The pipe joint 5 is fixed to the rear end of the throttle valve seat 1 by a clamping nut 7, and the rear end of the pipe joint 5 is connected to the input pipe 6.

[0030] In a possible implementation, the throttle valve seat 1 includes an insertion hole 11, a flow hole 12 and an inner cavity 13 arranged in sequence from the front to the back, and the rear end of the diverter head 2 is inserted into the insertion hole 11 and fixed by welding.

A valve hole 43 is opened at the center of the throttle valve 4, and the valve hole 43 is connected to the flow hole 11.

[0033] In a possible implementation manner, a groove 421 is formed on the outer side of the sealing surface 42 , and a sealing ring is formed in the groove 421 for sealing the sealing surface 42 and the flow hole 12 .

[0036] In a possible implementation, the front end of the pipe joint 5 contacts the rear end of the throttle valve 4. When the clamping nut 7 is tightened, as the clamping nut 7 moves forward, the front end of the pipe joint 5 squeezes the throttle valve 4, pushing the throttle valve 4 to slide forward until the sealing ring on the sealing surface 42 is squeezed and deformed, thereby achieving sealing between the sealing surface 42 and the flow hole 12.

This has a positive impact on environmental protection and cost control.

[0042] In a possible implementation, the novel variable throttle valve diverter has a controllable tightening force. Through proper design and processing, the threaded connection can achieve sufficient tightening force during installation and can be easily disassembled during disassembly.

[0043] In a possible implementation, the novel variable throttle valve diverter has the advantages of simple structure, reliable connection, and strong practicality.
