The flange type angle shut-off valve comprises a valve body, a valve rod and a valve seat, wherein the valve body is provided with an inlet and an outlet, the valve seat is connected with the valve body, the valve body is provided with a valve deck, the valve deck is connected with the valve rod, a hand wheel is arranged at the upper end of the valve rod, a valve disc is arranged at the lower end of the valve rod, extends into the valve body and is connected with the valve seat in a sealing mode, a padding hole is formed in the center of the valve deck, the middle part of the valve rod penetrates through the padding hole, the space between the valve rod and the hole wall of the padding hole is filled with sealing padding, a gland is arranged on the padding hole and is fixedly connected with the valve deck through a screw, and the axis of the inlet of the valve body is perpendicular to the axis of the outlet of the valve body. According to the flange type angle shut-off valve, the valve body and a flange are machined into an integrated structure in a steel casting mode, and the strength is high. The padding hole in the center of the valve deck is filled with the sealing padding, the valve disc and the valve seat are matched with each other and form good sealing connection, and a threaded sleeve and a padding seat at the upper end and the lower end of the valve deck are convenient to replace. The flange type angle shut-off valve is compact in structure, good in sealing, long in service life and convenient to operate.
Description
Technical field
The present invention relates to valve, 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 is generally common cock-type or flat stifled formula structure, and material is mainly cast iron, and existing stop valve exists valve mechanism complicated conventionally, and intensity is not high, not wear-resistant, easy to leak, the shortcoming such as working life is short.Existing cast steel stop valve is because working ability is limit, and its structure is comparatively simple, sealing is affected, and the replacing of the easily damaged parts of stop valve is convenient not.
Summary of the invention
The object of this invention is to provide a kind of good seal, be convenient to change easily damaged parts, and working life longer flange-type angle shut-off valve.
The object of the invention is by realizing by the following technical solutions:
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 valve rod upper end is provided with handwheel, and valve rod lower end is provided with valve disc, valve disc extend in valve body and can form and be tightly connected with valve seat, described valve gap center is provided with stuffing hole, and the intermediate portion of valve rod, by stuffing hole, is filled with stuffing box packing between valve rod and the hole wall of stuffing hole; Above described stuffing hole, be provided with gland, gland is connected with valve gap by screw and fixes.
As the preferred technical solution of the present invention, the axis of described valve body import is perpendicular to the axis of valve outlet.
As the preferred technical solution of the present invention, 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 filler seat, valve rod be located in filler seat and can with filler seat relative sliding.
As the preferred technical solution of the present invention, described valve disc is provided with gland nut, and valve disc is connected with valve rod lower end by gland nut.
As the preferred technical solution of the present invention, the flange at described valve body, valve gap and valve body two ends is to be all processed into by cast steel.
The invention has the beneficial effects as follows: with respect to prior art, valve body of the present invention and flange are processed into overall structure by cast steel, and intensity is higher; In the stuffing hole at valve gap center, fill stuffing box packing, 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.Compact structure of the present invention, good seal, long service life, easy to operate.
