Abstract
The invention relates to an advanced valve used in industrial pipelines. The remote controlled high-temperature and highly corrosion resistant butterfly valve is a thin valve which can resist the high temperature no more than 450deg.C and especially the strong phosphoric acid added to particles with rigidity less than 316L. It is widely applied to: coal gas, natural gas, thermoelectricity, hydraulic power plant, steel, municipal construction, sewage disposal, pharmacy, food and other projects and especially to the pipeline transportation.
Description
The present invention relates to improved valves on a kind of industrial pipeline, be that a kind of body approaches and a kind of butterfly valve of ability≤540 ℃ high temperature liquid, butterfly valve on the existing pipeline, as slim line with rubber, lining fluorine butterfly valve because of sealing material ability temperature liquid more than 120 ℃ not, can only limit below 120 ℃ and use, as residue is arranged in the pipeline transport, granular, flow velocity is fast, has crashed through sealing material, can not seal, very heavy because of other gate valve weight, 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 distance type high temperature high corrosion resistant butterfly valve is provided, three eccentric multi-level stainless steel metal sealings are paid, high temperature resistant, the butterfly valve of high-corrosion resistant is in the wafer type valve body, the sealing that increases on the butterfly plate of mandrel butterfly plate mechanical connecting structure is paid and is selected stainless steel material for use, butyl folder graphite layer is also carried out special process and is handled in manufacture process, have high temperature resistant, anticorrosive, the characteristics of long service life, the liquid that adapts to low middle pressure impacts, and circulation area is big, and flow resistance coefficient is little, compact structure, aesthetic in appearance, volume is little, and is in light weight, hoisting capacity is apart from reducing to minimum, be convenient to I﹠M, flexible operation, this valve are the update products that substitutes gate valve and stop valve, except that manually with any electronic, pneumatic, the supporting use of mechanism such as surge realizes remote control regulating and controlling or cut-out-rate-of flow purpose.
This product has the following advantages: a kind of distance type high temperature high corrosion resistant butterfly valve, include body, this body has the control speed reducer, mandrel, the valve body mechanical connection, become one group of sealing to pay a butterfly plate to be connected on the mandrel with stainless steel and butyl horsestone China ink is laminated with bolt machinery, characteristics with corrosion-and high-temp-resistant, butterfly plate has cam action and except all contact frictions between Sealing in valve stroke and the valve seat, making it frequent keying is the sealing effect that still has all the time, seal ring contacts with valve seat with certain wrapping angle, face is equivalent to an elongated wedge again around centering on it equably, and make active force be evenly distributed on the valve seat fully, owing to be that valve seat is stressed, therefore valve does not promptly need mechanical position-arresting device when cutting out, and Vidacare corp and configuration are to the interface and the signaling interface of accepting the central control chamber remote control of Central Control Room transmission state signal.
Can high temperature resistantly corrode with height with 316L, 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 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.
Fig. 2 is a circuit diagram 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), wafer type valve body (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.Vidacare corp and configuration realize the remote control regulating and controlling to the interface and the signal (5) of accepting the central control chamber remote control of Central Control Room transmission state signal.
Claims (1)
- A kind of distance type high temperature high corrosion resistant butterfly valve, by the control speed reducer, connect mandrel, one group of butterfly plate, compositions such as wafer type valve body, it is characterized in that: control speed reducer and mandrel mechanical connection, control speed reducer and wafer type valve body mechanical connection, become one group of sealing to pay a butterfly plate to be connected on the mandrel with stainless steel and butyl horsestone China ink is laminated with bolt machinery, butterfly plate has cam action and except all contact frictions between Sealing in valve stroke and the valve seat, seal ring contacts with valve seat with certain wrapping angle, face is equivalent to an elongated wedge again around centering on it equably, and making active force be evenly distributed in fully on the valve seat, Vidacare corp and configuration are electrically connected with the signaling interface of accepting the central control chamber remote control to the interface of Central Control Room transmission state signal.
