 is the nitrogen steel cylinder, and 18 is liquid nitrogen container, and 19 is by the machinery of topping up nitrogen.
