Abstract
The utility model relates to a multi-turn valve with a bracket connected through a screw thread, which comprises a valve body, a valve cover, a valve rod, a valve rod nut and the bracket. The valve rod nut is axially fixedly arranged in an inner hole at the upper part of the bracket. Gland packing is arranged between the valve cover and the valve rod by a packing gland. The lower part of the bracket is arranged on the valve cover through the screw thread. Mainly, a plurality of round concave holes are formed in an upper plane of the packing gland, the bracket above the round concave holes is provided with corresponding screw holes, bolts are respectively arranged in the screw holes, and the lower end parts of the bolts are pressed against the inside of the round concave holes in the upper plane of the packing gland. A vertical slot is arranged at the lower part of the bracket at a position where the screw thread is arranged. Both sides of the vertical slot are respectively provided with convex lugs. The convex lugs are provided with mounting holes. The multi-turn valve has the advantages that the bracket is reliably locked and fixed; a packing pressing force is stable; the sealing performance between the valve rod and the valve cover is reliable; the multi-turn valve is convenient to assemble, disassemble and maintain, and the like. The multi-turn valve is suitable for various multi-turn valve structures such as a stop valve, a gate valve, etc.
Description
Technical field
The utility model relates to valve field, specifically about a kind of holder connection device of many turning valves.
Background technique
Many turning valves generally comprise valve body, valve gap, flap, valve rod, handwheel and support; Handwheel is fixedly mounted on the Stem Mut; In the rack-mount end endoporus of Stem Mut; Support lower end and valve gap are integrally casting or forging molding or are connected through bolt that the shortcoming of integral type Placement is a dismounting maintenance trouble, and the shortcoming of bolt Placement is the situation that stripped thread and fracture appear in bolt fatigue after using certain hour.And common being threaded is employed in basically on the screw-thread fit face and bores two stopping rivets and be locked, and its shortcoming is that the stopping rivet is stressed little, and locking effect is poor, the dismounting trouble.And the patent No. is 200620091485.0 the self-pressure-sealed structure of valve rack formula; Appliance stand above valve gap; The support endoporus is overlapping Stem Mut and valve rod from top to bottom; With being threaded, support is supported on the valve body through lock washer between mid-stent and the valve gap, and filler is compressed by Gland and is installed between valve gap and the valve rod.Its major defect is: the support weak effect that is locked; Gland by the tension of bolt, nut be installed in two of support very heavy on; Tightening force is prone to make very heavy distortion, and after the tension screw thread between support and the valve gap is being produced bigger pulling force, easily damaged screw; Gland is reduced the impacting force of filler, influence the sealability between valve rod and the valve gap.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, and a kind of dismounting, easy to maintenance is provided, and it is reliable to be locked, many turning valves that the support of the good seal performance between valve rod and the valve gap is threaded.
The technological scheme of the utility model comprises valve body, valve gap, valve rod, Stem Mut, support, and Stem Mut is axially installed in the endoporus of support top, by Gland stuffing box packing is installed between valve gap and the valve rod.Mainly be that the support bottom is installed on the valve gap by screw thread, support lower thread place is shaped on vertical slot, and said vertical slot both sides are respectively equipped with lug, are shaped on mounting hole on the lug, in this mounting hole, clamping bolt are installed.On Gland, be shaped on several circular shrinkage hole in the plane, on the support above the said circular shrinkage hole, be shaped on corresponding screw, construction bolt respectively in said screw, top, bolt underpart is contained on the Gland in the circular shrinkage hole in the plane.
The utility model has the advantages that support is installed on the valve gap by screw thread and clamping bolt; Gland holds out against filler by bolt downwards from support, its support is locked reliably, and the filler impacting force is stable; Sealability is reliable between valve rod and the valve gap, dismounting, easy to maintenance.
