Abstract

This invention is a remote-control motor-driven butterfly valve of online pressure check with a telescopic tube, including a noumenon that is composed of an electric butterfly valve controlling speed-reducing device, a core axis and a valve case. The front stage and the back stage sealing rings in the sub-interlayer added on the butterfly board is mechanically connected, the inter tube of the valve case is mechanically connected with the sealed pressure tube of online check, the two functions of the butterfly valve and the telescopic tube melt together, the two flanges are linked together, the core axis and the butterfly board are mechanically linked, the speed-reducing control is mechanically connected with the core axis, the speed-reducing control and the valve case are mechanically linked, the remote-control device and the motor circuitry are electrically linked. This invention is widely used in the projects of oil field exploration, oil chemistry, coal gas, natural gas, hot electricity, hydraulic power station, steel, tap water, sewage processing, pharmacy and foodstuff. It is especially suitable for the pipelines of river-spanning and the road around the buildings.

Description

The online detected pressures butterfly valve of band telescopic pipe remote control electric
The present invention relates to improved valves on a kind of industrial pipeline, is the thin valve of a kind of body.Butterfly valve on the existing pipeline, as 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, 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 band telescopic pipe remote control electric online detected pressures butterfly valve, butterfly plate has cam action and has eliminated all contact frictions between the Sealing and valve seat in valve stroke, and making it when frequent the keying is the sealing effect of tool all the time.Butterfly valve and telescopic pipe two functions are integrated and save two flanges, secondary seal is installed in the pipeline at valve can online detection sealing load, seal ring contacts with valve seat with certain contact, face is distributed on the valve seat again fully fifty-fifty around centering on it equably, owing to be that valve seat is stressed, therefore valve does not promptly need mechanical position-arresting device when cutting out, and this valve is because special set shape, machine optimal design as calculated, drawing best design parameter makes keying moment reduce to minimum, reaching does not have friction, the desirable purpose of zero leakage, and in manufacture process, carry out special process and handle, have anticorrosive, the characteristics of long service life, circulation area is big, and flow resistance coefficient is little, and structure is tightly played, aesthetic in appearance, the I﹠M of being convenient in light weight, flexible operation, this valve are present desirable update products.Remote control electric control is electrically connected, and the supporting use of motor drive mechanism realizes that remote control, telecontrol are regulated or cut-out rate-of flow purpose.
This product has the following advantages: the online detected pressures butterfly valve of a kind of band telescopic pipe remote control electric, include body, and this body has the control speed reducer, mandrel, valve body mechanical connection, this valve can be isolated fire and be played anti-fire action when closing, be widely used in: oilfield exploitation, chemical industry, petrochemical industry, 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.Fig. 2 is that circuit diagram of the present invention describes details and the working condition that proposes concrete structure according to the present invention in detail below in conjunction with Fig. 1, Fig. 2.
This invention connects mandrel (2) by remote control electric control speed reducer (1), the multi-disc stainless steel synthesizes one group of butterfly plate (3), be fastened on the mandrel (2) by stainless steel bolt, valve body (4) sealing surface and butterfly plate (3) sealing coupling, to reach sealing purpose, the sealing pair interlayer that increases on the butterfly plate, prime sealing (5), final-stage seal (6).Valve body carries out special process in manufacture process handles, take in the valve body (7), connect online detection sealing load pipe (8), butterfly valve and telescopic pipe (9), two functions, the two Ma flange mechanical connections that are integrated, in-line detects sealed at both ends pressure in the pipeline but secondary seal is installed at valve, mandrel and butterfly plate mechanical connection, control speed reducer and mandrel mechanical connection, remote control electric control speed reducer and valve body mechanical connection, remote control electric control is electrically connected, and adapts at cross a river stream and becomes around the existing building thing on the pipeline in roadside on rock limit to use especially.

Claims (1)
