Abstract
The utility model discloses a fluoroplastic full-lining diaphragm valve special for alkali-chloride composed of a valve body (1), a valve cap assembly (2), a valve spindle (3), a hand wheel (4) and a pressing block (5). A sealed lining (6) is equipped in the valve body (1). The utility model is characterized in that the lower part of the pressing block (5) is equipped with a diaphragm cushion (7); the lower part of the diaphragm cushion (7) is equipped with a diaphragm sheet (8); the bottom of the valve body (1) is in a convexity body (11); the diaphragm sheet (8) and the convexity body (11) are abutted; the inner wall of the valve body (1) is equipped with a groove (12); the sealed lining (6) is filtered in the groove (12). The diaphragm valve has the advantages of good sealing property, good corrosion proof, safety, reliability and long service life.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of fluoroplastics full-lining diaphragm valve that controlling liquid flows on the chemical industry deep-etching pipeline that is used for.
Background technique
At present, chemical industry is used for the valve that controlling liquid flows on the deep-etching pipeline and is common lined valve or overall plastic valve, and common lined valve inner seal liner does not serve as a contrast entirely in valve body even adopts common lining material, lining is bonding insecure, easily come off, simultaneously common lining material corrosion resistant performance is poor, is used for that controlling liquid flows on the chlor-alkali pipeline, fragile, produce and leak, valve is short working life, changes frequent, influence Chemical Manufacture, cause economic loss; Overall plastic valve during use, because the pressure reduction of pipeline internal medium is concentrated pipe bending stress, easily causes the adpting flange fracture of valve because whole valve is an all-plastic, produces and leaks, even security incident takes place.
Summary of the invention
The purpose of this utility model is to provide a kind of alkali-chloride special-purpose fluoroplastic all-liner membrane valve, and it has the better seal performance, and is corrosion-resistant, safe and reliable, long service life.
The utility model is to solve the problems of the technologies described above to realize by following technical proposal, above-mentioned alkali-chloride special-purpose fluoroplastic all-liner membrane valve, comprise valve body, valve gap assembly, valve rod, handwheel, briquetting, above-mentioned valve body is built-in with sealed liner, and difference is, above-mentioned briquetting below is equipped with the barrier film pad, above-mentioned barrier film pad below is equipped with diaphragm, and above-mentioned valve body bottom is convex body, above-mentioned diaphragm and above-mentioned convex body apical grafting, be equipped with groove on the above-mentioned valve interior wall, above-mentioned sealed liner infiltrates in the above-mentioned groove.
Above-mentioned groove width of rebate is not more than the bottom land width.
Above-mentioned sealed liner is fluoroplastic.
The utility model alkali-chloride special-purpose fluoroplastic all-liner membrane valve compared with prior art has following advantage:
1, the valve interior wall of this valve is equipped with groove, and sealed liner is infiltrated in the groove, and it is firm that sealed liner is connected with valve body, and good seal performance is safe and reliable, is difficult for producing and leaks.
2, this valve seal liner adopts polyfluorinated ethylene plastic, and corrosion resistance is strong, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model fluoroplastics full-lining diaphragm valve;
Embodiment
As shown in Figure 1, described alkali-chloride special-purpose fluoroplastic all-liner membrane valve, comprise valve body 1, valve gap assembly 2, valve rod 3, handwheel 4, briquetting 5, above-mentioned valve body 1 is built-in with sealed liner 6, and difference is, above-mentioned briquetting 5 belows are equipped with barrier film pad 7, above-mentioned barrier film pad 7 belows are equipped with diaphragm 8, and above-mentioned valve body 1 bottom is convex body 11, above-mentioned diaphragm 8 and above-mentioned convex body 11 apical graftings, be equipped with groove 12 on above-mentioned valve body 1 inwall, above-mentioned sealed liner 6 infiltrates in the above-mentioned groove 12.Above-mentioned groove 12 width of rebate are not more than the bottom land width.Above-mentioned sealed liner 6 is fluoroplastic.
During use, handwheel 4 rotations, drive valve rod 3 upper and lower displacements, barrier film pad 7 and diaphragm 8 upper and lower displacements simultaneously, when to top offset, diaphragm 8 separates with the convex body 11 of above-mentioned valve body 1 bottom, valve open, when to bottom offset, convex body 11 apical graftings of diaphragm 8 and above-mentioned valve body 1 bottom, valve closing.
Claims (3)
1, a kind of alkali-chloride special-purpose fluoroplastic all-liner membrane valve, comprise valve body (1), valve gap assembly (2), valve rod (3), handwheel (4), briquetting (5), above-mentioned valve body (1) is built-in with sealed liner (6), it is characterized in that: above-mentioned briquetting (5) below is equipped with barrier film pad (7), above-mentioned barrier film pad (7) below is equipped with diaphragm (8), above-mentioned valve body (1) bottom is convex body (11), above-mentioned diaphragm (8) and above-mentioned convex body (11) apical grafting, be equipped with groove (12) on above-mentioned valve body (1) inwall, above-mentioned sealed liner (6) infiltrates in the above-mentioned groove (12).
