Abstract
The invention discloses an erosion resistant spherical check valve which comprises a valve body, a valve cover, a valve flap and is characterized in that the valve flap is a sphere; a guide rod is arranged on the valve body; the valve flap is arranged in the guide rod and matched with the guide rod; a retaining rod is arranged on the inner side of the flow outlet of the valve body. The erosion resistant spherical check valve has the advantages of good seal performance, erosion resistance, safety, reliability, long service life and being adjusted according the flow rate of the medium real-timely.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to the safety check of controlling and regulate media flow on a kind of chemical industry pipeline.
Background technique
At present, the valve that China's chemical industry is used for deep-etching flowing medium control mostly is the plain cast iron valve of no liner or part liner greatly, and it is mobile to be used on the chlor-alkali pipeline controlling liquid, and corrosivity is big, 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; Common safety check drives the flap upper and lower displacement by the handwheel rotary valve rod mostly and cuts out or Open valve, and this kind safety check can not carry out real-time regulated, complex operation with the flow of medium.
Summary of the invention
The object of the present invention is to provide a kind of novel structure, corrosion-resistant, can carry out real-time regulated according to the flow of medium, operating aspect, the corrosion-resistant ball check valve of long service life.
The technological scheme that the present invention solves its technical problem is: a kind of corrosion-resistant 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 the outer surface of above-mentioned guide rod is covered with anticorrosive coat, and above-mentioned valve body fluid outlet inboard is equipped with lever.
The internal surface of above-mentioned valve body, valve gap and terminal area all are covered with anticorrosive coat, and the outer surface of above-mentioned flap is covered with anticorrosive coat, and the outer surface of above-mentioned lever is covered with anticorrosive coat.
The internal surface of above-mentioned valve body, valve gap and terminal area all are equipped with groove, and above-mentioned anticorrosive coat infiltrates in the groove.
The width of rebate of above-mentioned groove is not more than the bottom land width.
Above-mentioned lever is " U " shape.
Above-mentioned anticorrosive coat is fluoroplastic.
The present invention compared with prior art has following advantage:
1, the internal surface of the valve body of this corrosion-resistant ball check valve, valve gap and terminal area all are covered with anticorrosive coat, and the anticorrosive coat fixation comes off, corrosion resistance and good, long service life.
2, the anticorrosive coat of this corrosion-resistant ball check valve is teflon, and is corrosion-resistant, not yielding, good seal performance, long service life.
3, the valve body fluid of this corrosion-resistant ball check valve outlet inboard is equipped with lever, makes flap be difficult for snapping in the valve outlet, reduces the wearing and tearing of flap outer surface; Can carry out real-time regulated according to the flow of medium, easy to operate.
Description of drawings
Fig. 1 is the structural representation of corrosion-resistant ball check valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing corrosion-resistant ball check valve of the present invention is further described.
As shown in Figure 1, a kind of corrosion-resistant ball check valve, it comprises valve body 1, valve gap 2, flap 3, difference is, above-mentioned flap 3 flaps are spheroid, be equipped with guide rod 11 on the above-mentioned valve body 1, 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 internal surface of above-mentioned valve body 1, valve gap 2 and terminal area all are covered with anticorrosive coat 41,42, and the outer surface of above-mentioned flap 3 is covered with anticorrosive coat 43, and the outer surface of above-mentioned guide rod is covered with anticorrosive coat 111, and the outer surface of above-mentioned lever 12 is covered with anticorrosive coat 121; The internal surface of above-mentioned valve body 1, valve gap 2 and terminal area all are equipped with groove 51,52, and above-mentioned anticorrosive coat 41,42 infiltrates respectively in the groove 51,52; The width of rebate of above-mentioned groove 51,52 is not more than the bottom land width; Above-mentioned anticorrosive coat 41,42,43,111,121 is fluoroplastic.
During use, valve body 1 water is vertically mounted in the pipeline, and when media flow flowed from bottom to top, flap 3 was to top offset, and valve open when media flow stops, relying on the deadweight of flap 3, to bottom offset, and valve closing.
