Abstract
The utility model discloses a quick opening exhaust valve, comprising a valve body; a valve inlet is communicated with the upper part of the left side of the valve body; a valve outlet is communicated with the bottom of the valve body; the inner wall of the bottom of the valve body is molded to be a conical part; the upper part of the inner cavity of the valve outlet is expanded relative to the lower part of the inner cavity of the valve outlet. A ring plate is arranged at the part, positioned below the height of the valve inlet, at the inner wall of the valve body; a valve rod is vertically and glidingly arranged at the top of the valve body; the bottom end of the valve rod extends below the ring plate and is connected with a valve plate; the shape of the valve plate is matched with that of the conical part of the bottom of the valve body; multiple through holes are formed in the valve plate and a plug is arranged at the center of the bottom of the valve plate. The block valve can fast realize the blocking function and the performances of the block valve are improved.
Description
Technical field
The utility model relates to block valve field, is specially a kind of fast block valve.
Background technique
Block valve claims again cut-off valve, and its effect is the flowing medium that blocks or connect in pipeline.The block valve of prior art, in the time turn-offing, is vulnerable to the effect of valve fluid pressure, causes the slow problem of turn-off speed.
Model utility content
The purpose of this utility model is to provide a kind of fast block valve, to solve the slow problem of prior art block valve turn-off speed.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of fast block valve, include valve body, valve body left upper portion is communicated with into valve port, valve body bottom is communicated with out valve port, it is characterized in that: described valve body bottom interior wall is shaped to the tapered portion upwards arching upward, described go out valve port inner chamber top extend to and connect valve body bottom tapered portion, and go out valve port inner chamber top with respect to going out the bottom hole enlargement of valve port inner chamber, described valve interior wall is positioned at into valve port height below and is provided with ring flat-plate, valve body top is vertically slidably fitted with valve rod, described valve rod bottom is stretched in the valve body below ring flat-plate, and valve rod bottom is connected with the valve plate cutting off in valve body, described valve plate shape and valve body bottom tapered portion form fit, valve plate sidewall and valve interior wall close contact, in described valve plate, be provided with multiple through holes, valve plate bottom centre is provided with and the plug that goes out valve port inner chamber shaped upper part and mate.
Described a kind of fast block valve, is characterized in that: described valve plate sidewall is provided with seal ring.
In the utility model, fluid enters in valve body from entering valve port, flow into out valve port by through hole on valve plate, need to turn-off pressure valve bar at present, valve plate is subject to top fluid pressure action simultaneously, can realize valve plate and hurtle down, thereby cover in the tapered portion of valve body bottom, through hole be blocked, the plug of valve plate bottom also shutoff going out in valve port inner chamber top.The utility model can be realized break-in facility fast, has improved the performance of block valve.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
