Description

TECHNICAL FIELD

[0001] The utility model relates to pressure reducer technical field especially is related to a high stability big flow pressure reducer. BACKGROUND

[0002] The pressure reducer is a device for reducing the high-pressure oxygen gas stored in the oxygen cylinder to the low-pressure oxygen required for gas welding work. Because the pressure in the cylinder is high, and the pressure required for gas welding and gas cutting is small, a pressure reducer is needed to reduce the high-pressure gas stored in the cylinder to low-pressure gas, and the required working pressure should be maintained stable from beginning to end. In short, the pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and maintains the stability of the output gas pressure and flow.

[0003] For example, the specific content of the large-flow pressure reducer disclosed in Chinese patent application No. CN202222117370.6 is that the front and back of the pipeline body are fixedly connected with mounting blocks. When the heating net needs to be installed, first move the support plate to be located directly below the pipeline body, then push the support plate upward, the support plate drives the heating net and the mounting frame to move, when the mounting frame moves to the outside of the mounting block, the mounting block extrudes the movable block and makes the movable block move inward in the placing groove, the movable block extrudes the spring and makes the spring deform when moving, when the mounting block is located below the movable block, the extrusion force of the mounting block on the movable block disappears, the reset spring force of the spring resets the movable block, and the mounting block is limited after the movable block is reset. It has the following technical problems:

[0004] When the heating net needs to be overhauled, the support plate needs to be disassembled, so the mounting blocks on both sides of the front and rear of the pressure reducer pipeline body need to be released from the limit. However, when the limit is released, the limit of the mounting block by the movable block needs to be released one by one, and because the movable block cannot be limited when it is away from the mounting block, multiple people need to pull the push column at the same time to disassemble the support plate of the pressure reducer pipeline body, which makes the disassembly operation of the heating net more complicated and wastes manpower.
