The specific embodiment
See also Fig. 1 to Fig. 3, Fig. 1 to Fig. 3 is the structural representation of fire hydrant of the present invention.Comprise fire hydrant body 5, be provided with two delivery ports 51 on described fire hydrant body, certainly, this delivery port also can only be established one, is provided with groove 12 on the lateral surface of the water inlet end 11 of described fire hydrant body 5.This fire hydrant earlier is provided with first Baltimore groove 12, in use at water inlet pipe 2 and preparation and fire hydrant coupling part arranged outside second Baltimore groove 22 on the lateral surface of the water inlet end of fire hydrant 5.Then, sealing ring 3 (rubber ring) is enclosed between first Baltimore groove 12 and second Baltimore groove 22 of fire hydrant 5, at last, load onto anchor ear 4 at described sealing ring 3, described anchor ear 4 is to be formed by connecting with screw rod by two and half hoops, allow the button bit 41 (being clasp in the present embodiment) at anchor ear 4 two ends be stuck in first Baltimore groove 12 and second Baltimore groove 22, with screw rod 42 and nut 43 two and half hoops are locked, anchor ear 4 compresses sealing ring 3 just passable.
The fire hydrant of this connection has the installation and removal of being easy to, the also manipulable advantage of layman.
The present invention also can be used for the connection between the pipeline, describe the method for attachment that the present invention is used for pipeline in conjunction with Fig. 4 in detail with the connection of metal tube, among Fig. 4,, can realize as follows if first pipe 1 and water inlet pipe 2 that external diameter is equated couple together:
(1), adopt the method for cutting, on the lateral surface of the blank area 11 of first pipe 1, process first Baltimore groove 12;
(2), equally adopt the method for cutting, on 21 minutes the lateral surface of connector portions of water inlet pipe 2, process second Baltimore groove 22;
(3), put sealing ring 3, the sealing circle is a rubber seal, and the internal diameter of described sealing ring 3 equals the external diameter of first pipe 1 at the blank area 11 of first pipe 1; Certainly, this step also can be earlier puts sealing ring 3 with the blank area 21 of water inlet pipe 2.
(4), the blank area 21 of water inlet pipe 2 is inserted in the described sealing ring 3, and the opposite face of first pipe 1 and water inlet pipe 2 is adjacent to; Put in the sealing ring 3 if previous step is first blank area 21 with water inlet pipe 2, then this step should be in the described sealing ring 3 of blank area 11 insertions of first pipe 1.
(5), device anchor ear 4 outside described sealing ring 3, make the inwall of described anchor ear 4 compress described sealing ring 3, liquid in preventing to manage or gas are revealed, and the button bit 41 that makes described anchor ear 4 bending inwards of two ends and form is stuck in described first Baltimore groove 12 and second Baltimore groove 22, can not break away from axially producing displacement to guarantee first pipe 1 and water inlet pipe 1.
Described first Baltimore groove 12 and second Baltimore groove 22 among Fig. 4 are continuous cannelures, in fact, described first Baltimore groove 12 and second Baltimore groove 22 also can adopt the interruption groove structure, promptly in above-mentioned continuous cannelure, whenever the partition that keeps at a certain distance away forms concave point one by one.At this moment, the shape of described button bit 41 also will be made the structure of sawtooth like shape, and is corresponding with a concave point with each sawtooth, and generally speaking, as long as anchor ear 4 can screens first pipe 1 and water inlet pipe 2, the structure that does not allow both break away from all is fine.
See also Fig. 5, Fig. 5 is the sectional structure schematic diagram that the present invention is used for the another kind of embodiment of pipe connection.Embodiment illustrated in fig. 5 and embodiment illustrated in fig. 4 comparing, its general structure is identical, and different is that described first location division is first bulge loop 13.Described second location division is second bulge loop 23.Described first bulge loop 13 and all prefabricated the forming of described second bulge loop 23.And the button bit 41 of anchor ear rides on described first bulge loop 13 and second bulge loop 23, guarantees the not displacement in opposite directions in the axial direction of first pipe 1 and water inlet pipe 2.
Be to be that the example explanation is of the present invention with the metal pipe above, in fact, the present invention also is suitable for non-metallic pipe, and as using on the pipe of cement, concrete using method and said method are similar, here repeat no more.
