Description
Technical field
The present invention relates to a kind of tube fitting for stainless steel tubing, especially a kind of assembling pipe joint for connecting stainless steel tube。
Background technology
In modern life plumbing and direct drinking pipe-line system, stainless steel pipe is most widely used pipe fitting, owing to stainless metallographic structure is sufficiently stable, corrosion-resistant, so being widely used in water delivery, the transfer pipeline of pipeline road and various fluid chemical material, its mounting means mainly has argon arc welding formula and clamp-press type, owing to argon arc welding requires higher solder technology, need factory is carried out long-term professional training, relative cost is higher, and clamp-press type needs bigger pressure when installing, and when different size pipe fitting is installed, need different Ka Yaqianzui, change relatively cumbersome。How designing a kind of easy for installation, installation effectiveness is high, and the reliable assembling pipe joint of stable connection is the problem needing to solve。
Summary of the invention
Inconvenience is connected in order to solve existing Petrochemical Pipe Joints, cost is high, installation difficulty, the technical problems such as disassembling, assembling and replacing trouble, the present invention provides a kind of assembling pipe joint for connecting stainless steel tube, realizes simple in construction, easy for installation, installation effectiveness is high, and stable connection is reliable, changes easy-to-disassemble and assemble effect。
The present invention solves that above-mentioned technical problem be the technical scheme is that a kind of assembling pipe joint for connecting stainless steel tube, including pipe joint, tube joint assembly and pipe connecting structure, tube joint assembly is made up of sealing ring mounting groove and sealing ring, pipe connecting structure is made up of the fixed part of screwed hole, screw and pipe joint outer wall, described pipe joint is provided with pipeline birdsmouth, at least one sealing ring mounting groove is set in described pipeline birdsmouth, in sealing ring mounting groove, is provided with sealing ring；The step for pipeline is axially positioned it is provided with in pipeline birdsmouth；Having the screwed hole for fixing stainless steel tube and screw on pipe joint outside, described screwed hole is positioned at the outside of sealing ring mounting groove。
The quantity of described sealing ring mounting groove is 6。
Described screw is hexagon socket countersunk flat cap head screw。
The quantity of described screwed hole is 2 to 8, is distributed in the outside of pipe joint。
Compared with prior art, the invention has the beneficial effects as follows: present tube connector exterior has at least one or more screwed hole for fastening body, stainless steel tube inserts inside pipe joint, it is connected to a fixed by external screw-thread, having abandoned traditional argon arc welding formula and clamp-press type mounting means, installing/dismounting is more convenient, simply, requiring without significantly high technology and expensive installation tool, common laborer gets final product smooth construction through simple training；Pipe joint can Reusability repeatedly, be hardly damaged, recyclable recycling, saved resource；Present tube adapter assembly is made up of sealing ring mounting groove and sealing ring, and sealing ring ensure that pipeline is connected firmly, and has excellent sealing。
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention；
Fig. 2 is inventive pipeline birdsmouth schematic diagram；
Labelling in figure: 1, pipe joint, 2, pipeline birdsmouth, 3, sealing ring mounting groove, 4, sealing ring, 5, screwed hole。
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail。
As shown in the figure, a kind of assembling pipe joint for connecting stainless steel tube, including pipe joint 1, tube joint assembly and pipe connecting structure, tube joint assembly is made up of sealing ring mounting groove 3 and sealing ring 4, pipe connecting structure is made up of the fixed part of screwed hole 5, screw and pipe joint 1 outer wall, described pipe joint 1 is provided with pipeline birdsmouth 2, is provided with at least one sealing ring mounting groove 3 in described pipeline birdsmouth 2, in sealing ring mounting groove 3, is provided with sealing ring 4；The step for pipeline is axially positioned it is provided with in pipeline birdsmouth 2；Having the screwed hole 5 for fixing stainless steel tube and screw on pipe joint 1 outside, described screwed hole is positioned at the outside of sealing ring mounting groove 3。
It is more than the basic embodiment of the present invention, further improvement can be done on above basis, improve and limit: the quantity of sealing ring mounting groove 3 is as 6 as mentioned。
It is more than the basic embodiment of the present invention, further improvement can be done on above basis, improve and limit: screw is as hexagon socket countersunk flat cap head screw as mentioned。
It is more than the basic embodiment of the present invention, further improvement can be done on above basis, improve and limit: the quantity of screwed hole 5 is as 2 to 8 as mentioned, is distributed in the outside of pipe joint 1。
During normal operation, the link of stainless steel tube is inserted into pipeline birdsmouth 2 place, and closely cooperates with the sealing ring 4 being placed in sealing ring mounting groove 3, the step for pipeline is axially positioned arranged in pipeline birdsmouth 2, can guarantee that the axial location of pipeline, it is prevented that the phenomenons such as deflection occur；Keeper and hexagon socket countersunk flat cap head screw, by screwed hole 5 precession, produce pulling force, make the fixed part of pipe joint 1 produce to closely cooperate with stainless steel pipes, can realize the compact siro spinning technology of pipeline。
Present configuration is simple, easy for installation, installation effectiveness is high, and stable connection is reliable, change easy disassembling, solving existing Petrochemical Pipe Joints and connect inconvenience, cost is high, installation difficulty, the technical problems such as disassembling, assembling and replacing trouble, for prior art, it is once great technological innovation, there is good market prospect and development space。
