Compared with the prior art, the utility model discloses from in -band screw thread and valve gap cooperation assembly, convenient processing and assembly to use cost is low.
Description
Technical field
The utility model relates to a kind of pressing plate seat, is specifically related to a kind of wiper seal pressing plate seat.
Background technique
At present, existing wiper seal valve fixes the stud of hold-down grid is generally two schemes.Scheme 1: the microcephaly of valve gap beat tapped hole connect; Scheme 2: the big wheel of valve gap beat tapped hole connect.But along with the bore of valve, the increasing of pressure, the thickness of the filler selected by standard also continues to increase, and causes the larger of bore pressure, the little grease head highness of wiper seal valve gap is also more and more higher.If operational version 1 is punched the microcephaly of valve gap, so in order to ensure stuffing box and the intensity of tapped hole of beating, need the diameter increasing former valve gap microcephaly; If operational version 2 is punched at the major part of valve gap, because the height of valve gap microcephaly is higher, so selected stud is also long especially.Stud needs customization not easily purchase and not easily assemble.
Model utility content
The purpose of this utility model is to provide one to carry internal thread to coordinate with valve gap and assemble, convenient processing and assembling, and the wiper seal pressing plate seat that user cost is low.
For achieving the above object, the utility model provides following technological scheme:
A kind of wiper seal pressing plate seat, comprise valve gap, Packing seat, filler, pressing plate seat, filler pressing sleeve, hold-down grid, nut and stud, bonding pad in valve gap, filler top is hold-down grid, hold-down grid is provided with through hole, and valve gap is threaded connection pressing plate seat, and pressing plate seat is provided with attachment hole, connecting stud between through hole and attachment hole, stud top is provided with nut.
As the further improvement of above-mentioned technology, between described valve gap and filler, be provided with Packing seat.
As the further improvement of above-mentioned technology, between described filler top and hold-down grid, be provided with filler pressing sleeve.
As the further improvement of above-mentioned technology, described through hole and attachment hole are located on same vertical direction.
Compared with prior art, the beneficial effects of the utility model are: adopt pressing plate stand structure, convenient processing, easy assembling, by tapped hole connecting stud between pressing plate seat and hold-down grid, pressing plate seat is connected with valve gap small end top, then stud length can reduce, it is more convenient to use, tapped hole is located on hold-down grid, not be located on valve gap, then the small end wall thickness of valve gap only need meet standard, without the need to carrying out increasing process to valve gap small end diameter, adopt the mode replacing original tapping of punching on valve gap in the externally threaded mode of valve gap outer installment, reduce manufacture cost, by setting up the structure of pressing plate seat, because pressing plate stand structure is simply easily processed, cost also adds long threaded rod than original increase valve gap small end diameter or customization, and cost is low, and convenient processing and assembling, materials'use cost reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of pressing plate seat.
In figure: valve gap 1, Packing seat 2, filler 3, pressing plate seat 4, filler pressing sleeve 5, hold-down grid 6, nut 7, stud 8.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
A kind of wiper seal pressing plate seat, comprise valve gap 1, Packing seat 2, filler 3, pressing plate seat 4, filler pressing sleeve 5, hold-down grid 6, nut 7 and stud 8, bonding pad 3 in valve gap 1, Packing seat 2 is provided with between valve gap 1 and filler 3, Packing seat 2 plays protective action, filler 3 top is filler pressing sleeve 5, filler pressing sleeve 5 top bonding pad pressing plate 6, hold-down grid 6 is provided with through hole, valve gap 1 is threaded connection pressing plate seat 4, pressing plate seat 4, with on hold-down grid 6, the same vertical direction of through hole is being provided with attachment hole, connecting stud 8 between through hole and attachment hole, stud 8 is connected between pressing plate seat 4 and hold-down grid 6, length can be reduced, do not need the long threaded rod using customization, save cost of material, stud 8 top is provided with nut 7, nut 7 plays the effect be fastenedly connected.
During utility model works, valve gap 1 is provided with screw thread, and be threaded connection pressing plate seat 4, pressing plate seat 4 both sides are provided with attachment hole, connecting stud 8 between through hole on attachment hole and hold-down grid 6, on stud 8, cover has nut 7, by processing a screw thread in valve gap 1 end, valve gap 1 is coordinated with pressing plate seat 4, adopt pressing plate seat 4 structure, convenient processing, easy assembling, by tapped hole connecting stud 8 between pressing plate seat 4 and hold-down grid 6, pressing plate seat 4 is connected with valve gap 1 small end top, then stud 8 length can reduce, it is more convenient to use, tapped hole is located on hold-down grid 6, not be located on valve gap 1, then the small end wall thickness of valve gap 1 only need meet standard, without the need to carrying out increasing process to valve gap 1 small end diameter, the utility model adopts the mode replacing original tapping of punching on valve gap 1 in the externally threaded mode of valve gap 1 outer installment, reduce manufacture cost, by setting up the structure of pressing plate seat 4, because pressing plate seat 4 structure is simply easily processed, cost also adds long threaded rod than original increase valve gap 1 small end diameter or customization, and cost is low, and convenient processing and assembling, materials'use cost reduces.
The foregoing is only the utility model preferred embodiment; not thereby mode of execution of the present utility model and protection domain is limited; to those skilled in the art; the equivalent replacement that all utilization the utility model specifications and diagramatic content are made and the scheme that apparent change obtains should be recognized, all should be included in protection domain of the present utility model.
