品牌進(jìn)口斜面球閥認(rèn)準(zhǔn)德國洛克

進(jìn)口斜面球閥結(jié)構(gòu)特點：

1、獨特的結(jié)構(gòu)密封更加可靠斜面球閥又稱“楔式球閥”，采用整體上裝式新型結(jié)構(gòu)。兩閥座密封面設(shè)計成楔形兩斜面，球體上部有一彈簧。在彈簧力的作用下，閥座密封面與球體緊密貼合，形成可靠的密封。

2、閥桿凸肩結(jié)構(gòu)即可防脫又保證了上密封性能閥桿下端設(shè)有凸肩，可在閥體內(nèi)壓異常升高時，防止閥桿脫出。在彈簧及介質(zhì)力的作用下，閥桿   凸肩壓緊墊片，形成上密封效果。

3、先進(jìn)的防火、防靜電結(jié)構(gòu)在球體與閥座之間設(shè)置有防火金屬環(huán)。在意外火災(zāi)閥座燒損后，金屬環(huán)壓在球體上起到密封作用。確保系統(tǒng)的安全，防止重大事故發(fā)生。球體上部的予緊彈簧可將球體與閥座摩擦產(chǎn)生的靜電，經(jīng)導(dǎo)線導(dǎo)入地下。防止因靜電產(chǎn)生的火花點燃易燃易爆介質(zhì)，保證系統(tǒng)的安全。                                  

4、閥門的啟、閉力小，安裝、維修方便閥桿填料函的密封采用填料平面與閥桿凸肩、

閥蓋平面的壓緊，靠彈簧的予緊力及上壓蓋的壓緊力實現(xiàn)密封。減輕了閥門的啟、閉力。閥門采用整體上裝式結(jié)構(gòu)，只須將上部閥蓋拆開，既可取出閥門體內(nèi)全部零件,便于閥門的維修和更換。

Structural features of imported bevel ball valve:

1. Unique structure, more reliable sealing, bevel ball valve also known as "wedge type ball valve", adopts a new structure of integral top mounting. The sealing surface of the two valve seats is designed as wedge and two inclined planes, and there is a spring on the upper part of the ball. Under the action of spring force, the sealing surface of the valve seat closely fits with the ball to form a reliable seal.

2. The shoulder structure of the valve stem can prevent the valve rod from falling off and ensure the upper sealing performance. The lower end of the valve rod is provided with a shoulder, which can prevent the valve rod from falling out when the internal pressure of the valve body is abnormally increased. Under the action of spring and medium force, the shoulder of the valve rod compresses the gasket to form the upper sealing effect.

3. The advanced fireproof and anti-static structure is provided with a fireproof metal ring between the ball and the valve seat. After the valve seat is burnt out in an accidental fire, the metal ring is pressed on the ball to play a sealing role. Ensure the safety of the system and prevent major accidents. The pre tightening spring on the upper part of the ball can lead the static electricity generated by the friction between the ball and the valve seat into the ground through the wire. To prevent the sparks generated by static electricity from igniting flammable and explosive media, and ensure the safety of the system.

4. The valve has the advantages of small opening and closing force, convenient installation and maintenance, and the sealing of the valve stem stuffing box adopts the packing plane and the stem shoulder

The compression of the valve cover plane is realized by the pre tightening force of the spring and the pressing force of the upper gland. The opening and closing force of the valve is reduced. The valve is of integral upper mounting structure, and all parts in the valve body can be taken out by only disassembling the upper valve cover, which is convenient for valve maintenance and replacement.

進(jìn)口斜面球閥參數(shù)：

口徑：DN15～DN200mm

壓力：PN16～PN40Mpa

溫度：-20℃～250℃

材質(zhì)：鑄鋼、不銹鋼

進(jìn)口斜面球閥產(chǎn)品優(yōu)點：

一、耐磨；由于硬密封球閥的閥芯是合金鋼噴焊，三片式球閥 密封圈是合金鋼堆焊，所以硬密封球閥在開關(guān)時不會產(chǎn)生太大的磨損。（它的硬度系數(shù)為65-70）：

二、密封性能好；由于硬密封球閥的密封是采用人工研磨，直到閥芯與密封圈完全吻合才能使用。所以他的密封性能是可靠的。

三、開關(guān)輕；由于硬密封球閥的密封圈底部采用彈簧使密封圈與閥芯緊緊抱在一起，所以在外界力量超過彈簧的預(yù)緊力時開關(guān)非常輕。

四、使用壽命長：已廣泛應(yīng)用于石油、化工、發(fā)電、造紙、原子能、航空、火箭等各部門，以及人們?nèi)粘Ｉ钪?/span>。

進(jìn)口斜面球閥產(chǎn)品簡介：

德國洛克《DE LOCKE》采用楔式上裝型，其球體上施加一壓縮彈簧，壓縮彈簧的作用是在球體上施加預(yù)緊力，使閥座密封面在任何情況下都緊密接觸，密封性能好。閥座與閥體接觸面的楔角為 10°，閥座能夠自鎖，當(dāng)閥座受到較大的壓力時，閥座不會產(chǎn)生任何位移。故這種結(jié)構(gòu)的閥門既有閘閥的特點又有球閥的優(yōu)點。
