Abstract
The invention provides a three-way valve. The three-way valve comprises a valve body. Three valve ports are symmetrically formed in the valve body. The axes of the three valve ports are located on the same plane. A steering assembly is further arranged in the valve body. Three flow guiding tubes corresponding to the three valve ports are formed in the steering assembly. The three flow guiding tubes are communicated with one another. The steering assembly is connected with the valve body in a rotatable mode. Limiting blocks limiting the rotation angle of the steering assembly are further arranged in the valve body. Each limiting block is fixed to one side face of the corresponding valve port. The limiting blocks are arc. The radian between the wall surfaces of every two adjacent valve ports is alpha. The radian of each limiting block is alpha/2. The three-way valve solves the technological problem that in the prior art, all the three valve ports of an existing three-way valve cannot be closed at the same time.
Description
Technical field
The present invention relates to a kind of three-way valve, belong to valve field.
Background technique
Three-way valve valve body has three mouths, and one enters scene 2, (left side is entered, right and under go out) different with common valve have an outlet bottom being, when inner spool is during at diverse location, outlet is different, and if spool is when the bottom, left and right communicates, if spool is when the top, right outlet is plugged, and left and end opening leads to.Because Zuo Kou and right mouth be not on a horizontal line.When height adds emergency separation, valve closing, feedwater by-passing.Three-way valve is divided into converging valve and diverter valve by the fluid mode of action, and converging valve has two entrances, behind interflow, from an outlet, flows out.Diverter valve has a fluid input, after shunting, by two fluid outputs, is flowed out.. three-way valve has two spools and valve seat construction and double seated valve similar, but in three-way valve, when the circulation area of spool and valve base chamber increases, and the circulation area minimizing of another spool and valve base chamber.And the circulation area of two spools and valve base chamber is to increase or reduce in double seated valve simultaneously simultaneously.The gas of three-way valve is opened and air to close, can only be by selecting positive interaction and the reaction of actuator to realize, and in double seated valve, open can be directly by instead filling valve body or spool to realize with valve seat with air to close for gas.When three-way valve is used for needing fluid to carry out the control system of proportioning, because it can contemporaryly replace a gas to open control valve and an air to close control valve, therefore can reduces installation cost and reduce installing space.Three-way valve also can be used for the place of Bypass Control, for example a road fluid need to pass through heat exchanger heat exchange, another road fluid does not need, through heat exchanger heat exchange, to adopt diversion three-way valve in the time of before three-way valve is arranged on heat exchanger, adopts converging three-way valve in the time of after three-way valve is arranged on heat exchanger.Because the liquid flowing through in the three-way valve being arranged on before heat exchanger has uniform temp, so leakage rate is less, and being arranged on the liquid flowing through in the three-way valve after heat exchanger has different temperatures, and different to the degrees of expansion of spool and valve seat, therefore, leakage rate is larger.
Triple valve and common valve be the most obvious difference in appearance, is exactly many runner mouths.
Traditional three-way valve cannot be realized whole sealings of three through holes, is not easy to control and the operation of convection cell.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical problem that three valve ports of three-way valve in prior art cannot Close All, a kind of novel three-way valve is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of three-way valve, comprise valve body, symmetrically on valve body be provided with three valve ports, the axis of three valve ports at grade, in described valve body, be also provided with steering assembly, on described steering assembly, be provided with three honeycomb ducts corresponding with described valve port, described three honeycomb ducts interconnect, and described steering assembly and valve body are rotationally connected.
As further innovation of the present invention, in described valve body, be also provided with the limiting stopper of restriction steering assembly rotation angle, described limiting stopper is fixed on one of them side of each valve port.
As further innovation of the present invention, described limiting stopper is arc, and the radian between the wall of adjacent two valve ports is α, and the radian of described limiting stopper is α/2.
As further innovation of the present invention, one end that described valve port is positioned at valve interior wall is also provided with seal ring.
As further innovation of the present invention, described steering assembly surface is coated with rubber.
The invention has the beneficial effects as follows:
This valve, by the cooperation of a three-dimensional connecting tube and limiting stopper, is closed when realizing three pipelines of three-way valve, and registration.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is generalized section of the present invention.
Wherein: 1 is valve body, 2 is valve port, and 3 is limiting stopper, and 4 is seal ring, and 5 is honeycomb duct, and 6 is steering shaft.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of three-way valve of the present invention, comprise valve body 1, symmetrically on valve body 1 be provided with three valve ports 2, the axis of three valve ports 2 at grade, is also provided with steering assembly in described valve body 1, is provided with three honeycomb ducts 5 corresponding with described valve port 2 on described steering assembly, described three honeycomb ducts 5 interconnect, and described steering assembly and valve body 1 are rotationally connected.
As further innovation of the present invention, in described valve body 1, be also provided with the limiting stopper 3 of restriction steering assembly rotation angle, described limiting stopper 3 is fixed on one of them side of each valve port 2.
As further innovation of the present invention, described limiting stopper 3 is arc, and the radian between the wall of adjacent two valve ports 2 is α, and the radian of described limiting stopper 3 is α/2.
By this kind of device, by rotating steering shaft 6, rotate steering assembly, three-dimensional connecting tube and limiting stopper 3 reach matched position, thereby close when having realized three pipelines of three-way valve, and registration.
As further innovation of the present invention, one end that described valve port 2 is positioned at valve body 1 inwall is also provided with seal ring 4.
As further innovation of the present invention, described steering assembly surface is coated with rubber; All further increased sealability.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
