Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and specifically to a transition connector for a gear reducer of a butterfly valve. Background Art

[0002] A butterfly valve, also known as a flapper valve, is a simple-structured regulating valve that can be used for the on-off control of media in low-pressure pipelines. The butterfly valve refers to a valve whose closing member (valve flap or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. It mainly functions as a cut-off and throttling device in pipelines. The opening and closing member of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve opening, closing, or adjustment.

[0003] A reducer is an independent component composed of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. During the process of connecting and using the butterfly valve and the reducer, the flow rate of the liquid passing through the butterfly valve can be adjusted by the reducer.

[0004] In the prior art, such as a transition connector for a new type of gear reducer in Chinese Patent Application No. CN 203906670 U, the wind cover is arranged at one end of the machine shell, a transition connector is provided between the machine shell and the gear shell. The transition connector is composed of an external hexagonal bolt, a flange, an internal hexagonal screw, an input shaft, a bearing, and an oil seal. The machine shell and the flange are fixed by the external hexagonal bolt, and the flange and the gear shell are fixed by the internal hexagonal screw. An output shaft sprocket gear, a motor section sprocket gear, and an output section shaft gear are arranged inside the gear shell. The output shaft is embedded in the gear shell, and both the output end and the output shaft are supported by bearings at both ends. The bearings are arranged in the bearing seats of the gearbox rear cover and the gear shell, and an oil seal is provided on the input shaft. The unique design of the transition connector of the present utility model can effectively avoid the deformation and wear of parts, thereby greatly increasing the service life.

[0005] Although the above-mentioned device can effectively avoid the deformation and wear of parts, thereby greatly increasing the service life, when connecting the reducer and the switch port of the butterfly valve, since the two are in a fixed connection state, the distance between the two cannot be adjusted correspondingly, resulting in limitations in the use of the device. Moreover, the existing devices on the market are all in a solid-state connection. When the device is running, it is prone to jitter, and this jitter cannot be effectively processed, which is likely to cause the fracture of the connection port during use. Summary of the Invention

[0042] Usage method and working principle of this device: At the beginning of the operation of the device, it is respectively inserted between the inner walls of a group of second installation grooves 202 and a group of first installation grooves 102. The connecting nut 104 is rotationally connected between the outer walls of the other threaded rods 103, so as to maintain the fixed state between the main valve body 101 and the two side connecting valve bodies 201.

And before use, according to the actual situation, the moving block 508 is inserted and moved up and down inside the limiting ring 509, so as to adjust the distance between the transition connection mechanism 5 and the gear reducer body 516 to meet the use requirements. Subsequently, under the action of the first spring piece 504 and the second spring piece 510, corresponding position compensation is carried out on both ends of the connection of the transition connection mechanism 5.
