主要性能 Main performance

(燃气)进口导热油，蒸汽柱塞阀关闭时阀杆将柱塞插入下密封环，如同将瓶塞塞入瓶口一样。无论您用多大的力量旋动手轮，都不会影响柱塞与密封环之间的密封力，它们之间仍然保持着装配时予紧的程度，开关柱塞阀时，柱塞在密封环中只做缓慢移动，柱塞与密封环的接触面几乎不磨损 RETZ Heat transfer oil: when the steam plunger valve is closed, the valve rod will insert the plunger into the lower sealing ring, just like plugging the bottle stopper into the bottle mouth. No matter how hard you rotate the handwheel, the sealing force between the plunger and the sealing ring will not be affected. They still maintain the pre tightening degree during assembly. When opening and closing the plunger valve, the plunger only moves slowly in the sealing ring, and the contact surface between the plunger and the sealing ring is hardly worn

(燃气)进口导热油，蒸汽柱塞阀特点∶ Performance characteristics

1.柱塞插入两只密封环中。插入下面一只密封环，截断了流道，实现了可靠的关闭。开启时，柱塞在虽然脱离下密封环，但仍然留在上密封环中，保持与外界隔离，不致发生泄漏 RETZ The plunger is inserted into the two sealing rings. Insert a sealing ring below to cut off the flow channel and realize reliable closing. During opening, although the plunger is separated from the lower seal ring, it remains in the upper seal ring to keep isolated from the outside and avoid leakage

2.流体中细微杂质不会伤害柱塞阀。当关闭阀门时，柱塞进入密封环中，会将流体中的悬浮微粒扫出去 Fine impurities in the fluid will not damage the plunger valve. When the valve is closed, the plunger enters the sealing ring, which will sweep out the suspended particles in the fluid

3.具有科学合理的结构及良好的密封性能，使用中几乎不需要保养 It has a scientific and reasonable structure and good sealing performance, and hardly needs maintenance in use

4.密封环是柱塞阀的关键零件，可以在摄氏-10℃-300℃的条件下连续使用而不会失效。它是由高强度极限、耐高温、耐腐蚀、耐磨损、无毒、经受长期高压高温而不丧失弹性且能保持稳定尺寸的复合材料所制造。主要含有聚四氟乙烯、石墨及高弹性胶等 The sealing ring is a key part of the plunger valve. It can be used continuously at - 10 ℃ - 300 ℃ without failure. It is made of composite materials with high strength limit, high temperature resistance, corrosion resistance, wear resistance, non-toxic, long-term high pressure and high temperature without losing elasticity and maintaining stable size. It mainly contains polytetrafluoroethylene, graphite and high elastic rubber

5.柱塞阀久用之后出现渗漏，此时应将阀门关闭（关到底），然后按对角方式轮换着稍为拧紧阀盖上的螺母，直到渗漏现象消除为止。注意!千万不可将螺母一次性的拧到底。假如柱塞阀久用之后出现渗漏，此时应将阀门关闭（关到底），然后按对角方式轮换着稍为拧紧阀盖上的螺母，直到渗漏现象消除为止RETZ If the plunger valve leaks after long-term use, the valve shall be closed (closed to the end), and then the nuts on the valve cover shall be slightly tightened in a diagonal manner until the leakage phenomenon is eliminated. be careful! Never screw the nut all at once. If the plunger valve leaks after long-term use, the valve should be closed (closed to the end), and then slightly tighten the nut on the valve cover in a diagonal manner until the leakage phenomenon is eliminated
