Abstract
The utility model relates to a pollution discharge port end plug for an electric water heater, comprising a screw. The pollution discharge port end plug is connected with the bottom end of a pollution discharge water tube on the electric water heater by the screw. The main technical features of the utility model are that: a pressure relief thin slice for relieving pressure when the pressure exceeds the safe pressure is arranged on the pollution discharge port end plug. A through hole is arranged at the pollution discharge port end plug and the pressure relief thin slice is pressured at the bottom of the through hole by an external screw on a hollow pressure screw and an internal screw on the through hole. The pollution discharge port end plug effectively relives the pressure when a safe valve is invalidated and prevents the inner bag bursting by the inner high pressure.
Description
Technical field: the utility model relates to a kind of sewage draining exit plug that is used for electric heater.
Background technology: in the prior art; electric heater is equipped with safety valve usually; when the hydraulic pressure in the inner bag surpassed protection pressure, safety valve was opened, and the water of discharging in the inner bag carries out pressure release; in case safety valve lost efficacy; pressure increases sharply in hot water heating process in the inner bag, and when surpassing the pressure that inner container of electric water heater can bear, internal pressure will be burst inner bag; causing when existing safety valve to lose efficacy can not pressure release, and inner bag is by defectives such as its inner high pressure burst.For overcoming these defectives, the sewage draining exit plug that is used for electric heater is improved.
Summary of the invention: technical problem to be solved in the utility model is that a kind of sewage draining exit plug that is used for electric heater will be provided, and its pressure release when safety valve lost efficacy effectively avoids inner bag to be burst by its inner high pressure.
The technical scheme that its technical problem that solves the utility model adopts is that described sewage draining exit plug is provided with screw thread, the sewage draining exit plug is connected by the bottom of the sewage pipe on screw thread and the electric heater, described sewage draining exit plug is provided with the pressure release thin slice of pressure release when surpassing safe pressure, described sewage draining exit plug is provided with through hole, described sewage draining exit plug is provided with through hole, and the pressure release thin slice screws the bottom that is pressed on through hole by external screw thread on the housing screw of hollow and the internal thread on the through hole.
Described through hole is step-like through hole.
Described pressure release thin slice is by the bottom sealing of rubber seal and through hole.
Described pressure release thin slice is by the bottom sealing of fluid sealant and through hole.
The inboard of described sewage draining exit plug bottom is provided with magnesium rod seat.
The outside of described sewage draining exit plug bottom is provided with installation base.
Described pressure release thin slice is that metal material is made, and the thickness of pressure release thin slice is 0.3～1.5mm.
The thickness of described pressure release thin slice is 0.4mm.
The thickness of described pressure release thin slice is 0.9mm.
The thickness of described pressure release thin slice is 1.4mm.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts the sewage draining exit plug to be provided with the pressure release thin slice of pressure release when surpassing safe pressure, the sewage draining exit plug is provided with through hole, described sewage draining exit plug is provided with through hole, the pressure release thin slice screws the structure that is pressed on via bottoms by external screw thread on the housing screw of hollow and the internal thread on the through hole, when the internal pressure of inner bag surpasses the safe pressure value, thereby the hot water in the inner bag flows out from pressure relief device and reaches the pressure release effect, so its pressure release when safety valve lost efficacy effectively avoids inner bag to be burst by its inner high pressure.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view that dwindles of sewage draining exit plug 1 among Fig. 1.
Fig. 3 is the structural representation that sewage draining exit plug 1 is connected with sewage pipe 5 among Fig. 1.
Fig. 4 is applied in structural representation on the electric heater for sewage draining exit plug 1 among Fig. 1.
The specific embodiment: referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, shown in the accompanying drawing 4, present embodiment comprises sewage draining exit plug 1, inner bag 4, sewage pipe 5, pressure release thin slice 6, sewage pipe 5 one ends are communicated with inner bag 4 by welding manner, the other end is connected with sewage draining exit plug 1 by the screw thread 2 on the sewage draining exit plug 1, sewage draining exit plug 1 is provided with step-like through hole 10, pressure release thin slice 6 is arranged on the step of through hole 10, through hole 10 is provided with internal thread, pressure release thin slice 6 screws the bottom that is pressed on through hole 10 by the housing screw 8 of hollow with internal thread, and bottom sealing by rubber seal 7 or fluid sealant and through hole 10, the inboard of sewage draining exit plug 1 bottom is provided with magnesium rod seat 9, and the outside of sewage draining exit plug 1 bottom is provided with installation base 3.
Pressure release thin slice 6 can be circle or other shape, can adopt sheet metals such as copper or aluminium to make.The thickness of pressure release thin slice 6 is 0.3～1.5mm, as can be 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm etc.Pressure release thin slice 6 is the aluminum slice of thickness 0.9mm in this enforcement.
Electric heater is when energising work, when the safety valve of electric heater lost efficacy, pressure increases sharply in hot water heating process in the inner bag 4, when the internal pressure of inner bag 4 surpasses the safe pressure value, its inner high pressure crushes pressure release thin slice 6, and the hot water in the inner bag 4 flows out from pressure release thin slice 6 breakages, thereby the pressure in the inner bag 4 is descended, avoid inner bag 4 to damage even blast, ensure the safety of user and electric heater.
