Abstract

[0001] The utility model relates to the technical field of high-temperature solenoid valves, in particular to a high-temperature solenoid valve. Background Art
[0002] With the development of industrial automation, solenoid valves are used as control elements in various fields, playing an increasingly important role. However, in high temperature environments, conventional battery valves are difficult to meet the needs of industrial production. In high temperature environments, the heat dissipation performance is poor, the solenoid coil is easily burned out, and operation failures occur. Therefore, a high-temperature solenoid valve is needed. When the solenoid valves on the market are operated, the coil is energized, the coil generates an electromagnetic drive to drive the valve core, and the valve core drives the piston to open the valve. The valve is switched on and off by turning the coil on and off. This design completely controls the valve core structure through the electromagnetic device to close the valve body. In this operation, when the electromagnetic device is no longer controlling the valve core structure, the valve will close slowly and loosely, and the valve cannot be closed quickly. It is also prone to side leakage and medium residue. Therefore, a high-temperature solenoid valve is provided. Utility Model Content

[0020] 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.
[0021] The utility model provides Figure 1-2A high-temperature solenoid valve shown includes a valve body 1, a plug body structure is arranged inside the valve body 1, a screw cover component 3 is arranged on the top outer ring of the valve body 1, a spring 301 is arranged at the bottom of the screw cover component 3 and the top of the plug body structure, a heat sink 4 is arranged on the top of the screw cover component 3, an electromagnetic device is arranged on the top of the heat sink 4, a valve core structure is inserted and connected inside the electromagnetic device, and the electromagnetic device controls the on and off of the valve body 1 by controlling the valve core structure.
[0022] It should be noted that the high-temperature solenoid valve adopts targeted sealing when passing through different media, which further improves the rationality of the solenoid valve. It adopts a stainless steel plug body structure, and the valve core wear can be automatically compensated, which further improves the life and reliability of the solenoid valve. It can work continuously and frequently. It adopts a novel and ingenious valve core structure and installs a heat dissipation device to make the structure more compact.
[0023] Specifically, a sealing ring 2 is provided between the top end of the valve body 1 and the bottom end of the rotary cover component 3 , and the sealing ring 2 is used for sealing the connection between the rotary cover component 3 and the valve body 1 .
[0024] It should be noted that the design of the valve body 1 refers to the model ZQDF, and the surface material is made of stainless steel, which has excellent resistance to high temperature, high pressure and corrosion. It uses a copper core coil, which has a better electromagnetic effect and a sensitive response. The valve body 1 is thickened and made of stainless steel, which has a high resistance to corrosion and acid, and is resistant to high temperature, oxidation and durability.
[0025] The specific valve core structure includes: a valve core component 5, which is arranged in the middle of the inner ring wall of the coil component 6; a guide rod 501, the top of which is arranged at the bottom of the valve core component 5, the bottom of the guide rod 501 passes through the middle of the rotary cover component 3 and the spring 301 and is connected to the inside of the valve body 1, and the bottom of the guide rod 501 is located at one end inside the valve body 1 for connecting to the plug body structure.
[0026] It should be noted that the pipeline should be fully flushed before taking over, and the metal powder sealing material residue, rust and other dirt in the pipeline should be completely removed; the working medium of the solenoid valve should be clean and free of particulate impurities. It is recommended to install a filter in front of the valve and a steam trap in the steam pipeline. The dirt on the surface of the internal parts of the water inlet solenoid valve and the filter must be cleaned regularly.
[0027] Specifically, the plug body structure includes: a valve plug 101, the top of the valve plug 101 passes through the middle of the spring 301 and is sleeved on the bottom of the guide rod 501;
[0028] The plug cavity 102 is opened in the middle of the inner wall of the valve body 1 , and the bottom of the valve plug 101 is inserted and connected in the plug cavity 102 .
[0029] It should be noted that during installation, the arrow on the valve body 1 should be consistent with the flow direction of the medium, and it should not be installed in a place with direct dripping or splashing water. The solenoid valve should be installed vertically upward. After the solenoid valve is installed, there should be no reverse pressure difference in the pipeline, and it needs to be powered on several times to make it suitable for temperature before it can be officially put into use. Before installing the solenoid valve, the pipeline should be thoroughly cleaned, the medium introduced should be free of impurities, and a filter should be installed before the valve.
[0030] Specifically, the outer annular wall of the heat sink 4 is provided with heat sink fins 401 .
[0031] It should be noted that the heat dissipation principle of the heat sink 401 is to increase the surface area to accelerate the heat dissipation. The larger the surface, the easier the air circulation. Do not install the solenoid valve in the concave part of the pipeline to prevent steam condensate, impurities, etc. from settling in the valve and hindering the action. In the case of insufficient rigidity of the pipeline, it is recommended to fix the front and rear pipes of the ZCZG high-temperature and high-pressure solenoid valve with brackets to prevent the solenoid valve from causing vibration when working.
[0032] Working principle of this utility model:
[0033] The high-temperature solenoid valve needs to be installed to control the flow position. According to the direction of medium flow, the water inlet chamber 104 and the water outlet chamber 103 are reasonably allocated. After the installation is complete, the coil is energized, and the medium will flow into and be stored in the water inlet chamber 104. When the coil is energized, a strong magnetic field will be generated in the ring, so that the valve core component 5 is attracted or pushed open under the action of the magnetic field. The guide rod 501 connected to the bottom of the valve core component 5 drives the valve plug 101 to also perform up and down reciprocating motion. The valve core moves upward to drive the guide rod 501 and the valve plug 101, and a pressure difference is generated in the closed space of the battery valve. The medium flows through the entire battery valve under the action of pressure. When the power is off, the magnetic field inside the battery valve dissipates, and the internal air pressure quickly returns. The valve plug 101 quickly returns to its original position under the force of the gas spring 301, so that the medium is prohibited from flowing.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
