Abstract
The utility model relates to a three-way post spin valve which comprises a valve body, a post piston, a polyfluortetraethylene layer and a valve cover, wherein the polyfluortetraethylene layer is fixed on the inner wall of the valve body, and the post piston is arranged in the valve body and is tightly sealed with the polyfluortetraethylene layer fixed into the valve body to form a sealing surface. The top end of the valve cover is screwed with a regulating screw, and the seal between the post piston and the polyfluortetraethylene layer in the valve body is tightly pressed by the screw through a sealing pressing cover. Flanges which are connected with a pipeline are arranged on the outer ends of three medium through holes on the valve body, and outer end holes of the three medium through holes are provided with internal threads which are directly connected with screw threads of the pipeline. The three-way post spin valve can flexibly open and close the valve and has the advantages of free rotation, convenient and reliable operation, good sealing performance and long service life.
Description
Technical field
The utility model relates to valve, particularly relates to the three through post stopcocks that use on the metallurgy high furnace cool cycles water piping system.
Background technique
At present, iron and steel enterprise's metallurgical furnace, as the tee ball valve that uses on the blast furnace cool cycles water piping system, interior and the valve ball of its valve body, the perhaps sealing surface that matches with stopper of the valve interior wall of threeway plug valve, generally all be to adopt hard sealing structure, the cooling water system on the blast furnace furnace wall is in running order for a long time, because of valve be subjected to the hot water or cold water wash away etch and cold shrinkage and thermal expansion is out of shape.When cooling water system breaks down or leaks, need to close, when driving valve, because the valve ball of ball valve or the stopper of stopcock and valve interior wall chucking, throttle down quickly and effectively, otherwise the valve opening of closing is ineffective, need beat valve ball or unclamp the fixedly nut of stopper, therefore prolong the time of giving, cutting off the water, make and rush to repair the untimely production that influenced again in the stopcock bottom.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of good airproof performance, and the open and close valve is flexible, convenient and reliable operation, three through post stopcocks of long service life.
The technological scheme that adopts is:
Three through post stopcocks comprise valve body, plunger, polytetrafluoroethylene floor and valve gap.Described polytetrafluoroethylene floor is fixed on the inwall of valve body, and plunger is contained in the valve body, and with the polytetrafluoroethylene floor deadend that is fixed in the valve body, constitute sealing surface.
The adjustment screw has been screwed on above-mentioned valve gap top, adjusts screw and compresses the sealing between the polytetrafluoroethylene floor in plunger and the valve body by sealing gland.
Three medium through hole outer ends are equipped with and pipeline flange connecting dish on the above-mentioned valve body.
Three medium through hole external port all are set as the internal thread that directly is threaded with pipeline on the above-mentioned valve body.
The utility model open and close valve is flexible, rotates freely convenient and reliable operation, good seal performance, long service life.
Description of drawings
Fig. 1 is the utility model embodiment one a structural representation.
Fig. 2 is the utility model embodiment two a structural representation.
Embodiment
Three through post stopcocks comprise valve body 1, plunger 2, polytetrafluoroethylene floor 3 and valve gap 7.Described polytetrafluoroethylene floor 3 is fixed on the inwall of valve body 1 through hot pressing, plunger 2 is contained in the valve body 1, and with polytetrafluoroethylene floor 3 deadends that are fixed in the valve body, constitute sealing surface, its the two seal degree is screwed and is adjusted screw 8 on the valve gap 7, and by sealing degree of tightness between the polytetrafluoroethylene floor 3 in sealing gland 6 adjustment plungers 2 and the valve body 1.Three medium through hole 5 outer ends are equipped with and pipeline flange connecting dish 4 on the valve body 1, constitute three through post stopcocks.
Embodiment two
Embodiment two and embodiment one are basic identical, and difference is that three medium through hole 5 external port all are set as the internal thread that directly is threaded with pipeline on the described valve body 1, and other is identical with embodiment one.
