A filter cartridge 1 32 and a filter cartridge 2 33 are arranged on one side of the filter box 9. The end of the filter cartridge 2 33 away from the filter cartridge 1 32 is fixedly connected to the connecting sleeve 34, and the inner groove cross-section of the connecting sleeve 34 is a T-structure. The end of the filter cartridge 2 33 close to the filter cartridge 1 32 is fixedly connected to the connecting plate 35 matching the connecting sleeve 34. The inner part of the connecting plate 35 is slidably connected to the limit block 31 with an L-shaped structure. The limit block 31 and the connecting plate 35 are connected. A spring 310 is fixedly connected between the limit block 31 and the push rod 311 is fixedly connected to the side of the limit block 31 away from the spring 310, and a guide groove 312 with an arc-shaped structure is provided on the side of the filter box 9 close to the push rod 311; when the steam thermal power disc steam trap is in use, the condensate and air are transported to the inside of the valve body 1 through the limit block 31, and then enter the inside of the filter box 9 through the connecting hole, and the impurities in the condensate are filtered through the filter cartridge 2 33, and then the condensate enters the inside of the air chamber 7 through the steam trap hole 10, and pushes the valve plate 8 to move upward, and is discharged through the outlet pipe 5, and the air passes through the steam trap hole 10. When entering the air chamber 7, the valve plate 8 will block the drain hole 10 to discharge the condensed water in the steam pipe. When it is necessary to clean or replace the filter cartridge 2 33, the filter cartridge 2 33 is turned over 90 degrees to drive the push rod 311 to slide along the arc surface of the inner wall of the guide groove 312. The push rod 311 will be driven by the elastic force of the spring 310 to drive the limit block 31 to be stuck in the connecting sleeve 34, so that the connecting plate 35 on the filter cartridge 2 33 is connected with the connecting sleeve 34 of the filter cartridge 1 32, and then the filter cartridge 2 33 is pulled out of the filter box 9.

After the filter cartridge 33 is moved to the outside of the filter box 9, the filter cartridge 33 can be moved or the push rod 311 can be pressed to separate the filter cartridge 33 and the filter cartridge 1 32, so that the filter cartridge 33 can be cleaned or replaced. At the same time, a spare filter cartridge is put into the other side of the filter box 9, which is convenient for subsequent cleaning and replacement of the filter cartridge 1 32, thereby improving the flexibility of the device. When the filter cartridge 33 is disassembled, the slider 36 slides out of the slide groove 1 37, and the slide groove 1 37 opens downward, thereby preventing impurities in the slide groove 1 37 from entering the drain hole 10;

[0033] The sliding block 36 is fixedly connected to the side of the connecting plate 35 near the push rod 311, and the push rod 311 passes through one side of the sliding block 36 and extends to the outside of the sliding block 36. A sliding groove 2 38 is provided on the side of the filter box 9 near the sliding block 36, and a sliding groove 1 37 is provided on the side of the filter box 9 away from the sliding block 36. The sliding groove 1 37 and the sliding groove 2 38 are connected through the guide groove 312, and the width of the sliding groove 2 38 is slightly smaller than the sliding groove 1 37. When installing the filter cartridge 1 32, the sliding block 36 and the sliding groove 2 38 are aligned, and then the push rod 311 is pressed to push the sliding block 36 into the sliding groove 2 38, and the filter cartridge 1 32 is pushed to move into the filter box 9. The sliding groove 2 38 can limit the filter cartridge 1 32. When the filter cartridge 2 33 is disassembled, the sliding block 36 moves along the guide groove 312, so that the sliding block 36 moves to the side of the sliding groove 1 37, thereby improving the stability of the movement of the filter cartridge 2 33.

[0034] A T-shaped fixing block 39 is symmetrically fixedly connected to the surface of the connecting sleeve 34, and the fixing block 39 facilitates flipping of the filter cartridge 1 32 or the filter cartridge 2 33;

[0035] The surfaces of the connecting sleeve 34 and the connecting plate 35 are fixedly connected with sealing rings to improve the sealing effect of the filter box 9;

[0036] Embodiment 2:

[0037] In order to facilitate the positioning of the filter cartridge 1 32 and the filter cartridge 2 33 after installation, the above technical solution is provided with a mounting assembly 4 inside the filter box 9 in this embodiment. The mounting assembly 4 includes a screw 41, a moving block 42 and a limiting plate 43. The filter box 9 is rotatably connected with the screw 41, and the moving block 42 is screwed on the surface of the screw 41, and the moving block 42 is slidably connected to the inside of the filter box 9. The two ends of the filter box 9 are fixedly connected to the side of the connecting sleeve 34 and the connecting plate 35 with a limiting plate 43 of a trapezoidal structure, and the surface of the connecting sleeve 34 and the connecting plate 35 is provided with a limiting groove on the side of the limiting plate 43; the bottom end of the screw 41 passes through the filter box 9 The movable block 42 is driven upward by rotating the screw rod 41, and then the movable block 42 drives the limiting plates 43 on both sides to move upward, and the two sets of limiting plates 43 are respectively inserted into the limiting grooves inside the connecting sleeve 34 and the limiting grooves of the connecting plate 35, thereby limiting the positions of the filter cartridge 2 33 and the filter cartridge 1 32, and improving the stability of the filter cartridge installation. When the filter cartridge 2 33 is disassembled, the two sets of limiting plates 43 can be driven downward by reversing the screw rod 41, and the limiting of the filter cartridge 2 33 is released, so that the filter cartridge 2 33 can be disassembled, thereby improving the flexibility of the device.

[0038] Working principle: When the steam thermal power disc-type steam trap is in use, the condensate and air are transported to the inside of the valve body 1 through the limit block 31, and then enter the inside of the filter box 9 through the connecting hole, and the impurities in the condensate are filtered through the filter cartridge 2 33, and then the condensate enters the air chamber 7 through the drain hole 10, and pushes the valve plate 8 to move upward and is discharged through the outlet pipe 5. When the air enters the air chamber 7 through the drain hole 10, the valve plate 8 will block the drain hole 10 to realize the discharge of condensate in the steam pipe. When it is necessary to clean or replace the filter cartridge 2 33, the two sets of limit plates 43 can be driven downward by reversing the screw 41 to release the limit on the filter cartridge 2 33, and the filter cartridge 2 33 is driven to flip ninety degrees through the two sets of fixing blocks 39, so that the push rod 311 is driven to slide along the arc surface of the inner wall of the guide groove 312, and the push rod 311 will be driven by the elastic force of the spring 310 The limit block 31 is inserted into the connecting sleeve 34, so that the connecting plate 35 on the second filter cartridge 33 is connected with the connecting sleeve 34 of the first filter cartridge 32, and then the second filter cartridge 33 is pulled out of the filter box 9. At the same time, the limit block 31 will pull the filter cartridge 1 32 to move to the original filter cartridge 2 33 position, so that the filter cleaning and replacement will not affect the normal operation of the valve body 1. After the filter cartridge 2 33 moves to the outside of the filter box 9, the filter cartridge 2 33 can be moved or the push rod 311 can be pressed to separate the filter cartridge 2 33 and the filter cartridge 1 32, so that the filter cartridge 2 33 can be cleaned or replaced. At the same time, a spare filter cartridge is placed through the other side of the filter box 9, which is convenient for subsequent cleaning and replacement of the filter cartridge 1 32, thereby improving the flexibility of the device. When the filter cartridge 2 33 is disassembled, the slider 36 slides out of the slide slot 1 37, and the slide slot 1 37 opens downward, thereby preventing impurities in the slide slot 1 37 from entering the drain hole 10;

[0039] When installing the filter cartridge 1 32, the slider 36 is aligned with the slide groove 2 38, and then the push rod 311 is pressed to push the slider 36 into the slide groove 2 38, and the filter cartridge 1 32 is pushed to move into the filter box 9, and then the moving block 42 is driven to move upward by rotating the screw 41, and then the moving block 42 will drive the limiting plates 43 on both sides to move upward, and the two sets of limiting plates 43 will be respectively stuck in the limiting grooves inside the connecting sleeve 34 and the limiting grooves of the connecting disk 35, thereby limiting the positions of the filter cartridge 2 33 and the filter cartridge 1 32, thereby improving the stability of the filter cartridge installation.
