Description

The hard sealing welding butterfly valve of double-shaft two-way
Technical field
The present invention relates to welding butterfly valve fields, the specifically hard sealing welding butterfly valve of double-shaft two-way.
Background technique
With the rapid development of world economy, nowadays, petroleum, combustion gas resource are nervous, energy shortage, and oil and natural gas Demand it is increasing, it has to turn to very poor awful weather, topography and geomorphology, unfrequented severe winter, desert, marsh and sea The new energy place of production such as foreign continental shelf, this has caused great difficulties to transfer oil, natural gas.Pipeline conveying is natural gas The major way of transport, according to statistics, 95% or more the conveying of natural gas uses pipelined fashion in the world, and uses the big mouth of single Diameter, elevated pressures mode of movement reduce investment, maintenance cost.
In the fast development of national economy, pipeline transportation is made at petroleum, the important transportation approach of combustion gas, heating Valve for pipe control function plays an important role, and in the pipe-line system of the industries such as the energy, metallurgy, petrochemical industry, needs Various valves fill the functions such as pressure to realize cut-off, adjusting, pressure stabilizing, shunting or overflow, and valve can be used for controlling empty gas and water, various The flowing of the various types fluid such as corrosive media, mud, oil product, liquid metal and radiating medium, moreover it can be used to solid The pipeline transportation of matter.
In the different various valves of purposes, butterfly valve is good with its cut-out performance, and leakage is few, and regulation performance is good, high Fast flux, good corrosion resistance, size are small, weight is low, are easy to the advantages that configuring, and application range is constantly expanded, in addition to most Outside the suitable environment of first room temperature, low pressure and general medium, in the chemical industry of seriously corroded, butterfly valve comes from application effect Consideration can almost substitute over common shut-off valve, plug valve and ball valve etc..In fact, in modern urban construction engineering In, since the requirement to environmental protection is continuously improved, past usually used low pressure irony gate valve has been increasingly turned to environment-friendly type Metallic seal butterfly valve etc..
When in use, its butterfly plate must the positive stream for facing fluid media (medium) for unidirectional densification sealing butterfly valve currently on the market To in the pipeline of unidirectional densification sealing butterfly valve, fluid media (medium) can only be flowed to a direction, therefore have media flow on valve body The arrow in direction, especially it is noted that being installed according to arrow direction when the installation of unidirectional densification sealing butterfly valve.In order to widen butterfly valve The scope of application, preferably than unidirectional densification sealing butterfly valve bi-direction consolidation sealing butterfly valve, it, which can be adapted for pipe ends, can have The case where media flow.
Bi-direction consolidation sealing butterfly valve when in use without the concern for butterfly valve fluid media (medium) flowing direction, but use when It waits, the pressure due to valve rod by medium in both direction, in design, the valve rod of bi-direction consolidation sealing butterfly valve is in diameter On be often greater than unidirectional densification sealing butterfly valve, but increase the diameter of valve rod and will cause after by surging when in use, valve rod It can cause to wear because of sliding friction between the bottom cover that is attached thereto, after abrasion, will appear between valve rod and bottom cover Gap, when fluid media (medium) generated on butterfly plate pressure it is excessive when, valve rod is lifted up in stem shaft or falls downward, be easy Stem shaft is caused because of torsion excessive the phenomenon that causing bending shaft, in addition also results in bi-direction consolidation sealing butterfly valve poor sealing.
