Abstract
A kind of anti-vacuum structure of water-closing-barrel, including bend pipe, union elbow, supporting rod and check-valves；The bend pipe is arranged on overflow water inlet pipe the top peak, and the union elbow is arranged on the lower end of bend pipe；The check-valves is connected with union elbow；The supporting rod bridge piece and overflow water inlet pipe.Not only it is avoided that vacuum enters the water suck-back in water seal cylinder and external pipe in oxygen-eliminating device, but also is avoided that a large amount of cold water abruptly enter high-temperature water tank and cause equipment high vibration, so as to ensures that equipment safety uses.
Description
Technical field
Oxygen-eliminating device field is the utility model is related to, more particularly to the anti-vacuum of a kind of water-closing-barrel simple in structure, easy to operate
Structure.
Background technology
Essential element of the water-closing-barrel as atmosphere thermal deaerator, performance and security to oxygen-eliminating device play important guarantor
Barrier acts on.When water level or pressure exceed and limit, fluid column in water-closing-barrel can be washed open, have the function that to discharge water and release.And
When existing structure pressure in oxygen-eliminating device reduces and forms partial vacuum, often by the water in water-closing-barrel and external pipe
Suck-back enters in oxygen-eliminating device, and a large amount of cold water abruptly enter high-temperature water tank and can be directed at equipment high vibration, influences equipment safety use.
Defect existing in the prior art：Existing water-closing-barrel only plays the role of fluid-tight, and when forming vacuum suck-back without
Method breaking vacuum, can only leave suck-back.
The content of the invention
The utility model aim is to provide a kind of anti-vacuum structure of water-closing-barrel, solves above technical problem.
In order to realize above-mentioned technical purpose, reach above-mentioned technical requirements, technical solution is used by the utility model：
A kind of anti-vacuum structure of water-closing-barrel, including bend pipe, union elbow and check-valves；It is characterized in that：The bend pipe is arranged on excessive
Water pipe the top peak is flowed into, the union elbow is arranged on the lower end of bend pipe；The check-valves connects with union elbow
Connect；The supporting rod bridge piece and overflow water inlet pipe.
Preferably：The union elbow and check-valves are threaded connection.
Preferably：The union elbow and check-valves can also be flanged joint.
Preferably：The bend pipe and union elbow are to be welded to connect；The bend pipe and overflow water inlet pipe connect for welding
Connect, the bend pipe, supporting rod and overflow water inlet pipe are to be welded to connect.
The beneficial effects of the utility model；A kind of anti-vacuum structure of water-closing-barrel, compared with traditional structure：Not only it is avoided that true
Sky enters the water suck-back in water-closing-barrel and external pipe in oxygen-eliminating device, and is avoided that a large amount of cold water abruptly enter high-temperature water tank
Equipment high vibration is caused, so as to ensure that equipment safety uses.

In figure：1. bend pipe, 2. supporting rods, 3. union elbows, 4. overflow water inlet pipes, 5. check-valves.
Embodiment
In order to become apparent from the goal of the invention of the utility model, technical solution and its advantageous effects, below in conjunction with
The drawings and specific embodiments, are further elaborated the utility model；
In the accompanying drawings：A kind of anti-vacuum structure of water-closing-barrel, including bend pipe, union elbow and check-valves；The bend pipe 1 is set
Put and be arranged on the lower end of bend pipe 1 in 4 the top peak of overflow water inlet pipe, the union elbow 3；The check-valves 5 with
Union elbow 3 connects；2 bridge piece 1 of supporting rod and overflow water inlet pipe 4；The union elbow 3 and check-valves 5 be
It is threadedly coupled；The union elbow 3 and check-valves 5 can also be flanged joint.The bend pipe 1 and union elbow 3 are weldering
Connect in succession, to be welded to connect, the bend pipe 1, supporting rod 2 and overflow water inlet pipe 4 are for the bend pipe 1 and overflow water inlet pipe 4
It is welded to connect.
The specific implementation of the utility model：When oxygen-eliminating device normal work, when water level or pressure exceed and limit, external pipeline
Proper drainage or release, at this moment check-valves valve block close naturally；Work as work condition abnormality, when there is vacuum condition in water tank, stop at this time
Returning valve can automatically open up, and suction air is so as to breaking vacuum operating mode, so as to avoid vacuum by depositing in water-closing-barrel and external pipe
Water suck-back enters in oxygen-eliminating device, while avoids a large amount of cold water from abruptly entering high-temperature water tank and cause equipment high vibration, to ensure equipment
Safe handling.
