Abstract
The utility model discloses a valve rod seal circle of solenoid valve, including the body, the body is equipped with central through-hole, the body includes integrated into one piece's cylinder section and frustum section, the body one end of cylinder section one side is equipped with the tight sealed face in terminal surface top, cylinder section outer wall is equipped with an oil storage tank, and the oil storage tank both sides form the sealed face of twice bellied valve body, frustum section outer wall is established to the conical surface. Compared with the prior art, the utility model the advantage be: the utility model discloses a set up an oil storage tank on the body, make lubricating oil can keep in this department, form the effect of slowly-releasing lubricating oil, the life of the sealing washer of extension greatly.
Description
Technical Field
The utility model relates to a sealing washer especially relates to a valve rod seal of solenoid valve.
Background
And a sealing ring is arranged on the valve rod of the electromagnetic valve, moves along with the valve rod and rubs with the valve body. The existing electromagnetic valve rod sealing ring has no oil storage structure, the lubricating effect is poor, the sealing ring is easy to dry, deform, age, damage and the like, and the sealing failure is easy to cause. Therefore, it is an urgent problem to be solved by those skilled in the art to develop a valve rod sealing ring of an electromagnetic valve.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned not enough, provide a valve rod sealing washer of solenoid valve.
The above object of the present invention is achieved by the following technical solutions: the utility model provides a valve rod seal circle of solenoid valve, includes the body, and the body is equipped with central through-hole, the body includes integrated into one piece's cylinder section and frustum section, the body one end of cylinder section one side is equipped with the terminal surface and pushes up tight sealed face, cylinder section outer wall is equipped with an oil storage tank, and the oil storage tank both sides form the sealed face of the bellied valve body in twice, frustum section outer wall is established to the conical surface.
The utility model discloses wholly form three sealings, the sealing washer is following the valve rod and is moving together, and when rubbing with the valve body, the lubricating oil in the oil storage tank just can play a slowly-releasing effect, and duration is of a specified duration, helps prolonging the life of sealing washer.
Compared with the prior art, the utility model the advantage be: the utility model discloses a set up an oil storage tank on the body, make lubricating oil can keep in this department, form the effect of slowly-releasing lubricating oil, the life of the sealing washer of extension greatly.
Drawings
