Abstract
The utility model relates to an automatic compensating sealing device, which comprises a valve body, a valve rod and a sealing ring. The utility model is characterized in that the annular notch of the valve body or the valve rod, which is near an outlet and is used for positioning the sealing ring, has a triangular cross-section. The utility model has the advantages of durability, long service life, no maintenance, wide applied ranges, good sealing effect, energy saving, safety, and reliability.
Description
The utility model relates to the seal arrangement of a kind of liquid, gas, in particular for the seal arrangement on the valve that valve rod and valve body structure are arranged.
At present, known liquid, gas seal valve are equipped with seal ring between the outlet position of its valve body and the valve rod, the sealing circle places in the annular groove of valve rod near the outlet position, present employed seal ring is generally O shape, and the cross section of circular groove then is a rectangle, and the cooperation of this structure is tight inadequately, especially when seal ring is aging, easier generation slit can not compensate automatically, leaks thereby produce, waste energy, even industrial production and people's lives are brought serious harm.
The purpose of this utility model provide a kind of durable, life-span long, need not keep in repair, using scope is wide, good sealing effect, can compensate the slit automatically, do not leak, thereby can save the reliable automatic compensation sealing device of energy security.
The purpose of this utility model is achieved in that
The utility model comprises valve body, valve rod and seal ring, it is characterized in that: valve body or valve rod are triangle near the cross section that the outlet position is used to put the annular groove of seal ring.
The utility model is owing to adopt said structure, when certain pressure is arranged in the valve body, valve rod is subjected to the power to extrapolation, and the circular groove of its triangular cross section makes it produce distortion for the certain extruding force of O shape sealing, pressure is big more, be out of shape big more, thereby be pressed in tightly between valve outlet position and the valve rod, automatically compensated the space, can tightly seal too even O-ring seals is aging, not leak.The utility model does not waste energy, and manufacturing is easy, durable, the life-span is grown, do not leak, need not keep in repair.Can be used for fields such as valve, water pump, air-conditioning; In addition, all have a shape valve rod and low position of rotating to use.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model embodiment one a structural drawing.
Fig. 2 is the utility model embodiment two a structural drawing.
See Fig. 1, the utility model is made up of valve body 1, valve rod 2 and O RunddichtringO 3, and its valve rod 2 is a triangle near the cross section that outlet positions are used to put the annular groove 21 of O RunddichtringO.
See Fig. 2, annular groove 11 is positioned at the close outlet position of valve body 1, and its cross section is a triangle, and the O RunddichtringO places in the annular groove 11.Its working principle is identical with embodiment one.
