Abstract
The utility model relates to an inner-bag mouth sealing device of a water-storage type electric water heater, which comprises a flange ring (1), a flange glass (2), a screw bolt (3), a sealing ring (4) and a core sleeve (5), wherein the sealing ring (4) is tightly sheathed outside the core sleeve (5) and forms a cone shape. An inner-bag mouth (6) forms an inverted cone shape, and the core sleeve (5) with the sealing ring (4) is blocked on the inner-bag mouth (6). The outer surface of the sealing ring (4) closely contacts the inner surface of the inner-bag mouth (6), and the upper surface of the core sleeve (5) is tightly pressed by the flange ring (1). The utility model has the advantages of good sealing property, easy control of product quality, high qualification rate and less possibility of water leakage and electrical leakage.
Description
The utility model relates to storage-type electric water heater inner-tube mouth seal arrangement.
At present, the structure of the storage-type electric water heater inner-tube mouth seal arrangement on the market as shown in Figure 1, it is to be used as seal element by an annular as glue seal ring A, utilize bolt B, flange circle C to compress the effect that rubber seal A reaches sealing, as Fig. 2, shown in Figure 3, seal ring is because uneven stressed all around, be that F1 and F2 among Fig. 2 is unequal, therefore irregular distortion takes place, cause sealing effect bad, the situation that generation is leaked, thus may cause the circuit board of inner-tube mouth outside to break down or produce the situation of electric leakage.The seal arrangement of now this inner-tube mouth cause reject rate higher, the common product up-to-standard rate has only about 70%, quality of product is restive.
The purpose of this utility model provides a kind of storage-type electric water heater inner-tube mouth seal arrangement.It passes through to change the shape of inner-tube mouth and the shape of seal ring with matching, thereby reaches better sealing effect, improves security of products, makes the up-to-standard rate height of product.
The utility model is realized by following technological scheme: it comprises flange circle, flange cup, bolt and seal ring, it comprises core retainer plate in addition, seal ring is locked in the outside of core retainer plate, seal ring is tapered, and inner-tube mouth is inverted cone, and the core retainer plate that has seal ring gets lodged on the inner-tube mouth, the outer surface of seal ring closely contacts with the internal surface of inner-tube mouth, the upper surface of core retainer plate is compressed by the flange circle, and the flange circle is installed in the flange cup by bolt, and the flange cup is fixed on the outside of inner-tube mouth.
Scope 0 degree of the tilt angle alpha of above-mentioned described inner-tube mouth is between 90 degree.
Stretch out curved down flange and form groove at the top place of above-mentioned described core retainer plate, and the top of seal ring embeds the groove the inside.
The utility model compared with prior art has following advantage: good airproof performance, because inner-tube mouth causes inverted cone, seal ring causes taper, and is stressed comparatively even, is close to the energy inner-tube mouth after the distortion, and potted line is longer, the specific pressure of bearing is bigger, so sealing effect is very good, the easier control of the quality of product, the up-to-standard rate height is not easy to produce the situation of leaking and leaking electricity.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is traditional storage-type electric water heater inner-tube mouth schematic diagram of sealing device;
Fig. 2 is the force analysis figure of traditional seal ring;
Fig. 3 is the distortion that traditional seal ring discontinuity produces;
Fig. 4 is a kind of structure erection drawing of the present utility model;
Fig. 5 is the plan view of Fig. 4;
Fig. 6 is the structure erection drawing after the utility model improves.
As Fig. 4, shown in Figure 5, the utility model comprises flange circle (1), flange cup (2), bolt (3) and seal ring (4), it comprises core retainer plate (5) in addition, seal ring (4) is locked in the outside of core retainer plate (5), seal ring (4) is tapered, inner-tube mouth (6) is inverted cone, the core retainer plate (5) that has seal ring (4) gets lodged on the inner-tube mouth (6), the outer surface of seal ring (4) closely contacts with the internal surface of inner-tube mouth (6), the upper surface of core retainer plate (5) is compressed by flange circle (1), flange circle (1) is installed in flange cup (2) by bolt (3), and flange cup (2) is fixed on the outside of inner-tube mouth.Scope 0 degree of the tilt angle alpha of inner-tube mouth (6) is between 90 degree.The move left and right that prevents core retainer plate (5) in addition can be welded on core retainer plate (5) top on the flange circle (2).
As shown in Figure 6, stretch out curved down flange (7) and form groove (8) at the top place of core retainer plate (5), and the top of seal ring (4) embeds groove (8) the inside, has so increased the length of core retainer plate (5) with the potted line of seal ring (4), and sealing effect is better.
Claims (3)
1, storage-type electric water heater inner-tube mouth seal arrangement, comprise flange circle (1), flange cup (2), bolt (3) and seal ring (4), it is characterized in that it comprises core retainer plate (5), seal ring (4) is locked in the outside of core retainer plate (5), seal ring (4) is tapered, inner-tube mouth (6) is inverted cone, the core retainer plate (5) that has seal ring (4) gets lodged on the inner-tube mouth (6), the outer surface of seal ring (4) closely contacts with the internal surface of inner-tube mouth (6), the upper surface of core retainer plate (5) is compressed by flange circle (1), flange circle (1) is installed in flange cup (2) by bolt (3), and flange cup (2) is fixed on the outside of inner-tube mouth.
2, storage-type electric water heater inner-tube mouth seal arrangement according to claim 1 is characterized in that the scope 0 of the tilt angle alpha of inner-tube mouth (6) is spent between 90 degree.
3, storage-type electric water heater inner-tube mouth seal arrangement according to claim 1 is characterized in that the following curved flange (7) that stretch out at the top place of core retainer plate (5) and forms groove (8) that the top of seal ring (4) embeds groove (8) the inside.
