Description
Technical field
The utility model relates to a kind of integrated push rod seal assembly, specifically a kind of industrial control valve actuator black box.
Background technique
Along with economic development, the industrial automation controlling level is in continuous improve, thus to the requirement of the reliability of modulating valve in the process control also in continuous raising.This just also has higher requirement to valve actuator.In prior art, existing pneumatic valve final controlling element push rod seal place generally adopts the fluorine rubber guiding to add O shape and encloses built-in sealing configuration, and fluorine rubber is easily aging, and guide effect is not good, and this structure O shape circle is changed difficulty, thereby valve is broken down.Even cause complete equipment to be stopped transport, cause the tremendous economic loss.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of its to have the reliable sealing guide structure, be convenient to keep in repair, change the valve actuator black box of quick-wear part, can effectively reduce valve actuator in running, occur guiding not steadily, gas leak phenomenon, guarantee the stable performance of valve actuator, guarantee that apparatus moves safely and smoothly, enhance productivity.
The technological scheme that provides according to the utility model, integrated push rod seal assembly comprises interior O shape circle, sliding bearing, cylinder cap, outer O shape circle, axle sleeve, dust ring, screw, pressing plate and push rod, O shape circle, sliding bearing, outer O shape circle embed in the axle sleeve in integrated mode in described, O shape circle is installed between axle sleeve and the push rod in described, forms first seal structures; Outer O shape circle is installed between cylinder cap and the axle sleeve, forms second seal structures; Described dust ring is installed between axle sleeve bottom and the push rod, forms three seal structures; Compress axle sleeve by pressing plate, pressing plate is fixed on the cylinder cap with screw.
Compared with the prior art the utility model has the following advantages:
1, owing to adopt the composite material sliding bearing guiding can effectively prevent the throw-out lever tilt phenomenon, the final controlling element degree of regulation improves 30%;
2, owing to adopt external seal with O ring structure, be convenient to the on-the-spot O of replacing type circle, solved built-in O type circle sealing configuration and changed consuming time, a consumption power difficult problem;
3, the sealing configuration of this valve actuator black box is safe and reliable, favorable sealing property, and accident rate reduces by 80%;
4, this valve actuator sealing structure assembly is simple and reliable, easy to maintenance.
Description of drawings
Fig. 1 is the utility model structure user mode figure.
Fig. 2 is the utility model integrated push rod seal assembly structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 2, integrated push rod seal assembly is made of interior O shape circle 1, sliding bearing 2, cylinder cap 3, outer O shape circle 4, axle sleeve 5, dust ring 6, screw 7, pressing plate 8 and push rod 9 parts.
The interior O shape circle 1 of sealing assembly, sliding bearing 2, outer O shape circle 4 are embedded in the axle sleeve 5 in integrated mode, and integral installation is fitted in the cylinder cap 3, and dust ring 6 is installed, and compresses axle sleeve 5 by pressing plate 8, utilizes screw 7 that pressing plate 8 is fixed on the cylinder cap 3,
Sealing assembly sealing system is by interior O shape circle 1, outer O shape circle 4 and the assembling of dust ring 6 three seal structures.Wherein interior O shape circle 1 is installed between axle sleeve 5 and the push rod 9, is first seal structures of sealing assembly.Outer O shape circle 4 is installed between cylinder cap 3 and the axle sleeve 5, is second seal structures, and the main effect of dust ring 6 is to prevent that external dust or foreign material from entering sliding bearing 2 inside, and the wearing and tearing push rod causes seal failure, also plays the effect of three seals simultaneously.
The guide elements sliding bearing 2 of sealing assembly is made up of composite material, with the cemented carbide thin plate is matrix, the outside adheres to one deck tin bronze, and its internal surface rolling one deck FDB organic substance and lead mixture have substituted the traditional guide elements based on copper material, it is little that this sliding bearing has a friction factor, wear-resisting corrosion resistance is superior, and advantages such as oil-free lubrication play accurate leading role, can effectively improve push rod working life, reduce maintenance cost.
The sealing assembly is when changing fragile part, simply, quick and easy, need not other component of dismounting final controlling element, unclamp housing screw 7, directly O shape circle 1, sliding bearing 2, outer O shape circle 4, axle sleeve 5 are split out in the mode of integral body, pack in the cylinder cap 3 in the mode of integral body again after changing, time saving and energy saving.
The utility model working principle:
The utility model adopts sliding bearing 2 to do accurate guiding, and inside and outside O shape circle is done effective sealing, and push rod 9 pumps, and realizes open and close, the adjusting action of valve.
The utility model as seal element, by the thrust that source of the gas produced, is realized moving up and down of push rod with O shape circle, to the action generation driving action of valve.
