Description
Technical field
The utility model relates to pipe joint technical field, particularly a kind of bellows gas range connector.
Background technique
Gas range is kitchen tools product comparatively common in the modern life, by people, is known.Gas range need to be connected with gas cylinder by pipeline when installing and using, and traditional rubber pipe is owing to being prone to deterioration phenomenon after long-time use, therefore existing gas range adopts bellows that connection is installed conventionally.Bellows need to be connected with kitchen range by means of special connector when connecting.The connector occurring in the market, its structure generally include fittings body, the union being flexibly connected with fittings body and with the gland nut of union screw-thread fit, the end of described fittings body is provided with path connecting tube, union is movably set on described path connecting tube, the end moulding of path connecting tube is provided with flange, is arranged with the Sealing coordinating with flange in described gland nut.During connection, path connecting tube is inserted in gland nut, and rotates union, gland nut and union screw thread are compressed, under the mating reaction of union and gland nut, Sealing and flange laminating, thus reach the effect being tightly connected.Yet, the defect of above-mentioned connector is: first, because seal configuration arranges unreasonable, make its deformation range limited, when the bellows kitchen range of above-mentioned connector and different manufacturers production or different size standard are connected, easily cause the not closely generation of phenomenon of connection, cause the versatility of this connector lower, easily there is gas leakage, strengthened security risk; The second, during compression, union, directly by flange squeeze sealing member, easily causes seal loading inhomogeneous, and connection sealing reduces.
For this reason, the applicant in April, 2014 11Xiang State Intellectual Property Office to have submitted application number to be 201420177076.7, patent name is the patent application of " a kind of bellows gas range connector ", its structure comprises fittings body, the union on fittings body is located in activity, and with the gland nut of union screw-thread fit, the end moulding of described fittings body is provided with path connecting tube, union is movably set on described path connecting tube, the end moulding of path connecting tube is provided with flange, in described gland nut, be arranged with the Sealing coordinating with flange, described Sealing connects and composes side by side by two identical seal rings are integrated, one end periphery of described Sealing is provided with first conical surface with flange laminating, the other end periphery of Sealing is provided with second conical surface being symmetrical set with first conical surface, on described path connecting tube, be also arranged with front-slider, described front-slider activity is located between union and flange, one end of described front-slider is provided with the first plane with union close fit, the other end of front-slider is provided with the having three pyramidal faces with flange close fit, between described gland nut and Sealing, be movably equipped with rear slider, one end of described rear slider is provided with the 4th conical surface with the second conical surface close fit, the other end of rear slider is provided with the second plane with gland nut end face close fit.By arranging by two integrated Sealings that connect and compose side by side of identical seal ring, deformation range is larger, when itself and union are connected, be convenient to the abundant close contact of union and gland nut, this connector can be connected with the bellows kitchen range of different size standard, effectively improve the versatility of connector; In addition, due to front-slider being set, avoid union directly to contact with flange, made seal loading more balanced, guaranteed the tightness that the utility model connects, effectively prevented the generation of gas leakage phenomenon.
Yet, also there are some defects in above-mentioned " a kind of bellows gas range connector ": first in actual use, because needs arrange union, path connecting tube, flange and front-slider, cause structure setting comparatively complicated, cause manufacture cost relatively high, and in course of working, easily cause the waste of material; The second, owing to arranging in order to union and front-slider are carried out to spacing flange, when flange while there is deformation, easily causes union and front-slider to occur obscission because of stressed, cause using comparatively inconvenience on path connecting tube; The 3rd, because flange directly contacts with Sealing, and flange is generally laminar that stainless steel material makes, and when wearing and tearing appear in the end face contacting with Sealing on flange, causes sealing greatly to reduce, and has affected the working life of product.
