消防信號閘閥又被稱作是消防專用的一種閘閥，它除了有良好的彈性底座的優點之外，它還能夠直觀的顯示閘閥門開啟還是關閉的一個狀態。但一來他有了直觀的可見度就能夠方便操作人員采取相應的措施，對消防栓進行開啟或者關閉。并且因為這種閘閥的存在，它能夠使得消防系統在啟動的時候更加迅速可靠。所以很多的消防系統當中都會使用這種專用的消防信號閘閥。下面主要簡單帶你了解一下這種產品的構造以及材質要求。

Fire signal gate valve, also known as a fire specific gate valve, not only has the advantage of a good elastic base, but it can also visually display the opening or closing status of the gate valve. But once he has intuitive visibility, he can facilitate operators to take corresponding measures to open or close fire hydrants. And because of the existence of this gate valve, it can make the fire protection system more rapid and reliable when starting. So many fire protection systems use this specialized fire signal gate valve. Below is a brief introduction to the structure and material requirements of this product.

1、整體包膠

1. Overall encapsulation

為了確保這種閘閥高精確度的使用效果，所以對其閥芯是采用一個整體包膠的狀態。這樣一來它能夠使得閥芯更加貼合緊密牢靠，并且不會在流體的沖擊之下發生任何的腐蝕性。

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、采用一提是銅螺母

2. Using copper nuts

為了使得閥芯的銅螺母與球墨鐵骨架之間的聯系更加的緊密，并且長期的操作以及水流沖擊不會讓閥體產生脫落的可能，所以閥門的控制效果是非常關鍵的，一般情況下都采用一體式銅螺母。

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、平底式閥座

3. Flat bottomed valve seat

采用平底式閥座主要是為了確保雜質不會淤堵，不讓流體不通暢的情況發生。采用平底式閥座，能夠使得管道內更加的暢通無阻。

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

不管是閥蓋，還是一些特殊部位的密封要求，為了確保在高壓力情況之下，流體的壓力不會對閥體本身造成傷害，所以它的密封性能要求是非常高的。進行技術改革之后的閥門，不僅能夠確保任何角度的開啟，而且能夠確保閥桿鎖定功能的正常發揮，這樣一來，不管是操作還是維護，閥桿都不會受到壓力沖擊而造成對人員的傷害。

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.
