Description
Technical field
Engineering element pipe fitting is the utility model is related to, particularly the card of one kind three pressure water purification thin-wall stainless steel pipe fitting.
Background technology
With the implementation of China's policies of reform and opening to the outside world, national economy obtains rapid growth, town-property, public building and trip
Trip facility is largely built, and new requirement is proposed to hot water supply and domestic water supply.Particularly quality problem, people are more next
More pay attention to, it is desired to also improve constantly.This common pipe materials of coating steel pipe are because of its susceptibility-to-corrosion, in the influence of national relevant policies
Under, the arena of history will be gradually backed out.Various novel plastics pipes and compound be in control develop rapidly, but the also different journeys of these tubing
Drinking water and relevant water quality are wanted far from the complete needs for adapting to water supply piping and country there is some shortcomings on degree ground
Ask.Therefore, relevant expert foretells:Building Supplies Water Pipe is finally restored to the epoch of metal tube.In order that drinking water is not because supplying
Water pipe material and promoted the use of thin-wall stainless steel as water supply line by secondary pollution, the portion of urban construction at present.Existing disclosed thin-walled
Stainless steel pipe has use even to be had sealing ring, the cylindrical loose joint screwing structure for having nut wire ring among steel tube head flange.This
Although class formation detachable maintaining is convenient, complicated, stainless steel materials are more, expensive, and cost is high, it is difficult to promotes the use of.
State Administration for Quality Supervision and Inspection and Quarantine's on July 10th, 2003 is formulated and has issued GB/T19228.1, GB/ in urban construction portion
T19228.2, GB/T19228.3 series standard, promote stainless steel clamp-press type pipe-line system.This clamp-press type pipe is simple in construction,
Cost is low, can be described as single deck tape-recorder pressure stainless steel pipe, but due to installing the sealing groove shape design problem of O-ring seals, its annular
It is unlikely to deform during the card pressure of convex portion, O-shaped rubber ring can not be in close contact and hold tightly with tube wall, therefore sealing is poor, holds resistance to force down.
Chinese patent discloses a kind of squash type pipe and connect (ZL00251669).Although it also form when being pressed with specific purpose tool card
Double card pressure enhancing sealing, but this pipe joint connect steel pipe two between excessively stream latus rectum it is variant, larger water resistance, and water can be produced
Medium and small slag is easily deposited at this, is produced corrosion, is influenceed water quality.And connector endoporus does not set the positioning step for steel pipe insertion,
Determine to be limited with making pipe-line system installation dimension position, influence installation process.And Chinese patent ZL03249515.3 practicalities are new
Type patent also discloses that a kind of double jam-on stainless steel pipe fittings, including the pipe joint body provided with symmetrical convex portion, is set in the convex portion
There is sealing ring, this mechanism easily causes sealing ring connecting tube and poked when mounted, so as to cause sealing effectiveness poor.Manage simultaneously
Part connection end only sets one of tongue connection, it is impossible to bears larger pressure.And installation card pressure is big, the loss to instrument is big,
So as to also reduce the service life of card pressure instrument.

Referring to figs. 1 to Fig. 7, one kind three as shown in Figure 1 card pressure water purification thin-wall stainless steel pipe fitting, the three cards pressure water purification thin-walled
Stainless steel pipe has connector 1, and the end of bell and spigot 4 of connector 1 is all provided with least twice annular protrusion 2, is provided with annular protrusion 2
Unique inside groove 10, inside groove 10 are built-in with the fixing ring 3 that shape is engaged with inside groove 10.It is provided with and quilt in connector 1
The positioning step 5 that even steel tube head is engaged, buffering area is provided between adjacent two annular protrusion 2 of each bell and spigot 4
9, the turning of the non-inserting section 8 in connector 1 forms the swollen type of orthodrome by water swelling method and crosses bridge section 7.
Preferably, annular protrusion 2 is three.
Preferably, annular protrusion 2 is four.
The annular protrusion 2 can also be more than four.
As shown in Fig. 1, Fig. 6 and Fig. 7, the three cards pressure water purification thin-wall stainless steel pipe fitting, the shape of cross section of its annular protrusion 2
For D types outer ring, inside groove 10 is trapezoidal groove, and trapezoidal groove is sealed using fixing ring 3, wherein, and the material of fixing ring 3
Material can use chlorinated scoline, ethylene propylene diene rubber or nitrile rubber according to the property of institute's trandfer fluid.
The connector 1 can also be two logical or threeway or four-way and bend pipe, reducing joint pipe fittings, and the number of bell and spigot 4 is by upper
State two logical or threeways or four-way and bend pipe, reducing joint pipe fitting determine.
Understand in summary, the utility model has the following advantages that：
As shown in Figure 1, Figure 2 and Figure 4, designed, ensured using the seal construction of multiple tracks annular protrusion 2 and fixing ring 3
Better seal performance, avoids the corners such as elbow, threeway hidden danger is leaked caused by angular distortion.It it also avoid because of pipe
Road is oversize to cause pipeline to deform leakage problem with pipe fitting, can bear high pressure.
As shown in Figure 1, Figure 2 and Figure 4, annular protrusion 2 is using D types outer ring, and inside groove 10 is trapezoidal groove, and edge sealing fillet is set
Meter, curved surface coordinate.It can preferably hold tightly and seal with pipe, filling is full, and fixing ring 3 is fully sealed in trapezoidal groove,
It can not be extruded away.In pipeline bending, vibrate, rotation, when angle tilt will not leak, avoid because of sealing ring
With main body coordinate it is bad and caused by leakage phenomenon.
