Abstract

The utility model relates to a ground buried steam pipeline drainage device. A water collection hopper is arranged under a steam pipeline, and the water collection hopper is connected with a valve and a water drainage device through a drainage pipe. The ground buried steam pipeline drainage device is characterized in that a flow guide baffle is arranged at a connecting opening part of the water collection hopper and the steam pipeline, and one side of the flow guide baffle plate facing the air flow direction is welded on the inner wall of the steam pipeline. The ground buried steam pipeline drainage device has the advantages that the structure is simple, the manufacture is convenient, the flow guide baffle plate is arranged at the connecting opening part of the water collection hopper and the steam pipeline, the blockage of the water collection hopper caused by impurities during the blowing sweeping is avoided, the water drainage smoothness is ensured, the normal operation of the steam pipeline is ensured, and the maintenance workload and the cost are reduced.

Description

Bury the ground draining apparatus for steam conduit

Technical field

The utility model relates to a kind of pipe-line system, especially relates to a kind of follow-on ground draining apparatus for steam conduit that buries, and is used for the condensed water of steam in the exhaust steam pipeline.

Background technique

At present, bury that employed steam trap connection has characteristics such as simple in structure, engineering cost is few in the ground steam line, be widely used in the pipe-line transportation systems such as thermoelectricity, heating, the market demand is very big.But generally bury the steam trap connection of ground steam tube at present, as shown in Figure 1, steam line 5 ' be arranged with drip pan 4 ', drip pan 4 ' by drain pipe 3 ' connections valve 1 ' and STEAM TRAP 2 ', in the purging before pipeline is brought into use, ducted foreign material reach easily be blown into drip pan 4 ', thereby cause the obstruction of whole steam trap connection, cause steam trap connection to lose efficacy and condensed water in can't the exhaust steam pipeline, thereby influence the normal operation of steam line, and maintenance difficult.

The model utility content

The applicant has carried out research and has improved at above-mentioned problem, and a kind of ground draining apparatus for steam conduit that buries is provided, and avoids steam trap connection to be stopped up by foreign material, guarantees the normal operation of steam line, reduces maintenance load.

In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of ground draining apparatus for steam conduit that buries, have drip pan at steam line, drip pan connects valve and STEAM TRAP by drain pipe, and the connection mouth place of described drip pan and steam line is provided with flow apron, and the face down bonding that described flow apron is met to airflow direction is connected on the inwall of steam line.

Further:

The cross section of described flow apron is V-shaped.

Technique effect of the present utility model is:

The disclosed a kind of ground draining apparatus for steam conduit that buries of the utility model, simple in structure, easy to make, connection mouth place at drip pan and steam line is provided with flow apron, foreign material stop up drip pan when avoiding purging, guarantee hydrophobic unimpededly, guarantee the normal operation of steam line, and reduce the workload and the cost of maintenance.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Shown in Fig. 2,3, have drip pan 4 at steam line 5, drip pan 4 connects valve 1 and STEAM TRAP 2 by drain pipe 3, between drip pan 4 and the steam line 5 connection mouth 401 is arranged, can flow in the drip pan 4 by connection mouth 401 steam condensates, flow apron 6 is arranged on the top of connection mouth 401, and the face down bonding that flow apron 6 is met to airflow direction (arrow B) is connected on the inwall of steam line 5, and the cross section of flow apron 6 is V-shaped.When carrying out the steam line purging, flow apron 6 stops that foreign material enter drip pan 4, and foreign material are blown along flow apron 6, and can deposit in the drip pan 4 under the effect of air-flow in the pipeline, thereby makes steam trap connection keep unimpeded.And when delivering vapor, condensed water can enter drip pan 4 by the gap between flow apron 6 and the steam line 5, by drain pipe 3, valve 1 and STEAM TRAP 2 condensed water is discharged at last.

Claims

1. one kind is buried the ground draining apparatus for steam conduit, have drip pan at steam line, drip pan connects valve and STEAM TRAP by drain pipe, it is characterized in that: the connection mouth place of described drip pan and steam line is provided with flow apron, and the face down bonding that described flow apron is met to airflow direction is connected on the inwall of steam line.

2. according to the described ground draining apparatus for steam conduit that buries of claim 1, it is characterized in that: the cross section of described flow apron is V-shaped.
