The exhaust valve is usually a solenoid valve.
The exhaust valve is usually a solenoid valve, in order to achieve a better sterilization effect, will be in the sterilization before exhausting the air for a while, that is, using steam instead of air in the chamber. The exhaust valve closes when the air is exhausted. Exhaust valve installed in the pump outlet or water distribution lines, used to exclude a large number of air collected in the pipe, or in the pipeline at the higher end of the collection of trace air emissions to the atmosphere, in order to improve the efficiency of the pipeline and the use of pumping machine, the pipe once there is a negative pressure, this valve quickly inhale the outside world air, in order to protect the pipeline due to the negative pressure of the production of the damage. After the sterilization is completed, you can use the exhaust valve to relieve pressure and open the lid faster.
Safety valve is a safety protection, when the system pressure exceeds the specified value, the safety valve opens, part of the system gas/fluid discharge into the atmosphere/outside the pipeline, so that the system pressure does not exceed the permissible value, so as to ensure that the system is not due to overpressure and accidents. Under normal circumstances the sterilizing dodo pot will stop heating when it detects that the temperature has reached the set value, intermittent heating to maintain the temperature and pressure, if this function is broken, then there may be heating all the time, resulting in super-high temperature in the pot, and finally explode, in order to avoid the explosion, so yo have a safety valve, and the pressure reaches the starting pressure of the safety valve after the leakage of the gas, so there will not be an explosion.

High-pressure steam sterilizer is the use of saturated pressure steam on the items for rapid and reliable sterilization equipment, applicable to medical and health care, scientific research, agriculture and other units. Classification of high-pressure steam sterilizer, according to the style size is divided into portable high-pressure sterilizer, vertical pressure steam sterilizer, horizontal high-pressure steam sterilizer and so on.
Safety valve is the opening and closing parts by the external force in a normally closed state, when the equipment or pipeline medium pressure rises above the prescribed value, by discharging the medium to the outside of the system to prevent the pipeline or equipment medium pressure exceeds the prescribed value of the special valve. Safety valve belongs to the automatic valve category, mainly used in boilers, pressure vessels and pipelines, control pressure does not exceed the prescribed value, for personal safety and equipment operation plays an important role in protection. Note that the safety valve must undergo a pressure test to use.
Exhaust valves are used in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating and solar heating systems and other pipeline exhaust. Because the water is usually dissolved in a certain amount of air, and the solubility of air with the temperature increases and decreases, so that the water in the cycle of the process of gas gradually separated from the water, and gradually gathered together to form large bubbles or even gas columns, because there is a complement of water, so there is often a gas production.
