Abstract
A screw flange gland type connecting piece for a mute drainage pipeline. Including protruding circle, gland, clamping ring, sealing rubber ring, connecting pipe, its characterized in that: sealing rubber rings abutted to flange faces are arranged between the connecting pipe and the upper connecting pipe and between the connecting pipe and the lower connecting pipe respectively, pressing rings are arranged on the connecting pipe and the sealing rubber rings between the upper connecting pipe and the lower connecting pipe respectively, the upper pressing cover and the lower pressing cover are sleeved on the outer diameters of the upper connecting pipe and the lower connecting pipe respectively, the convex rings connected with the pressing covers are abutted to the pressing rings respectively, and the upper pressing cover and the lower pressing cover are connected with the upper connecting pipe and the lower connecting pipe through internal threads. Compared with the prior art, the connecting pipe fitting with the pressure sealing structure in the sealing rubber ring is compact in connection and convenient to maintain, and can effectively guarantee long-term high-efficiency sealing of the connecting pipe fitting.
Description
Technical Field
The utility model relates to a screw flange gland formula connecting piece for silence drainage pipe relates to silence drainage pipe manufacturing and designing technical field, is applied to the connection of drain pipe.
Background
At present, the domestic drainage pipeline comprises a groove connecting pipe fitting, when the sealing rubber ring is connected, the contact surface is small, leakage points are easy to generate, the sealing effect cannot be achieved, the internal drainage pipeline is easy to age or deform due to the fact that the internal drainage pipeline is in direct contact with air or water, the internal drainage pipeline is exposed to the sun and can generate water leakage phenomenon in time, particularly, after the internal drainage pipeline is connected with a pipeline of a building, the maintenance of the leakage points is relatively difficult, and inconvenience is brought to the life of residents.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at improves current drainage pipe connection pipe fitting, designs the connection pipe fitting of pressing seal structure in the rubber gasket, connects compactly, and easy maintenance can effectively guarantee to connect the long-term high-efficient sealed screw flange gland formula connecting piece for silence drainage pipe of pipe fitting.
Its technique is realized like this, including protruding circle, gland, clamping ring, rubber seal ring, connecting pipe, its characterized in that: sealing rubber rings which are abutted against flange surfaces are respectively arranged between the connecting pipe and the upper connecting pipe and between the connecting pipe and the lower connecting pipe, pressing rings are respectively arranged on the sealing rubber rings between the connecting pipe and the upper connecting pipe and between the connecting pipe and the lower connecting pipe, the upper gland and the lower gland are respectively sleeved on the outer diameters of the upper connecting pipe and the lower connecting pipe, the convex rings connected with the glands are respectively abutted against the pressing rings, and the upper gland and the lower gland are connected with the upper connecting pipe and the lower connecting pipe through internal threads;
the inner diameter of the connecting pipe is the same as that of the upper connecting pipe and the lower connecting pipe, and two ends of the connecting pipe are respectively provided with a flange surface;
the connecting pipe is arranged between the upper connecting pipe and the lower connecting pipe.
The obvious advantages and effects after the technology is implemented are as follows: compared with the prior art, the connecting pipe fitting with the sealing structure in the sealing rubber ring is compact in connection, convenient to maintain and capable of effectively guaranteeing long-term efficient sealing of the connecting pipe fitting.
Drawings
FIG. 1 is a schematic sectional view of the present invention;
wherein, 1-upper connecting pipe, 2-convex ring, 3-gland, 4-pressing ring, 5-sealing rubber ring, 6-connecting pipe, 7-lower connecting pipe, 8-flange surface.
Detailed Description
The invention will be further described with reference to the following connection of HDPE pipes with the accompanying drawings:
referring to fig. 1, a connection pipe 6 is provided between an upper connection pipe 1 and a lower connection pipe 7. Sealing rubber rings 5 which are abutted against flange faces 8 are respectively arranged between a connecting pipe 6 and the upper connecting pipe 1 and the lower connecting pipe 7, pressing rings 4 are respectively arranged on the sealing rubber rings 6 between the connecting pipe 6 and the upper connecting pipe 1 and the lower connecting pipe 7, an upper gland 3 and a lower gland 3 are respectively sleeved on the outer diameters of the upper connecting pipe 1 and the lower connecting pipe 7, convex rings 2 which are connected with the glands 3 are respectively abutted against the pressing rings 4, and the upper gland 3 and the lower gland 3 are connected with the upper connecting pipe 1 and the lower connecting pipe 7 through internal threads;
the inner diameter of the connecting pipe 6 is the same as that of the upper connecting pipe 1 and the lower connecting pipe 7, and the two ends are respectively provided with a flange surface 8
Referring to the attached drawing 1, an upper connecting pipe 1, a convex ring 2, a gland 3, a pressing ring 4, a sealing rubber ring 5, a connecting pipe 6 and a lower connecting pipe 7 are processed respectively.
During connection, the upper connecting pipe 1 and the lower connecting pipe 7 are sleeved with the gland 3, the pressing ring 4 and the sealing rubber ring 5 in sequence in opposite directions respectively, then one ends of the upper connecting pipe 1 and the lower connecting pipe 7 are sleeved with two ends of the connecting pipe 6 respectively, the gland 3 is screwed into two ends of the connecting pipe 6 respectively through threads, the pressing ring 4 is pressed down through the gland 3 by the way, the sealing rubber ring 5 is driven to abut against flange faces 8 at two ends of the connecting pipe 6 respectively, the gland 3 is further screwed in, the sealing rubber ring 5 is compacted, the effect of sealing two ends is achieved, and connection of the upper connecting pipe 1 and the lower connecting pipe 7 is completed.
