Abstract
The utility model relates to a device with connecting pipes and reducing joints. The device comprises the reducing joints (1), the connecting pipes (2) and a whistle-pipe (3), wherein the reducing joints (1) are in connected with the right ends of the connecting pipes (2) in an interference fit mode, the left ends of the connecting pipes (2) are connected with the whistle-pipe (3) in an interference fit mode, the sealing conical degree of the outer circle face of the right end of each connecting pipe (2) is 60 degrees, the sealing conical degree with a cone-shaped angle of 60 degrees is arranged in each reducing joint (1), each cone-shaped opening is a cone-shaped connector of 13-25mm, the sealing conical degree of the outer circle face of the right end of each connecting pipe (2) is 60 degrees and is in interference fit with the conical degree, being 60 degrees, of each reducing joint (1), and a groove with the width being 2mm and the depth being 0.5mm is formed at the position, 14mm far away from the end, of the left end of each connecting pipe (2). The device is applied to a spinning long frame and has good sealing performance due to improvement of the structures of the connecting pipes (2) and the reducing joints (1), and the size of a bore is changed, so that a negative pressure difference between a long frame head and a tailstock is reduced and consistency of quality of resultant yarns of an integral machine is ensured.
Description
Technical field
The utility model belongs to spinning frame long vehicle field, is specifically related to a kind of connecting tube and reducer union device.
Background technique
The spinning frame long vehicle is used flute pipe, reducing connecting tube and splice combinations form as shown in Figure 1 at present.Cooperating between flute pipe and the reducing connecting tube, reducing connecting tube and joint requires sealing, and reducing connecting tube taper mouth diameter is got different sizes, and the control suction air volume that evenly distributes according to certain rules guarantees that the negative pressure value of spinning frame headstock and the tailstock is reasonable.Yet in use sealing effect is also unreasonable, the subject matter that prior art exists is: the flute pipe inserts the degree of depth of reducing connecting tube and reducing connecting tube insertion joint and can't accurately control, cause the identical bad generation gas leakage of flute pipe and reducing connecting tube, the position of center line of reducing connecting tube can not meet the design attitude of spinning frame, insert the joint reduced diameter portion generation bending deflection of reducing connecting tube afterwards, filoplume in the suction connection can not smooth and easyly pass through, the final reducing connecting tube that stops up influences quality of yarn.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of connecting tube and reducer union device.
The technical solution of the utility model: a kind of connecting tube and reducer union device, it comprises reducer union 1, connecting tube 2 and flute pipe 3, reducer union 1 is connected with the right-hand member interference fit of connecting tube 2, the left end of connecting tube 2 is connected with flute pipe 3 interference fit, the right-hand member head periphery of connecting tube 2 is 60 ° sealing tapering, being provided with cone angle in the reducer union 1 is 60 ° of sealing taperings, taper mouth is 13～25 millimeters cone-shaped interface, and the right-hand member head periphery of connecting tube 2 is 60 ° sealing tapering and 60 ° of tapering interference fit of reducer union 1; 14 millimeters apart from termination places of the left end of connecting tube 2 are provided with the groove of 0.5 millimeter of wide 2 millimeters deep.
The utility model compared with prior art its beneficial effect is:
1. there is the wide groove of a 2mm elbow inside of connecting tube, the flanging at the flute mouth of pipe place close-fitting that matches with it, and gas leakage is avoided in fixing mounting point herein;
2. the 60o taper fit in the other end of connecting tube and the reducer union close-fitting, 60o tapering herein and reducer pipe guarantees sealing effect and mounting point;
3. the middle part of connecting tube has not had variable-diameter structure, and filoplume can smooth and easyly pass through, and improves quality of yarn;
4. the technology capability of connecting tube improves, and has improved manufacturing efficiency;
5. reducer union taper mouth diameter is got different sizes, the control suction air volume that evenly distributes according to certain rules, the negative pressure value of control spinning frame headstock and the tailstock.During final assembly, the control of mounting point has improved the installation quality.
