產(chǎn)品特點：
對夾中線蝶閥主要由閥體、轉(zhuǎn)軸、閥板、閥座及驅(qū)動機(jī)構(gòu)（手柄、蝸輪蝸桿、氣動裝置或電動裝置）等組成，靠驅(qū)動機(jī)構(gòu)帶動轉(zhuǎn)軸及閥板旋轉(zhuǎn)以實現(xiàn)啟閉和控制流量的目的。對夾式蝶閥特點如下：
結(jié)構(gòu)簡單、小巧輕便，運(yùn)輸、安裝、拆卸容易;90°啟閉，開關(guān)迅速。操作扭矩小，省力輕巧;密封性能好，使用壽命長，可達(dá)到零泄漏;選擇不同的零部件材質(zhì)，可適用于多種介質(zhì);流量特性近似于直線，調(diào)節(jié)性能好。
abutterfly valveconsists of body ,stem ,disc ,actuator (manual actuator, worm-gear actuator , aerodynamicactuator or electric actuator) , andwafer type butterflyvalvecan implement the process for turning on turning offand regulating the flow by the circumrotation of stem and disc thatis droved by actuators.
1.simple and compact construction. small in size and light inweight. easy transportation , installation and maintenance.
2. quick 90 degrees on-off operation. minimized operating torque,energy saving.
3. excellent sealing performance with no leakage. long servicelife.
4. wide selection of materials ,applicable for various media..
5. flow curve tending to straight line. excellent regulationperformance.

注：1、dn50~dn800蝶閥分別適用于pn1.0/pn1.6mpa兩種壓力級，表中每規(guī)格中有兩個尺寸的分別表示pn1.0mpa和pn1.6mpa兩種壓力級連接尺寸。蝶閥上法蘭可通用于手動、蝸輪蝸桿傳動、電動、氣動等。表中d1及n-?尺寸為蝶閥安裝定位尺寸，包容國標(biāo)（gb）、（iso）、德標(biāo)（din）、英標(biāo)（bs）等法蘭連接標(biāo)準(zhǔn)。

2、d1及n-?尺寸可按國標(biāo)（gb）、（iso）、美標(biāo)（ansi）、德標(biāo)（din）、英標(biāo)（bs）、日標(biāo)（jis）加工生產(chǎn)。e及n1-?1尺寸可按gb/t12223及iso 5211標(biāo)準(zhǔn)加工生產(chǎn)。

note: 1、dn50~dn800 butterfly valves are suitablefor the pressure of pn1.0 and pn1.6mpa grade separately. twodimensions in one size show the connection dimensions ofpn1.0/pn1.6mpa pressure grade. the upper flanges of the valves aresuitable all types of valves fitted with electric, worm gear,manual, pneumatic and actuators. the dimensions d1 and n-? arelisted in above table show the installation dimensions of butterflyvalve. it contains china standard (gb), international standard(iso), germany standard (din), and england standard (bs) of flangeconnection standard, etc.

2、the dimensions of d1 and n-? ones aremanufactured according to china standard (gb), internationalstandard (iso), american standard (ansi), germany standard (din),england standard (bs), and japan standard (jis). the dimensions ofe and n1-?1 ones are manufactured according to gb/t 12223 and iso5211 standard.
