Description
Technical field
The present invention relates to the shuttle valve of under hydraulic pressure, working, more particularly, shuttle valve in a kind of water supply piping system that is installed in building (as single family house, tenement, apartment or office building), so that effectively tap water is supplied with the user in normal time, and the water that stores in the waterworks is suspended between delivery period effectively with roof tank is supplied with the user.
Background technique
The present invention relates to a kind of improved shuttle valve, compare with the shuttle valve that correlation technique is related, tap water that this shuttle valve can more effectively provide the waterworks and the storage water in the water tank are supplied with the user.
Water tank is installed in the roof of inhabited building (as single family house, tenement, apartment or office building) usually.The tap water that the waterworks provides with high pressure is stored in the water tank usually, supplies with the user then.Yet, being stored in the process of water tank at tap water, its high pressure will progressively descend, and until almost nil, just supply water to the user afterwards.Therefore, only in water tank, the water that stores could be supplied with the user under the pressure of water, so just can't effectively the water that stores be supplied with and live in high-rise user, because hydraulic pressure is too low.Though can use suction booster to increase hydraulic pressure in addition, be to use suction booster that its disadvantage is arranged, because its noise is big, and power consumption is also big.
In order to address the above problem, there has been the claimant to propose a kind of utility model (application number is " 20-2002-0025270 ", and title is " a kind of shuttle valve of working ") on August 24th, 2002 under hydraulic pressure.
Below with reference to accompanying drawings and the structure and the problem of above-mentioned utility model be described in conjunction with the present invention.
Fig. 1 has shown the example that shuttle valve is installed to the building water supply piping system according to the present invention; Fig. 2 has shown the perspective exploded view according to the shuttle valve of correlation technique; Fig. 3 has shown the cross-section profile of the shuttle valve among Fig. 2.Though Fig. 1 from explanation of the invention, also can be used for illustrating the shuttle valve according to correlation technique.
According to correlation technique, shuttle valve 50 mainly comprises a sleeve pipe 5; Be fixed on nut up and down 15 on the sleeve pipe 5 with screw; And the switching element 10 of an insertion sleeve pipe 5.Nut 15 is connected respectively to waste pipe 220 and arm 230 up and down, and the water pipe connector 4 of sleeve pipe 5 one sides is connected to water pipe 240.Switching element 10 mainly comprises a main body 6; A rubber bushing 7; A packing ring 8; And connecting bolt 9.Rubber bushing 7 is connected to the upper and lower surface of main body 6 by connecting bolt 9.
Switching element 10 inserts the sleeve pipe 5 with cavity, and moves up and down under hydraulic pressure, so that optionally open and close nut 15 up and down.When tap water normal supply running water pipe 210, tap water is supplied with nut 15 down by arm 230, and promotes to rest on the switching element 10 of the cavity bottom of shuttle valve 50 under hydraulic pressure.Switching element 10 vertically moves up under hydraulic pressure, with the water channel of the upper cap nut 15 of closing the waste pipe 220 that is connected to water tank 200.
Because the switching element that moves up 10 has been closed upper cap nut 15, the tap water of nut 15 can flow to water pipe 240 by water pipe connector 4 so supply with down.Correspondingly, when the user opened the water tap 245 that is connected to water pipe 240, tap water can finally be supplied with the user, and can not lose the pressure that the waterworks produces.
When water tap 245 is closed, the high pressure of tap water will continue pushing switch element 10, and until the water channel of closing upper cap nut 15, thereby the tap water of supplying with running water pipe 210 from the waterworks will be supplied with water tank 200.In case it is a certain amount of that the water in the water tank 200 is filled into, the float in the water tank 200 just will stop gives this water tank for tap water.
When giving running water pipe 210, can use the storage water in the water tank 200 for tap water because water supply is suspended in the waterworks.Leading 245 waters in case the user fetches boiling water, the switching element 10 of closing the water channel of upper cap nut 15 just moves down under the hydraulic pressure of the storage water in water tank 200.The switching element 10 that moves down is closed the water channel of the following nut 15 that is connected to arm 230, thereby can the storage water in the water tank 200 be supplied with water pipe 240 by the waste pipe 220 that is connected to water tank 200, so that the user is by water tap 245 waters.
Yet,, keep a certain amount of surplus water in the sleeve pipe 5 of shuttle valve 50 usually even when suspending for tap water.Because water is a kind of incompressible fluid, so switching element 10 will run into the resistance of the surplus water in the sleeve pipe 5 in the process that moves down.That is to say that touch surplus water in case move down time bottom under the hydraulic pressure of the storage water of switching element 10 in water tank 200, switching element 10 just can't freely be moved downward to the water channel of water pipe 240.
Because a minimum gap is arranged between the internal surface of switching element 10 and sleeve pipe 5, and surplus water will be upwards mobile very lentamente by this gap, so switching element 10 will move down very lentamente.The user must wait for long time leading 245 waters of just fetching boiling water, and need spend the long time because switching element 10 moves down and open the water channel of water pipe connector 4.Experiment showed, after the tap 245 of fetching boiling water, need to wait for that 4 to the 5 minutes storage water in the water tank 200 could flow out water tap 245.Therefore will need spend the long time and could flow out water tap 245 and make troubles owing to storing water to the user.

Mainly comprise the switching element 150 of a sleeve pipe 110 and an insertion sleeve pipe 110 according to the shuttle valve 100 of first embodiment of the invention, with in sleeve pipe 110 upwards, move down.Sleeve pipe 110 1 ends have a waste pipe connector 120, and the other end has one tube connector 130.Waste pipe connector 120 will be connected to the waste pipe 220 that is connected with water tank 200, and a tube connector 130 will be connected to the arm 230 that stretches out from water pipe 210.Sleeve pipe 110 1 sides have a water pipe connector 140, will be connected to the water pipe 240 that is connected with switch valve (as water tap or shower).Waste pipe connector 120, a tube connector 130 and water pipe connector 140 have internal thread on the surface within it, will be connected respectively to waste pipe 220, arm 230 and water pipe 240.In the sleeve pipe 110 cavity is arranged, so that make progress, move down under the hydraulic pressure of the tap water of switching element 150 in water tank 200 and storage water.As shown in Figure 5, stopping device 112 is arranged on the internal surface of sleeve pipe 110, with moving of switching element 150 in the prevention sleeve pipe 110.
As shown in Figure 6, switching element 150 can have cylindrical shape, and a plurality of longitudinal flutings 154 are arranged on its outer surface.
The working principle of shuttle valve of the present invention is as follows.Running water pipe 210 is supplied with the tap water of high force feed in the waterworks, supplies with arm 230 then.The pressure of tap water has quite high pressure because supply with the tap water of arm 230, so will upwards promote to rest on the switching element 150 of sleeve pipe 110 bottoms.Switching element 150 moves up, and till running into stopping device 112, thereby closes the water channel of waste pipe connector 120.The hydraulic pressure of the storage water in the water tank 200 vertically acts on the upper surface of switching element 150, and the hydraulic pressure of the tap water in the tube connector 130 vertically acts on the lower surface of switching element 150.Because the hydraulic pressure of tap water is usually above the hydraulic pressure of the storage water in the water tank 200, so the pressure reduction of water will make switching element 150 maintenances close the water channel of waste pipe connector 120, shown in the part of the A among Fig. 5.When switching element 150 touches stopping device 112 when closing the water channel of waste pipe connector 120, the water channel of the water pipe connector 140 on sleeve pipe 110 sides will be opened.Correspondingly, supply with the tap water of arm 230 and can supply with water pipe 240, tap water is finally supplied with the user so that can open the water tap 245 that is connected to water pipe 240 by water pipe connector 140.As mentioned above, the user can directly and effectively be supplied with the tap water that high pressure provides in the waterworks, and does not have the pressure loss.
When the user did not fetch boiling water leading 245 waters, tap water can't flow to water pipe 240 by arm 230.
Correspondingly, switching element 150 keeps closing the water channel of waste pipe connector 120, can upwards flow to water tank 200 so that supply with the tap water of running water pipe 210, thereby be filled into water tank 200 a certain amount of.
When the waterworks can not be given running water pipe 210 for tap water, (for example suspending under the situation about supplying water), can replace tap water with the storage water in the water tank 200.
Become and be higher than the hydraulic pressure of the lower surface that acts on switching element 150 because act on the hydraulic pressure of storage water of the upper surface of switching element 150, so switching element 150 begins to move down.By the way, even do not supply tap water, also can keep a certain amount of water in the sleeve pipe 110 to a tube connector 130.Correspondingly, during moving down, switching element 150 can allow under the resistance of surplus water and store current direction water pipe connector 140.Yet, because according to the present invention, have a longitudinal fluting 154 on the outer surface of switching element 150 at least, so when switching element 150 moved down, surplus water longitudinally groove 154 upwards flowed.Therefore, switching element 150 can be closed the water channel of a tube connector 130 fast and effectively, and the water channel of reservation water pipe connector 140 is opened.In case switching element 150 is closed the water channel of a tube connector 130, the storage water in the water tank 200 just can flow to sleeve pipe 110, flows to water pipe 240 then.
As mentioned above, compare with correlation technique, the storage water in the water tank 200 can be quicker and be supplied with the user effectively.Fig. 7 has shown the modification to the switching element among Fig. 6.
Switching element 150 can have circumferential groove 154a and 154b and longitudinal fluting 154 on the outer surface of main body 152.
Describe other embodiments of the invention with reference to the accompanying drawings in detail.
