Abstract
Dynamic sealing, including end fixing component, elastic diaphragm and base securing component are moved back and forth the invention discloses a kind of diaphragm no-leakage；Elastic diaphragm is connected with end fixing component and base securing component respectively.The present invention using elastic diaphragm can elastic telescopic the characteristics of, the process of its elastic telescopic can provide a displacement and be moved back and forth for lever, at the same completely completely cut off barrier film media of both sides, so as to realize the reciprocating motion dynamic sealing of complete No leakage.
Description
Technical field
The invention belongs to the technical field of dynamic sealing, and in particular to a kind of diaphragm no-leakage moves back and forth dynamic sealing.
Background technology
As the development and environmental protection of microtechnic are by today of pay attention to day by day, to the requirement more and more higher for sealing.Liquid
Due to its strength greatly, Stability Analysis of Structures is increasingly widely used in all trades and professions with the features such as being easily assembled for pressure or air pressure.Especially
For chemical industry, core industry and it is some other be related to for the industry of dangerous material, to sealing often require that zero leakage, i.e., not
A bit dangerous material are allowed to leak out, but in industrialized process, the operation to dangerous material also tends to be realized by machine,
This requires that a bit leakage can not be allowed in motion process.The device of rotary dynamic seal can be realized at present has machinery close
Envelope, magnetic seal etc..Still without a kind of sealing device that can realize moving back and forth zero leakage.And if in fact, all motion structures
The all rotary motions of part are come if driving, it will greatly increase equipment complexity and cost.Our diaphragm no-leakage is past
Dynamic sealing is moved again, accomplishes reciprocating zero leakage, the Machine Design in some fields can be just greatly simplified, so as to reduce life
Cost is produced, is increased productivity, it is often more important that protect environment, and simple in structure and low in cost, be adapted to high-volume and promote.
For precision optical machinery Sports Field, existing hydraulic mechanism is often not participating in precision optical machinery motion, just
Because existing reciprocating dynamic seal is not carried out zero leakage, cause kinematic accuracy inadequate.And needed if being driven with motor big
Amount transmission mechanism, often makes complex structure, and our diaphragm no-leakage moves back and forth dynamic sealing, just can directly ensure hydraulic pressure
Reciprocating accuracy and the stability for elapsing over time.
The content of the invention
A kind of diaphragm no-leakage reciprocating motion is provided and is moved it is an object of the invention to avoid of the prior art not enough
Sealing, its by the use of elastic diaphragm stroke as lever displacement, while completely cutting off barrier film media of both sides completely, realize reciprocal fortune
Dynamic zero leakage.
The purpose of the present invention is achieved through the following technical solutions：
A kind of diaphragm no-leakage is provided and moves back and forth dynamic sealing, including structure is fixed in end fixing component, elastic diaphragm and bottom
Part；Lever is connected by the end fixing component and elastic diaphragm with base securing component, when hydraulic cylinder or supercharge cylinders,
Promote base securing component to drive lever or push directly on lever to realize moving back and forth；Or also may be used by other powered levers
Realize the reciprocating motion that both sides are fully sealed.
Brief description of the drawings
Using accompanying drawing, the invention will be further described, but embodiment in accompanying drawing is not constituted to any limit of the invention
System, for one of ordinary skill in the art, on the premise of not paying creative work, can also obtain according to the following drawings
Other accompanying drawings.
Fig. 1 the structural representation of present invention.
Fig. 2 is first kind implementation method of the invention.
Fig. 3 is Equations of The Second Kind implementation method of the invention.
Fig. 4 is top view of the present invention.
Specific embodiment
In order that those skilled in the art more fully understands technical scheme, it is below in conjunction with the accompanying drawings and specific real
Apply example the present invention is described in further detail, it is necessary to explanation, in the case where not conflicting, embodiments herein and
Feature in embodiment can be mutually combined.
As shown in figure 1, structure is fixed in the diaphragm no-leakage reciprocating movement sealing described in the embodiment of the present invention one, including end
Part 1, elastic diaphragm 2, base securing component 3.
First kind specific embodiment as shown in Figure 2, its lever 4 passes through end fixing component 1 and elastic diaphragm 2 and bottom
Fixing component 3 is contacted.Its original state is that the existing part of elastic diaphragm 2 extends, when having hydraulic pressure or other dynamic actions in bottom
When in fixing component 3, base securing component 3 will promote lever 4 to move back and forth, elastic diaphragm 2 and end fixing component 1 and
Base securing component 2 is actually static seal state, is capable of achieving zero leakage, and the media of both sides of elastic diaphragm 2 is in motion process
Completely cut off completely by elastic diaphragm 2, so as to realize moving back and forth zero leakage dynamic sealing.
Equations of The Second Kind specific embodiment as shown in Figure 3, its lever 4 passes through end fixing component 1, elastic diaphragm 2 and bottom
With elastic diaphragm be connected lever 4 as adpting flange by fixing component 3, base securing component 3.Its original state is elastic diaphragm
Compression extends, and when having other dynamic actions of hydraulic oil in lever 4 when, pushes directly on lever and moves back and forth.Bottom is consolidated
Determine to be actually static seal state between component 3 and lever, be actually between elastic diaphragm 2 and end fixing component 1 quiet close
Envelope state, is capable of achieving zero leakage.And the media of both sides of elastic diaphragm 2 is completely cut off completely in motion process by elastic diaphragm 2, so that real
Now move back and forth zero leakage dynamic sealing.
Many details are elaborated in above description in order to fully understand the present invention, but, the present invention can be with
Other modes described here are different from using other to implement, it is thus impossible to be interpreted as limiting the scope of the invention.
In a word, although the present invention lists above-mentioned preferred embodiment, although it should be noted that those skilled in the art
Member can carry out various change and remodeling, unless such change and remodeling deviate from the scope of the present invention, otherwise should all wrap
Include within the scope of the present invention.
