Description
Technical field
The present invention relates to valve field, specifically refer to a kind of Multifunctional combined valve that can dismantle online.
Background technique
Carry or install operating power at pipeline and all derive from pump, a safety check and a cut-off valve generally all will be installed behind the pump, the installation requirement of two deck valve doors has larger space, this just has higher requirement to performance and the maintenance of valve, to be higher also to installation specification, directly affected installation and normal use of valve site.
On the other hand, the Placement of existing valve and pipeline or device is a lot, have that flange connects, is threaded, clip connected, folder connected and be connected connection etc., generally all need when safeguarding the dismounting of whole deck valve door doing to valve, very difficult from pipeline or device dismounting valve, particularly the general employing of high pressure valve is the weldering Placement, and weldering connects valve and mainly adopts at present the method for flame cutting could dismantle very difficult and danger close.
Summary of the invention
The objective of the invention is the shortcoming and defect that exists in order to overcome prior art, can dismantle online and safeguard and provide a kind of, and have and cut off and automatic braking is multi-functional can dismantle online Multifunctional combined valve.
For achieving the above object, technological scheme of the present invention is to include 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 the spheroid valve seat, be provided with valve flowing channel and the valve pocket that is positioned on the valve flowing channel on the described valve body, described sphere installation is in valve pocket, be provided with the spheroid runner on this spheroid, described spheroid valve seat is single valve seat, be installed on the valve interior wall of spheroid one side, projection is provided with the ring packing sphere on the relative spheroid runner one side outer wall of described spheroid, this ring packing sphere and the same centre of sphere of spheroid, and this ring packing sphere and spheroid valve seat are in the closed condition lower seal at ball valve and are equipped with, described spheroid assembly also includes lower rotary shaft, described valve rod and lower rotary shaft are arranged at respectively up and down two ends of spheroid, and the coaxial setting of described valve rod and lower rotary shaft, the centre of sphere of described ring packing sphere and spheroid is not on the axis of valve rod and lower rotary shaft, consist of eccentric setting, relatively be provided with the axial flow type check valve mangetic core assembly in the valve flowing channel of spheroid one side on the valve body, this axial flow mangetic core assembly includes guide rod, guide rod slippage cover, the non-return valve block, cylindrical spring and valve pocket reset, described guide rod is fixedly installed in the fluid valve road, described non-return valve block interlock is arranged at the guide rod slippage and puts, this guide rod slippage cover slippage is arranged on the guide rod, described valve pocket is fixedly installed on the inner of guide rod, the described cylindricality spring housing that resets is located on the guide rod, and the two ends of this cylindrical spring that resets respectively with valve pocket and non-return valve block effect butt, be provided with the Boilor check valve seat that be sealed and matched corresponding to the non-return valve block on the described valve flowing channel.
By this setting, under the prerequisite that does not change ball valve normal structure length, in valve flowing channel, be provided with corresponding check valve spool assembly, it is had simultaneously cut off and the automatic braking function, and overall space arranges compactness, installation footprint is little.
In addition, this setting, when opening valve, valve rod is rotated counterclockwise and drives spheroid moment disengaging spheroid valve seat, open in the valve process with the spheroid sealing surface of seat without any contacting whole, behind the valve wide open, the spheroid runner is communicated with fully with valve flowing channel, and along with the aperture increase gap of valve is larger, when opening valve fully, ring packing sphere and the spheroid sealing surface of seat of spheroid have the gap, but spheroid still can block whole spheroid sealing surface of seat, prevent that the spheroid valve seat from exposing fully and washed away damage by medium, moment of torsion is very low in the valve opening and closing process;
During throttle down, behind the rotation valve rod, the ring packing sphere of spheroid gradually near the spheroid valve seat until close fully.
At present, the overwhelming majority is the double-valve-seat structure in traditional upper-mounting type ball valve, and spheroid is tightly embraced in the 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 the small part upper-mounting type ball valve is the single valve seat ball valve, and the spheroid of its setting is hemisphere or scarce ball, and behind the valve open, valve seat exposes fully, and is very easily washed away damage by medium.Therefore, adopt technique scheme, the present invention can dismantle internals and on-line maintenance maintenance online, and not washed away by medium, has low moment of torsion, frictionless advantage.
In addition, this setting, in dismounting during internals, whole spheroid assembly is by integral demounting, convenient disassembly, and should arrange, the installation of spheroid assembly is also more convenient.
Further arrange is the bottom sphere that described lower rotary shaft includes the axial sphere that is positioned at its avris section and is positioned at its bottom.By this setting, when the dismounting internals, because the lower rotary shaft of spheroid assembly is the setting of two spheres (axle center sphere and bottom sphere), so as long as the spheroid assembly is tilted to break away from the spheroid sealing surface of seat fully slightly, dismantle very convenient.
Further arranging is that described valve component also includes valve seat insert, trim ring, trim ring Returnning spring and sand prevention ring, and perhaps described valve component includes the gasket seal that is arranged at spheroid valve seat inboard.
Further arrange is that described spheroid valve seat adopts the screw thread axis hole on spiral way and the valve interior wall to consist of detachable screw thread secure fit.By this setting, not only make things convenient for the installation of spheroid valve seat, and spheroid valve seat convenient disassembly.
The bottom that further setting is the spheroid valve seat is provided with the dismounting groove.This setting, convenient adjustment and the dismounting that the ball valve seat is put.
In sum, advantage of the present invention is: the present invention has compact structure, has and cut off and the automatic braking function, and do not change ball valve normal structure length, can dismantle online the maintenance of internals, on-line maintenance but also have, be not subjected to that medium washes away, low moment of torsion in the switching process, without advantages such as frictions.
