以下是绝缘球阀如下所需的七个主要优点。1.流体电阻小，其电阻系数等于相同长度的管道的电阻系数。2.结构简单，体积小，重量轻。3.紧凑且可靠。目前，具有良好密封性能的塑料材料是优选的作为球阀的密封表面材料。这样的材料也已广泛用于真空系统。4.易于操作，快速打开和关闭。从开口到关闭它的角度仅为90°，这对于遥控是有利的。它很容易保持。球阀的结构非常简单，密封环是可拆卸的。 Therefore, it is more convenient that it can be changed and disassembled. 6. If the insulted ball valve is fully opened or fully closed, the sealing surface can not be eroded when the medium is flow through it. This is because the ball valve body and seat sealing surface are isolated from the medium. 7. The applicable scope is wide. The length range of diameter is from several millimeters to a few meters. It can be applied from high vacuum to high pressure. If the ball body rotates 90 degrees, the sphere can be showed completely in the inlet and outlet so as to block the flow. Insulated ball valve is a relatively new type among ball valve types. The structure has its own superiority, for example the switch is frictionless, the sealing surface is not easy to wear and the open-close torque is small. Then, the specifications of the actuator can be smaller. If it works with multi-turn electric actuators, the medium can be adjusted and cut off. It is widely used in demanding strictly cutting-off operation conditions in petroleum, chemical industry, urban water supply and drainage, etc.

以下是我们需要注意到的弹簧安全阀或弹簧安全阀的一些主要简介安装点。在安装弹簧释放阀之前，我们需要注意的第一件事是务必确定密封性能。如果释放阀泄漏或空腹垫被破坏，则需要相应地改变它们。然后，它可以得到我们所有人的最佳用途。第一前提是，在浮雕阀安装过程中，需要注意垂直安装。并且，安装角度应精确且正式。当然，应该使用工具来制作相应的辅助。然后，它可以平稳且有效地使整个安装过程。其次，应该注意的是，在安装浮雕阀期间，不允许在释放阀的出口上给压力。更好地让它直接空，以便释放阀可以有效地工作。 Then, people can get it best effect, have better use experience and install the relief valve in place. Third, it should be noticed that the operator had better wear the corresponding gloves tools on their hands to avoid that oil pollute relief valve. The oil pollution can affect the sealing effect of relief valve. At same time, it also may lose the whole service life of the relief valve. Therefore, it is a good way to let the operator wear the gloves tools.

门阀是油（气体）井口的主要部件，几种常见故障在使用常见故障时如下。1.闸阀与闸阀结之间的泄漏首先，检查阀门和闸阀连接螺栓是否紧密，如果不拧紧，其密封环和法兰密封槽表面如果没有足够的连接，通常会导致泄漏。检查螺栓和螺母有序，拧紧所有螺栓，直到压缩密封圈。二，检查密封环表面的尺寸和精度和法兰密封槽，如果密封接触面有错误的尺寸或太粗糙，可以修理或更新。另外检查密封环的接触面和法兰密封槽是否存在一点侵蚀，砂孔，砂孔或杂质，或其他缺陷，如果有的话，应携带相应的焊接，修复或清理。2.从发动机罩发动机罩泄漏泄漏，这种故障现象通常发生在包装密封件的泄漏中。首先，检查密封如果配件是正确的，是否适合密封槽，如果存在这样的问题，请更换密封环或修理密封槽。其次，检查密封是否有毛刺，压裂和扭曲，如果有的话，更换密封件。然后，检查密封槽密封的表面是否粗糙或具有其他缺陷，如果存在缺陷，消除缺陷或更新损坏的部件。通过压缩密封填料的帽子或脚手架，应检查包装盒的安装，如果找到倒挂式安装包装，应按照正确的方式进行拆卸。 Pay special attention to the surface of packing seal joint. Finally, check if the precision of the contact surface of seal fittings meet the requirements. 3. Leakage from valve body cavity In the process of casting, sometimes valve body may appear casting defects, such as sand holes, sand hole. Although it is difficult to find in the process of machining, once the pressure put on the valve body, hidden casting defects will be exposed. If there is this kind of situation, welding, repairing or updating it. 4. Leakage from valve seat and valve plate Leakage occurs in valve seat and plate, which is the most common phenomenon among the installation or maintenance of gate valves. Generally this can be divided into two kinds: one is leaking in seal surface; the other is leaking in seal root. Above all, check the seat and the precision of the sealing contact surface of valve plate. The sealing surface needs grinding, if there is rough surface, remove and grind it again. Second, check whether there are pitting, indentation, sand holes, cracks and other defects the sealing surface, if in this case, replace valve seat and valve plate. For the valve seat with compression spring, should check whether the pressure spring elasticity is conform to the requirements, if less resilient, update the compression spring. Besides, check if T-shape coupling place of valve plate and valve ste...
