Background technique
Since China's reform and opening-up, national economy increases fast, scientific and technical innovation, and autonomous innovation has 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).Upper dress formula fixing ball valve is widely used on oil and natural gas pipeline, and in the device such as oil recovery, oil refining, petrochemical industry, chemical industry, chemical fibre, metallurgy, electric power, nuclear power, food and papermaking.Upper-mounting type ball valve is dismantled rapidly simple on pipeline, fast easy to maintenance.When valve break down on pipeline need to repair time, need not dismantle valve from pipeline, need only dismantle middle flange bolt and nut, take off valve gap together with valve rod group component from valve body, then takes out spheroid and valve seat combination part.Spheroid and valve seat can be repaired online, save time, reduce loss.Upper dress formula fixing ball valve generally adopts screw to back down valve seat or unclamps valve seat with adjusting nut, and spheroid is put into, then screws adjusting nut holddown spring and reach sealing, during assembling, amount of spring compression is large, assembling difficulty, seal pressure is large, and valve operation moment of torsion increases thereupon.The technician of R&D institution and enterprise is constantly exploring, is studying, and wishes the ball valve developing a kind of superior performance, although make some progress, still there is the technical barrier not yet overcome in practice.
Summary of the invention
The object of the invention is to overcome above deficiency, a kind of air pressure is provided to push the upper dress formula fixing ball valve of valve seat open, utilize low pressure gas to form piston effect by inlet hole and promote valve seat backward, spheroid is loaded, this project organization is simple, easy to install, save on-line maintenance, installation time, reduce labor intensity.
The technical solution adopted for the present invention to solve the technical problems is: containing valve body, spring, spring pressuring ring, spring seat fire-protection ring, O type circle, valve seat, plug screw, gland nut, valve seat insert, spheroid, stationary axle, valve gap, valve rod, land, turbine box, gland nut, action pressure-testing joint, seal washer, the runner of valve body is cylindrical shape, is cavity in the middle part of it, valve gap is bolted on valve body, and valve gap is provided with land, and land is provided with turbine box, valve body central authorities are provided with valve rod, and valve rod is connected with turbine box through valve gap, and valve body is built with spheroid, spheroid top is connected with valve rod, in the valve body at spheroid two ends, be respectively equipped with valve seat, on valve seat, cover has valve seat insert, is provided with spring between valve seat and valve body, body base is provided with the stationary axle coordinated with spheroid, by spring, spring pressuring ring, spring seat fire-protection ring, O type circle, valve seat is respectively charged into valve body, then gland nut is loaded valve body and screws, during assembling, seal washer, action pressure-testing joint, gland nut is contained on valve body respectively, after having assembled, respectively gland nut, action pressure-testing joint, seal washer is removed, and loads onto plug screw.
The present invention solves the know-why that its technical problem adopts: ball valve is mainly for open and close pipeline and equipment medium, and be do open-shut device with the spheroid with circular channel, 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, thus reaches the object opening and closing passage.During assembling, seal washer, action pressure-testing joint, gland nut are contained in respectively after on valve body, at air inlet pressurization (0.6MPa ~ 0.8MPa), valve seat is passed backward, from valve body lumen, spheroid is loaded, then the pressure of venting suction port, valve seat is made to lean on the active force return of spring, valve seat insert and spheroid are combined closely and are reached the effect of pre-tightening seal, have assembled rear respectively gland nut, action pressure-testing joint, seal washer dismounting, have loaded onto plug screw.
The invention has the beneficial effects as follows: utilize low pressure gas to form piston effect by inlet hole and promote valve seat backward, spheroid is loaded, and this project organization is simple, easy to install, saves on-line maintenance, installation time, reduces labor intensity.
