概述

彈性座封閘閥采用特種橡膠全包裹整體式彈性閥瓣，可在壓力下產(chǎn)生微量的彈性變形，利用其與閘座的自適應(yīng)性補(bǔ)償作用，達(dá)到良好的密封效果。克服了它們傳統(tǒng)閘閥密封不良，內(nèi)件閥瓣易銹蝕，橡膠彈性疲乏易老化，且操作費(fèi)力，維修不便等缺陷。可廣泛用于洪水、石化、冶金、船舶、食品醫(yī)藥及能源系統(tǒng)等流體管路上作為調(diào)節(jié)和截流裝置使用。

Overview

Flexible seat seal gate valve is fully wrapped by special rubber.Pro-vided with

integral flexible valve core,it is away from water leakage or rusting compared

with ordinary gate valve,and the ubiquitous problems of bad seal,elasticity fat

igue,aging of ruber and abrasion and rusting of sealing surface.lt makes full u

se of the compensation function of micro distortion produced by flexible seal to

actualize good sealing effect.This valve is widely used in fluid pipeline in the

fields of water supply,petrochemicals,metallurgy,shipping,foodstuff,

pharmaceuticals and en-ergy sources,functioned to adjust and cut off flow.

特點(diǎn)

1、整體包膠：閥芯采用高性能橡膠和的硫化技術(shù)進(jìn)行整體包裹，貼合緊密牢固，幾何尺寸精確，密封可靠，使用壽命長(zhǎng)，操作輕快，維修簡(jiǎn)單便利。

2、重量輕：閥體球墨鑄鐵材料，重量較一般閘閥減輕25%，安裝維修方便；閥門(mén)打開(kāi)高度較一般閘閥低60mm~280mm，可安裝有空間限制的場(chǎng)合。

3、平底式閥座：底部采用與管道相同的平底式閥座設(shè)計(jì)，不會(huì)產(chǎn)生雜物堆積，流道暢通無(wú)阻且密封可靠。

4、耐蝕性能：閥門(mén)內(nèi)腔采用無(wú)毒環(huán)氧樹(shù)脂粉末途裝，內(nèi)件采銅合金和不銹鋼可防止腐蝕和生銹，不但可用于飲水、食品等系統(tǒng)，而且可用于污水或地下等系統(tǒng)中。

5、三“O"密封：閥桿上密封處采用O型圈密封，摩擦阻力小，開(kāi)關(guān)輕巧不漏水。

Features

Fully Rubber Wrapped:valve core fully wrapped by high perfor-mance rubber and

latest vulcanization technology closely and firmly to effect accurate geometrical

dimensions,dependable seal and long ser-vice life.

Lightweight:valve gody made of spheroidal graphite cast iron mate-rial,25% lighter

compared with ordinary gate valve,easy installation and servicing;maximum opening

height 60mm~280mm lower than or-dinary gate valves,they may be mounted in

spacerestricted locations.

Flat-bottomed Valve Seat:design of flat-bottomed valve seat,which is the same as

that of pipeline,will not result in sundries deposited,thus to effect smooth flow

channel and reliable seal.

Corrosion-resisting Performance:the chamber of valve is coated by nontoxic epoxy resin

powder,and the internal parts are made of copper alloy and stainless steel to

avoid corrosion and rusting.This product is not only applicable for drinking water

and foodstuff system,but also applicable for sewage and underground system.

３＂Ｏ＂Seals:The upper seal of valve stem uses O-ring for small abra-sion resistance,handy open-close and leak-tightness.
