Description

Municipal administration heating power pipeline sluicing device

Technical Field

The invention relates to a municipal heating pipeline water drainage device, and belongs to the field of heat supply.

Background

According to the design specification of urban heat supply pipe networks, a water drainage device is required to be installed at a low point of a hot water pipeline, a water drainage inspection well is arranged at the same time, the water drainage device is arranged to rapidly drain water in the pipeline under the pipeline accident state, conditions are provided for rush repair of workers, the rush repair time is shortened, and impurities such as sludge in the pipeline during the trial operation of the pipeline are removed at the low point.

The traditional thermal drainage adopts a drainage well, but the drainage well has a plurality of defects.

1. Most of the drainage wells are arranged at the low points of the pipeline system, the drainage wells are deep, the maximum depth of the drainage wells is 6 meters, people are inconvenient to go up and down, the interior of the inspection well is sealed, harmful gas poisoning easily occurs once ventilation is insufficient, and suffocation accidents are caused.

2. The main and auxiliary well structures are adopted for the drainage well for safety, the structure is a concrete structure, the engineering investment of the drainage well is large, and although the concrete structure is adopted, the detailed construction of a casing pipe and the like is not in place in the construction, so that water enters the well and pipelines and valves are seriously corroded.

3. The main and auxiliary shaft structure occupies a large space on urban roads, and influences the arrangement of other pipelines.

Disclosure of Invention

The utility model provides a municipal administration heating power pipeline sluicing device solves the interior maintenance of heating power pipeline and carries out waste water and get rid of a great deal of problem that sets up the sluicing well and appear.

In order to achieve the above object, the utility model adopts the following technical scheme:

the municipal thermal pipeline water drainage device comprises a three-way pipe respectively arranged on a water inlet thermal pipeline and a water return thermal pipeline, wherein the three-way pipe is vertically arranged and welded on the pipe wall of the thermal pipeline, a valve is arranged at the upper part of the three-way pipe, a water drainage pipe which is transversely arranged is connected above the valve, a water drainage valve is arranged on the water drainage pipe, and the top of the three-way pipe is blocked by a flange.

Preferably, the three-way pipe is led into the manhole well towards the upper end, a concrete preset part with the depth of 1.2 meters is buried above the heat distribution pipeline in the manhole well, and the valve of the three-way pipe is located in the manhole well.

Preferably, the end part of the drain pipe is provided with a hose quick connector, and the quick connector is provided with a blank cap.

Preferably, the thermal pipeline provided with the three-way pipe is positioned at the low point of the hot water pipeline.

The utility model discloses there are following a great deal of advantages, and the security is high, and the people don't go into the well indoor just can solve the pipeline and sluices the problem, ensures personnel's life safety, and this novel sluicing device operation is got up convenient easy, can let the staff accomplish sluicing and impurity removal's work fast. The investment cost is low, the scheme saves the investment compared with the arrangement of a huge main well and auxiliary well concrete structure, simultaneously reduces the occupied area on urban roads and does not influence other pipelines. This novel heating power sluicing device, the simple convenient operation of installation saves the investment, promotes convenient to use.

Reference numerals:

1. the system comprises a thermal pipeline, a three-way pipe, a valve, a water drain valve, a flange plug, a quick connector, a cover, a manhole well, a water drain pipe and a water drain pipe, wherein the thermal pipeline comprises 2, the three-way pipe, 3, the valve, 4 and the water drain valve, 5 and the flange plug, 6 and the quick connector, 7 and the cover.

Detailed Description

The specific structure of the present invention is further described below:

municipal administration heating power pipeline sluicing device is including setting up three-way pipe 2 on intaking and return water heating power pipeline 1 respectively, and three-way pipe and the manpower pipeline that connects adopt the prefabricated finished product pipe to install on heating power pipeline, and heating power pipeline 1 of three-way pipe 2 is in the low point position of hot water pipeline. The three-way pipe 2 is vertically arranged and welded on the pipe wall of the thermal power pipeline 1, the upper part of the three-way pipe 2 is provided with a valve 3, the valve 3 is connected with a transversely arranged drain pipe 9, the drain pipe 9 is provided with a drain valve 4, and the top of the three-way pipe 2 is blocked 5.

The three-way pipe 2 is introduced into a manhole well 8 towards the upper end, a concrete preset part with the depth of 1.2 m is embedded above the thermal pipeline 1 in the manhole well 8, the valve and the water drain valve are both arranged in a hand hole well with the depth of 1.2 m below the ground, and the manhole faces the three-way pipe. The end part of the water drain pipe 9 is provided with a hose quick connector 6, and the position of the quick connector 6 is provided with a blank cap 7.
