Protective energy-saving high-pressure boiler

Abstract

The invention provides a protective energy-saving high-pressure boiler comprising a boiler body and a boiler lid matched with the boiler body, wherein the boiler lid is also provided with a housing; the housing is composed of a shell and an inner sleeve sleeved with the shell and is internally provided with a sealed cavity; the housing is provided with a valve position hole for avoiding a pressure-limiting valve; and a steam discharging clearance is arranged between the valve position hole and the peripheral side of a valve bonnet. The inner side of the housing is provided with a diversion trench for discharging oil and water. Thermal insulation materials can be filled in the cavity of the housing. The boiler body is provided with a thermal insulation cylinder made of foamed plastic material, and the lower part of the boiler body is provided with a thermal insulation sleeve gasket sleeved on the bottom of the high-pressure boiler and made of the foamed plastic material. The high-pressure boiler provided by the invention overcomes defects easily existed in the traditional thermal insulation technology, has more ideal protection, energy-saving and thermal insulation effects and is beneficial to energy conservation and emission reduction so as to have popularization and application values.

Description

Technical field [0001] The invention involves a protective high -pressure cooker. Background technique [0002] Most of the boiled high -pressure cookers used on gas stoves or electromagnetic cookers daily (hereinafter referred to as high -pressure cookers or ordinary high -pressure cookers) are mostly made of aluminum alloy or stainless steel materials, which brings many convenience to people's lives.During the cooking process, fire control can be performed at any time, which has its certain advantages.However, the surface of the metal surface of ordinary high -pressure cookers is large, especially the pot lid of high -pressure cookers. In addition to a small part of the handle of the lid, most of the metal appearance is exposed. During the cooking process, the surface of the exposed pot lid is on the relatively high temperature.Due to the high surface temperature, when the human body accidentally touches it, it is easily scalded or burned; more obvious is that during the cookin...

Problems solved by technology

However, the metal surface of ordinary pressure cooker has a large exposed area, especially the pot lid of the pressure cooker. Except for a small part covered by the handle of the pot cover, most of the metal surface is exposed. During the cooking process, the exposed pot cover surface is at a relatively high temperature. state, and because of its high surface temperature, when the human body accidentally touches it, it is easy to be scalded or scalded; the more obvious disadvantage is that in the process of cooking in a pressure cooker, no matter whether a gas stove or an induction cooker is used, the temperature of the high-temperature pressure cooker The lid of the pot is always in a state of radiating heat outward, and because of its high surface temperature, large exposed area, and a lot of heat loss, especially in winter when the ambient temperature is low, the temperature difference between the lid and the surrounding environment is large, and the heat dissipation is faster and the loss The heat is more, which is not conducive to energy saving when cooking, and is also not conducive to the heat preservation of the pressure cooker after stopping cooking and heating.
