[0027] The following embodiments further illustrate specific implementations of a variable current splitter according to the present invention. The variable current splitter of the present invention is not limited to the descriptions in the following embodiments.

[0028] Example 1:

[0029] A variable current splitter, such as Figure 1-3 As shown, it includes a throttle valve seat 1, a flow divider head 2 connected to the front end of the throttle valve seat 1, a plurality of output pipes 3 connected to the front end of the flow divider head 2, a throttle valve 4 provided inside the throttle valve seat 1, a pipe connector 5 provided at the rear end of the throttle valve seat 1, the pipe connector 5 and the rear end of the throttle valve seat 1 are fixed by a clamping nut 7, and the rear end of the pipe connector 5 is connected to the input pipe 6.

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

[0031] In one possible implementation, the throttle valve 4 is a five-sided variable throttle valve, which is located in the inner cavity 13. It has five edges on its outer side, and the five edges are distributed and slidably engaged with the corresponding slide rails in the inner cavity 13.

[0032] In one possible implementation, the throttle valve 4 includes a valve body 41, a sealing surface 42 at the front end of the valve body 41, the sealing surface 42 having a conical structure, the front end of which is sealed to the rear end of the flow hole 12, and a valve hole 43 at the center of the throttle valve 4, which is connected to the flow hole 11.

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

[0034] In one possible implementation, the front end of the pipe connector 5 is inserted into the rear end of the inner cavity 13, the outer edge of the pipe connector 5 is attached to the outer end of the rear side of the throttle valve seat 1, the clamping nut 7 is sleeved on the outside of the pipe connector 5, and the clamping nut 7 is threadedly connected to the rear end of the throttle valve seat 1.

[0035] In one possible implementation, a sealing ring is fitted onto the outer rear end of the throttle valve seat 1, and the outer edge of the pipe joint 5 is squeezed to achieve a seal at the connection.

[0036] In one possible implementation, the front end of the pipe connector 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 connector 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 a seal between the sealing surface 42 and the flow hole 12.

[0037] In one possible implementation, by loosening the clamping nut 7, the pipe fitting 5 and the throttle valve 4 can be removed in sequence, and the throttle valve 4 with a suitable orifice diameter can be replaced.

[0038] In one possible implementation, the throttle valve 4 can be replaced with throttle valves 4 of different orifice diameters (valves that control fluid flow by changing the throttle cross section or throttle length) to conveniently provide different variable throttle valve cores to produce different throttle flow values.

[0039] In one possible implementation, the novel variable displacement valve distributor is an accessory device for refrigeration systems that allows for the replacement of throttle valves with different orifice diameters to achieve different flow rates as needed.

[0040] In one possible implementation, the new variable displacement valve diverter is easy to install and remove, and the detachable design of the threaded connection makes the installation and removal process simple and quick, greatly improving the efficiency of maintenance and replacement.

[0041] In one possible implementation, the novel variable displacement valve diverter is reusable, and its threaded, detachable structure allows for the reuse of connectors, avoiding resource waste and environmental pollution. This has a positive impact on both environmental protection and cost control.

[0042] In one possible implementation, a novel variable displacement valve diverter is provided; the tightening force is controllable, and through proper design and processing, the threaded connection can achieve sufficient tightening force during installation, while allowing for easy disassembly.

[0043] In one possible implementation, the novel variable displacement valve diverter has advantages such as simple structure, reliable connection, and strong practicality.

[0044] By adopting the above technical solution:

[0046] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
