5results about How to "Stable and reliable work" patented technology

This invention provides a vehicle air supply system and a vehicle pressure reducing valve. The vehicle air supply system adopts a high-pressure dryer and a back-blowing pipeline structure, which can regenerate the dryer by back-blowing and recover high-pressure gas to a low-pressure storage tank, reducing energy consumption. The vehicle pressure reducing valve in the system includes a body, a primary pressure reducing mechanism, and a secondary pressure reducing mechanism. The body is equipped with a vent, a supply channel, and a transmission channel. The secondary pressure reducing mechanism contains a secondary pressure regulating spring, a secondary return spring, a pressure relief groove, and a secondary valve core, which can realize step-by-step pressure reduction and stabilization of gas, and automatically release pressure when overpressure occurs to protect the gas-using components. It has high pressure regulation accuracy and stable and reliable operation. In conjunction with the vehicle air supply system, it can simultaneously meet the gas demand of the high-pressure air spring and the low-pressure gas-using unit. The system has high integration, good drying effect, safety and stability, and significantly improved applicability and service life.

The speed regulating valve with the reversing function comprises a valve body, an oil port P, an oil port A, an oil port B and an oil port T are formed in the valve body, the oil port P is arranged to be an oil inlet, the oil port A and the oil port B are connected with a system execution element, the oil port T is arranged to be an oil return port and is externally connected with an oil tank, and an oil channel is formed in the valve body. A fixed differential pressure reducing valve core and a reversing valve throttling valve core are mounted in the oil duct; when a throttling valve element of the reversing valve is located on the left side or the right side, the magnitude of current of the electromagnetic controller can be adjusted to change the magnitude of electromagnetic force pushing the valve element to move, and therefore the displacement distance of the valve element and the area of a throttling opening are adjusted, and the functions of liquid flow reversing and speed adjusting can be achieved; therefore, it is guaranteed that the speed of an execution element is stable, loop energy loss can be effectively reduced, loop efficiency is improved, hydraulic impact is reduced, and working stability and reliability of a hydraulic system are improved.

The utility model discloses a thermal steam trap of a thermal power plant steam turbine, and relates to the technical field of steam traps. The steam trap comprises a steam trap and a mounting box, a cylinder is slidably connected in the mounting box, a disc is fixedly arranged at the top of the cylinder and fixedly connected with the steam trap through a screw, communicating pipes are symmetrically and fixedly communicated with the steam trap, first flange plates are slidably connected with the communicating pipes, and a connecting mechanism is arranged between the disc and the first flange plates. A guide pipe is arranged at the end of the communicating pipe, a reinforcing mechanism for reinforcing connection is arranged between the guide pipe and the communicating pipe, and a driving mechanism for driving the cylinder to move up and down in the mounting box is arranged in the mounting box. By arranging the mounting box and the driving mechanism, the disc and the steam trap are driven to rise to the same horizontal height as the guide pipe, so that the steam trap is prevented from deviating during mounting; by arranging the reinforcing mechanism between the communicating pipe and the guide pipe, multiple reinforcing is achieved, the overall stability of the device is further enhanced, and unstable installation is avoided.

This application relates to the field of mechatronic installation technology and discloses a mechatronic installation positioning mechanism, including a work frame and a fixed frame. The upper side of the fixed frame is fixedly connected to uniformly distributed limiting components, which support and limit the movement of a connecting plate. The lower side of the limiting components is fixedly connected to a connecting plate. A push rod is fixedly connected inside the fixed frame, and a push block is fixedly connected to the output end of the push rod. A connecting block is fixedly connected to the upper side of the push block, and a connecting plate is fixedly connected to the upper side of the connecting block. A vertical plate is fixedly connected to the upper side of the connecting plate, and a clamping plate is fixedly connected to the upper side of the vertical plate. Anti-slip pads are fixedly connected to the adjacent sides of the clamping plates. This mechanism ensures high-precision positioning of mechanical components during installation, reduces errors, improves installation efficiency and accuracy, and enables the mechanism to operate efficiently, accurately, and reliably, providing good stability and operational safety.
