Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, and in particular to a temperature solenoid control valve. Background Art

[0002] In the field of fluid control, the solenoid valve is a control component that controls whether the flow path is open or not. The solenoid valve includes a valve body, a solenoid coil and an electromagnet inner column. During production, the electromagnet inner column needs to be assembled and fixed to the valve body, and then the solenoid coil needs to be assembled and fixed to the electromagnet inner column.

[0003] The basic working principle of the solenoid valve is that when the power is on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, the spring presses the closing member onto the valve seat, and the valve closes.

[0004] After searching, the applicant found some typical prior arts, such as the solenoid valves involved in the Chinese invention patents with application numbers CN 117967793 A, CN118775613A and CN 118462897B. They need to use solenoid valves in the process of liquid transportation, but the existing solenoid valves cannot protect the solenoid valves during use. The valve core of the solenoid valve is prone to reduced sealing due to impurities after long-term use, affecting the closure of the valve core. It does not have the ability to remove impurities at the valve core. In order to facilitate the removal of impurities at the valve core and increase the service life of the valve core, we propose a temperature solenoid control valve. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a temperature electromagnetic control valve. After long-term use, impurities remain in the valve core, and the impurities will affect the sealing closure of the valve core. At this time, the pressure relief sleeve can be opened, and the pressure relief sleeve can remove the impurities in the valve core, thereby preventing the impurities from affecting the sealing of the valve core, solving the background problem. The specific technical solution is as follows:

[0006] A temperature electromagnetic control valve comprises a valve body shell, a valve tube is inserted into the top of the valve body shell, a circulation channel is formed between the valve tube and the valve body shell, a valve core assembly is fixedly assembled inside the valve tube, the valve core assembly comprises a wire core, an energized coil is wound on the outer surface of the wire core, a fixed iron core is fixedly connected inside the wire core, a fixing ring is fixedly assembled inside the valve tube, a valve stem is slidably assembled on the fixing ring, a moving iron core is fixedly connected to the top of the valve stem, a piston is fixedly sleeved on the outer surface of the valve stem, a spring is assembled between the piston and the fixing ring, the spring is sleeved on the outer surface of the valve stem, a valve column is fixedly connected to the bottom of the piston, a valve core is fixedly sleeved on the outer surface of the valve column, a protective sleeve is spirally screwed on the outer surface of the valve body shell, a top cover is fixedly connected to the top of the protective sleeve, a pressure relief pipe is fixedly connected to the bottom of the valve body shell, a pressure relief sleeve is threadedly screwed on the bottom of the pressure relief pipe, a top column is fixedly connected to the top of the pressure relief sleeve, and the top column extends into the circulation channel.

[0007] As a further feature of the present application, a positioning shell is integrally connected to the valve body shell, a positioning sleeve is threadedly screwed on the positioning shell, a positioning column is fixedly connected to the positioning sleeve, a positioning bar hole is opened on the valve tube, and the positioning column abuts against the positioning bar hole.

[0008] As a further feature of the present application, a first assembly groove is formed on the fixing ring, a first sealing ring is installed on the first assembly groove, and a second assembly groove is formed on the piston, a second sealing ring is installed on the second assembly groove.

[0009] As a further feature of the present application, a plurality of third assembly grooves are provided on the pressure relief sleeve, and a third sealing ring is installed on the third assembly groove.

[0010] As a further feature of the present application, a sealing groove is provided on the positioning sleeve, and a rubber sealing ring is installed on the sealing groove.

[0011] As a further feature of the present application, first flanges are fixedly welded at both ends of the valve body shell, a filter tube is arranged on the left side of the valve body shell, second flanges are fixedly welded at both ends of the left and right ends of the filter tube, a plurality of fastening bolts are bolted between the second flange on the right and the first flange on the left, a mounting sleeve is integrally connected to the filter tube, a filter sleeve is installed inside the mounting sleeve, a plurality of filter holes are provided on the filter sleeve, a fastening sleeve is threadedly connected to the top of the mounting sleeve, and an external hexagonal nut is integrally connected to the top of the fastening sleeve.

[0012] As a further feature of the present application, a sealing gasket is installed between the filter sleeve and the fastening sleeve.

[0013] As a further feature of the present application, a rubber gasket is installed between the first flange and the second flange.

[0014] The present invention provides a temperature electromagnetic control valve. Compared with the prior art, it has the following beneficial effects:

[0015] 1. This new type of assembly structure is a compact solenoid valve. When assembling this temperature solenoid control valve, first assemble the valve tube to the top of the valve body shell, and then assemble the valve core assembly into the valve tube. The valve core assembly consists of a wire core, an energized coil, a fixed iron core, a fixed ring, a valve stem, a moving iron core, a piston, a spring, a valve column and a valve core. Then, the protective cover and the fixed cover are assembled to the top of the valve body shell. When the valve body is normally supplied with fluid, the valve core is located below the valve tube under the action of the spring, and the valve core will not intercept the flow channel. When the energized coil is energized, the wire core and the fixed iron core will generate magnetic attraction. At this time, the magnetic attraction generated will be greater than the force of the spring. At this time, the valve core will move upward, and the valve core will intercept the flow channel, thereby realizing fluid on and off. After long-term use, impurities will remain at the valve core, and the impurities will affect the sealing closure of the valve core. At this time, the pressure relief sleeve can be opened, and the pressure relief sleeve can remove impurities at the valve core, thereby preventing impurities from affecting the sealing of the valve core.

[0016] 2. The new type of compact solenoid valve has a detachable filter tube, which is not an integrated fixed structure. It is convenient for personnel to choose whether to use the filter tube according to actual needs. The filter sleeve in the filter tube can process impurities in the fluid to prevent impurities from affecting the closure of the valve core. BRIEF DESCRIPTION OF THE DRAWINGS
