Abstract
The utility model relates to a medical oxygen supply valve which belongs to a product of a medical appliance. The utility model comprises an air bottle nipple, a valve body, a hand wheel and an air discharging mouth, wherein the hand wheel controls a shutter through a rotary rod, bypass holes are arranged on an inlet and an outlet pipes of the shutter, and an adjusting screw is arranged in a pressure relief device in order to reduce idle strokes. The utility model has the advantages of facility switching, good sealing performance, reasonable structure and long life time. The utility model which can be suitable for the oxygen supply valve with a single meter and double meters is an auxiliary matching product for a medical oxygen supply system.
Description
Technical field:
The utility model relates to medical oxygen-supplying technology field, is a kind of medical oxygen supply valve.
Background technique:
At present, the medical oxygen supply valve of market sale is divided into single table (not reducing pressure) and two table (pressure-reducing function is arranged) two kinds, main switch is needle value, because machining error, assembly error and improper use all can cause to be not closed completely, phenomenon leaks air, switch pressure is very big simultaneously, operation effort, the working life of having reduced valve.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, thereby provides a kind of rational in infrastructure, and switch is laborsaving flexibly, the medical oxygen supply valve of good airproof performance.
The purpose of this utility model realizes in the following way:
This medical oxygen supply valve comprises that gas cylinder connects mouth (1), valve (2), blocking cap (3), valve body (4), swing arm (5), handwheel (6) and outlet nozzle (14), the valve (2) of pipeline in valve body (4) that gas cylinder connects mouth (1) communicates with outlet nozzle (14), wherein, also have a bypass opening (15) at the import and export two ends of valve (2).
Outlet nozzle (14) also can have decompressor, this device is made up of shutter spring (7), valve bar (8), steel ball (9) and handwheel (11), and handwheel (11) is adjusted valve bar (8) by adjusting screw (12), adjustment spring (13) and nut (10) promotion diaphragm.
The utility model compared with prior art has following advantage:
1, main switch pressure is very little, flexibility and reliability, and phenomenon can not leak air.
2, increase bypass opening at the valve two ends and make its pressure at two ends unanimity, reduce because the resistance that pressure difference causes.
3, on the Flow-rate adjustment screw rod of two table reduction valve, set up screw, regulate because the idle stroke that systematic error causes makes it to be reduced to minimum.
4, rational in infrastructure, noise free, each part is not fragile, long service life.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model, also is embodiment 1;
Fig. 2 is the plan view (half) of Fig. 1;
Fig. 3 is embodiment 2 of the present utility model.
In Fig. 1: (1) gas cylinder connects mouth; (2) valve; (3) blocking cap; (4) valve body; (5) swing arm; (6) handwheel; (7) shutter spring; (8) valve bar; (9) steel ball; (10) nut; (11) handwheel; (12) adjust screw; (13) pressure adjusting spring; (14) outlet nozzle; (15) bypass opening.
In Fig. 2: (16) oxygen manometer; (17) flowmeter.
In Fig. 3, (18) bypass opening.
Embodiment:
Embodiment 1:
Present embodiment is the dual meter valve door, have oxygen manometer (16) and flowmeter (17), oxygen connects mouth from gas cylinder and enters valve body (14), behind valve (2), shutter spring (7), valve bar (8), flow out by outlet nozzle (14), valve (2) turnover pipeline is connected with bypass opening (15), the swing arm (5) on valve (2) top is regulated by handwheel (6), handwheel (11) is connected the other end of valve body (4) by loam cake, by adjusting screw (12), pressure adjusting spring (13) and nut (10) promote diaphragm, make its compressing valve bar (8) control gas output.
The utility model can be used on the single, double table oxygen supply valve of medical oxygen supply, is the auxiliary auxiliary products of medical oxygen system.
Claims (2)
