Description
Technical field
The present invention relates to hemodialysis apparatus water supply field, particularly a kind of hemodialysis water making device constant pressure water supply dress
Put.
Background technology
Hemodialysis water making device is exclusively for the water treatment facilities needed for hemodialysis, and patient passes through hemodialyzer
Or the semipermeable membrane of filter for blood dialysis, the water more than 300l may be contacted weekly.And a healthy people, take in weekly
Water rarely exceeds 12 liters, increases nearly 30 times with the exposure of water, therefore, should control and monitor water quality, to avoid known or to estimate
Material in respect of evil is excessive.That prepares dialysis solution generally will be through certain process with water, and water quality reaches the requirement of regulation.Water
The equipment performance of processing system how, the water quality depending on raw water and the function of whole system, sees that can it prepare and continue
Produce qualified process water.
Under existing technical conditions, existing hemodialysis water making device is leading to after pressure regulation, prefiltration again
Cross double-stage reverse osmosis to filter, again hydraulic pressure is not processed, scope is larger if preceding apparatus cause water pressure fluctuations, may surpass
Go out the hydraulic pressure that hemo system can bear, impact uses.
Content of the invention
It is an object of the invention to overcoming the shortcoming of prior art, provide the blood that a kind of structure is simple, pressure of supply water is stable
Mechanism wetting system stabilized voltage device thoroughly, this device can pass through the hydraulic pressure of automatic Regulation valve regulation constant voltage pipeline, makes to be transported in
The hydraulic pressure of hemo system keeps constant.
The purpose of the present invention is achieved through the following technical solutions: a kind of hemodialysis water making device constant pressure water supply dress
Put, it includes two-stage filter, product water transfer pipeline and voltage stabilizing pipeline, wherein product water transfer pipeline is provided with valve a,
Voltage stabilizing pipeline is provided with valve b and automatic pressure regulator, according to water (flow) direction, the flat perseverance of two-stage filter, automatic pressure regulator, intelligence
Water tank passes sequentially through water pipe connection, and product water transfer pipeline is arranged at the pipeline between two-stage filter and automatic pressure regulator
On, it is parallel with valve b by automatic pressure regulator, valve b two ends are connected with automatic pressure regulator two ends by water pipe.
Pipeline between the described pipeline at valve b place and product water transfer pipeline is provided with circulation high pressure detection and opens
Close.
The invention has the advantages that the present invention passes through the hydraulic pressure of automatic Regulation valve regulation constant voltage pipeline, make to be transported in blood
The hydraulic pressure of machine keeps constant thoroughly, it is to avoid the variation in water pressure that front and continued equipment leads to brings harmful effect to hemo system, and this device has
Structure is simple, response quickly and the stable advantage of pressure of supply water.
Brief description
Fig. 1 is a kind of structural representation of hemodialysis water making device constant pressure water supply equipment.
In figure, 1- two-stage filter, 2- valve a, 3- product water transfer pipeline, 4- circulates high pressure detection switch, and 5- is certainly
Dynamic pressure regulator valve, 6- valve b, 7- voltage stabilizing pipeline, 8- intelligently flat perseverance water tank.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to described below:
As shown in figure 1, a kind of hemodialysis water making device constant pressure water supply equipment, it includes two-stage filter 1, product
Water transfer pipeline 3 and voltage stabilizing pipeline 7, wherein product water transfer pipeline 3 are provided with valve a2, and voltage stabilizing pipeline 7 is provided with valve b6
With automatic pressure regulator 5, according to water (flow) direction, two-stage filter 1, automatic pressure regulator 5, intelligence flat perseverance water tank 8 pass sequentially through water
Pipe connects, and product water transfer pipeline 3 is arranged on the pipeline between two-stage filter 1 and automatic pressure regulator 5, adjust automatic
It is parallel with valve b6, valve b6 two ends are connected with automatic pressure regulator 5 two ends by water pipe, in the present embodiment, described by pressure valve 5
Pipeline between the pipeline at valve b6 place and product water transfer pipeline 3 is provided with circulation high pressure detection switch 4.
The work process of the present invention is as follows: under normal operation, valve b6 is in normally off, the product after filtering
Product water flows out from two-stage filter 1, is conveyed into hemo system through product water transfer pipeline 3, when hydraulic pressure is higher than to set pressure
During value, part current flow into constant voltage pipeline 7, to reduce the hydraulic pressure in product water transfer pipeline 3, flow into the product in constant voltage pipeline 7
Product water enters through automatic pressure regulator 5 and should intelligently put down permanent water tank 8, thus ensureing the hydraulic pressure of product water transfer pipeline 3 conveying all the time
For the value setting, realize automatically adjusting the hydraulic pressure in product water transfer pipeline 3 by using automatic pressure regulator 5, this device has
Structure is simple, response quickly and the stable advantage of pressure of supply water.
