Disclosure of Invention
The invention aims to provide a steady flow water diversion valve and a water diversion device which are convenient to install and detach.
In order to achieve the above object, the present invention has the following technical scheme:
A steady-flow water diversion 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, 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, the axis of the buffer cavity is mutually perpendicular to the axis of the water inlet and the axis of the water outlet, a communication hole is formed between the buffer cavity and the first water outlet channel, and a valve core assembly used for adjusting the opening and closing states of the communication hole is arranged in the valve body.
The steady flow water diversion valve is provided with the independent valve body, the valve body and the valve core can achieve an expected sealing state, when the steady flow water diversion valve is used, only the water inlet of the valve body is connected with the water inlet pipe of the water diversion device, and the water outlet of the valve body is connected with the water diversion pipe of the water diversion device, so that the whole installation and disassembly processes are very simple, convenient and quick, and the sealing connection between pipelines is more labor-saving.
The steady flow water diversion valve is provided with the buffer cavity, and the hot fluid entering from the water inlet pipeline firstly flows slowly through the buffer cavity and then enters the water outlet channel, so that the hot fluid entering the water diversion pipe is ensured not to rush, and the heat exchange efficiency of the hot fluid in each space needing to be warmed is higher.
In the steady flow water diversion valve, the valve core assembly comprises a valve core which is slidably arranged in the buffer cavity, the tail end of the valve core is provided with an outward flange which is in sealing fit with the inner wall of the buffer cavity, the head end of the valve core is provided with a valve head which is matched with the communication hole, a driving unit which is used for driving the valve head to be far away from or block the communication hole is arranged in the valve body at the tail end of the valve core, and a limiting step which is propped against the outer edge of the opening of the communication hole is formed between the valve core and the valve head. The outer diameter of the valve core main body can be reduced by arranging the outward flange in sealing fit with the inner wall of the buffer cavity, so that more buffer space is reserved for the buffer cavity. The limiting step is used for limiting the maximum travel of the valve head.
In the steady flow water diversion valve, a return spring is abutted between the turnup edge and the outer edge of the opening of the communicating hole. The return spring can assist the valve head away from the communication hole.
In the steady flow water diversion valve, a notch for communicating the buffer cavity and the first water outlet channel is formed on the valve head, and the opening of the notch is gradually reduced from one end of the valve head, which faces the communication hole, to one end, which is far away from the communication hole. After the notch is arranged, even if the valve head is accommodated in the communication hole, the hot fluid in the buffer cavity can still enter the first water outlet channel from the notch, and the flow of the hot fluid entering the first water outlet channel is reduced along with the increase of the accommodating depth of the valve head until the flow is zero. Such a valve head configuration is more advantageous for regulating the flow of fluid through the shunt valve than a valve head that is entirely cylindrical.
Preferably, in the steady flow water diversion valve, the notch has a triangular cross section.
In the steady flow water diversion valve, an installation channel communicated with the buffer cavity is formed in the valve body, the driving unit comprises a valve cover which is connected in the installation channel in a threaded mode, a valve rod is abutted between the valve cover and the valve core, and a sealing element is arranged between the valve cover and the valve body.
In the steady flow water diversion valve, a first guide groove for accommodating the valve rod is arranged in the valve core. The setting of first guide way can avoid the case to block under the extrusion of valve rod in the cushion chamber, ensures sliding fit's patency between case and the cushion chamber.

In the steady flow water diversion valve, the buffer cavity is communicated with the first water outlet channel through a buffer channel which is obliquely arranged upwards. The hot fluid entering the buffer cavity gradually flows into the buffer channel and finally enters the first water outlet channel, so that the further steady flow of the hot fluid is realized.
The water separator comprises a water inlet pipe, wherein the water inlet pipe is provided with a plurality of short joints, each short joint is connected with a water separation pipe through the steady flow water separation valve, the water inlet end of the steady flow water separation valve is provided with a first connector for fixing the short joint, and the water outlet end of the steady flow water separation valve is provided with a second connector for fixing the water separation pipe.
The water diversion pipe of the water diversion device is separated from the water inlet pipe, and only the short joint for connecting the water diversion pipe is arranged on the water inlet pipe, so that the water diversion device is convenient for installing the steady flow water diversion valve, greatly reduces the whole volume of the water diversion device, and is convenient for respectively maintaining or replacing the water inlet pipe and the water diversion pipe.
In the water separator, the first connector comprises a first inner connecting sleeve and a first outer connecting sleeve which are coaxially arranged, and a second water inlet channel is formed in the center of the first inner connecting sleeve; the outer wall of the first inner connecting sleeve is provided with a flexible extrusion sleeve, and a short joint installation space is formed between the flexible extrusion sleeve and the first inner connecting sleeve;
The second connector comprises a second inner connecting sleeve and a second outer connecting sleeve fixedly arranged on the periphery of the second inner connecting sleeve, a second water outlet channel is formed in the center of the second inner connecting sleeve, a water diversion pipe installation space is formed between the second outer connecting sleeve and the second inner connecting sleeve, the second inner connecting sleeve is in threaded connection with the valve body, and the second outer connecting sleeve is in threaded connection with the water diversion pipe.
Because the fluid flowing from the water inlet pipe into the first water inlet channel is faster and the flow is larger, a flexible extrusion sleeve is required to be arranged in the first connecting head, the flexible extrusion sleeve is circumferentially extruded by the first external connecting sleeve and the valve body which are in threaded connection, and the short connecting head is ensured to be tightly connected with the steady flow water diversion valve. The fluid flowing out from the first water outlet channel has slower flow speed and smaller flow, so that the second inner connecting sleeve is in threaded connection with the valve body and the second outer connecting sleeve is in threaded connection with the water diversion pipe, and the steady flow water diversion valve can be tightly connected with the water diversion pipe.
