Abstract

The invention discloses a locking type angled plug door, which comprises a valve body; an adjusting handle, one end of which is rotatably connected with the valve body, and is used to adjust the switch state of the valve body; The ground is locked and connected with the valve body, and when the locking component is locked and connected with the valve body, the adjusting handle and the valve body are relatively fixed. The locking part of the present invention is movably arranged on the adjusting handle, which is convenient for installation and easy to lock the valve body; in addition, when the locking part breaks down, it is convenient for maintenance and replacement; moreover, the locking effect is visible, preventing locking Inadequately causing the valve body to close unexpectedly.

Description

technical field [0001] The invention belongs to the field of train braking devices, and in particular relates to a locking type angled plug door. Background technique [0002] At present, train brakes in the international railway system all adopt the air brake mode. The train relies on the train tube connecting all the vehicles of the whole train to control the train to ease and brake. When the train tube is filled with air to a constant pressure, the train brakes Relief, train pipe decompression (exhaust air) train braking deceleration or parking, the train pipes of each vehicle are connected and shut off with other vehicle train pipes through the angled plugs installed at the two ends of the vehicle. After the entire train formation and connection is completed, the knuckle plugs of the locomotive and all connected vehicles should be in the open state, and the train pipes of the whole train are controlled through the locomotive air source system to fill and discharge air, s...
