進(jìn)口保溫截止閥,(德國(guó)奧萊斯OLES閥門(mén))品牌

【進(jìn)口保溫截止閥】結(jié)構(gòu)原理：

是在閥體焊裝一層金屬夾套，通過(guò)對(duì)金屬夾套內(nèi)注入蒸汽、導(dǎo)熱油、冷卻水、冷氣等，使閥體的介質(zhì)在常溫、升溫、降溫等條件下，達(dá)到所需要的溫度，起到保溫或保冷的作用。保溫閥門(mén)是用在常溫下會(huì)凝固的高粘度、蒸汽或其它保溫、保冷介質(zhì)，確保閥內(nèi)介質(zhì)能夠正常工作。

保溫閥門(mén)具有良好的保溫保冷特性，且閥門(mén)的通徑與管徑*，同時(shí)又能有效降低管路中介質(zhì)熱量損失。具有良好的保溫保冷特性，同時(shí)又能有效降低管路中介質(zhì)熱量損失。保溫閥門(mén)在石油、化工、冶金、制藥等各類(lèi)系統(tǒng)中得到較多應(yīng)用，有效降低管路中介質(zhì)熱量的損失，防止介質(zhì)結(jié)晶、凝固等相象的出現(xiàn)。保溫閥門(mén)的作用是在溫度高或低的情況下通過(guò)閥門(mén)時(shí)，保溫閥門(mén)內(nèi)的物質(zhì)對(duì)介質(zhì)產(chǎn)生保溫效果，使介質(zhì)不會(huì)凝結(jié)或粘在閥體內(nèi)部，讓閥門(mén)的啟閉能正常運(yùn)作。

It is to weld a layer of metal jacket on the valve body. By injecting steam, heat conducting oil, cooling water and air into the metal jacket, the medium of the valve body can reach the required temperature under the conditions of normal temperature, heating and cooling, thus playing the role of heat preservation or cold preservation. Insulation valve is a high viscosity, steam or other insulation and cooling medium which solidifies at room temperature to ensure the normal operation of the medium inside the valve.

The insulation valve has good insulation and cooling characteristics, and the diameter of the valve is the same as the diameter of the pipe. At the same time, it can effectively reduce the loss of medium heat in the pipeline. It has good heat preservation and cooling characteristics, and can effectively reduce the heat loss of medium in the pipeline. Thermal insulation valves are widely used in petroleum, chemical, metallurgical, pharmaceutical and other systems, which can effectively reduce the loss of medium heat in pipelines and prevent the appearance of medium crystallization and solidification. The function of heat preservation valve is to pass through the valve at high or low temperature. The material in the heat preservation valve produces heat preservation effect on the medium, so that the medium will not condense or stick to the inside of the valve body, so that the valve can operate normally.

【進(jìn)口保溫截止閥】工作原理

1）截止閥只許介質(zhì)單向流動(dòng)，安裝時(shí)有方向性。截止閥的結(jié)構(gòu)長(zhǎng)度大于閘閥，同時(shí)流體阻力大，*運(yùn)行時(shí)，密封可靠性不強(qiáng)。

直通式截止閥

2）直流式截止閥：在直流式或Y形截止閥中，閥體的流道與主流道成一斜線(xiàn)，這樣流動(dòng)狀態(tài)的破壞程度比常規(guī)截止閥要小，因而通過(guò)閥門(mén)的壓力損失也相應(yīng)的小了。

3）角式截止閥：在角式截止閥中，流體只需改變一次方向，以致于通過(guò)此閥門(mén)的壓力降比常規(guī)結(jié)構(gòu)的截止閥小。

4）柱塞式截止閥：這種形式的截止閥是常規(guī)截止閥的變型。在該閥門(mén)中，閥瓣和閥座通常是基于柱塞原理設(shè)計(jì)的。閥瓣磨光成柱塞與閥桿相連接，密封是由套在柱塞上的兩個(gè)彈性密封圈實(shí)現(xiàn)的。兩個(gè)彈性密封圈用一個(gè)套環(huán)隔開(kāi)，并通過(guò)由閥蓋螺母施加在閥蓋上的載荷把柱塞周?chē)拿芊馊豪巍椥悦芊馊δ軌蚋鼡Q，可以采用各種各樣的材料制成，該閥門(mén)主要用于“開(kāi)”或者“關(guān)”，但是備有特制形式的柱塞或特殊的套環(huán)，也可以用于調(diào)節(jié)流量。
