A fixing block reserved hole 14 is penetrated on both the left and right sides of the front end of the tube bundle fixing block 13. A tube bundle fixing pin 15 is provided on the inner surface of the fixing block reserved hole 14, and a tube bundle adjusting piece 16 is provided on the outer surface of the rear end of the tube bundle fixing pin 15.

A water pumping pipe 19 is provided at the middle connection of the left end of the second sealing ring 8, and a water outlet pipe 20 is provided at the penetration of the lower right end of the steam trap body 1.
[0019] The working principle of the utility model is as follows: when the utility model is used, first, the first sealing ring 3 and the second sealing ring 8 are installed at the connection between the water suction pipe 19 and the steam trap body 1 to prevent water leakage. The sealing ring fixing hole 4 is used to fix the first sealing ring 3 and the second sealing ring 8. The sealing ring fixing hole 4 is located on the first sealing ring 3 and the second sealing ring 8. The sealing ring fixing pin 9 passes through the sealing ring fixing hole 4 to fix the first sealing ring 3 and the second sealing ring 8. The sealing ring adjusting member 10 can adjust the tightness of the first sealing ring 3 and the second sealing ring 8. The tight connection of the first sealing ring 3 and the second sealing ring 8 can effectively prevent water leakage. The front tube bundle 11 and the rear tube bundle 12 are the first sealing ring 3 and the second sealing ring The sealing joint of the ring 8 is fixed by the tube bundle fixing block 13 to fix the front tube bundle 11 and the rear tube bundle 12. During installation, the tube bundle fixing pin 15 passes through the reserved hole 14 of the fixing block to fix the front tube bundle 11 and the rear tube bundle 12 on the tube bundle fixing block 13 to keep the tube bundle stable, and the tube bundle adjusting piece 16 is used to adjust the position of the front tube bundle 11 and the rear tube bundle 12. By adjusting the tube bundle adjusting piece 16, the relative position of the front tube bundle 11 and the rear tube bundle 12 can be easily adjusted to adjust the tightness of the front tube bundle 11 and the rear tube bundle 12, thereby ensuring the sealing of the first sealing ring 3 and the second sealing ring 8; when the water pressure in the water pumping pipe 19 does not reach the set value, the steam trap body 1 is in a closed state. At this time, the piston is pressed against the valve seat under the action of the spring force to achieve a tight seal. To prevent water in the pipeline from flowing out, when the water pressure in the pipeline reaches the set value, the area of the pressure acting on the upper part of the piston is greater than the force applied by the spring under the piston, which causes the piston to start to rise, driving the piston rod 17 to move, thereby gradually opening the valve, and part of the water flows out. As the valve opens, more water flows out, further reducing the pressure inside the suction pipe 19. When the pipeline pressure drops below the set value, the spring begins to restore the force on the piston. Under the combined action of the spring force and the water pressure, the piston continues to rise, and the valve is fully opened to achieve maximum drainage. The water to be treated enters the suction pipe 19, and impurities such as sand, stones, leaves, etc. in the water to be treated will also enter the suction pipe 19. The filter screen 7 is installed in the filter screen frame 6, and the filter screen is The frame 6 is installed in the filter screen installation groove 5 slotted on the left side of the first sealing ring 3, and the filter screen 7 is installed between the first sealing ring 3 and the second sealing ring 8, and is located where the water flows, so as to intercept impurities such as sand, stones, leaves, etc. in the first time, thereby improving the filtering effect, and the filtered water source enters the water inlet pipe 2, and the water inlet pipe 2 discharges the filtered water flow into the interior of the steam trap body 1, and discharges the water flow through the water outlet pipe 20 installed at the penetration point on the lower side of the right end of the steam trap body 1; finally, when the water pressure in the pipeline drops to the minimum set value, the force of the spring on the piston is again greater than the force of the water pressure on the upper part of the piston, which causes the piston to begin to descend, driving the piston rod 17 to move, and gradually closing the valve. As the valve is closed, the pipeline pressure gradually returns to its initial state.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
