[0030] like Figure 1-4 The image shows an embodiment provided by this utility model.

[0031] This utility model embodiment provides a parallel valve assembly, including: an integrally formed valve body 10. The valve body 10 can be designed as a valve body suitable for a three-in-one or five-in-one solenoid valve assembly according to the usage requirements. The valve body 10 is generally cubic in shape. Depending on the manufacturing material of the valve body 10, such as aluminum alloy or engineering plastic, the valve body 10 can be made by integral die casting or extrusion molding process.

[0032] Specifically, the valve body 10 has several independent valve chambers 20. These chambers are connected in parallel via internal channels within the valve body 10 and do not affect each other. Each valve chamber 20 corresponds to one solenoid valve in a parallel valve assembly. If there are three valve chambers 20, the solenoid valve assembly is a three-in-one assembly; if there are five valve chambers 20, the parallel valve assembly is a five-in-one assembly. The number of solenoid valves in the parallel valve assembly can be set according to actual needs. Each solenoid valve can operate independently. The valve chamber 20 is cylindrical, with one end open and the other closed. One end of the valve body 10 is provided with an inlet hole 11 for inleting gas or liquid, and a first outlet hole 12 and a second outlet hole 13 for discharging gas or liquid. The first outlet hole 12 and... The second drain hole 13 is symmetrically arranged on both sides of the inlet hole 11. The top of the valve body 10 is provided with several sets of corresponding first outlet holes 14 and second outlet holes 15. The first outlet holes 14 and second outlet holes 15 are used to connect with the actuator (not shown in the figure). The actuator is a cylinder or a hydraulic cylinder. Each actuator corresponds to a set of first outlet holes 14 and second outlet holes 15. For example, three cylinders are connected to three first outlet holes 14 and three second outlet holes 15, and five hydraulic cylinders are connected to five first outlet holes 14 and five second outlet holes 15. In the state where the valve stem 21 is not installed, each valve chamber 20 is connected to the inlet hole 11, the first drain hole 12, the second drain hole 13, the first outlet hole 14, and the second outlet hole 15.

[0033] With valve stem 21 installed, each valve chamber 20 is equipped with a valve stem 21 (not all are shown in the attached figures). Each valve stem 21 can be independently controlled, and all valve stems 21 can move individually or synchronously. Specifically, the valve stem 21 can be a sliding valve core. A return spring 22 is provided in the valve chamber 20, and the inner end of the valve stem 21 abuts against the return spring 22. The inner wall of the valve chamber 20 is provided with a sealing structure (not shown in the attached figures) for cooperating with the valve stem 21 to switch between sealing different flow channels. The sealing structure can be selected and adapted from commonly used seals according to the type of fluid and the type of valve stem 21. The material of the sealing structure can be selected from silicone rubber, nitrile rubber, fluororubber, polytetrafluoroethylene, etc. In practical use, one or more valve stems 21 can be controlled individually or all valve stems 21 can be controlled simultaneously as needed. When the valve stem 21 moves to the inner end of the valve cavity 20, the inlet hole 11 is connected to the second outlet hole 15, the second outlet hole 15 is connected to the actuator, the actuator is connected to the first outlet hole 14, and the first outlet hole 14 is connected to the first drain hole 12, thereby driving the actuator to perform an action. When the valve stem 21 moves to the outer end of the valve cavity 20, the inlet hole 11 is connected to the first outlet hole 14, the first outlet hole 14 is connected to the actuator, the actuator is connected to the second outlet hole 15, and the second outlet hole 15 is connected to the second drain hole 13, thereby driving the actuator to perform another action.

[0034] After adopting the above-mentioned parallel valve group, the valve bodies 10 of multiple solenoid valves are integrated into one through the integrally formed valve body 10. Then, according to the design requirements, several valve chambers 20 are set on the valve body 10 and connected to the inlet hole 11, the first outlet hole 12, the second outlet hole 13, the first outlet 14, and the second outlet 15 respectively. Then, by using the valve stem 21 set separately in each valve chamber 20, different flow paths can be switched or opened, and different solenoid valves can be controlled to work. The entire parallel valve group has a simple structure and high integrity, which can reduce the processing, manufacturing and assembly costs.

[0035] Specifically, the inlet hole 11 is connected to the inlet channel 101, the first outlet hole 12 and the second outlet hole 13 are respectively connected to the outlet channel 102, the first outlet 14 and the second outlet 15 are respectively connected to the outlet channel 103. The inlet channel 101 and the outlet channel 102 are arranged in the lower middle part of the valve body 10 along the X-axis direction, the valve cavity 20 is arranged in the middle part of the valve body 10 along the Y-axis direction, and the outlet channel 103 is arranged in the upper middle part of the valve body 10 along the Z-axis direction. The distribution of the inlet channel 101, the outlet channel 102, the valve cavity 20 and the outlet channel 103 is compact and reasonable, which can effectively save the installation space and make it easy to control the volume of the entire valve body 10.

[0036] Furthermore, the valve body 10 is provided with several heat dissipation channels 104. The heat dissipation channels 104 are independently provided with the inlet channel 101, the outlet channel 102 and the outlet channel 103. When assisting the valve body 10 in heat dissipation, they do not affect the sealing performance and working status of other channels.

[0037] Specifically, the valve body 10 is made of one of the following materials: copper, stainless steel, cast iron, plastic or aluminum alloy, and the valve stem 21 is made of one of the following materials: stainless steel, copper alloy, aluminum alloy, engineering plastic or ceramic. In specific implementation, the materials of the valve body 10 and valve stem 21 can be selected and matched according to the purpose and application scenario of the parallel valve group.

[0038] Specifically, a number of pilot head assemblies 30 are installed on the valve body 10. A coil assembly 40 is sleeved on the pilot head assembly 30. The coil assembly 40 is inductively connected to the pilot head assembly 30. The pilot head assembly 30 is drively connected to the outer end of the valve stem 21. The pilot head assembly 30 and the coil assembly 40 can be purchased directly on the market. Taking a parallel valve assembly as an example of a pneumatic control valve assembly, the coil assembly 40 is fitted over the pilot head assembly 30 and is usually fixed by a plastic or metal shell. The pilot head assembly 30 is connected to the valve body 10 of the parallel valve assembly by means of threads or bayonet. When the coil assembly 40 is energized, it generates a magnetic field that attracts the iron core inside the pilot head assembly 30. The iron core inside the pilot head assembly 30 moves under the action of electromagnetic force, thereby opening the pilot hole and changing the pressure balance in the valve chamber 20. The pressure difference is used to push the valve stem 21 to move towards the inner end of the valve chamber 20, thereby switching the pneumatic path. When the power is off, the iron core is reset under the action of the spring force, closing the pilot hole. The valve core returns to the initial position under the action of the return spring 22 or the medium pressure, and the pneumatic path also returns to the initial state.

The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
