Abstract
The utility model discloses a kind of bellows shaped by fluid pressure seal arrangement, comprise seal shaft and two O RunddichtringOs, seal shaft is set with two installation sleeves side by side, two installation sleeves are respectively installed with gasket ring, described two O RunddichtringOs to be set on two installation sleeves and near gasket ring one end, be threaded connection locking nut in path one end of seal shaft, described two installation sleeves realize location by locking nut.Beneficial effect is: easy accessibility, can enhance productivity; Reduce the shearing force that O-ring seals is suffered in feeding process, improve working life and the quality of product of O-ring seals, make O RunddichtringO not fragile, long service life, can quality of product be guaranteed.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of bellows shaped by fluid pressure seal arrangement.
Background technique
Existing bellows shaped by fluid pressure seal arrangement comprises seal bar and is sleeved on two O-ring seals in seal bar, and wherein seal bar is that stainless steel material is made.The seal bar feeding of first both sides when bellows shaped by fluid pressure, after sealing is carried out to pipe again to carrying out topping up in pipe, suppress, shaping.
There are the following problems for this bellows shaped by fluid pressure seal arrangement: because briquetting pressure is larger during work, for guaranteeing sealing effect, certain magnitude of interference is had between seal ring and pipe, after repeatedly using, due to the effect by shearing force, seal ring meeting well damage, easily affects the quality of molding product, even cause waste product, frequent seal ring of changing also can cause manufacturing efficiency low.
Model utility content
It is not fragile that technical problem to be solved in the utility model is to provide a kind of easy accessibility, seal ring, long service life, can guarantee the bellows shaped by fluid pressure seal arrangement of quality of product.
For solving the problem, the utility model adopts following technological scheme:
A kind of bellows shaped by fluid pressure seal arrangement, comprise seal shaft and two O RunddichtringOs, its special way is: on seal shaft, be set with two installation sleeves side by side, two installation sleeves are respectively installed with gasket ring, described two O RunddichtringOs to be set on two installation sleeves and near gasket ring one end, be threaded connection locking nut in path one end of seal shaft, described two installation sleeves realize location by locking nut.
Preferably, described two installation sleeves are respectively the first installation sleeve and the second installation sleeve, and wherein the first installation sleeve endoporus is stepped and coordinates with the pivot clearance of on seal shaft.
Preferably, between the first installation sleeve endoporus and the annular end face of the seal shaft shaft shoulder, be provided with combination seal pad, to prevent from leaking at scyewed joint place during topping up, affect quality of product and molding effect, thus improve the reliability of sealing.
Preferably, described gasket ring is that nylon material is made.
The beneficial effects of the utility model are: because O RunddichtringO is arranged on seal shaft by installation sleeve, and realize location by locking nut, and therefore easy accessibility, can enhance productivity; Owing to being respectively installed with gasket ring on installation sleeve, O RunddichtringO is near gasket ring one end, therefore, it is possible to reduce O-ring seals shearing force suffered in feeding process, improve working life and the quality of product of O-ring seals, make O RunddichtringO not fragile, long service life, can guarantee quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: seal shaft 1, combination seal pad 2, first installation sleeve 3, gasket ring 4, O RunddichtringO 5, second installation sleeve 6, locking nut 7.
Embodiment
As shown in the figure, a kind of bellows shaped by fluid pressure seal arrangement that the utility model relates to, comprise seal shaft 1 and two O RunddichtringOs 5, seal shaft 1 is set with two installation sleeves side by side, two installation sleeves are respectively the first installation sleeve 3 and the second installation sleeve 6, the outer rim of two installation sleeves is stepped, and wherein the first installation sleeve 3 endoporus is stepped and coordinates with the pivot clearance of on seal shaft 1.
First installation sleeve 3 and the second installation sleeve 6 are respectively installed with gasket ring 4, and gasket ring 4 leans against the ladder place of corresponding installation sleeve outer rim, and described two O RunddichtringOs 5 to be set on two installation sleeves and near gasket ring 4 one end.Be threaded connection locking nut 7 in path one end of seal shaft 1, the external diameter of the external diameter of locking nut 7 and two installation sleeves is suitable, the axially locating that described two installation sleeves are realized on seal shaft 1 by locking nut 7.
Described gasket ring 4 is made for the nonmetallic material such as nylon or polytetrafluoro.As preferably, described gasket ring 4 is made for nylon material.
Between the first installation sleeve 3 endoporus and the annular end face of seal shaft 1 shaft shoulder, be provided with combination seal pad 2, to prevent from leaking at scyewed joint place during topping up, affect quality of product and molding effect, thus improve the reliability of sealing.
During use, because O RunddichtringO 5 is near gasket ring 4 one end, therefore, it is possible to reduce O-ring seals shearing force suffered in feeding process, improves working life and the quality of product of O RunddichtringO 5, make O RunddichtringO 5 not fragile.Once seal ring damages, unload lock jack panel 7, just can take off two installation sleeve replacement o seal rings 5, convenient to disassembly.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and mode of execution utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
