Jacket insulation (explosion-proof fire) breathing valve

由于呼吸閥是固定在儲罐頂上的通風(fēng)裝置，以保證罐內(nèi)壓力的正常狀態(tài)，防止罐內(nèi)超壓或超真空，使儲罐遭受損壞，也可以起到減少罐內(nèi)液體揮發(fā)損耗的作用。

而儲存化工品時，一些化工介質(zhì)由于溫度的關(guān)系，需要將罐體和呼吸閥進行保暖。特別是呼吸閥，因與大氣直接相通，冷卻快，如保暖措施不當(dāng)，會在呼吸閥口腔處出現(xiàn)結(jié)晶或聚合，并會導(dǎo)致罐體被吸癟或破裂（國內(nèi)曾出現(xiàn)多次類似事故），特別是儲存對二甲苯丙醋酸、聚氯乙烯等介質(zhì)。

再如北方寒冷地區(qū)，由于低溫時間長，既然是儲存油品，但由于有水氣關(guān)系，也會使呼吸閥的閥盤和密封線之間、阻火器波紋帶夾縫中出現(xiàn)結(jié)冰。有的罐區(qū)雖然具備蒸氣絆熱，但效果不佳，迫使停止運作，影響正常生產(chǎn)，給國民經(jīng)濟帶來損失

為了解決上述問題，我廠特研制了夾套呼吸閥和夾套。產(chǎn)品在呼吸閥的本體外圍配上夾套隔層，設(shè)定蒸氣接口和冷凝水出口，調(diào)配適當(dāng)溫度，蒸氣融入夾套層中，為呼吸閥的閥腔和阻火器保暖。這樣，即可解決了有特殊溫度要求的化工品儲存的運作安全，又可解決寒冷地區(qū)冬天油品儲運可隨時操作的后顧之憂。其經(jīng)濟效益和社會效益是顯著的。

產(chǎn)品造型新穎科學(xué)，結(jié)構(gòu)合理緊湊，類型規(guī)格齊全。雙環(huán)隔層密封性能好，且易于檢查而又有安全可靠的特點。特別適用于化工、化纖罐區(qū)和寒冷地區(qū)的油品儲運罐上。

Due to the breathing valve is fixed to the top of the tank ventilation means, in order to ensure the normal state of the pressure inside the tank to prevent the tank overpressure or ultra-high vacuum, so that the tank has suffered damage, and also to reduce volatilization loss of liquid in the tank can play a role in.

And storage of chemicals, some chemical medium due to the temperature dependence, need to tanks and breathing valve warm. Special breathing valve, directly connected with the atmosphere, cooling fast, such as improper precautionary measures in the breathing valve Oral Department crystallization or polymerization, and will result in the tank being sucked deflated or broken (There have been several similar incidents) especially storage media xylene, propyl acetate, polyvinyl chloride.

Another example of the cold northern regions, due to the low temperature for a long time, since the oil is stored, but the moisture relationship also cause breathing valve disc and seal line between the corrugated flame arrester with cracks icing. Although some tank farm capable of hot vapor trip, but to little avail forced to stop working, affecting the normal production losses to the national economy

In order to solve the above problems, I developed a special jacket breathing valve and jacket Fire breathing valve to fill the gap. Products coupled with jacketed the breathing valve body peripheral compartment, set the vapor interface and the condensate outlet, the deployment of the appropriate temperature steam into the jacket layer, and a full range of warm breathing valve valve chamber and the flame arrester. In this way, you can solve the operational safety of the chemicals stored in special temperature

requirements, but also solve the cold winter oil storage and transportation can operate at any time to worry about. Its economic and social benefits are significant.

Novel scientific, reasonable and compact structure, type specifications. Bicyclic compartment sealing performance, and easy to check and have a safe and reliable. Especially suitable for oil storage and transportation tanks of chemicals, chemical fiber tank farm and cold regions.
