[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1, be a kind of embodiment of voltage stabilizing laminating water supply equipment of the present invention.This voltage stabilizing laminating water supply equipment comprise laminate jar 1, be positioned at the submersible pump 2 that laminates jar, be attached to electric system 3 on the submersible pump, be located at first flange 4, outlet pipe 5 of the opening part that laminates jar, second flange 6, piston 7 and the branch pressure pipe 8 that links to each other with first flange 4.
Second flange 6 and first flange 4 are complementary.Outlet pipe 5 passes the eyelet of second flange 6 and is fixedly linked with second flange 6, and its rear end is stretched 50 and stretched into to laminate in jar 1 and link to each other with submersible pump 2, and its front end 51 exposes outside second flange 6.
As shown in Figure 2, also be provided with an annular sidewall 60 in the outside of second flange 6.This annular sidewall 60 and the second flange outer surface are fixedly linked, and extend protrusion from second flange, 6 outer surface near normal.The annular sidewall 60 and second flange 6 can be structure as a whole and process, also can be welded on the outer surface of second flange 6 through an annular sidewall of peripheral hardware.
Annular sidewall 60 comprises the bottom 61 that links to each other with the second flange outer surface and away from the front end 62 of second flange, front end 62 is provided with the inner edge portion 63 that extends internally.The bottom 61 of this annular sidewall 60 is around the front end 51 of outlet pipe, that is, this annular sidewall 60 is positioned at the periphery of outlet pipe front end 51, surrounds the front end 51 of outlet pipe.
This minute, pressure pipe 8 comprised base plate 80 and the pipeline 81 that links to each other with base plate 80.Through hole 83 as shown in Figure 3, as on base plate 80, also to be provided with centre bore 82 and to center on centre bore, centre bore 82 all communicates with pipeline 81 with through hole 83.In the present embodiment, the number of through hole 83 is 3.The inner edge portion 63 of the edge part of this base plate 80 and annular sidewall front end is fixedly linked.Both connected modes can be that screw thread links to each other, welding, or the like.
Divide the pipeline 81 of pressure pipe to be connected with downstream line, be provided with a circle slot rolling 84 at the outer wall of the pipeline 81 of minute pressure pipe, through this slot rolling 84, the pipeline 81 of branch pressure pipe can adopt the mode that clip docks with downstream line and be fixedly linked.
This base plate 80 and annular sidewall 60 form one and hold air cavity 9, divide the pipeline 81 of pressure pipe to be positioned at outside the appearance air cavity 9, and three through holes 83 communicate with appearance air cavity 9.
Piston 7 is positioned at the inside that holds air cavity 9.This piston 7 comprises bottom 70 and the connecting rod 71 that links to each other with bottom 70.This bottom 70 connects with the front end 51 of outlet pipe, and the end of connecting rod 71 is positioned at the centre bore 82 of branch pressure pipe base plate 80.The purpose of bottom 70 is: under the effect of hydraulic pressure, thereby with the front end 51 of the outlet pipe closed front end 51 of living outlet pipe that connects; Or, separate with the front end 51 of outlet pipe, thereby the aqueous fluid that laminates jar 1 is flowed out through outlet pipe 5.
When voltage stabilizing laminating water supply equipment of the present invention is shut down or is had a power failure; The aqueous fluid shock wave that downstream line produces is at first through dividing pressure pipe decompression 8; Just act on then on the piston 7, piston 7 moves towards the front end 51 of outlet pipe, to the bottom 70 of piston and front end 51 closures of outlet pipe; The bottom that promptly holds air cavity 9 is by piston seal; Thereby, bottling up the aqueous fluid shock wave effectively and move down and rush in and laminate in the jar, protection laminates water pump 2 in jar 1 is avoided the aqueous fluid shock wave with electric system 3 impact failure.When this voltage stabilizing laminating water supply equipment restarts; Laminate a jar interior electric system and a pump working; Laminate and produce certain pressure in jar 1, when this pressure during greater than the hydraulic pressure that holds in the air cavity 9, piston 7 separates with the front end 51 of outlet pipe; Laminate jar 1 an interior aqueous fluid and flow out to downstream line, satisfy the water demand of downstream user toward outlet pipe 5 and branch pressure pipe 8.
At the bottom 70 of piston with divide and also be provided with the helical spring 90 that links to each other with both between the base plate 80 of pressure pipe.This helical spring 90 is around the connecting rod 71 of piston.The purpose of helical spring 90 is to strengthen the active force of piston 7.When voltage stabilizing laminating water supply equipment of the present invention is shut down or is had a power failure, the bottom 70 of piston and front end 51 closures of outlet pipe, helical spring 90 is stretched.When this voltage stabilizing laminating water supply equipment restarts; Laminate a jar interior electric system and a pump working; The reseting elasticity of helical spring 90 stretches the bottom 70 of piston to the direction near the base plate 80 of minute pressure pipe, help front end 51 separation of piston 7 relative outlet pipes.
Above-described only is embodiment of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
