Abstract
The utility model discloses an outer sleeve cap for preventing leakage at the periphery of a roof ventilation pipe, and belongs to a pipeline mounting accessory. The outer sleeve cap for preventing the leakage at the periphery of the roof ventilation pipe is characterized by mainly comprising a cap and a sleeve which are connected into a whole body, wherein the sleeve is a step-shaped cylindrical sleeve and comprises an upper sleeve section, a transition sleeve and a lower sleeve section from top to bottom; the inner diameter of the upper sleeve section is larger than the outer diameter of the roof ventilation pipe; an upper limit ring and a lower stabilizing ring are arranged on the inner wall of the upper sleeve section from top to bottom; the inner diameter of the upper limit ring is smaller than that of the roof ventilation pipe; the inner diameter of the lower stabilizing ring is slightly larger than the outer diameter of the roof ventilation pipe; the inner diameter of the lower sleeve section is larger than the outer diameter of the part which covers the roof ventilation pipe and is enclosed by a waterproof coiled material; the frustum-shaped transition sleeve is arranged between the upper sleeve section and the lower sleeve section; and the spherical cap in which holes are formed is arranged on the top of the upper sleeve section. The outer sleeve cap is convenient to use and achieves good ventilation and anti-leakage effects.
Description
Technical field
The utility model metal conduit installation accessories relates in particular to a kind of overcoat pipe cap of roof vent pipe.
Background technology
At present, in the installation of roof vent pipe road and roof waterproof construction, certainly will to relate to the waterproof roll laying and be connected with the crossing of air duct, when waterproof roll is routed to the air duct place, if it is bad that process its joint portion, must cause rain water on roof to leak along the periphery of air duct; Generally take at present waterproof roll with the method for iron wire colligation at the air duct outer wall, solve being connected and leakage problems of waterproof roll and air duct edge, but antiseep is often unsatisfactory.
Summary of the invention:
The purpose of this utility model is the overcoat pipe cap that proposes a kind of roof vent pipe periphery antiseep, can effectively solve the roof waterproof coiled material lay with the air duct periphery be connected and leakage problems the quality of raising roof waterproof construction.
The purpose of this utility model is achieved like this: a kind of overcoat pipe cap (being called for short the overcoat pipe cap) of roof vent pipe periphery antiseep, it is characterized in that: the overcoat pipe cap of this roof vent pipe periphery antiseep mainly is comprised of the cap that is connected and sleeve pipe, this sleeve pipe is the stairstepping cylindrical casing, be followed successively by from top to bottom casing section, spacer shell pipeline section and cased section, internal diameter of casing section is greater than the external diameter of roof vent pipe and upper limit ring (being annular upper limit step) and lower stabilizing ring (i.e. stable step under the annular) from top to bottom are being set respectively on the inwall of upper casing section on this, and the internal diameter of this upper limit ring is less than the internal diameter of roof vent pipe, so that this overcoat pipe cap support is on roof vent pipe, and the internal diameter of lower stabilizing ring is slightly larger than the external diameter of roof vent pipe, so that this overcoat pipe cap is installed on the outer wall of roof vent pipe; The external diameter that the internal diameter of this cased section surrounds greater than the waterproof roll that is wrapped on the roof vent pipe, in addition, it is the spacer shell pipeline section of taper type between upper casing section and cased section, simultaneously, at the top of upper casing section the spheric cap is set, the bottom perimeter of this cap is offered air vent greater than the external diameter of upper casing section and at the cap body, and this cap and sleeve pipe all can adopt plastic production, this cap and sleeve pipe can separate injection moulding and make then combination, or this cap and sleeve pipe are overall injected into a whole.
During use this overcoat pipe cap is installed on the roof vent pipe, can plays good ventilation and antiseep effect.
The overcoat pipe cap of the roof vent pipe periphery antiseep that the utility model proposes, not only make simple, easy to use, solved owing to the roof waterproof coiled material is connected the bad problem that causes roof leakage with ventilating pipe, played good ventilation and antiseep effect.
The overcoat pipe cap of the roof vent pipe periphery antiseep that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the overcoat pipe cap of roof vent pipe that the utility model proposes periphery antiseep when using.
Among Fig. 1:
1, cap 2, air vent 3, lower stabilizing ring 4, upper limit ring 5, sleeve pipe 5-1, upper casing section 5-2, spacer shell pipeline section 5-3, cased section 6, waterproof roll 7, roof vent pipe.
The specific embodiment
As can be seen from Figure 1: a kind of overcoat pipe cap (being called for short the overcoat pipe cap) of roof vent pipe periphery antiseep, it is characterized in that: the overcoat pipe cap of this roof vent pipe periphery antiseep mainly is comprised of the cap 1 that is connected and sleeve pipe 5, this sleeve pipe 5 is the stairstepping cylindrical casing, be followed successively by from top to bottom casing section 5-1, spacer shell pipeline section 5-2 and cased section 5-3, internal diameter of casing section 5-1 is greater than the external diameter of roof vent pipe 7 and in that upper limit ring 4(from top to bottom is set respectively on the inwall of upper casing section 5-1 is annular upper limit step on this) and the i.e. stable step under the annular of lower stabilizing ring 3(), and the internal diameter of this upper limit ring 4 is less than the internal diameter of roof vent pipe 7, so that this overcoat pipe cap support is on roof vent pipe 7, and the internal diameter of lower stabilizing ring 3 is slightly larger than the external diameter of roof vent pipe 7, so that this overcoat pipe cap is installed on the outer wall of roof vent pipe 7, increase the stability of installing; The external diameter that the internal diameter of this cased section 5-3 surrounds greater than the waterproof roll 6 that is wrapped on the roof vent pipe 7, in addition, be the spacer shell pipeline section 5-2 of taper type between upper casing section 5-1 and cased section 5-3, simultaneously, at the top of upper casing section 5-1 spheric cap 1 is set, the bottom perimeter of this cap 1 is offered air vent 2 greater than the external diameter of upper casing section 5-1 and at the cap body, be used for ventilating and exhaust, this cap 1 and sleeve pipe 5 all can adopt plastic production, this cap 1 and sleeve pipe 5 can separate injection moulding and make then combination, or this cap 1 and sleeve pipe 5 are overall injected into a whole.
During use this overcoat pipe cap is installed on the roof vent pipe 7, can plays good ventilation and antiseep effect.
