Abstract
The invention discloses a valve ejector rod reinforced through spring strip fixing seats. The valve ejector rod comprises an ejector rod body and the spring strip fixing seats. One end of the ejector rod body is provided with an ejector pin. The other end of the ejector rod body is provided with an ejector cap. The ejector rod body is provided with an external thread. Lantern ring seats are arranged on the spring strip fixing seats. Internal threads are arranged on the inner side walls of the lantern ring seats. The lantern ring seats are in threaded connection with the external thread through the internal threads to be connected to the ejector rod body. The ejector rod body is provided with at least two spring strip fixing seats. The upper ends and the lower ends of the spring strip fixing seats are provided with spring strip fixing tables. Tension spring bodies are arranged between the spring strip fixing tables. By means of the manner, the valve ejector rod can be machined, the situation that the valve ejector rod vibrates and deforms when bearing larger stress is avoided, and the service life of the valve ejector rod is prolonged.
Description
Technical field

In a preferred embodiment of the present invention, described thimble, cast for integral type between described top cap with described push rod body and be connected.
In a preferred embodiment of the present invention, described top cap front-end face is a horizontal plane, and cap rear end, described top is a curved end, and cap rear end, described top curved end middle position is fixedly connected with described push rod body.
In a preferred embodiment of the present invention, described spring stationary platen protrudes and is arranged on described cover ring seat upper and lower end position, and the described spring stationary platen of described cover ring seat upper and lower end is symmetrically set.
In a preferred embodiment of the present invention, described draught spring body two ends are fixed on described spring stationary platen by screw, and the described draught spring body of described spring stationary platen upper and lower end is all horizontally disposed with.
The invention has the beneficial effects as follows: the present invention can process valve stem, produce when avoiding valve stem to be subject to larger stress vibration deformation etc. situation, draught spring physical efficiency between spring fixed base increases the tightening force of valve stem, strengthen stationarity, extend the working life of valve stem.
