消防信號閘閥的構(gòu)造以及材質(zhì)要求

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(yōu)點(diǎn)之外，它還能夠直觀的顯示閘閥門開啟還是關(guān)閉的一個狀態(tài)。下面
川消小編主要簡單帶你了解一下這種產(chǎn)品的構(gòu)造以及材質(zhì)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、整體包膠
1. Overall coating
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(tài)。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(fā)生任何的腐蝕性。
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、采用一提是銅螺母
2. A copper nut is used
為了使得閥芯的銅螺母與球墨鐵骨架之間的聯(lián)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(chǎn)生脫落的可能，所以閥門的控制效果是非常關(guān)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 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、平底式閥座
3. Flat bottom valve seat
采用平底式閥座主要是為了確保雜質(zhì)不會淤堵，不讓流體不通暢的情況發(fā)生。采用平底式閥座，能夠使得管道內(nèi)更加的暢通無阻。
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(jìn)行技術(shù)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(fā)揮，這樣一來，不管是操作還是維護(hù)，閥桿都不會受到壓力沖擊而造成對人員的傷害。
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.
消防信號閘閥因?yàn)楸旧淼淖悦芊庑阅茌^好，結(jié)構(gòu)又比較輕，所以它的使用范圍還是比較廣泛的。除此之外，他對材質(zhì)本身的級別要求還是比較高的，一般采用食品級衛(wèi)生要求。所以閥體采用橡膠完全包裹的同時，不會對系統(tǒng)里面的介質(zhì)產(chǎn)生二次污染的可能。更多相關(guān)事項(xiàng)就來我們網(wǎng)站

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.
