Description
Technical field
The utility model relates to a kind of upper-mounting type ball valve, and particularly the interior mode integrated ball valve of dress on a kind of high temperature, be applicable to the oil and natural gas pipeline, and in the devices such as oil recovery, oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgy, electric power, nuclear power, food and papermaking.
Background technique
Since China's reform and opening-up, the national economy rapid growth, " scientific and technical innovation, autonomous innovation " become the main flow of domestic industry development.China's industry is just step by step to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).Ball valve has compact structure as a kind of common valve, and is lightweight, and fluid resistance runs off less and the advantage such as maintenance operation is convenient, therefore uses very extensive.On the flowing medium pipelines such as oil, petrochemical industry, the long-time parking of some process pipelines is unallowed, and there is the shortcoming of detachable maintaining difficulty in the employing common valve, so the available technology adopting upper-mounting type ball valve replaces conventional valves.Its valve body of upper-mounting type ball valve is integrated type, and spheroid is packed into from the top of valve body, opens valve gap and can take out internal components, and dismounting is rapidly simple, and is easy to maintenance quick.Mainly there is following defective in existing upper-mounting type ball valve: the first, ball valve in use, because spheroid and seal ring produce friction, because of wearing and tearing, there is no enough pretightening forces after the long-time use of valve, seal ring can not get mending to be tasted, be easy to produce internal leakage, impact is used, and even scraps; The second, it is complicated that the major-minor body connects manufacturing process, and cost is high, and sealing that should the place is fully by the bolt compress gasket, and when pipe vibration or medium temperature, pressure change, screw bolt and nut can become flexible, pad is aging in addition, and medium is easy to from here to external leakage; The 3rd, because of single face sealing, seal pressure is large, and the valve operation moment of torsion increases thereupon, and middle head valve bar filler place is not owing to there is no the spring designing load, with long afterwards easily generation leak outside.The technician of R﹠D institution and enterprise is constantly exploring, is studying, and wishes to develop a kind of ball valve of superior performance, although make some progress, still exists the technical barrier that not yet overcomes in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and mode integrated ball valve in dress is provided on a kind of high temperature, and spheroid is connected with valve rod, pack into from the valve body lumen, and employing butterfly spring designing load, good sealing effect, lightweight, save material.
the technological scheme that its technical problem that solves the utility model adopts is: contain valve body, butterfly spring I, valve seat, spheroid, valve gap, hex head bolt, filler, butterfly spring II, Gland, valve rod, handle, the runner of valve body is cylindrical shape, its middle part is cavity, the top is fixedly connected with valve gap, be connected by hex head bolt between valve body and valve gap, valve body central authorities are provided with valve rod, valve rod passes valve gap and is connected with handle, spheroid is housed in valve body, spheroid top and valve rod are integrated connections, the spheroid both sides respectively are provided with the seal ring that is sealed and matched with it, valve seat is symmetricly set on spheroid both sides, valve seat, seal ring is packed into from valve body two ends passage, valve seat, the shoulder place of seal ring is provided with butterfly spring I, filling container is positioned at the periphery of valve rod, filler is contained in filling container, butterfly spring II compresses filler, butterfly spring II top is provided with Gland, Gland is connected with valve gap.
The know-why that its technical problem that solves the utility model adopts is: ball valve is mainly for open and close pipeline and equipment medium, to use with the spheroid of circular channel to do open-shut device, by handle with sleeve, spheroid rotates 90 ° with valve rod, realizes the keying of valve.The open-shut device of ball valve is a porose spheroid, and this spheroid rotates around the axis perpendicular to passage, thereby reaches the purpose that opens and closes passage.Adopt the integrated type valve body to solve the outside leakage problem in major and minor body pad place in the past.Valve seat, seal ring are packed into from valve body two ends passage, and the two ends high-temperature-resistant flexible graphite packing seal ring of packing into is in case valves leakage.Shoulder place at valve seat insert is provided with butterfly spring I, and the pretightening force at its two ends is tasted because butterfly spring I can mend voluntarily by adjusting nut compressing butterfly spring I, and the thrust that it produces can the permanent radial seal that realizes valve seat and spheroid.Middle flange seal adopts resistant to elevated temperatures 304 folder flexible graphite gaskets to realize.The high-temperature-resistant flexible graphite packing is also adopted in the sealing of valve rod place, compresses with Gland, and butterfly spring II loads, and can taste by automatic makeup after the filler wearing and tearing, guarantees that sealing herein is reliable, permanent.
The beneficial effects of the utility model are: spheroid is connected with valve rod, reduces the leak point.The high-temperature-resistant flexible graphite packing of circumferentially packing into of valve seat place and valve rod, and adopt butterfly spring designing load, good sealing effect.Valve body adopts integrated design, and is easy to maintenance, and technique is advanced, bears pressure high, serviceability temperature high (≤400 ℃), and using scope is wide.
