1.良工閥門連接是一種廣泛使用的閥門連接方式。依據(jù)組合面的形狀,可分為:光滑型:適用于低壓閥;易加工凹凸:工作壓力大,可采用中硬墊圈榫槽形式:可采用塑性變形大的墊圈,廣泛用于腐蝕性介質(zhì),密封效果好。梯形槽式:采用橢圓金屬環(huán)作墊圈,適用于壓力大于64kg/cm2的閥門或高溫閥門。鏡面型:襯墊是由金屬制成的透鏡狀。適用于壓力大于100公斤/平方厘米的高壓閥或高溫閥。O型圈:這是一種較新的法蘭連接形式,隨著各種橡膠O型圈的出現(xiàn)而發(fā)展起來,它比普通平墊更可靠。
1. Lianggong valve connection is a widely used valve connection mode. According to the shape of the combination surface, it can be divided into: smooth type: suitable for low-pressure valve; Easy to process concave convex: high working pressure, medium hard gasket tenon groove form can be adopted: gasket with large plastic deformation can be adopted, which is widely used in corrosive media and has good sealing effect. Trapezoidal groove type: oval metal ring is used as gasket, which is suitable for valves with pressure greater than 64kg / cm2 or high temperature valves. Mirror surface type: the liner is a lens made of metal. It is applicable to high-pressure valve or high-temperature valve with pressure greater than 100 kg / cm2. O-ring: This is a relatively new form of flange connection. It has developed with the emergence of various rubber O-rings. It is more reliable than ordinary flat gaskets.

2.夾緊連接采用螺栓直接夾緊閥門與兩端管路。
2. The clamping connection adopts bolts to directly clamp the valve and the pipelines at both ends.
3.對焊良工閥門連接。
3. Butt welding good worker valve connection.
4.這是一種簡單的連接方式,通常用于小良工閥門。二種情況:直接密封:內(nèi)外螺紋直接起密封作用。為保障接頭不漏水,常采用鉛油、線麻、聚四氟乙烯生料帶填充,其中聚四氟乙烯生料帶應(yīng)用廣泛,耐腐蝕,密封效果優(yōu)良,使用及保存方便。拆開時可完全取出,因為是無粘性膜,比鉛油、線麻要好得多。間歇封:將螺紋上緊的力傳給兩平面之間的墊圈,使墊圈起密封作用。
4. This is a simple connection method, which is usually used for small good worker valves. Two cases: direct sealing: internal and external threads directly play a sealing role. In order to ensure that the joint is watertight, lead oil, hemp and PTFE raw material belt are often used for filling. Among them, PTFE raw material belt is widely used, corrosion-resistant, excellent sealing effect and convenient for use and storage. It can be completely taken out when disassembled, because it is a non adhesive film, which is much better than lead oil and hemp. Intermittent sealing: transmit the tightening force of the thread to the washer between the two planes to make the washer seal.
5.夾套連接在我國近幾年出現(xiàn)。它的聯(lián)接與密封原理是,當(dāng)螺母擰緊時,夾套受壓,使其刃口咬進管道外壁,夾套的錐面在受壓作用下與接頭體內(nèi)的錐面密封,可可靠防止泄漏。
5. Jacket connection has appeared in China in recent years. Its connection and sealing principle is that when the nut is tightened, the jacket is pressurized to make its edge bite into the outer wall of the pipe, and the conical surface of the jacket is sealed with the conical surface in the joint body under pressure to prevent leakage.
