Description

Technical Field

[0001] This utility model is a bellows stop valve with filtering function, belonging to the technical field of stop valve equipment. Background Technology

[0002] Gate valves, also known as stop valves, are a type of forced sealing valve. Their sealing is achieved by applying torque to the valve stem, which in turn applies pressure to the valve disc in the axial direction, causing the valve disc sealing surface to fit tightly against the valve seat sealing surface, thus preventing the medium from leaking along the gap between the sealing surfaces.

[0003] Most existing shut-off valves have a certain filtering effect on liquids, but they generally lack the function of cleaning the filter element, and manual cleaning is inconvenient. There is an urgent need for a bellows shut-off valve with filtering function to solve the above-mentioned problems. Utility Model Content

This utility model has a reasonable structure and good practicality. It not only facilitates the cleaning and unblocking of the filter pores of the filter element, but also allows for the collection and convenient discharge of the cleaned impurities, thus improving the convenience of the device during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bellows stop valve with filtering function, comprising a bellows stop valve body and a side mounting plate. A rectangular shell is connected to the input end of the bellows stop valve body. A guide groove is provided in the upper center of the rectangular shell. A rectangular frame is fixedly connected inside the rectangular shell. A filter plate is installed on the left side of the rectangular frame by bolts. A through groove is provided below the rectangular shell. A sealing plate is inserted into the through groove and connected to the rectangular shell by bolts. A drive motor is installed on the upper right side of the side mounting plate. The rotating shaft of the drive motor passes through the side mounting plate. A lead screw is fixedly connected to the left end of the rotating shaft of the drive motor. A rectangular block with a threaded hole is threadedly connected to the outside of the lead screw. A square tube receiving groove is provided on the left side of the rectangular block with the threaded hole. A square tube is slidably installed inside the square tube receiving groove. A square shell is fixedly connected below the square tube.

[0006] Furthermore, an electric push rod is installed inside the upper part of the square shell, and an L-shaped plate is installed at the lower end of the telescopic shaft of the electric push rod. A spiked unblocking plate is fixed to the right side of the horizontal end of the L-shaped plate.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a bellows stop valve with filtering function, including a bellows stop valve body 1 and a side mounting plate 3. A rectangular shell 2 is connected to the input end of the bellows stop valve body 1. A guide groove 7 is provided in the middle of the upper part of the rectangular shell 2. A rectangular frame 22 is fixed inside the rectangular shell 2. A filter plate 14 is installed on the left side of the rectangular frame 22 by bolts. A through groove 21 is provided at the bottom of the rectangular shell 2. A sealing plate 20 is inserted into the through groove 21. The sealing plate 20 is connected to the rectangular shell 2 by bolts. The side mounting plate 3 is located on the right side. A drive motor 4 is installed on the upper side. The rotating shaft of the drive motor 4 passes through the side mounting plate 3. A lead screw 5 is fixed to the left end of the rotating shaft of the drive motor 4. A rectangular block 9 with a threaded hole is threadedly connected to the outside of the lead screw 5. A square tube receiving groove 18 is provided on the left side of the rectangular block 9 with a threaded hole. A square tube 10 is slidably installed inside the square tube receiving groove 18. A square shell 11 is fixed below the square tube 10. This design solves the problem that most shut-off valves have a certain filtering effect on liquids, but generally lack the function of cleaning the filter element, and manual cleaning is inconvenient.

[0020] As the first embodiment of this utility model: an electric push rod 19 is installed on the upper part of the square shell 11. An L-shaped plate 12 is installed at the lower end of the telescopic shaft of the electric push rod 19. A spiked unblocking plate 13 is fixedly connected to the right side of the horizontal end of the L-shaped plate 12. Through the connection and cooperation between the electric push rod 19 and the L-shaped plate 12, the height of the L-shaped plate 12 can be adjusted, thereby adjusting the position of the spiked unblocking plate 13. By setting the spiked unblocking plate 13, it is convenient to insert and unblock the filter holes of the filter plate 14. A guide strip 8 is fixedly connected to the lower right end of the rectangular block 9 with threaded holes. The lower end of the guide strip 8 is slidably installed in the guide groove 7. By sliding the lower end of the guide strip 8 in the guide groove 7, it is convenient to provide guidance for the rectangular block 9 with threaded holes, thereby improving the stability of the rectangular block 9 with threaded holes when moving. A side mounting plate 3 is installed on the upper right end of the rectangular shell 2. The spiked unblocking plate 13 has protrusions 17 on the middle of its front and rear sides respectively. A sealing frame 6 is installed on the left side of the rectangular shell 2. The sealing frame 6 has first limiting grooves 15 on the middle of its front and rear sides respectively. The rectangular shell 2 has second limiting grooves 16 on the middle of its front and rear sides respectively. By having protrusions 17 on the middle of its front and rear sides respectively, the spiked unblocking plate 13 can cooperate with the two first limiting grooves 15 and the two second limiting grooves 16 to maintain the stability of the spiked unblocking plate 13 when it moves.

[0021] As a second embodiment of this utility model: When unblocking work is required, first start the drive motor 4. The rotating shaft of the drive motor 4 drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the rectangular shell 2 and the guide strip 8 to move to the left along the guide groove 7. When the rectangular shell 11 moves to the appropriate position, pull the square tube 10 to adjust the lateral position of the spiked unblocking plate 13. Then start the electric push rod 19 to drive the L-shaped plate 12 down, so that the spiked unblocking plate 13 is located on the left side of the sealing frame 6. Then push the square tube 10 to partially retract the square tube 10 into the square tube receiving groove 18, so that... The two protrusions 17 pass through the two first limiting grooves 15 and enter the two second limiting grooves 16. Then, the drive motor 4 drives the lead screw 5 to reverse, causing the rectangular block 9 with threaded holes to move to the right. This causes the spiked unblocking plate 13 to move stably, and the multiple spikes of the spiked unblocking plate 13 to insert into the multiple filter holes of the filter plate 14. Then, the drive motor 4 drives the lead screw 5 to perform reciprocating forward and reverse motion, thereby repeatedly inserting and unblocking the multiple filter holes of the filter plate 14. The impurities that fall off during unblocking will fall on the sealing plate 20, and the staff can remove the sealing plate 20 for cleaning.
