Abstract
The utility model provides an actuating mechanism anti-rotation structure for a regulating valve which comprises the following components: the actuating mechanism, an opening/closing nut, a bracket which is used for connecting the actuating mechanism with the valve body, a push rod which extends out of the actuating mechanism, and a valve rod which opens/closes the valve core. One end of the opening/closing nut connects the valve rod and the push rod together for performing action. The actuating mechanism anti-rotation structure for the regulating valve is characterized in that: one end of the opening/closing valve is provided with a bayonet; the bayonet is matched with a boss which is equipped on the bracket. The actuating mechanism anti-rotation structure for the regulating valve has the following beneficial effects: preventing rotation of the valve rod and the push rod, and ensuring normal operation of the actuating mechanism and the valve. Simultaneously the actuating mechanism anti-rotation structure for the regulating valve has the following advantages: simple and compact structure, attractive appearance, and high convenience in mounting/detachment.
Description
Technical field
The utility model belongs to a kind of valve body structure, relates to concretely a kind of actuator's anti-rotation structure of the modulating valve in industrial application.
Technical background
For heavy caliber modulating valve cage sleeve valve particularly, higher at rate of flow of fluid, when pressure reduction is larger, valve plug is easy to be with ovable valve stem to rotate together under the active force of fluid, if this moment is the traditional half nuts of adapted (do not have rotation inhibiting function) still, the push rod of actuator also will rotate with valve rod so, loses efficacy (actuator's damage) thereby cause positioning work piece to be controlled, and finally causes modulating valve not work.
The model utility content
The purpose of this utility model just is to provide a kind of actuator's anti-rotation structure of modulating valve, and the push rod that solves actuator in prior art rotates with valve rod, loses efficacy, damages thereby lead actuating mechanism controls, finally causes the inoperable problem of modulating valve.
Actuator's anti-rotation structure of a kind of modulating valve of the present utility model, comprise actuator, half nuts, be used for connecting the support of actuator and valve body, stretch out the push rod of described actuator and the valve rod that spool is carried out switch, one end of described half nuts links together valve rod and push rod and moves, it is characterized in that: an end of described half nuts is provided with bayonet socket, and the boss that arranges on described bayonet socket and support matches.By valve rod end and half nuts being arranged keyway and being fixed on boss on support by half nuts, follow the problem of rotation with regard to having prevented valve rod and push rod.
Further, two end faces that described bayonet socket is arranged on that described half nuts fits and away from an end that connects valve rod and push rod, the described bayonet socket opening that the plane lower than two end faces that fit forms of serving as reasons.This is simple in structure, and is easy to make.
Further, be provided with keyway in the through hole of described half nuts connection push rod and valve rod, described valve rod end is provided with keyway.By keyway is set, push rod is fixed together by half nuts and valve rod, forms action together, carry out the instruction of actuator.
Further, be provided with a plurality of bolts hole on described half nuts.A plurality of bolts hole are set, and to be convenient to fastening the time each orientation stressed evenly.
Beneficial effect
The beneficial effects of the utility model are to improve by the structure of half nuts, prevent that valve rod and push rod from rotating, and have guaranteed the normal operation of actuator, and this is simple and compact for structure simultaneously, exquisite appearance, easy installation and removal.
Description of drawings
Shown in Figure 1 is structural representation of the present utility model,
Fig. 2 is the B-B sectional view of Fig. 1.
Embodiment
As shown in Figure 1, 2, actuator's anti-rotation structure of a kind of modulating valve of the present utility model, comprise actuator, half nuts 3, be used for connecting the support 2 of actuator and valve body, stretch out the push rod 1 of described actuator and the valve rod 6 that spool is carried out switch, one end of described half nuts 3 links together valve rod 6 and push rod 1 and moves, two end faces that described half nuts 3 fits and the plane lower than faying surface is set away from an end that connects valve rod and push rod, form opening 7, on described opening 7 and support 2, the boss of setting matches.Be provided with keyway and be arranged on the interior flat key 4 of keyway in the through hole of described half nuts connection push rod 1 and valve rod 6, described valve rod end is provided with keyway.Be provided with a plurality of bolts hole on described half nuts, by bolt 5, that half nuts is fastening, be used for clamping gripped object.
Operating process: when half nuts is installed, with half nuts half keyway and the keyway position alignment on valve rod, also to guarantee simultaneously the position consistency of the boss of the opening of half nuts and support, again second half of half nuts closed up valve rod and valve rod are clamped in the lump, with hex head bolt, two half-sums of half nuts are tightened at last together.
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 modify 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 claim scope of the present utility model.
