Abstract
A rubber lining steering check valve mainly solves the problem that the conventional rubber lining steering check valve is difficult to line rubber in place. The rubber lining steering check valve provided by the utility model is characterized in that the lower bottom edge of a roller path is connected with the side wall of an upper valve body; a steel plate extends upwards from the upper bottom edge of the roller path; the width of the upper bottom edge of the steel plate is the same as the diameter of an outlet passage, and is connected with the outlet passage; wear-resistant anti-corrosion rubber is lined on the inner parts of the upper valve body, a lower valve body, the roller path and the steel plate. The rubber lining steering check valve has the advantage that rubber lining is convenient.
Description
Technical field
The utility model relates to a kind of safety check, is specifically related to a kind of line with rubber and turns to safety check.
Background technique
Safety check, also claim one-way valve, is widely used in fluid system, and the principal security fluid flows in a direction, prevents that fluid from refluxing.In order to improve sealability, on a lot of safety check inner sealing faces, all be lined with vulcanized rubber, but existing rubber liner check valve some place when line with rubber is not easy lining, put in place, thereby affect its impact of performance.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of line with rubber to turn to safety check, solves line with rubber and is not easy to serve as a contrast the problem put in place.
A kind of line with rubber turns to safety check, include upper valve body, lower valve body, described upper valve body is connected with lower valve body, described upper valve body is provided with outlet passage, described lower valve body is provided with two inlet passages, between described two inlet passages, an angle is arranged, in described upper and lower valve body, be provided with ball sealer, in described upper valve body, being provided with can be for the raceway of ball sealer activity, the diameter of described ball sealer is greater than the inlet passage diameter, described raceway bottom is connected with the upper valve body sidewall, the upper base of raceway has extended upward steel plate, described steel plate upper base hem width degree is identical with the diameter of outlet passage, and be connected with outlet passage, described upper and lower valve inner and raceway, steel plate all is lined with wear-and corrosion-resistant rubber.
The beneficial effects of the utility model are: adopt above scheme, avoided, to the line with rubber in outlet body wall corner, needing having an even surface of line with rubber, easily line with rubber puts in place.
The accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the utility model embodiment sectional drawing.
1-upper valve body in figure, 11-outlet passage, 12-raceway, 13-steel plate, valve body under 2-, 21-inlet passage, 3-ball sealer, 4-wear-and corrosion-resistant rubber.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figures 1 and 2, include upper valve body 1, lower valve body 2, described upper valve body 1 is connected with lower valve body 2, described upper valve body 1 is provided with outlet passage 11, described lower valve body 2 is provided with two inlet passages 21, between described two inlet passages 21, an angle is arranged, described upper and lower valve body 1, in 2, be provided with ball sealer 3, in described upper valve body 1, being provided with can be for the raceway 12 of ball sealer 3 activities, the diameter of described ball sealer 3 is greater than inlet passage 21 diameters, described raceway 12 bottoms are connected with upper valve body 1 sidewall, the upper base of raceway 12 has extended upward steel plate 13, described steel plate 13 upper base hem width degree are identical with the diameter of outlet passage 11, and be connected with outlet passage 11, described upper and lower valve body 1, 2 inner and raceways 12, steel plate 13 all is lined with wear-and corrosion-resistant rubber 4.
Adopt above scheme, avoided, to the line with rubber in outlet body wall corner, needing having an even surface of line with rubber, easily line with rubber puts in place, can strengthen simultaneously and be subjected to force intensity.
