Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a gate valve repair and flushing device. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of movement of the gate is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed, and cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Usually, metal materials are welded onto the sealing surface to increase wear resistance. Nowadays, gate valves are also used to transport mineral slurries.

[0003] The gate valve consists of a handwheel, screw, sealing device, gate, upper chamber of valve body, and lower chamber of valve body. When the gate valve is closed, slurry flows from the gate gap to the upper chamber of valve body, water flows out from the sealing device, and ore sand remains in the upper chamber of valve body and hardens. When the gate valve needs to be opened, the gate is jammed by the hardened ore sand in the upper chamber of valve body, and the gate valve is rendered unusable and must be replaced with a new one. Therefore, to solve the above defects, the inventor proposes a gate valve repair and flushing device. Utility Model Content

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] This utility model discloses a gate valve repair and flushing device, such as Figure 1-5 As shown, the device includes a valve body 1, a connecting pipe 2 that runs through both sides of the valve body 1, a water tank 3, and a booster pump 5. A fixed pipe 501 is fixedly connected between the water tank 3 and the inlet of the booster pump 5. A transmission pipe 502 is fixedly installed at the outlet of the booster pump 5, and a tee 503 is fixedly installed between the transmission pipe 502 and one end of the booster pump 5. Both ends of the tee 503 are fixedly installed with delivery hoses 504. The booster pump 5 transmits water from the water tank 3 to the two delivery hoses 504 through the fixed pipe 501, the transmission pipe 502, and the tee 503.

[0023] Connecting cylinders 4 are fixedly installed on both sides of the outer surface of the connecting pipe 2, and the two connecting cylinders 4 are connected to both sides of the connecting pipe 2.

[0024] Two connecting rods 507 are slidably connected to one side of the outer surface of the connecting cylinder 4. Parts of the two connecting rods 507 are located inside the connecting cylinder 4, and the other parts of the two connecting rods 507 are located outside the connecting cylinder 4. A movable plate 505 is fixedly installed at the outer end of the two connecting rods 507, and a fixed plate 508 is fixedly installed at the inner end of the two connecting rods 507.

[0025] When the two connecting rods 507 move, they will drive the movable plate 505 and the fixed plate 508 to move. The fixed plate 508 has a nozzle 5082 on the side away from the connecting rods 507. When the fixed plate 508 moves, it will drive the nozzle 5082 to move so that the nozzle 5082 can move inside the connecting pipe 2, so that water can be used to wash and repair the mineral sand evenly.

[0026] Two springs 506 are fixedly installed on one side of the movable plate 505 and the connecting rod 507. Both springs 506 are fixedly connected to the outer surface of the connecting cylinder 4, and the two connecting rods 507 pass through the inside of the two springs 506 respectively. When the movable plate 505 moves to one side of the connecting cylinder 4, the movable plate 505 will squeeze the two springs 506.

[0027] The delivery hose 504 extends through the movable plate 505 into the interior of the connecting cylinder 4. The movable plate 505 is fitted on the outer surface of the delivery hose 504, and one end of the delivery hose 504 extending into the interior of the connecting cylinder 4 passes through the fixed plate 508 and is fixedly connected to the nozzle 5082. The delivery hose 504 can transmit water to the nozzle 5082.

[0028] A movable frame 5081 is fixedly installed on one side of the nozzle 5082 on the fixed plate 508. The movable frame 5081 has two rotating shafts 5083 rotatably connected to both sides inside. Both rotating shafts 5083 are fixedly connected to the nozzle 5082. The nozzle 5082 can rotate at a certain angle through the two rotating shafts 5083 so that the angle of the nozzle 5082 can be adjusted when spraying.

[0029] Both sides of the movable frame 5081 are fixedly installed with torsion springs 5084, and two rotating shafts 5083 pass through the inside of the two torsion springs 5084 respectively. Both torsion springs 5084 are fixedly connected to the nozzle 5082.

[0030] A steel wire 509 is slidably connected to one side of the movable plate 505. Part of the steel wire 509 is located outside the connecting cylinder 4, and the other part of the steel wire 509 is located inside the connecting cylinder 4. The end of the steel wire 509 inside the connecting cylinder 4 passes through the fixing plate 508 and is fixedly connected to the nozzle 5082. When the user pulls the steel wire 509 outward from the connecting cylinder 4, it will cause the nozzle 5082 to rotate at a certain angle to one side of the connecting cylinder 4. When the steel wire 509 is released, the torsion spring 5084 will reset the nozzle 5082 so that the angle of the nozzle 5082 can be adjusted.

[0031] A rotating rod 202 is rotatably connected to one side of the inside of the water tank 3, and multiple stirring rods 203 are fixedly installed on the outer surface of the rotating rod 202. A micro motor 201 is fixedly installed on one side of the outer surface of the water tank 3, and the output end of the micro motor 201 is fixedly connected to the rotating rod 202. The user can inject water and cleaning solution into the water tank 3 in a certain proportion according to actual needs. The micro motor 201 drives the rotating rod 202 to rotate, so that the stirring rods 203 stir and mix the water and cleaning solution. A drain pipe 204 is fixedly installed at the bottom of one side of the outer surface of the water tank 3, and the drain pipe 204 can drain the remaining liquid in the water tank 3.

[0032] A water inlet pipe 2011 is fixedly installed on the top surface of the water tank 3. Water or cleaning fluid can be injected into the water tank 3 through the water inlet pipe 2011. The inside of the water inlet pipe 2011 is equipped with a filter plate 2012, which can filter out large particles of impurities in the water to effectively prevent pipe blockage.

[0033] Four support plates 2015 are fixedly installed on the inner wall of the water inlet pipe 2011, and the top surface of each of the four support plates 2015 is rotatably connected to a limiting block 2016. The top surface of the filter plate 2012 has four limiting holes 2013. The limiting block 2016 is passed through the limiting hole 2013, and then the limiting block 2016 is rotated so that it does not coincide with the limiting hole 2013, thus completing the installation of the filter plate 2012. The outer surface of the water inlet pipe 2011 is threaded with a sealing cap 2014, which can prevent the liquid in the water tank 3 from leaking out of the water inlet pipe 2011.

[0034] The working principle of this utility model is as follows: First, water and cleaning solution are injected into the water tank 3 through the water inlet pipe 2011. The micro motor 201 drives the rotating rod 202 to rotate, and the stirring rod 203 stirs and mixes the water and cleaning solution. The pressurized water pump 5 transmits the water in the water tank 3 to two delivery hoses 504 through the fixed pipe 501, the transmission pipe 502, and the tee 503. The water is then transmitted to the nozzle 5082 through the two delivery hoses 504 and sprayed onto the gate plate through the nozzle 5082. On both sides, the user repeatedly pushes the movable plate 505 to repeatedly compress the spring 506 during rinsing. When the movable plate 505 moves, the connecting rod 507 pushes the fixed plate 508 to move, thereby moving the nozzle 5082 inside the connecting pipe 2. By repeatedly pulling the steel wire 509 outward from the connecting cylinder 4, the nozzle 5082 can be rotated at a certain angle to adjust the angle of the nozzle 5082 so as to rinse the mineral sand evenly.
