The hydraulic control valve is a water pressure control valve, which consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose of use, function and location, it can be evolved into a remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve and so on. Traditional
convenience foods need to be soaked in boiling water for consumption.
Some special people, such as wilderness adventures, tourism, troops, and
police officers, cannot be eaten without boiling water. Self-heating
Rice does not need boiling water when cooking, no need for thermal
power, tear open the outer packaging, pour the pure water bag inside it
into the heating bag, the water and the heating bag will automatically
mix and heat up, steam the rice and the dishes, 8-15 minutes Edible. Convenience Rice,Fast Food Rice,Self-Heating Rice,Chicken Self-Heating Rice Ningxia Saiwaixiang Food Co., Ltd. , https://www.nxswxfood.com
The hydraulic control valve is divided into two types: diaphragm type and piston type. The working principle is the same. Both the above-mentioned downstream pressure difference ΔP is the power, which is controlled by the pilot valve, so that the diaphragm (piston) hydraulic differential operation is completely adjusted by the hydraulic force. Make the main valve disc fully open or fully closed or in a regulated state. When the pressure water entering the control chamber above the diaphragm (piston) is discharged to the atmosphere or the downstream low pressure zone, the pressure acting on the bottom of the valve disc and below the diaphragm is greater than the pressure value above, so push the main valve disc to fully open When the pressure water in the control chamber above the diaphragm (piston) cannot be discharged to the atmosphere or the downstream low pressure zone, the pressure acting above the diaphragm (piston) is greater than the pressure below, so the main valve disc will be used. Pressing to the fully closed position; when the pressure in the control chamber above the diaphragm (piston) is between the inlet pressure and the outlet pressure, the main valve disc is in an adjusted state, the adjustment position of which depends on the needle valve in the conduit system and Joint control of the regulating valve. The adjustable pilot valve can open or close its own small valve port by the downstream outlet pressure and change with it, thereby changing the pressure value of the control chamber above the diaphragm (piston) and controlling the adjustment position of the square valve disc.
Decommissioning
the ingredients of the Self-Heating Rice heating package: Inventing a
multi-purpose self-heating bag, mainly using roasting diatomaceous
earth, iron powder, aluminum powder, coke powder, activated carbon, salt
to form a bag, which can be heated to 60 °C It
can be used for heating in winter, medical hot compress, adding
quicklime, sodium carbonate and water. The temperature can be raised to
120 °C to heat meals or steamed food. The temperature is kept for 20
minutes to 100 ° C for 60 minutes and 60 ° C after 60 minutes. The
material used in the winter heating and hot compressing can be
repeatedly used, and after being used, it can be mixed with quicklime
and sodium carbonate, and then heated to heat the food.
