The product provided by the utility model has good sealing effect; the product is light, greatly saving the cost of raw materials; the wedge cap will not fall off before installation, and the installation is convenient.

[0003] The existing three-way joints do not have a flow regulation function. Generally, when in use, three-way joints often only have a diversion effect, and their inner diameter is often fixed. When the flow rate needs to be adjusted, it needs to be adjusted at the main valve. The flow control is not precise enough, and it is not convenient to use or to assemble and disassemble. Generally, three-way joints are connected to the connecting pipes through threads. When assembling and disassembling, tools are needed to disassemble and assemble them. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of assembly and disassembly. In order to solve the above-mentioned problems, we propose a three-way joint with adjustable flow. Utility Model Content
