Abstract
Disclosed is an electric pressure cooker used safety valve belonging to the home electric cooker technique field, which comprises a valve body and a valve core, the utility model is characterized in that the cavity of the valve body (4) is provided with a spilt type anticorrosion sleeve, a small hole is arranged at the upper part of a valve rod (7), and a sealed sleeve (3) is arranged inside the valve rod, the utility model has advantages of anticorrosion, antirust, good sealing effect and safety protection function.
Description
A kind of electric pressure cooking saucepan safety valve belongs to family expenses electric cooking appliance field, particularly electric pressure cooking saucepan special-purpose member.
The electric pressure cooking saucepan safety valve, it is a kind of electric pressure cooking saucepan safety guard, when the pressure cooker internal pressure reaches a certain design load, the safeguard protection effect to electric pressure cooking saucepan is played in the safety valve step-down of losing heart, and mainly there are 2 deficiencies in the safety valve of prior art: (1) valve body adopts electroplating technology, because body cavity plating difficulty is big, body cavity is owing to being got rusty by the steam corrosion in the safety valve use, and rusty stain leaks not attractive in appearance, and is unhygienic; (2) valve is stifled directly contacts with valve rod or sealing shroud is enclosed within valve and blocks up, the former is owing to be hard contact, be easy to generate gas leak phenomenon in the use, though latter's sealing effectiveness is significantly improved, but block up the shear force that is subjected to from valve rod because the sealing shroud that rubber is made is fixed on valve, the section of being easy to generate is split phenomenon.
The purpose of this utility model just is that research and design is a kind of and has anticorrosion, antirust, a good sealing effect, can play the electric pressure cooking saucepan safety protective valve of safeguard protection effect again.
The purpose of this utility model realizes in the following way:
This electric pressure cooking saucepan safety valve comprises valve body, spool, it is characterized in that: split type anticorrosion cover is set in the cavity, and valve rod 7 tops are provided with aperture, in be provided with sealing shroud 3.
The purpose of this utility model also can realize in the following way:
Described electric pressure cooking saucepan safety valve, it is characterized in that: described anticorrosion cover 5 is for split type, constitute by anticorrosion cover body 5 and anticorrosion upper shield 6, inboard, anticorrosion cover body 5 bottom is provided with a circle Baltimore groove, anticorrosion cover body 5 is embedded in the cavity of valve body 4, anticorrosion upper shield 6 outer peripheries have a circle projection, cooperate to be contained in anticorrosion cover 5 body bottoms.
Described electric pressure cooking saucepan safety valve is characterized in that: described anticorrosion upper shield 6 is the disk shape, is provided with passage 8.
Described electric pressure cooking saucepan safety valve, it is characterized in that: spool comprises stifled 2, the sealing shroud 3 of seal spool, sealing shroud 3 is contained in the hole on valve rod 7 tops, stifled 2 tops of seal spool are screw shaped, pass that hole and valve button 1 are connected and fixed on the anticorrosion cover body 5 of valve body, the bottom is a pyramidal structure, with flexible flexible connection of sealing shroud 3 formation in valve rod 7 upper holes.
Electric pressure cooking saucepan safety valve of the present utility model, main inventive point is to have designed the split type anticorrosion cover that is installed in valve body 4 inner chambers, comprise anticorrosion cover body 5 and anticorrosion cover upper shield 6, inboard, anticorrosion cover body 5 bottom is provided with a circle Baltimore groove, anticorrosion cover body 5 valve body 4 inner chambers of packing into, anticorrosion upper shield 6 outer peripheries have a circle projection, cooperate to be contained in anticorrosion cover body 5 bottoms, in addition valve rod 7 tops are provided with aperture, in be provided with sealing shroud 3.Compared with prior art has following advantage: steam and valve body 4 are isolated, prevented the corrosion of steam effectively to valve body 4 inner chambers, stifled 2 bottoms of seal spool are pyramidal structure, form flexible the flexible connection with the sealing shroud 3 that is provided with in the valve rod 7 top apertures, overcome the shear force of valve rod sealing shroud.Improve sealed precision, prolonged the service life of sealing shroud.Have anticorrosion, antirust, good sealing effect, can play the special-purpose safety protective valve of electric pressure cooking saucepan of safeguard protection effect again.
Fig. 1 is that the utility model electric pressure cooking saucepan cuts open with safety valve structure and shows schematic diagram;
Fig. 1 is the most preferred embodiment of electric pressure cooking saucepan of the present utility model with safety valve, below in conjunction with accompanying drawing electric pressure cooking saucepan of the present utility model is described further with safety valve:
Among Fig. 1: 1 valve button, 2 seal spools block up 3 sealing shrouds, 4 valve bodies, 5 anticorrosion cover body 6 anticorrosion cover upper shield 7 valve rods.At first that valve button 1, seal spool is stifled 2, sealing shroud 3, valve body 4, anticorrosion cover body 5 anticorrosion cover upper shield 6 valve rods 7 are made, and fit together as shown in Figure 1, and electric pressure cooking saucepan of the present utility model is made with safety valve.The course of work is as follows: set uniform temperature; pressure is connected the power supply heat temperature raising; because the sealing shroud 3 in Yan Xin sealing stifled 2 and valve rod 7 upper holes is for flexibly connecting; can play the better seal effect; save time; energy-conservation; because of the course of work and the usual pressure pot of electric pressure cooking saucepan is diverse; therefore; use under the normal condition is not need pressure limiting valve venting decompression; the main purpose that pressure limiting valve is set is the duplicate protection that prevents to occur in the pot improper situation; as artificial venting; or the electric pressure cooking saucepan control system is malfunctioning; when the electric pressure cooking saucepan internal pressure surpasses certain setting value; gas produces seal spool stifled 2 and upwards pressure in the valve rod 7 top apertures; when this pressure surpasses self gravitation; move on the valve body 4, form the gap between seal spool stifled 2 and valve rod 7 sealing shrouds 3, gas is by valve rod 7 central upper portion holes in the electric pressure cooking saucepan; valve body 4 inner chambers; aperture 8 on the anticorrosion cover upper shield 6 is discharged; reduce gas pressure in the electric pressure cooking saucepan, play the safeguard protection effect.Again owing to be provided with the anticorrosion cover that is installed in valve body 4 cavitys, steam and valve body 4 are isolated, prevented the corrosion of steam effectively to valve body 4 inner chambers, stifled 2 bottoms of seal spool are pyramidal structure, form flexible the flexible connection with the silicon rubber software sealing shroud 3 in valve rod 7 upper holes, overcome the shear force of 7 pairs of sealing shrouds 3 of valve rod, improved sealed precision, prolonged the service life of sealing shroud 3.Have anticorrosion, antirust, good sealing effect, can play the special-purpose safety protective valve of electric pressure cooking saucepan of safeguard protection effect again.
