Description

Stainless steel joint for pipeline

The utility model relates to a kind of stainless steel joint for pipeline that reduces cost.

Home pipeline mainly is based on sebific duct before, yet sebific duct easily breaks, and corrosion-vulnerable, and cause the contaminated situation of potable water, so all be that sebific duct is used for releasing system at present, water supply system is then used iron pipe instead in addition, but iron pipe has easy oxidation and rusting and shortcoming such as perishable, therefore often causes water pollution issue, and because the iron pipe strength deficiency, therefore when building is in the milk, often cause the deviation of iron pipe, ferrous pipe structure is damaged, inconvenience arranged so be that water supply system is real with the iron pipe, and Stainless Steel Tube is owing to itself have non-corrosive, material behavior such as do not corrode, and can effectively improve the health of feedwater, and Stainless Steel Tube is because intensity own is enough, thus when being in the milk the problem of unlikely generation Stainless Steel Tube deviation, therefore if can use Stainless Steel Tube instead is supply pipe, will effectively improve the shortcoming and inconvenience of iron pipe.

Thought is before owing to the length of pipeline differs, and also need turn, so need carry out being connected in series of iron pipe, and the linkage structure of iron pipe before is as shown in Figure 5, iron pipe 50 two ends external diameters is cut with scissors dentification threaded end 51 respectively in the job site, and utilize an inner joint 60 that forms screw 61 to connect, mainly be on iron pipe 50 threaded end 51, to twine waterproof cloth 55 when it connects, then with both sides iron pipe 50 screw locks in connecting head 60 two ends, and reach the purpose that connects iron pipe 50; Yet above-mentioned mode also is not suitable on the Stainless Steel Tube, and its reason is as follows:

(1). cost is too high: when connecting owing to iron pipe, need form threaded end in two ends respectively, and break and the adhesive strength deficiency for fear of iron pipe, therefore iron pipe need keep certain thickness, and Stainless Steel Tube is expensive than the price of iron pipe, and the thick more pipe valency of Stainless Steel Tube is high more, therefore directly cuts with scissors out screw thread as desiring on Stainless Steel Tube, and invisible will increase high cost.

(2). construction inconvenience: because the toughness of material height of Stainless Steel Tube, no fragility, add often sticking cutter in man-hour, therefore be not easy to existing field boundary and directly carry out smear metal processing, as desire to process in the scene, then need to increase the time of processing, so as to be same as the linkage structure construction of iron pipe, the inconvenience that then will cause stainless steel to construct.

In view of this, this creator is the shortcoming and deeply discussion of inconvenience that can't be applicable to Stainless Steel Tube at traditional linkage structure, and actively seek the road of improvement, through long-term effort research and development, finally successfully create a kind of stainless steel joint for pipeline of being convenient to connect, use and reduce the cost that Stainless Steel Tube connects.

Therefore, the purpose of this utility model provides a kind of stainless joint of being convenient to construct, it mainly is to be formed with a reaming groove in a sleeve, and the Stainless Steel Tube end is formed with the taper flared end, and makes Stainless Steel Tube can pass sleeve, and clip is in the reaming groove, and sleeve one end is formed with a tapped hole, uses for screw lock on a connecting head, reaches the purpose that connects Stainless Steel Tube, and do not need in Stainless Steel Tube end hinge tooth, use the cost of Stainless Steel Tube with effective saving.

The technical solution of the utility model is to provide a kind of stainless steel joint for pipeline, and this joint is to be arranged with a sleeve in a Stainless Steel Tube end, and sleeve one end and locking have a connecting head,

Wherein Stainless Steel Tube is a Sheet Steel Pipe, and be formed with the flared end of a tapered opening shape in the Stainless Steel Tube end, be formed with a tapped hole for the connecting head screw lock again in the sleeve, and be formed with the clamping groove of a taper in the sleeve, wherein the tapering of clamping groove is identical with flared end, and make the aperture of different tapped hole one end of sleeve less

The connecting head two ends of hollow shape are formed with a threaded end respectively again, for the tapped hole screw lock of sleeve.

In above-mentioned stainless steel joint for pipeline, connecting head two threaded end two ends can outwards protrude out a convex ring edge respectively, can a sheathed Sealing on this two convex ring edge, and can press for the flared end ora terminalis of Stainless Steel Tube;

In addition, sleeve outer diameter can be prism-shaped, and the connecting head external diameter also can be corresponding prism-shaped, establishes screw lock for pulling folder.

The utility model compared with the prior art advantage and good effect is very obvious.By above technological scheme as can be known, with design of the present utility model, need not directly to cut with scissors out screw thread in the Stainless Steel Tube two ends, can utilize sleeve and connecting head to make it to link together, and can effectively reduce the thickness of Stainless Steel Tube, simultaneously because Stainless Steel Tube is not perishable, and strength ratio iron pipe height, therefore it not only can reduce thickness, and its processing precise degree height, overall weight is light, carries laborsaving, and the purpose that can reach easy construction and reduce cost has following advantage and use value simultaneously:

(1). easy construction: use the machining operation fast convenient, process time is short, and can process in advance in factory, and luggage is joined again to the building site, also can on-the-spot process, and pipe fitting is detachable, can repeat to install and use.

(2). clean hygiene: the Stainless Steel Tube corrosion resistance is good, does not have corrosion phenomenon, does not have the smear metal residue during therefore unlikely polluted water, and assembling, and can effectively hold the cleaning of pipe-line system.

(3). sturdy and durable: the utility model is made with stainless steel, so mechanical durability such as it is counter-bending, anti-vibration is good, causes tubular axis to tilt even suffer the external force extrusion and vibration, does not also have the phenomenon of seepage and disengaging.

(4). the economic benefit height: buildings in general all has the service life in 50 years, but the life-span of general iron pipe pipeline only had an appointment 20 years, thus need often substitute pipeline, and this real sheet is novel with Stainless Steel Tube for it, its life-span can be maintained to more than 50 years, so can avoid changing the puzzlement of pipeline.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
