Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a single-flow high-pressure stop valve. Background Art

[0002] The stop valve is one of the most widely used valves. It is popular because the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is suitable not only for medium and low pressures, but also for high pressures.

[0003] Nowadays, a single-flow high-pressure stop valve is often provided with a filter plate inside when in use to prevent external impurities from entering the single-flow high-pressure stop valve along with the medium. However, as the use time increases, impurities on the filter plate will accumulate, which will easily clog the filter plate. At this time, the filter plate needs to be cleaned. However, the existing single-flow high-pressure stop valve often needs to remove the filter plate for cleaning, which makes the cleaning process more complicated and easily affects the normal use of the single-flow high-pressure stop valve. Therefore, in order to solve the above defects, the inventors propose a single-flow high-pressure stop valve. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The utility model discloses a single-flow high-pressure stop valve. Figure 1-5 As shown, it includes a one-way stop valve body 1, an annular tube 2 is fixedly installed at the water inlet of the one-way stop valve body 1, and two filter boxes 3 are fixedly installed on the left and right sides of the outer surface of the annular tube 2. The two filter boxes 3 are both connected to the annular tube 2. When the external medium enters the annular tube 2, it will enter the filter box 3.

[0022] Furthermore, two filter plates 4 are provided inside the two filter boxes 3 to filter the medium entering the filter boxes 3 .

[0023] There are lifting slots 301 on both sides of the left and right sides of the filter box 3. Two guide rods 302 are fixedly installed inside the two lifting slots 301, and two brush plates 303 are slidably connected to the outer surfaces of the four guide rods 302. The brush plates 303 can be lifted and lowered along the guide rods 302.

[0024] Two springs 304 are fixedly installed on the inner bottom surfaces of the two lifting grooves 301, and the four guide rods 302 are respectively passed through the inside of the four springs 304. The two brush plates 303 are respectively fixedly connected to the four springs 304. When the brush plates 303 descend, they will squeeze the springs 304.

[0025] The top surfaces of the two brush plates 303 are fixedly mounted with pressing rods 305, and the two pressing rods 305 are extended to the outside of the filter box 3. By applying pressure to the pressing rods 305, the brush plates 303 can be lowered and the springs 304 can be squeezed. When no pressure is applied to the pressing rods 305, the squeezed springs 304 will push the brush plates 303 to reset, thereby allowing the brush plates 303 to clean the filter plates 4. The ends of the two pressing rods 305 extending to the outside of the filter box 3 are fixedly mounted with rubber heads.

[0026] The left and right sides of the filter box 3 are rotatably connected with the rotating shaft 401, and the two filter plates 4 are sleeved on the outer surfaces of the two rotating shafts 401. When the rotating shaft 401 rotates, it will drive the filter plates 4 to rotate.

[0027] The two rotating shafts 401 extend to one end of the outside of the filter box 3 and are fixedly installed with gears 402. One side of the outer top surface of the filter box 3 is rotatably connected to the first threaded rod 403, and the other side of the outer top surface of the filter box 3 is fixedly installed with a first sliding rod 405. The outer surface of the first threaded rod 403 is threadedly connected to a rack 404, and the rack 404 is slidably connected to the first sliding rod 405. The rack 404 is meshed with the two gears 402. Rotating the first threaded rod 403 can make the rack 404 move. When the rack 404 moves, it can drive the two gears 402 to rotate, and then drive the rotating shaft 401 and the filter plate 4 to rotate, so that the filter plate 4 can be rotated to a horizontal state or a longitudinal state. When the filter plate 4 is in the longitudinal state, it will contact the brush plate 303, and then the lifting of the brush plate 303 can clean the filter plate 4.

[0028] Discharge ports 306 are fixedly mounted on both sides of the outer bottom surface of the filter box 3 , and the cleaned impurities can be discharged through the discharge ports 306 .

[0029] When the bottle 308 is in the bottle, the bottle 308 is in the bottle and the filter bag 306 is turned to the bottle. When the bottle 308 is in the bottle, the filter bag 306 is turned to the bottle. When the bottle 308 is in the bottle, the filter bag 306 is turned to the bottle. When the bottle 308 is turned, the filter bag 306 is turned to the bottle. When the bottle 308 is turned, the filter bag 306 is turned to the bottle. When the bottle 308 is turned, the filter bag 306 is turned to the bottle.

[0030] A baffle 3012 is slidably connected between the two filter boxes 3, and both ends of the baffle 3012 extend to the interior of the two filter boxes 3 respectively. The baffle 3012 can move between the two filter boxes 3. When the baffle 3012 moves to the left, it can block the medium from entering the filter box 3 on the left. When the baffle 3012 moves to the right, it can block the medium from entering the filter box 3 on the right. This makes it convenient to clean the filter plate 4 of one of the filter boxes 3 while allowing the filter plate 4 in the other filter box 3 to perform filtering operations, so as to avoid affecting the normal flow of the medium when cleaning the filter plate 4.

[0031] A fixing rod 3011 is fixedly connected between the outer surfaces of the two filter boxes 3, and a limiting hole 3015 is opened on one side of the fixing rod 3011. A connecting block 3014 is fixedly installed on one side of the baffle 3012, and the connecting block 3014 is slidingly connected to the limiting hole 3015. A third threaded rod 3013 is rotatably connected to one side of the fixing rod 3011, and the connecting block 3014 passes through the limiting hole 3015 and is threadedly connected to the third threaded rod 3013. When the third threaded rod 3013 rotates, the connecting block 3014 can move along the limiting hole 3015. When the connecting block 3014 moves, it will drive the baffle 3012 to move.

[0032] The working principle of the present invention is as follows: when the filter plate 4 in the left filter box 3 needs to be cleaned, the third threaded rod 3013 is rotated to make the connecting block 3014 drive the baffle 3012 to move to the left to block the medium from entering the left filter box 3. At this time, the medium will enter the right filter box 3, and the filter box 3 on the right can perform the filtering operation normally. The first threaded rod 403 is rotated to make the rack 404 move along the first sliding rod 405. The moving rack 404 drives the two gears 402 to rotate, so that the two filter plates 4 in the left filter box 3 rotate to the longitudinal state to contact the two brush plates 303 respectively, and then pressure is applied to the pressing rod 305 to cooperate with the spring 304 to make the brush plates 303 rise and fall to clean the filter plates 4, and then the second threaded rod 307 is rotated to pull the sealing plug 310 out of the discharge port 306, so that the cleaned impurities can be discharged through the discharge port 306. The right filter box 3 is the same as above.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
