Description
Technical Field
The utility model relates to a water purification machine spare part technical field, concretely relates to purification water second grade reverse osmosis movable seal sampling joint.
Background
The reverse osmosis technology of purified water is based on the pressure effect of osmotic pressure and completes the filtration process through the capillary action of a membrane. The water purifying machine membrane component connection mode: through multi-stage connection (generally, one stage and two sections), the first stage is that raw material water is subjected to membrane separation through primary pressurization, and the first stage and the second stage are subjected to membrane separation again through secondary pressurization. The membrane permeate is also called fresh water, i.e. water filtered out by the reverse osmosis membrane under pressure. Otherwise, the water which does not pass through the membrane is concentrated water.
The reverse osmosis membrane adopted by the water purifying equipment is a semi-permeable membrane which only allows water molecules to pass through but does not allow solute to pass through. The reverse osmosis technology utilizes the selective adsorption of a membrane and a screening mechanism for organic matters in addition to the principles of reverse osmosis and reverse osmosis. The reverse osmosis membrane has a pore diameter of 10X 10-10m or less in many cases, and the separation target is an organic substance having an ionic range and a molecular weight of about several hundred in a solution.
The existing connector assembly is only used for connecting a reverse osmosis membrane with a cover plate, and then an O-shaped sealing ring is used for effectively separating concentrated water and fresh water outside the reverse osmosis membrane. However, the existing connector assembly is gradually blocked by the reverse osmosis membrane in the long-term use process, and acts under the high pressure of the concentrated water, the reverse osmosis membrane can deform, the connector and the cover plate are separated more easily at the tail end of the connector assembly of the sampling port, and then the concentrated water enters the fresh water filtered by the reverse osmosis membrane, so that the water quality is poor. Therefore, the reverse osmosis membrane needs to be cleaned frequently, and then has to be replaced. The use cost of the reverse osmosis membrane is increased.

Drawings
FIG. 1 is a schematic sectional view of the present invention;
FIG. 2 is a schematic top view of the retainer ring;
FIG. 3 is a schematic structural view of a movable valve body;
in the figure: 1. the sampling joint comprises a sampling joint body, 2, a connector, 3, a sealing ring assembly groove, 4, a movable valve body, 4a, a valve core, 4b, a guide rod, 5, a limiting ring, 6, a sealing gasket, 7 and a fresh water pipe.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically connected or connected by pipelines; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the utility model relates to a purification water second grade reverse osmosis movable seal connects for taking a sample, including the joint for taking a sample body 1, sealing washer assembly groove 3 has been seted up in the outside of the connector 2 of joint for taking a sample body 1, the sealing washer is equipped with to sealing washer assembly groove 3 endotheca.
A T-shaped movable valve body 4 is placed in the connector 2, the movable valve body 4 comprises a top disc-shaped valve core 4a and a bottom long rod-shaped guide rod 4b, the outer diameter of the valve core 4a is larger than the inner diameter of a fresh water pipe 7 in the sampling connector body 1, and the diameter of the guide rod 4b is smaller than the inner diameter of the fresh water pipe 7.
The reason for the above design is that the inventor finds that the existing water purification equipment can operate well all the time at the initial stage of the reverse osmosis membrane. Along with the decline of the permeability of reverse osmosis membrane of the extension of time, its pressure progressively increases, and its reverse osmosis membrane can appear micro deformation gradually, and deformation about 0.5 millimeter can appear in every filter core, if several filter cores become the serial link, for example 5 to 6 filter cores are established ties, will appear the clearance about 3 millimeters, and this long clearance often adds to hold on the connector. At this time, the concentrated water which is not filtered by the reverse osmosis membrane passes through the sealing ring through the gap, and the concentrated water enters the fresh water which is filtered by the reverse osmosis membrane. At the sampling joint, the concentrated water can also permeate into the backflow water and enter the fresh water, so that the quality of the produced water is reduced, and the produced water cannot reach the qualified standard.
Therefore, the utility model discloses improve the structure of sampling joint, add movable valve body 4 in it. This kind of unique design, when dense water is not palirrhea, fresh water can be to movable valve body 4 production pressure, makes movable valve body 4 enter into connector 2 in, and fresh water can be smoothly followed connector 2 and flowed out this moment, can carry out the sample operation. And when dense water oozes in, because palirrhea dense water give that movable valve body 4 reverse pressure can be greater than the pressure of fresh water to movable valve body 4, movable valve body 4 can be pushed to fresh water pipe 7 department, sealed fresh water pipe 7, avoids dense water to get into.
In order to guarantee under the convenient prerequisite of assembly, can effectively carry on spacingly to movable valve body 4, prevent that it from deviating from connector 2. The utility model discloses still provide modified technical scheme, in modified technical scheme, the inside fixed mounting in top of connector 2 has the spacing ring 5 that prevents that movable valve body 4 from deviating from connector 2, the apopore has been seted up on spacing ring 5.
Preferably, the limiting ring 5 is in threaded connection with the connecting head 2.
In order to effectively improve the sealing performance of the valve element 4 a. The utility model also provides a modified technical scheme, in modified technical scheme, the fixed sealed pad 6 that is provided with in case 4a bottom of movable valve body 4.
Preferably, the sealing gasket 6 has a trapezoidal structure.
For smooth and easy of direction, the utility model discloses a diameter of guide bar 4b is preferred to be less than 1.5 ~ 2mm than fresh water pipe 7's internal diameter.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
