Description

Irrigate thin-walled Zhi Guanyong socket joint bypass
Technical field
The present invention relates to the connecting branch of field of farm irrigation use and a kind of socket pipe member of drip irrigation zone, particularly irrigate thin-walled Zhi Guanyong socket joint bypass.
Background technique
In irrigation system, the link of arm and hollow billet or drip irrigation zone is called bypass.
Fig. 1 and Fig. 2 is the by-pass structure schematic diagram for heavy wall arm.Wherein, Fig. 1 is the most frequently used without screw socket socket joint bypass, and left side is bypass inlet, is connected with arm; Right side is Bypass outlet and hollow billet locking nut, is connected with hollow billet.
Bypass and arm adopt plug-in type to be connected, namely bypass taper inserting paragraph 11 is inserted in the branch pipe wall had openning hole in advance, utilize the elasticity of heavy wall PE arm and toughness to be stuck in bypass inserting paragraph reducing bottom surface 12 place, finally utilize hollow billet locking nut 13 to connect hollow billet and bypass.
Fig. 2 is screw socket socket joint bypass, and it adds turnbuckle 23 on the basis of Fig. 1, and bypass can be made to be fixed on more firmly on heavy wall PE arm.First turnbuckle 23 is inserted in bypass inserting paragraph 21 (internal thread diameter of turnbuckle 23 is more bigger than the diameter of inserting paragraph reducing bottom surface 22) during use to the right, and screws on the outside thread 24 on the right side of inserting paragraph 21; Then bypass inserting paragraph 21 is inserted in the heavy wall PE arm had openning hole; By the turnbuckle 23 that circles round, heavy wall PE arm is clipped between turnbuckle 23 and bypass inserting paragraph 21 left; Hollow billet locking nut 25 is finally utilized to connect hollow billet and bypass.
When arm is thin-walled PE pipe, the thickness of arm, elasticity and toughness all reduce, and the inserting paragraph 11 without screw socket socket joint bypass in Fig. 1 easily comes off from arm; And for the screw socket socket joint bypass in Fig. 2, when the turnbuckle 23 being inserted in screw thread 24 circles round to left movement, because its internal thread diameter is greater than the diameter of inserting paragraph reducing bottom surface 22; thin-walled PE tube wall can be absorbed in the gap between turnbuckle and bypass inserting paragraph; form the card trace of a ring-type; and outwards turn down; and constantly thinning under the spin friction, squeezing action of turnbuckle; be finally separated with bypass inserting paragraph, namely bypass inserting paragraph 21 is easy to spin off from arm under the reaction force of turnbuckle.
Therefore, for thin-walled arm, adopt by-pass structure form as shown in Figure 3 and Figure 4 at present.Two kinds of bypass of Fig. 3 and Fig. 4, by inserting paragraph, turnbuckle, hollow billet linkage section three part composition.Fig. 3 and Fig. 4 is respectively the formula of being threaded into and hooks formula.The turnbuckle internal thread diameter of two kinds of bypass is all less than bypass inserting paragraph reducing basal diameter, and turnbuckle external diameter equals bypass inserting paragraph reducing basal diameter.Bypass inserting paragraph (31 and 41) is all first inserted in the thin-walled PE arm had openning hole by their installation method, then the outside thread (34 and 44) of turnbuckle (33 and 43) from bypass inserting paragraph (31 and 41) right side is screwed in left, and tighten, due to turnbuckle (33 and 43) external diameter and inserting paragraph reducing bottom surface (32 and 42) equal diameters, therefore thin-walled arm can be firmly sandwiched between inserting paragraph reducing bottom surface (32 and 42) and turnbuckle (33 and 43) front-end face; Finally bypass afterbody 35 is screwed in the internal thread 36 on the right side of bypass inserting paragraph 31 or by bypass afterbody 45 and is screwed in the internal thread 46 of turnbuckle 43.
But the parts of kind of the bypass of two shown in Fig. 3 and Fig. 4 are four part compositions, and complex structure, cost of production is higher, and installation process is comparatively complicated, the engineering time is longer.
Therefore, the irrigation thin-walled Zhi Guanyong socket joint bypass that a kind of cost of production is low, easy for installation, be connected firmly is badly in need of in prior art.
Summary of the invention
For the problems referred to above, the present invention aims to provide and a kind of irrigates thin-walled Zhi Guanyong socket joint bypass, and its cost of production is low, easy for installation, be connected firmly, and then solves the above-mentioned problems in the prior art.
For achieving the above object, technological scheme provided by the invention is, a kind of irrigation thin-walled Zhi Guanyong socket joint bypass, comprises pipe fitting, turnbuckle and hollow billet locking nut.
The compound shape pipe that described pipe fitting is one of the forming, comprises inserting paragraph, arm locking section, main body screw section, thread groove section, hollow billet locking section and bypass afterbody; Described inserting paragraph is circular cone structure, and the basal diameter of described circular cone is Φ 1mm, described inserting paragraph is close to one end of described arm locking section by reducing bottom surface, and described arm locking section diameter is Φ 2mm, and Φ 2diameter be less than Φ 1diameter; The other end of described arm locking section is close to one end of described main body screw section, and the diameter of described main body screw section is more bigger than described inserting paragraph basal diameter; The other end of described main body screw section is close to one end of described thread groove section; The other end of described thread groove section connects one end of described hollow billet locking section; The other end of described hollow billet locking section is close to one end of described bypass afterbody, and described bypass afterbody is circular cone structure, and its other end is connected with hollow billet, and fixes with hollow billet locking nut.
Adjacent described of turnbuckle front end edge circumference is provided with some trapezoidal latches extended along direction, the center of circle, and form a ring structure, the thickness of described trapezoidal latch is about 1mm, employing elastic material is made, stressed energy distortion, and restorability is good, is one of the forming with turnbuckle; The outer diameter of described trapezoidal latch is Φ 4mm, with the basal diameter Φ of the circular cone of the described inserting paragraph of pipe fitting 1identical or bigger, the inner diameter Φ of the trapezoidal latch of described ring-type 5mm and described arm lock the diameter of phi of section 2mm is identical.
Further, the described main body screw on the internal thread of described turnbuckle and described pipe fitting is suitable, its internal thread diameter Φ 3mm is than the basal diameter Φ of the inserting paragraph reducing of described pipe fitting 1mm is bigger, the thread section length L of the internal thread of described turnbuckle 2than the length L of described arm locking section 1long.
Further, the outer surface of described turnbuckle is provided with multiple boss, and described boss is arranged at equal intervals along the circumference of described outer surface, and described boss extends along the axial direction of described turnbuckle.
Further, the basal diameter Φ of described inserting paragraph 1for 16.5mm, the diameter of phi of described arm locking section 2for 12mm, the internal thread diameter Φ of described locking nut 3for 16.7mm, the outer diameter of described trapezoidal latch is Φ 4for 16.5mm, the inner diameter of described trapezoidal latch is Φ 5for 12mm, the length L of described arm locking section 1for 8mm, the thread section length L of the internal thread of described turnbuckle 2for 15mm.
The present invention is owing to adopting such scheme, there is following beneficial effect: 1, because the trapezoidal latch on turnbuckle is flexible, therefore turnbuckle can directly penetrate from pipe fitting inserting paragraph and not need pipe fitting to be divided into two sections so that turnbuckle screws in (as shown in Figure 3 and Figure 4) from thinner stage casing, this can not only reduce cost of production, can also save the installation time; 2, the main body screw entered on pipe fitting when turnbuckle starts convolution when moving to inserting paragraph direction, and thin-walled arm can be sandwiched securely between the trapezoidal latch of restorable ring-type and pipe fitting inserting paragraph reducing bottom surface.
