Problems solved by technology

[0002] The existing oil injection valve mainly pushes the spring assembly by external force to open the oil injection channel for oil injection. When the oil injection stops, the external force is removed, and the reset is realized only by the spring force, and the operation sensitivity is poor.
Moreover, the internal structure of the oil injection valve is complex, and once a component fails, it is difficult to repair and replace, and the entire oil injection valve is directly scrapped

Abstract

The invention discloses a forged steel oil injection valve. The forged steel oil injection valve comprises a valve body, a valve cover and a bottom cover; an oil storage cavity and a piston movement cavity are formed in the valve body; the oil storage cavity is positioned at the top of the piston movement cavity; the top of the oil storage cavity is open; the bottom of the oil storage cavity communicates with the piston movement cavity through a through hole; the bottom of the piston movement cavity is open; a piston is arranged in the piston movement cavity; a first spring is fixed to the topof the piston; the piston moves towards the bottom of the valve body through the first spring; a ventilating opening and an oil outlet are also formed in the valve body; the valve cover is mounted atthe top of the valve body; an oil injecting opening which communicates with the oil storage cavity is formed in the valve cover; the bottom of the valve cover is connected with an oil storage cavitystop cover through a second spring; the oil storage cavity stop cover shields the through hole through the second spring; and the bottom cover is mounted at the bottom of the valve body. According tothe forged steel oil injection valve, the starting and stopping of oil injecting are completed through the gravity of a pneumatic combination part and the elastic force of the springs, so that an oilinjecting operation is more sensitive.

Description

technical field [0001] The invention relates to the technical field of oil injection valves, in particular to a forged steel oil injection valve. Background technique [0002] The existing oil injection valve mainly pushes the spring assembly by external force to open the oil injection channel for oil injection. When the oil injection stops, the external force is removed, and the reset is realized only by the spring force, and the operation sensitivity is poor. Moreover, the internal structure of the oil injection valve is complex, and it is difficult to repair and replace the parts once they fail, and the entire oil injection valve is directly scrapped. [0003] Therefore, it is an urgent problem for those skilled in the art to provide a forged steel oil injection valve with simple structure, easy disassembly and sensitive operation. Contents of the invention [0004] In view of this, the present invention provides a forged steel oil injection valve, which realizes the s...
