Abstract

The utility model provides a riser inspection opening structure relates to a body structure. It has solved the poor problem of riser inspection socket shutoff leakproofness among the prior art. The vertical pipe inspection port structure comprises a vertical pipe body and an inspection port arranged on the vertical pipe body, wherein the port edge of the inspection port is provided with a pressure-bearing rubber ring facing the inspection port plugging cover, and the pressure-bearing rubber ring is partially embedded into the port edge of the inspection port. The elastic pressure-bearing rubber ring improves the contact area between the sealing cover and the edge of the inspection opening under the jacking pressure of the sealing cover, thereby improving the sealing property, having smaller required force and being capable of being screwed by only one hand. The utility model discloses the trapezoidal design of terminal surface, rubber ring pre-compaction volume one hand are screwed, thoroughly solve the construction problem of leaking, and very big convenient construction is used to stopped follow-up hidden danger problem of leaking, simple structure, convenient operation, it is with low costs.

Description

Riser inspection hole structure

Technical Field

The utility model belongs to the technical field of the drainage pipe way, a body structure is related to, especially a riser inspection socket structure.

Background

Currently, pipe mills primarily use polyvinyl chloride (PVC) materials to produce pipe products. Polyvinyl chloride (PVC) plastic is one of five common plastics. PVC was the earliest (1872) plastic pipe material used for commercial production (1936) and is still one of the world's largest thermoplastics to date.

The steel pipe has the advantages of good chemical resistance of ①, no rust, good self-extinguishing property and flame retardance of ②, good aging resistance of ③, long service life, good electrical property of ④, high volume resistance and breakdown voltage, smooth inner and outer walls of ⑤, high fluid conveying capacity, light weight of ⑥ compared with a steel pipe, capability of bonding, convenience in installation, installation and construction workload of 1/2 of the steel pipe, 82-degree glass transition temperature of ⑦ and use temperature of no more than 50-degree generally.

At present, PVC pipelines are still popularized and used as mainstream products in the building industry, but the following problems exist in practical application: the sealing and water leakage problems of the PVC vertical pipe inspection port always troubles construction and application, the sealing cover of the vertical pipe inspection port needs to be screwed by large external force to ensure the sealing property, and inconvenience is brought to construction, installation and later inspection and use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a riser inspection socket structure, this riser inspection socket structure improves riser inspection socket sealing performance, reduces the power of screwing, easy to assemble and use.

The purpose of the utility model can be realized by the following technical proposal: a vertical pipe inspection port structure comprises a vertical pipe body and an inspection port arranged on the vertical pipe body, wherein a pressure-bearing rubber ring facing an inspection port plugging cover is arranged on the port edge of the inspection port, and the pressure-bearing rubber ring is partially embedded into the port edge of the inspection port. The elastic pressure-bearing rubber ring improves the contact area between the sealing cover and the edge of the inspection opening under the jacking pressure of the sealing cover, thereby improving the sealing property, having smaller required force and being capable of being screwed by only one hand.

In certain embodiments, the pressure-bearing rubber ring is trapezoidal in cross section.

In some embodiments, after the plugging cover is screwed, the pressure-bearing end face of the pressure-bearing rubber ring is pressed down by 50 threads, so that a better sealing effect can be obtained with a smaller screwing pressure.

In some embodiments, the riser body is PVC.

In some embodiments, the inspection opening sealing cover on the riser body is a spinning sealing cover, that is, the sealing cover is fixed with the inspection opening by matching threads.

Compared with the prior art, the vertical pipe inspection hole structure has the following advantages:

the utility model discloses the trapezoidal design of terminal surface, rubber ring pre-compaction volume one hand are screwed, thoroughly solve the construction problem of leaking, and very big convenient construction is used to stopped follow-up hidden danger problem of leaking, simple structure, convenient operation, it is with low costs.

Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments. The following embodiments do not limit the invention to which the claims refer. Moreover, all combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

Examples

As shown in fig. 1, the vertical pipe inspection hole structure includes a vertical pipe body 1 and an inspection hole 2 disposed on the vertical pipe body, wherein the vertical pipe body is made of PVC. The opening edge of the inspection opening is provided with a pressure-bearing rubber ring 3 facing the blocking cover of the inspection opening, the pressure-bearing rubber ring is partially embedded into the opening edge of the inspection opening, and the section of the pressure-bearing rubber ring is trapezoidal. After the plugging cover is screwed, the pressure-bearing end face of the pressure-bearing rubber ring is pressed down by 50 threads, so that the pressing amount can obtain a better sealing effect under a smaller screwing pressure. The inspection opening plugging cover on the vertical pipe body is a spinning plugging cover 4, a thread 5 is arranged on the inspection opening, and the plugging cover is fixedly connected with the inspection opening through thread matching. The elastic pressure-bearing rubber ring improves the contact area between the sealing cover and the edge of the inspection opening under the jacking pressure of the sealing cover, thereby improving the sealing property, having smaller required force and being capable of being screwed by only one hand.
