Above-mentioned valve connection interface; The said cross section that compresses seal ring is a right-angled triangle; Its two right angle sides are respectively inner side surface and the bottom surface that compresses seal ring, and inner side surface contacts with the outer wall of connecting tube, and the bottom surface contacts with the protruding last Transverse plane of compression plate; Hypotenuse is the outer side surface that compresses seal ring, and the angle of inclination of outer side surface and valve adpting flange inwall groove are complementary.
Adopt the valve connection interface of this structure; The compression plate convexity is up along the groove of valve adpting flange; The protruding upper end of compression plate will compress the seal ring pushing tow that makes progress; Compress the outer wall that seal ring clamps connecting tube, compression plate closely is connected by connecting bolt with the valve adpting flange, thereby through compressing seal ring connecting tube closely is connected with valve.The utility model is simple in structure, easy to use, it is closely reliable to connect, it is easy, with low cost to make, and can in being connected of valves such as various gate valves, stop valve, ball valve, butterfly valve, safety check, filter, irrigation control valve and pipeline, use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode figure of the utility model.
Mark is following among the figure: valve body 1, valve adpting flange 2, groove 3, compression plate 4, protruding 5, screw 6, connecting bolt 7, compress seal ring 8, connecting tube 9, spacing preiection 10, angle.
Embodiment
Show among the figure that the utility model comprises valve adpting flange 2, compression plate 4, compresses seal ring 8.Valve adpting flange 2 is the part of the valve body 1 of original valve; Compression plate 4 is the ring square position, and connecting tube 9 directly inserts in the valve adpting flanges 2 and connects, this structure need be on pipeline welded flange or use the joint socket flange; Simplify the structure, reduced cost.
Show among the figure, in the utility model, need the valve adpting flange 2 on original valve be improved that this improvement should be accomplished in the lump when making valve, and after the valve manufacturing is accomplished, do not reprocess, with time saving and energy saving.
The improvements of valve adpting flange 2 are the grooves that the inwall circumference of the opening of valve adpting flange 2 changed into inclination, and the angle of groove inclined-plane and flange inner wall is the 5-85 degree.This improvement is easy to accomplish when making valve.
Show among the figure; What be used with valve adpting flange 2 is compression plate 4; Compression plate 4 is an annular disc; Its external diameter, internal diameter are complementary with external diameter, the internal diameter of valve adpting flange 2 respectively, are evenly equipped with screw 6 on the compression plate 4 and are complementary with the screw that is connected of valve adpting flange 2, by connecting bolt 7 compression plate 4 and valve adpting flange 2 are fastenedly connected.
Show among the figure, compress seal ring 8 and be flexible rubber ring, compress the internal diameter of seal ring 8 and the external diameter of connecting tube 9 to be complementary, compress the external diameter of seal ring 8 and the outer opening diameter of valve adpting flange 2 inwall grooves 3 and be complementary.
Compress the seal ring that seal ring 8 can adopt common circular section, compress the back by compression plate 4 and produce deformation, realize being connected with the tight of connecting tube 9.But be to use the better effects if of the seal ring of special cross-section shape; The utility model adopt the cross section be right-angled triangle compress seal ring 8, its two right angle sides are respectively inner side surface and the bottom surface that compresses seal ring 8, inner side surface contacts with the outer wall of connecting tube 9; The bottom surface contacts with the last Transverse plane of compression plate protruding 5; Hypotenuse is the outer side surface that compresses seal ring 8, and the angle of inclination of outer side surface and valve adpting flange 2 inwall grooves 3 are complementary, and is tight more and firm when compressing like this.
Show among the figure that the spacing preiection 10 that on the inwall of valve adpting flange 2, has connecting tube 9 to insert, connecting tube 9 can not insert dark or shallow excessively by spacing preiection 10 location after inserting valve adpting flange 2.Spacing preiection 10 can have a plurality of along the inwall circumference of valve adpting flange 2, or is ring-type, when making valve, accomplishes simultaneously.
Show among the figure; The internal diameter of valve adpting flange 2 and compression plate 4 is greater than the external diameter of connecting tube 9; Be convenient to the insertion of connecting tube 9 like this; Gap between them should make inserts smoothly, after compression plate 4 is fastening, reaches simultaneously not to be connected firmly, closely, do not reveal, therefore should be according to the outer bore valve design door adpting flange 2 of standard pipe and the internal diameter of compression plate 4.
The utility model in use; At first the end at connecting tube 9 puts compression plate 4 and compresses seal ring 8, and the last Transverse plane of compression plate protruding 5 contacts with the bottom surface that compresses seal ring 8, then connecting tube 9 is inserted valve adpting flange 2; Be inserted into spacing preiection 10; With pushing away on the compression plate 4, penetrate connecting bolt 7 again, compression plate 4 is connected with valve adpting flange 2.At this moment compression plate protruding 5 is up along the groove 3 of valve adpting flange 2; The upper end of compression plate protruding 5 will compress upwards pushing tow of seal ring 8; Compress the outer wall that seal ring 8 clamps connecting tube 9, tighten connecting bolt 7, connecting tube 9 closely is connected with valve through compressing seal ring 8.
