Q: introduce the respiration valve principle of office answer: respiration valve is fixed in the Marine valve at the top of the tank ventilation, to ensure normal tank pressure condition, avoid tank overpressure or vacuum tank is destroyed, also can detract from tank liquid volatilization losses. Breathing valve plays a vapor barrier drainage effectiveness in steam heating system, selecting proper breathing valve, can make the steam heating facilities reach the supreme office rate. The respiration valve office principle is to use spring limit valve plate, or vote by the positive and negative pressure or breath. Breathing valve shall meet discharge function of two aspects of positive pressure and negative pressure, specific: when take positive pressure vessels, the vent valve opens breathe body discharge positive pressure; When bear negative pressure vessels, the respiration valve open suction gas discharge pressure. Choose the respiration valve, the first elected to the satisfaction of the special nature of the steam heating facilities the best run, before thinking about problems of other objective conditions, so choose what you demand of breather valve is accurate and effective. The safeguard stress within a certain range, to ensure the safety of the vessels. Breathing valve can not only maintain the pressure balance of the atmospheric storage tank, to ensure tank overpressure or vacuum damage, and can detract from tank medium and damage. One kind is reach a certain pressure, call or suck. The other is a default into completely not only breath. Can learn to use two suitable pressure one-way valve replacement. 。 Breathing valve of many kinds, each have different performance. 'Identify' steam and water solidification based on three principles: the degree of density difference, temperature difference and phase transition. If you want to achieve the ideal effect, will be for each product type breather valve office performance, unique places all aspects of understanding. Breathing valve need to be able to 'identify' steam and water solidification, ability to act as a vapor barrier drainage effect.
