Abstract
The invention relates to an oil draining valve which comprises a valve clack and a valve body. The valve clack is inserted into the valve body and is in contact with the valve body. The contact faces include the conical face and the radial face. A conical face sealing ring is arranged at the position of the conical face where the valve clack is in contact with the valve body. The central oil draining valve is good in sealing effect.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of draining valve, relate in particular to a kind of for the central oil outlet valve on tank car.
Background technique
Existing central oil outlet valve mainly consists of valve body, flap, spring, valve gap etc.; The position that wherein flap contacts with valve body is the conical surface, can not effectively solve the problem of foreign body retention on sealing surface, and using effect is not good enough.
Summary of the invention
In order to solve the above-mentioned technical problem existing in background technique, the invention provides a kind of central oil outlet valve of good sealing effect.
Technical solution of the present invention is: the invention provides a kind of central oil outlet valve, comprise flap and valve body, described flap stretches in valve body and with valve body and contacts, and described surface of contact comprises the conical surface and sagittal plane; Its special way is: the conical surface place that described flap contacts with valve body is provided with conical surface seal circle.
Above-mentioned conical surface seal circle is O RunddichtringO.
The sagittal plane place that above-mentioned flap contacts with valve body is provided with sagittal plane seal ring.
Above-mentioned sagittal plane seal ring is O RunddichtringO.
The sagittal plane place that above-mentioned flap contacts with valve body is also provided with the wiper ring mutually parallel with sagittal plane seal ring.
Above-mentioned central oil outlet valve also comprises the flap guide sleeve that is arranged on flap bottom.
Advantage of the present invention is:
The invention provides a kind of central oil outlet valve, this central oil outlet valve is in order to solve the poor problem of sealing effect in prior art, the conical surface place specially contacting with valve body at flap is provided with conical surface seal circle, the sagittal plane place contacting with valve body at flap is provided with sagittal plane seal ring, makes the combination seal between flap and valve body reliable; Meanwhile, the sagittal plane place that the present invention contacts with valve body at flap is provided with the wiper ring mutually parallel with sagittal plane seal ring, and wiper ring can effectively be cleared up the foreign matter being trapped in radial sealing surfaces, guarantees the reliability of radial seal.
