A valve device is provided, including a valve body unit and a valve seat. The valve seat is provided with a mounting cavity, and an end of the valve body unit is mounted in the mounting cavity. The valve device further includes a limiting unit, an outer side wall of the valve seat is provided with a mounting hole in communication with the mounting cavity along a radial direction of the mounting cavity, a side wall of the mounting cavity is recessed to form a mounting groove corresponding to the mounting hole, an end of the limiting unit extends into the mounting cavity from the mounting hole and is inserted into the mounting groove, and the limiting unit that extends into the mounting cavity abuts against the valve body unit to perform limiting along an axial direction and a circumferential direction between the valve body unit and the valve seat.

Valve device

A valve device is provided. The valve device includes a valve body unit, a mounting seat and a valve seat. The valve device further includes a fastening member. The mounting seat is provided with a limiting step, and a side surface of the valve seat is provided with a connecting hole in communication with the mounting hole along a direction perpendicular to an axis of the mounting hole. And an end of the fastening member extends into the mounting hole from the connecting hole and abuts against the limiting step.

Connection for valve seat and valve body unit

Disclosed are a combined four-way valve, an air conditioning system, and a vehicle. The combined four-way valve includes a valve seat, a first control valve, a second control valve, a third control valve and a fourth control valve, where the valve seat is internally provided with an input port, an output port, a first opening, a second opening, and a plurality of valve cavities which are arranged at intervals and are arranged corresponding to the control valves on a one-to-one correspondence manner; the plurality of valve cavities include a first valve cavity, a second valve cavity, a third valve cavity and a fourth valve cavity; the valve cavities are in communication with one another by channels; the valve cavities are provided with inlets and outlets, and are in communication with flow channels in the valve seat.

Combined four-way valve, air conditioning system and vehicle

An electromagnetic valve and an electromagnetic valve assembly are provided. The electromagnetic valve includes: a valve body, which at least includes a valve seat, the valve seat being mounted on a mounting base; a magnetic conductive frame, which is fixed to the valve seat; and an electromagnetic driving assembly, which is mounted in the magnetic conductive frame. The magnetic conductive frame is provided with a positioning member, and the positioning member cooperates with the mounting base so as to restrict the electromagnetic driving assembly from rotating relative to the mounting base.
