Abstract
The utility model provides a filling material pressing mechanism, which comprises a filling material box, a valve rod, a press sleeve, filling materials and a press plate, wherein the filling material box is in a center coaxial state, the valve rod passes through the center of the filling material box, the press sleeve is sheathed outside the valve rod, the filling materials are tightly pressed under the press sleeve and are positioned between the valve rod and the filling material box, and the press plate is sheathed outside the valve rod and is tightly pressed on the press sleeve. The filling material pressing mechanism is characterized in that the press plate is fixedly arranged on the filling material box. The filling material pressing mechanism provided by the utility model has the advantages that the press plate is directly and fixedly connected with the filling material box, the thrust is provided for tightly pressing the filling materials, and the leakage caused by poor sealing performance due to gaps generated among the filling materials after the long-time use of the filling materials can be avoided.
Description
Technical field
The utility model relates to mechanical equipment technical field, is specifically related to a kind of filler hold-down mechanism.
Background technique
The packing seal of valve is as shown in Figure 1 to guarantee that the significant points of seepage does not occur valve in running, but after valve is used for a long time, between filler, easily produce gap, cause sealability bad and produce to reveal, so existing structure as shown in Figure 1, pressing plate and gland upper and lower sleeve are located at outside valve rod, pressing plate compresses filler by gland, double-screw bolt is passed down through the pressing plate stepping of going forward side by side and enters Stuffing box, and by nut, pressing plate is fixedly connected with Stuffing box, thereby filler is pressed in Stuffing box, need in use for some time fastening nut to seal completely to guarantee filler, also there is existing structure processing trouble and complicated problem is installed.
Summary of the invention
The utility model completes in order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of simple in structure, the filler hold-down mechanism of valve easy to assembly, reach by carry out the object of compressible filler from pretightening force, do not occur to leak guaranteeing, long-time normal use that guarantees valve, increases the service life.
The technical solution of the utility model is:
A kind of filler hold-down mechanism, comprise the coaxial Stuffing box in center, through the valve rod at the center of described Stuffing box, be set in gland outside described valve rod, be pressed on the filler under described gland and between described valve rod and described Stuffing box and be set in outside described valve rod, be pressed on the pressing plate on described gland, it is characterized in that: described pressing plate is fixed on described Stuffing box.
Further, the technical solution of the utility model can also be:
Described pressing plate is by the surface plate of center drilling and from the lower surface of described surface plate, protrude the annular boss extending to form downwards and form; The center drilling of described surface plate is used for through described valve rod, described filler is pressed between the lower surface and described valve rod and described Stuffing box of described gland, and described pressing plate is fixedly connected with described Stuffing box screw thread by the screw thread on the annular outer wall of described boss; Described gland is between described valve rod outer wall and the inwall of described boss.
Filler hold-down mechanism of the present utility model, by pressing plate is directly fixedly connected with Stuffing box, provides thrust to compress filler, avoids filler between long rear filler, to produce gap and cause the bad generation of sealability to be revealed service time.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of filler hold-down mechanism as shown in Figure 2, comprise the coaxial Stuffing box in center 1, through the valve rod 2 at the center of Stuffing box, be set in gland 3 outside valve rod, by gland 3, compressed downwards and the filler 4 between valve rod and Stuffing box, and be set in valve rod outer, be pressed on the pressing plate 5 on gland, it is characterized in that: pressing plate is directly fixed on Stuffing box.
In this example, the structure of pressing plate as shown in Figure 2, by the surface plate 5.1 of center drilling with protrude from the lower surface of surface plate the annular boss 5.2 extending to form downwards and form; Valve rod passes center drilling, gland, the filler of surface plate from top to bottom, filler is pressed in gland lower surface, and between the outer wall and Stuffing box of valve rod, pressing plate is fixedly connected with Stuffing box screw thread by the screw thread (not shown) on the annular outer wall of boss, and gland is between valve rod outer wall and the inwall of boss.
The utility model utilizes valve rod from top to bottom successively through pressing plate, gland and filler, pressing plate compresses gland downwards, gland compresses filler downwards, pressing plate is directly fixedly connected with Stuffing box (valve gap) screw thread, thereby pressing plate compresses gland then filler is pressed in Stuffing box, to have reached hermetic object, and good sealing effect.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think and fall into protection domain of the present utility model.
