Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As Fig. 1 and Fig. 2, shown in Figure 3, the utility model preferred embodiment one comprises shell 1, water pipe 2, intake pipe 3, waste pipe 4 and two the valve block node devices 51,52 that are used to its inner parts that protection is provided.Wherein, two valve block node device 51,52 structures are identical, and valve block node device 51 is located on the water pipe 2, and valve block node device 52 is located on the waste pipe 4.
First end of water pipe 2 is water-supplying mouth 21, extends the outside of shell 1, is used for being connected with water supply installation.First end of intake pipe 3 extends the outside of shell 1 as water intake 31, is used for and needs the water device to be connected, and second end of water pipe 2 and second end of intake pipe 3 connect as one.First end of waste pipe 4 extends the outside of shell 1 as drain opening 41, is used for being connected with the draining reception unit, and its second end is connected in intake pipe 3.
As shown in Figure 2, valve block node device 51 or valve block node device 52 comprise valve body 500, valve block 503 and seat board 501, seat board 504.The inside of valve body 500 has a cavity 50.Seat board 504 is located at the feed-water end of cavity 50, and with the axis normal of cavity 50.Seat board 501 is located at the waterexit end of cavity 50, and with the axis normal of cavity 50.Water inlet 506 is positioned at seat board 504 center regions of the feed-water end of cavity 50.Osculum 502 is positioned at the core of seat board 501 of the waterexit end of cavity 50.Valve block 503 is located in the cavity 50 movably along the direction of current in the cavity 50, and valve block 503 is greater than water inlet 506.In other embodiments, if no seat board 504, the joint of cavity 50 and water pipe 2 can be used as water inlet 506.
For fear of valve block 503 unnecessary upset takes place, the cavity 50 of this preferred embodiment one is highly shorter, and restriction valve block 503 is movable in less space.Preferably, the ratio of the distance between the diameter of valve block 503 and water inlet 506 and the osculum 502 is 1:2, and for example the diameter of valve block 503 is 1cm, and the distance between water inlet 506 and the osculum 502 is 2cm.And when using, valve block node device 51,52 is vertically placed, and as shown in Figure 1, seat board 504 is positioned at the below, and seat board 501 is positioned at the top, and therefore, in valve block node device 51,52, the direction of current all is vertically to go up current downflow.
In this preferred embodiment one, cavity 50 is cylindrical, valve block 503 is in the form of annular discs, as shown in Figure 3, the both ends of the surface center region of valve block 503 is outwards level and smooth outstanding, formation is positioned at the projection 5031 of valve block 503 upper-end surfaces and is positioned at the projection 5032 of lower end surface, is positioned at lower end surface level and smooth protruding 5032 corresponding with water inlet 506 of valve block 503.Generally speaking, valve block 503 is the UFO-like disk of thick middle, thin edge.Valve degree of closing can be guaranteed like this, sensitivity can be guaranteed to open and close again.Under action of gravity, if the hydraulic pressure of valve block 503 upper-end surfaces greater than the hydraulic pressure of its lower end surface, 5032 of projectioies stretch in the water inlet 506, realize sealing.In order to increase sealing effect, the edge of water inlet 506 is provided with and is used for the rubber seal 505 that 503 sealings contact with valve block.
The osculum 502 that is positioned on the seat board 501 is Mi Zixing, and the upper-end surface of valve block 503 has projection 5031, even the pressure of the hydraulic pressure in the water pipe 2 in the intake pipe 3, also be that pressure reduction is when big, valve block 503 can not cover whole osculum 502 yet, and current still can freely pass through from osculum 502.
In this preferred embodiment one, valve block 503 is 1.5-1.8 with the proportion of water, can utilize the gravity of valve block 503 like this, makes it at hydraulic pressure hour, falls to water inlet 506, prevents that water from flowing.More preferably, valve block 503 is corrosion resistant metal, alloy or high molecular polymer material, as hard PVC, chlorinated polynvinyl chloride (CPVC), fluorine rubber, magnesium alloy etc.
The working principle of this preferred embodiment one is as follows:
The water supply state, when water intake 31 hydraulic pressure are lower than water-supplying mouth 21 hydraulic pressure (negative pressure), and all less than drain opening 41 hydraulic pressure (malleation), float automatically at the valve block 503 of differential water pressures effect lower valve node device 51, its projection 5032 is left the water inlet 506 of valve block node device 51; The valve block 503 of valve block node device 52 closes, and its projection 5032 is inserted in the water inlet 506 of valve block node device 52, and open in the water supply direction water route, realizes the automatic water-supply of water pipe 2 to intake pipe 3.
Hull-borne, when water intake 31 hydraulic pressure increase gradually, water intake 31 hydraulic pressure are greater than water-supplying mouth 21 hydraulic pressure (negative pressure), close automatically at the valve block 503 of differential water pressures effect lower valve node device 51, stop to supply water.When water intake 31 hydraulic pressure continuation increase, water intake 31 hydraulic pressure are greater than drain opening 41 hydraulic pressure (malleation), and valve block node device 51 keeps closing, and the valve block 503 of valve block node device 52 floats automatically, realizes automatic draining.In like manner, also can finish automatically to the water supply state by hull-borne.
Therefore this preferred embodiment one can realize that the automatic selection of water supply state or hull-borne is also automaticallyed switch along with the reducing or increase of water intake hydraulic pressure, and reaches initiatively to supply water or drain function initiatively.
The valve block node device 51,52 of the utility model preferred embodiment one shown in Figure 1 is when using, should be in vertical state, limited application area, Given this, the utility model also provides preferred embodiment two, as shown in Figure 4, the inwall of cavity 50 is provided with the guiding groove 507 that distributes along water (flow) direction in the cavity 50, the edge of valve block 503 is provided with projection 508, projection 508 embeds in the guiding groove 507, when the pressure reduction of the both ends of the surface of valve block 503 existed, valve block 503 can steadily move in cavity 50 along guiding groove 507.
To sum up, the utility model can be obtained following advantage:
The density of material that the valve block of valve block node device adopts is slightly larger than water, relies on self gravitation and upper and lower surface water pressure difference thereof to realize opening automatically or auto-closing fully, compares control accuracy with spring valve plate and improves greatly; Simultaneously, compare, overcome shortcomings such as Passive Control and control action hysteresis with manual control valve or solenoid valve.
Whole alloy or the polymeric material of adopting of valve block or the utility model made, and be corrosion-resistant, reduced replacement cost.
Whole alloy or the polymeric material of adopting of valve block or the utility model made, and prevents from water body is polluted.
The utility model preferably adopts the heating rate material of passing at the low, as: titanium alloy etc., can guarantee under low temperature environment not by bursting by freezing.
But valve block is designed to the free floating valve block, is convenient for changing, and according to the difference of pipeline inner fluid, changes the valve block of different model during work, reaches under the prerequisite that control accuracy does not reduce the purpose of multi-purpose valve.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
