Abstract
The utility model discloses a steam release valve of an electric steam boiler. A piston and a top rod (i.e. a piston top rod) connected with the piston are arranged in a cuboidal valve body. The steam release valve comprises a return spring, a sealing plug, a piston sealing ring and a front end cover. The piston top rod extends out of the valve body through the through hole arranged in the middle of the front end cover at one end of a valve body and is ejected at a proper position o n a boiler door. A steam inlet communicated with high-temperature steam in a boiler inner liner is arranged at the other end of the valve body. A steam release hole is arranged on the side surface of the valve body. The sealing plug is arranged at the inner end of a piston and the piston is sealed with the steam inlet of the valve body. The sealing ring is arranged between the circumference of the piston and the inner wall of the valve body. The return spring is arranged between the inner end of the piston and the inner wall of the steam inlet. An installation fixing plate for installation is arranged on the outer wall of the valve body. The utility model has the advantages that, after the operation of the electric steam boiler is completed, high-temperature steam of certain pressure in the boiler can be released slowly through the steam release hole of the steam release valve and scalding accidents caused by steam suddenly rushing out of the boiler inner liner when the boiler door is opened are avoided.
Description
Technical field
The utility model relates to a kind of safety device of HTHP electric steam furnace, specifically shows the steam escape valve that electric steam furnace is released steam.
Background technology
Not long ago the applicant had invented a kind of energy-efficient domestic electric steaming furnace, replaced popular micro-wave oven at present with it, made culinary electric cooking appliance environmental protection more, more energy-conservation.This domestic electric steaming furnace is the horizontal flue that a columnar similar present pressure cooker is set in the middle of square casing, is provided with circular fire door lid in the casing front, and the fire door lid is connected with hinge with casing, and the fire door lid can be a core rotation with its center.Side at the fire door lid is provided with handle, and the flange bead of fire door lid and flue all is provided with the clutch buckle of dislocation, seals with O-ring seal between the two.In flue, be provided with and shelve the steaming lattice that cooking is used, be provided with the feedwater pore, below steaming lattice, be provided with dish-shaped electric heating plate at the flue rear wall.For safety, therefore be provided with steam vent and safety valve at the flue top, the design is exactly to the electric steam furnace safety device that steam uses of releasing.
The utility model content
The purpose of this utility model is: be equipped with a kind of safety device--steam escape valve of scalding avoided for the electric steam furnace that is full of high-temperature steam in the flue when door opened, allow the user of electric steam furnace feel more relieved.
The technical scheme of the utility model technical solution problem is: the steam escape valve of electric steam furnace, be in the valve body of cuboid, piston to be set and coupled push rod is a piston mandril, also comprise back-moving spring, sealing-plug, piston packing ring, drive end bearing bracket, described piston mandril by be located at valve body one end fixedly the through hole in the middle of the drive end bearing bracket of usefulness extend out to outside the valve body, be provided with the air intake that is connected with high-temperature steam in the flue at the other end of valve body, be provided with vent port in valve body side near air intake, the inner end of described piston is provided with sealing-plug, seal mutually with the air intake of valve body, be provided with sealing ring between described outside piston and the valve interior wall, be provided with back-moving spring between the valve interior wall of the inner end of piston and air intake one end.
On the valve outer wall of described cuboid, be provided with the mounting plate that usefulness is installed.
The utility model has the advantages that, when electric steam furnace finishes in work, remained certain high temperature steam in the stove and can slowly let out vapour that in the time of can be because of oven door opening, high-temperature steam be gone out in the flue suddenly and caused the scald accident by steam escape valve.
Description of drawings
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is a profile schematic diagram of the present utility model;
Each title and mark among the figure: 1. piston mandril, 2. drive end bearing bracket, 3. valve body, 4. piston packing ring, 5. back-moving spring, 6. vent port, 7. sealing-plug, 8. mounting plate, 9. air intake.
The specific embodiment
As depicted in figs. 1 and 2, the mounting plate 8 of steam escape valve is fixed on the appropriate location of electric steam furnace, air intake 9 is connected with the flue of electric steam furnace, vent port 6 is outside flue. and piston in the cuboid valve body 3 and coupled push rod are that piston mandril 1 extend out to outside the through hole in the middle of the drive end bearing bracket 2 of valve body 3, and withstand on the stove door plant of electric steam furnace. when fire door is closed, back-moving spring 5 is compressed, piston mandril 1 advances inwards, the sealing-plug 7 of piston inner end clogs the air intake 9 of valve body 3, high-temperature steam in the flue can not be entered in the valve body 3, this moment, the flue of electric steam furnace was in air-tight state. when electric steam furnace work finishes, when fire door is opened a little, because the tension force effect of back-moving spring 5, piston mandril 1 spring 5 that is reset is extrapolated, and sealing-plug 7 leaves air intake 9, and high-temperature steam enters in the valve body 3, and from be located at the vent port 6 near valve body 3 sides of air intake 9, slowly release, therefore can not go out suddenly quickly and cause the scald accident.
