Fast insertion type manual valve for vehicle

Abstract

The invention relates to a valve, in particular to a fast insertion type manual valve for a vehicle. The fast insertion type manual valve adopts the following technical scheme that the fast insertion type manual valve for the vehicle comprises a valve body, a valve cover, an air inlet, a silencer installing opening and a plurality of air outlets, wherein the air inlet is formed in the valve body, a valve cavity is arranged in the valve body, a manual pull rod capable of driving a valve core is arranged in the valve cavity, the inner wall of the valve cavity are arranged plurality of flow division cavities, the plurality of flow division cavities are respectively communicated with the air inlet and the silencer installing opening, the valve core is a piston, the piston is in coaxial arrangement with the valve cavity of the valve body, sealing bodies capable of sealing and plugging the air inlet, the silencer installing opening or the air outlets are arranged on the outer wall of the piston at intervals, the manual pulling rod is arranged vertically to the axis of the valve cavity, and extends into the valve cavity through the valve cover, in addition, one end, extending into the valve cavity, of the manual valve rod is hinged to the piston, and a balance regulating mechanism is arranged between the valve cover and the manual pulling rod. The technical scheme is adopted, and the invention provides the fast insertion type manual valve for the vehicle with the advantages that the structure is simple, the operation is convenient, and the size is small.

Description

technical field [0001] The invention relates to a valve, in particular to a quick-insert manual valve for a vehicle. Background technique [0002] The manual valve for vehicles mainly uses compressed air to control the translation of the shift fork of the power take-off of the automobile gearbox to make the coupling mesh and transmit the force of the power take-off window to the gear pump, and the oil of the gear pump pushes the oil cylinder to rise and fall to control the car The lifting of the container realizes the self-unloading function of the vehicle. [0003] The traditional vehicle manual valve is mainly composed of a valve body and a manual pull rod arranged on the valve body. The valve body is provided with an air inlet and a number of air outlets. There are at least two sets of valve cores driven by the manual pull rod in the valve body. Conduction is implemented between the air inlet and the air outlet through the driving of the manual pull rod. Since there are...

AI Technical Summary

Problems solved by technology

Since there are multiple sets of spools inside, the linkage between the manual pull rod and the spool is relatively complicated, and the installation process of the spool is cumbersome and occupies a large area. Due to its many linkage relationships, it is prone to failure during operation.
