Abstract
The utility model provides an inblock cast power cutting pilot control valve body type pilot valve which adopts an inblock cast power cutting pilot control valve body structure. The pilot valve is characterized in that a main valve body of the pilot valve and a pilot control valve body are cast into one part. The inblock cast power cutting pilot control valve body type pilot valve has the advantages of being simple in structure, easy to process, reliable in working, and not prone to valve blocking and leakage.
Description
Technical field
The utility model relates to a kind of control valve of controlling for gearbox, adopts the cast inblock power cut to control the guide valve blocks structure, have simple in structure, easily processing, reliable operation is not easy the advantage of card valve and leakage.
Background technique
The control valve of small-sized loader gear box use at present is the integrated valve block of three selector valves, and it is hand-operated direction valve that two selector valves are wherein arranged, and the another one selector valve is that the selector valve of pilot control structure is called the power cut valve.The power cut valve is the pilot control change-over valve of gas, liquid pilot control, is used for cutting off the fuel feeding of gearbox when loader brakes, to cut off the power output of loading machine gearbox.The structure of generally using now is to install in addition a pilot control valve body with being threaded on the main valve body of casting.As shown in Figure 1, A is that main valve body, B are the pilot control valve body, and main valve body adopts pig iron casting, and the pilot control valve body adopts round steel to process, and the pilot control valve body adopts to be threaded and is arranged on main valve body.This complex structure, number of spare parts is many, and processing technology is complicated, and easily blocks valve and leakage.
Summary of the invention
In order to overcome the shortcoming of existing control valve, technical solutions of the utility model are that control valve adopts cast inblock power cut pilot control valve body structure, and control valve and pilot control valve body are cast into a part.This scheme has simple in structure, easily processing, and reliable operation is not easy the advantage of card valve and leakage.
Description of drawings
Fig. 1 is the power cut valve arrangement sectional drawing of existing control valve.
The power cut valve arrangement sectional drawing of Fig. 2 the utility model control valve.
