Embodiment Construction

[0008] Depend on figure 1 It is known that a hydraulic balance valve with variable load includes a main valve, a load adaptation valve and a control valve. The main valve and the control valve are cone valve structures, and the load adaptation valve is a slide valve structure. There are external oil ports A and B on the valve. , K, X, the spool 10 of the load adapting valve has a series of circumferential small holes, the load adapting valve includes a strong spring 8 and a weak spring 9, a diaphragm and a spring are respectively arranged at the inlet end and the outlet end, The diaphragm at the air outlet controls the diaphragm at the intake end, and the main valve and control valve adopt a cone valve structure.

[0009] When the outside is inhaled, a negative pressure is formed, first the outlet diaphragm is opened, and then the inlet diaphragm is opened due to the decrease in internal pressure, thereby outputting oxygen; when the internal pressure is reduced to less than t...

Abstract

The invention provides a hydraulic balance valve with a changeable load. The hydraulic balance valve comprises a main valve, a load adapting valve and a control valve, wherein the main valve and the control valve are of cone valve structures, the load adapting valve is of a slide valve structure, external connecting oil openings A, B, K and X are formed in the valve, a valve core 10 of the load adapting valve is provided with a series of circumferential small holes, the load adapting valve comprises a strong spring 8 and a weak spring 9, a diaphragm and a spring are respectively arranged at the air inlet end and the air outlet end, and the diaphragm arranged at the air inlet end is controlled by the diaphragm arranged at the air outlet end. The hydraulic balance valve has the advantages that the low-frequency jitter problem of the traditional balance valve can be fundamentally solved, and the size of a throttle opening can be automatically regulated according to the load change, so the energy can be saved, the use time can be prolonged by 3 to 5 times under the condition of the same volume of gas, the waste is greatly reduced, and the oxygen suction efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the category of hydraulic control valves, in particular to a hydraulic balance valve which is used for saving oxygen in the medical oxygen inhalation process and has a decompression function and can automatically adapt to load changes. Background technique [0002] Current oxygen inhalers all output gas at a constant speed, and insert the nostrils to give oxygen through the oxygen delivery tube. While the patient is breathing, oxygen can be absorbed and utilized when inhaling, and oxygen is always output when exhaling, which is mostly wasted. In order to improve the efficiency of oxygen inhalation, there is also a method of inhaling oxygen with a face mask, but after wearing it, the breathing resistance is increased, and the discharge of carbon dioxide is restricted when exhaling, so the patient will feel uncomfortable. Contents of the invention [0003] In order to solve the problem that the balance capacity of the balance ...
