Description
Technical field
The present invention relates to valve field, specifically refer to a kind of Multifunctional combined valve with cut-out and non-return.
Background technique
Power in Cemented filling or plant running all derives from pump, generally all will be installed in series after pump a safety check and a cut-off valve, two deck valve doors are installed and just higher requirement are proposed to installing space, also will be higher to installation specification, and directly affects the installation of valve site and normally to use.
Summary of the invention
The object of the invention is the shortcoming and defect existed to overcome prior art, and provide one to have cut-out and automatic braking function, and do not change the Multifunctional combined valve of ball valve normal structure length.
For achieving the above object, the technological scheme of this valve includes valve body, valve component, valve gap and spheroid assembly, the valve rod that this spheroid assembly includes spheroid and is linked with spheroid, described valve component includes spheroid valve seat, described valve body is provided with valve flowing channel and is positioned at the valve pocket on valve flowing channel, described sphere installation is in valve pocket, this spheroid is provided with spheroid runner, on valve body opposing spheres side valve flowing channel in be provided with check valve spool assembly, this mangetic core assembly includes non-return valve block, described valve flowing channel is provided with the Boilor check valve seat that be sealed and matched corresponding to non-return valve block.
By this setting, under the prerequisite not changing ball valve normal structure length, be provided with corresponding check valve spool assembly in valve flowing channel, make it have cut-out and automatic braking function, and overall space arranges compact, installation footprint is little simultaneously.
Further setting is described check valve spool assembly is Bivalved check valve mangetic core assembly, this Bivalved check valve mangetic core assembly includes positioning plate, valve shaft and reduction torsion spring, described positioning plate is fixedly installed in valve flowing channel, valve shaft is arranged on positioning plate, described non-return valve block includes two panels flap, this two panels flap relative symmetry and all connecting with valve shaft, the two is that rotary opening and closing action is done in axle center with valve shaft, described reduction torsion spring cover is arranged on valve shaft, and two presser feets of reduction torsion spring are positioned on two flaps of both sides respectively.By this setting, provide a kind of Bivalved check valve mangetic core assembly structure being suitable for valve flowing channel and installing, organization establishes is convenient, good stability.
This arranges described check valve spool assembly can also be butterfly shaped check valve mangetic core assembly or Swing check valve mangetic core assembly.
Further setting is described spheroid valve seat is single valve seat, be installed on the valve interior wall of spheroid side, described spheroid opposing spheres runner side outer wall projection is provided with ring packing sphere, this ring packing sphere and the same centre of sphere of spheroid, and this ring packing sphere and spheroid valve seat are in closed condition lower seal at ball valve is equipped with, described spheroid assembly also includes lower rotary shaft, described valve rod and lower rotary shaft are arranged at the upper and lower two ends of spheroid respectively, and described valve rod and lower rotary shaft are coaxially arranged, described ring packing sphere and the centre of sphere of spheroid be not on the axis of valve rod and lower rotary shaft, form eccentric setting.
By this setting, when opening valve, valve rod is rotated counterclockwise and drives spheroid to depart from spheroid valve seat instantaneously, in whole valve opening process with spheroid sealing surface of seat without any contacting, after valve wide open, spheroid runner is communicated with completely with valve flowing channel, and along with valve aperture increase gap larger, when opening valve completely, ring packing sphere and the spheroid sealing surface of seat of spheroid have gap, but spheroid still can block whole spheroid sealing surface of seat, prevent that spheroid valve seat from exposing completely and by medium erosion failure, in valve opening and closing process, moment of torsion is very low;
During throttle down, after rotation valve rod, the ring packing sphere of spheroid gradually near spheroid valve seat until close completely.
At present, in traditional upper-mounting type ball valve, the overwhelming majority is double-valve-seat structure, and spheroid is tightly embraced in centre by two valve seats, close contact all the time in switching process, and large, the online dismounting of moment of torsion is very difficult; And wherein small part upper-mounting type ball valve is single valve seat ball valve, its spheroid arranged is hemisphere or scarce ball, and after valve open, valve seat exposes completely, and very easily by medium erosion failure.Therefore, adopt technique scheme, the present invention can dismantle internals and on-line maintenance maintenance online, and does not wash away by medium, has low moment of torsion, frictionless advantage.
By this setting, when dismantling internals, whole spheroid assembly is by integral demounting, and convenient disassembly, and this setting, the installation of spheroid assembly is also more convenient.
Further setting is that described lower rotary shaft includes the axial sphere being positioned at its avris portion and the bottom sphere be positioned at bottom it.By this setting, when dismantling internals, the lower rotary shaft due to spheroid assembly is the setting of two spheres (axle center sphere and bottom sphere), as long as so tilted slightly by spheroid assembly can depart from spheroid sealing surface of seat completely, dismantle very convenient.
Further setting is that described valve component also includes valve seat insert, trim ring, trim ring Returnning spring and sand prevention ring, or described valve component includes the gasket seal be arranged at inside spheroid valve seat.
Further setting is that described spheroid valve seat adopts the screw thread axis hole on spiral way and valve interior wall to form detachable screw thread secure fit.By this setting, not only facilitate the installation of spheroid valve seat, and spheroid valve seat convenient disassembly.
Further setting is that the bottom of spheroid valve seat is provided with dismounting groove.This setting, the convenient adjustment to spheroid seating position and dismounting.
In sum, the present invention has compact structure, has cut-out and automatic braking function, and do not change ball valve normal structure length, but also have and can dismantle internals, on-line maintenance maintenance online, do not wash away by medium, the advantage such as low moment of torsion, nothing friction in switching process.
Below in conjunction with specification drawings and specific embodiments, the present invention is described further.
