Abstract
The invention relates to a threaded stop valve comprising a valve body, a valve clack and a valve rod. A through-hole nut at the bottom of the valve body is connected with a threaded valve clack at the bottom of the valve clack; the threaded valve clack is provided with a plurality of through holes; a layer of sealing rings is arranged in the middle of the valve clack; the valve clack is connected with the valve rod in a buckling way; the top end of the valve rod is provided with a hand wheel; the hand wheel is fixed on the top end of the valve rod through a hexagonal nut; a valve cover is arranged at the periphery of the valve rod; graphite filler is filled between the valve cover and the valve rod; the top end of the valve cover is provided with a graphite filler gland; a copper sleeve is arranged between the graphite filler gland and the valve rod; the valve body is fixedly connected with the valve cover through bolts; and a sealing gasket is arranged between the valve body and the valve cover. The threaded stop valve has the advantages of simple structure, convenient manufacturing, maintaining and installing, short staring time during working, good sealing performance, small friction force of sealing surfaces, long service life and wide application range.
Description
Technical field
The present invention relates to a kind of threaded stop valve.
Background technique
General stop valve lacks spiral shell flap and seal ring below flap, make space that valve body itself places towards having influence on sealing, has been with great inconvenience to use, and this is the reason that general stop valve must horizontal vertical just can be accomplished sealing.And this threaded stop valve has just solved the problem of this respect, and it can not influence sealing because of the direction of valve placement, and such design can be used more extensive.
Summary of the invention
The purpose of this invention is to provide a kind of threaded stop valve, have only horizontal vertical just can accomplish the narrow limitation of sealing to solve common stop valve.
The objective of the invention is to be achieved through the following technical solutions:
A kind of threaded stop valve, comprise valve body, flap and valve rod, the through hole nut of described valve body bottom is connected with the spiral shell flap of described flap bottom, the spiral shell flap is provided with some through holes, described flap middle part is provided with one deck seal ring, described flap and described valve rod are fastened and connected mutually, the top of described valve rod is provided with handwheel, handwheel is fixed in described valve stem tip by hexagon nut, the periphery of described valve rod is provided with valve gap, be filled with graphite packing between described valve gap and the described valve rod, described valve gap top is provided with Gland, be provided with copper sheathing between described Gland and the described valve rod, described valve body and described valve gap are bolted to connection, and are provided with sealing gasket between described valve body and the described valve gap.
Beneficial effect of the present invention is: simple in structure, make and keep in repair more convenient, and opening and closing time is short during work, good airproof performance, sealing surface frictional force is little, and the life-span is long, and is easy for installation again, applied widely.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the described threaded stop valve sectional view of the embodiment of the invention;
Fig. 2 is the sectional view of the flap of the described threaded stop valve of the embodiment of the invention;
