Description of the new type: [Technical field to which the new type belongs] This creation is about a floating oil seal structure, which is especially used to provide a compressor to prevent the high-pressure fluid from flowing backward when the compressor is stopped, and can reach the pressure equalization of the high-pressure cavity. [Previous technology] The known oil seal structure is often used in the structure of the compressor to output high pressure fluid_, so as to prevent the high pressure fluid from flowing back during shutdown. Such transmission lines typically yixian seal lid structure, when the high pressure fluid output, high pressure fluid can directly open the flip lid, and the compressor is stopped, the high pressure fluid backflow which will flip cover is closed to prevent high pressure fluid to achieve reverse the purpose of those flows. However, such a configuration in which the high pressure chamber will be closed, so that the high pressure chamber can not release high pressure fluid to the pressure chamber of which a relatively low pressure of the compressor so that when the compressor is turned off and then, the compression High-pressure gas outlet big load, thus causing instantaneous energy consumption will increase to start the compressor. [New content] The main purpose of this creation is to provide a floating oil seal structure to prevent the backflow of high-pressure fluid and to reduce the energy consumption at startup. To achieve the above object of the present writing, this writing one kind of floating oil-based structure, which is mainly disposed a compressor and a high pressure chamber in a closed housing, the cavity having a high pressure chamber based fluid output port of the compressor train may Produces a compressed fluid and outputs it through its high-pressure 5 M267348 outflow hole, and the high-pressure outflow hole is provided with a fluid check structure, and includes: a high-pressure flow port formed through the high-pressure cavity and used to cooperate with the high-pressure outflow of the compressor aperture; and a check valve, the bottom line is formed at least into an empty cartridge guiding holes, and forming one of the floating plate slidably along the inner wall surface of the floating plate is formed based on at least one plate of the guiding holes, the guiding holes formed on the lower guide holes is offset, such that the check valve under a high-pressure guiding holes communicating hole flows out of the compressor, but the high-pressure fluid flow from the high pressure port as not reverse flow back to the compressor of the compression chamber. In order to make those skilled in the art understand the purpose, characteristics and effects of this creation, Zlu uses the following specific examples and the accompanying drawings to explain this creation in detail as described below. one kind of floating seal structure provided, which mainly provide the compressor is formed by a fluid non-return structure. See FIG. 1 and 2 show one of the floating seal configuration of the present embodiment Creation than Lu Jia embodiment, (1) the outside of the main housing in a closed system to form a high pressure chamber of the compressor (13 (11) ) and a scroll means (15), wherein the pressure chamber (13) based a cavity, and forming a fluid communication with the exterior of the output port (13a) to the housing (11); and the scroll means (15) a compression chamber formed lines (13b), for generating a high pressure of the compressed fluid, and through its high-pressure outflow hole (15a) by the output, and is provided at the high-pressure outflow hole (15a) has a non-return fluid structure (10). The check structure (10) includes: a high-pressure flow port (101) formed through the high-pressure cavity (13) and used to cooperate with the high-pressure outflow of the scroll mechanism (15) 6 M267348 hole (15a); (103) is a hollow columnar structure formed around the high-pressure outflow hole (15a) of the scroll mechanism (15) and extending upward; and a check valve (105) is provided at the high-pressure flow port (1 〇1) and the accommodating tank (103), so that the high-pressure circulation port (101) communicates with the accommodating tank (103), but the high-pressure fluid will not flow back from the high-pressure circulation port (101) back to the scroll mechanism ( 15) in the compression chamber (13b). In the aforementioned check structure (10), the check valve (105) is a hollow cylinder with at least a lower diversion hole (105a) formed at the bottom, and a floating plate (105b) that can slide along the inner wall surface. The floating plate (105b) is a plate body forming at least one upper diversion hole (io5c), wherein the projection position of the upper diversion hole (105c) is related to the lower diversion hole (io5a). ) Dislocation. In addition, the check valve (105) is installed in the accommodation groove (103), and can slide along the inner wall surface of the accommodation groove (103), while the check valve (105) and the accommodation A sealing element (105d) is provided between the grooves (103) to prevent fluid leakage. The distance that the accommodation groove (103) extends upwards is the highest position that can guide the check valve (105) to slide along the inner wall of the accommodation groove (103), which is enough to contact the high-pressure circulation. Mouth (101). Wherein, there may be a gap between the top end of the cylindrical structure φ of the receiving groove (103) and the bottom of the high-pressure cavity (13), so that when the check valve (105) descends, the high-pressure circulation The port (1 () 1) can communicate with the lateral space inside the compressor⑴. "For the operation of the floating plate shown in Figures 1, 2, and 3, see Figure 1 ~ When the high-pressure fluid produced by Tutian's coiling mechanism (15) leaks from the high-pressure outflow hole (⑸), the pressure w will pass through the stop Counter valve ⑽) below the guide hole (1 core), and push the floating plate (delete) so that the piece of ocean moving plate ⑽ touches the bottom of the check valve (he) to form a considerable space, 7 M267348 causes the fluid to continue to pass through the upper guide Hole (105c) and flow through the high-pressure flow port (101) into the high-pressure cavity (13). Conversely, when the scroll mechanism (15) stops generating high-pressure fluid, the high-pressure fluid in the high-pressure cavity (13) will flow through The high-pressure flow port (101) pushes the floating plate (105b) so that the floating plate (105b) is in close contact with the bottom of the check valve (105), causing the fluid to continue to pass through the bottom of the check valve (105). The lower diversion hole (105a), that is, does not enter the scroll mechanism (15). In the aforementioned closed casing (11), at least in part, it is composed of a casting and forms the high-pressure cavity (13), and The high-pressure cavity (13) runs through to form a high-pressure flow port (101), which is matched with the high-pressure outflow hole (15a) of the scroll mechanism (15). The non-return valve (105) is simultaneously subjected to the high-pressure fluid output from the high-pressure outflow hole (15a) in the scroll mechanism (15), and along the inner wall surface of the accommodation groove (103), faces the high-pressure flow port ( 101) sliding; see Figure 1, when the pressure of the high-pressure outflow hole (15a) is insufficient, the high-pressure chamber (13) still has considerable pressure, and the check valve is pushed through the high-pressure flow port (101). (105) Along the internal wall surface of the accommodation groove (103), the reverse high-pressure flow port (101) slides, so that the high-pressure fluid does not pass through the check valve spring (105) and flows to the side inside the compressor (1). the space in order to achieve the effect of the internal pressure of the average pressure of the compressor ° see Figure 4 is presented as a further preferred embodiment the floating seal structure creation, where the previous embodiment differs from the embodiment in that the present embodiment The design of the check valve (105) is different, 'wherein' the check valve (105) has a lower flow hole (i5a), and the floating plate (105) is disposed in the check valve (105). 105b) having U〇5a) upper guiding holes (1〇5 (at least one guide hole (105c), while the lower guiding holes;) Dislocation due to 8 M267348 Therefore, when the high pressure fluid generated by the compressor (1) leaks from the high pressure outflow hole (15a), this high pressure fluid will pass through the guide hole (105a) below the check valve (105), and Push the floating plate (105b) so that the floating plate (105b) and the bottom of the check valve (105) form a considerable space, causing the fluid Jibin to pass through the lower diversion hole (105a) at the bottom of the check valve (105). ) And flow through the high-pressure flow port (101) 'into the high-pressure chamber (13). Conversely, when the compressor stops generating high-pressure fluid, the high-pressure fluid in the south-pressure chamber (13) will flow through the high-pressure flow port ( 1〇1), while pushing the floating plate G05b), so that the floating plate (105b) is in close contact with the bottom of the check valve (105), so that the fluid cannot continue to pass through the bottom of the bottom of the check valve (105) guiding holes (1〇5 phantom, i.e. does not enter the compression chamber Calls (13b) in. Floating seal structure of the present writing, the following effects: 1. The structure of the floating seal created, which is based on the formation of the structure constituting the guide hole guiding holes are formed through the floating check valve plate, and by high pressure driving fluid can be formed in the forward pass and the backward of the check barrier structure. 2. In the floating oil seal structure created by this creation, the check valve can be a floating structure, so that when the compressor outputs high-pressure fluid, the check valve can rise up to communicate with the high-pressure flow port, and when the compressor stops outputting high-pressure fluid, check valve will drop, so that the pressure in the high pressure chamber of the relief to the space between the compressor and the closed housing, and enhance system pressure balancing speed. Therefore, when the compressor is turned off and then on again, the load at the south pressure outlet of the compressor is not large, and the purpose of reducing the energy consumption of the compressor at startup can be achieved. The floating oil seal structure provided by this creation is at least partially composed of castings in the closed shell and forms the high-pressure cavity. Therefore, the number of assembly components can be reduced in M267348, and the requirements for assembly accuracy are reduced.
