產(chǎn)品介紹：利用高精度研磨不銹鋼空心浮球在閥腔內(nèi)隨著凝結(jié)水的液位變化開啟或關(guān)閉閥門

詳細(xì)介紹

產(chǎn)品介紹：

利用高精度研磨不銹鋼空心浮球在閥腔內(nèi)隨著凝結(jié)水的液位變化開啟或關(guān)閉閥門。該疏水閥的結(jié)構(gòu)比較簡(jiǎn)單，主要由浮球和自動(dòng)排空裝置組成。閥腔內(nèi)的動(dòng)作元件——不銹鋼空心浮球，采用高精度研磨工藝制造，整個(gè)球面均可做密封面，工作時(shí)無(wú)集中磨損，使用壽命長(zhǎng) ; 閥腔內(nèi)無(wú)易損件，可靠性高。浮球能根據(jù)水位變化而自由調(diào)節(jié)閥孔的開度，能夠連續(xù)排放凝結(jié)水，過(guò)冷度≈0℃，工作效率高。

自動(dòng)排空裝置分為兩種 :（低壓PN25以內(nèi)）液囊熱敏元件組成和（過(guò)熱蒸汽系統(tǒng)）雙金屬片組成。

Free-ball float trap

The drain valve is opened or closed by taking advantage of the change of liquid level of condensate water with the high-precision grinding stainless steel hollow float ball in the valve cavity. This steam trap has a simple structure, mainly consisting of float balls and automatic emptying devices. The sole action elements, namely, the stainless steel hollow float ball is manufactured by high-precision grinding process, and its entire sphere can serve as the sealing face and will not be worn intensively during the work, so it has a longer service life. In addition, there is no wearing part in the valve cavity, with a high reliability. The float ball can freely adjust the openness of the valve opening in response to the change of water level and discharge the condensate water continuously with a subcooled temperature of about 0℃ and higher efficiency.
The automatic emptying devices fall into two types : (within low pressure PN25) consisting of reservoir thermo-sensitive elements and (overheated steam system) consisting of bimetals.

優(yōu)點(diǎn)：

1、轉(zhuǎn)動(dòng)的是高精度研磨的不銹鋼浮球，抗腐蝕。
2、結(jié)構(gòu)簡(jiǎn)單，維修方便。
3、不受壓力波動(dòng)的影響，連續(xù)排水，噪聲小。
4、裝有自動(dòng)排空裝置，能夠迅速排除空氣，防止氣堵和汽鎖。
5、體積小，排量大。
6、有水就排，能夠加快系統(tǒng)啟動(dòng)速度。

工作原理說(shuō)明：

在設(shè)備剛啟動(dòng)時(shí)，低溫冷凝水和空氣同時(shí)進(jìn)入閥腔，這時(shí)開啟自動(dòng)排空裝置將空氣排除，使低溫凝結(jié)水順利進(jìn)入閥腔，閥腔內(nèi)的凝結(jié)水的液位隨即上升，使浮球升高，開啟閥孔，將凝結(jié)水迅速排出 ; 前面的蒸汽很快進(jìn)入加熱設(shè)備，使設(shè)備迅速加熱升溫，當(dāng)蒸汽或較高溫度的凝結(jié)水進(jìn)入閥腔時(shí)，自動(dòng)排空裝置開始膨脹，關(guān)閉自動(dòng)排空氣裝置，疏水閥開始正常工作。這時(shí)閥腔內(nèi)的浮球隨凝結(jié)水液位的高低而升降，能連續(xù)的排放凝結(jié)水。由于自由浮球式疏水閥的閥座孔總處于凝結(jié)水液位以下，形成水封，水汽自然分離，工作時(shí)達(dá)到無(wú)蒸汽泄漏。該閥的最小工作壓力為0.01Mpa，從0.01Mpa至工作壓力范圍內(nèi)不受溫度和工作壓力波動(dòng)的影響，能連續(xù)工作，其最小過(guò)冷度約為0℃，由于該閥能自動(dòng)、連續(xù)地排除凝結(jié)水，加熱設(shè)備內(nèi)不會(huì)有水積聚，能使加熱設(shè)備達(dá)到理想換熱效率。是生產(chǎn)工藝加熱設(shè)備的理想疏水閥之一。

Description of work principle

When the equipment is just started, the low-temperature condensate and air enter the valve cavity at the same time. At this time, open the automatic evacuation device to remove the air, so that the low-temperature condensate can enter the valve cavity smoothly. The liquid level of the condensate in the valve cavity will rise immediately, so that the floating ball will rise. Open the valve hole, so that the condensate can be discharged quickly. The steam in front of the equipment will enter the heating equipment quickly, so that the equipment can be heated quickly and heated up. When the steam or the temperature is lower than When the high temperature condensed water enters the valve chamber, the automatic emptying device starts to expand, the automatic air exhausting device is closed, and the drain valve starts to work normally. At this time, the floating ball in the valve chamber will rise and fall with the level of condensate, which can discharge condensate continuously. Because the valve seat hole of the free floating ball type drain valve is always below the condensate level, forming a water seal, the water vapor is naturally separated, and there is no steam leakage during operation. The minimum working pressure of the valve is 0.01Mpa, from 0.01Mpa to the maximum working pressure range, it is not affected by the fluctuation of temperature and working pressure, and can work continuously. Its minimum supercooling degree is about 0 ℃. Because the valve can automatically and continuously remove the condensate, there is no water accumulation in the heating equipment, which can make the heating equipment achieve the ideal heat exchange efficiency. It is one of the ideal drain valves for heating equipment of production process.
