Description
Technical field
This utility model relates to a kind of armarium.
Background technology
It is the important component part of medical engineering system that medical gas is carried, and wherein induction system terminal unit is oxygen decompressor, and oxygen more than pressure 0.8MPa is reduced pressure in the scope of 0.2-0.6MPa.
Before and after the air relief valve of the common Mei of current common decompressor road, be equipped with independent ball valve, before being connected with needle valve, relief valve before Pressure gauge on decompression turnover pipeline, be connected with ball valve, whole Plant arrangement is in the confined space of 500mm * 700mm, system complex, valve configurations quantity be many, it is large to take up room, it is numerous and diverse to assemble, installation cost is high, and the fluctuation of relief outlet oxygen pressure is large.
Utility model content
The purpose of this utility model is: provide that a kind of system is simple, compact conformation, little, the assembling amount of taking up room less, prouctiveness obviously improves, cost is low a kind of medical oxygen stable-pressure device.
The purpose of this utility model realizes by following technical proposals:
A kind of medical oxygen stable-pressure device, comprise the suction line, decompression/voltage stabilizing pipeline and the outlet line that are communicated with successively, described decompression/voltage stabilizing pipeline is that two-way walks abreast and by three-way valve, is communicated with described entry and exit pipeline respectively, described decompression/voltage stabilizing pipeline is provided with decompression/stable-pressure device, is equipped with three-way valve and is communicated with pressure-detecting device and relief valve on the pipeline of described entry and exit.
In such scheme, before and after two-way decompression/stable-pressure device, 1 three-way valve is respectively set, by the pole changer of three-way valve, switches entry and exit pipeline and be communicated with the wherein road in decompression/voltage stabilizing pipeline, realize two-way decompression one fortune one standby, reduce valve configurations quantity, save space.
1 three-way valve is set respectively on the pipeline of entry and exit, three-way valve is connected with entry and exit pipeline, pressure-detecting device, relief valve respectively, save valve configurations quantity, save space, and three-way valve standard-sized sheet during routine use, realize pressure detecting and relief valve pressure release if desired, and can be by the pole changer of three-way valve while safeguarding, cut-out entry and exit pipeline is connected with pressure-detecting device, relief valve, can detect easily thus, safeguard, change pressure-detecting device, relief valve.
Whole device can be arranged in the confined space of 300mm * 500mm, more compact structure.
As selection, described decompression/stable-pressure device is decompression/pressure maintaining valve.
In such scheme, decompression/stable-pressure device can be selected various devices, as long as can realize decompression/voltage stabilizing required for the present invention; Preferred decompression/pressure maintaining valve.
As selection, described pressure-detecting device is Pressure gauge.
In such scheme, pressure-detecting device can be selected various devices, as long as can realize pressure detecting required for the present invention; Preferred pressure table.
As selection, described three-way valve is the T-shaped valve of threeway.
Aforementioned this utility model main formula case and each further selection scheme thereof can independent assortment to form a plurality of schemes; be this utility model and can adopt also claimed scheme: as this utility model; each selects to select combination in any with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technical scheme of this utility model, at this, do not do exhaustive.
The beneficial effects of the utility model:
1, two-way voltage-stabilizing, a fortune one is standby, has improved the reliability of device;
2, simple, the compact conformation of system, take up room little, installation cost is low;
3, assemble simple and easyly, can improve prouctiveness;
4, connector is few, can reduce leakage and the pressure loss of pipeline medium;
5, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the device schematic flow sheet of this utility model embodiment;
In figure, 1 is decompression/pressure maintaining valve, and 2 is the T-shaped valve of threeway, and 3 is relief valve, and 4 is Pressure gauge, and 5 is threeway clear way valve, and 10 is suction line, and 11 is decompression/voltage stabilizing pipeline, and 12 is outlet line.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, this utility model is further described.
Shown in figure 1, oxygen more than 0.8MPa enters from suction line 10, first threeway clear way valve (the T-shaped valve of threeway) 5 of first flowing through and being connected with suction line 10, on threeway clear way valve 5, be connected with Pressure gauge 4 and relief valve 3, Oxygen Flow is crossed after this threeway clear way valve 5, flow through successively the T-shaped valve 2 of threeway and enter decompression/voltage stabilizing pipeline 11, again through decompression/pressure maintaining valve 1, the T-shaped valve 2 of threeway enters outlet line 12, second the threeway clear way valve (the T-shaped valve of threeway) 5 on it of flowing through, on threeway clear way valve 5, be connected with Pressure gauge 4 and relief valve 3, oxygen pressure is down to 0.2-0.6MPa and is flowed out from outlet line 12.
By the pole changer on the T-shaped valve 2 of threeway, arrange, a fortune one that realizes two-way decompression/voltage stabilizing is standby.
The configuration of the threeway clear way valve that suction line 10 is connected respectively with outlet line 12 (the T-shaped valve of threeway) 5 is identical with connected mode, is all connected with pipeline, Pressure gauge 4 and relief valve 3.
Being connected pattern and can adopting screw thread, welding, cutting ferrule, flange etc. of pipeline and valve, instrument.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
