Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of ceramic awl plug valve, comprise valve body 1, the middle part of described valve body 1 is provided with the through fluid passage in left and right 2, the inwall of fluid passage 2 is provided with latus rectum stoneware pipe 3, the top of valve body 1 is provided with and extends downwards and the cone shape hole 4 through with latus rectum stoneware pipe 3, conic ceramic plug 5 is provided with in cone shape hole 4, the sidewall of conic ceramic plug 5 is laterally provided with flowing hole 6, valve gap 8 is fixed by valve gap bolt 7 in the top of cone shape hole 4, the valve rod 9 be fixedly connected with conic ceramic plug 5 is interspersed with in the middle part of the top end of valve gap 8, the top connecting handle 10 of valve rod 9, the outer wall of valve rod 9 is arranged with the hollow bolt 11 be connected with valve gap 8 by screw thread, valve rod 9 outer wall of hollow bolt 11 bottom part down is arranged with spring 12, the bottom of spring 12 is resisted against on the top end of conic ceramic plug 5, the top of spring 12 is resisted against on the bottom end of hollow bolt 11.
Ceramic awl plug valve of the present utility model, the top outer wall of described conic ceramic plug 5 is arranged with metal cranse 13, and metal cranse 13 is used for ensureing that conic ceramic plug 5 can not by squeeze crack, also be the working life in order to extend conic ceramic plug 5 when rotating by valve rod 9.
Ceramic awl plug valve of the present utility model, is provided with square groove in the middle part of the top end of described conic ceramic plug 5, and the bottom of valve rod 9 is provided with the square spigot 14 be fixed in square groove.
Ceramic awl plug valve of the present utility model, is lined with asbestos packing 15 under the bottom end of described valve gap 8.
Ceramic awl plug valve of the present utility model, described hollow bolt 11 is sealed by seal ring 16 with the contacting point of valve rod 9.
Ceramic awl plug valve of the present utility model is when specifically using, because conic ceramic plug and latus rectum stoneware pipe are ceramic components, so have wearing and tearing after a long time use, when after wearing and tearing, these two-part there will be poorly sealed phenomenon, therefore this valve installs a spring on the top of conic ceramic plug, the hollow bolt that one adjustable is had on the top of spring, be threaded connection between hollow bolt and valve gap, when there is poorly sealed phenomenon in conic ceramic plug and latus rectum stoneware pipe, downward adjustment hollow bolt, it is always downward that spring is used for extruding taper ceramic plug, conic ceramic plug and latus rectum stoneware pipe is made to keep sealing state, the two-part latus rectum of latus rectum stoneware pipe is equally large with the flowing hole latus rectum of conic ceramic plug.When three latus rectums are consistent, valve is for opening, and when the latus rectum of conic ceramic plug is not consistent with the latus rectum of latus rectum stoneware pipe, valve is for close.Therefore, this valve on pipeline without installation direction.The material of valve body and valve gap can be cast iron, spheroidal graphite cast iron, casting steel or stainless steel, and Connecting format is that screwed flange connects.Applicable nominal pressure is 0.25MPa-40MPa.Under this valve is particularly useful for the operating mode of high temperature, high pressure, strong alkali-acid resistance, dust or have short grained medium.This valve is lightweight, easy for installation.The ceramic fitting of super thick can make increase 2-5 doubly than common valve the working life of valve, and the ceramic fitting of this valve can also be changed after damage, simple to operate, thus has saved cost.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
