Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a solenoid valve and a water cooling device thereof. Background Art

[0002] High temperature solenoid valve is a kind of pilot direct-acting solenoid valve, which is widely used in places such as shipbuilding heavy industry, testing equipment, heating equipment, hydraulic equipment, etc., and is used in heat transfer systems with working temperature above 300℃. In the production process of molecular sieve raw powder, with the continuous improvement of the process, the steam heating has gradually changed to automatic control heating, and solenoid valves are also used on steam pipelines. Due to the high temperature of steam and the long heating time, the solenoid valve is exposed to high temperature radiation baking when working in a high temperature environment, causing the magnetic force of the electromagnetic coil to decrease or fail, which will cause the solenoid valve to stop working indirectly, and the production process requirements cannot be met, and the product quality is affected to a certain extent.

[0003] In the face of the above problems, the Chinese utility model patent with the authorization announcement number CN 206246793 U discloses a high-temperature solenoid valve, including a valve body, an electromagnetic generator is arranged on the valve body, the electromagnetic generator and the valve body are connected by a connecting pipe, a valve stem is arranged in the connecting pipe, a valve core is arranged at the lower end of the valve stem, a magnet is arranged at the upper end of the valve stem, and an electromagnetic coil group is arranged in the inner cavity of the solenoid valve generator. A heat sink is arranged on the outer wall of the connecting pipe, and the heat dissipation of the valve body is carried out through the heat sink, so that the temperature of the valve body does not exceed the critical value, which effectively protects the valve body and saves the use cost. However, in the production process of molecular sieve raw powder, the temperature of the steam in the valve body is relatively high, and the steam passing time is relatively long. Only the heat sink can no longer meet the use requirements, so it is necessary to provide a solenoid valve with better heat dissipation effect. Utility Model Content

[0018] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0019] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] An embodiment of a solenoid valve of the utility model, as Figure 1-Figure 2 As shown, it includes a valve body 1, the valve body has a valve cavity, and the valve cavity has a steam inlet 13 and a steam outlet 14. An electromagnetic generator 2 and a water-cooling heat dissipation device are arranged on the valve body. The water-cooling heat dissipation device includes a connecting pipe 3, one end of the connecting pipe 3 is connected to the valve body 1, and the other end is connected to the electromagnetic generator 2. A valve stem 11 is arranged in the connecting pipe 3, one end of the valve stem is provided with a valve core 12, and the other end is provided with a magnet. An electromagnetic coil group is arranged in the inner cavity of the electromagnetic generator, and the electromagnetic coil group drives the valve stem-valve core to open and close the valve cavity through the action of the magnet. A plurality of heat sinks 4 are arranged at intervals on the outer wall surface of the connecting pipe 3 along its axial direction. The structures of the valve body, the electromagnetic generator, the connecting pipe and the heat sink, the valve stem and the valve core are all prior art, and the above structure and the working principle of the opening and closing of the electromagnetic valve are not described in detail in this embodiment.

[0021] In this embodiment, in order to increase the heat dissipation effect, a water-cooled heat dissipation pipe 5 is arranged on the heat sink 4, and the water-cooled heat dissipation pipe 5 includes an annular pipe section 6 wound between any two adjacent heat sinks 4 and a connecting pipe section 7 connecting the two adjacent annular pipe sections. The outer wall surface of the annular pipe section 6 contacts the outer wall surface of the connecting pipe 3 and / or the heat sinks 4 on both sides thereof, which can achieve better heat dissipation. The annular pipe section located at one end along the axis direction of the connecting pipe has a circulating water inlet 10, and the annular pipe section located at the other end has a circulating water outlet 9. The water-cooled heat dissipation pipe 5 is a continuous spiral structure. In this embodiment, each heat sink located between the heat sinks at both ends is provided with a mounting groove 8 for the connecting pipe section 7 to be installed. The outer wall surface of the connecting pipe section contacts the groove wall of the mounting groove to increase heat dissipation. Moreover, such a setting can simplify the structure of the water-cooled heat dissipation pipe, and at the same time, the water-cooled heat dissipation pipe is close to the pipe wall of the connecting pipe and the surface of the heat sink, ensuring the heat dissipation effect. The water-cooled heat dissipation pipe 5 adopts a copper tube, which has a good heat dissipation effect. In other embodiments, aluminum tubes or metal tubes of other materials can also be used.

[0022] The original heat sink is made of aluminum. Although it has a certain heat dissipation effect, it cannot protect the normal operation of the electromagnetic coil due to the poor use environment and high temperature. In this embodiment, a copper water-cooled heat pipe is added to the original heat sink. The copper pipe is bypassed in each channel in the middle of the heat sink. The two ends of the copper pipe are respectively connected to the water inlet and outlet systems. The heat radiated to the electromagnetic coil is taken away by the operation of cold water circulation. Specifically, the principle of cold water circulation is used to conduct the heat on the heat sink to the copper pipe, and the heat of the copper pipe is then conducted to the cold water in the pipe. During the circulation process, the cold water continuously takes away the residual heat of the copper pipe and the heat sink. Through such a process, it is ensured that the electromagnetic coil can always work and operate under low temperature. The formation of this structure will not be affected by environmental factors and can operate normally. Experiments have proved that the design of the water ring radiator of the solenoid valve effectively solves the problem that the solenoid valve cannot be used normally under high temperature conditions, achieves the expected purpose, and the product quality is also effectively guaranteed.
