Abstract

A manual and electric double-control warm water valve comprises an electromagnet, a valve part and a manual control part. The electromagnet comprises a coil, a fixed iron core, a spring and a movableiron core, the valve part comprises a valve seat, an upper sleeve, an upper valve element, a lower sleeve and a lower valve element, and the manual control part comprises a valve rod, a valve rod seatand a hand wheel. The electromagnet is arranged above the valve part, and the manual control part is arranged below the valve part. The upper sleeve and the lower sleeve are arranged in the valve seat, the upper valve element is movably arranged in the upper sleeve, and the lower valve element is movably arranged in the lower sleeve. The fixed iron core, the spring and the movable iron core are sleeved with a coil, the upper end of the fixed iron core is fixedly connected with the coil, the valve rod seat is arranged below the valve seat, the valve rod penetrates through the valve rod seat and the lower valve element and is fixedly connected with the lower valve element, the valve rod is in threaded connection with the valve rod seat, and the lower end of the valve rod is fixedly connected with the hand wheel. The manual and electric double-control warm water valve solves the problem about how to heat for an air conditioner in cold weather when an electric warm water valve breaks down.

Description

technical field

[0001] The invention belongs to the technical field of valves, and in particular relates to a manual electric double-control warm water valve. Background technique

[0002] The heating of the vehicle air conditioner generally uses the cooling water of the engine as the medium. The cooling water takes away the heat of the engine, and part of the cooling water enters the air conditioning box in the cab, and releases the heat into the cab through the fan. The on-off control of cooling water is generally performed through the warm water valve. There are two control methods for the warm water valve, one is manual and the other is electric. The manual warm water valve is a general ball valve. The handle drives the ball in the valve seat to rotate to control the on-off of the waterway. The electric warm water valve is an ordinary solenoid valve, which controls the valve core through the electromagnet to realize the on-off of the waterway.
