Abstract
The utility model relates to a high-lift packing seal structure, which comprises a packing gland, a packing shaft sleeve, fillings, a water sealing pipe part, a packing ring and a pump casing. a closed cavity is formed by the packing shaft sleeve, the inner side surface and the inner end surface of the pump casing, and the packing gland. The fillings and the packing ring are arranged in the cavity. The pump casing is provided with a connecting port used for being connected with the water sealing pipe part. The high-lift packing seal structure is characterized in that the packing ring is arranged next to the inner end surface of the pump casing. A flushing water port communicated with the connecting port is positioned around the packing ring and is arranged inside the pump casing, so that the high-pressure water outside the pump casing can flow into the cavity through the water sealing pipe part. The high-lift packing seal structure has the advantages of simple structure, and convenient installation and repacking. Since the packing ring is just next to the inner end surface of the pump casing, the placement location of the packing ring is free from the influence of fillings. Therefore, the packing ring and the flushing water port are prevented from mismatching with each other in location. As a result, the sealing effect is greatly improved.
Description
Technical field
The utility model relates to fluid sealing, the particularly sealing configuration of high-lift filler.
Background technique
See also Fig. 1, shown in Figure 1 is a kind of packing seal form of routine, comprise, Gland (not drawing among the figure), packing sleeve 1, filler 2, water sealing (sealing water) pipe parts 3, packing ring 4 and pump case 5, wherein, the inner side surface of described packing sleeve, pump case and interior edge face, Gland surround an airtight chamber, and described filler and packing ring all are positioned at chamber, and pump case is provided with the connection mouth that water supply tube sealing parts connect.Be not difficult to find out, the placement location of packing ring, influenced by the decrement of the filler about it, wayward, namely in assembly process, when Gland compresses filler, the situation of dislocation appears in the flushing mouth of a river that is easy to generate packing ring and pump case, make in applying to high-lift process, it is tight sealing to occur, the situation that leakage rate is excessive.
The model utility content
The utility model purpose is to solve packing ring and the flushing mouth of a river this problem that misplaces, and has proposed a kind of sealing configuration of novel high-lift filler.
To achieve these goals, the utility model is achieved in that the sealing configuration of high-lift filler, comprise: Gland, packing sleeve, filler, the water sealing (sealing water) pipe parts, packing ring and pump case, wherein, described packing sleeve, the inner side surface of pump case and interior edge face, Gland surrounds an airtight chamber, described filler and packing ring all are positioned at chamber, pump case is provided with the connection mouth that water supply tube sealing parts connect, it is characterized in that: described packing ring is close to the interior edge face of pump case, be provided with a flushing mouth of a river and this flushing mouth of a river in the packing ring place in the pump case and be connected with described connection mouth, make extraneous high pressure water in the water sealing (sealing water) pipe parts can enter described chamber.
Preferably, the described flushing mouth of a river comprises and first aperture of radially extending corresponding with described packing ring and is connected with first aperture and second aperture of horizontal expansion that described connection mouth is connected with second aperture.That end of the close Gland in described second aperture extends to the exterior edge face of pump case always, and this end seals by Sealing.
Advantage of the present utility model: simple in structure, be convenient to install and change filler, because the adjacent pump case interior edge face of packing ring, its placement location is not subjected to the influence of filler, so the situation of dislocation can not appear in packing ring and the flushing mouth of a river, improves sealing effect greatly.

Fig. 2 is structural representation of the present utility model.
Fig. 3 is the enlarged diagram of pump case part among Fig. 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Shown in Fig. 2 and 3 is a kind of sealing configuration of novel high-lift filler, comprise: Gland (not drawing among the figure), packing sleeve 1, filler 2, water sealing (sealing water) pipe parts 3, packing ring 4 and pump case 5, wherein, described packing sleeve, the inner side surface of pump case and interior edge face, Gland surrounds an airtight chamber, described filler and packing ring all are positioned at chamber, pump case is provided with the connection mouth 6 that water supply tube sealing parts connect, it is characterized in that: described packing ring is close to the interior edge face of pump case, be provided with a flushing mouth of a river 7 and this flushing mouth of a river in the packing ring place in the pump case and be connected with described connection mouth, make extraneous high pressure water in the water sealing (sealing water) pipe parts can enter described chamber.
The described flushing mouth of a river comprises and first aperture 8 of radially extending corresponding with described packing ring and is connected with first aperture and second aperture 9 of horizontal expansion that described connection mouth is connected with second aperture.Described second aperture extends to the exterior edge face of pump case near that end of Gland always, and this end is by Sealing 10(such as, bolt) sealing.This kind structure without blowhole, and is used mechanical punching when purpose is to cast pump case, and is so namely easy to process, can guarantee the castability of pump case again.
During assembling, earlier packing sleeve and pump case assembly unit, successively packing ring, filler are packed in the cavity again, seal with Gland at last.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
