The utility model adopts the technical solution that the pipe joint comprises a fastener comprising a fastener plate and fastener hooks, wherein the fastener hooks are respectively arranged on two ends of the lower surface of the fastener plate, the opposite surfaces of the two fastener hooks are relatively inclined, and are in an opening-gathering ditch shape with a metal plate, a flexible sealing piece is covered on the upper surface of the fastener plate, two lateral edges of the sealing piece are connected with a sealing flange which is downwards and inwards bent, and the sealing flange is inserted under the lower surface of the fastener plate, the outside of the seal piece is fastened by a locking clamp, two ends of the clamp are provided with mounting seats, bolt holes are arranged on the mounting seats, and securing members are spirally connected in the bolt holes. The pipe joint has the advantages of convenient construction, high use security performance, no corrosion stress, excellent sealing property and the like.
Description
Technical field
The utility model relates to a kind of pipe joint, especially a kind of pipe joint that is applicable to the pipe-line system of transporting water and vapour.
Background technique
Along with development of science and technology, the application of pipe-line system is wider.Existing pipeline connecting mode generally has clamp band type connection, FERRULETYPE connection, bayonet joint, welding type to connect and be connected or the like with flange-type.The clamp band type Placement, the pipe end that connects in advance groove processing form two kinds, a kind of is that thick-wall tube is machined, and must process in producer, another kind is the extrusion modling groove, and there is stress in processing connecting tube later, and has the hidden danger of stress corrosion; FERRULETYPE connects, and needs certain installing space, connects tube wall thickness and also needs the thickness that reaches certain; The bayonet joint mode is connecting also machine shaping in advance of pipe end; Welding type connects, and must weld at the scene that (be commonly called as in project installation and get angry, getting angry exists potential safety hazard, and inconvenience is installed, so reality is to avoid in installing as far as possible.), the weldability of tubing is required height, welding process can produce residual stress, and postwelding forms and is rigidly connected, and the tubing flexible compensation performance that temperature variation is produced is low, and is all restricted to the field welding construction space; Flange-type connects, require high to the butt joint assembly precision, and to on-the-spot pipe end welding requirements height, space religion shared in the time of need reserving spanner work when flange connects is big, having to strengthen pipeline spacing and pipeline takes up space, this connection belongs to and is rigidly connected, and is difficult for keeping sealing under the working environment of long-term vibration.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of easy construction, usage safety performance height is provided, does not have the pipe joint of stress corrosion, good seal performance.
The technological scheme that provides according to the utility model, described pipe joint comprises the fastener by fastener plate and fastener hook-forming, respectively establish the fastener hook at fastener plate lower surface two ends, the opposing side relative tilt of two fastener hooks, it and sheet metal are the ditch type that opening draws in, on fastener plate upper surface, be coated with flexible sealing fin, the both sides of the edge of diaphragm seal connect downwards and the sealing flange that bends inwards, described sealing flange inserts fastener plate lower surface below, diaphragm seal is fastening by the locking clip outward, two ends at clip have fitting seat, offer bolt hole on fitting seat, and fastening piece is spirally connected in bolt hole.
Outer surface two ends at the locking clip have circumferential fin.
The utlity model has easy construction, usage safety performance height, do not have advantages such as stress corrosion and good seal performance.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is the locking yoke configurations schematic representation in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: described pipe joint comprises the fastener 1 that is formed by fastener plate 11 and fastener hook 12, respectively establish fastener hook 12 at fastener plate 11 lower surface two ends, the opposing side relative tilt of two fastener hooks 12, it and sheet metal are the ditch type that opening draws in, on fastener plate 11 upper surfaces, be coated with flexible sealing fin 2, the both sides of the edge of diaphragm seal 2 connect downwards and the sealing flange 21 that bends inwards, described sealing flange 21 inserts fastener plate 11 lower surfaces below, diaphragm seal 2 is outer fastening by locking clip 3, has fitting seat 31 at the two ends of clip 3, offer bolt hole 32 on fitting seat 31, fastening piece is spirally connected in bolt hole 32.
Outer surface two ends at locking clip 3 have circumferential fin 32.
Fastener 1 is shaped as certain thickness and has the metal fastener plate 11 of two fastener hooks 12, two fastener hook 12 opposing side relative tilts, be the ditch type that opening draws in metal fastener plate 11, effect is that two sections porose connecting tubes 4 have been hooked the drawing effect, the effect of the design of plane of inclination in order to prevent that fastener 1 from coming off, diaphragm seal 2 Manufacturing material if intensity reach requirement and with is connected that tubing does not produce that potential difference is corroded and can; Diaphragm seal 2 is for bending to U type seal stock, and the selection of material decides according to factors such as fed sheet of a media temperature, and diaphragm seal 2 material selections are relevant according to the pipeline fed sheet of a media; Locking clip 3 by two lobes or three lobes semi-circular have bolt hole 31, the similar thimble connector of shape forms, two lobes or three lobes locking clip 3 close up that afterwards minimum diameter is more bigger than connecting tube 4 external diameters, it mainly acts on is to wale diaphragm seal 2; Fastening piece is made up of bolt, pad, nut, act as locking two halves locking clip 3.
Connecting tube 4 ends of before installation needs being installed utilize special-purpose drilling tool to punch in the relevant position, the punching number of locations according to the material wall thickness experiment with computing decide.Earlier diaphragm seal 2 is put an end of connecting tube 4 ends then, certain slit is stayed to alignment centre, hole in another section connecting tube 4 holes, this time image is equally buckled two sections connecting tubes with fastener 1 with stapling together, and then diaphragm seal 2 is moved to encase fastener 1 and tighten locking clip 3.
Claims (2)
1, a kind of pipe joint, comprise the fastener (1) that forms by fastener plate (11) and fastener hook (12), it is characterized in that: respectively establish fastener hook (12) at fastener plate (11) lower surface two ends, the opposing side relative tilt of two fastener hooks (12), it and sheet metal are the ditch type that opening draws in, on fastener plate (11) upper surface, be coated with flexible sealing fin (2), the both sides of the edge of diaphragm seal (2) connect downwards and the sealing flange (21) that bends inwards, described sealing flange (21) inserts fastener plate (11) lower surface below, diaphragm seal (2) is outer fastening by locking clip (3), has fitting seat (31) at the two ends of clip (3), offer bolt hole (32) on fitting seat (31), fastening piece is spirally connected in bolt hole (32).
