Detailed Description

As shown in the attached drawing, the invention comprises a valve body, a valve rod 2, a valve cover 3 and a wedge-shaped valve plate 4, wherein the valve rod 2 is movably arranged on the valve cover 3 through a packing sealing device and a feed screw nut, the top of the valve rod 2 is provided with a hand wheel 10, the valve cover 3 is connected with the valve body through a flange, the bottom of the valve rod 2 is movably connected with the wedge-shaped valve plate 4,

The valve body comprises a wedge-shaped valve plate accommodating shell 6, a liquid inlet pipeline 7 and a liquid discharge pipeline 8, wherein valve plate guide bulges are distributed on images in the wedge-shaped valve plate accommodating shell 6, a liquid discharge funnel 9 is arranged at the bottom of the wedge-shaped valve plate accommodating shell 6, the outlet end of the liquid discharge funnel 9 is communicated with the inlet end of the bottom sewage pipeline 5, the outlet end of the bottom sewage pipeline 5 is communicated with the inner cavity of the liquid discharge pipeline 8, flange plates are respectively arranged at the inlet end of the liquid inlet pipeline 7 and the outlet end of the liquid discharge pipeline 8, the outlet end of the liquid inlet pipeline 7 and the inlet end of the liquid discharge pipeline 8 are respectively communicated with the inner cavity of the wedge-shaped valve plate accommodating shell 6, the inlet of the liquid inlet pipeline 7 and the central line of the outlet of the liquid discharge pipeline 8 form an included angle alpha, the alpha is, the wedge valve plate 4 is slidably mounted in the wedge valve plate accommodating case 6.

The handwheel 10 may also be a valve electric actuator or a valve pneumatic actuator.

The cross-section of the sewage draining pipeline 5 is oval.

The inlet of the sewage pipe 5 is welded at the outlet end of the liquid discharge funnel 9, and the outlet end of the sewage pipe 5 is welded on the outer wall of the liquid discharge pipe 8.

The cross section of the inlet end of the drainage funnel 9 is oblong, and the cross section of the outlet end of the drainage funnel 9 is oval.

The working mode and principle are as follows: during the use, the staff installs the corner at sewage pipes with angular form blowdown gate valve, drive valve rod 2 through rotatory hand wheel 10 and make wedge valve plate 4 descend when not needing the blowdown, block up the valve body inner chamber, it passes through to block sewage, when needing the blowdown, rotatory hand wheel 10 drives valve rod 2 and makes wedge valve plate 4 rise, switch-on wedge valve plate holds casing 6, inlet fluid pipeline 7 and drain line 8, can the blowdown, it has the bottom that partial sewage deposit holds casing 6 at the wedge valve plate to return during the blowdown, discharge in the drain line 8 is sent into with sedimentary sewage through bottom drain line 5 at this moment. The cross section of the inlet end of the liquid discharge funnel 9 is oblong, so that the inlet end of the liquid discharge funnel 9 is more fit with the bottom of the accommodating shell 6 of the wedge-shaped valve plate, and the pollution discharge efficiency is improved.
