Abstract
The utility model provides a double-piece type pressing sleeve structure, which comprises a valve body, a valve rod and a pressing plate which are coaxial in the center, wherein the pressing plate is positioned above the valve body and is fixedly connected with the valve body; the pressing sleeve is held down by the pressing plate; a filler box is held down by the pressing sleeve; the valve body is held down by the bottom of the filler box; the valve rod penetrates through the pressing plate, the pressing sleeve, the filler box and the valve body from top to bottom in sequence; and the filler box is divided into a filler sealing layer and a filler pad from top to bottom. The double-piece type pressing sleeve structure is characterized in that: the pressing sleeve is divided into two pieces, i.e., a first pressing sleeve and a second pressing sleeve, respectively; and the first pressing sleeve and the second pressing sleeve are arranged adjacently. According to the double-piece type pressing sleeve structure, when pressure born by the pressing sleeve is overlarge, the second pressing piece has a buffer effect, so that the surface of the filler can be protected, the service life of the filler is prolonged, a long-term good sealing effect of the filler is guaranteed, the wear of the structure of the valve rod is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to mechanical equipment technical field, is specifically related to be used for the double-disk gland structure of packing seal place of valve.
Background technique
The valve packing sealing is to guarantee that the significant points of seepage does not take place in running valve; Mostly the structure of existing packing seal place is single gland structure as shown in Figure 1, and when gland was stressed, active force directly was pressed onto on the filler; Stressed when big when gland, filling surface is easy to wear.When valve rod rotated, the filler of damage entered between valve rod and filler easily, the long-time use wearing and tearing that can strengthen stem structure, the working life of shortening valve.
Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art, and it is a kind of simple in structure that the purpose of the utility model provides, the double-disk gland structure of packing seal place that is used for valve easy to assembly; Can protect filling surface; Prolong filler working life, reduce the wearing and tearing of stem structure, do not take place to leak guaranteeing; Guarantee long-time normal use of valve, increase the service life.
The technological scheme of the utility model is:
Double-disk gland structure; The pressing plate that comprises the coaxial valve body in center, valve rod and be positioned at said valve body top and be fixedly connected with said valve body, said pressing plate compresses gland downwards, and gland compresses Stuffing box downwards; The bottom of said Stuffing box compresses said valve body; Said valve rod passes said pressing plate, gland, Stuffing box and valve body from top to bottom successively, is packing seal layer and Packing seat in the said Stuffing box from top to bottom, and it is characterized in that: said gland has two; Be respectively first gland and second gland, said first gland and said second gland are in abutting connection with setting.
The double-disk gland structure of the utility model, when the pressure that bears when gland was big, second compressing tablet can play buffer function; Thereby can protect filling surface, prolong filler working life, guarantee filler good sealing effect for a long time; Reduce the wearing and tearing of stem structure, increase the service life.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Double-disk gland structure as shown in Figure 2; The pressing plate 3 that comprises the coaxial valve body in center 1, valve rod 2 and be positioned at the valve body top and be fixedly connected with valve body, pressing plate compresses gland 4 downwards, and gland compresses Stuffing box 5 downwards; The bottom of Stuffing box compresses valve body; Valve rod passes pressing plate, gland, Stuffing box and valve body from top to bottom successively, is packing seal layer 6 and Packing seat 7 in the Stuffing box from top to bottom, and gland has two; Be respectively the first gland 4-1 and the second gland 4-2, the first gland 4-1 and the second gland 4-2 are in abutting connection with setting.The utility model adopts double-disk gland structure as shown in the figure; When the pressure that bears when gland was big, second gland can play buffer function, thereby can protect filling surface; Prolong filler working life; Guarantee filler good sealing effect for a long time, reduce the wearing and tearing of stem structure, increase the service life.
Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think the protection domain that falls into the utility model.
