Abstract
The invention discloses a water pressure detection device of a water production device for hemodialysis. The water pressure detection device comprises a secondary filtering device (1), a pressure gauge (2), a product water conveying pipeline (4), a constant pressure pipeline (5) and a controller (9); the pressure gauge (2) is arranged on a pipeline which is arranged between the secondary filtering device (1) and the product water conveying pipeline (4); the constant pressure pipeline (5) is provided with a circulating high-pressure detection switch (6) and an automatic pressure regulating valve (7); a valve (8) is arranged beside the automatic pressure regulating valve (7); each end of the valve (8) is communicated with the corresponding end of the automatic pressure regulating valve (7) through a water pipe. According to the water pressure detection device of the water production device for the hemodialysis, the water pressure output from the secondary filtering device is checked through the pressure gauge, the set pressure in the constant pressure pipeline is detected through the circulating high-pressure detection switch, the structure is simple, and the response is rapid.
Description
Technical field
The present invention relates to haemodialysis water making device, particularly a kind of haemodialysis water making device device for detecting water pressure.
Background technology
Haemodialysis water making device is the water treatment facilities specially needed for haemodialysis, and patient passes through the semi-permeable diaphragm of haemodialyser or filter for blood dialysis, contacts weekly the water more than 300L possibly.And the people that healthy, the water taken in weekly rarely exceeds 12 liters, increases nearly 30 times with the Exposure of water, therefore, should control and monitor water quality, to avoid known or that estimation is harmful material excessive.That prepares dislysate usually all will through certain process with water, and water quality reaches the requirement of regulation.The equipment performance of water treatment system how, depends on the water quality of former water and the function of whole system, sees that can it prepare and continuous production goes out qualified process water.
Under existing technical conditions, existing hemodialysis apparatus is getting rid of the possibility of secondary pollution again after pressure regulation, filtration by twoport press packet, again hydraulic pressure is not processed, if preceding apparatus causes water pressure fluctuations, scope is larger, the hydraulic pressure that patient can bear may be exceeded, affect patient and use.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, there is provided a kind of structure simple, respond haemodialysis water making device device for detecting water pressure fast, this device can detect that two-stage filter exports the size of hydraulic pressure, and when exporting hydraulic pressure and being excessive by constant voltage pipeline automatically unloading, to ensure the water pressure invariableness in product water transfer pipeline.
Object of the present invention is achieved through the following technical solutions: a kind of haemodialysis water making device device for detecting water pressure, it comprises two-stage filter, tensimeter, product water transfer pipeline, constant voltage pipeline and controller, wherein tensimeter is arranged on the pipeline between two-stage filter and product water transfer pipeline, constant voltage pipeline is provided with circulation high pressure detector switch, automatic pressure regulator, be parallel with valve on automatic pressure regulator side, valve two ends are communicated with automatic pressure regulator two ends by water pipe.
Described valve is solenoid valve, and valve, circulation high pressure detector switch are electrically connected with controller.
Described product water transfer pipeline is provided with valve A.
The present invention has the following advantages: the present invention checks by tensimeter the hydraulic pressure that two-stage filter exports, and detect the hydraulic pressure in constant voltage pipeline by circulation high pressure detector switch, and when the hydraulic pressure that two-stage filter exports exceedes setting value, by automatic pressure regulator release, have and respond quick, the simple advantage of structure.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of haemodialysis water making device device for detecting water pressure.
In figure, 1-two-stage filter, 2-tensimeter, 3-valve A, 4-product water transfer pipeline, 5-constant voltage pipeline, 6-circulation high pressure detector switch, 7-automatic pressure regulator, 8-valve, 9-controller.
Embodiment
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:
As shown in Figure 1, a kind of haemodialysis water making device device for detecting water pressure, it comprises two-stage filter 1, tensimeter 2, product water transfer pipeline 4, constant voltage pipeline 5 and controller 9, in the present embodiment, described tensimeter 2 is arranged on the pipeline between two-stage filter 1 and product water transfer pipeline 4, described product water transfer pipeline 4 is provided with valve A3, described constant voltage pipeline 5 is provided with circulation high pressure detector switch 6, automatic pressure regulator 7, valve 8 is parallel with on automatic pressure regulator 7 side, valve 8 two ends are communicated with automatic pressure regulator 7 two ends by water pipe, in the present embodiment, described valve 8 is solenoid valves, valve 8, circulation high pressure detector switch 6 is electrically connected with controller 9.
The course of work of the present invention is as follows: under normal operation, valve B6 is in normally off, product water after filtering flows out from two-stage filter 1, tensimeter 2 can check the size exporting hydraulic pressure, product water enters dialysis machine through product water transfer pipeline 4, when the valve A3 closedown on product water transfer pipeline 4 or dialysis machine water, product current flow into constant voltage pipeline 5 by automatic pressure regulator 7 pressure release, reduce the hydraulic pressure flowing to the transfer pipeline 3 of dialysis machine, circulation high pressure detector switch 6 can detect the hydraulic pressure size flowing into constant voltage pipeline 5, releasing pressure automatically when if hydraulic pressure exceedes the maximum pressure that automatic pressure regulator 7 can bear, thus ensure that the hydraulic pressure of product water transfer pipeline 3 conveying is always the value of setting.
