Abstract

The utility model relates to a unit riser top hydrophobic means, including the main part, the main part is the funnel structure, and the root of its lower extreme tubulose interface encircles and is provided with fixed steel card, is provided with the aqueduct in the slope of main part bottom. The utility model discloses can pass through the pipe discharge with the water that automatic exhaust valve leaked, avoid rivers to go into in the unit riser heat preservation sponge, ensure that the unit riser is in dry environment, extension unit riser life, the installation is simple, and is with low costs, and the suitability is good, easily promotes.

Description

Unit riser top drainage device

Technical Field

The utility model relates to a hydrophobic means especially relates to a unit riser top hydrophobic means.

Background

At present, the phenomenon of leaking can appear after unit riser top self-bleeding valve is ageing or damages, because numerous, hardly in time discover and administer, the water that spills can flow downwards along the unit riser to absorbed by riser heat preservation sponge, after heat preservation sponge absorbs water to the saturated condition, the unit riser can be in wet hot state always, causes unit riser chemical corrosion, and unit riser is ageing with higher speed.

Disclosure of Invention

In order to solve the above problem, the utility model provides a can be with the drainage device in unit riser top of the rivers exhaust that unit riser top leaked, its technical scheme as follows:

the top drainage device of the unit vertical pipe comprises a main body, wherein the main body is of a funnel structure, a fixed steel clamp is arranged around the root part of a tubular connector at the lower end of the main body, and a water guide pipe is obliquely arranged at the bottom of the main body.

The main body is made of rubber, so that the rubber sealing ring is high in elasticity, good in wear resistance and not prone to water leakage.

The fixed steel clamp is of a telescopic structure, so that the drainage device at the top of the unit vertical pipe is conveniently fixed at the top of the unit vertical pipe.

The length of the water guide pipe is greater than the length of the radius of the top of the main body.

Compared with the prior art, the beneficial effects of the utility model reside in that: the water leaked by the automatic exhaust valve can be discharged through the guide pipe, the water is prevented from flowing into the unit vertical pipe heat-insulating sponge, the unit vertical pipe is ensured to be in a dry environment, the service life of the unit vertical pipe is prolonged, the installation is simple, the cost is low, the applicability is good, and the popularization is easy.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

in the figure: 1. fixed steel card, 2, aqueduct, 3, main part.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in figure 1, the top drainage device of the unit riser, the main body 3 adopts a funnel structure, the bottom of the funnel structure is 30mm long and 25mm in diameter, the device can be installed before the automatic exhaust valve is installed, and the main body 3 is tightly fixed on the top of the unit riser by a fixing steel clamp 2; a guide pipe with the diameter of 5mm is arranged at the bottom of the main body, when the automatic exhaust valve leaks water, residual water in the main body 3 can be discharged, and a sealed space is formed because the bottom of the main body 3 is tightly fixed with the top of the unit vertical pipe, so that the residual water is prevented from flowing downwards into the unit vertical pipe heat-insulating sponge.

Example 2

After the welding of a single-side screw head at the top DN20 of the unit vertical pipe is finished, a drainage device at the top of the unit vertical pipe is installed, the bottom of the drainage device is fixed by a fixing steel clamp 2, and then a valve and an automatic exhaust valve are installed. During installation, the water guide pipe 2 is required to face the corridor side, so that the automatic exhaust valve can be timely repaired or replaced after water leakage.
