Comprise relief pipe and thimble, the thimble cup joints in the last mouth of pipe of relief pipe, the thimble comprises cylinder somatic part and needle point, open at the top of cylinder somatic part has the stern notch, and the lateral part is opened there is the gas tank, the relief pipe outside is equipped with the hexagon boss is equipped with the mouth of pipe, the orifice plate pinhole and time mouth of pipe in, use the utility model discloses an original function secondary of device cooperation cylinder valve throttle, ingenious step -down steady voltage, effective flow control circulation state and flow control function to the adaptation is to human minute -pressure oxygen suppliment requirement. Adopt this kind of design to simplify medical oxygen supply decompression method, reduced volume and weight, convenient to carry, can be used to health care and tourism and the individual soldier of army defends diligent equipment.
Description
Technical field
This utility model relates to gas cylinder technical field, particularly relates to a kind of Simple decompression device coordinating cylinder valve to use.
Background technology
Surviving in the animal in atmosphere and only adapt to be equivalent to the respiratory activity under an atmospheric pressure, in usual oxygen cylinder, gas storage pressure is up to 100 atmospheric pressure, it is impossible to directly for human body, it is necessary to decompression.
At the beginning of the eighties in last century, for spacefarer's health support, Beijing Space person develops at center medical oxygen supply device and turns civilian; Although medical oxygen supply device producer of China is numerous at present, but the decompressor adopted all comes from Astronaut Center of China design. These decompressor structures are complicated, generally overlap valve system 2 and are integrated into one, containing 2 valve ports, 2 valve rods, 2 handwheels and 2 set seal approach, also have 1 to 2 pieces of Pressure gauges, have cylinder valve function concurrently, and structure is extremely complex, cause that volume is big, heavy, expensive, inconvenience portable.
Utility model content
This utility model is for the defect of prior art, it is proposed to a kind of Simple decompression device coordinating cylinder valve to use, and increases pressure-reduced and-regulated function for cylinder valve.
A kind of Simple decompression device, it is made up of relief pipe 1 and thimble 2, thimble 2 is socketed in the upper orifice 11 of relief pipe 1, described thimble 2 is made up of cylinder body 21 and needle point 22, the top of described cylinder body 21 has stern notch 211, and sidepiece has air drain 212, is provided with hexagonal boss 12 outside described relief pipe 1, inside it is provided with upper orifice 11, orifice plate pin hole 13 and lower nozzle 14.
The sidepiece of described cylinder body 21 is additionally provided with external screw thread, and the screw-internal thread fit arranged with upper orifice 11 is connected.
Described air drain 212 is provided with 2, is oppositely arranged at cylinder body 21 sidepiece.
The beneficial effects of the utility model: this utility model installs a relief pipe accessory containing thimble/taper hole valve arrangement additional on conventional cylinder valve gas outlet, decrease a large amount of adnexa, therefore, bulking value cost is all had a greatly reduced quality, reduce the requirement to profile packaging, it is particularly well-suited to the combination of a kind of tubular type valve rod needle valve, if it is supporting with 1 liter capacity aluminium alloy gas cylinder, adopt soft harness dressing, it is applicable not only to health care and tourism, individual soldier Wei Qin can also be equipped, meet Plateau troops, spacefarer, parachuting, latent etc. special demand of seeking survival is abandoned at deep-sea, particularly after fill dilution laughing gas, it is applied to burn, War injury, and the analgesia of various accident trauma, sick and wounded's misery can be alleviated, reduce mortality rate, promote life quality.

In figure, 1-manages, 11-upper orifice, 12-hexagonal boss, 13-orifice plate pin hole, 14-lower nozzle, 2-thimble, 21-cylinder body, 22-needle point, 211-stern notch, 212-air drain, 3-cylinder valve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1
A kind of Simple decompression device, as shown in Figure 1-2, it is made up of relief pipe 1 and thimble 2, thimble 2 is socketed in the upper orifice 11 of relief pipe 1, and described thimble 2 is made up of cylinder body 21 and needle point 22, and the top of described cylinder body 21 has stern notch 211, sidepiece has air drain 212, it is provided with hexagonal boss 12 outside described relief pipe 1, is inside provided with upper orifice 11, orifice plate pin hole 13 and lower nozzle 14. Described orifice plate pin hole 13, as valve port, becomes choke valve with described thimble, for fluid blood pressure lowering.
The sidepiece of described cylinder body 21 is additionally provided with external screw thread, and the screw-internal thread fit arranged with upper orifice 11 is connected.
Described air drain 212 is provided with 2, is oppositely arranged at cylinder body 21 sidepiece.
Apply this device and coordinate cylinder valve original function second throttle, ingenious lowering and stabilizing blood pressure, effectively control fluid communication and flow regulating function, to adapt to human body minute-pressure oxygen supply requirement. Adopt this kind of design to simplify medical oxygen supply device decompression method, decrease volume and weight, easy to carry, can be used for health care and tourism and army individual soldier Wei Qin equipment.
Device operation principle of the present utility model: compressed oxygen in short distance pipeline continuous 2 times throttling can lowering and stabilizing blood pressure to adapt to human body acceptance degree. Compressed oxygen, after cylinder valve 3 first time throttling, further through 2 throttlings of the choke valve that needle point in described relief pipe and taper hole combine, completes lowering and stabilizing blood pressure function. Before product export, production unit use screwdriver to turn thimble at tail end translot and adjust described thimble needle point and described relief pipe internal taper hole gap, it is determined that and lock fluid outlet pressure; When oxygen supply practical operation, control fluid flow with cylinder valve opening degree.
