[0025] like Figure 1-6 As shown, this utility model provides a quick-install valve seat, including a seat body 1, a fixing hole, a vent hole, and an exhaust hole disposed on the seat body 1. The fixing hole includes a mounting through hole 4 penetrating the upper and lower end faces of the seat body 1, and a mounting blind hole 5 disposed on the upper end face of the seat body 1. The exhaust hole includes a first exhaust blind hole 6 disposed on the front end face of the seat body 1 and a second exhaust blind hole 7 disposed on the rear end face of the seat body 1. The vent hole includes a first vent hole 8 and a second vent hole 9 disposed on the lower end face of the seat body 1, a first vent blind hole 10, a second vent blind hole 11, and a third vent blind hole 12 disposed on the upper end face of the seat body 1, and a filter pressure reducing vent blind hole 13 disposed on the front end face of the seat body 1.

[0026] The second air passage blind hole 11, the upper end of the first air passage hole 8, the third air passage blind hole 12, the upper end of the second air passage hole 9, and the first air passage blind hole 10 are arranged sequentially from left to right on the upper end face of the base body 1. The first air passage hole 8 and the second air passage hole 9 both penetrate the upper and lower end faces of the base body 1. The filter pressure reducing air passage blind hole 13 is connected to the third air passage blind hole 12. The first air passage blind hole 10 is connected to the first exhaust blind hole 6. The second air passage blind hole 11 is connected to the second exhaust blind hole 7.

[0027] Mounting through hole 4 is used to install pneumatic actuators. It is suitable for pneumatic actuators that conform to the NAMUR installation standard. The two air inlet ends of the pneumatic actuator are attached to the lower end of the base 1 and correspond to the first air passage hole 8 and the second air passage hole 9, respectively. The pneumatic actuator is fixed by bolts passing through mounting through hole 4 from the upper end face of the base 1 and fixing it to the mounting hole of the pneumatic actuator. The mounting hole of the pneumatic actuator is generally threaded. If not, a nut is required for fixing.

[0028] The filter pressure reducing valve is installed on the front end face of the seat 1. The air outlet of the filter pressure reducing valve corresponds to the filter pressure reducing blind hole 13. The airflow enters through the inlet of the filter pressure reducing valve, is filtered and pressure regulated, and then enters the filter pressure reducing blind hole 13 through the outlet, and then enters the solenoid valve through the third blind hole 12. The filter pressure reducing valve can be fixed by snap-fit ​​or bolt, which is not limited here.

[0029] One end of the first vent hole 8 and the second vent hole 9, the first vent blind hole 10, the second vent blind hole 11 and the third vent blind hole 12 are all located on the upper end face of the seat body 1, corresponding to the holes on the solenoid valve.

[0030] The other end of the first air passage hole 8 and the second air passage hole 9 are located on the lower end face of the base 1. They are used for air exchange between the solenoid valve and the pneumatic actuator. The solenoid valve controls the air intake of the pneumatic actuator, and the airflow enters the pneumatic actuator from the output end of the solenoid valve through the first air passage hole 8 or the second air passage hole 9.

[0031] The first vent blind hole 10 and the second vent blind hole 11 are respectively connected to the first exhaust blind hole 6 and the second exhaust blind hole 7. When the solenoid valve controls the exhaust, the airflow enters the first vent blind hole 10 or the second vent blind hole 11 from the exhaust end of the solenoid valve, and is discharged through the first exhaust blind hole 6 or the second exhaust blind hole 7.

[0032] Both the first exhaust blind hole 6 and the filter pressure reducing blind hole 13 are located on the front end face of the base body 1. The first exhaust blind hole 6 is located below the filter pressure reducing blind hole 13, ensuring that the first exhaust blind hole 6 will not be blocked after the filter pressure reducing valve is installed on the front end face of the base body 1.

[0033] like Figure 1-3 As shown, it also includes a mounting groove 2 disposed on the upper end face of the base 1. The second air passage blind hole 11, the upper end of the first air passage hole 8, the third air passage blind hole 12, the upper end of the second air passage hole 9, and the first air passage blind hole 10 are all located in the mounting groove 2.

[0034] Mounting slot 2 is used to install solenoid valves and is suitable for SY series solenoid valves. During assembly, the solenoid valve is embedded into mounting slot 2 and then tightened with bolts. Mounting blind hole 5 has internal threads. The position of mounting blind hole 5 corresponds to the position of mounting hole of solenoid valve. After passing the bolt through the mounting hole on the solenoid valve into mounting blind hole 5, tighten it. The disassembly and assembly are fast and the operation is simple and convenient.

[0035] like Figure 1-2 As shown, it also includes a mounting rail 3 disposed on the front end face of the base 1, and the filter pressure reducing blind hole 13 is disposed on the mounting rail 3.

[0036] Mounting rail 3 is used to install the filter pressure reducing valve, mainly applicable to the SMC brand AW20 series filter pressure reducing valve. The filter pressure reducing valve has a sliding groove structure on its side that matches the mounting rail 3. The filter pressure reducing valve can slide and engage with the mounting rail 3 through the sliding groove, making assembly more convenient. Depending on the actual situation, other methods of fastening can be selected.

[0037] like Figure 2-3 As shown, it also includes a fourth vent blind hole 14 and a fifth vent blind hole 15 disposed on the lower end face of the base 1. The fourth vent blind hole 14 is connected to the first vent hole 8, and the fifth vent blind hole 15 is connected to the second vent hole 9.

[0038] The first air passage hole 8, the second air passage hole 9, the fourth air passage blind hole 14, and the fifth air passage blind hole 15 are arranged in a cross shape on the lower end face of the base 1. When the pneumatic actuator is installed on the automated equipment, some are installed horizontally and some are installed vertically. The pneumatic actuator has two air inlets, which need to be aligned with the first air passage hole 8 and the second air passage hole 9, or with the fourth air passage blind hole 14 and the fifth air passage blind hole 15 during installation. Depending on the actual situation, the installation orientation of the base 1 can be flexibly adjusted when installing the base 1 on the pneumatic actuator to ensure that the drain port of the filter pressure reducing valve is vertically downward for easy drainage.

[0039] like Figure 2-3 As shown, it also includes a sealing groove 16 disposed on the lower end face of the base 1, and the first air passage hole 8, the second air passage hole 9, the fourth air passage blind hole 14 and the fifth air passage blind hole 15 are all located in the sealing groove 16.

[0040] The sealing groove 16 is used to install the sealing gasket, further sealing the lower end face of the base 1 and the air inlet end of the pneumatic actuator, improving the sealing effect, and the sealing groove 16 makes installation more convenient and simpler.

[0041] like Figure 2 , 5As shown in Figure 6, it also includes a sealing gasket 17 disposed in the sealing groove 16. The sealing gasket 17 includes a gasket body adapted to the shape of the sealing groove 16 and an avoidance through hole 18 disposed on the gasket body and corresponding to the first air passage hole 8 and the second air passage hole 9.

[0042] The sealing gasket 17 is shaped to fit the sealing groove 16, and two gaskets are provided. During installation, the sealing gasket 17 can be placed inside the sealing groove 16, making installation more convenient. There are two clearance holes 18, which correspond to the two air inlets of the pneumatic actuator. When the installation direction of the pneumatic actuator is adjusted, the direction of the sealing gasket 17 is adjusted synchronously, so that the clearance holes 18 on the sealing gasket 17 correspond to the two air inlets of the pneumatic actuator. When the first air passage hole 8 and the second air passage hole 9 on the lower end face of the base 1 correspond to the two air inlets of the pneumatic actuator, the fourth air passage blind hole 14 and the fifth air passage blind hole 15 are closed with the help of the sealing gasket 17. When the fourth air passage blind hole 14 and the fifth air passage blind hole 15 on the lower end face of the base 1 correspond to the two air inlets of the pneumatic actuator, the first air passage hole 8 and the second air passage hole 9 are closed with the help of the sealing gasket 17. The adjustment is convenient and the use is flexible.

[0043] like Figure 1 As shown, the mounting guide rail 3 is provided with two vertical slots 19, and the filter pressure reducing blind hole 13 is provided between the slots 19.

[0044] The filter pressure reducing valve is fitted with a positioning protrusion in the slide groove of the mounting guide rail 3 that corresponds to the locking slot 19. After the filter pressure reducing valve slides into place on the mounting guide rail 3, it can be positioned by means of the locking slot 19, making it more convenient to use.

[0045] like Figure 1 As shown, the mounting rail 3 has a dovetail-shaped cross-section. This prevents the filter pressure reducing valve from falling off the mounting rail 3, resulting in more stable sliding.

[0046] like Figure 1 As shown, the base 1 has a three-dimensional rectangular structure. All six end faces of the base 1 are flat, which facilitates processing, sealing, and assembly.
