वायवीय गेंद वाल्व के जीवन का विस्तार कैसे करें

वायवीय गेंद वाल्व वाल्व में वाल्व बॉडी, बॉल, वाल्व स्टेम और वायवीय एक्ट्यूएटर शामिल हैं। वाल्व बॉडी और वायवीय एक्ट्यूएटर के बीच वाल्व स्टेम पर एक ब्रैकेट की व्यवस्था की जाती है। ब्रैकेट और वाल्व स्टेम के बीच वाल्व स्टेम क्रमिक रूप से एक पैकिंग ग्रंथि, एक पैकिंग और नीचे से नीचे तक एक पैकिंग पैड प्रदान किया जाता है। वाल्व स्टेम और वाल्व बॉडी के बीच एक स्लाइडिंग बुश की व्यवस्था की जाती है, वाल्व बॉडी का एक छोर सिरेमिक वाल्व कवर से जुड़ा होता है, और गोला पूर्ण सिरेमिक सिंटरिंग से बना एक गोला होता है। वाल्व शरीर के दूसरे छोर को वाल्व बॉडी के साथ एकीकृत रूप से गठित निकला हुआ किनारा प्रदान किया जाता है। गेंद और वाल्व बॉडी के बीच एक वाल्व सीट स्थापित की जाती है, और वाल्व सीट और बूस्टर मुआवजा वसंत एक रैखिक मुहर बनाते हैं। वाल्व बॉडी के निचले हिस्से को एक छेद के साथ प्रदान किया जाता है, छेद में एक निचला कवर स्थापित किया जाता है, नीचे के कवर की आंतरिक छड़ गोले से जुड़ी होती है, और नीचे के कवर की आंतरिक छड़ और वाल्व बॉडी के बीच एक गैसकेट की व्यवस्था की जाती है।


वायवीय वाल्व का विस्तार निम्नलिखित कारकों पर ध्यान देना चाहिए:

1. Before use, use water to clean the pipeline and the overflow part of the valve body to prevent residual iron filings and other debris from entering the valve body cavity.

2. When the ball valve is closed, there is still a part of the medium remaining in the valve body, and it also bears a certain pressure. Before overhauling the ball valve, close the shut-off valve in front of the ball valve, open the ball valve that needs to be overhauled, and completely release the internal pressure of the valve body. If it is an electric ball valve or a pneumatic ball valve, the power supply and air supply should be disconnected first.

3. Generally, PTFE is used as the sealing material for soft-sealed ball valves, and the sealing surface of hard-sealed ball valves is made of metal surfacing. If the pipeline ball valve needs to be cleaned, care should be taken to prevent damage to the sealing ring and leakage during disassembly.

4. When disassembling and assembling the flanged ball valve, the bolts and nuts on the flange should be fixed first, then all the nuts should be tightened slightly, and finally fixed firmly. If the individual nuts are forcibly fixed first, and then other nuts are fixed, the uneven surface between the flange surfaces will cause damage or rupture of the cushion surface, resulting in the leakage of the medium from the valve flange.

5. If the valve is cleaned, the solvent used must not conflict with the accessories to be cleaned and not corrode. If it is a gas-specific ball valve, it can be cleaned with gasoline. Other parts can generally be washed with reclaimed water. When cleaning, it is necessary to thoroughly clean the residual dust, oil and other attachments. If it cannot be cleaned with clean water, it can be cleaned with alcohol and other cleaning agents on the premise of not damaging the valve body and parts. After the cleaning is completed, wait for the cleaning agent to completely evaporate before assembling.

6. If there is a slight leakage at the packing during use, you can tighten the valve stem nut slightly until the leakage stops, but do not continue to tighten.

7. Long-term storage in the open air will cause the valve body and components to corrode and cannot be used normally. The ball valve should be protected from rain, water, and moisture when stored, and the flange cover should be tightly closed. Valves stored for more than 12 months should be re-tested when used to ensure stable performance.

The control device of the pneumatic ball valve includes a pneumatic bracket, a cylinder, a pin and a sliding sleeve. The pneumatic bracket of the product is connected to the cylinder; the cylinder is provided with a piston rod, the pneumatic bracket is provided with a pneumatic connection handle, and one end of the pneumatic connection handle of the product is provided with an ellipse. The other end is provided with a square groove, the square groove of the product is fixed with the valve rod in the valve body; the pin and the sliding sleeve of the product pass through the oval groove, and are fixed with the piston rod through the circlip provided at the bottom. The beneficial effects of the pneumatic ball valve are as follows: the trouble of processing parts is omitted, the packaging space is small, the raw materials are saved, and the environmental protection is strong.
