Problems solved by technology

This patented structure effectively controls oxygen supply pressure, oxygen flow and its numerical display. Its disadvantage is that the control of oxygen flow needs to be manually adjusted through a fine-tuning switch, which has low stability and fails to fundamentally solve the problem of oxygen waste.

Embodiment Construction

[0022] like Figure 1~Figure 6 As shown, an oxygen economizer of the present invention includes a pressure stabilizer 1 , a flow controller 2 and a gas storage valve 4 equipped with a sensing valve 3 . The pressure stabilizer 1 is made up of a spring box 1-1 and a disc-shaped part 1-2. The spring box 1-1 has two upper and lower surfaces, and a boss 1-11 is arranged on its upper surface, and the upper surface of the boss is There is an eccentric hole 1-12, and there is a sealing element on the upper surface of the boss 1-11. The upper surface of the boss is connected with the lower surface of the spring box 1-1, and they move together; the boss 1-11 The lower surface is movable, and there are a certain number of springs 1-13 in the spring box 1-1, and these springs can make the lower surface of the spring box move. And the upper surface of disc-shaped part 1-2 has a groove 1-21, when this disc-shaped part 1-2 cooperates with spring box 1-1, just can utilize this groove to form...

Abstract

The invention discloses an oxygen saver, which is characterized by comprising a pressure stabilizer, a flow controller and an air storage valve, wherein the air storage valve is provided with a sense valve; the pressure stabilizer mainly comprises a spring box and a dish components; the spring box in a sealing air inlet is matched with the dish component; an air chamber is arranged in the dish component; two or more pores are arranged on the lower surface of the air chamber; a flow regulating inner turnplate communicated with the pores is arranged in the flow controller; the air storage valveis connected with the flow regulating inner turnplate; and an air sub-outlet which is externally connected with an oxygen pipe is arranged on the output end of the air storage valve. The invention can be arranged on an oxygen cylinder to control pressure and flow of oxygen output from the oxygen cylinder, so as to reach the pressure and flow requirements for normal use. The invention has the advantages of simple structure and easy control.

Description

technical field [0001] The invention relates to the technical field of flow control valves, in particular to a valve body installed on an oxygen cylinder to control the pressure and flow of oxygen coming out of the oxygen cylinder. Background technique [0002] At present, the control valves installed on a large number of oxygen cylinders are relatively simple on-off valves, which are used to control the opening and closing of oxygen cylinders, but cannot effectively control the oxygen supply pressure and oxygen flow rate in real time, resulting in excessive waste of oxygen. , the use cost is higher. For this reason, people improve existing oxygen control valve, add the flow display control valve, as patent number is CN01269110. , humidifier, characterized in that: one end of the valve body of the control valve is processed with a standard taper thread, and the other end opposite to the standard taper thread is installed with a master switch handwheel, a master switch stem,...
