Description
Technical field
The utility model relates to valve field, specifically refers to a kind of Multifunctional combined valve that can dismantle online.
Background technique
At pipeline, carry or install operating power and all derive from pump, a safety check and a cut-off valve generally all will be installed after pump, the installation requirement of two deck valve doors has larger space, this just has higher requirement to the performance of valve and maintenance, to installation specification, also will be higher, 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 soldered connect etc., when safeguarding to valve, generally all need whole deck valve door dismounting, very difficult from pipeline or device dismounting valve, particularly the general employing of high pressure valve is weldering Placement, and the soldered current main method that adopts flame to cut of valve that connects could be dismantled, very difficult and danger close.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, can dismantle online and safeguard, and have and cut off and automatic braking is multi-functional can dismantle online Multifunctional combined valve and provide a kind of.
For achieving the above object, the technical solution of the utility model 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 spheroid valve seat, on described valve body, be provided with valve flowing channel and be positioned at the valve pocket on valve flowing channel, described sphere installation is in valve pocket, on this spheroid, be provided with spheroid runner, described spheroid valve seat is single valve seat, be installed on the valve interior wall of spheroid one side, the relative spheroid runner one side outer wall projection of described spheroid 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 equipped with in closed condition lower seal at ball valve, described spheroid assembly also includes lower rotary shaft, described valve rod and lower rotary shaft are arranged at respectively the upper and lower two ends of spheroid, and described valve rod and lower rotary shaft coaxially arrange, 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, on valve body, relatively in the valve flowing channel of spheroid one side, be provided with axial flow type check valve mangetic core assembly, this axial flow type check valve mangetic core assembly includes guide rod, guide rod slippage cover, non-return valve block, reset cylindrical spring and valve pocket, described guide rod is fixedly installed in fluid valve road, described non-return valve block interlock is arranged at guide rod slippage and puts, this guide rod slippage cover slippage is arranged on guide rod, described valve pocket is fixedly installed on the inner of guide rod, described reset cylindricality spring housing is located on guide rod, and the two ends of this reset cylindrical spring respectively with valve pocket and non-return valve block effect butt, on described valve flowing channel, be provided with the Boilor check valve seat that be sealed and matched corresponding to non-return valve block.
By this setting, do not changing under the prerequisite of ball valve normal structure length, in valve flowing channel, be provided with corresponding check valve spool assembly, it is had simultaneously and cut off and automatic braking function, and overall space arranges compactness, installation footprint is little.
In addition, this setting, while opening valve, valve rod is rotated counterclockwise and drives spheroid moment disengaging spheroid valve seat, whole open valve process in 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 the aperture increase gap of valve is 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 spheroid valve seat from exposing completely and washed away damage by medium, 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, the spheroid of its setting is hemisphere or scarce ball, and after valve open, valve seat exposes completely, and very easily by medium, is washed away damage.Therefore, adopt technique scheme, the utility model can be dismantled 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 also this arranges, and the installation of spheroid assembly is also more convenient.
Further arrange is that described lower rotary shaft includes the bottom sphere that is positioned at the axial sphere of its avris portion and is positioned at its bottom.By this setting, in dismounting during 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 spheroid assembly is tilted to depart from spheroid sealing surface of seat completely 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, or described valve component includes the gasket seal that is arranged at spheroid valve seat inner side.
Further arrange 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.
The bottom that further setting is spheroid valve seat is provided with dismounting groove.This setting, convenient adjustment and the dismounting that ball valve seat is put.
In sum, the utility model has the advantages that: the utlity model has compact structure, have and cut off and automatic braking function, and do not change ball valve normal structure length, but also have, can dismantle online the maintenance of internals, on-line maintenance, be not subject to that medium washes away, low moment of torsion in switching process, without advantages such as frictions.
