Abstract
The utility model discloses a reverse reflux device of a safety valve of an electric water heater, which is composed of a body, a valve cap, a pressure spring, a gasket base, a flat gasket, a casing and a positioning column, wherein the flat gasket is embedded in the gasket base, the pressure spring is matched with the gasket base and is integrated in matching type through being pushed by the valve cap to be arranged in the body, a groove on the inner wall of the casing is clamped on a lug boss of an outer ring of the body, and the positioning column is clamped on the body and is positioned through a pressure regulating cap. The utility model has the characteristics that no whistler is generated when discharging the pressure under any water pressure, the hot water can not reflux when water is cut off, the casing can not be dashed out by water when high-voltage reflux of the water heater, etc. The utility model is the novel reverse reflux device of the safety valve of the electric water heater.
Description
One, technical field
The utility model relates to a kind of reverse reflux device, and is especially relevant with electric water heater safety valve reverse reflux device.
Two, background technology
The reverse reflux device is the critical piece in the safety valve, and it mainly acts on is that the electric heater inner bag is shielded, and the reverse sealing function when running water is cut off the water supply.The safety valve of producing on the existing market is usually because the problem of this device, and when running water to certain pressure and oppositely during pressure release, uttering long and high-pitched sounds appears in safety valve easily, when running water is cut off the water supply, hot water flows backwards, and during the reverse pressure release of inner bag high pressure, and gasket seal is by the high pressure valve body phenomenon that recoils out.
Three, summary of the invention
The purpose of this utility model provides a kind of no howling, and hot water can not flow backwards and the inner bag high pressure electric water heater safety valve reverse reflux device that gasket seal can not be rushed out when sluicing when running water was cut off the water supply.
For achieving the above object, the utility model is realized by following technical solution: electric water heater safety valve reverse reflux device is made up of body, valve gap, stage clip, washer seat, flat shim, overcoat and reference column, flat shim is embedded in the washer seat, stage clip cooperates with washer seat, head on to be contained in by valve gap and fit in one in the body, groove on the outer casing inner wall is stuck on the boss of body outer ring, and reference column is stuck on the body, and locatees by the pressure regulation cap.
Described electric water heater safety valve reverse reflux device, overcoat and body fit in one separately.
The utility model compared with prior art has the following advantages: (one) is compact conformation, reasonable, and manufacturing cost can reduce greatly, and stability and economy have both; (2) be that the reverse reflux device passes through to regulate the safety valve of discharge applicable to any style, and be not subjected to influence of hydraulic pressure, pressure release can not produce howling under any hydraulic pressure; (3) be this reverse reflux device oppositely sealing place overcoat and body fit in one separately, increased the overcoat planar smoothness greatly, make that hot water can not flow backwards when cutting off the water supply; (4) reverse reflux device outer casing inner wall has a groove, blocks cooperation by body outer ring boss, and overcoat can not gone out by water when making the water heater high pressure reflow; (5) be that the assembling of this device is simple, convenient, can be widely used on the electric water heater safety valve of any kind.
Four, description of drawings
Fig. 1 is the utility model electric water heater safety valve overall structure figure.
Fig. 2 is the utility model electric water heater safety valve reverse reflux apparatus structure schematic diagram.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, electric water heater safety valve is made up of main casing 1, the body 2 that leaks, water inlet spring 3, pressure regulation cap 4 and reverse reflux device 14, as shown in Figure 2, reverse reflux device 14 is made up of body 5, valve gap 6, stage clip 7, washer seat 8, flat shim 9, overcoat 10 and reference column 11, flat shim 9 is embedded in the washer seat 8, stage clip 7 cooperates with washer seat 8, head on to be contained in the body 5 by valve gap 6 and fit in one, groove 13 on overcoat 10 inwalls is stuck on the body 5 outer ring boss 12, reference column 11 is stuck on the body 5, and by pressure regulation cap 4 location.Overcoat 10 can fit in one separately with body 5.
Claims (2)
1, a kind of electric water heater safety valve reverse reflux device, comprise body (5), it is characterized in that: it also comprises valve gap (6), stage clip (7), washer seat (8), flat shim (9), overcoat (10) and reference column (11), flat shim (9) is embedded in the washer seat (8), stage clip (7) cooperates with washer seat (8), is headed on to be contained in the body (5) by valve gap (6) to fit in one, and the groove (13) on overcoat (10) inwall is stuck on body (5) the outer ring boss (12), reference column (11) is stuck on the body (5), and locatees by pressure regulation cap (4).
