Description

Technical Field

[0001] The utility model relates to the field of electromagnetic valves, in particular to a heat exchange electromagnetic valve. Background Art

[0002] When the solenoid valve of the prior art is used in an environment with a relatively high ambient temperature, the temperature of the solenoid valve will continue to rise due to high-temperature heat transfer, causing the solenoid coil to overheat and be damaged. In the existing method, one can only first require to stay away from high temperature and increase the distance between the solenoid valve and the heating system so that the heat does not directly contact the solenoid valve. Although it can barely cope with it, it has high space requirements and a certain distance must be left; although the solenoid valve is not in direct contact with the heating system, under the influence of high temperature, the surrounding ambient temperature will be very high, which will also have a certain impact on the solenoid valve. Some manufacturers also use radiators to solve the impact of the high-temperature medium of the solenoid valve on the solenoid valve coil. This method is costly. Although it can solve some problems, the coil cannot resist the high temperature and fails when working in high-temperature medium and high-temperature environment for a long time.

[0003] In the prior art, since high temperature and low temperature are exchanged under the action of the heat exchanger, the medium that finally comes out is at the specified temperature requirement, and ultimately a solenoid valve is required to operate and execute. The existing solenoid valve cannot achieve temperature balance of the medium. Utility Model Content

[0036] See also Figures 1 to 7 The utility model provides a heat exchange solenoid valve, comprising a valve body 1 with a circulation function and an electromagnetic component 2.

[0037] See also Figures 2 to 5The valve body 1 is provided with a medium circulation inlet 101 and a medium circulation outlet 102, which are connected to each other and form a medium circulation channel 103 therebetween. The valve body 1 is provided with a medium outlet 104 and an installation cavity 105, which is used to install the electromagnetic assembly 2, and the installation cavity 105 is connected to the medium circulation channel 103, and the medium outlet 104 is connected to the installation cavity 105 through the pilot valve port 106.

[0038] See also Figure 1 The electromagnetic assembly 2 is threadedly connected in the installation cavity 105 and is used to open or close the pilot valve port 106 so that the medium outlet 104 is connected or disconnected with the medium circulation inlet 101.

[0039] In some embodiments, Figures 2 to 5 As shown, the axis of the medium circulation inlet 101, the axis of the medium circulation outlet 102 and the axis of the installation cavity 105 are perpendicular to each other, and the medium circulation channel 103 is L-shaped. The axis of the pilot valve port 106 coincides with the axis of the installation cavity 105, and the installation cavity 105 is arranged close to the medium circulation channel 103, and the medium circulation channel 103 is connected to the installation cavity 105 through the guide port 107. The axis of the medium outlet 104 is arranged parallel to the axis of the medium circulation inlet 101. This structure can make the valve body structure compact while meeting the functions. Among them, in order to simplify the structure, the valve body 1 adopts an integrated structure.

[0040] In some embodiments, Figure 3 As shown, the end of the valve body 1 has a mounting plane 108, and mounting holes 109 are symmetrically arranged on both sides of the mounting plane 108. With this structure, the valve body 1 can be mounted on external equipment using fasteners; one side of the valve body adopts a veneer type, which can be directly mounted on the heating system, does not occupy space, has low cost, and is easy to install.

[0041] In some embodiments, Figure 1 As shown, a sealing ring 3 is installed between the electromagnetic assembly 2 and the valve body 1. This structure is conducive to ensuring the sealing performance.

[0042] In some embodiments, Figure 1As shown, the electromagnetic assembly 2 includes a magnetic isolation tube assembly 21 threadedly connected in the installation cavity 105, a movable iron core 22 slidably installed in the magnetic isolation tube assembly 21, and a coil 23 installed outside the magnetic isolation tube assembly 21. The end of the movable iron core 22 facing the pilot valve port 106 is installed with a valve port seal 24, and the valve port seal 24 can be placed on the pilot valve port 106 to close the pilot valve port 106. A spring 25 is installed between the movable iron core 22 and the magnetic isolation tube assembly 21, and a spring groove 221 is provided at one end of the movable iron core 22 away from the pilot valve port 106. One end of the spring 25 is placed in the spring groove 221, and the other end is placed on the magnetic isolation tube assembly 21. The spring 25 always makes the movable iron core 22 have a tendency to move toward the pilot valve port 106. A first guide groove 222 and a second guide groove 223 are connected to each other in the movable iron core 22 . The first guide groove 222 and the second guide groove 223 are perpendicular to each other. One end of the second guide groove 223 is connected to the spring groove 221 .

[0043] like Figure 7 As shown, when the solenoid valve needs to be installed next to the high-temperature heating system and there is no extra space to separate the solenoid valve from the high-temperature heating system, the solenoid valve adopts a circulating passage design to open the medium circulation inlet 101 and the medium circulation outlet 102, and the external cooling system can continuously provide a cooling source for the solenoid valve. When the solenoid valve is in direct contact with the high-temperature heating system, the high temperature of the heating system will be quickly transferred to the solenoid valve, causing the temperature of the solenoid valve to gradually rise. The maximum high temperature that the solenoid valve can withstand is not more than 180°C. At this time, the external circulating coolant (gas) will continue to cool the solenoid valve. When the internal water and steam combine to produce water vapor, the medium outlet can be opened to discharge the excess gas, so that the solenoid valve can be operated safely. At the same time, hot and cold water can also be used in other equipment that requires temperature media, killing two birds with one stone.

[0044] like Figure 6 As shown, the solenoid valve is applied to the scene in the heat exchanger. When the water in the heat exchanger is heated under high-temperature steam, it is transported to the medium circulation inlet 101 of the solenoid valve through the circulation pipeline and then flows out from the medium circulation outlet 102 back to the heat exchanger. When the set temperature is reached, the solenoid valve is opened and the medium flows out from the medium outlet 104. At this time, the medium temperature is very accurate.

[0045] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0046] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
