Description

Technical Field

[0001] The utility model belongs to the technical field of argon arc welding gas protection throttling control devices, and particularly relates to an argon arc welding gas protection throttling control device for rocket recovery. Background Technique

[0002] The argon arc welding gas protection throttling control device for rocket recovery is a device specifically designed to precisely control and throttle argon gas during the argon arc welding process. This device is particularly important in rocket recovery or other high-precision welding operations because it can ensure the gas protection effect during the welding process, prevent the welding materials from being oxidized, and thus improve the welding quality and efficiency.

[0003] For example, the Chinese patent with the publication number CN210878054U discloses an argon arc welding gas protection throttling control device, including an electric control component, which includes a switching power supply, a delay component, and a solenoid valve. The switching power supply is connected to the delay component, and the solenoid valve is connected to the switching power supply through the delay component; a gas passage, which includes an intake pipe, an argon gas storage bag, a flow meter, and a delivery pipe. The solenoid valve is arranged between the intake pipe and the argon gas storage bag. The flow meter is connected to the argon gas storage bag and the delivery pipe, and the delivery pipe is connected to the welding torch. The automatic delay blocking of argon gas can be realized by using the electric control component, which prevents the waste of resources caused by forgetting to close the valve and can ensure the sealing performance.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when using this patent. For example, when using the above device, solid particles may be contained in the gas. The long-term accumulation of solid particles may cause the pipeline to be blocked, and it is necessary for personnel to clean the inside of the pipeline, which is complex and time-consuming. In view of this, we propose an argon arc welding gas protection throttling control device for rocket recovery. Content of the Utility Model

[0006] The purpose of the utility model is to provide an argon arc welding gas protection throttling control device for rocket recovery to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides an argon arc welding gas protection throttling control device for rocket recovery, including:

[0008] An intake pipe, on which a filter housing is fixedly installed. One end of the intake pipe is fixedly installed with an electromagnetic control valve, and one end of the electromagnetic control valve is fixedly installed with an outlet pipe;

[0009] Filter chamber, the filter chamber is opened in the filter housing, and a base is inserted and installed in the filter chamber. A collection box is fixedly installed on the top of the base. A fixing frame is arranged on the top of the collection box, and a filter net is fixedly installed in the fixing frame;

[0010] Power chamber, the power chamber is opened in the filter housing. Two sliding bars are slidably installed in the power chamber. Limit rods are fixedly installed at the bottoms of the two sliding bars. The lower ends of the two limit rods both extend into the base. The two limit rods are both slidably connected to the power chamber, and the two limit rods are both inserted and matched with the base;

[0011] Drive assembly, the drive assembly is located in the filter housing and is used to drive the two sliding bars to slide;

[0012] Limit assembly, the limit assembly is located in the collection box and is used to fix the position of the fixing frame.

[0013] In this technical solution, the gas first enters the filter chamber through the intake pipe, and then is filtered by the filter net. Then the gas enters the electromagnetic control valve. By setting the electromagnetic control valve, the switch of gas transmission can be controlled. Then it is transported to the next process through the outlet pipe. The solid particles filtered by the filter net will fall into the collection box under the action of gravity and be collected, ensuring that the gas does not contain solid particles and the electromagnetic control valve will not be blocked by solid particles;

[0014] By setting the drive assembly, the two sliding bars can be driven to slide and move away from each other. The two sliding bars drive the two limit rods to slide and move away from each other respectively. When both limit rods are disengaged from the base, the staff can pull down the base, the sealing frame and the collection box to disengage from the filter housing. Then the staff can clean the solid particles in the collection box, ensuring that the filter net will not be blocked by too many solid particles during long-term use and the filtering effect will not be reduced;

[0015] When the filter net is used for a long time, through the set limit assembly, the fixing frame can be pulled out upwards, and then a new fixing frame can be placed on the top of the collection box. Through the set limit assembly, the fixing frame can be fixed on the collection box, which is convenient for personnel to replace the filter net and does not require tools, and the operation is convenient.

[0016] In the above technical solution, further, the drive assembly includes:

[0017] Threaded rod, the threaded rod is rotatably installed in the power chamber and is located on one side of one of the sliding bars. One end of the threaded rod penetrates through the two sliding bars and extends to the outside. The threaded rod is provided with threads with opposite helix directions at both ends, and the threaded rod is threadedly connected to the two sliding bars.

[0018] In this technical solution, the staff first rotates the threaded rod. Under the action of the thread, the threaded rod drives the two sliding bars to slide and move away from each other. The two sliding bars respectively drive the two limiting rods to slide and move away from each other. When both limiting rods are disengaged from the base, the staff can pull down the base, the sealing frame and the collection box to disengage from the filter housing. Subsequently, the staff can clean out the solid particles in the collection box to ensure that the filter screen will not be blocked due to excessive solid particles during long-term use, and the filtering effect will not be reduced.

[0019] In the above technical solution, further, the limiting component includes:

[0020] Two sliding grooves, both of the two sliding grooves are opened in the collection box. A limiting block is slidably installed in the sliding groove. A plurality of springs fixed to the inner wall of the corresponding sliding groove are fixedly installed on one side of the two limiting blocks close to each other. The upper ends of the two limiting blocks both extend into the fixed frame, and both limiting blocks are inserted and matched with the fixed frame.

[0021] In this technical solution, when the filter screen is used for a long time, the staff pulls the two limiting blocks to slide and move closer to each other. The two limiting blocks respectively squeeze a plurality of springs to contract. When the two limiting blocks slide to a suitable position, the staff can pull out the fixed frame upward, then place a new fixed frame on the top of the collection box. At the same time, both limiting blocks are inserted into the fixed frame. Subsequently, the staff releases the two limiting blocks. Under the action of the rebounding force of the plurality of springs, the two limiting blocks slide and move away from each other. Then the two limiting blocks fix the fixed frame on the collection box, which is convenient for the staff to replace the filter screen and does not require tools, and the operation is convenient.
