01電動(dòng)O型球閥概述

Q941F電動(dòng)O型球閥是常見(jiàn)的開(kāi)關(guān)型控制關(guān)斷閥，即工作方式為全開(kāi)或全關(guān)的兩位式狀態(tài)，由于球閥閥芯采用O型結構，顧被稱(chēng)為電動(dòng)O型切斷球閥。電動(dòng)開(kāi)關(guān)球閥只需通入220VAC電源即可完成開(kāi)關(guān)動(dòng)作，特別適用于各種壓差大等快速開(kāi)關(guān)、切斷的管道當中。

Q941F electric O-type ball valve is a common on-off control shut-off valve, that is, the working mode is a two position state of full open or full close. Because the valve core of the ball valve adopts the O-type structure, Gu is called the electric O-type shut-off ball valve. The electric switch ball valve only needs to be connected to the 220VAC power supply to complete the switch action, which is especially suitable for quick switch and cut-off pipelines with large pressure difference.

02電動(dòng)O型球閥產(chǎn)品特點(diǎn)

1.唇形設計

想要讓密封材料像橡膠一樣，受壓時(shí)可以發(fā)生較大的變形，來(lái)填補金屬表面的微觀(guān)不平度，而當應力消除后又能恢復其原來(lái)的形狀，這種現象被稱(chēng)為材料的“記憶特性”所以我們的目的，就是要設計一種密封座的形狀，克服PTFE的“冷流”和熱膨脹特性的缺陷來(lái)改善其記憶特性。這種密封結構稱(chēng)之為具有撓性的唇式密封技術(shù)。

2.雙層密封結構

由于閥座是唇形設計，在初始密封時(shí)是下點(diǎn)密封，當壓力升高閥座唇形位置變形，形成兩點(diǎn)密封，使密封性能更加可靠。

3.背壓變形結構

閥座背面有一定的弧度來(lái)減小直角變形的缺點(diǎn)，同時(shí)使唇形閥座具有優(yōu)良的彈性性能。

4.外形變形結構

閥座外圓上作出一定的弧度角，用來(lái)防止唇形閥座變形帶來(lái)的擠壓應力過(guò)大。

1. Lip shape seal design The rubber will occur large deformation under pressure to offset the roughness of metal surface, and can recover its original shape when stress relief. This material is called as"Memory Property". We plan to create a new seat material that can overcome the defects of PTFE cold flow and thermal expansion and improve the memoryproperty. This sealing structure is called as Lucky Lip Seal Technology.

2. Double layers sealing structure The lip shape seal seat has the advantages that its position will be changed due to high temperature, which will form double points sealing, sealing performance is more reliable.

3. Backpressure deformation structure There is a certain radian on the back side of the seat to prevent the right angle from being deformed, and it also can improve the lip shape seal seat elasticity.

4. Shape deformation structure The radian angle on the seat mainly avoid the higher extrusion stress occurred because of the deformation of the lip shape seal seat.

04電動(dòng)O型球閥適用場(chǎng)景

Q941F電動(dòng)O型球閥特別適用于介質(zhì)是黏稠、含顆粒、纖維性質(zhì)的場(chǎng)合，目前該電動(dòng)開(kāi)關(guān)球閥廣泛用于石油、化工、冶金、輕工、造紙、電站、制冷等工作領(lǐng)域。

Applicable scenarios:

Q941F electric O-type ball valve is especially suitable for the occasions where the medium is viscous, containing particles and fiber. At present, the electric switch ball valve is widely used in the fields of petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration, etc.
