Description

Technical Field

[0001] The utility model relates to the technical field of magnetic isolation pipe seats, in particular to a magnetic isolation pipe seat structure of a diaphragm type electromagnetic valve. Background Art

[0002] The diaphragm solenoid valve is an electromagnetically controlled automation basic component that controls the opening and closing of the valve by powering on or off. It is widely used in various automatic control systems, such as water treatment, air conditioning, chemical industry and other industries. This type of solenoid valve is characterized by compact structure, good sealing, sensitive action, stable performance, easy installation and simple maintenance. Its working principle is to use the electromagnetic coil to generate a magnetic field to drive the valve core to move up and down, thereby changing the flow state of the fluid.

[0003] The magnetic isolation pipe seat is an important component of the diaphragm solenoid valve. After searching, a solenoid valve is disclosed on the Chinese Patent Network, and the announcement number is CN218992519U. According to the records in the comparative documents, the fixed iron core is fixedly installed to the valve body through the magnetic isolation pipe seat, and according to the attached Figure 1 As far as we know, the fixed iron core and the magnetic isolation tube seat in the comparative document are of integrated design, which makes it inconvenient to disassemble and maintain the fixed iron core and the magnetic isolation tube seat, and is inconvenient to use.

[0004] Therefore, a diaphragm type solenoid valve magnetic isolation pipe seat structure is proposed. Utility Model Content

[0005] The utility model aims to provide a magnetic isolation pipe seat structure of a diaphragm type solenoid valve.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A diaphragm type solenoid valve magnetic isolation pipe seat structure, comprising:

[0008] Magnetic isolation pipe holder body;

[0009] The outer wall of the magnetic isolation tube seat body is provided with a connecting ear;

[0010] A pipe is fixed on the top of the magnetic isolation pipe seat body, and a fixed iron core is connected inside the pipe;

[0011] The inner wall of the pipe is provided with a first internal thread, and the outer wall of the fixed iron core is provided with an external thread matching the first internal thread;

[0012] The fixed iron core is threadably connected to the interior of the pipeline through external threads cooperating with the first internal threads.

[0013] Preferably, a sealing ring is connected to the outer wall of the fixed iron core, and the bottom of the sealing ring abuts against the top of the pipeline.

[0014] Preferably, a second internal thread is provided on the inner wall of the sealing ring, and the sealing ring is threadably connected to the outer wall of the fixed iron core through the second internal thread and the external thread.

[0015] Preferably, the top of the magnetic isolation tube seat body is symmetrically provided with connection grooves, a vertical bar is connected in the connection groove, and a first clamping column and a second clamping column are fixed to one end of the vertical bar close to the fixed iron core;

[0016] A first clamping hole is provided on the outer wall of the fixed iron core, and a second clamping hole is provided on the outer wall of the sealing ring.

[0017] Preferably, one end of the first clamping column is clamped in the first clamping hole, and one end of the second clamping column is clamped in the second clamping hole.

[0018] Preferably, a fixing ear is fixed to one end of the vertical bar, a third clamping hole is opened at one end of the fixing ear, and a fourth clamping hole matching with the third clamping hole is opened on the inner wall of the connecting groove;

[0019] The third clamping hole and the fourth clamping hole are clamped with a third clamping column.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] Since the fixed iron core is threadedly connected to the inside of the pipe by means of an external thread cooperating with the first internal thread, the fixed iron core can be taken out from the pipe inside the magnetic isolation pipe seat body by only rotating the fixed iron core in the opposite direction along the threaded connection direction of the external thread and the first internal thread. Compared with the existing ones, the utility model makes it easy to disassemble the fixed iron core by changing the connection method between the fixed iron core and the pipe of the magnetic isolation pipe seat body, thereby facilitating the disassembly and maintenance of the fixed iron core and the magnetic isolation pipe seat body, and is more convenient to use.

[0022] The utility model fixes the vertical bar by placing the vertical bar into the connecting groove, and then respectively clamping the first clamping column and the second clamping column on the outer wall of the vertical bar into the first clamping hole and the second clamping hole, and then clamping the third clamping column into the third clamping hole and the fourth clamping hole. Then, the vertical bar cooperates with the first clamping column and the second clamping column to limit the fixed iron core and the sealing ring to prevent them from rotating or loosening, thereby improving the stability of the fixed iron core and the sealing ring.

[0032] Specifically, since the fixed iron core 4 is threadedly connected to the inside of the pipe 3 through the external thread 6 and the first internal thread 5, the fixed iron core 4 can be taken out from the inside of the pipe 3 of the magnetic isolation pipe seat body 1 by simply rotating the fixed iron core 4 in the opposite direction along the threaded connection direction of the external thread 6 and the first internal thread 5. Compared with the existing ones, the utility model changes the connection mode between the fixed iron core 4 and the pipe 3 of the magnetic isolation pipe seat body 1, so that the fixed iron core 4 is easy to disassemble, thereby facilitating the disassembly and maintenance of the fixed iron core 4 and the magnetic isolation pipe seat body 1, and is more convenient to use;

[0033] Since the sealing ring 7 is threadedly connected to the outer wall of the fixed core 4 through the second internal thread 8 and the external thread 6 , the sealing ring 7 can improve the sealing and stability of the connection between the fixed core 4 and the pipeline 3 .
