Embodiment Construction
[0015] The confluent three-way valve of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0016] As shown in the accompanying drawings, a confluent three-way valve includes a valve body 1. Lock caps 20 are provided on both sides and bottom of the valve body 1. A valve core 12 is provided above the valve body 1. The valve core 12 A screw rod 18 is arranged inside, the top of the screw rod 18 is connected with a handwheel 19, a pressure cap 17 is arranged on the top of the valve core 12, and a spring 13 is set on the outer side of the screw rod 18 between the pressure cap 17 and the valve core 12 , the lead screw 18 below the spool 12 is provided with a copper gasket 6, the upper and lower sides of the copper gasket 6 are provided with rubber gaskets 5, and the screw 18 below the copper gasket 6 is provided with a nut 2 , 3.
[0017] A rubber gasket 21 is provided between the valve body 1 and the lock...

The invention relates to a three-way valve, in particular to a converging three-way valve structurally comprising a valve body, wherein lock nuts are arranged on the two sides and bottom part of the valve body; a valve core is arranged at the upper part of the valve body; a screw rod is arranged in the valve core; the top part of the screw rod is connected with a handwheel; a valve cap is arrangedat the top of the valve core; a spring is sleeved on the outer side of the screw rod between the valve cap and the valve core; a copper gasket is arranged on the screw rod at the lower part of the valve core; rubber gaskets are arranged on the upper and the lower sides of the copper gasket; and nuts are arranged on the screw rod at the lower part of the copper gasket. Compared with the prior art,the converging three-way valve of the invention is characterized in that the screw rod is controlled to rotate by the handwheel, and then, the flow direction and flow rate of liquid in the valve bodycan be controlled by driving the copper gasket and the rubber gaskets, thereby achieving the purposes of controlling the temperature of boiler return water and effectively avoiding the condensation corrosion caused by the boiler return water at an over-low temperature; and the converging three-way valve has the advantages of stable flow rate, one-way flow, high converging performance and the like.
Description
technical field [0001] The invention relates to a valve body, in particular to a confluent three-way valve. Background technique [0002] The three-way valve in the prior art has a relatively simple structure, and the control of the water flow is often not stable enough, resulting in a large contrast between the hot and cold water during the process of controlling the exchange of the hot and cold water, thereby causing inconvenience in use. Contents of the invention [0003] The present invention aims at the above deficiencies, and provides a confluent three-way valve, which has the advantages of stable flow, one-way flow, confluent flow, etc., can control the boiler return water temperature, and effectively prevent condensation corrosion caused by too low boiler return water temperature. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A confluent three-way valve, comprising a valve body, lock caps are arranged...
