The flange type right-angle shut-off valve is compact in structure, good in sealing effect, long in service life and convenient to operate.
Description
Technical field
The utility model relates to valve, and especially a kind of good seal is convenient for changing the flange-type angle shut-off valve of easily damaged parts.
Background technique
At present, existing stop valve generally is common cock-type or flat stifled formula structure, and material mainly is cast iron, and existing stop valve exists valve mechanism complicated usually, and intensity is not high, and is not wear-resistant, easy to leak, the shortcoming such as working life is short.Existing cast steel stop valve is affected so that seal because working ability is limit, and its structure is comparatively simple, and the replacing of the easily damaged parts of stop valve is convenient not.
The model utility content
The purpose of this utility model provides a kind of good seal, is convenient to change easily damaged parts, and the flange-type angle shut-off valve of growing working life.
The purpose of this utility model is achieved by the following technical solution:
The flange-type angle shut-off valve, comprise valve body, valve rod and valve seat, valve body is provided with import and outlet, and valve seat is connected with valve body, valve body is provided with valve gap, valve gap is connected with valve rod, and the valve rod upper end is provided with handwheel, and the valve rod lower end is provided with valve disc, valve disc extend in the valve body and can form with valve seat and is tightly connected, described valve gap center is provided with stuffing hole, and the intermediate portion of valve rod is filled with stuffing box packing by stuffing hole between the hole wall of valve rod and stuffing hole; Be provided with gland above the described stuffing hole, gland is connected with valve gap by screw and fixes.
As optimal technical scheme of the present utility model, the axis of described valve body import is perpendicular to the axis of valve outlet.
As optimal technical scheme of the present utility model, described valve rod top is provided with screw thread, and described valve gap upper end is provided with thread bush, and valve rod is connected with valve gap by thread bush and can moves up and down along valve rod axis; Described valve gap lower end is provided with the filler seat, valve rod be located in the filler seat and can with filler seat relative sliding.
As optimal technical scheme of the present utility model, described valve disc is provided with gland nut, and valve disc is connected with the valve rod lower end by gland nut.
As optimal technical scheme of the present utility model, the flange at described valve body, valve gap and valve body two ends all is to be processed into by cast steel.
The beneficial effects of the utility model are: with respect to prior art, the utility model valve body and flange are processed into overall structure by cast steel, and intensity is higher; Fill stuffing box packing in the stuffing hole at valve gap center, valve disc and valve seat are adaptive and form good being tightly connected, and the thread bush of valve gap upper and lower end and filler toilet are in replacing.The utility model compact structure, good seal, long service life, easy to operate.
