Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a remote control mechanism of a ceramic ball valve. Background Art

[0002] The remote control mechanism of the ceramic ball valve usually adopts an electric actuator. The electric actuator can automatically open, close or adjust the valve by receiving the remote control signal, thereby realizing remote control and automatic operation. The electric actuator can realize automatic control of the ceramic ball valve, and quickly open, close or adjust the valve through electrical signals or control system instructions. Through the electric actuator, the opening of the ceramic ball valve can be accurately controlled to ensure that the valve stays at the required position, thereby accurately adjusting the flow and pressure of the fluid;

[0003] Ceramic ball valves are usually used in corrosion-resistant, high-temperature, high-pressure or special media applications. Electric actuators can operate stably and reliably in these complex working environments and can quickly control the valve. When solid particles or impurities in the medium enter the valve, it is easy to cause the valve to get stuck. At this time, the electric actuator is susceptible to additional force and torque. This additional force can easily cause the internal components of the electric actuator to be overloaded and damaged. Therefore, we proposed a remote control mechanism for ceramic ball valves. Utility Model Content

[0004] The purpose of the utility model is to provide a remote control mechanism for a ceramic ball valve to solve the problem proposed in the above-mentioned background technology that when solid particles or impurities in the medium enter the interior of the valve, the valve may become stuck. At this time, the electric actuator may be susceptible to additional force and torque, which may easily cause the internal components of the electric actuator to be overloaded and damaged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a remote control mechanism for a ceramic ball valve, comprising a ceramic ball valve body and an electric actuator, the electric actuator is installed on the upper side of the ceramic ball valve body, and a valve stem is installed inside the ceramic ball valve body, the valve stem is fixed to the output end of the electric actuator, a first bevel gear is fixed to the outside of the valve stem, and the first bevel gear is connected to the second bevel gear, and a center rod is fixed to one side of the second bevel gear, one end of the center rod passes through one side of the electric actuator and is fixed to a handwheel, and a connecting layer is bonded to the outside of the center rod.

[0006] Preferably, a connection pad is bonded to a side of the electric actuator close to the connection layer, and an electromagnet is installed on a side of the electric actuator close to the connection pad.

[0007] Preferably, one end of the center rod close to the electromagnet is sleeved with a connecting spring, and one end of the connecting spring is fixed to the electric actuator.

[0008] Preferably, one end of the connecting spring away from the electromagnet is fixed to the connecting ring, and the connecting ring is movably connected to the central rod through a bearing.

[0010] Preferably, the connecting layer and the connecting pad are respectively made of rubber material, and the connecting layer and the connecting pad are extruded.

[0011] Compared with the prior art, the beneficial effect of the present utility model is that: for the remote control mechanism of this ceramic ball valve, when the electromagnet is powered off, the connecting spring is made to push the connecting ring to drive the central rod to move along the inner side of the electric actuator. At this time, the central rod drives the second bevel gear to fit with the first bevel gear under the action of the connecting spring.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 - 3 The utility model provides a technical solution: a remote control mechanism of a ceramic ball valve, comprising a ceramic ball valve body 1 and an electric actuator 101, the electric actuator 101 is installed on the upper side of the ceramic ball valve body 1, and a valve stem 102 is installed inside the ceramic ball valve body 1, the valve stem 102 is fixed to the output end of the electric actuator 101, a first bevel gear 2 is fixed to the outer side of the valve stem 102, and the first bevel gear 2 is connected to the second bevel gear 201, and a center rod 202 is fixed to one side of the second bevel gear 201, one end of the center rod 202 passes through one side of the electric actuator 101 and is fixed to a hand wheel 203, a connecting layer 204 is bonded to the outer side of the center rod 202, and a side of the electric actuator 101 close to the connecting layer 204 is bonded to A connecting pad 205 is provided, and an electromagnet 206 is installed on the side of the electric actuator 101 close to the connecting pad 205. A connecting spring 207 is sleeved on the end of the center rod 202 close to the electromagnet 206, and one end of the connecting spring 207 is fixed to the electric actuator 101, and the end of the connecting spring 207 away from the electromagnet 206 is fixed to a connecting ring 208, and the connecting ring 208 is movably connected to the center rod 202 through a bearing, and a magnetic ring 209 is fixed on the side of the connecting ring 208 close to the electromagnet 206, and the electromagnet 206 and the magnetic ring 209 are magnetically attracted, the connecting layer 204 and the connecting pad 205 are respectively made of rubber materials, and the connecting layer 204 and the connecting pad 205 are squeezed, and the first bevel gear 2 is meshed and docked with the second bevel gear 201.

[0019] In specific implementation, according to Figures 1 - 3, the remote control mechanism of the ceramic ball valve generally uses an electric actuator 101. The electric actuator 101 can quickly realize the remote control action of the ceramic ball valve body 1. When solid particles or impurities in the medium enter the inside of the ceramic ball valve body 1 and cause the valve to jam, at this time, the staff does not start the electric actuator 101 temporarily. First, cut off the power supply of the electromagnet 206. A ferrite plate or other plates can be installed outside the electromagnet 206, which can effectively absorb and shield electromagnetic waves, and prevent the magnetic waves of the electromagnet 206 from affecting the electric actuator 101. When the electromagnet 206 is powered off, the electromagnet 206 can lose its magnetism. At this time, the electromagnet 206 can be disengaged from the magnetic attraction of the magnetic ring 209. At this time, the connecting spring 207 can be extended, so that the connecting spring 207 pushes the connecting ring 208, and the connecting ring 208 drives the central rod 202 to move along the inside of the electric actuator 101. Then, since the connecting layer 204 and the connecting pad 205 are made of rubber materials and have a certain deformation ability, and the connecting layer 204 and the connecting pad 205 are pressed against each other, it is not easy for foreign objects to enter the inside of the electric actuator 101 when the central rod 202 moves. At this time, the central rod 202 drives the second bevel gear 201 to fit together with the first bevel gear 2 under the action of the connecting spring 207. At this time, the staff can rotate the handwheel 203, and the handwheel 203 drives the second bevel gear 201 to rotate through the central rod 202, so that the second bevel gear 201 can be meshed and docked with the first bevel gear 2. Continuing to rotate the handwheel 203, the second bevel gear 201 drives the first bevel gear 2 to rotate, so that the first bevel gear 2 can drive the valve stem 102 to rotate, and the valve stem 102 can drive the sphere of the ceramic ball valve body 1 to rotate, so that the electric actuator 101 is not easily affected by additional forces and torques, and the components inside the electric actuator 101 are not easily damaged due to overload.

[0020] In summary, when solid particles or impurities in the medium enter the inside of the ceramic ball valve body 1 and cause the valve to jam, do not start the electric actuator 101 temporarily. First, cut off the power supply of the electromagnet 206, so that the connecting spring 207 pushes the connecting ring 208 to drive the central rod 202 to move along the inside of the electric actuator 101. At this time, the central rod 202 drives the second bevel gear 201 to fit together with the first bevel gear 2 under the action of the connecting spring 207. Rotate the handwheel 203 so that the second bevel gear 201 can be meshed and docked with the first bevel gear 2. Continuing to rotate the handwheel 203, the second bevel gear 201 drives the first bevel gear 2 to rotate, so that the first bevel gear 2 can drive the valve stem 102 to rotate, and the valve stem 102 can drive the sphere of the ceramic ball valve body 1 to rotate, so that the electric actuator 101 is not easily affected by additional forces and torques, and the components inside the electric actuator 101 are not easily damaged due to overload.
