The utility model is set to further: the first described groove and the second groove are respectively circular groove, and seal ring is O type circle, and the ratio of described first groove or the degree of depth of the second groove and the diameter of seal ring is 0.85-0.95.
The utility model is set to further: described connecting tube comprises connection mouth, and the perpendicular distance between the first groove and connection mouth and the lenth ratio of connecting tube are 0.2-0.3.
The utility model is set to further: the perpendicular distance between described second groove and connection mouth and the lenth ratio of connecting tube are 0.75-0.85.
The utility model is set to further: the pipe thickness of described linkage section is 3-5mm.
The beneficial effects of the utility model are: 1, the utility model is by arranging the first groove and the second groove in connecting tube, and be respectively equipped with seal ring in the first groove and the second groove, pipeline can be made to be pressed in connecting tube, seal ring carries out seal action to it, thus makes the installation or removal of pipeline more convenient.2, the utility model comprises strengthening segment and linkage section by arranging connecting tube, the thickness of strengthening segment is greater than linkage section, because the length of connecting tube is long, the intensity of connecting tube is reduced, if increase the intensity of connecting tube, and the intensity of whole piece connecting tube is all increased, the weight of ball valve is then not only made greatly to strengthen, be unfavorable for the use of ball valve, and improve cost of production, so only need the intensity of connecting tube near one end of valve body to increase, considerably increase the intensity of connecting tube, thus improve the working life of ball valve.4, the utility model is 3-4 by arranging the thickness ratio of strengthening segment and linkage section, fix at the thickness one of linkage section, if this ratio is too little, then the thickness of strengthening segment is less, cause the insufficient strength of connecting tube, if this ratio is too large, then the thickness of strengthening segment is just too large, although the intensity of connecting tube is very large, but considerably increase the cost of production of ball valve, so the thickness ratio limiting strengthening segment and linkage section is 3-4, can ensures in this ratio range that the intensity of connecting tube is best, thus improve the working life of ball valve.5, the utility model is 0.25-0.35 by arranging the lenth ratio of strengthening segment and connecting tube, equally, fix in connecting tube length one, if this ratio is too large, then the length of strengthening segment is just too large, considerably increase the cost of production of ball valve, if this ratio is too little, then the length of strengthening segment is just too little, makes the length of connecting tube inadequate, so the lenth ratio limiting strengthening segment and connecting tube is 0.25-0.35, can ensure that in this ratio range the intensity of connecting tube is best.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of clamping type ball valve of the utility model.
Reference character in figure: valve body 1, connecting tube 2, strengthening segment 3, linkage section 4, the first groove 5, second groove 6, annular protrusion 7, seal ring 8.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
With reference to figure 1, a kind of clamping type ball valve, comprise valve body 1 and be placed in the connecting tube 2 of valve body 1 both sides respectively, described connecting tube 2 comprises strengthening segment 3 and linkage section 4, the center line of strengthening segment 3 and linkage section 4 is on same straight line, the thickness of strengthening segment 3 is greater than linkage section 4, strengthening segment 3 one end and valve body 1 are by being fixedly connected with, the other end is connected with linkage section 4, the first groove 5 is provided with in described strengthening segment 3, the second groove 6 is provided with in linkage section 4, the outer wall of corresponding linkage section 4 there is annular protrusion 7, the deep equality of described first groove 5 and the second groove 6, seal ring 8 is respectively equipped with in first groove 5 and the second groove 6, described strengthening segment 3 is 3-4 with the thickness ratio of linkage section 4, described strengthening segment 3 is 0.25-0.35 with the lenth ratio of connecting tube 2.Wherein, by arranging the first groove 5 and the second groove 6 in connecting tube 2, and being respectively equipped with seal ring 8 in the first groove 5 and the second groove 6, pipeline can be made to be pressed in connecting tube 2, seal ring 8 carries out seal action to it, thus makes the installation or removal of pipeline more convenient.Strengthening segment 3 and linkage section 4 is comprised by arranging connecting tube 2, the thickness of strengthening segment 3 is greater than linkage section 4, because the length of connecting tube 2 is long, the intensity of connecting tube 2 is reduced, if increase the intensity of connecting tube 2, and the intensity of whole piece connecting tube 2 is all increased, the weight of ball valve is then not only made greatly to strengthen, be unfavorable for the use of ball valve, and improve cost of production, so only need the intensity of connecting tube 2 near one end of valve body 1 to increase, considerably increase the intensity of connecting tube 2, thus improve the working life of ball valve.Be 3-4 by arranging strengthening segment 3 with the thickness ratio of linkage section 4, fix at the thickness one of linkage section 4, if this ratio is too little, then the thickness of strengthening segment 3 is less, cause the insufficient strength of connecting tube 2, if this ratio is too large, then the thickness of strengthening segment 3 is just too large, although the intensity of connecting tube 2 is very large, but considerably increase the cost of production of ball valve, so limiting strengthening segment 3 with the thickness ratio of linkage section 4 is 3-4, can ensures in this ratio range that the intensity of connecting tube 2 is best, thus improve the working life of ball valve.Be 0.25-0.35 by arranging strengthening segment 3 with the lenth ratio of connecting tube 2, equally, fix in connecting tube 2 length one, if this ratio is too large, then the length of strengthening segment 3 is just too large, considerably increase the cost of production of ball valve, if this ratio is too little, then the length of strengthening segment 3 is just too little, makes the length of connecting tube 2 inadequate, so limiting strengthening segment 3 with the lenth ratio of connecting tube 2 is 0.25-0.35, can ensure that in this ratio range the intensity of connecting tube 2 is best.
In order to increase the sealing effect of clamping type ball valve, the first described groove 5 and the second groove 6 are respectively circular groove, and seal ring 8 is O type circle, and the ratio of described first groove 5 or the degree of depth of the second groove 6 and the diameter of seal ring 8 is 0.85-0.95.Described connecting tube 2 comprises connection mouth, perpendicular distance between first groove 5 and connection mouth and the lenth ratio of connecting tube 2 are 0.2-0.3, perpendicular distance between described second groove 6 and connection mouth and the lenth ratio of connecting tube 2 are 0.75-0.85, and the first groove 5 and the second groove 6 can be made like this to seal to pipeline respectively.
In order to increase the intensity of connecting tube 2 further, the pipe thickness of described linkage section 4 is 3-5mm.
The foregoing is only preferred embodiment of the present utility model, is not restriction with the present embodiment, all make within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
