[0002] The shuttle valve on the existing fluid equipment is used for the automatic selection of two oil supply pressure oil passages, and one of the pressure oil supply passages is selected according to the pressure of the two oil supply pressure oil passages acting on both ends of the valve core. When the shuttle valve When the pressure of the oil outlet channel is greater than the pressure of the two oil supply channels, the shuttle valve cannot effectively control the self-locking seal of one of the oil channels; Long core, complex channel structure in the valve body, large volume and low reliability
[0003] There are some deficiencies in the existing shuttle-shaped self-locking control valve scheme. The valve core seat and the valve core belong to the main self-locking sealing structure in the work, and the valve core seat is easily impacted and damaged during the frequent opening and closing process. , easy to cause leakage. If the valve core seat cannot be disassembled independently, maintenance is inconvenient. It can only be used for pipeline control in an infrequent switch state. The hardness of the valve core seat needs to be hardened. The structure of the valve core seat is too complicated. The cost of processing is higher

The invention relates to fluid systems, in particular to a fusiform self-locking fluidic control device capable of controlling the fluid motion. The fusiform self-locking fluidic control device comprises a valve body mechanism and a valve element; and the valve body mechanism comprises a channel and a valve element seat. The fusiform self-locking fluidic control device is characterized in that the valve body mechanism comprises a valve element sealing seat, and the valve element sealing seat is provided with a sealing seat channel; a valve element cavity composed of the valve element sealing seat, the valve core seat and the channel is included, and is communicated with the sealing seat channel; the valve element seat is provided with a fluid channel, and the valve element is assembled at the position, between the valve element sealing seat and the valve element seat, in the valve element cavity; and a low-pressure jet flow channel and a jet flow switch which is assembled on the low-pressure jet flow channel are included. According to the scheme, jet flow in the low-pressure jet flow channel is adopted to control the motion of the valve element and the fluid flowing direction, and the fusiform self-locking fluidic control device has the novelty, creativeness and use value.
Description
technical field [0001] The invention relates to a shuttle-shaped self-locking jet control device for controlling fluid movement in a fluid system. Background technique [0002] The shuttle valve on the existing fluid equipment is used for the automatic selection of two oil supply pressure oil passages, and one of the pressure oil supply passages is selected according to the pressure of the two oil supply pressure oil passages acting on both ends of the valve core. When the shuttle valve When the pressure of the oil outlet channel is greater than the pressure of the two oil supply channels, the shuttle valve cannot effectively control the self-locking seal of one of the oil channels; The core is long, the channel structure in the valve body is complex, the volume is large, and the reliability is low. [0003] There are some deficiencies in the existing shuttle-shaped self-locking control valve scheme. The valve core seat and the valve core belong to the main self-locking sea...
