Abstract
The utility model relates to a combined type sealing ring for a control valve. A dustproof ring is arranged at one side of the sealing ring along the axial direction, a Y-shaped sealing ring is arranged at the other side of the sealing ring, an inner lip of the Y-shaped sealing ring and a dustproof lip of the dustproof ring are contacted with a sealing surface, and a connection surface of a lip edge of the inner lip and the lip edge of the dustproof lip is an inwards concave arc surface. The combined type sealing ring for the control valve has the advantages of being largely improving the overall reliability of products, effectively preventing external impurities, dirt and harmful materials from entering an inner cavity of an executing mechanism, preventing medium inside the valve or the executing mechanism from escaping, and enabling the overall quality to be reliable and the performance to be more stable. The combined type sealing ring for the control valve is reasonable in structure, is definite in function, achieves a bi-directional sealing effect, saves cost, and achieves positive progress at the same time.
Description
Technical field
The utility model relates to the control valve of a kind of recloser or adjusting, especially relates to a kind of control valve combined type packing ring.
Background technique
At present, control valve is as the performance element of industrial automation system, actuator's push rod outgoing position and valve rod outgoing position at it are to adopt traditional O RunddichtringO basically, the defective of this structural type is: traditional O RunddichtringO edge shape curls inward, when the upper and lower motion of the valve rod on actuator's push rod and the valve body, bring the impurity or the dirt in the external world into actuator's inner chamber and body cavity easily, thereby cause actuator's fault even damage, also can influence the various aspects of performance of control valve.
Summary of the invention
The purpose of this utility model is to provide a kind of control valve combined type packing ring at the prior art deficiency.Combined seal structure is more reasonable, can prevent that extraneous impurity or dirt from bringing actuator's inner chamber and body cavity into.
The purpose of this utility model realizes by following measure: a kind of control valve combined type packing ring, it is characterized in that, a seal ring side vertically is that dust ring, opposite side are y-type seal ring, the epipharynx of described y-type seal ring contacts with sealing surface with the dust excluder lips of dust ring, and the junction surface of epipharynx antelabium and dust excluder lips antelabium is the cambered surface of an indent.
Compared with prior art, the control valve combined type packing ring that the utility model proposes, have following advantage: the product whole reliability has improved greatly, can prevent effectively introduced contaminants, dirt, etc. harmful matter enter actuator's inner chamber, the medium that can prevent valve or actuator inside again leaks, and makes that the control valve total quality is reliable, performance is more stable.The effect that this product structure is reasonable, effect is clear and definite, obtained two way sealed has also been saved cost simultaneously, has obtained positive progress.
Description of drawings:
Fig. 1 is the embodiment's schematic representation that the utility model proposes.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated: Fig. 1 is the embodiment's schematic representation that the utility model proposes.Among the figure, a kind of control valve combined type packing ring, a seal ring side vertically is that dust ring 1, opposite side are y-type seal ring 2, and the epipharynx 21 of described y-type seal ring contacts with sealing surface with the dust excluder lips 11 of dust ring, and the junction surface of epipharynx 21 antelabium and dust excluder lips 11 antelabium is the cambered surface of an indent.The epipharynx that inner concave arc surface in this structure more helps y-type seal ring contacts with sealing surface with the dust excluder lips of dust ring, and compensates automatically after wearing and tearing, has prolonged working life effectively.
Mode of execution of the present utility model has been described above in conjunction with the accompanying drawings; the structure that embodiment provides does not constitute restriction of the present utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in related domain.
