Embodiment
[0016] Such as figure 2 As shown, it is an integrated reversing valve applied to water source heat pump. The valve body and the auxiliary valve chamber are formed by the plunger rod and the compartment ring to form two independent plunger chambers. There is a plunger in the plunger chamber. The plunger is connected by a plunger rod, and one end of the plunger rod extends out of the valve body. It is sealed by a sealing device and connected with the driver device. The two ends and the middle of the plunger chamber in the auxiliary valve chamber are respectively provided with main passages. The connection or disconnection between the main passages is controlled by the movement of the plunger. There is a main channel in the middle of the plug cavity, and the connection or break between the main channels is controlled by the movement of the plunger. The secondary channel, the on or off of the secondary channel is controlled by the movement of the plunger, the driving device 4 ca...

The invention relates to control valve technologies, in particular to an integrated reversing valve. The integrated reversing valve is provided with a valve body and is characterized in that at least two longitudinal valve cavities are arranged in the valve body, at least two independent plunger cavities are formed by each valve cavity through a plunger rod and a partition ring, a plunger is arranged in each plunger cavity, the plungers in each valve cavity are connected through the corresponding plunger rod, through holes in the plunger cavities and the end faces of the valve body are main channels, channels connected between the plunger cavities are auxiliary channels, and one end of each plunger rod stretches out of the valve body, sealed through a seal device and connected with a driving device. The valve cavities and multiple valve rods are arranged in the valve body, the reversing valve is integrated, and the integrated reversing valve has multiple functions and has the advantages of being compact in structure, complete in function, convenient to operate and the like.
Description
technical field [0001] The invention relates to control valve technology, in particular to an integrated reversing valve with compact structure, which is especially suitable for controlling the flow direction and flow rate of liquid. Background technique [0002] We know that the reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cut-off and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. There are many types of reversing valves, such as according to the structure of the valve: slide valve type, rotary valve type, ball valve type, cone valve type; such as according to the control mode of the valve: manual type, motorized type, electromagnetic type, hydraulic type, Electro-hydraulic type, pneumatic type; according to the number of working positions of the valve and the number of channels controlled: 2-position 2-way valve, 2-posi...
