Description

Technical Field

[0001] The utility model belongs to the technical field of valve production equipment, and in particular relates to a valve heat treatment cooling device. Background Art

[0002] A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. A valve is a basic component in a pipeline system. During the production process, the valve usually needs to undergo heat treatment to improve the performance, hardness and durability of the valve material. During the entire heat treatment process, temperature, insulation time and cooling rate are key parameters. A valve heat treatment cooling device is a device commonly used in valve heat treatment operations. For example, a valve casting heat treatment cooling device disclosed in patent application number CN202023033816.4 includes a base, and the top of the base is fixedly connected with a shock absorber. Pad, the top of the shock-absorbing pad is fixedly connected with a control device, the top of the shock-absorbing pad is fixedly connected with a pillar, the top of the pillar is fixedly connected with a fixing plate, the bottom of the spray plate is movably connected with a nozzle, the top of the shock-absorbing pad is fixedly connected with a collecting dish, the inside of the collecting dish is fixedly connected with a support column, the inside of the collecting dish is fixedly connected with a feeding device, the inside of the collecting dish is fixedly connected with a loading device, the inside of the support column is movably connected with a first conveyor belt, the inside of the conveyor belt is movably connected with a rotating shaft, the outer wall of the rotating shaft is fixedly connected with a gear disk, and the top of the support column is movably connected with a transmission chain;

[0003] In the process of cooling the valve, the existing valve heat treatment cooling device generally directly sprays the coolant for cooling. This causes the valve to easily produce increased residual stress, deterioration or deformation, increased brittleness, abnormal metallographic structure, cracks and deformation due to excessive cooling speed during the cooling process, thereby reducing the quality of the finished valve. If the valve is left standing for a period of time and then sprayed with coolant after its temperature drops to a coolable state, the cooling efficiency of the valve will be greatly reduced, resulting in reduced work efficiency. Therefore, it is necessary to make improvements. Utility Model Content
