Abstract
The utility model relates to an exhausting and freezing preventing device of a compressed air transmission pipeline. A storage tank is connected to the lower portion of an overhead compressed air pipe network through an exhausting pipe, the lower portion of the storage tank is fixed in a heat preservation sleeve, a steam inlet valve and a steam trap valve which are communicated with an inner cavity of the heat preservation sleeve are fixed on the heat preservation sleeve, and an exhausting valve which is communicated with an inner cavity of the storage tank is fixed at the bottom of the storage tank. The exhausting and freezing preventing device of the compressed air transmission pipeline is simple in structure, and effectively solves the problem that condensate water in the compressed air pipe network is frozen in winter.
Description
Technical field
The utility model relates to a kind of compressed air tunnel blowdown anti-icer.
Background technique
In large and medium-sized enterprise, pressurized air relies on the long distance of pipe network to flow to each production unit.Owing to contain a large amount of condensed waters in the pressurized air, for avoiding condensed water along with pressurized air directly enters in the production unit equipment, affect the normal use of equipment, pipe network is when design, blowdown valve (using diameter 25mm seamless steel pipe to connect ball valve) draining is installed below the pipeline lowest part, relies on post operator on duty's timing drainage, blowdown.Pressurized air condensed water in pipeline cold season because in time draining makes sewage disposal facility be easy to freeze, causes the pipe network lower to freeze in the winter time, affects the pressurized air regular supply, makes to produce to be forced to interrupt.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of compressed air tunnel anti-freezing and pollution-discharging device, and it is simple in structure, has effectively solved compressed air pipe network condensed water in the winter problem that freezes.
The technical scheme in the invention for solving the technical problem is: the below of built on stilts compressed air pipe network connects storage tank by drain pipe, the bottom of storage tank is fixed in the lagging, be fixed with the steam inlet valve and the Automatic steam trap Trap that communicate with the lagging inner chamber on the lagging, the fixing blowdown valve that communicates with the storage tank inner chamber in the bottom of described storage tank.
The utility model has solved compressed air pipe network condensed water in the winter problem that freezes, and guarantees the normal use of pressurized air without interruption and production unit equipment in the winter time; Simultaneously, prolong post operator on duty's pumpway every, raise labour efficiency, reduce labor intensity.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the utility model schematic representation.
Embodiment
As shown in Figure 1, the below of built on stilts compressed air pipe network 1 connects storage tank 2 by drain pipe 7, the bottom of storage tank 2 is fixed in the lagging 3, is fixed with the steam inlet valve 4 and the Automatic steam trap Trap 5 that communicate with lagging 3 inner chambers on the lagging 3, guarantees that the condensed water in drain pipe 7 and the storage tank 2 does not freeze.The fixing blowdown valve 6 that communicates with storage tank 2 inner chambers in the bottom of described storage tank 2, regularly discharging.
Described blowdown valve 6 is solenoid valve, and solenoid valve is controlled by time circuit, can realize automatic-discharging.
Claims (2)
