Description

Technical Field

[0001] The utility model relates to the technical field of multi - joint valves, and particularly relates to a multi - joint valve group substrate structure. Background Art

[0002] In the field of automatic fluid control, as a key component in the fluid distribution and control system, the design and performance of the valve group substrate directly affect the efficiency, stability, and maintainability of the entire system. The traditional valve group substrate structure often has problems such as low space utilization rate, complex fluid flow paths, inconvenient installation and maintenance of control valves, etc., and it is difficult to meet the requirements of modern industry for efficient, flexible, and reliable fluid control. Specifically, the traditional valve group substrate usually adopts a single - straight - line plus shunt layout, with complex fluid paths and difficult to adjust flexibly, resulting in easy generation of pressure drop and eddy current during fluid transmission, affecting system performance; the thickness and weight of the valve group substrate are also often large, increasing the difficulty of installation and maintenance. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a multi - joint valve group substrate structure for optimizing the fluid path of the valve group substrate and improving space utilization rate.

[0004] The utility model adopts the following technical scheme: A multi - joint valve group substrate structure, comprising:

[0005] A main channel is opened on the substrate, and the two ends of the main channel are respectively a liquid inlet and a liquid return port;

[0006] Multiple liquid outlet holes are opened on the substrate;

[0007] Pairs of valve inlet holes and valve outlet holes are opened on the substrate;

[0008] Among them, each pair of the valve inlet holes and valve outlet holes is relatively matched with a liquid outlet hole and a control valve; the valve inlet holes are communicated to the main channel, the valve outlet holes are communicated to the corresponding liquid outlet holes, and the valve inlet holes and valve outlet holes are connected to the liquid inlet end and the liquid outlet end of the corresponding control valve.

[0009] Furthermore, the valve inlet holes and valve outlet holes are opened on the upper and lower side surfaces of the substrate, and the liquid outlet holes are opened on the front and rear side surfaces of the substrate.

[0010] The main channel includes a plurality of first straight channels opened in the substrate, and the valve inlet holes on the upper and lower side surfaces of the substrate are sequentially communicated through the first straight channels; the liquid inlet and liquid return ports are also respectively communicated to the nearest valve inlet holes through a first straight channel.

[0011] A third straight channel is opened at the center of the inner end of the liquid outlet hole, and the third straight channel is communicated to the valve outlet hole through a second straight channel opened in the substrate.

[0012] Multiple of the liquid outlet holes are grouped, and the liquid outlet holes grouped on the front and rear sides of the substrate are arranged staggeredly; the main channel is in an S shape in the projection on the lower side of the substrate and is staggered with the grouped liquid outlet holes.

[0013] Threaded holes for installing control valves are provided on the upper and lower sides of the substrate.

[0014] Internal threads are provided on the inner wall of the liquid outlet hole, and a connector is connected to the liquid outlet hole by threading.

[0015] The connector includes a tube body installed in the liquid outlet hole. One end of the tube body close to the bottom surface of the liquid outlet hole has a frustum, and the tube body and the frustum are integrally formed; a groove is provided on the inner end surface of the frustum, and a sealing ring is installed in the groove of the frustum, and the sealing ring is squeezed between the inner end surface of the frustum and the bottom surface of the liquid outlet hole.

[0016] A washer and a compression sleeve are sleeved on the tube body. The compression sleeve is connected to the liquid outlet hole by threading, and the washer is squeezed between the frustum and the compression sleeve; a hexagonal head is provided at the outer end of the compression sleeve.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The main channel adopts a form of being bent and connected by multiple first straight channels, so that the fluid can flow smoothly through each control valve. Cooperating with multiple groups of liquid outlet holes, the fluid can be distributed to different paths according to needs, enhancing the flexibility and control ability of the system;

[0019] The substrate adopts a cuboid design. By providing valve inlet holes and valve outlet holes on the upper and lower sides, and the opposite design of the valve hole layout in the middle and at both ends, the projection of the main channel on the lower side of the substrate is in an S shape. This not only reduces the thickness of the substrate in the front and rear directions, but also optimizes the space layout and improves the space utilization rate.

[0020] Each control valve is fixed on the upper and lower sides of the substrate through threaded holes, making the replacement and maintenance of the control valve simple and fast; the substrate design has a modular feature. By increasing or decreasing the number and position of the control valves, it can flexibly adapt to different fluid control requirements; it not only reduces the manufacturing cost, but also improves the scalability and adaptability of the system.

[0034] Taking Figure 1 , Figure 2As shown in the orientation description, liquid inlet ports 15 and liquid return ports 16 are respectively opened at the left and right ends of the substrate 1. The main channel 11 is opened in the substrate 1 and communicates with the liquid inlet port 15 and the liquid return port 16 at both ends. A set of liquid outlet holes 12 are respectively opened at both ends of the rear side of the substrate 1. Each set of liquid outlet holes 12 has ten and is arranged in two upper and lower rows. A set of liquid outlet holes 12 are opened in the middle of the front side of the substrate 1. This set of liquid outlet holes 12 has eight and is arranged in two upper and lower rows. Valve inlet holes 13 and valve outlet holes 14 are arranged in pairs on the upper and lower sides of the substrate 1. Each pair of valve inlet holes 13 and valve outlet holes 14 cooperate with a liquid outlet hole 12 and a control valve. Threaded holes 17 for installing control valves are opened on the upper and lower sides of the substrate 1. The control valves are fixed on the upper and lower sides of the substrate 1 through the threaded holes 17. After installation, the liquid inlet end and the liquid outlet end of the control valve are respectively corresponding and communicating with the valve inlet hole 13 and the valve outlet hole 14.

[0035] A third straight channel 122 is opened at the center of the inner end of the liquid outlet hole 12.

The valve inlet holes 13 on the upper and lower sides of the substrate 1 are sequentially communicated through a plurality of first straight channels 111 opened in the substrate 1. The liquid inlet port 15 and the liquid return port 16 also communicate with the nearest valve inlet hole 13 through a first straight channel 111 respectively.

[0039] The joint 2 includes a pipe body 21 and a frustum 22 fixed to the inner end of the pipe body 21, and the pipe body 21 and the frustum 22 are integrally formed. Two circles of grooves are formed on the inner end face of the frustum 22, and a sealing ring 23 is installed in the grooves of the frustum 22. After the joint 2 is installed, the inner end of the pipe body 21 is aligned with the third straight channel 122, and the sealing ring 23 is squeezed between the inner end face of the frustum 22 and the bottom surface of the liquid outlet hole 12, realizing the sealed connection between the joint 2 and the liquid outlet hole 12. The compression sleeve 25 and the washer 24 are sleeved on the pipe body 21, the compression sleeve 25 is threadedly connected in the liquid outlet hole 12, and the washer 24 is squeezed between the frustum 22 and the compression sleeve 25. The outer end of the compression sleeve 25 is substantially flush with the surface of the substrate 1, and a hexagonal head 251 is provided at the outer end of the compression sleeve 25, which is convenient for screwing the compression sleeve 25 tightly in the liquid outlet hole 12.
