Automatic Venting Valve Introduction During the operation of the heating, ventilation and HVAC systems, the harmful effects caused by the water (such as hydrogen and oxygen) released from the water during heating can damage the system and reduce the thermal effects. If these gases can not be discharged in time Lost will have a lot of adverse consequences. Such as: corrosion caused by oxidation; the formation of airbags in the radiator; unbalanced hot water circulation is not smooth, so that some radiators do not partially heat; noise when the pipe runs with gas; vortex phenomenon circulating pump. This shows that the use of automatic exhaust valve an important role. The new automatic vent valve design takes into account all the known disadvantages, such as impurities in the water, oil, suspended solids, turbulence in the valve liquid during venting, vibrations in the piping and equipment to which the vent valve is connected, and more. ) Excellent performance: Reliable operation no matter whether the system has just been filled with water (a large amount of gas is discharged when the system is operating), or when the system pressure is too high, it requires proper drainage and pressure relief. First, the characteristics: 1. Reliable performance. Exhaust valve exhaust mechanism is very reliable, at the factory before each valve through the exhaust test and pressure seal experiment. Individual components are cast from high precision, resulting in a perfect fit. 2. Easy to maintain. Automatic venting is fitted with a shut-off valve that allows easy removal of the vent valve from the system for maintenance while the water in the system will not flow out, so there is no need to empty the system. 3. Only exhaust, no drainage. Steam, water disc design using a special structure to ensure that when the exhaust is not drained. 4. As long as the system is under pressure, the exhaust valve will continuously exhaust. Second, the main purpose: Automatic exhaust valve for: independent heating system; central heating system; radiant floor heating system; solar heating system; heat pump system; central air conditioning; heating boilers. Third, the automatic exhaust valve works When there is air in the system, the gas gathered in the upper part of the exhaust valve, the body bubble accumulation so that the float drops with the water level, so open the exhaust piston; gas exhausted, the water level rise, floating The ball also rises, closing the exhaust piston. If tightening the bonnet on the side of the body, the vent valve stops venting, and normally the bonnet should be open.
.Perilla Seed
1. Lower lipids and blood pressure
The rich linolenic acid in Perilla Seed Oil can reduce serum cholesterol, triglycerides, low-density lipoprotein and very low-density lipoprotein, thereby inhibiting thrombosis and preventing myocardial infarction and cerebral infarction. In addition, α-linolenic acid Acid can also reduce blood viscosity, increase blood oxygen-carrying capacity, inhibit the synthesis of triglycerides, and increase the metabolism of various lipids in the body. Therefore, perilla seed oil has a particularly obvious effect in lowering lipids and blood pressure, especially for hyperlipidemia. and borderline hypertension, the effect is more prominent.
2. Protect liver
The α-linolenic acid in perilla seed oil can effectively inhibit fat synthesis, break down fat and excrete it from the body. Daily consumption can prevent the formation of fatty liver.
3. Strengthen the brain and protect eyesight
CCTV's "Encyclopedia Quest" reported that α-linolenic acid is one of the basic raw materials for nerve cell synthesis and a key nutrient that determines the development of human intelligence. It is called "brain gold". Correct supplementation of linolenic acid can improve the IQ and intelligence of infants and young children. Increase by 20%-30%, pregnant women and children must supplement.
