Pipe tee design drawings
DataTime:[2016-7-25]
Pipe tee is a duct system bifurcate or collection role of pipe fittings. Three links, sort is more, in the form of a diagonal tee, straight tee, pants fork tee, elbow combined tee, etc. Now only introduce commonly used circular tee and rectangular tee.
(1) the circular tee
As shown in figure 5 to 17 circular tee, the continuation of duct part 1 is called tee "director", branch part 2 referred to as the "branch" tee. D: said big diameter, D: small hole diameter, D3 said branch pipe diameter, the height of the H t, mouth said executives and branch pipe axis Angle.
Executives and branch pipe axis Angle a, should according to the tee to determine the diameter size, generally is 15 ° ~ 60 °, a Angle is small, the height of the tee is bigger, a larger Angle, the height of the tee is smaller. When machining large diameter tee, in order to avoid the 3-way height is too large, large Angle should be adopted. General ventilation system of tee Angle is 15 ° ~ 60 ° 15 ° to 30 ° dust removal system can be used.
Executives and branch pipe edge deflection distance between S and should be able to ensure easy mounting flange, and flange bolt fastening.
To tee off, should be according to the size of three links of the known underline main view, as shown in figure.
Begins to draw A straight line on the plank to intercept A - B is equal to big diameter, the midpoint 0 draw vertical lines from A - B 0-0 ', 0-0 at A height of three links' online interception of O - P, the P point lead AB parallel lines, and section c-d is equal to the small hole diameter, with fixed-point C and D. Use connect AC and BD for a quick, head of the main view. Again from zero point to determine a Angle, lead 0-0 line, from the points of D 0-0 "of the vertical line intersect at point M, with a midpoint of M,
In this online interception of EF is equal to the branch pipe diameter, with straight line connection EA and FB, namely get three main view. In the main view of tee K line 0, 0 K line is the tee joint line supervisor and branch pipe.
The 3-way head start as shown in figure 5-19. According to the shape of the head on the main view to the big and small hole according to the diameter of auxiliary semicircle, six equal to circle, and number in order to make the corresponding contour line, as shown in figure (a). Methods according to the size of the head, will then head into a fan, as shown in figure 5-19 (b). Interception in sector 7 K, equal to the DK on the main view, interception of 6 m, equal to (a) on the graph real 7 m long, 6 m, intercept 5 N1 equals 5 n (a) on the drawing, real 7 n, long, finally will be K, M1, N1, 4 together as smooth curve, the 3-way head part of the expansion plan.
As shown in figure of tee branch pipe. Branch expansion, also make the auxiliary semicircle, and divided into six parts, and according to the order number, draw the corresponding contour line. Expansion method, and then press circle size head will branch expansion into the sector. Again separately interception in the sector 1 k_ is equal to the UK on the main view, 2 m, equal to 2 m real long 7 M1, 3 n equals 3 n real long 7 n, and this can determine K, M1, N1 three points. Then intercept 5 C2 is equal to 5 c real long 7 c1, 6 d: equal to 6 d real long 7 d1, 7 B is equal to 7 B, fixed-point C2 and D2, B, final connection points each, for a quick (half) of tee branch pipe.
This method is simple, widely used on the site, but has the certain error. If the duct diameter is larger, can be appropriately increase the auxiliary of semicircle of scores, the error will be smaller. Tee, draw after good expansion plan, according to the connection method to set aside bite allowance and allowance of the flange, with mechanical or manual cutting. The connection of the joint of three forms, should be based on the material, thickness of the plank. Thickness is less than 1.2 mm galvanized steel and ordinary steel sheet, can be used to bite. Thickness is greater than 1.2 mm galvanized steel plate can be used riveting. Ordinary steel sheet thickness is greater than 1.2 mm can use welding. Bite connection includes cutting the connection.
When using cuttings, executives and branch pipe can be bite, roll round, respectively the bite compaction, processed into independent parts and mating part on the flat plate check whether match, then pick up joint work ruffled, fold branch and head into a single ruffled, as shown in figure.
Will be processed cutting, gently with wooden hammer into tee joint inside, make the head and branch closely joint, with a small hammer and lining iron, will be cutting matter
Ping.
When connected by welding, available to the joint form. If the plate is thinner, can meet commissural plate on 5 mm vertical edge, reoccupy welding welding.
When using bite connection available coverage method (commonly known as the big bite). The commencement, the longitudinal closed bite at side. Operation, the cutting board, first making good longitudinal closed bite, the deployment manager on branch, with a figure of step processing by joint bite, then by hand by executives and branch pipe, the joint matter, draw, as shown in figure 3 and 4. Finally rolled the executives and branch circle, and matter draw with longitudinal closed bite, then t find round and finishing work.
Circular duct tee connected by bite, also can make answer the commissure a single bite of form, and then put the bite humans, and finishing.
