Abstract
The utility model discloses a freezing protection device for an inter-cooling water system of a diesel locomotive, which comprises a system pipeline. The system pipeline is provided with a drainage outlet. The periphery of the drainage outlet is provided with an installing seat. The installing seat is fixed with a shell. The inside of an inner cavity of the shell is provided with a temperature control valve communicated with the drainage outlet. As the temperature control valve is communicated on the system pipeline, when a temperature is lower than a setting temperature of the temperature control valve, the temperature control valve can be automatically opened to achieve the aim of draining the water to prevent from freezing off the pipeline or other devices in the inter-cooling water system. And the freezing protection device has simple whole structure and convenient installation, does not occupy larger space, and has flexible and reliable movement.
Description
Technical field
The utility model relates to chilled water system cryoprotection device in a kind of diesel locomotive.
Background technology
Middle chilled water system on the diesel locomotive is a close cycle loop that connects diesel engine intercooler and middle cold heat sink.Take the heat that intercooler produces to radiator by middle chilled water system, in the atmosphere around being discharged into again,, guarantee the normal operation of intercooler to reach cooling performance.But when cold weather, particularly locomotive is in stopped status for a long time, and the phenomenon that can freeze of the water in the pipeline when serious even can freezing intercooler and radiator, influence normal cycling start and uses.Do not having under the situation of cryoprotection at present, must artificial note and disposal system antifreeze, unusual trouble, as attention less than, cause the damage of system probably.
Summary of the invention
The purpose of this utility model provides a kind ofly can carry out chilled water system cryoprotection device in cryoprotection, simple in structure, the flexible movements failure-free diesel locomotive automatically, overcomes the deficiencies in the prior art.
Chilled water system cryoprotection device in the diesel locomotive of the present utility model; it comprises system pipeline; it is characterized in that: on system pipeline, offer discharge port; periphery in discharge port is provided with mount pad; on mount pad, be fixed with housing, be provided with the temperature control valve that is connected with discharge port in the inner chamber of housing.
Chilled water system cryoprotection device is provided with butt flange between wherein said housing and the mount pad in the diesel locomotive of the present utility model, is provided with pad between butt flange and the mount pad.
Chilled water system cryoprotection device in the diesel locomotive of the present utility model, the endoporus place of wherein said butt flange is provided with filter screen.
Chilled water system cryoprotection device in the diesel locomotive of the present utility model, owing to be communicated with temperature control valve on system pipeline, when temperature was lower than the setting temperature of temperature control valve, temperature control valve can be opened automatically, reach the purpose that discharges water, to prevent pipeline or other equipment in the freezing middle chilled water system; Integral structure is simple, and good the installation do not take than large space, and flexible movements are reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the structural representation of butt flange and housing and temperature control valve among Fig. 1.
The specific embodiment
As shown in Figure 1, 2: 1 is the middle chilled water system pipeline on the diesel locomotive, is processed with discharge port 11 on this pipeline 1, is welded with mount pad 2 at the periphery of discharge port 11.
4 is butt flange, and 5 is housing, between housing 5 and the butt flange 4 for welding or be threaded.The pressure cap 8 that has been threaded at the endoporus place of butt flange 4 has clamped filter screen 7 between the termination of pressure cap 8 and housing 5, is processed with to remove hole 9 and be used for tightening of spanner on pressure cap 8.
Be bolted to connection between butt flange 4 and the mount pad 2, between butt flange 4 and mount pad 2, be provided with packing seal 3.
Inner chamber 10 places at housing 5 are provided with the temperature control valve of selecting for use 6, and the outside of housing 5 is stretched out in the termination of temperature control valve 6.
The position of above-mentioned discharge port 11 is located at the nadir place on the pipeline 1, to make things convenient for draining.
After the installation, according to the weather temperature unlatching temperature and the closing temperature of temperature control valve 6 are set up appropriate value, general temperature control valve 6 self-opening drainings when temperature is lower than design temperature as 4.4 ℃, 1.7 ℃ the time complete opening and without any need for the external force effect, this makes system's emptying cooling water expansion tank fully rapidly before bursting by freezing; When temperature is raised to 1.7 ℃, begin to close, close fully in the time of 4.4 ℃, thereby the system that makes resumes work rapidly.
