[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a quick-install flange connection combination valve, including a valve body 1, a valve body 2 on one side of the valve body 1, a filter screen 3 that engages between the valve body 1 and the valve body 2, the filter screen 3 being able to filter impurities; a flange 4 fixedly mounted on the surface of the valve body 1, a flange 5 fixedly mounted on the surface of the valve body 2, four evenly spaced support blocks 6 fixedly mounted on one side of the flange 4, the support blocks 6 penetrating the flange 2 and extending beyond it, inclined blocks 7 slidingly mounted on the surface of the support blocks 6, a box 8 fixedly mounted at the top of the valve body 2, and a lead screw 9 rotatably mounted inside the box 8, the rotation of the lead screw 9 driving two sliding plates on its surface. 10 moves synchronously in opposite directions, combined with bracket 11, thereby driving the two corresponding inclined blocks 7 to adjust in opposite directions. Through the movement of inclined blocks 7, combined with the design of support block 6, flange 1 4 and flange 2 5 are tightly fitted, thereby enabling valve body 1 and valve body 2 2 to be quickly assembled. During the assembly of the valve, it is not necessary to use tools to tighten the bolts one by one, reducing operation steps and improving assembly efficiency. Both ends of the screw 9 are connected to the slide plate 10 by screw nut thread, and the bottom of the slide plate 10 is fixedly provided with bracket 11. The bracket 11 is fixedly connected to the inclined block 7. The surface of the screw 9 is provided with adjustment component 12, which facilitates the screw 9 to be rotated in the forward and reverse directions.

[0026] The adjusting assembly 12 includes a worm gear 1201, which is fixedly installed in the middle of the lead screw 9. A worm 1202 is meshed with one side of the worm gear 1201. The top end of the worm 1202 passes through the housing 8 and is fixedly equipped with a handwheel 1203. The bottom end of the worm 1202 is rotatably connected to the bottom end of the inner wall of the housing 8. Through the adjusting assembly 12, the handwheel 1203 drives the worm 1202 to rotate, which, combined with the meshing worm gear 1201, drives the lead screw 9 to rotate and adjust, making operation more convenient. At the same time, the worm gear 1201 and worm 1202 transmission has a self-locking function. When the handwheel 1203 is stopped, the lead screw 9 can be stably maintained in the current position.

[0027] The threads at both ends of the lead screw 9 turn in opposite directions, and the bottom end of the slide plate 10 is slidably connected to the top of the inner wall of the box 8. Two guide rods 13 are symmetrically slidably provided on the top of the slide plate 10, and one end of the guide rod 13 is fixedly connected to the inner wall of one side of the box 8. The threads at both ends of the lead screw 9 turn in opposite directions, so that the two slide plates 10 can move synchronously in opposite directions when the lead screw 9 rotates. The guide rods 13 are provided so that the slide plates 10 play a limiting and guiding role during the movement.

[0028] The surface of the support block 6 is provided with a groove 14, the inclined block 7 is slidably connected to the groove 14, and the size of the groove 14 is larger than the size of the inclined block 7; the groove 14 provided in the support block 6 allows the inclined block 7 to move without any restriction.

[0029] A sealing strip is fixedly provided at the connection between valve body 1 and valve body 2, and a sealing strip is fixedly provided at the connection between filter screen 3 of valve body 1 and valve body 2. The sealing strips 1 and 2 are respectively provided at the connection between valve body 1 and valve body 2 and filter screen 3 and valve body 2, which can play a sealing role.

[0030] A connecting pipe 15 is fixedly provided in the middle of valve body 1 and valve body 2, and a threaded sleeve 16 is sleeved on one end of the connecting pipe 15. The surface of the threaded sleeve 16 is provided with an anti-slip groove. By using the connecting pipe 15 in the middle of valve body 1 and valve body 2, combined with the threaded sleeve 16, it is easy to connect to the external pipeline by thread, thereby enabling the valve to be installed quickly.

[0031] When using this valve device, firstly, the filter screen 3 is engaged inside the valve body 2. This filter screen 3 can effectively intercept impurities in the fluid, thus playing a filtering role. Then, using the flange 4 on the valve body 1, the support block 6 is inserted into the flange 5 to complete the initial connection. Next, the operator turns the handwheel 1203. The rotation of the handwheel 1203 drives the worm gear 1202 to rotate synchronously. Since the worm gear 1202 and the worm wheel 1201 are meshed, the rotation of the worm gear 1202 is converted into the rotation adjustment of the worm wheel 1201. The rotation of the worm wheel 1201 further drives the lead screw 9 to rotate. Since the threads at both ends of the lead screw 9 turn in opposite directions, under the guidance of the guide rod 13, the rotation of the lead screw 9 will drive the two slide plates 10. The sliding plate 10 moves synchronously in opposite directions along the guide rod 13. The movement of the sliding plate 10 drives the two connected brackets 11 to adjust synchronously in opposite directions, thereby causing the two corresponding inclined blocks 7 to move synchronously in opposite directions as well. During the movement, the inclined blocks 7 slide along the inclined groove 14, causing flange 1 4 and flange 2 5 to fit tightly together, thereby realizing the rapid assembly of valve body 1 and valve body 2. Compared with the traditional valve assembly method, there is no need to use tools to tighten the bolts one by one, which simplifies the operation steps and improves the assembly efficiency. In addition, the transmission mechanism composed of worm gear 1201 and worm 1202 has a self-locking function. When the operator stops turning the handwheel 1203, the screw 9 can be stably held in the current position, ensuring that the assembly state of valve body 1 and valve body 2 is stable and reliable.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
