Abstract
The utility model provides a dark pole stop valve, drives the rotation of valve rod through rotating the hand wheel, and the rotation is only done to the valve rod, does not do the up -and -down motion, and the valve rod passes through the trapezoidal thread to be connected with valve -stem nut on the valve clack, and the direction muscle that the valve clack passes through on the valve body is fixed, only does the up -and -down motion, does not do the rotation, when the valve rod rotates, does the up -and -down motion through trapezoidal thread drive valve clack. A valve rod pivoted is talked about, increases the sealing reliability of the filler between valve rod and the valve body, has guaranteed the sealing performance of valve.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of rising stem stop valve.
Background technique
In prior art, conventional stop valve by rotating the rotation of handwheel band ovable valve stem, thus drives flap to rotate to rise, but should rotate due to valve rod, move up and down again, thus cause the sealability of the filler between valve rod and valve body greatly to decline.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of rising stem stop valve.
The technical solution that the utility model adopts is: a kind of rising stem stop valve, comprise valve body, flap, valve rod and handwheel, described valve body is provided with valve gap, described valve gap is bolted on valve body, described flap is arranged on valve stem tip, also Stem Mut is provided with between described flap and valve rod, described flap is fixed on flap by Stem Mut, described Stem Mut is threaded with between valve rod, described flap is provided with the guiding groove of vertical direction, described valve body is provided with the vertical guiding rib coordinated with guiding groove, and the slippage spacing with guiding rib of described guiding groove coordinates.
Described Stem Mut is connected by trapezoidal thread with between valve rod.
Described flap is provided with mounting groove, and described Stem Mut is connected in mounting groove.
Also be provided with the chute for the upper and lower slippage of valve rod bottom described mounting groove, described valve stem top coordinates with slippage between chute.
Described valve gap top is also provided with support, and described support is provided with packing cavity, is provided with filler in described packing cavity, and described packing cavity is also provided with gland, and described gland is also provided with pressing plate, and described pressing plate is bolted on support.
The beneficial effects of the utility model are: the utility model provides a kind of rising stem stop valve, by rotating the rotation of handwheel band ovable valve stem, valve rod only rotates, do not move up and down, valve rod is connected with the Stem Mut on flap by trapezoidal thread, and flap is fixed by the guiding rib on valve body, only move up and down, do not rotate, when valve rod rotates, drive flap to move up and down by trapezoidal thread.Valve rod only rotates, and increases the sealing reliability of the filler between valve rod and valve body, ensure that the sealability of valve.
