Abstract

The utility model discloses a self-compensating wear-resistant sealing strip, which comprises a strip-shaped body; the cross section of the strip-shaped body is T-shaped or square; a dovetail groove is formed on a sealing surface of the strip-shaped body; and a cylindrical hole or an elliptically cylindrical hole is formed in the center of the strip-shaped body. The utility model has the advantages of reasonable design, good sealing effect, self-compensating performance and long service life; and energy consumed for keeping high pressure or vacuum level can be greatly reduced.

Description

Self compensation wear-resistant seal bar
One. technical field: the utility model relates to a kind of Stamping Steel Ribbon, particularly relates to a kind of self compensation wear-resistant seal bar.
Two. background technique: industries such as flour, cement, grain are all used airlock usually at present, the post shell and the rotary blade of airlock are all cylinder iron made, when the blade on the impeller rotates at post shell inner chamber, material can enter at any time between the two the gap and make damage in impeller, causes the gap to increase, and airlock seriously leaks out, to such an extent as to destroy the balance of whole system, behind the blade wear, have only the airlock that more renews, cause operating cost to increase.At this situation, people take measures to improve the sealing between blade and the post shell, and measure commonly used is provided with Stamping Steel Ribbon exactly on blade, when serious gas leakage occurring, the replacing Stamping Steel Ribbon gets final product, avoid changing whole airlock, reduce user cost, still, existing Stamping Steel Ribbon wears no resistance and does not possess self compensation, quick abrasion is changed frequently, influences manufacturing efficiency.
Three. the content of model utility:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, the self compensation wear-resistant seal bar that a kind of reasonable in design, good sealing effect is provided and has the self compensation performance.
The technical solution of the utility model is: a kind of self compensation wear-resistant seal bar, contain the bar shaped body, and the sectional shape of described bar shaped body is a T font or square, and the sealing surfaces of described bar shaped body is provided with dovetail groove.
Described bar shaped body middle part is provided with cylindrical hole or cylindroid hole.
The beneficial effects of the utility model are:
1, the utility model bar shaped body middle part is provided with cylindrical hole or cylindroid hole, and such structure makes Stamping Steel Ribbon have the self compensation function, improves sealing effect.
2, the sealing surfaces of the utility model bar shaped body is provided with dovetail groove, in this dovetail groove high-abrasive material can be set, and improves wear-resisting effect.
3, the sectional shape of the utility model bar shaped body is the T font, be convenient to the blade outer fringe surface on seal groove affixed, improve join strength, prevent that effectively Stamping Steel Ribbon from coming off.
4, the utility model using scope is wide, is particularly useful for high pressure or vacuum storehouse and pressurized gas and carries, and can be reduced to a large amount of energy that keep high pressure or degree of vacuum and consume greatly, has favorable economic benefit.
Four. description of drawings:
Fig. 1 is one of structural representation of self compensation wear-resistant seal bar;
Fig. 2 is two of the structural representation of self compensation wear-resistant seal bar;
Fig. 3 is three of the structural representation of self compensation wear-resistant seal bar;
Fig. 4 is four of the structural representation of self compensation wear-resistant seal bar.
Five. embodiment:
Embodiment one: referring to Fig. 1, among the figure, self compensation wear-resistant seal bar contains bar shaped body 3, the sectional shape of bar shaped body 3 is square, and the sealing surfaces of bar shaped body 3 is provided with dovetail groove 1, in this dovetail groove 1 high-abrasive material can be set, improve wear-resisting effect.Bar shaped body 3 middle parts are provided with cylindrical hole 2, and such structure makes Stamping Steel Ribbon have the self compensation function, improve sealing effect.
Embodiment two: referring to Fig. 2, present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: bar shaped body 3 middle parts are provided with cylindroid hole 2.
Embodiment three: referring to Fig. 3, present embodiment and embodiment one are basic identical, something in common does not repeat, difference is: the sectional shape of bar shaped body 3 is the T font, its lower end is provided with horizontal edge 4, be convenient to the blade outer fringe surface on seal groove affixed, improve join strength, prevent that effectively Stamping Steel Ribbon from coming off.
Embodiment four: referring to Fig. 3, present embodiment and embodiment three are basic identical, and something in common does not repeat, and difference is: bar shaped body 3 middle parts are provided with cylindroid hole 2.
The shape that changes the sectional shape of bar shaped body, the shape that changes bar shaped body intermediate hole, change dovetail groove can be formed a plurality of embodiments, is common variation of the present utility model, does not describe in detail one by one at this.
