Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1, 2 and 3, a special stop valve with a multiple filtering device comprises a valve seat 1. The middle part of the valve seat 1 is provided with a stop seat 2. The middle part of the stop seat 2 is connected with a valve rod 3 through a bearing, the tail end of the valve rod 3 is connected with a hand wheel 4, and the periphery of the valve rod 3 is connected with a mounting seat 5 through threads. The hand wheel 4 drives the valve rod 3 to rotate, and the valve rod 3 gradually moves along the thread when rotating, so that the stop seat 2 connected with the valve rod 3 through a bearing moves up and down. When the stop seat 2 moves downwards to abut against the bottom of the valve seat 1, the stop valve is closed, and when the stop seat 2 moves upwards to separate from the bottom of the valve seat 1, the stop valve is opened.

The valve seat 1 has an inlet pipe 6 on one side of the stop seat 2 and an outlet pipe 7 on the other side. The stop seat 2 is hinged with a moving rod 8 at one side of the inflow pipe 6. The tail end of the moving rod 8 is hinged with a driving rod 9. One end of the driving rod 9 is provided with a connecting component 10. The drive rod 9 is connected with a filter cartridge 11 through a connecting assembly 10.

Through the arrangement of the filter cartridge 11, the fluid with particles and viscous substances entering the inflow pipe 6 is firstly subjected to the filtering sedimentation treatment of the filter cartridge 11 and then passes through the stop valve.

As shown in fig. 4, 5 and 6, a first filter screen 12 is fixedly connected between the filter cartridge 11 and the driving rod 9 through a bolt. The connecting assembly 10 comprises two mounting blocks 101 arranged in the middle of the first filter screen 12, and a clamping rod 102 is fixedly connected between the mounting blocks 101. The driving rod 9 is provided with a catching groove 103 corresponding to the catching rod 102. The clamping rod 102 is clamped and connected with the clamping groove 103. Under the action of a large external force, the clamping rod 102 and the clamping groove 103 can be separated from each other. When the fluid passes through the first filter screen 12, particulate matters in the fluid can be filtered on one side of the first filter screen 12, and impurities are prevented from entering the stop valve.

And L-shaped fixing blocks 13 are arranged on two sides of the middle part of the filter cartridge 11. A second filter screen 14 is clamped on the two fixing blocks 13 together. The second filter screen 14 is provided with a fixing groove 18 corresponding to the fixing block 13. Filter screen two 14 joints are in the middle part of cartridge filter 11, and when outside fluid entered into cartridge filter 11, in proper order entered into the stop valve after the filtration of filter screen two 14 and filter screen one 12, under the double filtration, particulate impurity was mostly clear away.

The end of the filter cartridge 11 is provided with a hinge seat 15. A filter screen III 16 is hinged on the hinge seat 15. As shown in fig. 7 and 8, a torsion spring 17 is disposed between the third filter screen 16 and the hinge base 15. As shown in the figure, in the initial state, when the torsion spring 17 is in the compressed state, an angle of 45 degrees is formed between the third filter screen 16 and the hinge seat 15. When the flow velocity of fluid is fast, exert great impact force to the surface of filter screen three 16 for filter screen three 16 rotates to cartridge filter 11, and according to the difference of the flow velocity of fluid, the rotation angle also is different, and the biggest bottom that can make filter screen three 16 and cartridge filter 11 butt.

Wherein, a settling agent (not shown) is put into a space formed between the first filter screen 12 and the second filter screen 14 and the filter cylinder 11. The settling agent settles after reacting with the viscous substance.

Wherein, cartridge filter 11 can fix outward and set up the sealing washer as sealed use, reduces the flow in the gap between fluid process cartridge filter 11 and the inflow pipe 6, and this stop valve can't realize thoroughly sealing, probably can exist fluidic leakage, but is little to whole influence, the stop valve described in this application realized its technical purpose that can filter the fluidic of granule impurity and viscidity impurity to can guarantee that the stop valve has longer life.

The whole work flow and effect are as follows:

1. when the filter cartridge 11 is installed, the clamping rod 102 on the first filter screen 12 is clamped and connected with the corresponding clamping groove 103. Then, the hand wheel 4 is rotated, so that the stop seat 2 is driven to move upwards when the valve rod 3 is rotated. The upward movement of the block 2 causes the inward movement of the driving rods 9. The driving rod 9 moves to drive the filter cartridge 11 to move. The filter cartridge 11 enters the inflow tube 6;

2. when the first filter screen 12 is impacted by viscous substances and particles, the first filter screen 12 rotates, so that the first filter screen 12 is abutted to the filter cylinder 11, and fluid enters the filter cylinder 11 after being filtered by the first filter screen 12;

3. after being filtered by the second filter screen 14, the mixture enters a space between the second filter screen 14 and the third filter screen 16;

4. a settling agent between the second filter screen 14 and the third filter screen 16 reacts with the fluid to settle the viscous substance;

5. and the filtered water enters a stop valve after being filtered by a filter screen III 16. When the stop valve is in the closed state and the fluid flow rate is low, the first filter screen 12 is in the initial state shown in the figure, most of the fluid does not pass through the first filter screen 12 for filtration, and only the second filter screen 14 and the third filter screen 16 are needed for filtration, so that the filtration pressure of the first filter screen 12 is reduced, because the first filter screen 12 is in contact with the fluid in the first step, the number of particles filtered by the first filter screen 12 is large, and the first filter screen 12 is prone to failure when the first filter screen 12 is used for filtration all the time, so that the pressure of the first filter screen 12 is shared by the second filter screen 14 and the third filter screen 16.

6. After a period of time, the subside agent in the cartridge filter 11 consumes greatly and filter screen one 12, when filter screen two 14 and filter screen three 16 surface adhesion are more impurity, the clearance cartridge filter 11 needs to be changed, the valve rod 3 is rotated, make and cut off seat 2 and 1 bottom butt of disk seat, at this moment, cartridge filter 11 exposes, outwards use great power pulling cartridge filter 11, make joint piece and joint groove 103 on the filter screen one 12 break away from, thereby dismantle cartridge filter 11, then dismantle the cleaning back with filter screen one 12, filter screen two 14, install again on the actuating lever 9 after carrying out the preliminary cleaning to filter screen three 16, can continue to use the stop valve. Normally, the shut-off valve is connected to the other lines and in the closed state, the filter cartridge 11 is located outside the inflow pipe 6 and in the other lines.
