Under existing technical conditions, existing hemodialysis water making device can not start emergent device when emergency occurs, if system occur equipment fault cause cannot normal water supply time, then ensureing to keep in repair equipment when product water can be provided simultaneously, cannot will cause serious consequence.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, there is provided a kind of and can be used for emergency processing and the hemodialysis water making device Emergency water supply conveyer device that emergency conveyance is convenient and swift, emergency conveyance efficiency is high, this device can when causing hemodialysis apparatus cannot provide dialysis solution because of any plant failure of two-stage filter or two-stage filter preorder, for patient's normal water supply, avoid occurring accident in default of dialysis solution, simultaneously for buffer time striven for by maintenance of equipment.
Object of the present invention is achieved through the following technical solutions: a kind of hemodialysis water making device Emergency water supply conveyer device, it comprises filter transfer pipeline, secondary is met an urgent need transfer pipeline, one-level Contingency supply pipeline, product water output pipe, wherein said filter transfer pipeline IP filter and electromagnetic valve, described one-level Contingency supply pipeline is provided with single filter system and valve F, single filter system comprises valve B, water pump A and first level filtering device, water pump A is other is parallel with valve C, valve C two ends are connected to water pump A by water pipe, described secondary transfer pipeline of meeting an urgent need comprises valve E, cascade filtration system and check valve, cascade filtration system comprises water pump B, valve D, two-stage filter, water pump B is other is parallel with valve D, valve D two ends are connected to water pump A by water pipe, product water output pipe is provided with valve G, one-level Contingency supply pipeline, secondary transfer pipeline input of meeting an urgent need is connected to filter transfer pipeline, one-level Contingency supply pipeline, secondary transfer pipeline outfan of meeting an urgent need is connected to product water output pipe.
Described one-level Contingency supply pipeline, the secondary pipeline of meeting an urgent need between transfer pipeline and valve G are provided with a Pressure gauge.
The present invention has the following advantages: the present invention is when emergency occurs, by enabling this device Emergency water supply, ensure dialysis solution stable output, it has, and emergency conveyance is convenient and swift, emergency conveyance efficiency is high and current can be avoided to be truncated to such an extent as to affect the advantage of follow-up use.
Accompanying drawing explanation
Fig. 1 is kind of a structural representation for hemodialysis water making device Emergency water supply conveyer device.
In figure, 1-secondary is met an urgent need transfer pipeline, 2-valve E, 3-one-level Contingency supply pipeline, 4-valve F, 5-filter, 6-filter transfer pipeline, 7-electromagnetic valve, 8-valve B, 9-valve B, 10-water pump A, 11-valve C, 12-first level filtering device, 13-water pump B, 14-valve D, 15-two-stage filter, 16-check valve, 17-Pressure gauge, 18-product water output pipe, 19-valve G.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
Fig. 1 is a kind of hemodialysis water making device Emergency water supply conveyer device, it comprises filter transfer pipeline 6, secondary is met an urgent need transfer pipeline 1, one-level Contingency supply pipeline 3, product water output pipe 18, wherein said filter transfer pipeline 6 IP filter 5 and electromagnetic valve 7, described one-level Contingency supply pipeline 3 is provided with single filter system and valve F4, single filter system comprises valve B9, water pump A10 and first level filtering device 12, water pump A10 is other is parallel with valve C11, valve C11 two ends are connected to water pump A10 by water pipe, described secondary transfer pipeline 1 of meeting an urgent need comprises valve E2, cascade filtration system and check valve 16, cascade filtration system comprises water pump B13 and two-stage filter 15, water pump B13 is other is parallel with valve D14, valve D14 two ends are connected to water pump A10 by water pipe, product water output pipe 18 is provided with valve G19, one-level Contingency supply pipeline 3, secondary transfer pipeline 1 input of meeting an urgent need is connected to filter transfer pipeline 6, one-level Contingency supply pipeline 3, secondary transfer pipeline 1 outfan of meeting an urgent need is connected to product water output pipe 18, described one-level Contingency supply pipeline 3, the secondary pipeline of meeting an urgent need between transfer pipeline 1 and valve G19 is provided with a Pressure gauge 17.
