DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A corrosion-resistant water heating valve provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings. Embodiment 1:

[0024] Combination Figure 1-Figure 12As shown, a corrosion-resistant water heating valve provided by the present invention includes a valve body mechanism 100, an opening and closing mechanism 200 arranged in the valve body mechanism 100, and a liquid flow guide mechanism 300 arranged in the valve body mechanism 100. The valve body mechanism 100 is used to provide a low-corrosion transfer channel for the solution, the opening and closing mechanism 200 is used to control the flow of the solution in the inner cavity of the two groups of water delivery components 190, and provide effective lifting kinetic energy for the liquid flow guide mechanism 300; the liquid flow guide mechanism 300 is used to transfer the solution in an orderly manner and reduce the corrosion of the inner wall of the valve body caused by solution accumulation.

[0025] The valve body mechanism 100 includes a transfer chamber 110, a sealing bottom cover 140 disposed at the bottom of the transfer chamber 110, a sealing top cover 160 disposed at the top of the transfer chamber 110, and two sets of water delivery components 190 disposed on the transfer chamber 110; The water delivery assembly 190 includes an end pipe 191, a drainage groove 192 is provided inside the end pipe 191, a liquid blocking pad 193 and an anti-seepage sleeve 194 provided in the middle of the liquid blocking pad 193 are provided in the hole at the inner end of the end pipe 191, and a liquid accumulation groove is provided at the inner end of the end pipe 191 and the inner end plate of the liquid blocking pad 193, and the liquid accumulation groove is communicated with the drainage groove 192; The opening and closing mechanism 200 includes a threaded neck rod 210 disposed in the threaded sleeve 170, two cushion blocks 220 are installed at the top of the threaded neck rod 210, and a rotating wheel 230 is installed at the top of the two cushion blocks 220; The threaded section of the threaded neck 210 is adapted to penetrate into the inner cavity of the transfer bin 110; A vertical hole is formed inside the threaded neck 210, and two fixing bolts 240 are disposed inside the threaded neck 210; A pull rod distance adjustment assembly 270 is disposed inside the threaded neck rod 210, and the pull rod distance adjustment assembly 270 is used to control the lifting height of the traction pull rod 260; A cylindrical hole adapted to the clamp seat 250 is opened in the middle of the sealing top cover 160, and both ends of the clamp seat 250 are adapted to penetrate into the interior of the limiting groove 180; The liquid flow guiding mechanism 300 includes two sets of flow control components 380, two auxiliary partitions 370 and two main partitions 360, a plug pad 340 arranged in the inner cavity of the transfer bin 110 and a drain pipe 350 arranged at the bottom of the plug pad 340, and the port of the drain pipe 350 is connected to the liquid accumulation tank.

[0026] Existing water heating valves use a unified channel. This drainage channel will cause certain wear on the inner wall of the valve body during the repeated opening and closing process. As the wear gradually increases, the worn parts will be affected by factors such as solution and scale, and the corrosion will be accelerated. In severe cases, the sealing performance of the valve body will be reduced, and the pressure of the solution will be affected.

[0027] When the device is in use, the external water inlet pipe and the drainage pipe need to be connected to the two end pipes 191 respectively; When the solution needs to be transferred, the rotating wheel 230 can be controlled to rotate counterclockwise, and the threaded neck rod 210 as a whole will slowly rise with the clamp seat 250. At the same time, the threaded neck rod 210 and the traction rod 260 will carry the plug pad 340 and the drainage pipe 350 to lift upward until the plug pad 340 is aligned with the end plates on the inner sides of the two blocking pads 193. At this time, the ports at both ends of the drainage pipe 350 can be connected with the two liquid accumulation grooves, and the two groups of flow control components 380 that are linked and pulled will also move closer to the two blocking pads 193 until the groove 384 is connected with the drainage groove 192. At this time, the cavity in the passage can transfer the solution normally. When it is necessary to close the valve body and the passage of the solution, the wheel 230 is controlled to rotate clockwise according to the above steps until the plug pad 340 and the drain pipe 350 are reset under the push of the linkage component. At this time, the two sets of flow control components 380 can re-block the inner cavities of the other two end tubes 191. At this time, the solution in the inner cavities of the two end tubes 191 can be driven out, and the drain pipe 350 will move to the pre-loading tank 120. At this time, the solution in the drain pipe 350 can be released from the pre-loading tank 120 and released from the drain hole inside the sealing bottom cover 140. At this time, the maintenance and subsequent inspection of the valve body will not interfere with the external water inlet pipe and drain pipe, while improving the service life of the valve body. Embodiment 2:

[0028] Combination Figure 3 and Fig.10 As shown, based on Example 1, the valve body mechanism 100 also includes a second sealing ring 150 arranged in the inner ring groove of the sealing bottom cover 140, a screw sleeve 170 is arranged in the hole on the top of the sealing top cover 160, and a screw hole is opened inside the screw sleeve 170.

[0029] Preferably, the drainage hole inside the sealed bottom cover 140 needs to be set according to the sealing performance between the plug pad 340 and the inner cavity of the transfer bin 110. When the solution inside the drain pipe 350 does not need to be discharged, the sealed bottom cover 140 does not need to have a drainage hole.

[0030] A trapezoidal limiting groove 180 is provided inside the sealing top cover 160; A first sealing ring 130 is disposed in the port outside the transfer bin 110; A pre-loading tank 120 is provided at the bottom of the inner cavity of the transfer bin 110, and the drain pipe 350 is adapted to penetrate into the inner cavity of the pre-loading tank 120; A drainage hole is formed inside the sealing bottom cover 140 .

[0031] Preferably, after the end plates on the inner sides of the two liquid blocking pads 193 are aligned with the plug pad 340, the upper cavity formed by the plug pad 340 and the transfer bin 110 can be kept in a clean state. At this time, the linkage components located in the clean sealed cavity can be prevented from being corroded. At the same time, the partitioned cavity can form a dry-wet separation, thereby effectively improving the service life of each component inside the valve body. Embodiment 3:

[0032] Combination Figure 8-Figure 12 As shown, based on the embodiment 1, the pull rod distance adjustment assembly 270 includes two first guide rods 271 and two fourth guide rods 276, a gusset plate 272 movably mounted on the first guide rods 271, and a third guide rod 274 is arranged in the slot at the top of the gusset plate 272; The third guide rod 274 and the fourth guide rod 276 are respectively provided with a bottom clamp 275 and a top clamp 277; A reinforcing tension spring 278 is connected to the bottom clamp 275 and the top clamp 277 .

[0033] Preferably, in the initial state, the bottom end of the traction rod 260 and its truss 310 will be located at the bottom of the inner cavity of the transfer bin 110. At this time, the two buckle plates 272 will be elastically pulled by the two reinforcing springs 278 and flipped upward. At this time, the closed plug pad 340 and the drain pipe 350 can be stably pressed at the bottom of the inner cavity of the transfer bin 110 and limited by the pre-installed groove 120.

[0034] There are two pinch plates 272, and a second guide rod 273 is disposed inside the two pinch plates 272; The clasp plate 272 is made of a stainless steel pipe material, and a through hole is opened at the outer end of the clasp plate 272. The fixing bolt 240 is adapted to pass through the through hole to fix the clasp plate 272 after the rollover.

[0035] Preferably, the first guide rod 271 is made of a plastic metal rod. When the outer end of the buckle plate 272 is pressed and overturned, the first guide rod 271 that bears the pressure in the middle of the buckle plate 272 will bend within a certain range, so that the ends of the two buckle plates 272 constrained by the second guide rod 273 can be stably lifted upward, and with the fixation of the two fixing bolts 240, the two buckle plates 272 can remain stable after overturning, so that the extension state of the main partition 360 and the auxiliary partition 370 can be adjusted to improve the regulation of the lateral displacement spacing of the two plugs 382. Embodiment 4:

[0036] Combination Figure 4 , Fig.11 and Fig.12As shown, in the above embodiment, the flow control assembly 380 includes a plug 382 movably installed in the inner cavity of the end tube 191, two third sealing rings 383 are arranged in two annular grooves outside the plug 382, ​​and an end rod 381 is installed in the middle of the inner end of the plug 382; A groove 384 is formed at the bottom of the plug 382 , and the groove 384 and the drainage groove 192 are adapted to each other.

[0037] Preferably, two third sealing rings 383 are used to adapt to the inner cavity of the end tube 191. When the end rod 381 is subjected to traction and drives the plug 382 to move horizontally stably, the two third sealing rings 383 can prevent the solution from overflowing and effectively expel the solution remaining in the inner cavity of the end tube 191, thereby ensuring the cleanliness of the end tube 191 after transferring the solution to reduce the speed at which its inner wall is corroded.

[0038] A truss 310 is installed on two adjacent secondary partitions 370 and the main partition 360, and a shaft sleeve 320 is installed in the middle of the truss 310; Two vertical holes are opened inside the truss 310, and two symmetrically distributed positioning screws 330 are arranged in the two vertical holes; The threaded sections of the two positioning screws 330 are installed in the two studs at the top of the plug gasket 340.

[0039] Preferably, an anti-seepage gasket is provided on the side of the plug pad 340, and the drain pipe 350 can be fixed to the middle part of the bottom surface of the plug pad 340 by means of bolts, and rubber gaskets are provided on the ports at both ends of the drain pipe 350. As the plug pad 340 is steadily lifted along the inner cavity of the transfer bin 110, the two ends of the drain pipe 350 can be adapted to connect with the ports of the two liquid accumulation tanks, thereby avoiding overflow due to excessive pressure during solution transfer.

[0040] Working principle and use process of the present invention: In home decoration, construction engineering or industrial piping systems, valves are indispensable key components, and water heating valves are the most important switches in home heating systems. They are used in heating, water supply and drainage systems of homes or commercial buildings; However, there are certain defects in the current water heating valves. Since the valve core and the valve body share the same cavity, during long-term water supply and drainage operations, scale or other impurities in the warm water will corrode the inner wall of the cavity. In severe cases, it will cause the subsequent discharged water to become turbid or cause the valve body's sealing performance to decrease. As the valve body's sealing performance decreases, the pressure of the water heating valve's supply will weaken. The device sets the traditional structure that shares the same cavity into a hierarchical structure. When the water inlet pipe and the drainage pipe are respectively connected to the flanges at the outer ends of the two end pipes 191, when the valve body is in a closed state, the two plugs 382 will block the inner cavities of the two end pipes 191. At this time, the stagnant water in the inner cavities of the two end pipes 191 will be driven out, and part of the temporarily stored solution will be stored in the drain pipe 350. As the drain pipe 350 enters the pre-installed tank 120, the stored solution can be released from the inside of the drain pipe 350, and finally released from the drainage hole inside the sealing bottom cover 140. Finally, after the drain pipe 350 descends to the inner cavity of the pre-installed tank 120, the solution in the inner cavity of the drain pipe 350 can be isolated and stored. At this time, the cavity in the inner cavity of the valve body can be prevented from being soaked in the solution and causing rust. When the solution needs to be discharged, the wheel 230 can be controlled to rotate counterclockwise, and the threaded neck 210 will be lifted upward along the inside of the screw sleeve 170, and the clamp seat 250 movably installed at the bottom of the threaded neck 210 will pull the two main partitions 360 and the two auxiliary partitions 370 to lift upward. At this time, the two sets of flow control components 380 movably installed on the two auxiliary partitions 370 will be compressed and contracted toward the inside of the end pipe 191 until the groove 384 moves to Directly above the drainage groove 192, the end tube 191, the groove 384 and the drainage groove 192 will form a channel for infusion. At the same time, the plug pad 340, which is pulled up synchronously, will move between the inner end plates of the two blocking pads 193. At this time, the inner end plates of the two blocking pads 193 are aligned with the plug pad 340, and the drainage pipe 350 installed at the bottom of the plug pad 340 will dock with the two drainage grooves 192. At this time, the valve body will form an effective diversion channel; After the drain pipe 350 is docked with the two drainage grooves 192, the two buckle plates 272 can be flipped downward, and the two buckle plates 272 after flipping can be fixed by two fixing bolts 240. At this time, the spacing of the two flow control components 380 along the inner cavity of the two end pipes 191 can be further adjusted. At this time, the main partition plate 360 ​​and the auxiliary partition plate 370 can be compressed and tightened to be parallel by the truss 310. At this time, the parallel main partition plate 360 ​​and the auxiliary partition plate 370 will be retracted into the inner part of the limit groove 180, thereby effectively ensuring the safe and effective transfer of the solution along the channel; When not in use, the drain pipe 350 can be separated from the two drainage grooves 192 according to the above steps, and the two sets of flow control components 380 can be reset to the inside of the two end pipes 191. At this time, the inner cavity of the device can avoid rust caused by being immersed in the solution for a long time. After a certain period of use, the sealing bottom cover 140 can be removed and the drain pipe 350 can be replaced, thereby effectively increasing the service life of the valve body without interfering with the water inlet pipe and the drain pipe, so as to improve the convenience of using the valve body.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
