Abstract
The utility model discloses a hose coupling and aims at providing the hose coupling which is good in sealing performance and can be connected with hoses stably. The hose coupling comprises a coupling tube body, wherein two ends of the coupling tube body are communicated. The front portion of the coupling tube body is a sleeve connecting end which is used for connecting with the hose. A circular stop ring is arranged on the rear portion of the sleeve connecting end. An inner ring of the stop ring bends towards the sleeve connecting end to form a welding end. The stop ring is fixed with the surface of the coupling tube body through the upper surface or the lower surface of the welding end in a welded mode. A plurality of ringlike sliding resistant fringes are arranged on the surface of the sleeve connecting end.
Description
Technical field
The utility model relates to a kind of hose connection device, especially relates to a kind of hose coupling.
Background technique
Make the field in modern production, have more manufacturing mechanism with liquid or gas as working medium, or carry out heat exchange etc. with liquid or gas, at this moment just need the use flexible pipe that the corresponding site of equipment is connected to carry liquid or gas.Usually need between flexible pipe and the equipment to use hose coupling to connect.
Chinese patent notice of authorization number: CN 200520013123.5, May 16 2007 notice of authorization day, a kind of hose coupling is disclosed, it includes a metallic hose and the coupling nut that is socketed on the hose coupling, described flexible pipe connecting end is fixed with a rubber and plastic interface, and coupling nut is socketed in the inboard of rubber and plastic interface; Described rubber and plastic interface Integral mold is molded in the inner orifice of flexible pipe connecting end; This model utility compared with prior art has simple in structurely, easy to use, and preparation process is simple, the advantage that cost is low.But also Shortcomings part of this model utility simultaneously, flexible pipe gets loose from hose coupling easily, has brought quality and potential safety hazard, adopts locking device then to improve cost of production, and also comparatively inconvenience of installation process, has reduced manufacturing efficiency.
The model utility content
The utility model is in order to overcome the deficiency that flexible pipe goes out to get loose from hose coupling easily in the prior art, and preferably hose coupling of stable connection and sealing is provided between a kind of flexible pipe and the hose coupling.
To achieve these goals, the utility model is by the following technical solutions:
A kind of hose coupling of the present utility model, comprise the joint body that two ends connect, described joint body is anterior for being used for the socket end of connecting hose, described socket end rear portion is provided with the back-up ring of annular, the interior hoop socket end bending of described back-up ring forms welding ends, described back-up ring is fixed by the surface soldered of welding ends upper surface or lower surface and joint body, and described socket end surfaces is provided with the anti-skidding striped of some ring-types.At the socket end surfaces anti-skidding striped is set, the surface friction drag that hose proof is subject to after being socketed on the end is larger, is difficult for sliding at the socket end, can guarantee stable connection between flexible pipe and the hose coupling.The back-up ring one of annular plays position-limiting action in the face of flexible pipe, provides attachment face for packing ring is installed on the another side, is conducive to improve the sealing of hose coupling.After the individual pen bending, for back-up ring can be smoothly and hose coupling weld face of weld or seam be provided, the area of contact that ring bends between rear and the joint body in the back-up ring simultaneously increases, and the situations such as swing appear in anti-Sealing shield ring, is convenient to the location between back-up ring and the joint body when welding.
As preferably, described hose coupling vertically is provided with weld seam along the joint body.With respect to stainless steel pipe, the joint body adopts corrosion resistant plate to be welded after twisting, and cost is lower like this, and relative and tubing can only corresponding a kind of calibers simultaneously, use steel plate can conveniently control to reach the purpose of producing different tube diameters joint body, its versatility and adaptability are larger.
As preferably, the rear end of described joint body forms ear end face to the external side bending of adaptor tube, is formed for the gasket groove of retaining washer between described back-up ring and the ear end face.Packing ring is installed in the gasket groove, keeps fixing with hose coupling, and the workman is when mounting and dismounting, and packing ring can not drop, and avoids making troubles to the workman, has improved working efficiency.
As preferably, the tapered or circular arc of described anti-skidding striped.Flexible pipe is comparatively smooth when being inserted in the socket end like this, and larger resistance is still then arranged when flexible pipe produces the trend of separating with the socket end between the two, therefore can further strengthen fixing for flexible pipe.
As preferably, described joint body adopts stainless steel to make; As preferably, described back-up ring adopts stainless steel to make.The brass material that adopts compared on the market hose coupling, greatly saved cost of production after adopting stainless steel, stainless intensity and anti-corrosion capacity are also stronger, be conducive to improve its working life, and the relative brass of the stainless capacity of heat transmission is relatively poor, hose coupling can have preferably insulating power after adopting stainless steel, and thermal loss is less, plays energy-conserving action.
Therefore, the utlity model has following beneficial effect: (1) can prevent effectively that flexible pipe from separating with hose coupling, guarantees the reliability of connection, has simultaneously preferably sealing, exempts potential safety hazard; (2) adopt stainless steel to make, cost is lower, better performances.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 1 sectional view;
Fig. 3 is the utility model embodiment 2 sectional view.
Among the figure, joint body 1, socket end 1a, ear end face 1b, back-up ring 2, welding ends 2a, weld 3, weld seam 4.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment 1 as shown in Figure 1 and Figure 2, a kind of hose coupling comprises the joint body 1 that two ends connect, and joint body 1 adopts corrosion resistant plate to twist and forms, along the joint body longitudinally weld seam 4 by being welded and fixed.Joint body 1 is anterior for socket end 1a, is used for connecting hose.Socket end 1a surface is provided with the anti-skidding striped of ring-type, and anti-skidding striped is tapered, can prevent effectively that flexible pipe and socket end 1a break away from.Socket end 1a rear portion is provided with the back-up ring 2 of annular, and back-up ring 2 also adopts stainless steel to make.The interior hoop socket end 1a bending of back-up ring 2 forms welding ends 2a, welding ends 2a fixes near the side surface of ear end face 1b and the surface soldered of joint body 1, during welding, flow into the gap between welding ends 2a and joint body 1 surface after the copperwelding rod fusing, form weld 3 both are fixedly connected with.The rear end of joint body 1 forms ear end face 1b to 1 outside bending of joint body, forms gasket groove 1c between back-up ring 2 and the ear end face 1b, reaches preferably sealing thereby can put into packing ring in the gasket groove 1c.
