Abstract

A safety valve is disclosed. The valve body is arranged with a piston floater, the central hole of the piston floater is a water outlet, the top portion of the valve body is arranged with a screwed joint removable roof cover, the water outlet pipe connector of the valve body is arranged with an automatic pressure-reducing valve cock, the water inlet pipe connector is connected with an inlet pipe, the water outlet pipe connector is connected with a hot-water kitchen range or is put in a water storage crock. When the water level ascends, the piston floater automatically ascends to close the water inlet with the floatage function. When the water level descends, the piston floater descends to automatically open the water inlet in order to feed water with the sole weight function, and keeps some space, at the same time the pressure-reducing valve cock can automatically escape air and reduce pressure, thereby achieving the goal of automatic open and close, safety, and safety.

Description

Safety valve

Technical field

The utility model relates to supply of daily life waterpipe valve, especially is applicable to the automatic safety safety valve of domestic hot water's kitchen range and water storage cylinder.

The supply waterpipe valve that present people generally use, by valve body, valve rod, piston, piston packing ring, sealing nut, compositions such as swing handle, in the using process, because artificial frequent switch, threaded stem is easy to wear and tear stripped thread and causes leaking, and particularly utilizes the hot water kitchen range family of coal stove waste heat hot water, always worry that hot water boiling pressure is excessive in the hot water kitchen range, cause hot water kitchen range explosion safety accident.The situation that the while tap water is cut off the water temporarily happens occasionally, and particularly the retaining of water storage cylinder is generally all adopted in the water-deficient area of Timing water supply, owing to there is not the necessary manual control switch's retaining of automatic safety safety installations, therefore, the daily life water is inconvenience very.

Summary of the invention

The purpose of this utility model provides a kind of supply water pipe automatic safety safety valve that has improved, its recloser water inlet easily, and keep the container certain space, but automatic deflation decompression simultaneously, thus avoided leaking and security incident such as blast.

The solution that the utility model adopts is: be provided with piston floating body in the valve body, the center hole of piston floating body is a water outlet, the top of valve body is the removable top cover that is threaded, the valve body titting water outlet is provided with automatic decompression valve mouth, fill hose joint taps into water pipe, titting water outlet connects the hot water kitchen range or puts into the water storage cylinder, tap water enters valve body by water intake, enter hot water kitchen range or water storage cylinder through piston floating body center hole water outlet, when water level rises, piston floating body is risen by floating function automatically, slowly close water intake, and keep hot water kitchen range and the certain space of water storage cylinder, even the interior water of hot water kitchen range becomes boiling water like this, certain hot gas space is also arranged, the decompression valve mouth decompression of can slowly exitting simultaneously automatically, when drawdown, piston prisoner body is subjected to self gravitation effect decline to open water intake automatically to intake, thereby reach recloser, the purpose of security insurance.

The removable top cover at above-mentioned safety valve top can take out pressurized machine of connection, when the needs supercharging, be that available hand is pressed pressurized machine sleeve gland and snapped in location card, because the elastic force effect of pressurized spring makes booster rod press piston floating body downwards and opens the water intake water inlet automatically, increases the pressure of water to increase pressure.

Because the utility model adopts piston floating body and recloser, therefore have advantages such as simple in structure, easy to manufacture, recloser, easy to use, with low cost, security insurance.

Description of drawings

Do the detail explanation below in conjunction with drawings and Examples;

Fig. 1 is the structural drawing of facing of safety valve;

Fig. 2 is the structural drawing of facing of pressurized machine;

Embodiment

In the safety valve shown in Figure 1, piston floating body 5 by heat resisting and pressure resisting plastics or metal processing is arranged in the valve body 1, the center hole of piston floating body 5 is a water outlet 6, the top of valve body 1 is the removable top cover 7 that is threaded, the bottom titting water outlet 4 of valve body 1 is provided with the automatic decompression valve mouth 8 of similar bicycle valve cock formula, between removable top cover 7, titting water outlet 4 and the piston floating body 5 seal washer 9 is housed respectively.

In pressurized machine shown in Figure 2, the top of pressurized machine 10 can slide up and down and be sleeve gland 11, and the bottom is a pressurized machine joint 12, pressurized machine joint 12 is provided with location card 13, be provided with pressurized spring 14 in the cavity of pressurized machine, booster rod 15, the end face of pressurized machine joint 12 is equipped with seal ring 16.

Fill hose joint 2 connects the tap water intake pipe during use, titting water outlet 4 connects hot water kitchen range or water storage cylinder, tap water enters valve body 1 by water intake 3, center hole water outlet 6 through piston floating body 5 enters hot water kitchen range or water storage cylinder, when water level rising contact piston buoyancy aid 5, because buoyancy has surpassed the gravity of piston prisoner body 5 and the friction of buoyancy aid and valve body, piston floating body 5 is subjected to the automatic rising of floating function slowly to close water intake 3, and certain space in the maintenance hot water kitchen range, automatically decompression valve mouth 8 can constantly discharge the hot gas decompression simultaneously, when drawdown, piston floating body 5 is descended by the self gravitation effect and opens water intake 3 water inlets automatically, thereby realizes recloser, the purpose of security insurance.

When needs pressure increases, desirablely go out removable top cover 7, connection pressurized machine 10, by lower sleeve gland 11 and snap in location card 13, because the elastic force effect of pressurized spring 14, booster rod 15 presses piston floating body 5 downwards and opens water intake 3 water inlets automatically with hand, increase the heat hydraulic pressure with the pressure that increases in the hot water kitchen range, and can keep the certain pressure of hot water kitchen range to weigh, surpass and weigh the spring pressurized and close water intake 3 automatically, less than measurement, open water intake 3 water inlet superchargings automatically.
