Abstract
The utility model discloses a device for preventing water hammer phenomenon of a safety valve caused by accumulated water in an exhaust pipeline, and relates to the technical field of water hammer elimination. According to the device for preventing the water hammer phenomenon of the safety valve caused by the accumulated water in the exhaust pipeline, after the drainage pipeline is added, the drainage pipeline is caused by additionally arranging the drainage pipes at the bottoms of the exhaust pipes of all the safety valves in the waste heat boiler area, so that the condensed water of the safety valve is timely drained, the potential safety hazard is eliminated, and the using effect is better compared with that of the traditional mode.
Description
Technical Field
The utility model relates to the technical field of water hammer elimination, in particular to a device for preventing water hammer of a safety valve caused by water accumulation of an exhaust pipeline.
Background
In a pressure pipeline, the flow velocity of water is suddenly changed due to some external reasons (such as sudden closing of a valve and sudden stopping of a water pump unit), so that water hammer is caused, the hydraulic phenomenon is called water hammer or water hammer, when the water hammer is suddenly powered off or the valve is closed too fast, water flow shock waves are generated due to the inertia of pressure water flow and are like the hammer beating, so that the water hammer is called, the force generated by the water flow shock waves back and forth is sometimes large, so that the valve and the water pump are damaged, and the water hammer effect is only related to the inertia of the water and is unrelated to the water pump.
The boiler long-term operation exhaust duct easily stores the condensate water, and the condensate water can't be got rid of, easily arouses "water hammer" phenomenon when the relief valve is opened and leads to the pipeline vibrations, has the potential safety hazard, for this reason, we provide one kind and prevent to cause relief valve water hammer phenomenon device because of exhaust duct ponding.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a device for preventing water hammer of a safety valve caused by accumulated water in an exhaust pipeline, which can effectively solve the problems in the background technology.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a prevent to cause relief valve water hammer phenomenon device because of exhaust duct ponding, includes the relief valve, one side surface of relief valve is equipped with first discharge port, the one end surface of relief valve is equipped with the second discharge port, the one end surface of first discharge port is equipped with the blast pipe, the outer wall of blast pipe is equipped with the drain pipe.
Preferably, the outer surface of one end of the first exhaust port is detachably connected with the outer surface of one end of the exhaust pipe.
Preferably, the outer wall of the exhaust pipe is connected with the outer surface of one end of the drain pipe in a welding mode.
Compared with the prior art, the utility model has the following beneficial effects: this prevent to cause relief valve water hammer phenomenon device because of exhaust duct ponding, increase drainage pipe after, with all relief valve blast pipe bottoms in the exhaust-heat boiler region install the drainage tube additional and draw forth sewage pipes, make the relief valve condensate water in time get rid of, eliminate the potential safety hazard, the effect of use is better for traditional mode.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
As shown in fig. 1-3, a device for preventing water hammer of a safety valve caused by accumulated water in an exhaust pipeline comprises the safety valve 1, wherein a first discharge port 2 is arranged on the outer surface of one side of the safety valve 1, a second discharge port 3 is arranged on the outer surface of one end of the safety valve 1, an exhaust pipe 4 is arranged on the outer surface of one end of the first discharge port 2, and a drain pipe 5 is arranged on the outer wall of the exhaust pipe 4.
Further, the outer surface of one end of the first exhaust port 2 is detachably connected with the outer surface of one end of the exhaust pipe 4, and the exhaust pipe 4 can facilitate gas exhaust when in use.
Further, the outer wall of blast pipe 4 and the one end surface welded connection of drain pipe 5, drain pipe 5 can avoid blast pipe 4 to have ponding when using, can avoid the condition emergence of water hammer, and the security is higher when using.
The device for preventing the water hammer phenomenon of the safety valve caused by the accumulated water in the exhaust pipeline can be used for firstly making a scheme according to the actual production condition, measuring the size of the exhaust pipe 4 on site by technicians, prefabricating and welding the drain pipe 5, adding the drain pipe 5, additionally arranging drainage pipes at the bottoms of the exhaust pipes 4 of all the safety valves 1 in the waste heat boiler area to cause a sewage discharge pipeline, and timely discharging the condensed water of the safety valves 1 to eliminate potential safety hazards, so that the device is practical.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the utility model is defined by the appended claims and equivalents thereof.
