Abstract
This invention is a opposite-clamping butterfly valve of manual online pressure check. It includes the noumenon which is made up of manual control device, the core axis and the opposite-clamping 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 core axis and the butterfly board are mechanically linked, the manual control device and the core axis are mechanically linked, and the control device is mechanically connected with the valve case. 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 pipe of small caliber.
Description
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: a kind of manual online measuring pressure wafer type butterfly valve is provided, and 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.Secondary seal is installed at valve can online detection sealing load in the pipeline.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.
This product has the following advantages: a kind of manual online measuring pressure wafer type butterfly valve, include body, and this body has manual overvide, mandrel, wafer type 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, 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 1/4 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 manual overvide (1), the multi-disc stainless steel synthesizes one group of butterfly plate (3), be fastened on the mandrel (2) by stainless steel bolt, wafer type 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 wafer type valve body (7), connect online detection sealing load pipe (8), 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 gear and mandrel mechanical connection.Manual overvide and valve body mechanical connection, the special adaptation, use on small-bore pipeline.
Claims (1)
- A kind of manual online measuring pressure wafer type butterfly valve, include body, this body has manual overvide, mandrel, compositions such as wafer type valve body is characterized in that: prime seal ring and final-stage seal circle mechanical connection in the sealing pair interlayer that increases on the butterfly plate, adapter, online detection sealing load pipe mechanical connection in the wafer type valve body, mandrel and butterfly plate mechanical connection, manual overvide and mandrel mechanical connection, manual overvide and wafer type valve body mechanical connection.
