Abstract
The invention discloses a safety valve with a drainage function for a rapid gas water heater. The safety valve comprises a safety valve main body as well as a sealing gasket, a safety valve element and a pressure relief spring at the other end of the valve element, which are sequentially arranged in the safety valve main body. The safety valve is characterized in that a drainage spring is further arranged in the safety valve main body outside the sealing gasket; a drainage bolt is further arranged at the tail end of a pressure relief valve on the end part of the safety valve main body with the pressure relief spring; the longitudinal section of the safety valve element is H-shaped, and the sealing gasket and the pressure relief spring can be partially embedded in the longitudinal section; the drainage spring can be jacked and pressed on the upper part of the valve element; and the other end of the drainage spring can be jacked in a valve element main body. The safety valve disclosed by the invention is convenient to use and simple to detach, and has a drainage function.
Description
Technical field
The present invention relates to gas instantaneous water heater technical field, more particularly, to the safe valve technology of gas instantaneous water heater
Field.
Background technology
Existing safety valve acts primarily as pressure release effect on existing market, and safety valve, and safety must be pulled down when serving as draining valve
Valve is less, is easily lost；And existing draining valve only plays a role in the drainage, draining valve must be pulled down during draining, be easily lost.
The content of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art and provides a kind of easy to use, dismounting and simply adopt one
Plant the safety valve with drain function.
In order to reach object above, patent of the present invention 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.
Further illustrating as such scheme, the safe valve core longitudinal section is H types, and 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 patent of the present invention is provided has the advantages that：Intrinsic safety full valve is washed
The water drain bolt of safety valve end is tightened during bath, whole valve body is used as safety valve, it is ensured that water safety；When needing water-drainage antifreezing,
Unscrewing the water drain bolt of safety valve end can discharge the water of internal heat exchanger, be not required to pull down valve body, have an advantage in that：
1st, without backing out water drain bolt completely during draining；
2nd, a safety valve is while there is the function of relief valve and draining valve.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to patent of the present invention.
As shown in figure 1, a kind of safety valve with drain function of the present invention, including safe valve body 1 and it is successively set on
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 safety outside the sealing gasket 3
Draining spring 2 is additionally provided with valve body 1, the end relief valve end of safe valve body 1 of pressure release spring 5 is additionally provided with draining spiral shell
Bolt 6, the longitudinal section of safe valve core 1 is H types, and sealing gasket 3 can be partially submerged into it with pressure release spring 5, and valve element top can top pressure row
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, acts on power F on sealing gasketP, pressure release spring force F1, draining spring force
F2
Work as FP+F2<F1When, all in confined state, sealing gasket is existed by pressure release spring compression for pressure release spring and draining spring
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, Guan Zhongshui flows from 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, make pressure release spring recover former long F1=0, in F2Work
With under, safety valve core ribbon sealing gasket and is moved down, and the water in heat exchanger is discharged from opening and reaches antifreeze purpose.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, some deformations and improvement can also be made, these belong to the present invention
Protection domain.
