Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, specifically to an explosion-proof inline five-valve manifold. Background Technology

[0002] The main function of a valve assembly is to control the flow of fluid. A valve assembly consists of a valve and an actuator, which can be an electromagnet or a pneumatic component. By controlling the actuator, the valve can be opened or closed, thereby controlling the flow of fluid. Valve assemblies are often used in simple fluid control applications. Most valve assemblies are single-flow-direction pipelines and cannot supply multiple devices through a single inlet channel, resulting in low working efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an explosion-proof inline five-valve assembly to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a five-valve inline assembly includes a base, a housing, and a valve body assembly. The base has an outlet channel on one side, with five outlet channels arranged horizontally at equal intervals. The top of the base has a snap-fit ​​hole, and a valve port hole is provided inside the snap-fit ​​hole. The valve port hole is connected to the outlet channel. The base has inlet channels at both ends, and the inlet channels are connected to the valve port hole. A valve body assembly is provided outside the valve port hole, and a housing is fitted onto the valve body assembly.

[0005] Specifically, the base serves as a connector for connecting to external pipes. It has five outlet channels that connect to the outlet pipes. The outlet channels are parallel to the horizontal plane, and the snap-fit ​​holes are perpendicular to the horizontal plane, so the axes of the outlet channels and the snap-fit ​​holes intersect. Since the snap-fit ​​holes and valve ports are on the same central axis, the valve ports are connected to the outlet channels. The base has inlet channels at both ends. The axis of the inlet channels is parallel to the horizontal plane and perpendicular to the axis of the outlet channels. The inlet channels are connected to the valve ports. There are two inlet channels for connecting to external inlet pipes. When the inlet channels are not needed, they can be sealed with bolts. The valve body assembly is used to control the opening and closing of the valve ports, thereby controlling the five valve ports. The housing is fitted onto the valve body assembly to protect it.

[0006] A guide block is provided inside the snap-fit ​​hole, and an annular block is provided at the bottom of the snap-fit ​​hole. The annular block is fixedly connected to the inner groove of the snap-fit ​​hole. A hollow cavity is provided in the middle of the shell, and a cylinder is provided in the inner groove of the hollow cavity. A snap-fit ​​block is provided at the bottom of the cylinder, and the snap-fit ​​block is sleeved on the bottom of the cylinder. The top of the snap-fit ​​block is fixedly connected to the bottom of the shell. A valve body assembly is provided inside the cylinder. The valve body assembly includes a slider. A blocking block is provided at the bottom of the slider. An inner groove is provided at the top of the slider. A spring is provided at the bottom of the inner groove. The bottom of the spring is fixedly connected to the bottom of the inner groove. A limiting block is provided at the top hole of the cylinder. A nut is provided at the top of the limiting block.

[0007] Specifically, the snap-fit ​​hole is used to connect with the housing. A guide block, which is annular, is provided at the opening of the snap-fit ​​hole. The snap-fit ​​hole is fixedly connected to the guide block. The housing is made of explosion-proof material, specifically stainless steel and cast iron. A hollow cavity is formed in the middle of the housing, and a cylindrical body is located within this cavity and fixedly connected to the inner groove of the cavity. The bottom of the cylindrical body is positioned lower than the bottom of the hollow cavity, thus extending beyond the bottom of the hollow cavity. A snap-fit ​​block is provided on the outer side of the bottom of the cylindrical body, which engages with the snap-fit ​​hole. The outer wall of the bottom of the cylindrical body is fixedly connected to the inner groove of the snap-fit ​​block, and the top of the snap-fit ​​block is fixedly connected to the bottom of the housing. The housing and valve body assembly are connected via the snap-fit ​​block. The housing and valve body are connected, and the number of their components is the same as the outlet channel. The slider is a column with the cylinder on the same central axis. The bottom block of the slider matches the valve port. The spring is located inside the inner groove, and the bottom of the spring is fixedly connected to the bottom of the inner groove. A limiting block is provided at the top of the inner groove of the cavity to prevent the slider from falling off. An electromagnetic block is provided at the bottom of the limiting block to control the spring. Now the slider is controlled to achieve valve port control. When the bottom of the slider moves upward, its bottom surface will move away from the valve port opening surface, so that the inlet channel will connect with the valve port. The flow rate of the flowing medium depends on the distance between the bottom surface of the slider and the valve port opening surface.

[0008] The snap-fit ​​hole and the valve port hole are on the same central axis. The bottom hole of the snap-fit ​​hole is connected to the outlet channel, and the top hole of the snap-fit ​​hole is connected to the inlet channel.

[0009] Specifically, the flowing medium enters the base through the inlet channel and flows to the valve port. At this time, it is restricted by the valve body assembly. When the slider in the valve body assembly cooperates with the valve port, the flowing medium is blocked at the top of the valve port. When the slider in the valve body assembly is controlled by the limiting block, the flowing medium will flow through the valve port to the outlet channel, thereby realizing valve port control of the five outlet channels through the valve body assembly.

[0010] There is a space between the top of the slider and the bottom of the limit block, and the top of the spring is higher than the top of the slider.

[0011] Specifically, there is a space between the slider and the limiting block. This space acts on the movement of the slider. Before the top of the slider contacts the bottom of the limiting block, the top of the spring contacts the bottom of the limiting block to form a buffer space.

[0012] The base has a threaded hole at the bottom.

[0013] Specifically, the base has two threaded holes at the bottom, which are used to fix the entire device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the base is provided with five valve body components, and each of the five valve body components is provided with a housing for protection. The housing and the valve body component are connected to the snap-fit ​​hole in the base through a snap-fit ​​block. The valve body component is used to control the opening and closing of the valve port, thereby realizing the control of the five valve ports. The housing is used to protect the valve body component.

[0016] 2. The housing of this utility model is used to protect the valve body assembly. The housing is made of explosion-proof material, which is composed of stainless steel and cast iron. Attached Figure Description

Detailed Implementation

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0025] like Figures 1-6As shown, this utility model provides a technical solution for an explosion-proof inline five-valve manifold. The inline five-valve manifold includes a base 1, a housing 2, and a valve body assembly 3. The base 1 has an outlet channel 11 on one side, with five outlet channels 11 arranged horizontally at equal intervals. The top of the base 1 has a snap-fit ​​hole 12, and a valve port hole 13 is provided inside the snap-fit ​​hole 12. The valve port hole 13 is connected to the outlet channel 11. The base 1 has inlet channels 16 at both ends, which are connected to the valve port holes 13. The valve body assembly 3 is provided outside the valve port holes 13, and the housing 2 is fitted on the valve body assembly 3.

[0026] Specifically, the base 1 serves as a connector for connecting to external pipes. Its outlet channels 11 have five connections to the outlet pipes. The outlet channels 11 are parallel to the horizontal plane, and the snap-fit ​​holes 12 are perpendicular to the horizontal plane, thus the axes of the outlet channels 11 and the snap-fit ​​holes 12 intersect. Since the snap-fit ​​holes 12 and the valve port holes 13 are on the same central axis, the valve port holes 13 are connected to the outlet channels 11. The base 1 has inlet channels 16 at both ends. The axis of the inlet channels 16 is parallel to the horizontal plane and perpendicular to the axis of the outlet channels 11. The inlet channels 16 are connected to the valve port holes 13. There are two inlet channels 16 for connecting to external inlet pipes. When not needed, the inlet channels 16 can be sealed with bolts. The valve body assembly 3 controls the opening and closing of the valve port holes 13, thereby controlling the five valve ports. The housing 2 is fitted onto the valve body assembly 3 to protect it.

[0027] like Figure 5 , Figure 6 As shown, a guide block 14 is provided inside the snap-fit ​​hole 12, and an annular block 15 is provided at the bottom end of the snap-fit ​​hole 12. The annular block 15 is fixedly connected to the inner groove of the snap-fit ​​hole 12. A hollow cavity 21 is provided in the middle of the shell 2. A cylinder 22 is provided in the inner groove of the hollow cavity 21. A snap-fit ​​block 23 is provided outside the bottom end of the cylinder 22. The snap-fit ​​block 23 is sleeved on the bottom end of the cylinder 22. The top end of the snap-fit ​​block 23 is fixedly connected to the bottom end of the shell 2. A valve body assembly 3 is provided inside the cylinder 22. The valve body assembly 3 includes a slider 31. A blocking block 32 is provided at the bottom end of the slider 31. An inner groove 311 is opened at the top end of the slider 31. A spring 33 is provided at the bottom end of the inner groove 311. The bottom end of the spring 33 is fixedly connected to the bottom end of the inner groove 311. A limiting block 34 is provided at the top hole of the cylinder 22. A nut 35 is provided at the top end of the limiting block 34.

[0028] Specifically, the snap-fit ​​hole 12 is used to connect with the housing 2. A guide block 14 is provided at the opening of the snap-fit ​​hole 12. The guide block 14 is annular. The snap-fit ​​hole 12 is fixedly connected to the guide block 14. The housing 2 is made of explosion-proof material, which is composed of stainless steel and cast iron. A hollow cavity 21 is opened in the middle of the housing 2. The cylinder 22 is located in the hollow cavity 21 and is fixedly connected to the inner groove of the hollow cavity 21. The bottom end of the cylinder 22 is lower than the bottom end of the hollow cavity 21, so that the bottom end of the cylinder 22 extends out of the bottom end of the hollow cavity 21. A snap-fit ​​block 23 is provided on the outer side of the bottom end of the cylinder 22. The snap-fit ​​block 23 is used to snap into the snap-fit ​​hole 12. The outer wall of the bottom end of the cylinder 22 is fixedly connected to the inner groove of the snap-fit ​​block 23. The top end of the snap-fit ​​block 23 is fixedly connected to the bottom end of the housing 2. The housing 2 and the valve body assembly 3 are connected through the snap-fit ​​block 23. The base 1 is connected, and the number of its housing 2 and valve body assembly 3 is the same as that of the outlet channel 11. The slider 31 is a column and is on the same central axis as the cylinder 22. The bottom block 32 of the slider 31 cooperates with the valve port 13. The spring 33 is located inside the inner groove 311, and the bottom end of the spring 33 is fixedly connected to the bottom end of the inner groove 311. The top of the inner groove of the cavity 21 is provided with a limiting block, which is used to prevent the slider 31 from falling off. The bottom end of the limiting block is provided with an electromagnetic block, which is used to control the spring 33. Now the slider 31 is controlled to achieve valve port control. When the bottom end of the slider 31 moves upward, the bottom end face of the slider 31 will move away from the opening face of the valve port 13, so that the inlet channel 16 will be connected to the valve port 13. The flow rate of the flowing medium depends on the distance between the bottom end face of the slider 31 and the opening face of the valve port 13.

[0029] like Figure 5 , Figure 6 As shown, the snap-fit ​​hole 12 and the valve port hole 13 are on the same central axis. The bottom hole of the snap-fit ​​hole 12 is connected to the outlet channel 11, and the top hole of the snap-fit ​​hole 12 is connected to the inlet channel 16.

[0030] Specifically, the flowing medium enters the base 1 through the inlet channel 16 and flows to the valve port 13. At this time, it is restricted by the valve body assembly 3. When the slider 31 in the valve body assembly 3 cooperates with the valve port 13, the flowing medium will be blocked at the top of the valve port 13. When the slider 31 in the valve body assembly 3 is controlled by the limiting block, the flowing medium will flow through the valve port 13 to the outlet channel 11, thereby realizing the valve port control of the five outlet channels 11 through the valve body assembly 3.

[0031] like Figure 5 , Figure 6 As shown, there is a space between the top of the slider 31 and the bottom of the limiting block 34, and the top of the spring 33 is higher than the top of the slider 31.

[0032] Specifically, there is a space between the slider 31 and the limiting block 34. This space acts on the movement of the slider 31. Before the top of the slider 31 contacts the bottom of the limiting block 34, the top of the spring 33 contacts the bottom of the limiting block to form a buffer space.

[0033] like Figure 4 As shown, a threaded hole 17 is provided at the bottom end of the base 1.

[0034] Specifically, the base 1 has two threaded holes 17 at its bottom end. The threaded holes 17 are used to fix the whole device so that the device can be installed in the required position as needed.

[0035] Working principle: This utility model installs the housing 2 and valve body assembly 3 on the base 1, and then connects the inlet pipe to the inlet channel 16. Another inlet channel 16 is sealed by bolts. The flowing medium enters the pipe through the inlet channel 16, and then flows to the valve port 13, where it is confined by the slider 31. An external power supply is connected to the connection end 4 to control the magnetic block in the limiting block to generate magnetic force, which controls the spring 33. The spring 33 drives the slider 31 to move, thereby controlling the valve port 13. Then, the flowing medium flows directly through the valve port 13 to the corresponding outlet channel 11, which is also connected to the external pipe, realizing one inlet and five outlets.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
