Abstract

The whole close ring interface of the radial end face sealing piece in swing piston and mechanical piston is the next invention after the compressor end face sealing device of the swing piston which the patent application number is 200610082248.2. The thin metal sheet is as the junctional sheet between the sealing pieces. The notches are cut between the radial sealing sheet and the end face sealing sheet, the midline between the end sealing sheet and the end sealing small column which are inserted into the thin metal sheet to form the whole close ring interface. The structure has been tested in the sample machine in 2007, so it is used in the small, middle and big single swing piston two cylinders compressor; also it can be specially used in the whole ultra pressure piston in series with multi cylinders swing piston compressor which the patent number is 200610115894.4 or in the single or multi swing piston in series to form the two cylinders or multi cylinder four-cycle explosive motor which the patent number is 200610135808.6.

Description

Oscillating piston mechanical piston radial sealing parts end sealing parts full-closed ring connection

The oscillating piston mechanical piston radial sealing parts end sealing parts full-closed ring connection of technical field belongs to FO1C9/00 according to International Patent Classification (IPC), FO2B53/00, FO2B53/04.

The patent of invention that the background technique prior art is declared on May 15th, 2006 for the inventor: swing piston compressor end surface sealing device, number of patent application: 200610082248.2 follow-up invention.In the model machine of development, carried out improving design in April, 2007, perfect this new invention.

Summary of the invention oscillating piston mechanical piston end face and apex sealing strip are installed on the oscillating-piston [1].Straight Stamping Steel Ribbon, the handing-over of little garden post multiple tracks are adopted in end face seal, constitute multiple-sealed device.

Oscillating-piston [1] end face constitutes sealed air chamber by the little garden of end face seal post [2A], the little garden of end face seal opening post [3A], end face seal bar [5A], [6A], each gas leakage generally needs through 2 to 4 sealed air chamber, each air chamber all plays the sealing hypotensive effect, constitutes the excellent sealing to gas.

End face seal bar [5A] and apex sealing strip [4A] handing-over.Apex sealing strip [4A], end face seal bar [5A] center line are all by the oscillating-piston center line.End face seal bar [6A] center line all seals the center of little garden post [3A] by the little garden of end face seal post [2A], opening.The handing-over of above Sealing is the face contact, so the surface of contact of Stamping Steel Ribbon and cylinder body plane and garden cylinder is that face contacts.

The little garden of end face post [3A] except that and end face vertical bar shaped Stamping Steel Ribbon [6A] handing-over, still and apex sealing strip [4A] activity inlay handing-over.

End face seal bar [5A], [6A] groove depth are equal to the depth dimensions of sealing little garden post [2A], [3A].The depth dimensions of above Stamping Steel Ribbon all is equal to the degree of depth of the groove that matches.

Coil spring is placed in the equidistant boring of all bottom lands in the hole, as Stamping Steel Ribbon is outwards ejected.It is in order to prevent that coil spring from blocking the aperture when compressing that the structure of [8] expression spring eye among Fig. 2, aperture enlarge.

The vertical bar shaped Stamping Steel Ribbon is convenient to processing and assembling.Available line cutting process Stamping Steel Ribbon two ends can be formulated manufacturing procedure to given size and shape during single piece production during batch process except that the line cutting, press working procedure processing to given size and shape with machining.

Single-piece work end face seal bar [5A], [6A] manufacturing procedure are as follows:

1, dimensioned radial seal groove [4] in accordance with regulations.

2, with the dimensioned littler post hole, little garden [2], [3] than given size.

3, press oscillating-piston center line processing groove [5] to given size.

4, press hole [2], [3] center processing groove [6] to given size.

5, Stamping Steel Ribbon [5A], [6A] thickness is greater than groove depth, allocates seal groove [5], [6] back into and compresses (at the oscillating-piston end face assembly section tapped hole of subdrilling stationary platen in advance not with pressing plate.

6, hole [2], [3] are expanded to given size, process end face seal bar [5A], [6A] simultaneously to given size and shape.

7, end face seal bar [5A], [6A] grinding machine are milled to given size.

Hermetically sealed in order to realize, at apex sealing strip [4A] and end face seal bar [5A], adopt inserted little sheet metal [7A] between end face seal bar [5A], [6A] and sealing little garden post [2A], [3A], this thin slice is a tinsel, three-dimensional structure for amplifying is seen accompanying drawing 3.Go up at apex sealing strip [4A] earlier and cut groove, go up by [4A] at end face seal bar [5A] and cut the groove line, by the cutting of line line with line; Go up line by end face seal bar [5A], [6A] cutting groove at little garden post [2A], [3A] and carry out the line cutting, the sliding foil [7A] of allocating in the online then cutting groove.

Specific embodiments had been carried out the prototype design of single oscillation piston duplex cylinder compressor before declaring this project, and obtained success, the compressor of this kind structure is applicable to the light duty compressor of air displacement less than per minute 10 steres, air displacement is at the moderate-duty compressor of per minute 10 to 60 steres, and air displacement is on the large-scale compressor of 60 to 120 steres.Declared the binomial patent again in 2006: (1) integrated type super-large displacement ultrahigh pressure piston series connection multiple cylinder multiple level swing piston compressor, number of patent application 200610115894.4.(2) single or multiple oscillating-piston series connection is two cylinder or multicylinder four-stroke explosive motor, number of patent application: 2006101358086, and there has been this patent application to can be oscillating piston mechanical and on monopolistic market, the world, laid a sheet of world.
