Abstract
The invention discloses a stainless steel corrugated hose connecting device for fuel gas transportation. The stainless steel corrugated hose connecting device for the fuel gas transportation comprises a corrugated hose and a plastic protective sleeve which is arranged on the corrugated hose in a sleeved mode. A plurality of gas-guiding grooves are evenly formed in the plastic protective sleeve. A straight through seat is arranged outside the plastic protective sleeve in a sleeved mode. A sealing ring is arranged between one end of the straight through seat and the plastic protective sleeve. Threads are formed in an inner circle of the other end of the straight through seat. A tool withdrawal groove is formed at the bottom of the threads. Four concave grooves are formed in the threads. A clamping ring is arranged on one side of the tool withdrawal groove, wherein the clamping ring is a metal ring which is divided into two pieces. A ditch groove is formed in an inner circle of the clamping ring. The ditch groove is matched with the corrugated appearance of the corrugated hose. Four bosses are arranged on an outer circle of the clamping ring. The bosses enter the tool withdrawal groove of the bottom of the threads through the four concave grooves, located at the place of the threads, of the straight through seat. A sealing mat is arranged on one side of the clamping ring. The stainless steel corrugated hose connecting device for the fuel gas transportation has the advantages of being convenient to install, high in axial tensile strength and good in sealing property. The stainless steel corrugated hose connecting device for the fuel gas transportation saves inner space and enables a corrugated hose with a larger outer diameter to be capable of adopting standard pipe threads.

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 generally the finished product of various different lengths at present, and choice for use during for installation needs the length of bellows to be difficult to determine in advance while installing due to scene, often need the bellows with upper different lengths specification.Along with the raising of bellows manufacturing technology, domesticly can produce 300 meters long bellowss, if realize on-site cutting and guarantee bellows and other pipe fitting convenient and fast connection and safe and reliable, surely will greatly expand the use field of metal bellows.On 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 that is positioned at the boss inboard clamps an annular opening metal gasket.When metal bellows is connected with other bodys, had advantages of convenient and swift, cost is low, but its join strength is relatively low, when body when pulled, bellows body and nut attachment portion easily stressed excessively, its sealing reduces, and generation gas leakage etc., thereby reduced Security and working life when corrugated flexible hose is used, more than the external diameter of corrugated flexible hose needs little 2mm than the internal diameter of pipe thread is general in addition, limited its using scope.
Summary of the invention
technical problem to be solved by this invention is the defect that overcomes above-mentioned prior art, providing a kind of carries with stainless steel ripple hose connection device for field erected combustion gas, there is sealing high, at larger corrugated flexible hose external diameter (than the little 1mm of the internal diameter of pipe thread left and right), can use, and install convenient, axial tensile strength is large, the advantage of the safety reliability while guaranteeing to connect.
the present invention adopts following technological scheme: a kind of combustion gas is carried with 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, be provided with seal ring 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 one 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 is complementary, 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, one side of described clamping ring is provided with sealing gasket.
the present invention has following beneficial effect: combustion gas is carried and has been adopted straight-through stand structure with stainless steel ripple hose connection device, has facilitated installation; The intensity that tool withdrawal groove in straight-through seat and clamping ring structure have increased section, make the axial tensile strength of body greatly improve; Seal ring structure between plastic sheath and straight-through seat and the sealing gasket mechanism of clamping ring one side, increased the sealing that corrugated flexible hose is carried in combustion gas; The cylindrical that is provided with 4 grooves and clamping ring by screw thread is provided with the structural design of 4 boss, has saved inner space, makes 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, when the corrugated flexible hose breakage, causes gas leakage, and the combustion gas of leaking flows to the straight-through of two ends along the gas guide groove in plastic sheath, from Leak hole, discharges.
further, the screw thread of straight-through seat one end is pipe thread, directly the link of connecting tube screw thread.
further, the cylindrical of described sealing gasket is provided with the 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 sealing, and the combustion gas of Leakage prevention leaks from thread gap, prevents that outside water or corrosive material from entering the straight-through usability of straight-through interior impact simultaneously.
