Abstract
A sealing rubber for preventing gas leakage of compressor is composed of a top end inserted in the tube of liquid tank, a tubular trunk with rough surface in contact with the inner surface of said tube, and a flange end, and is prepared through making a mould, and moulding. Its advantages are tight installation, and high sealing performance.
Description
Technical field
The present invention relates to prevent in a kind of compressor the caulking gum and the manufacture method thereof of gas leakage, particularly relate to the caulking gum and the manufacture method thereof that prevent gas leakage in a kind of difficult drop-off and the stopping property good compression machine.
Background technology
Fig. 1 is the compressor arrangement synoptic diagram of prior art.Fig. 2 is the caulking gum stereographic map among Fig. 1.As shown in Figure 1 and Figure 2, the compressor of prior art comprises compressor body 5; The container for storing liquid 4 that compressor body 5 sides are provided with; The container for storing liquid conduit 2 that container for storing liquid 4 is provided with above; The cat head conduit 3 that compressor body 5 is provided with above; Be inserted in the caulking gum 10 that can prevent in container for storing liquid conduit 2 and the cat head conduit 3 that nitrogen from leaking.Caulking gum 10 is the stem portion 12 that contacted by the inner peripheral surface with container for storing liquid conduit 2 and cat head conduit 3; Be formed on the top of stem portion 12 and inner and at outstanding can being constituted of forming of its circumference of upper end edge of stem portion 12 by the top 11 that block container for storing liquid conduit 2 and cat head conduit 3 upper ends in order to prevent that caulking gum 10 is inserted into container for storing liquid conduit 2 and cat head conduit 3 fully.For to the inside of compressor nitrogen injection, in cat head conduit 3 and container for storing liquid conduit 2, insert caulking gum 10, then gas is injected pin and be inserted on the caulking gum 10 injecting gas then.But, because the surperficial smoother of the caulking gum 10 of this prior art, and the inwall of container for storing liquid conduit 2 and cat head conduit 3 also can become smooth because of oil remaining in the oiling process, causes when injecting gas that like this internal pressure the problem that caulking gum 10 outwards comes off can occur when rising.
Summary of the invention
In order to address the above problem, the object of the invention is to provide caulking gum and the manufacture method thereof that prevents gas leakage in a kind of difficult drop-off and the stopping property good compression machine.
In order to achieve the above object, the caulking gum that prevents gas leakage in the compressor provided by the invention comprises that the upper end of the container for storing liquid conduit that is inserted in compressor or cat head conduit contacts with gas leakage prevention and with the inwall of container for storing liquid conduit or cat head conduit and has the stem portion of rough external surface; With the upper end edge of stem portion its circumferential outside the outstanding top that forms.
The caulking gum manufacture method that prevents gas leakage in the compressor provided by the invention comprises that making can prevent electrical treating so that it has the stage of the mould of uneven surface with the periphery of in type stem portion; With the stage of using mould to carry out moulding.
The caulking gum difficult drop-off and the stopping property that prevent gas leakage in the compressor provided by the invention are good, and its manufacture method is simple.
Description of drawings
Be elaborated to preventing the caulking gum of gas leakage and manufacture method thereof in the compressor of the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the compressor arrangement synoptic diagram of prior art.
Fig. 2 is the caulking gum stereographic map among Fig. 1.
Fig. 3 is the caulking gum stereographic map that prevents gas leakage of the present invention.
Fig. 4 is the caulking gum leakiness test chart of prior art.
Fig. 5 is a caulking gum leakiness test chart of the present invention.
Embodiment
In the present invention, identical with the caulking gum of prior art structure is used identical symbol.Fig. 3 is the caulking gum stereographic map that prevents gas leakage of the present invention.As shown in Figure 3, the caulking gum 110 that prevents gas leakage in the compressor of the present invention by with the contacted stem portion 121 of the inwall of container for storing liquid conduit 2 and cat head conduit 3; With for prevent caulking gum 110 be inserted into fully container for storing liquid conduit 2 and cat head conduit 3 inside and at its outstanding can being constituted of forming outside circumferential of the upper end edge of stem portion 121 by the top 111 that block container for storing liquid conduit 2 and cat head conduit 3 upper ends.And stem portion 121 peripherys have passed through roughened surface treatment.The caulking gum manufacture method that prevents gas leakage in the compressor of the present invention comprises that making can prevent electrical treating so that it has the stage of the mould of uneven surface with the periphery of in type stem portion 121; With the stage of using mould to carry out moulding.The method of moulding can be used injection molding method or compressed moulding method, and the forming method difference, and the making method of mould is also different.For to the inside of compressor nitrogen injection, in cat head conduit 3 and container for storing liquid conduit 2, insert caulking gum 110, then gas is injected pin and be inserted on the caulking gum 110 injecting gas then.When gas was injected into to a certain degree, the compressor pressure inside will rise.But, because the periphery of caulking gum 110 of the present invention is more coarse, its inwall with cat head conduit 3 and container for storing liquid conduit 2 is tightly combined, thereby can prevent that caulking gum 110 from outwards coming off and improved sealing effectiveness.
Fig. 4 is the caulking gum leakiness test chart of prior art.Fig. 5 is a caulking gum leakiness test chart of the present invention.Above-mentioned chart is the result that 8 caulking gums are tested, and the data representation leakiness in the chart on the transverse axis, histogrammic height are represented corresponding caulking gum numeral, and vertical dotted line USL then is a higher limit, and this value is 0.2.As can be seen from Figure 4, the caulking gum of prior art is most to surpass higher limit, and as can be seen from Figure 5, caulking gum of the present invention does not all surpass higher limit.And the Ppk value of the caulking gum of prior art has only 0.13, and caulking gum of the present invention is 13.72, and its anti-leak result is very obvious as can be seen from these data.At this moment, Ppk uses is unit in the statistical method, and it is for showing the index of chronicity quality ability, and generalized case is issued to just thinks the stable level that reaches more than 4.5.
