Technical Field

[0001] This utility model relates to the field of flow valve island technology, and in particular to a novel flow valve island. Background Technology

[0002] A flow valve island is an integrated and modular fluid control unit, mainly used for the precise adjustment, distribution and centralized control of the flow of multiple fluid media in automated systems. It is widely used in industrial automated production lines, hydraulic / pneumatic systems, fluid conveying equipment and intelligent manufacturing equipment.

[0003] Chinese Patent Publication No. CN209372334U, published on 20190910, discloses a non-bridge-type flow valve island. The non-bridge-type flow valve island includes a valve seat and a valve island body mounted on the valve seat. The valve island body includes a first solenoid valve, a second solenoid valve, a pressure sensor, and a flow sensor. The valve seat has a first gas channel, a second gas channel, an inlet, and an outlet. The first solenoid valve connects the inlet to the inlet end of the first gas channel. The second solenoid valve connects the outlet end of the first gas channel to the inlet end of the second gas channel. The flow sensor connects the outlet to the outlet end of the second gas channel. The pressure sensor is disposed on the first gas channel and is used to test the gas pressure in the first gas channel.

[0004] The existing flow valve island connects the solenoid valve, flow switch, and pressure sensor with a connector and air pipe. The solenoid valve controls the air supply, the flow switch accurately detects the flow rate, and the pressure sensor measures the pipeline pressure. The existing air pipe connection between the flow meter and the pressure sensor poses a risk of air leakage. If the air pipe and connector are not properly assembled, air leakage will occur. At the same time, the large space required for assembly prevents the reduction of the instrument size. The air pipe connection between the various parts occupies a large space. Therefore, there is an urgent need to propose a new type of flow valve island to solve the above problems. Utility Model Content

A pressure sensor is fixedly connected to the top of the secondary valve seat. A Y valve is fixedly connected to the side of the main valve seat near the stop screw. A pilot air inlet and a test air source inlet are respectively connected to the horizontal sides of the Y valve.

[0007] Preferably, the fixing component includes a plug screw, the main valve seat and the auxiliary valve seat are fixedly connected by the plug screw, and the flow switch is snapped between the main valve seat and the auxiliary valve seat.

[0008] Preferably, the set screws are provided in multiple sets, and the multiple sets of set screws are arranged in a rectangular pattern.

[0009] Preferably, a sealing silicone sealant is provided between the pressure sensor and the secondary valve seat.

[0010] Preferably, the main valve seat is fixedly connected to the Y valve by multiple sets of fixing screws.

A Y-valve controls the on / off state of the gas path. The Y-valve is fixed to the main valve seat with fixing screws and sealed with two O-rings. The gas from the Y-valve reaches the main valve seat and then enters the flow switch. O-rings are inserted into both ends of the flow switch and clamped between the main valve seat and the auxiliary valve seat. The main valve seat and the auxiliary valve seat are fixed with plug screws. Gas enters the auxiliary valve seat, and a pressure sensor is fixed to the auxiliary valve seat with screws and sealed with silicone sealant. The pressure at the auxiliary valve seat is detected.
