Description

Technical Field

[0001] The utility model relates to the field of bellows connection, in particular to a bellows connection device with a sealing function. Background Art

[0002] A bellows connection device with a sealing function has a wide range of applications and is of great importance in the field of engineering technology. As a commonly used piping component, bellows plays a vital role in liquid and gas transmission systems due to its excellent flexibility and corrosion resistance. However, bellows connections are often prone to leakage, which not only affects the normal operation of the system but also may cause environmental pollution and safety hazards.

[0003] The existing bellows connection method relies on sealing elements such as rubber sealing rings or metal clamps to connect the two sections of bellows. However, since the impact force on the bellows connection is generally large, the existing connection method is prone to leakage due to impact during connection, which is relatively inconvenient.

[0004] Therefore, a bellows connection device with a sealing function that can improve the impact resistance of the bellows connection and prevent leakage during the bellows connection has been developed. Utility Model Content

[0005] In order to overcome the disadvantages that the impact force on the bellows connection is generally large, the existing connection method is prone to leakage due to impact during connection, which is relatively inconvenient, the utility model provides a bellows connection device with a sealing function that can improve the impact resistance of the bellows connection and prevent leakage during bellows connection.

[0006] The technical solution of the utility model is: a bellows connection device with a sealing function, comprising a pipeline, an inner bellows, a sealing ring, a fixing frame, a screw and a mounting plate, the front and rear sides of the pipeline are connected to the inner bellows, the ends of the sealing ring away from each other are connected to the fixing frame, the inner sides of the fixing frames are connected to the sealing rings, the outer sides of the front and rear ends of the pipeline are connected to the mounting plates, a plurality of screws are threadedly connected to the mounting plates, and the fixing frames are slidably engaged with adjacent screws.

[0007] Furthermore, the pipe is made of stainless steel.

[0008] Furthermore, a limiting nut is threadedly provided on the fixing frame.

[0009] Furthermore, a thread is provided on the inner side of the fixing frame.

[0010] Furthermore, the sealing ring is made of rubber.

[0011] Furthermore, it also includes a flow velocity meter and a display screen. The top of the pipeline is connected to the flow velocity meter, the upper side of the pipeline is connected to the display screen, and the display screen is connected to the flow velocity meter.

[0012] The beneficial effects are: the utility model strengthens the connectivity between the inner bellows and the bellows through the sealing gasket, and performs a small extension and contraction through the inner bellows to relieve and disperse the impact in the pipeline, while performing a part of the temperature compensation, and resisting the impact of water flow through the pipe, thereby achieving the effect of improving the impact resistance of the bellows connection, preventing leakage when the bellows are connected, and having a more convenient sealing effect.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A bellows connection device with sealing function, such as Figure 1 and Figure 2 As shown, it includes a pipe 1, an inner bellows 2, a sealing ring 3, a fixing frame 4, a screw 5, a mounting plate 6, a flow rate meter 7 and a display screen 8. The inner bellows 2 are connected to the front and back sides of the pipe 1. The pipe 1 is made of stainless steel. The inner bellows 2 are connected to the fixing frame 4 at one end away from each other. The sealing ring 3 is made of rubber. The fixing frame 4 is threaded with a limit nut to limit the telescopic distance of the fixing frame 4. The inner side of the fixing frame 4 is connected to the sealing ring 3. The inner side of the fixing frame 4 is provided with a thread for easy docking. The outer sides of the front and back of the pipe 1 are connected to the mounting plate 6. A plurality of screws 5 are threadedly connected to the mounting plate 6. The fixing frame 4 is slidably connected to the adjacent screws 5. The top of the pipe 1 is connected to the flow rate meter 7. The upper side of the pipe 1 is connected to the display screen 8, and the display screen 8 is connected to the flow rate meter 7.

[0018] When using the present invention, first move the device to the connection position of the bellows, then dock the two ends of the bellows to be connected with the fixing frame 4 respectively, and then tighten the inner bellows 2 to be connected on the fixing frame 4 through the threads on the fixing frame 4. The sealing between the bellows and the fixing frame 4 can be strengthened by the sealing ring 3. Then the bellows can be connected to the equipment for use. When the bellows is used, the fixing frame 4 can slide on the screw 5, so that the inner bellows 2 can be slightly stretched and contracted, alleviating and dispersing the impact in the pipe 1, and at the same time performing part of the temperature compensation to improve the service life of the bellows. At the same time, because the pipe 1 is made of stainless steel metal material, it can effectively resist the impact of water flow, thereby improving the impact resistance of the bellows connection, preventing leakage when the bellows is connected, and having a more convenient sealing function. When in use, the liquid flow rate in the pipe 1 can be monitored by the flow rate meter 7, and the monitored flow rate result is displayed on the display screen 8, which is convenient for the operator to observe the flow rate. When the flow rate in the corrugation is abnormal, it is convenient to deal with it in time.
