Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve core. Background Art
[0002] A solenoid valve is a device that uses electromagnetic principles to control the flow of fluids. It is mainly composed of an electromagnet, a valve core, a valve body, and a seal. When no power is supplied, the valve core blocks the passage of the valve body under the action of a spring, and the solenoid valve is in a closed state. When the coil is powered on, the coil generates a magnetic force, which causes the valve core to overcome the spring force and lift upward, opening the passage in the valve and placing the solenoid valve in a conducting state. In this way, the flow of fluids can be controlled by controlling the on and off current of the electromagnet.
[0003] The valve core of the solenoid valve is the core component of the solenoid valve. It plays the role of switching and controlling the fluid. The performance of the solenoid valve core spring directly affects the response speed and service life of the solenoid valve. The existing magnetic valve core spring is generally exposed. When the solenoid valve is in the on state, the fluid may enter and contact with the spring, thereby affecting the performance and life of the spring. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] A solenoid valve core, such as Figure 1-5 As shown, it includes a valve core 1, a housing 101, a retaining ring 102, a sealing ring 103, a spring 2, a blocking block 3 and a fixing screw 4. The bottom of the housing 101 is connected with a retaining ring 102, and the outer embedded sleeve of the retaining ring 102 is provided with a sealing ring 103. The housing 101 is movably provided with a valve core 1, and the bottom of the valve core 1 is connected with a blocking block 3 through a fixing screw 4, which is convenient for replacing the blocking block 3. The bottom of the blocking block 3 is a rubber structure to improve the sealing performance of the blocking block 3. The blocking block 3 is a concave structure, and the valve core 1 and the blocking block 3 are connected. The concave bottom surface is connected, and a spring 2 is arranged on the outside of the valve core 1. The bottom end of the spring 2 is connected to the outside of the lower part of the valve core 1, and the top end of the spring 2 contacts the retaining ring 102. The lower part of the spring 2 is located in the block 3, and a gap for the spring 2 to move is arranged between the outer side of the valve core 1 and the inner side of the block 3. A long groove 10 that passes through from top to bottom is opened on the outside of the valve core 1. The setting of the long groove 10 can ensure that the inside and outside of the shell 101 are in a connected state, so that the internal and external air pressures are in the same state, and ensure that the valve core 1 can move quickly in the shell 101.
[0022] like Figure 1-5 As shown, it also includes a protective sleeve 7 and a protrusion 9. A hollow groove 5 is opened on the blocking block 3. A thread 6 is arranged on the upper part of the protective sleeve 7. The protective sleeve 7 is connected to the bottom of the retaining ring 102 through the thread 6. The lower part of the protective sleeve 7 is located in the hollow groove 5. The valve core 1 and the spring 2 are both located in the protective sleeve 7. Five protrusions 9 are evenly spaced and connected to the outer side of the protective sleeve 7. The protrusions 9 facilitate the rotation of the protective sleeve 7.
[0023] like Figure 1-2 As shown, vertical grooves 8 are evenly spaced apart on the outer side of the housing 101 . The arrangement of the grooves 8 has an anti-slip effect, which facilitates the installation of the housing 101 .
[0024] When the solenoid valve core is installed on the solenoid valve, the retaining ring 102 is against the valve body, and the sealing ring 103 plays a sealing role to prevent the fluid from leaking from the gap between the valve body and the shell 101. The block 3 blocks the connecting port of the valve body. When the solenoid valve is energized, magnetism is generated, thereby adsorbing the valve core 1 into the shell 101, thereby driving the block 3 away from the connecting port of the valve body, that is, the block 3 no longer blocks the valve body, so that the fluid can pass through the valve body. At this time, the spring 2 is compressed, and the protective sleeve 7 moves adaptively in the hollow groove 5. In this way, the protective sleeve 7 protects the spring 2 at all times to prevent the fluid from entering and contacting the spring 2, thereby reducing the service life of the spring 2. When the protective sleeve 7 needs to be cleaned or replaced, the protective sleeve 7 is rotated by the protrusion 9 to remove the protective sleeve 7 from the retaining ring 102.
[0025] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
