進(jìn)口柱塞截止閥歐美品牌德國洛克

進(jìn)口柱塞截止閥結(jié)構(gòu)特點(diǎn)：

進(jìn)口柱塞截止閥是由閥體、閥蓋、閥桿、柱塞、導(dǎo)向、密封環(huán)、手輪等零件組成。當(dāng)手輪旋轉(zhuǎn)時(shí)，通過閥桿帶動柱塞在導(dǎo)向套中上、下往復(fù)運(yùn)動，使柱塞端部斜錐面與閥座錐面完成閥門的開啟與關(guān)閉功能。在閥門中柱塞與密封環(huán)間采用過盈配合，通過調(diào)節(jié)中法蘭螺栓預(yù)緊力，使密封環(huán)壓縮所產(chǎn)生的側(cè)向力與閥體中孔面柱塞外圓密封，從而保證了閥門的密封性。杜絕了內(nèi)泄漏。由于密封環(huán)采用回彈性強(qiáng)、耐磨性高的無毒新型密封材料，所以密封可靠、經(jīng)久耐用，從而提高了閥門的使用壽命。

進(jìn)口柱塞截止閥工作原理：

進(jìn)口柱塞截止閥當(dāng)手輪旋轉(zhuǎn)時(shí)，通過閥桿帶動柱塞在孔架中間上下往復(fù)運(yùn)動來完成閥門的開啟與關(guān)閉功能。在閥門中柱塞與密封環(huán)間采用過盈配合，通過調(diào)節(jié)壓蓋中法蘭螺栓，使密封環(huán)壓縮所產(chǎn)生的側(cè)向力與閥體中孔面及柱塞外圓密封，從而保證了閥門的密封性。

Working principle of inlet plunger stop valve:
When the handwheel rotates, the valve stem drives the plunger to move up and down in the middle of the hole frame to complete the opening and closing functions of the valve. The interference fit is used between the plunger and the sealing ring in the valve. By adjusting the flange bolt in the gland, the lateral force produced by the compression of the sealing ring and the sealing of the hole surface and the outer circle of the column plug in the valve body are made, thus ensuring the sealing performance of the valve.

進(jìn)口柱塞截止閥產(chǎn)品簡介：

柱塞截止閥的關(guān)閉由一個(gè)不銹鋼柱塞、上下兩只密封圈及一個(gè)金屬隔框組成，密封效果由柱塞與密封圈緊密配合來達(dá)到，柱塞插在兩只密封圈中，密封面積遠(yuǎn)大于普通截止閥；開關(guān)柱塞閥時(shí)，柱塞在密封圈中緩慢移動，接觸面幾乎不磨損，關(guān)閉時(shí)，柱塞插入下密封圈，截?cái)嗔鞯?；開啟時(shí)，柱塞雖然脫離下密封圈，但仍藏在上密封圈內(nèi)，保持與外界隔離，不致發(fā)生泄漏。

Introduction of imported plunger globe valve products:
The closing of the plunger stop valve is composed of a stainless steel plunger, two elastic sealing rings and a metal partition frame. The sealing effect is achieved by the close cooperation between the plunger and the sealing ring. The plunger is inserted in the two sealing rings, and the sealing area is much larger than that of the ordinary stop valve. When the plunger valve is opened and closed, the plunger moves slowly in the sealing ring, and the contact surface is hardly worn. When it is closed, the plunger is inserted When the plunger is opened, although the plunger is separated from the lower sealing ring, it is still hidden in the upper sealing ring to keep isolated from the outside and avoid leakage.
