Description

Technical Field

[0001] The utility model relates to the technical field of steam traps, in particular to a free float type steam trap. Background Art

[0002] A steam trap is a valve, also known as a steam trap or a drain valve. It is installed in steam and condensate piping systems to block water and exhaust gas. It is mainly used to discharge condensate, air and carbon dioxide gas in the steam system as quickly as possible, while automatically preventing steam leakage to the maximum extent possible.

[0003] A Chinese patent discloses a new type of free float steam trap (authorization announcement number CN216520886U). When steam starts to enter in large quantities, part of the steam is discharged from the vent pipe, and under the action of its pressure, the piston is pushed to move and block the self-draining pipe. The spring is stretched, and the self-draining pipe is closed at this time, which does not affect the normal use of the valve body. After use, the spring drives the piston to reset.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing valve covers are connected by threads during installation. When the interior of the steam trap needs to be cleaned, inspected or repaired, the valve cover with threaded connection requires a lot of time and effort to disassemble and install, which not only reduces work efficiency, but may also damage the threads due to improper operation, further affecting the service life of the steam trap. Utility Model Content

[0010] Preferably, a thrust spring is fixed to the top of the pushing block, and the top of the thrust spring is connected to the bottom of the cover plate.

[0011] Preferably, the pushing block and the force-bearing block are both arc-shaped.

[0012] Preferably, sliding grooves are provided at both ends of the inner cavity of the slot, and sliding blocks are fixed at both ends of the force-bearing block.

DETAILED DESCRIPTION

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a free float type steam trap, comprising a valve body 1, a ring-shaped connecting block 2 is fixed on the surface of the valve body 1, a valve cover 3 is installed on the top of the ring-shaped connecting block 2, a thermosensitive element 4 is installed on the top of the valve cover 3, four notches 5 are opened on the top of the ring-shaped connecting block 2, four through grooves 6 are opened on the top of the valve cover 3, a cover plate 7 is fixed inside the through groove 6, and a movable groove 8 is opened on the top of the cover plate 7;

[0024] A fixing mechanism for fixing the position of the valve cover 3 is installed inside the through groove 6. When a fault occurs inside the valve body 1 or maintenance is required, the staff can use the valve cover 3 in conjunction with the fixing mechanism. In an emergency, if leakage or blockage occurs inside the valve body 1, the valve cover 3 can be quickly opened to quickly eliminate the fault, making it convenient for maintenance personnel to enter the interior for inspection, maintenance or replacement of parts, thereby avoiding the expansion of accidents, improving maintenance efficiency, reducing downtime, and ensuring the normal operation of the equipment.

[0025] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment: the fixing mechanism includes a movable rod 9 installed inside the movable groove 8, a pushing block 10 is fixed at the bottom of the movable rod 9, a force-bearing block 11 is installed inside the through-groove 6, one side of the force-bearing block 11 abuts against the other side of the pushing block 10, a connecting plate 12 is fixed on one side of the force-bearing block 11, a clamping block 13 is fixed on one side of the connecting plate 12, a return spring 17 is fixed on one side of the connecting plate 12, one side of the return spring 17 is connected to the inside of the notch 5, a clamping groove 14 is provided on one side of the inner cavity of the notch 5, a limiting hole 15 is provided on one side of the connecting plate 12, and a limiting rod 16 is fixed inside the through-groove 6. The staff moves the movable rod 9 upward to make the movable rod 9 drive the pushing block 10 to move, thereby releasing the limiting relationship of the pushing block 10 on one side of the force-bearing block 11, and then the return spring 17 will drive the connecting plate 12 and the clamping block 13 to disengage from the clamping groove 14 through its own force, so that the valve cover 3 can be quickly opened, thereby improving the maintenance efficiency, reducing the downtime, and ensuring the normal operation of the equipment.

[0026] Reference Figure 2 As shown, in this embodiment: the external shape of the block 13 matches the internal shape of the slot 14. When the external shape of the block 13 matches the internal shape of the slot 14, the stability and reliability of the block 13 and the slot 14 can be ensured, avoiding the loosening of the valve cover 3 due to misalignment or gap.

[0027] Reference Figure 2 As shown, in this embodiment: a thrust spring 18 is fixed to the top of the pushing block 10, and the top of the thrust spring 18 is connected to the bottom of the cover plate 7. By setting the thrust spring 18, when the staff pushes the block 10 to abut against the force block 11, the thrust spring 18 will generate a downward force to prevent the pushing block 10 from shaking due to external force.

[0028] Reference Figure 2 As shown, in this embodiment: the push block 10 and the force block 11 are both in the shape of an arc. The arc shape enables the push block 10 to provide smoother force transmission when contacting and pushing the force block 11. Compared with a straight line shape, the arc shape can distribute pressure more evenly and reduce local stress concentration, thereby improving the movement stability and smoothness of the entire system.

[0029] Reference Figure 4 As shown, in this embodiment: both ends of the inner cavity of the slot 5 are provided with slide grooves 21, and both ends of the force block 11 are fixed with sliders 22. Through the cooperation of the slide grooves 21 and the sliders 22, the force block 11 can maintain a stable path and direction when moving in the slot 5 without deviation, so that the pushing block 10 can be more accurately aligned with the force block 11.

[0030] Reference Figure 5As shown, in this embodiment: limiting grooves 19 are provided on both sides of the inner cavity of the movable groove 8, and limiting blocks 20 are fixed on both sides of the movable rod 9. The limiting blocks 20 slide in the limiting grooves 19, which can effectively prevent the movable rod 9 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of its movement.

[0031] Working principle: When a fault occurs inside the valve body 1 or maintenance is required, the staff will use the valve cover 3 in conjunction with the fixing mechanism. In an emergency, if leakage or blockage occurs inside the valve body 1, quickly opening the valve cover 3 can quickly eliminate the fault and facilitate maintenance personnel to enter the interior for inspection, maintenance or replacement of parts, thereby avoiding the expansion of accidents, improving maintenance efficiency, reducing downtime, and ensuring the normal operation of the equipment. The staff will move the movable rod 9 upwards so that the movable rod 9 drives the push block 10 to move, thereby releasing the restriction relationship between the push block 10 and the force-bearing block 11 on one side. Subsequently, the return spring 17 will use its own force to drive the connecting plate 12 and the block 13 to disengage from the slot 14, so that the valve cover 3 can be quickly opened, thereby improving maintenance efficiency, reducing downtime, and ensuring the normal operation of the equipment. When the external shape of the block 13 matches the internal shape of the slot 14, it can ensure that the block 13 and the slot 14 are in contact with each other. Stability and reliability, avoiding the loosening of the valve cover 3 due to misalignment or gap. By setting the thrust spring 18, when the staff pushes the block 10 to abut against the force block 11, the thrust spring 18 will generate a downward force to avoid the pushing block 10 from shaking due to external force. The arc shape enables the pushing block 10 to provide smoother force transmission when contacting and pushing the force block 11. Compared with the straight shape, the arc shape can distribute the pressure more evenly and reduce local stress concentration, thereby improving the movement stability and smoothness of the entire system. Through the cooperation of the slide groove 21 and the slider 22, the force block 11 can maintain a stable path and direction when moving in the slot 5, and there will be no deviation, so that the pushing block 10 can be more accurately aligned with the force block 11. The limit block 20 slides in the limit groove 19, which can effectively prevent the movable rod 9 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of its movement.
