The utility model discloses on the basis of T shape tee bend pipe fitting commonly used, make the tee bend pipe fitting the symmetrical convex shunt tubes of the similar butterfly wing of shape and advance water piping connection, and through the excessively water sectional area of increase inlet tube with left convex shunt tubes and right convex shunt tubes link, runner with inlet tube and left convex shunt tubes and right convex shunt tubes changes the arcuation into by right angle shape simultaneously, thereby make it reach the reduction water flow velocity, reduce water swirl formation volume, and then reduce local head loss coefficient, reach the mesh that reduces the head loss volume.
Description
Technical field
This utility model is related to a kind of butterfly tee pipe fitting structure, belongs to tee pipe fitting technical field.
Background technology
Conventional T tube part, is square in diffluence pass infall, i.e. right-angle tee, due to its local head loss
1.5 about, therefore, the loss of its working head is relatively large for coefficient.Wang Jinghua in 2006 et al. is in field drip irrigation under mulch in Xinjiang
Engineering measurement T-shaped isometrical shunting Three-way pipe with snap fastener local (water resistance) loss reduction also in 0.5m (land for growing field crops under-film drip irrigation systems technology
Some problems in design, author:Wang Jinghua, Rong Hangyi, Wang Deci, Gao Wenshan《Water-saving irrigation》4th phase P46 in 2006).Root
According to《Slight irrigation engineering technology》Specify in SL103-95 specification, for when using non-compensating drop irrigation head, calculating arm and being connected with hollow billet
It is assigned to hollow billet or arm working head tolerance typically in 1.5m, if threeway local head loss (water resistance) exists
0.5m, will account for 33% about, therefore directly affect hollow billet or arm laying length.Therefore, existing T tube part work
The loss of flood peak is serious, and it is not ideal enough that the application in engineering irrigation shows.
Utility model content
The purpose of this utility model there are provided that a kind of structure is simple, low manufacture cost, butterfly threeway easy to use
Fitting structure, to increase discharge section area, reduces water flow velocity, and the design of circular arc water flow passage can reduce water scroll
Cheng Liang, thus reducing the requirement of local loosening, local head loss's amount when reducing pipe fitting work.
The technical solution of the utility model：A kind of butterfly tee pipe fitting structure, it is by water inlet pipe and to be symmetrically connected to
The tee pipe fitting that the left circular arc isocon of water inlet pipe one end and right circular arc isocon are constituted, described left circular arc isocon
Be curve bend with right circular arc isocon, the cross sectional shape of its internal diameter from the oval water inlet with water inlet pipe connection end to
The gradually transition of the circular outlets of the other end.
The sectional area of described ellipse water inlet is more than the sectional area of circular outlets.
The radian of described left circular arc isocon and right circular arc isocon is 60～70 degree.
Roof junction between described left circular arc isocon and right circular arc isocon is provided with arc convex and is connected,
And the inwall of arc convex is arc-shaped recess structure the interior walls be smooth mistake of circular arc isocon and right circular arc isocon to the left
Cross.
Due to adopting technique scheme, the utility model has the advantage of：This utility model is in conventional T tube part
On the basis of, the symmetric, arc isocon that tee pipe fitting making is shaped like butterfly's wing shape is connected with water inlet pipe, and leads to
Cross the discharge section area increasing water inlet pipe and left circular arc isocon and right circular arc isocon connection end, simultaneously by water inlet pipe
With the runner of left circular arc isocon and right circular arc isocon, Curved is changed to by square, so that it reduces current
Speed, reduces water whirlpool forming amount, and then reduces local loosening, reduces the purpose of loss of flood peak amount.Therefore, will
This utility model is used in existing engineering irrigation and can improve uniformity of irrigation water appilcation it is ensured that irrigation quality, and new construction can increase hollow billet
Or arm laying length, reduce main laying length, reduce construction fund.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, right with reference to the accompanying drawings and examples
This utility model is described in further detail.
Embodiment of the present utility model：As shown in Figures 1 to 3, it is by entering to the structural representation of butterfly tee pipe fitting structure
Water pipe 1 and be symmetrically connected to the tee T that the left circular arc isocon 2 of water inlet pipe 1 one end and right circular arc isocon 3 are constituted
Part, described left circular arc isocon 2 and right circular arc isocon 3 are curve bend, the cross sectional shape of its internal diameter by with enter
The gradually transition of the circular outlets 5 to the other end for the oval water inlet 6 of water pipe 1 connection end, and the cutting of oval water inlet 6
Area is more than the sectional area of circular outlets 5；The radian of described left circular arc isocon 2 and right circular arc isocon 3 is 65
Degree.Referring to Fig. 4, the roof junction between described left circular arc isocon 2 and right circular arc isocon 3 is provided with arc convex
4 connections, and the inwall of arc convex 4 is the interior of arc-shaped recess structure circular arc isocon 2 and right circular arc isocon 3 to the left
Wall seamlessly transits.Therefore, to not only increase left circular arc isocon 2 strong with the connection of right circular arc isocon 3 for arc convex 4
Degree, and increase the discharge section area of water inlet pipe 1 and left circular arc isocon 2 and right circular arc isocon 3 junction, from
And reach reduction water flow velocity, reduce water whirlpool forming amount, reduce the purpose of loss of flood peak amount.
This utility model, on the basis of conventional T tube part, tee pipe fitting is made and is shaped like butterfly's wing shape
Symmetric, arc isocon be connected with water inlet pipe, and by increase water inlet pipe 1 divide with left circular arc isocon 2 and right circular arc
The discharge section area of flow tube 3 connection end, simultaneously by the stream of water inlet pipe 1 and left circular arc isocon 2 and right circular arc isocon 3
Road is changed to Curved by square, so that it reduces water flow velocity, reduces water whirlpool forming amount, and then reduces local head
Loss coefficient, reduces the purpose of loss of flood peak amount.Therefore, this utility model is used in existing engineering irrigation and can improve filling
It is ensured that irrigation quality, new construction can increase hollow billet or arm laying length to the water uniformity, reduce main laying length, reduce
Construction fund.
