And valve is opened or closed, but such that part valve rod exposes in air because of rising, it is raw to will lead to part valve rod
Rust or corrosion, if constantly derusting or adding oil lubricating in moist working environment domestic demand.To solve this problem, this is practical new
Type proposes a kind of shut-off valve for being not easy to get rusty.
Utility model content
To overcome the problems of the prior art, the utility model proposes a kind of shut-off valve, including cut-off valve body, it is described
Cut-off valve body is mainly made of handwheel, gland, valve deck, valve rod, flap, valve body and sealing pair；The shut-off valve sheet
It is fixedly connected with handwheel at the top of body, handwheel is bolted mode and is fixedly connected with the top of valve rod；The cut-off valve body
Bottom is provided with valve body, and body top is provided with valve deck, and valve deck with valve neck by being fixedly connected；The valve rod is arranged in valve neck
In；Wherein, the valve rod includes the first valve rod and the second valve rod, and first valve rod center is equipped with negative thread, first valve
For bar in being connected in the valve neck by bearing, the upper end of second valve rod has the pin thread to match, second valve rod
It rotates and moves up and down in the valve neck, second stem bottom is fixedly connected with flap, and flap is connected to shut-off valve sheet
The opening in internal portion；The valve neck is internally provided with gland, and valve rod is threadedly coupled with gland, and valve neck is internally located at
Gland bottom is provided with sealing pair.
The utility model proposes the shut-off valve in, the cut-off valve body use straight-through structure.
The utility model proposes the shut-off valve in, the cut-off valve body is made of austenitic stainless steel.
The utility model proposes the shut-off valve in, the mode being bolted between the valve deck and valve neck is fixed
Connection.
The utility model proposes the shut-off valve in, the valve deck have draining board.
Compared with prior art, the utility model has the beneficial effects that the valve rod of the utility model is by the first valve rod and second
Valve rod composition, the first valve rod and the second valve rod are arranged in valve neck, are drawn between the first valve rod and the second valve rod there is only opposite
It is dynamic, it is both not exposed in outside air, prevents from being corroded or getting rusty in valve rod exposure air.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model shut-off valve.
Specific embodiment
Below in conjunction with schematic diagram to the utility model proposes be described in more detail, it is practical new which show this
The preferred embodiment of type, it should be appreciated that those skilled in the art can modify the utility model described herein, and still realize
The advantageous effects of the utility model.Therefore, following description should be understood as the widely known of those skilled in the art, and
It is not intended as limitations of the present invention.
Referring to Fig. 1, a kind of shut-off valve, including cut-off valve body, which is characterized in that cut-off valve body is mainly by handwheel
1, gland 2, valve deck 3, valve rod 4, flap 5, valve body 6 and sealing pair 7 are constituted；Shut-off valve bodies top is fixedly connected with handwheel
1, handwheel 1 is bolted mode and is fixedly connected with the top of valve rod 4；Shut-off valve body bottom portion is provided with valve body 6, valve body 6
Top is provided with valve deck 3, and valve deck 3 with valve neck 8 by being fixedly connected；Valve rod 4 is arranged in valve neck 8；Wherein, valve rod 4 includes the
One valve rod 41 and the second valve rod 42, the center of the first valve rod 41 are equipped with negative thread, and the first valve rod 41 is in passing through bearing company in valve neck 8
It connecing, the upper end of the second valve rod 42 has the pin thread to match, and the second valve rod 42 is rotated and moved up and down in valve neck 8, and second
4 bottom of valve rod is fixedly connected with flap 5, and flap 5 is connected to the opening of cut-off valve body；Valve neck 8, which is internally provided with, to be filled out
Expect that gland 2, valve rod 4 are threadedly coupled with gland 2, valve neck 8 is internally located at 2 bottom of gland and is provided with sealing pair 7.Cut-off
