Abstract

The utility model discloses a gas instantaneous water heater safety valve with drain function, including safe valve body and the sealing gasket being successively set in safe valve body, safe valve core, the pressure release spring of the valve element other end, it is characterized in that, draining spring is additionally provided with safe valve body outside the sealing gasket, the safety valve body end relief valve end of pressure release spring is additionally provided with water drain bolt, the safe valve core longitudinal section is H types, sealing gasket partly can enter in it with pressure release spring, valve element top can top pressure draining spring, the other end of draining spring can withstand on valve element body interior.The utility model has easy to use, dismounting simple, and with drain function.

Description

A kind of gas instantaneous water heater safety valve with drain function
Technical field
The utility model is related to gas instantaneous water heater technical field, more particularly, to the safety valve of gas instantaneous water heater Technical field.
Background technology
Existing safety valve mainly plays pressure release on existing market, and safety valve, and safety must be pulled down when serving as draining valve Valve is smaller, is easily lost;And existing draining valve only plays a role in the drainage, draining valve must be pulled down during draining, is easily lost.
Utility model content
The purpose of this utility model provides a kind of easy to use, dismounting aiming at the deficiencies in the prior art and simply adopted With a kind of safety valve with drain function.
In order to reach object above, the utility model patent is adopted the following technical scheme that:
A kind of safety valve with drain function, including safe valve body and the sealing that is successively set in safe valve body Pad, the pressure release spring of safe valve core, the valve element other end, it is characterised in that also set in the safe valve body outside the sealing gasket Draining spring is equipped with, the safety valve body end relief valve end of pressure release spring is additionally provided with water drain bolt.
As a further illustration of the above scheme, the safe valve core longitudinal section is H types, sealing gasket can with pressure release spring Be partially submerged into it, valve element top can top pressure draining spring, the other end of draining spring can withstand on valve element body interior.
Compared with prior art, a kind of safety valve that the utility model patent is provided has the advantages that:Safety The water drain bolt of safety valve end is tightened during valve bathing, whole valve body is used as safety valve, it is ensured that water safety;Need water-drainage antifreezing When, the water of internal heat exchanger can be discharged by unscrewing the water drain bolt of safety valve end, be not required to pull down valve body, be the advantage is that:
1st, without backing out water drain bolt completely during draining;
2nd, a safety valve has the function of relief valve and draining valve simultaneously.
Brief description of the drawings

Fig. 2 is pressure release status architecture schematic diagram of the present utility model.
Fig. 3 is hull-borne structural representation of the present utility model.
Description of reference numerals:1st, safe valve body 2, draining spring 3, sealing gasket 4, safe valve core 5, pressure release spring 6th, the power F that hydraulic pressure P is acted on sealing gasket in water drain bolt pipelinePPressure release spring force F1Draining spring force F2
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model patent.
As shown in figure 1, a kind of safety valve with drain function of the present utility model, including safe valve body 1 and set successively Put outside sealing gasket 3, safe valve core 4, the pressure release spring 5 of the other end of valve element 4 in safe valve body 1, the sealing gasket 3 Draining spring 2 is additionally provided with safe valve body 1, the end relief valve end of safe valve body 1 of pressure release spring 5 is additionally provided with row Timber bolt 6, the safe longitudinal section of valve core 1 is H types, and sealing gasket 3 can be partially submerged into it with pressure release spring 5, valve element top Ke Ding Pressure water spring 2, the other end of draining spring 2 can be withstood on inside valve element main body 1.
As shown in Figure 2 and Figure 3:Hydraulic pressure P in pipeline, the power F acted on sealing gasketP, pressure release spring force F1, draining spring force F2
Work as FP+F2<F1When, pressure release spring and draining spring are all in confined state, and sealing gasket is existed by pressure release spring compression On safe valve body, gas heater is in normal condition;
When hydraulic pressure is excessive, FP+F2>F1, in FPIn the presence of sealing gasket move down to form opening, pipe reclaimed water flows at opening Go out to reach pressure release purpose, it is ensured that water safety;
When winter, user needed water-drainage antifreezing, unscrew water drain bolt, pressure release spring is recovered former long F1=0, in F2Work Under, safety valve core ribbon sealing gasket and moved down, and the water in heat exchanger is discharged at opening reaches antifreeze purpose.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to In protection domain of the present utility model.
