For solving the problems of the technologies described above, the mediation valve of the magnesium oxide conveyance conduit that the anti-bend of the utility model stops up comprises valve body, valve gap, spool, double-screw bolt push rod; rocking handle; first seal ring and second seal ring; described valve body is a cylindrical body; described valve body top is provided with valve gap; bottom end opening; described valve body middle part has circular hole and mounting flange; described spool comprises first cylindrical body; second cylindrical body and connecting rod; described first cylindrical body is connected by described connecting rod with second cylindrical body; described spool is positioned at described valve body; described first seal ring and second seal ring are located at respectively on first cylindrical body of described spool and second cylindrical body and are used to seal described spool and valve body; the valve gap center of described valve body is provided with screw; described screw rod push rod is twisted in the screw of described valve gap the first cylindrical body end face that an end also is movably connected on described spool, and described rocking handle is fixed at the other end of described screw rod push rod.
Smooth and easy for making the screw rod push rod promote spool, this mediation valve also comprises leading truck, described leading truck comprises two straight-bars and a cross bar, described two straight-bar one ends are vertical on the valve gap of described valve body respectively at interval, described cross bar two ends connect the other end of described two straight-bars respectively, described cross bar center has through hole, and described screw rod push rod is positioned at the through hole of described cross bar.
When conveyance conduit magnesium oxide is normally carried, avoid unexpected the moving of screw rod push rod to cause the misoperation of this mediation valve, this mediation valve also comprises nut, described nut is twisted on described screw rod push rod and is positioned at the valve gap outside of described valve body.
Because the mediation valve of the magnesium oxide conveyance conduit that the anti-bend of the utility model stops up has adopted technique scheme, promptly be provided with valve gap on the top, bottom end opening, the cylindrical body that the middle part has circular hole and mounting flange constitutes valve body, two sections cylindrical bodys that connected by connecting rod constitute spool, spool is positioned at valve body, two seal rings are located at respectively on two sections cylindrical bodys of spool and are used for sealed valve core and valve body, the valve gap center is provided with screw, the screw rod push rod is twisted in the screw of valve gap and a cylindrical body end face of an end and spool flexibly connects, and rocking handle is fixed at the other end of screw rod push rod; Utilize this mediation valve can conveniently carry out the mediation operation of conveyance conduit, improved mediation efficient, and need not cut off conveyance conduit, guaranteed the normal conveying of raw materials of magnesium oxide.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the mediation valve of the magnesium oxide conveyance conduit of the anti-bend obstruction of the utility model,
The schematic representation that Fig. 2 is connected with the magnesium oxide conveyance conduit for this mediation valve.
Embodiment
As shown in Figure 1; The dredge valve of the magnesium oxide delivery pipeline that the anti-bend of the utility model stops up comprises valve body 1; Spool; Valve gap 8; Double-screw bolt push rod 5; Rocking handle 6; First sealing ring 9 and second sealing ring 10; Described valve body 1 is a cylinder; Described valve body 1 top is provided with valve gap 8; Bottom end opening; Described valve body 1 middle part has circular hole and mounting flange 7; Described spool comprises first cylinder 2; Second cylinder 3 and connecting rod 4; Described first cylinder 2 be connected cylinder 3 and connect by described connecting rod 4; Described spool is positioned at described valve body 1; Described first sealing ring 9 and second sealing ring 10 are located at respectively and are used for sealing described spool and valve body 1 on first cylinder 2 of described spool and second cylinder 3; Valve gap 8 centers of described valve body 1 are provided with screw; Described screw rod push rod 5 is twisted in the screw of described valve gap 8 and an end is movably connected on first cylinder, 2 end faces of described spool, and described rocking handle 6 is fixed at the other end of described screw rod push rod 5.
Smooth and easy for making screw rod push rod 5 promote spool, this mediation valve also comprises leading truck, described leading truck comprises two straight-bars 11 and a cross bar 12, described two straight-bar 11 1 ends are vertical on the valve gap 8 of described valve body 1 respectively at interval, described cross bar 12 two ends connect the other end of described two straight-bars 11 respectively, described cross bar 12 centers have through hole, and described screw rod push rod 5 is positioned at the through hole of described cross bar 12.Screw rod push rod 5 is subjected to leading truck cross bar 12 through holes when moving spacing make move more reliable, smooth and easy.
