Description
Technical field
The present invention relates to a kind of water seal shut-off valve.
Background technology
The opening and closing element of shut-off valve is the flap of stopper, and sealing is above in plane or the extra large conical surface, center line of the flap along valve seat
It is for linear motion.The forms of motion of valve rod, also has lifting rotation rod-type to can be used for the empty gas and water of control, steam, various corrosivity to be situated between
The flowing of all kinds fluid such as matter, mud, oil product, liquid metal and radiating medium.Therefore, such cut-off of shutting off
Valve valve is highly suitable as cutting off or the use that adjusts and throttle.Since the valve rod of such valve is turned on and off stroke relatively
It is short, and there is very reliable cutting function, and the change due to valve seat port and the stroke direct proportionality of flap, it is non-
It is very suitable for the adjusting to flow.The shut-off valve generally used in the industry at present is sealed using sealing ring more, and sealing ring is in valve
It can be worn under the friction repeatedly of bar, and then influence the leakproofness of shut-off valve.
The content of the invention
The present invention mainly solves the technical problem present in the prior art, so as to provide a kind of water seal shut-off valve.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of water seal shut-off valve, comprising a valve body, the bottom of valve body is equipped with a base, and valve body is equipped with a pair of of fluid interface, valve
Body is equipped with a stent, is equipped with a valve rod in stent, is socketed a driving wheel on the body of rod of valve rod, a pair of of cunning is additionally provided with stent
Wheel, the top of stent connect a water seal cylinder, extend to water seal cylinder interior at the top of valve rod, the head cover of water seal cylinder can be opened, water seal
The side of cylinder is equipped with a pair of of fixinig plate, and a fastening nut is respectively provided with fixinig plate.
As preferred embodiments of the present invention, the valve rod and driving wheel are integrally formed.
As preferred embodiments of the present invention, the casing wall of the water seal cylinder is double-decker.
The water seal shut-off valve of the present invention is provided with a stent on body, and valve rod is located at the inside of stent, the valve rod body of rod
The driving wheel of upper setting is used to connect external drive equipment, and the top of stent is provided with a water seal cylinder, the top extension of valve rod
To water seal cylinder, so valve rod is sealed by the water in water seal cylinder, water body will not influence leakproofness because of friction, this
The job stability of sample shut-off valve is stronger.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
