Abstract
The utility model provides a cage type single-seat control valve which comprises a valve body, a valve cover, a sleeve, a main valve core and a pilot valve core. The valve cover is fixed on the upper end face of the valve body, the sleeve is arranged in an inner cavity of the valve body, the main valve core is arranged on the inner surface of the sleeve and can slide along the inner surfaces of the sleeves, a pilot valve core valve seat is arranged on the main valve core, and the pilot valve core is arranged above the pilot valve core valve seat. The cage type single-seat control valve can solve the problem that in the prior art, driving force is large when a valve door is opened or closed.
Description
Technical field
The utility model relates to valve field, relates in particular to a kind of cage type single seat regulating valve.
Background technique
In industrial production, along with improving constantly of automation, modulating valve more and more has been applied to industry-by-industry as the terminal original paper in the process control.Cage type single seat regulating valve mainly uses as the emptying cut-off valve as the terminal original paper in the process control, and especially high temperature, high pressure and heavy caliber require the occasion, particularly trim of cut-out easily to rotate the damage occasion.At present, driving force is big during the cage type single seat regulating valve switch valve, and valve akinesia or phenomenon slow in one's movements take place sometimes.
The model utility content
In view of this, the utility model provides a kind of cage type single seat regulating valve.Can solve existing in the big problem of driving force during switch valve.
A kind of cage type single seat regulating valve that the utility model provides, comprise: valve body, valve gap, sleeve, main valve plug and guide's spool, described valve gap is fixed on described valve body upper-end surface, described body cavity is provided with sleeve, described main valve plug is arranged on can be along described sleeve interior surface slip guide spool on the internal surface of described sleeve, described main valve plug is provided with guide's spool valve seat, and described guide's spool is arranged on described guide's spool valve seat top.
Further, also comprise: be arranged on the elastic member that is used for the described guide's spool of control and main valve plug axial vibration trend between described guide's spool and the main valve plug.
Further, also comprise: platen, described platen is fixed on the upper-end surface of described main valve plug, and the part of described guide's spool is pressed in the described main valve plug.
Further, screw for anti-rotation is housed between described platen and the guide's spool.
Further, the joint between described guide's spool and the bonnet is provided with rotation prevention structure.
Further, described rotation prevention structure is the anti-pivoted housing that is welded on the described bonnet.
The beneficial effects of the utility model:
Cage type single seat regulating valve of the present utility model compared with the existing, have two spools, be main valve plug and guide's spool, thereby make it that two openable sealing positions be arranged, one is the sealing position that sleeve and main valve plug are formed, one is the sealing position that guide's spool valve seat and guide's spool are formed, and then makes that the sealing driving force tight more, switch valve of cage type single seat regulating valve of the present utility model is littler.
Further, (for example: spring), thereby control in the axial direction vibration trend between the two makes it than existing valve operation balance to the utility model by elastic member formerly is set between guide valve core and the main valve plug.
Further, the utility model arranges the screw of anti-rotation between platen and guide's spool, and formerly between guide valve core and the bonnet rotation prevention structure is set, and all can avoid when trim is subjected to unbalanced force, cause that valve rod is stuck, the situation of distortion, fracture takes place.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the embodiment's of the cage type single seat regulating valve that provides of the utility model structural representation.
Fig. 2 is the embodiment's of the A part among Fig. 1 structural representation.
Fig. 3 is the embodiment's of the B part among Fig. 1 structural representation.
Embodiment
As illustrated in fig. 1 and 2, the cage type single seat regulating valve that provides of the utility model comprises: valve body 1 and valve gap 2.Wherein valve gap 2 is fixed by the upper-end surface of hexagon head bolt and valve body 1.Valve body 1 inner chamber is provided with the fluid passage of S shape.And the inner chamber at valve body 1 is provided with sleeve 3, in the inside of sleeve 3 main valve plug 4 is set.Main valve plug 4 is installed on the internal surface of sleeve 3, and can slide up and down along the internal surface of sleeve 3, when main valve plug 4 along the internal surface of sleeve 3 during to lower slider, it can seal sleeve 3, thus the flowing of blocking-up S shape runner inner fluid.
Characteristics of the present utility model are, main valve plug 4 is provided with guide's spool valve seat 5, and this pilot valve valve seat 5 comes down to an aperture that radially connects on the main valve plug 4.Formerly the top of guide valve core valve seat 5 is provided with guide's spool 6, and guide's spool 6 can seal this guide's spool valve seat 5.By this kind structure, in a modulating valve, realized double spool, than existing single spool structure, have better sealing effect, littler switch valve driving force.
Further, the part of guide's spool 6 is pressed on the main valve plug 4 by platen 9.Particularly, formerly has outside projection on the guide valve core 6, platen 9 is fixed on the upper-end surface of main valve plug 4 by hexagon head bolt 8, and with the projection of guide's spool 6, and the bottom of projection is pressed in the main valve plug 4, the projection of guide's spool 6 is passed platen 9 with the upper part, and is connected with valve rod 12 by pin, and valve rod 12 passes bonnet 2 and is connected with the clutch end of actuator.Between platen 9 and the guide's spool 6 screw 10 is installed also, rotates to prevent pilot valve core 6.More specifically, formerly also be provided with elastic member between guide valve core 6 and the main valve plug 4, spring for example, its effect is the vibration trend of the above-below direction of control guide's spool 6 and main valve plug 4.
As shown in figs. 1 and 3, the joint between guide's spool 6 and the bonnet 2 also is provided with rotation prevention structure, to avoid guide's spool 6 because button changes being subjected to force unbalance, causes situation generations such as valve stem crack.Particularly, rotation prevention structure can be the anti-pivoted housing 11 in bonnet 2 welding.Cooperation place between guide's spool 6 and the anti-pivoted housing 11 is deltiod, namely forms square rotation prevention structure.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
