Abstract

The invention relates to the technical field of design and manufacture of valves, and in particular relates to a double-acting gas-controlled switch. The double-acting gas-controlled switch comprises a valve body and a driving base, wherein a piston group, a guide wheel group and a driving rod group are arranged in the driving base; the piston is arranged in an X direction relative to the driving base; the guide wheel group is arranged in a Z direction relative to the driving base; the driving rod group is arranged in a Y direction relative to the driving base; a plurality of tooth sockets are arranged on the piston group; racks meshed with the tooth sockets are arranged at the tail end of the guide wheel group; an eccentric shaft which resists against the tail end of the driving rod group is arranged at the head end of the guide wheel group; the head end of the driving rod group is connected with a valve core; the guide wheel group is driven by the piston group to do rotary motion along the X direction; the driving rod group is controlled by the guide wheel group by virtue of the eccentric shaft to do Y-directional feed motion; the driving rod group is used for controlling the opening or closing of the valve body by virtue of a valve core. According to the double-acting gas-controlled switch, the opening or closing of the valve body is realized by using a lead screw driving principle, so that the effect of accurate control is realized; meanwhile, the supply of the power is realized by utilizing the principle of a piston, and a hardware condition is created for manual control and automation pneumatic control.

Description

technical field [0001] The invention relates to the technical field of valve design and manufacture, in particular to a double-acting air control switch. Background technique [0002] With the advancement of science and technology, people pay more and more attention to industrial safety issues. In the actual safety production process, there are mainly two types of switches commonly used: pneumatic control switches and electric control switches; among them, electric control switches mainly have complicated wiring. , high leakage risk, high maintenance cost and other defects, which make it unfavorable for safe production; most of the existing pneumatic control switches are single-control switches and due to unreasonable structural design, they cannot be used in applications with high safety requirements. place. [0003] Therefore, it is necessary to propose an improvement scheme to the existing pneumatic switch to improve its safety performance and ensure the personal safety ...
