Description
Technical field
the present invention relates to metal bellow, specifically a kind of for field erected fuel gas transmission stainless steel ripple hose connection device.
Background technique
because the latus rectum of shallow ring metal bellows is large, pressure-bearing is high, heat-resisting, flexible, corrosion-resistant, long service life, and being widely used in the multiple pipelines such as room inlet pipeline, fuel gas pipeline, solar water heater water transport pipeline, fire main.Metal bellows used is at present generally the finished product of various different length, for choice for use during installation, is difficult to determine in advance, often needs the bellows bringing different lengths specification owing to needing the length of bellows during in-site installation.Along with the raising of bellows manufacturing technology, the domestic bellows having produced 300 meters long, if realize on-site cutting and guarantee bellows and other pipe fitting convenient and fast connection and safe and reliable, fixed will greatly expand the use field of metal bellows.China national intellectual property website disclose a kind of for field erected metal bellows, comprise body and cover nut thereon, the end of described body forms a boss, the external diameter of boss is greater than the aperture of nut inner hole, and the body wave trough place be positioned at inside boss clamps an annular opening metal gasket.When metal bellows is connected with other bodys, be provided with convenient and swift, that cost is low advantage, but its join strength is relatively low, when body when pulled, the easy overstress of bellows body and nut attachment portion, its sealing reduce, and produce gas leakage etc., thus the Security reduced when corrugated flexible hose uses and working life, the external diameter of corrugated flexible hose generally needs little more than 2mm than the internal diameter of pipe thread in addition, limits its using scope.
Summary of the invention
technical problem to be solved by this invention is the defect overcoming above-mentioned prior art, there is provided a kind of for field erected fuel gas transmission stainless steel ripple hose connection device, there is sealing high, can use at larger corrugated flexible hose external diameter (about 1mm less of the internal diameter of pipe thread), and install convenient, axial tensile strength is large, guarantees the advantage of safety reliability when connecting.
the present invention adopts following technological scheme: a kind of fuel gas transmission stainless steel ripple hose connection device, comprise corrugated flexible hose and cover plastic sheath thereon, the inwall of described plastic sheath is evenly distributed with some gas guide grooves, the outer cover of described plastic sheath is provided with a straight-through seat, seal ring is provided with between one end of described straight-through seat and plastic sheath, the other end inner circle of straight-through seat is provided with screw thread, the bottom of screw thread is provided with tool withdrawal groove, described screw thread is provided with 4 grooves (8), described tool withdrawal groove side is provided with clamping ring, wherein clamping ring is the eyelet that two halves separate, the inner circle of clamping ring is provided with groove, the corrugated appearance of groove and corrugated flexible hose matches, the cylindrical of clamping ring is provided with 4 boss, boss enters the tool withdrawal groove of thread bottom by 4 grooves at the screw thread place in straight-through seat, the side of described clamping ring is provided with sealing gasket.
the present invention has following beneficial effect: fuel gas transmission stainless steel ripple hose connection device have employed straight-through stand structure, facilitates installation; Tool withdrawal groove in straight-through seat and clamping ring structure add the intensity of section, and the axial tensile strength of body is improved greatly; The sealing gasket mechanism of the seal ring structure between plastic sheath and straight-through seat and clamping ring side, adds the sealing of fuel gas transmission corrugated flexible hose; The cylindrical being provided with 4 grooves and clamping ring by screw thread is provided with the structural design of 4 boss, has saved inner space, has made the corrugated flexible hose of larger external diameter can adopt the pipe thread of standard.
as preferably, the gas guide groove quantity of the inwall of described plastic sheath is 40-80.
further, described straight-through seat is provided with Leak hole, and cause gas leakage when corrugated flexible hose breakage, then the combustion gas of leaking flows to the straight-through of two ends along the gas guide groove in plastic sheath, discharges from Leak hole.
further, the screw thread of straight-through seat one end is pipe thread, can the link of direct connecting tube screw thread.
further, the cylindrical of described sealing gasket is provided with thin type packing ring, and the external diameter of thin type packing ring is greater than the internal diameter of tool withdrawal groove.The inwall of this thin type packing ring and tool withdrawal groove compresses and produces and seal, and the combustion gas of Leakage prevention leaks from thread gap, prevent simultaneously outside water or corrosive material enter straight-through in the straight-through usability of impact.
