Model utility content
Technical problem to be solved in the utility model is to provide and a kind ofly can improves construction and installation efficiency, prevents that flange facing from producing the valve door flange damaging because of collision.
The valve door flange adopting for solving the problems of the technologies described above the utility model, comprise flange arrangement, left body, middle body, left body is arranged between flange arrangement and body and Zuo Tiyu body is fixedly connected with, flange arrangement and left body are Split type structure, pad in the middle of also comprising, in the middle of described, pad is between flange arrangement and left body, and flange arrangement, middle pad are fixedly connected with left body three.
Be further, flange arrangement also comprises slip joint, in the middle of described, pad is packing ring, also comprise bolt, on described slip joint, have bolt hole, on described left body, open the tapped hole matching with slip joint upper bolt hole, the bolt hole of described screw bolt passes slip joint, packing ring and left body are also threaded with the tapped hole of left body.
Further, the inner diameter of flange arrangement is identical with the inner diameter of left body.
Further, also comprise O type circle, described slip joint also comprises sealing surface, described left body also comprises seal boss, sealing surface coordinates with the outer surface of seal boss, and the outer surface of described seal boss also comprises seal groove, and described O type snare is located in seal groove.
Further, the inner diameter of flange arrangement is identical with the inner diameter of left body, also comprises truncated cone shape internal surface, and described truncated cone shape internal surface is between the inwall and sealing surface of flange arrangement.
Further, described left body also comprises guide ledges, and described slip joint also comprises interior guide surface, and described guide ledges also comprises outer guide surface, and outer guide surface is identical with the diameter of interior guide surface, and interior guide surface is set on outer guide surface.
The beneficial effects of the utility model are: because slip joint and left body are that Split type structure can allow pipeline reserve larger distance before installation, during installation, by the thickness of the distance between adjustment slip joint and left body and middle pad, adjust again the relative position of flange arrangement and companion flange, after flange arrangement is adjusted with the relative position of companion flange, just can carry out flange is connected, because pipeline before installing has been reserved larger distance, the operating space of therefore installing is large, easy for installation, improved the efficiency of construction and installation, and can prevent that in installation process, flange facing damages because collision produces.

Fig. 4 is the B partial view of Fig. 3;
Component, position and numbering in figure: companion flange 1, flange arrangement 2, left body 3, middle body 4, slip joint 6, bolt 7, packing ring 8, O type circle 9, sealing surface 11, seal boss 12, truncated cone shape internal surface 13, guide ledges 14, interior guide surface 15, outer guide surface 16.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, valve flanges of the present utility model, comprise flange arrangement 2, left body 3 and middle body 4, left body 3 between flange arrangement 2 and middle body 4 and left body 3 be fixedly connected with middle body 4, flange arrangement 2 is Split type structure with left body 3, pad in the middle of also comprising, described middle pad is between flange arrangement 2 and left body 3, and flange arrangement 2, middle pad are fixedly connected with left body 3 threes.Because flange arrangement 2 is Split type structure with left body 3, therefore, the distance between flange arrangement 2 and left body 3 can be adjusted.
Flange arrangement 2 also comprises slip joint 6.When concrete enforcement for easy for installation, before installation, can on pipeline, reserve segment distance L more, during installation, first left body 3 and middle body 4 are fixedly mounted, then flange arrangement 2 is lifted into the reserved location near left body, at this moment due to the segment distance L who reserves in advance of being separated by between flange arrangement 2 and companion flange 1, therefore there are enough spaces to carry out fitting operation and flange arrangement 2 and companion flange 1 and are not easy to bump.When overlapping, the center line of slip joint 6 and the center line of companion flange 1 again slip joint 6 is moved horizontally to L distance to companion flange direction, at this moment between slip joint and left body, by producing distance, be the gap of L, this gap available thickness is that the middle pad of L is filled up, and finally respectively flange arrangement 2 is fixedly mounted with companion flange 1 and left body.
Method that can be preferably following is fixed connection to slip joint 6 and left body 3, middle pad adopts packing ring 8, also comprise bolt 7, on slip joint 6, have bolt hole, on left body 3, open the tapped hole matching with slip joint 6 upper bolt holes, bolt 7 passes successively bolt hole, packing ring 8 and the left body 3 of slip joint 6 and is threaded with the tapped hole of left body 3.Can first packing ring 8 during concrete enforcement put into the space between slip joint 6 and left body 3 and then with bolt 7, three is fixedly connected with.
During design, can make the inner diameter of flange arrangement 2 identical with the inner diameter of left body 3, can make like this caliber of pipeline be consistent to greatest extent, so that fluid flowing in pipeline is more stable.
Because flange arrangement 2 and left body 3 have been made Split type structure, in order to guarantee that the sealability of pipe-line system needs sealing when both are fixed to connection, specifically can adopt following sealing configuration, as shown in Figure 3, sealing configuration also comprises O type circle 9, and sealing surface 11 is set on slip joint 6, on left body 3, seal boss 12 is set, sealing surface 11 coordinates with the outer surface of seal boss 12, and the outer surface of seal boss 12 is also provided with seal groove, and O type circle 9 is set in seal groove.
Identical with the inner diameter of flange arrangement 2 in order to guarantee left body 3 when adopting above-mentioned sealing configuration, the diameter of the sealing surface 11 on slip joint 6 is greater than flange arrangement 2 inner diameters, between different diameters, need transition structure, for head it off is provided with truncated cone shape internal surface 13, truncated cone shape internal surface 13 is between the inwall and sealing surface 11 of flange arrangement 2.Truncated cone shape internal surface 13 has been realized flange arrangement 2 inner diameters seamlessly transitting to the diameter of sealing surface 11, can reduce the active force of fluid to inwall, effectively prevent the generation of stress concentration phenomenon, when fluid is flowed through herein in addition, can not produce vortex phenomenon because flow velocity and direction sharply change.
The left body 3 of the utility model valve flanges also comprises guide ledges 14, and slip joint 6 also comprises interior guide surface 15, and guide ledges 14 also comprises outer guide surface 16, and outer guide surface 16 is identical with the diameter of interior guide surface 15, and interior guide surface 15 is set on outer guide surface 16.Because interior guide surface 15 is set on outer guide surface 16, so the center line of slip joint 6 overlaps with the center line of left body 3, in in apart from adjustment process, guide surface 15 can move axially along outer guide surface 16, the center line of slip joint 6 and the center line of left body is in course of adjustment and overlaps all the time.
