Description

Technical Field

[0001] This utility model relates to the field of drain valves, specifically a multi-functional drain valve. Background Technology

[0002] A gas storage tank is a sealed container used to store gas. During its operation, the gas may contain moisture or water vapor may enter from the environment, causing a certain amount of water to gradually accumulate inside the tank. If this water remains for a long time, it may affect the normal working efficiency of the gas storage tank and even cause problems such as corrosion of internal components. Therefore, gas storage tanks usually have a drainage function, and the water inside needs to be discharged regularly or as needed through a specific device to ensure the stable operation of the gas storage tank.

[0003] In existing technology, to drain water from the gas storage tank, a solenoid valve is usually installed at the drain outlet of the gas storage tank. As an electromagnetically controlled industrial device, the solenoid valve is a basic component of automation used to control fluids. It changes its on / off state by receiving control signals. When drainage is required, the control device sends an energizing signal to the solenoid valve. The coil of the solenoid valve is energized and generates magnetic force, which drives the valve core to move, opening the drain outlet and draining the water from the gas storage tank. When drainage is complete or drainage is no longer required, the control device cuts off the power to the solenoid valve. The valve core returns to its original position under the action of springs and other reset elements, closing the drain outlet and stopping drainage.

[0004] However, due to the limitations of the solenoid valve's structure and operating characteristics, its energizing time is relatively short. Under normal circumstances, the single energizing time of the solenoid valve is usually only a few seconds. This means that in the actual drainage process, the water inside the air tank cannot be continuously discharged through the solenoid valve for a long time. In addition, the solenoid valve can only be controlled by electricity. Once a malfunction occurs, personnel cannot manually drain the water. The solenoid valve must be repaired or replaced before normal drainage can be restored. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multifunctional drain valve to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional drain valve, including an electric push rod, one end of which is provided with a push rod, the end of which is connected to a connecting rod, one end of which is provided with a sealing gasket, a metal rod installed inside the sealing gasket, a pull ring fixed to the bottom of the metal rod, a mounting block provided at the bottom of the electric push rod, a connecting sleeve connected to the bottom of the mounting block, water outlet holes on both sides of the outer wall of the connecting sleeve, a connecting base connected to the bottom of the connecting sleeve, and a drain hole inside the connecting base.

[0007] By adopting the above technical solution, the problem of low efficiency in draining water from the gas storage tank using a solenoid valve is solved. The drain outlet of the gas storage tank is sealed by a gasket. When it is necessary to drain the water accumulated inside the gas storage tank, the electric push rod is activated. The electric push rod drives the connecting rod to move into the gas storage tank through the push rod at the end, thereby releasing the seal of the drain hole by the gasket at the end of the connecting rod. The electric push rod is gear driven, so the electric push rod can maintain a certain state for a long time, thereby allowing the water inside the gas storage tank to be continuously drained.

[0008] The present invention is further configured such that a conical surface and a flat surface are respectively provided on both sides of the sealing gasket, the drain hole is conical, and the diameter of the drain hole is smaller than the diameter of the flat surface of the sealing gasket.

[0009] Preferably, the conical and flat surfaces of the sealing gasket can effectively close the drain hole at the bottom of the connecting base when they mate with the connecting base, while also ensuring that the high-pressure gas in the gas storage cylinder does not leak out when the electric push rod is not in the open state.

[0010] The present invention is further configured such that a second connecting end is provided at the top of the connecting rod, a first connecting end is installed at the end of the push rod, and the first connecting end and the second connecting end are connected by a thread.

[0011] Preferably, the connecting rod is connected and fixed to the push rod by a threaded connection between the first connecting end and the second connecting end.

[0012] The present invention is further configured such that a mounting block is fixed at the bottom of the electric push rod, a second internal thread is provided on the top inner wall of the connecting sleeve, and the mounting block and the connecting sleeve are connected by threads.

[0013] Preferably, the electric actuator is connected to the mounting block and the second internal thread at the top of the connecting sleeve, thereby enabling the electric actuator to be assembled with the connecting sleeve.

[0014] The present invention is further configured such that the bottom end of the connecting sleeve is provided with an external thread, the top of the connecting base is provided with a first internal thread, the outer wall of the connecting base is connected with an air storage cylinder, the outer wall of the air storage cylinder is provided with a drain outlet, and the connecting base is threadedly connected to the drain outlet.

[0015] Preferably, the connecting sleeve is threadedly connected to the first internal thread on the top of the connecting base via the external thread at the bottom, thereby allowing the connecting sleeve and the connecting base to be assembled together, and the assembled device is fixedly installed onto the gas storage cylinder via the connecting base.

[0016] The present invention is further configured such that a power supply hole is provided inside the connecting base, and the inside of the power supply hole is filled with sealant, and a power cord is connected to the outer wall of the electric push rod.

[0017] Preferably, the power cord of the electric actuator extends to the outside of the gas storage cylinder through the power hole inside the connecting base, and the inside of the power hole is filled with sealant. The sealant is injected into the connection gap between the power cord and the power hole. The cured sealant can seal the power hole and prevent the gas inside the gas storage cylinder from leaking out of the power hole.

[0018] The present invention is further provided that a heating coil is provided inside the connecting sleeve, and the heating coil is capable of constant temperature heating.

[0019] Preferably, the heating coil can heat the water near the water outlet during cold seasons to prevent the water inside the gas storage tank from freezing.

[0020] The present invention is further configured such that the connecting rod and the rubber pad are made of rubber, and the metal rod is fixedly installed inside the sealing gasket by a vulcanization process.

[0021] Preferably, the metal rod can bend the rubber pad, which has good elastic deformation ability, to produce deformation.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the problem of low efficiency in draining water from the gas storage tank using a solenoid valve by incorporating an electric push rod, a connecting base, a connecting sleeve, a connecting rod, and a sealing gasket. The drain outlet of the gas storage tank is sealed by the sealing gasket. When it is necessary to drain the water accumulated inside the gas storage tank, the electric push rod is activated. The electric push rod drives the connecting rod to move into the gas storage tank through the push rod at its end, thereby releasing the sealing gasket at the end of the connecting rod from the drain hole. The electric push rod is gear-driven, so it can maintain a certain state for a long time, allowing the water inside the gas storage tank to be continuously drained.

[0024] This utility model, by setting up a connecting rod, a sealing gasket, a metal rod, and a pull ring, allows personnel to tilt and pull the pull ring upwards when the electric push rod malfunctions and cannot operate. This causes the sealing gasket connected to the end of the metal rod to bend at a certain angle, creating a gap between the sealing gasket and the inner wall of the connecting base. The air pressure inside the air storage cylinder forces water through the gap into the drain hole, allowing the water inside the air storage cylinder to flow out. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Please see Figure 1 — Figure 7The device includes an electric push rod 1, with a push rod 103 at one end and a connecting rod 4 at the end of the push rod 103. A sealing gasket 401 is located at one end of the connecting rod 4, and a metal rod 6 is installed inside the sealing gasket 401. A pull ring 601 is fixed to the bottom of the metal rod 6. A mounting block 102 is located at the bottom of the electric push rod 1, and a connecting sleeve 3 is connected to the bottom of the mounting block 102. Water outlet holes 301 are opened on both sides of the outer wall of the connecting sleeve 3. A connecting base 2 is connected to the bottom of the connecting sleeve 3, and a drain hole 202 is opened inside the connecting base 2. An air storage cylinder 5 is fitted around the electric push rod 1, and the air storage cylinder... The outer wall of the cylinder 5 is provided with a drain port 501, which solves the problem of low efficiency in draining water inside the gas storage cylinder using a solenoid valve. The drain port 501 of the gas storage cylinder 5 is sealed by a sealing gasket 401. When it is necessary to drain the water accumulated inside the gas storage cylinder 5, the electric push rod 1 is activated. The electric push rod 1 drives the connecting rod 4 to move into the gas storage cylinder 5 through the push rod 103 at the end, thereby releasing the sealing gasket 401 at the end of the connecting rod 4 from the drain hole 202. The electric push rod 1 is gear driven, so the electric push rod 1 can maintain a certain state for a long time, thereby allowing the water inside the gas storage cylinder 5 to be continuously drained.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 and Figure 7 The sealing gasket 401 has a conical surface and a flat surface on both sides, and the drain hole 202 is conical. The diameter of the drain hole 202 is smaller than the diameter of the flat surface of the sealing gasket 401. When the conical surface and flat surface of the sealing gasket 401 are engaged with the connecting base 2, the drain hole 202 at the bottom of the connecting base 2 can be effectively closed. At the same time, it ensures that the high-pressure gas in the gas storage cylinder 5 will not leak out when the electric push rod 1 is not open.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 7 The top of the connecting rod 4 is provided with a second connecting end 402, and the end of the push rod 103 is provided with a first connecting end 104. The first connecting end 104 and the second connecting end 402 are connected by threads. The connecting rod 4 is connected and fixed to the push rod 103 by the threaded connection of the first connecting end 104 and the second connecting end 402.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The electric push rod 1 has a mounting block 102 fixed at its bottom. The inner wall of the top of the connecting sleeve 3 is provided with a second internal thread 302. The mounting block 102 and the connecting sleeve 3 are connected by threads. The electric push rod 1 is connected to the mounting block 102 and the second internal thread 302 at the top of the connecting sleeve 3, so that the electric push rod 1 and the connecting sleeve 3 can be assembled.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 and Figure 6 The bottom end of the connecting sleeve 3 is provided with an external thread 303, and the top of the connecting base 2 is provided with a first internal thread 203. The outer wall of the connecting base 2 is connected to the air storage cylinder 5, and the outer wall of the air storage cylinder 5 is provided with a drain outlet 501. The connecting base 2 is threadedly connected to the drain outlet 501. The connecting sleeve 3 is threadedly connected to the first internal thread 203 at the top of the connecting base 2 through the external thread 303 at the bottom, so that the connecting sleeve 3 and the connecting base 2 are assembled together, and the assembled device is fixedly installed on the air storage cylinder 5 through the connecting base 2.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 6 The connecting base 2 has a power hole 201 inside, and the inside of the power hole 201 is filled with sealant. The outer wall of the electric push rod 1 is connected to a power cord 101. The power cord 101 of the electric push rod 1 extends to the outside of the gas storage cylinder 5 through the power hole 201 inside the connecting base 2. The inside of the power hole 201 is filled with sealant. The sealant is injected into the connection gap between the power cord and the power hole 201. The cured sealant can seal the power hole 201 and prevent the gas inside the gas storage cylinder 5 from leaking from the power hole 201.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The connecting sleeve 3 is equipped with a heating coil 7, which can heat at a constant temperature. The heating coil 7 can heat the water near the water outlet 301 in the cold season to prevent the water inside the gas storage cylinder 5 from freezing.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 The connecting rod 4 and the rubber pad 401 are made of rubber. The metal rod 6 is fixed inside the sealing pad 401 through a vulcanization process. The metal rod 6 can bend the rubber pad 401, which has good elastic deformation ability, to produce deformation.

[0044] In practical operation, before installing the device onto the drain outlet 501 on the outer wall of the gas storage cylinder 5, the device is first assembled. First, the connecting sleeve 3 is connected to the mounting block 102 at the bottom of the electric push rod 1 via the second internal thread 302 at its top. Then, the connecting rod 4 is fixed by connecting the second connecting end 402 at its end to the first connecting end 104 at the end of the push rod 103 via a threaded connection, so that the connecting rod 4 is installed and connected to the end of the push rod 103. Then, the connecting base 2 is installed and connected to the bottom of the connecting sleeve 3 via the first internal thread 203 of the connecting base 2 and the external thread 303 of the connecting sleeve 3, thereby completing the overall assembly operation of the device. Finally, the assembled device is fixedly installed onto the gas storage cylinder 5 by connecting the connecting base 2 to the drain outlet 501 via a threaded connection.

[0045] When the electric push rod 1 extends the push rod 103 to its farthest position, the sealing gasket 401 at the end of the connecting rod 4 seals the drain hole 202 inside the connecting base 2, and the air pressure inside the air storage cylinder 5 squeezes the sealing gasket 401 to adhere to the inner wall of the drain hole 202. When it is necessary to drain the water accumulated inside the air storage cylinder 5, the personnel supply power to the electric push rod 1 through the power cord 101. The electric push rod 1 drives the connecting rod 4 to retract through the push rod 103 at its end, so that the connecting rod 4 moves the sealing gasket 401 into the air storage cylinder 1, thereby releasing the seal of the sealing gasket 401 on the drain hole 202. The water inside the air storage cylinder 5 flows into the connecting base 2 through the water outlet holes 301 on both sides of the connecting sleeve 3, so that the water can be discharged from the drain hole 202.

[0046] If the electric push rod 1 malfunctions and cannot operate, personnel can tilt the pull ring 601 upwards to bend the rubber sealing gasket 401 and connecting rod 4 connected to the end of the metal rod 6, so that the sealing gasket 401 can be raised at a certain angle, creating a gap between the sealing gasket 401 and the inner wall of the connecting base 2. The air pressure inside the air storage cylinder 5 will force water through the gap into the drain hole 202, thus allowing the water inside the air storage cylinder 5 to flow out.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
