Abstract
The invention relates to a flange high-temperature and highly corrosion resistant butterfly valve used in industries is a thin valve which can resist the high temperature no more than 600deg.C. It is featured by corrosion resistance and long useful life and is adaptable to the impingement from the liquid with low-middle pressure. It is featured by large circulation area, small coefficient of flow resistance, compact structure, beautiful appearance, light weight, minimum open and close moment, simple installation and maintenance and flexible operation and can replace the gate valve and the break valve. It can form a complete set with any dynamoelectric and pneumatic mechanisms, except for the hand operated mechanisms, to realize the goals of remote control and adjustment or shutting off one medium. It is widely applied to: oil extraction, chemical industry, petrifaction, coal gas, natural gas, thermoelectricity, hydraulic power plant, steel, municipal construction, tap water, sewage disposal, pharmacy, food and other projects and especially to the pipeline transportation.
Description
The present invention relates to improved valve on a kind of industrial pipeline, be that a kind of body approaches and the valve of ability≤600 ℃ high temperature liquid, a kind of butterfly valve of particularly being able to bear strong corrosion, butterfly valve on the existing pipeline, as slim line with rubber, lining fluorine gate valve, because of sealing material ability temperature liquid more than 120 ℃ not, can only limit below 120 ℃ and use, as residue, granular are arranged in the pipeline transport, flow velocity is fast, crashed through sealing material, can not seal, because of other gate valve weight very heavy, can not on suspended piping, install, as install and must design a lot of supports, waste a large amount of metals and structural material and man-hour, and influenced the traffic under the pipeline.
The objective of the invention is: a kind of flange-type high temperature high corrosion resistant butterfly valve is provided, have high temperature resistant, anticorrosive, the characteristics of long service life, adapt to the impact of the liquid of low middle pressure, circulation area is big, and flow resistance coefficient is little, compact structure, aesthetic in appearance, in light weight, hoisting capacity is convenient to I﹠M apart from reducing to minimum, flexible operation, this valve is the update product that substitutes gate valve and stop valve, remove manually with any electronic, pneumatic, etc. the supporting use of mechanism, adjusting of realization telecontrol or cut-out-rate-of flow purpose.
The present invention has the following advantages: a kind of flange-type high temperature high corrosion resistant butterfly valve, include body, this body has the control speed reducer, mandrel, the valve body mechanical connection, mandrel butterfly plate mechanical connection, the sealing that increases on the butterfly plate are paid and are selected stainless steel material for use, and butyl folder graphite layer is also carried out special process and handled in manufacture process.
This valve can isolate fire and play anti-fire action when cutting out, be widely used in: oilfield exploitation, chemical industry, petrochemical industry, coal gas, rock gas, thermoelectricity, water power plant, iron and steel, urban construction, tap water, sewage treatment, pharmacy, engineerings such as food are particularly used on the pipeline transport engineering.
The present invention is easy to use, exchange to install lightly, and when gate valve and the stop valve under same specification pressure and material during embodiment below adopting, its weight only is 1/3 of gate valve and stop valve, so has reduced cost greatly.
Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.Describe details and the working condition that proposes concrete structure according to the present invention in detail below in conjunction with Fig. 1, this invention connects mandrel (2) by control speed reducer (1), make with stainless steel material, the synthetic one group of butterfly plate (3) of multi-disc stainless steel folder butyl graphite flake, be fastened on the mandrel (2) by stainless steel bolt, flange-type valve body (4) sealing surface and butterfly plate (3) sealing coupling, to reach sealing purpose, and three off-centre not fixedly the stop bit device just can seal, the special adaptation in the roadside, often use on the pipeline on the ground environment of vibrations.
Claims (1)
- A kind of flange-type high temperature high corrosion resistant butterfly valve, by the control speed reducer, connect mandrel, one group of butterfly plate, compositions such as flange-type valve body, it is characterized in that: mandrel and valve body mechanical connection, mandrel and butterfly plate mechanical connection, the sealing that increases on the butterfly plate are paid and are selected stainless steel material for use, and butyl folder graphite layer is also carried out special process and handled in manufacture process, control speed reducer and mandrel mechanical connection, control speed reducer and flange-type valve body mechanical connection.
