Description

Technical Field

[0001] This utility model belongs to the field of control valve technology, specifically relating to a combined valve body structure. Background Technology

[0002] A solenoid valve is an electromagnetically controlled industrial device, a fundamental component of automation used to control fluids. It belongs to the category of control elements and is used to control actuators. It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Its working principle is to control the mechanical movement of the valve core by controlling the on / off state of the electromagnet, thereby closing or opening the vent orifice to control certain parameters of the fluid entering the mechanical component.

[0003] Currently, most conventional solenoid valve core assemblies use simple bolts and nuts to fix the housing and base together, ensuring a certain level of sealing and facilitating easy assembly and disassembly. However, in actual use, solenoid valves are often installed near water sources in high-humidity areas. Moisture can easily seep into the housing through the sealing joints of the solenoid valve core assembly and the wiring connection holes between the solenoid valve core assembly and the external controller, causing corrosion of the solenoid valve core assembly. This can damage the solenoid valve control components and affect the normal operation of the valve. Therefore, regular maintenance or replacement is necessary.

[0004] To this end, the applicant has conducted beneficial explorations and attempts, and found a solution to the above problems. The technical solution to be introduced below was developed in this context. Summary of the Invention

[0031] The following examples, in conjunction with the appendix, illustrate the concepts. Figures 1-9 The structure is shown below, and the technical solution of this utility model will be further described in detail.

[0032] Example 1: A combined valve body structure includes a main valve body 1 and a sub-valve body 2 disposed on the main valve body 1. The sub-valve body 2 is provided with an electromagnetic coil part 201. A plunger hole 202 is opened inward on the side of the sub-valve body 2 connected to the main valve body 1. A valve core driving plunger 203 is movably disposed in the plunger hole 202. A pusher 204 is provided at the end of the valve core driving plunger 203 near the main valve body 1. A valve core assembly 3 is disposed between the main valve body 1 and the sub-valve body 2. An air inlet channel 101 is opened on the lower side of the valve core assembly 3 and in the main valve body 1. An air outlet channel 102 is opened on the outer side below the valve core assembly 3 and in the main valve body 1.

[0033] A valve core hole 103 is provided on one side of the main valve body 1 that connects to the sub-valve body 2. The air intake channel 101 is located at the center of the bottom of the valve core hole 103. A limit hole 205 is provided on one side of the sub-valve body 2 that connects to the main valve body 1. The valve core assembly 3 includes a valve core element 301 and a sealing top post 302. A positioning ring 303 is provided at one end of the valve core element 301 near the sub-valve body 2. The lower surface of the positioning ring 303 is the valve core element positioning surface 304. The valve core element 301 is installed in the valve core hole 103. The positioning ring 303... 3. The valve body 2 is pressed onto the surface of the main valve body 1. The sub-valve body 2 is pressed onto the positioning ring 303 through the limiting hole 205. The main valve body 1 and the sub-valve body 2 are close to each other. The valve core 301 has a plunger channel 305 in the center. A push pin hole 306 is opened on the inner side of the plunger channel 305. The push pin 204 is located inside the push pin hole 306 and moves. The sealing top pin 302 is located on the side of the valve core 301 away from the sub-valve body 2. The sealing top pin 302 is located between the push pin hole 306 and the air intake channel 101.

[0034] The specific implementation method is as follows:

[0035] During assembly, the valve core 301 is installed in the valve core hole 103, and the positioning ring 303 is pressed onto the surface of the main valve body 1. The valve core positioning surface 304 of the positioning ring 303 positions the entire valve core 301. Through the cooperation between the sub-valve body 2, the valve core 301, the valve core drive plunger 203, and the sealing top column 302, quick assembly is achieved, and each component can be quickly replaced and repaired.

[0036] Furthermore, when the structure of the main valve body 1 is an existing product, the structure of the valve core 301 in this embodiment can match the existing main valve body 1, improving the practicality of product maintenance and replacement;

[0037] The valve core drive plunger 203 is controlled by the electromagnetic coil 201, causing the valve core drive plunger 203 to move within the plunger hole 202. The movement of the valve core drive plunger 203 causes the pusher 204 to press against or release the sealing top post 302, thereby realizing the opening and closing function between the air intake channel 101 and the air outlet channel 102.

[0038] Example 2:

[0039] Based on Embodiment 1, this embodiment further defines that the valve core 301 is provided with a plurality of top pillar retaining rings 307 arranged in a ring at the end away from the positioning ring 303, the sealing top pillar 302 is provided inside the plurality of top pillar retaining rings 307, and the inner side of the end of the top pillar retaining ring 307 away from the valve core 301 is provided as an inclined surface 311.

[0040] Among them, a plunger elastic element 206 is provided between the end of the valve core driving plunger 203 away from the pusher 204 and the sub-valve body 2, and a top column elastic element 308 is provided between the sealing top column 302 and the air intake channel 101.

[0041] The ring-shaped arrangement of several top pillars and rings 307 forms a circular ring, encircling the sealing top pillar 302 on its inner side, allowing the sealing top pillar 302 to move only in a directional manner. The inclined surface 311 acts as a guide and can expand the air outlet area. Gas enters from the air inlet channel 101 into the inner side of the valve core hole 103, and then flows through the gap between two adjacent top pillars and rings 307 to the air outlet channel 102. The plunger elastic element 206 provides real-time support for the valve core drive plunger 203, enabling the valve core drive plunger 203 to push the sealing top pillar 302 without the force applied by the electromagnetic coil part 201, thus achieving the purpose of closure. The top pillar elastic element 308 can push the sealing top pillar 302 outward, thus ensuring smooth airflow.

[0042] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again.

[0043] Example 3:

[0044] Based on Example 2, this embodiment further specifies that both the plunger elastic element 206 and the top column elastic element 308 are spring elements, which can effectively apply elastic force to the sealing top column 302 and the valve core driving plunger 203.

[0045] The other parts of this embodiment are the same as those in Embodiment 2 above, and will not be described again.

[0046] Example 4:

[0047] Based on Example 2, this embodiment further specifies that a sealing ring 309 is embedded in the middle of the valve core 301. The sealing ring serves to prevent side leakage when air is vented and makes the valve core 301 more stable to install.

[0048] The other parts of this embodiment are the same as those in Embodiment 2 above, and will not be described again.

[0049] Example 5:

[0050] This embodiment further defines, based on embodiment 4, that a tapered boss 310 is provided between several top column retaining rings 307 and at the opening of the push column hole 306.

[0051] When the sealing top post 302 moves toward the conical boss 310, the sealing top post 302 and the conical boss 310 are connected by the force exerted by the top post elastic element 308, which causes the sealing top post 302 to block the push post hole 306, thus achieving the function of external sealing.

[0052] The other parts of this embodiment are the same as those in Embodiment 4 above, and will not be described again.

[0053] Example 6:

[0054] Based on embodiment 2, this embodiment further specifies that the sub-valve body 2 has an air outlet 207 on the side near the main valve body 1. The air outlet 207 penetrates both sides of the limiting hole 205, and the opening depth of the air outlet 207 is greater than the opening depth of the limiting hole 205.

[0055] The air outlet 207 is designed so that the air pressure generated when the valve core drives the plunger 203 moves is discharged to the outside through the air outlet 207, which is more conducive to the operation of the valve core driving the plunger 203.

[0056] The other parts of this embodiment are the same as those in Embodiment 2 above, and will not be described again.

[0057] Example 7:

[0058] This embodiment further defines, based on embodiment 1, that the main valve body 1 is provided with a positioning hole 104 and several threaded holes 105 on the side where it connects to the sub-valve body 2, the sub-valve body 2 is provided with a positioning pin 209 corresponding to the position of the positioning hole 104 on the side near the main valve body 1, and the sub-valve body 2 is provided with several bolt holes 208 corresponding to the positions of the threaded holes 105. The main valve body 1 and the sub-valve body 2 are connected by bolts in the bolt holes 208 and connected by the threaded holes 105.

[0059] The fit between the positioning pin 209 and the positioning hole 104 accelerates the accuracy of the installation and enables a quick and detachable connection between the main valve body 1 and the sub-valve body 2.

[0060] The other parts of this embodiment are the same as those in Embodiment 1 above, and will not be described again.

[0061] Example 8:

[0062] Based on any one of embodiments 1-7, this embodiment further specifies that the main valve body 1 can be configured as a long strip-shaped main valve body 4 formed by connecting several main valve bodies 1 together, and the long strip-shaped main valve body 4 is correspondingly matched with sub-valve bodies 2.

[0063] The elongated main valve body 4 is designed to suit different industrial environments, enhancing its practicality.

[0064] The other parts of this embodiment are the same as any one of the embodiments 1-7 above, and will not be described again.

[0065] The overall working principle of this utility model is as follows:

[0066] The assembly is detachable. The valve core 301 is installed in the valve core hole 103, and the positioning ring 303 is pressed onto the surface of the main valve body 1. The valve core positioning surface 304 of the positioning ring 303 positions the entire valve core 301. The fit between the positioning pin 209 and the positioning hole 104 speeds up the installation accuracy. The main valve body 1 and the sub-valve body 2 are connected by bolts in the bolt hole 208 and threaded hole 105. The assembly is complete.

[0067] During use, the valve core drive plunger 203 is controlled by the electromagnetic coil 201, causing the valve core drive plunger 203 to move within the plunger hole 202. The movement of the valve core drive plunger 203 causes the pusher 204 to press against or release the sealing top post 302. The several top post retaining rings 307 arranged in a ring form a circle, encircling the sealing top post 302 on its inner side, so that the sealing top post 302 can only move in a directional manner. The inclined surface 311 plays a guiding role, and the inclined surface 311 can expand the air outlet surface. Gas enters from the intake channel 101 into the inner side of the valve core hole 103, and then flows through the gap between two adjacent top column retaining rings 307 to the outlet channel 102. The plunger elastic element 206 provides real-time support for the valve core drive plunger 203, so that the valve core drive plunger 203 can hold the sealing top column 302 without the force of the electromagnetic coil part 201, thus achieving the purpose of closing. The top column elastic element 308 can push the sealing top column 302 outward, thus achieving the function of unobstructed airflow.

[0068] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
