When the fixed rod 204a needs to be removed, manually move the movable baffle 304f downward to make it rotate and open, and the fixed rod 204a can be removed from the installation groove. The inside of the groove 302 is taken out, thereby achieving the purpose of higher disassembly efficiency.

When in use, when the float 204b is installed, it is installed inside the installation groove 302, and the movable baffle 304f is pressed down by the fixed rod 204a, so that the two movable baffles 304f are rotated and opened, and then pass The movable baffle 304f drives the movable block 304b to move upwards, and the U-shaped slide plate 304h is driven to slide inwardly by the movable block 304b. At this time, the installation groove 302 is fully opened, and the fixed rod 204a can be placed inside it, and the inside of the installation groove 302 has A certain space is used to facilitate the fixed rod 204a to move up and down inside it. Wherein, the top of the movable baffle 304f is inclined. When the fixed rod 204a pushes down the movable baffle 304f, it can be more conveniently promoted to rotate. The chute 304b-a and the second chute 304b-b are oppositely arranged so that when the movable baffle 304f rotates, the first shaft 304f-a can drive the movable block 304b while sliding in the first chute 304b-a Move upward, and at the same time, the second shaft 304h-a drives the U-shaped slide plate 304h to move outward during the sliding process in the second chute 304b-b; At the same time, the counterweight 304d-a drives the movable block 304b to move downward, thereby driving the movable baffle 304f and the U-shaped slide 304h to reset, and at the same time, the sealing strip 304d-b acts as a seal to avoid condensation during use Entering the bottom of the counterweight 304d-a, the counterweight 304d-a and the movable block 304b are moved upward by buoyancy, which affects the stability of the installation. In the initial state, the emptying valve 102b is opened, and the excess air in the housing 101 It is discharged from the outlet pipe 104b through the second emptying groove 102c and the first emptying groove 104c. When the condensed water enters the inside of the valve through the water inlet pipe 103b, the condensed water is blocked and protected by the fixed frame 103c and the deflector 103d. The diversion makes the condensed water flow into the bottom of the floating ball 204b directly from both sides. Compared with the prior art that flows directly from the middle of the valve body, the valve can quickly release the condensed water to the inside of the housing 101. The ball part 204 is jacked up. At this time, the setting of the buffer plate 305 is used to limit the position of the fixed rod 204a, so as to avoid a large deviation in the process of its moving up and down, and cause certain damage to the valve disc 202 and the valve seat 201. Then the fixed rod 204a is further limited by the stoppers 204a-a to prevent it from rotating during installation and use, which will affect the use, and the force-bearing area at the bottom of the floating ball 204b is improved through the setting of the diversion slope 204c, which is extremely Greatly improves the water outlet efficiency, and at the same time filters the condensed water through the filter 103e to prevent large particles of impurities from entering the interior of the housing 101, causing damage to internal parts, and then when the condensed water enters the interior of the valve seat 201, the condensed water itself The flow drives the impeller 203b and the connecting rod 203a to rotate, so that the condensed water is discharged in a vortex shape. At this time, the flow rate of the condensed water can be increased through the impeller 203b, which greatly improves its drainage efficiency. When steam enters the shell 101, it is emptied The valve 102b is closed by heat to avoid steam leakage, and then the steam is introduced to the top of the floating ball 204b through the deflector 103d. At this time, the pressure of the steam on the floating ball 204b is increased through the setting of the inclined plate 204d, and then the gravity of the floating ball 204b itself It can move down more quickly and conveniently, close the valve seat 201, and at the same time play the role of water seal through the condensed water remaining inside the housing 101, so that the sealing effect of the valve is better, which greatly avoids the Steam leakage, when installing the steam trap, move the steam trap to the designated position, and then connect the steam trap to the pipeline in the pipeline through the first connecting piece 401 and the second connecting piece 403, so that the support The bottom of 404 is located on the ground or a support, wherein the first pipe 401c is connected to the water inlet pipe in the pipeline, and the first pipe 401c is connected to the water inlet pipe through the cooperation between the first flange 401a and the second flange 401b. The connection between 103b is more convenient and stable. The second pipe 403c is connected to the water outlet pipe in the pipeline. Through the cooperation between the third flange 403a and the fourth flange 403b, the connection between the second pipe 403c and the water outlet pipe 104b The connection between them is more convenient and stable, and then the fixed plate 404f is installed at the designated position by means of screws, etc., and then the trap is supported by the telescopic rod 404b and the fixed pipe 404c to prevent it from being directly suspended in the air, and the first pipe 401c is added and the load of the second pipe 403c, resulting in the risk of rupture, and then the sliding block 404d is used to limit the telescopic rod 404b to prevent it from detaching from the inside of the fixed pipe 404c, and at the same time, the buffer spring 404e is applied to the trap to push upward. Force, so that it has a certain buffer space, avoiding hard fracture at the connection during use, which brings great inconvenience to use, and then the staff can lift the trap more conveniently through the handle 402c, improving handling and The movement efficiency is improved, and then the protective effect of the top of the trap is improved through the rubber block 402d, so as to prevent foreign matter from directly hitting the top of the trap and causing damage to it.
