[0021] 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.

[0022] Reference Figures 1 - 4 The utility model provides an embodiment: a cooling device for a valve reducer, comprising a valve reducer body 1, a cooling assembly 2 is arranged on the outer side of the valve reducer body 1, the cooling assembly 2 comprises a cooling shell 201, a cylindrical cavity is arranged in the cooling shell 201, the cylindrical cavity is communicated with a heat dissipation pipe 209, a contact shell 1 205 and a contact shell 2 206 are fixedly connected to the cooling shell 201, the contact shell 206 is located above the contact shell 1 205, the contact shell 1 205 and the contact shell 2 206 are both in contact with the side wall of the valve reducer body 1, and a clearance port 204 is arranged on the contact shell 206;

[0023] The cooling liquid can be injected into the contact shell 1 205 and the contact shell 2 206 , and the heat on the valve reducer body 1 can be taken away by heat conduction between the contact shell 1 205 and the contact shell 2 206 , thereby achieving a cooling effect.

[0024] The cooling shell 201 is fixedly connected with a heat dissipation pipe 209, and a cover is provided at the end of the heat dissipation pipe 209, and the cover is threadedly connected to the heat dissipation pipe 209. A piston head 2081 is slidably connected in the heat dissipation pipe 209, and a piston rod 208 is fixedly connected to the piston head 2081. The end of the piston rod 208 is fixedly connected to the control handle 207. A heat dissipation fin 210 is fixedly connected to the heat dissipation pipe 209. The shape of the heat dissipation fin 210 is circular. There are multiple heat dissipation fins 210, which are evenly arranged. 10 is provided with a plurality of heat dissipation holes 211, which are evenly arranged around the circumference. The heat sink 210 and the heat dissipation holes 211 can dissipate heat, so that the coolant can be put back into cooling operation. A suction pipe 203 is fixedly connected to the cooling shell 201, and the suction pipe 203 is arranged on a side close to the connecting port 212. The end cover 202 is threadedly connected to the suction pipe 203. The cooling shell 201 is connected to the contact shell 1 205 and the contact shell 2 206 through the connecting port 212.

[0025] Through the provided cooling component 2, the valve speed reducer can be cooled down to avoid overheating of the valve speed reducer, ensuring a relatively long service life of the valve speed reducer. Moreover, the coolant can be transported through the piston head 2081, facilitating the addition and discharge of the coolant, with convenient operation. During the cooling operation, the end cover 202 is unscrewed, the suction pipe 203 is inserted into the container filled with the coolant, and then the control handle 207 drives the piston rod 208 and the piston head 2081 to move, generating negative pressure to suck the coolant into the interior. Then, the end cover 202 is closed, and the control handle 207 is pushed to reset the piston head 2081, injecting the sucked coolant into the contact housing one 205 and the contact housing two 206. By utilizing the heat conduction of the contact housing one 205 and the contact housing two 206, the heat on the valve speed reducer body 1 is taken away, thus playing a role in cooling. After cooling, the control handle 207 moves outward again to suck the heated coolant back into the heat dissipation pipe 209, and then heat dissipation is carried out through the heat dissipation fins 210 and the heat dissipation holes 211, enabling the coolant to be reused for the cooling operation.
