Disclosure of Invention
The invention aims to provide a steady flow water dividing valve and a water divider which are convenient to install and disassemble.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a steady flow shunt valve comprises a valve body, wherein a first water inlet channel with a water inlet and a first water outlet channel with a water outlet are formed in the valve body, and the water inlet and the water outlet are positioned on the same axis; a buffer cavity communicated with the first water inlet channel and the first water outlet channel is formed in the valve body, and the axis of the buffer cavity is vertical to the axes of the water inlet and the water outlet; a communicating hole is formed between the buffer cavity and the first water outlet channel, and a valve core assembly for adjusting the opening and closing state of the communicating hole is arranged in the valve body.
The steady flow shunt valve provided by the invention is provided with the independent valve body, the valve body and the valve core can reach the expected sealing state, when the steady flow shunt valve is used, only the water inlet of the valve body is connected with the water inlet pipe of the water distributor, and the water outlet of the valve body is connected with the shunt pipe of the water distributor, so that the whole installation and disassembly processes are very simple, convenient and rapid, and the sealing connection between the pipelines is more labor-saving.
The flow stabilizing water dividing valve is provided with the buffer cavity, and hot fluid entering from the water inlet pipeline firstly flows through the buffer cavity in a buffering mode and then enters the water outlet channel, so that the hot fluid entering the water dividing pipe is prevented from rushing rapidly, and the heat exchange efficiency of the hot fluid in each space needing to be heated is higher.

The outer diameter of the valve core main body can be reduced by arranging the outward flange to be in sealing fit with the inner wall of the buffer cavity, and more buffer space is reserved for the buffer cavity. The limiting step is used for limiting the maximum stroke of the valve head movement.

The hot fluid entering the buffer cavity gradually flows into the buffer channel and finally enters the first water outlet channel, so that the hot fluid is further stabilized.
The water separator comprises a water inlet pipe, wherein a plurality of short joints are arranged on the water inlet pipe, and each short joint is connected with a water separation pipe through a steady flow water separation valve; the water inlet end of the steady flow shunt valve is provided with a first connector for fixing the short connector, and the water outlet end of the steady flow shunt valve is provided with a second connector for fixing the shunt pipe.
