Problems solved by technology

In these cases, the sealing performance between the valve body and the valve core of the control valve cannot be guaranteed, and dust, water and other sundries can easily enter the valve body, causing damage to the valve, thus increasing the performance requirements for the valve itself
If the control valve is completely sealed, it is cumbersome to disassemble, replace, and clean the valve body or core, and each maintenance requires the control valve to be removed from the frame
However, the method of sealing the valve body alone is extremely complicated and the cost is high.

Abstract

The invention provides a valve component, which comprises a valve, a bracket and a protective cover, wherein the valve comprises a valve body and a valve core capable of moving in the valve body; the bracket comprises a bracket body for installing the valve, as well as a connecting plate stretching out sidewise from the bracket body; the valve core passes through a hole on the connecting plate; and the protective cover surrounds the valve core and covers the valve body. The valve can be a movable-type mechanical speed change valve, a brake valve, a steering valve or other valve.

Description

technical field [0001] The invention relates to a valve assembly for a machine. Background technique [0002] Many types of valves are used on machines, especially control valves such as hydraulic steering valves, transmission valves and brake valves in mobile machinery. In the past, when the control valve of a mobile machine was installed on the frame (such as the bottom of the cab of the mobile machine), the control valve was often installed directly on the frame by, for example, threaded fasteners, or by simple The bracket mounts the control valve to the frame. In these cases, the sealing performance between the valve body and the valve core of the control valve cannot be guaranteed, and dust, water and other sundries can easily enter the valve body, causing damage to the valve, thus increasing the performance requirements for the valve itself. If the control valve is completely sealed, it is very troublesome to disassemble, replace, and clean the valve body or valve co...
