Description

A kind of water seal shut-off valve
Technical field
The utility model is related to a kind of water seal shut-off valves.
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 controlling empty gas and water, steam, various corrosivity and is situated between The flowing of the various types 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 adjusting and throttling is used.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 due to the stroke direct proportionality of the variation of valve seat port and flap, it is non- It is very suitable for the adjusting to flow.The shut-off valve generally used in the industry at present mostly uses sealing ring and is sealed, 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.
Utility model content
The utility model is mainly the technical problem solved present in the prior art, to provide a kind of water seal shut-off valve.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals:
A kind of water seal shut-off valve, including a valve body, the bottom of valve body is equipped with a pedestal, and valve body is equipped with a pair of of fluid and connects Mouthful, valve body is equipped with a holder, and a valve rod is equipped in holder, a driving wheel is socketed on the body of rod of valve rod, one is additionally provided on holder To pulley, the top of holder connects a water seal cylinder, and water seal cylinder interior is extended at the top of valve rod, and the head cover of water seal cylinder can be opened, The side of water seal cylinder is equipped with a pair of of fixinig plate, and a fastening nut is respectively provided on fixinig plate.
As the utility model preferred embodiment, the valve rod and driving wheel are integrally formed.
As the utility model preferred embodiment, the casing wall of the water seal cylinder is double-layer structure.
The water seal shut-off valve of the utility model is provided with a holder on the body, and valve rod is located at the inside of holder, valve rod The driving wheel being arranged on the body of rod is provided with a water seal cylinder, the top of valve rod for connecting external drive equipment, the top of holder It extends in water seal cylinder, valve rod is sealed by the water in water seal cylinder in this way, water body will not influence to seal because of friction Property, the job stability of such shut-off valve is stronger.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the dimensional structure diagram of the water seal shut-off valve of the utility model.
Specific implementation mode
