Abstract

The invention provides a buoyancy valve. The buoyancy valve comprises a valve body, wherein a valve cavity and a buoyancy cavity are arranged inside the valve body; a valve core is arranged inside the valve cavity; a floater is arranged inside the buoyancy cavity, and is connected with a core shaft of the valve core; a first port, a second port, a third port and a fourth port are arranged on the valve body; the first port and the second port are communicated with the valve cavity; the third port and the fourth port are communicated with the buoyancy cavity; the floater has an original state and a floating state; when the floater is at the original state, the buoyancy valve switches off the first port and the second port; when the floater is located at the floating state, the buoyancy valve is communicated with the first port and the second port. The buoyancy valve can be used for identifying when the emptying operation is completed, so that the emptying effect can be effectively ensured, and the service life and the user experience of a washing system can be improved. Furthermore, the invention further provides the washing system with the buoyancy valve and an engineering machine.

Description

technical field [0001] The invention relates to construction machinery, in particular to a buoyancy valve; in addition, it also relates to a water washing system and construction machinery with the buoyancy valve. Background technique [0002] At present, construction machinery has been widely used in various construction operations, which has brought great convenience to construction. Many construction machinery (such as concrete pumping equipment, mixer trucks, etc.) often need to be partially cleaned after the operation is completed. For this reason, these construction machinery are usually provided with a water washing system. [0003] In order to prevent the adverse effects of accumulated water on the water washing system, such as causing rust or freezing in a cold environment and then freezing the water pump, it is usually necessary to empty the water after the completion of the water washing operation. The existing emptying method is mainly manual air pressure emptyi...
