消防信号闸阀又被称作是消防专用的一种闸阀，它除了有良好的弹性底座的优点之外，它还能够直观的显示闸阀门开启还是关闭的一个状态。下面川消小编主要简单带你了解一下这种产品的构造以及材质要求。

The fire signal gate valve is also known as a special gate valve for fire protection. In addition to the advantages of good elastic base, it can also visually display the open or closed state of the gate valve. The following is a brief introduction to the structure and material requirements of this product.

1、整体包胶

1. Overall coating

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 use effect of this gate valve, the valve core is in a state of integral gluing. In this way, it can make the valve core more closely and reliably, and will not cause any corrosion under the impact of the fluid.

2、采用一提是铜螺母

2. A copper nut is used

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 framework more close, and the long-term operation and water impact will not make the valve body fall off, so the control effect of the valve is very critical. Generally, the integrated copper nut is used.

3、平底式阀座

3. Flat bottom 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 flat bottom valve seat is mainly used to ensure that impurities will not be clogged and the fluid will not be blocked. The flat bottom valve seat 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。

In order to ensure that the fluid pressure will not damage the valve body itself under high pressure, the sealing performance of the bonnet and some special parts is very high. After the technical reform, the valve can not only ensure the opening at any angle, but also ensure the normal play of the safety locking function of the valve stem. In this way, the valve stem will not be subjected to pressure impact and cause injury to personnel no matter in operation or maintenance.

消防信号闸阀因为本身的自密封性能较好，结构又比较轻，所以它的使用范围还是比较广泛的。除此之外，他对材质本身的级别要求还是比较高的，一般采用食品级卫生要求。所以阀体采用橡胶完全包裹的同时，不会对系统里面的介质产生二次污染的可能。更多相关事项就来我们网站http://www.cx-fire.com咨询吧！

The fire signal gate valve has a wide range of applications because of its good self sealing performance and relatively light structure. In addition, he has relatively high requirements on the level of the material itself, and generally adopts food grade hygiene requirements. Therefore, while the valve body is completely wrapped with rubber, there is no possibility of secondary pollution to the medium in the system.
