Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, and in particular to a four-position five-way cut-off structure solenoid valve. Background Art

[0002] Solenoid valves are industrial devices controlled by electromagnetics. They are basic automation components used to control fluids and are classified as actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow, speed, and other parameters of media. Solenoid valves can be combined with various circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each serving different functions in a control system. The most commonly used are check valves, safety valves, directional control valves, and speed control valves. Traditional solenoid valves are typically single-unit solenoid valves, with a single internal cavity that can control only one actuator. Even single-unit solenoid valves capable of controlling multiple actuators can shut down if a component within the cavity fails. Summary of the Invention

[0003] In view of the current status of the above-mentioned prior art, the present invention provides a four-position five-way cut-off structure solenoid valve to solve the problems raised in the background technology.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] 14. The invention relates to a four-position five-way cut-off structure solenoid valve, comprising an electromagnetic connector, a solenoid valve body and a piston assembly. The electromagnetic connector is mounted on the upper end of the solenoid valve body, and the piston assembly can be movably mounted up and down inside the solenoid valve body. The electromagnetic connector comprises a first one-way exhaust joint, a coil assembly and a pilot assembly. The first one-way exhaust joint is mounted on the upper end of the coil assembly, and the pilot assembly is mounted on the lower end. The solenoid valve body is provided with an air inlet, a first exhaust port, a groove body for accommodating the piston assembly, and a second exhaust port. The air inlet and the first exhaust port are located on the side of the solenoid valve body, and the first exhaust port is located above the air inlet. The groove body is arranged inside the solenoid valve body, and the second exhaust port is correspondingly connected to the piston assembly. The piston assembly comprises a piston, a piston rod, a piston sleeve, a piston seat, a spring and a bottom cover. The piston, piston sleeve, piston seat, spring and bottom cover are mounted on the piston rod in sequence from top to bottom.

[0006] Furthermore, the coil assembly includes a coil cover, a first coil, and a coil housing. The coil cover covers the coil housing. The coil assembly comprises three first coils, each evenly arranged within the coil housing. The three first coils are hollow and form air passages with the coil cover and coil housing. The coil housing is provided with outlet holes for guiding the wires within the three first coils. The magnetic effect generated by energizing the coil assembly attracts the pilot assembly, thereby controlling the first one-way exhaust connector to vent the solenoid valve body.

[0007] Furthermore, there are three first one-way exhaust connectors, each corresponding to an air passage formed between the hollow interiors of the three first coils and the coil cover and coil housing. Thus, air is ventilated to the solenoid valve body through the air passage to generate air pressure, thereby controlling the piston assembly within the solenoid valve body.

[0008] Furthermore, there are three pilot components, which correspond to the three first coils and are installed in the electromagnetic connector. The pilot component includes a cap body, a second coil and a sleeve. The cap body is installed at the bottom of the sleeve and is connected to the sleeve and the solenoid valve body through threads. The second coil is installed inside the sleeve, and the upper end of the sleeve is installed in the electromagnetic connector through a threaded connection.

[0009] Furthermore, there are three grooves for accommodating the piston assemblies, corresponding to the three pilot assemblies, and the three grooves are connected through the air inlet and the first exhaust port. After the piston assemblies in the three grooves are controlled to move up and down, the air is discharged corresponding to the first exhaust port and the second exhaust port respectively.

[0010] Furthermore, there are three piston assemblies, including a first piston assembly, a second piston assembly, and a third piston assembly, which are correspondingly disposed in the three grooves of the solenoid valve body. Thus, the first piston assembly, the second piston assembly, and the third piston assembly simultaneously control the operation of the three actuators.

[0011] Furthermore, the bottom cover and the piston sleeve of the three piston assemblies are connected to form a closed cavity, the bottom cover is provided with a first through hole, and the piston sleeve is provided with a second through hole, so that air enters the closed cavity through the first through hole and exits through the second through hole.

[0012] Furthermore, there are three second exhaust ports, corresponding to the bottom covers and piston sleeves on the three piston assemblies, which are connected to form a closed cavity. Thus, gas is discharged from the three piston assemblies through the three second exhaust ports, thereby controlling the operation of the three actuators.

[0013] Furthermore, a second one-way exhaust joint is installed on the first exhaust port, thereby ensuring one-way exhaust.

[0014] Furthermore, the solenoid valve body is provided with three manual buttons, which are respectively provided between the three piston assemblies and the three pilot assemblies, so that the piston assemblies that are not in operation can be stopped manually.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The present invention provides a four-position five-way cut-off structure solenoid valve, comprising an electromagnetic connector, an electromagnetic valve body and a piston assembly, wherein the electromagnetic connector comprises a first one-way exhaust joint, a coil assembly and a pilot assembly, the groove body is arranged inside the electromagnetic valve body, and the second exhaust port is correspondingly connected to the piston assembly, and the piston assembly comprises a piston, a piston rod, a piston sleeve, a piston seat, a spring and a bottom cover. This four-position five-way cut-off structure solenoid valve is capable of controlling the operation of multiple actuators by arranging three piston assemblies that can move up and down in the electromagnetic valve body and controlling them separately through three electromagnetic connectors. Each actuator is independent of each other and does not interfere with each other. Moreover, when the original component controlling a certain actuator fails, the entire four-position five-way cut-off structure solenoid valve can continue to operate without affecting the normal operation of other actuators.

There are three first coils 5, each evenly spaced within the coil housing 6. The three first coils 5 are hollow and form air passages with the coil cover 4 and coil housing 6. The coil housing 6 is provided with outlet holes 7 for guiding the wires within the three first coils 5. There are three first one-way exhaust connectors 1-1, each corresponding to the hollow interiors of the three first coils 5 and the air passages formed with the coil cover 4 and coil housing 6. There are three pilot assemblies 1-2, each corresponding to the three first coils 5 and mounted within the electromagnetic connector 1. The pilot assembly 1-2 includes a cap 8, a second coil, and a sleeve 9. The cap 8 is mounted on the bottom of the sleeve 9 and is threadedly connected to the sleeve 9 and the solenoid valve body 2. The second coil is mounted within the sleeve 9, and the upper end of the sleeve 9 is threadedly mounted within the electromagnetic connector 1. There are three grooves 2-3 for accommodating piston assemblies, corresponding to the three pilot assemblies 1-2. The three grooves 2-3 are connected by the air inlet 2-1 and the first exhaust port 2-2. There are three piston assemblies 3, including a first piston assembly 3-7, a second piston assembly 3-8, and a third piston assembly 3-9. The first piston assembly 3-7, the second piston assembly 3-8, and the third piston assembly 3-9 are correspondingly arranged in the three grooves 2-3 of the solenoid valve body 2.The bottom cover 3-6 and piston sleeve 3-3 of the three piston assemblies 3 are connected to form a sealed cavity. The bottom cover 3-6 is provided with a first through hole 10, and the piston sleeve 3-3 is provided with a second through hole 11. There are three second exhaust ports 2-4, each corresponding to the bottom cover 3-6 and piston sleeve 3-3 on the three piston assemblies 3 connected to form a sealed cavity. A second one-way exhaust connector 12 is installed on the first exhaust port 2-2. The solenoid valve body 2 is also provided with three manual buttons 13, each corresponding to the three piston assemblies 3 and the three pilot assemblies 1-2.

[0019] Specific working principle: When the three first coils 5 in the electromagnetic connector 1 are not energized, air enters the electromagnetic valve body 2 from the air inlet 2-1. Since the electromagnetic valve body 2 is provided with three slots 2-3, the three slots 2-3 are connected with the first exhaust port 2-2 through the air inlet 2-1. The first piston assembly 3-7, the second piston assembly 3-8 and the third piston assembly 3-9 are respectively provided in the three slots 2-3. The bottom cover 3-6 and the piston sleeve 3-3 of the three piston assemblies 3 are connected to form a closed cavity. The bottom cover 3-6 is provided with a The first through hole 10 and the second through hole 11 are provided on the piston sleeve. Therefore, as the air pressure increases and cooperates with the action of the spring 3-5, the piston seat 3-4 pushes the piston rod 3-2 and the piston 3-1 to slide upward and seal with the piston sleeve 3-3. At this time, the second through hole 11 on the piston sleeve 3-3 is connected to the first exhaust port 2-2, so that the gas in the control actuator can enter from the air inlet 2-1 and finally be discharged from the second one-way exhaust joint 12 corresponding to the first exhaust port 2-2; when the electric When the three first coils 5 in the magnetic connector 1 are energized, the second coils on the shaft sleeves 9 in the three pilot components 1-2 and the three first coils 5 on the electromagnetic connector 1 are attracted upward due to the magnetic force, so that the three pilot components 1-2 are respectively connected to the three slots 2-3 in the electromagnetic valve body 2. At this time, air enters from the three first one-way exhaust joints 1-1. Since the three first one-way exhaust joints 1-1 are respectively connected to the hollow interiors of the three first coils 5 and the air ducts formed with the coil cover 4 and the coil housing 6, the air passes through the The air passage finally enters the solenoid valve body 2. Similarly, due to the action of air pressure, the piston 3-1 and the piston rod 3-2 on the three piston assemblies 3 are pushed downward, and the piston seat 3-4 slides down and is tightly sealed with the piston sleeve 3-3. At this time, the air inlet 2-1 is connected with the second through hole 11 on the piston sleeve 3-3, and the second through hole 11 is connected with the second exhaust port 2-4. Therefore, the air entering the air inlet 2-1 is finally discharged from the second exhaust port 2-4, thereby controlling the second exhaust port 2-4 to connect to the actuator to make it work.

[0020] In addition, the second one-way exhaust connector 12 provided on the solenoid valve body 2 of this four-position five-way cut-off structure solenoid valve and the first one-way exhaust connector 1-1 provided on the electromagnetic connector 1 are both one-way structure connectors, and air can only be discharged but not entered. In addition, the first coil 5 and the cable outlet of the outlet through hole 7 are both sealed with glue, and the protection level can reach P68, so it can be used in deep water.
