Abstract
The invention relates to an improved thin-body valve capable of resisting the fluid with high-temp. less than and equal to 455 deg.c.. A control reduction gear of the butterfly valve capable of resisting strong corrosion is mechanically connected with a dabber. The control reduction gear is also mechanically connected with the casing and the inlet-outlet connector means welded and casted outside the flange valve body.
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≤455 ℃ high temperature liquid, particularly strong phosphoric acid adds a kind of butterfly valve of being able to bear strong corrosion of the low 316L hardness of hardness of particle, 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: provide a kind of three eccentric multi-level 316L metallic seals to pay, high temperature resistant, the butterfly valve of high-corrosion resistant, burn-on or cast in heat-preservating shell and the turnover connecting tube device in that flange valve is external, the sealing that increases on the butterfly plate of mandrel butterfly plate mechanical connecting structure is paid and is selected 316L for use, pneumatic, the supporting use of mechanism such as surge realizes that telecontrol regulates or cut-out-rate-of flow purpose.
This product has the following advantages: a kind of flange high temperature insulating high corrosion resisting butterfly valve, include body, and this body has the control speed reducer, mandrel, valve body is burn-on outward or is cast heat-preservating shell and the connection of turnover connecting tube device for mechanical, high temperature resistant and high corrosion the with the 316L energy, and 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 light and handy, when same specification (more than the medium specification) during embodiment below adopting, gate valve under pressure and the material and stop valve, 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 the 316L material, the synthetic one group of butterfly plate (3) of multi-disc 316L folder butyl graphite flake, by the 316L bolton on mandrel (2), flange valve is external burn-ons or casts heat-preservating shell and turnover connecting tube device (4) sealing surface and butterfly plate (3) sealing coupling, reaching 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 high temperature insulating high corrosion resisting butterfly valve, by the control speed reducer, connect mandrel, one group of butterfly plate, flange valve is external burn-ons or casts compositions such as heat-preservating shell and turnover connecting tube device, it is characterized in that: control speed reducer and mandrel mechanical connection, control speed reducer and flange valve be external burn-ons or casts heat-preservating shell and pass in and out the connecting tube device for mechanical and be connected, make with the 316L material, the synthetic one group of butterfly plate of multi-disc 316L folder butyl graphite flake, by the 316L bolton on mandrel, flange-type valve body, sealing surface and butterfly plate sealing coupling.
