Abstract
The utility model discloses a quick coupler of a flexible metal tube for conveying gas and liquid, comprising a coupler body, a sealing ring and the flexible metal tube, wherein the coupler body is provided with an insertion hole in which the flexible metal tube can be inserted from back to front; the groove-shaped sealing ring, a screwed fastener and a tightening clamp sleeve are sequentially arranged in the insertion hole; the front half part of the coupler body is provided with a screw thread corresponding to a corrugated metal tube; the sealing ring is of a circular groove shape; and the flexible metal tube is a corrugated tube and the outermost layer of the flexible metal tube is provided with a protective sleeve. Compared with the prior art, the corrugated flexible metal tube can be connected to the coupler by hands without external tools, the components are less, the installation is convenient and rapid, the sealing effect is good and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of rapid pipe joint, particularly a kind of rapid pipe joint that is used to carry the metallic hose of gas-liquid.
Background technique
The mode of traditional gas appliances such as connection LP gas cylinder, fuel tube or gas cooker is to tighten with Drop-proof with galvanized wire through the rubber pipe connection and at the two ends of rubber pipe; This Placement exists many defectives: install and transposing inconvenience; Under bending state, block gas circuit easily; The rubber pipe corrosion-resistant, be prone to aging, working life is short, and gas leak phenomenon takes place easily, the leakage that can cause various coal gas, combustion gas thus causes accident to take place.For solving the safe and reliable connectivity problem of gas pipeline; It is main body that corrugated metal pipe is adopted in domestic appearance in succession; Have certain flexible flexiblely and can not bend, it is convenient and reliable to be threaded, and can thoroughly stop gas leakage, choke phenomenon; Thereby reduced the generation of gas leakage accident to a great extent, actual effect is fine.The joint part of the combustion gas end of using has at present also adopted supporting with it inipple device, but its component are more and less, inconvenient installation, will have very big potential safety hazard in case lacked certain component.
The model utility content
The utility model technical problem to be solved is a kind of rapid pipe joint that is used for connecting the metallic hose that is used to carry gas-liquid that provides to above-mentioned existing technology present situation.
For solving its technical problem, the technological scheme that the utility model adopted is: a kind of rapid pipe joint that is used to carry the metallic hose of gas-liquid comprises joint body, metallic hose; Said joint body has one can hold the jack that metallic hose inserts from back to front; In this jack, be disposed with seal ring, spiral fastener; Tighten up cutting ferrule; Said joint body front half part is provided with and the corresponding spiral lamination of said metallic hose, and said seal ring is a ring groove shape, and said metallic hose is that bellows and outermost surface are provided with the protecting jacket that the macromolecule active material is processed.
As preferably, said metallic hose screws in the said joint body.
As preferably, said spiral fastener makes its underpart through the mode of screwing compressing sealing element to metallic hose tighten, spacing.
As preferably, the said cutting ferrule that tightens up seals metallic hose through the mode of screwing and fixes.
The beneficial effect of the utility model is: a kind of rapid pipe joint that is used to carry the metallic hose of gas-liquid that relates in the utility model; Be to utilize joint body that corrugated metal pipe is spun; The groove shaped seal ring seals its front end, spiral fastener with tighten up cutting ferrule and carry out spacing, fixing and sealing corrugated metal pipe.Because the less packaging technology that makes of component is simplified more, and sealing effect and join strength after the assembling obviously strengthen.
Description of drawings
Fig. 1 is the hose coupling structure schematic representation of the utility model;
Fig. 2 is the plan view of groove shaped seal ring;
Fig. 3 is the schematic representation that tightens up cutting ferrule;
Among Fig. 1 the sequence number of marking explanation as follows: the 1-joint body, 2-groove shaped seal ring, the 3-metallic hose, the 4-compressing sealing element, the 5-spiral fastener, 6-tightens up cutting ferrule, the 7-protecting jacket.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.Referring to shown in Figure 1, for a kind of rapid pipe joint that is used to carry the metallic hose of gas-liquid, include a joint body, it has one can hold the jack that corrugated flexible metal tube inserts from back to front.In this jack, be disposed with groove shaped seal ring 2, spiral fastener 5 tightens up cutting ferrule 6.Wherein the groove shaped seal ring is arranged on bottom in the joint body 1, closely contacts with the groove shaped seal ring 2 of bottom when said corrugated flexible metal tube 3 screws in the joint bodies 1 and its head is sealed in the groove seal ring 2 fully, the sealing effect reinforcement.Said metallic hose 3 is provided with the protecting jacket 7 that the macromolecule active material is processed for bellows and outermost surface.Be arranged on the spiral fastener 5 on joint body 1 outside boss, said spiral fastener 5 through the mode of screwing make 4 pairs of corrugated flexible metal tubes 3 of compressing sealing element of its underpart tighten, spacing.Said joint body rearward end is provided with one and tightens up cutting ferrule 6, said corrugated flexible metal tube 3 is sealed and fixes through the mode of screwing.
