消防信号闸阀的构造以及材质要求

来源：http://www.cx-fire.com/ 日期：2024-04-23

1、整体包胶

1. Overall encapsulation

为了确保这种闸阀高精确度的使用效果，所以对其阀芯是采用一个整体包胶的状态。这样一来它能够使得阀芯更加贴合紧密牢靠，并且不会在流体的冲击之下发生任何的腐蚀性。

In order to ensure the high-precision performance of this gate valve, the valve core is in a fully encapsulated state. In this way, it can make the valve core more tightly and firmly attached, and will not cause any corrosion under the impact of the fluid.

2、采用一提是铜螺母

2. Using copper nuts

为了使得阀芯的铜螺母与球墨铁骨架之间的联系更加的紧密，并且长期的操作以及水流冲击不会让阀体产生脱落的可能，所以阀门的控制效果是非常关键的，一般情况下都采用一体式铜螺母。

In order to make the connection between the copper nut of the valve core and the ductile iron skeleton more tight, and to prevent the possibility of valve body detachment due to long-term operation and water flow impact, the control effect of the valve is crucial. Generally, integrated copper nuts are used.

3、平底式阀座

3. Flat bottomed valve seat

采用平底式阀座主要是为了确保杂质不会淤堵，不让流体不通畅的情况发生。采用平底式阀座，能够使得管道内更加的畅通无阻。

The use of flat bottomed valve seats is mainly to ensure that impurities do not clog and prevent the occurrence of fluid blockage. The use of flat bottomed valve seats can make the pipeline more unobstructed.

4、良好的密封性能

4. Good sealing performance

不管是阀盖，还是一些特殊部位的密封要求，为了确保在高压力情况之下，流体的压力不会对阀体本身造成伤害，所以它的密封性能要求是非常高的。进行技术改革之后的阀门，不仅能够确保任何角度的开启，而且能够确保阀杆锁定功能的正常发挥，这样一来，不管是操作还是维护，阀杆都不会受到压力冲击而造成对人员的伤害。

Whether it is the valve cover or the sealing requirements of some special parts, in order to ensure that the fluid pressure will not cause damage to the valve body itself under high pressure conditions, its sealing performance requirements are very high. After technological reform, valves can not only ensure opening at any angle, but also ensure the normal functioning of the safety locking function of the valve stem. This way, whether it is operation or maintenance, the valve stem will not be subjected to pressure impact and cause harm to personnel.
