Abstract
The utility model discloses a ball-shaped check valve, which comprises a valve body, a valve corer and a valve flap. The utility model has the different points that the valve flap adopts a ball shape, a guiding rod is arranged at the inner side of the fluid body inlet of the valve body, the valve flap is arranged in the guiding rod and is matched with the guiding rod, and a stop lever is arranged at the inner side of the fluid body outlet opening of the valve body. The check valve has the advantages that the sealing performance is good, the check valve is secure and reliable, the service life is long, and real time adjustment can be performed according to the flow quantity of medium.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to the safety check of controlling and regulate media flow on a kind of chemical industry pipeline.
Background technique
At present, China's chemical industry is used for the safety check of gas flow control closes or Open valve by the displacement of handwheel rotary valve rod drive flap mostly, and this kind safety check can not carry out real-time regulated, complex operation with the flow of medium, and liner easily comes off, fragile, produce and leak, even security incident takes place, valve is short working life, change frequently, influence is produced, and causes economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of novel structure, and good seal performance can be carried out real-time regulated according to the flow of medium, and is easy to operate, the ball check valve of long service life.
The technical scheme in the invention for solving the technical problem is: a kind of ball check valve, it comprises valve body, valve gap, flap, difference is, above-mentioned flap is a spheroid, above-mentioned valve body fluid import inboard is equipped with guide rod, above-mentioned flap places in the above-mentioned guide rod and with guide rod and matches, and above-mentioned valve body fluid outlet inboard is equipped with lever.
The downside of above-mentioned valve body is equipped with the valve body visor.
Be equipped with the valve gap visor on the above-mentioned valve gap.
Above-mentioned lever is " U " shape.
Be equipped with buffer layer on above-mentioned lever, the guide rod.
The utility model compared with prior art has following advantage:
The valve body fluid of this ball check valve outlet inboard is equipped with lever, makes flap be difficult for snapping in the valve outlet, and is equipped with buffer layer on the lever, guide rod, reduces the wearing and tearing of flap outer surface; Can carry out real-time regulated according to the flow of medium, easy to operate, the weight by spheroid self seals good seal performance, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model ball check valve.
Embodiment
Below in conjunction with accompanying drawing the utility model ball check valve is further described.
As shown in Figure 1, a kind of ball check valve, it comprises valve body 1, valve gap 2, flap 3, difference is, above-mentioned flap 3 is a spheroid, is equipped with three guide rods 11 on the above-mentioned valve body 1, and is evenly distributed on valve body fluid import inboard, above-mentioned flap 3 places in the above-mentioned guide rod 11 and with guide rod 11 and matches, and above-mentioned valve body 1 fluid output inboard is equipped with " U " shape lever 12; The downside of above-mentioned valve body 1 is equipped with valve body visor 41; Be equipped with valve gap visor 42 on the above-mentioned valve gap 2; Be equipped with buffer layer 111,121 on above-mentioned lever, the guide rod.
During use, valve body 1 is vertically mounted in the pipeline, when media flow flowed from bottom to top, flap 3 was to top offset, valve open, when media flow stops, rely on the deadweight of flap 3, to bottom offset, valve closing, can pass through valve body visor 41, valve gap visor 42 observation spheroid positions, thereby regulate the flow size.
