The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in figures 1 to 4, a flange structure for testing flange seal comprises a valve flange unit 1, a mating flange unit 2 and a plurality of sealing rings 3, wherein one side of the mating flange unit 2 is fixedly connected to the valve flange unit 1, the other side of the mating flange unit 2 is fixedly communicated to a pipeline 4, the plurality of sealing rings 3 are arranged between the valve flange unit 1 and the mating flange unit 2, under the actual working condition, the other side of the mating flange unit 2 can be not fixedly communicated to the pipeline 4 or fixedly communicated to another valve or other flange connecting parts (such as a blind plate and the like), the specific conditions can be determined according to the actual working condition, the flange structure for testing flange seal has simple structure and reasonable design, and can rapidly detect whether leakage exists between flanges at the flange connecting part of the pipeline by matching the valve flange unit and the mating flange unit, and construction is convenient, can be operated by a single person, greatly saves the use of water resources, avoids waste and is easy to popularize.
The companion flange unit 2 comprises a companion flange body 21 and a companion flange boss 22 which are integrally formed, the companion flange body 21 is of a hollow disc structure, a plurality of companion bolt holes used for connecting the companion flange unit 2 are uniformly formed in the circumferential direction of the companion flange body 21, the companion flange boss 22 is fixedly arranged on the outer wall of the companion flange body 21, one side of the companion flange body 21 is fixedly communicated to the pipeline 4, the other side of the companion flange body 21 is connected to the valve flange body 11 through a sealing ring 3 in a bolt manner, the companion flange body 21 corresponds to the valve flange body 11 one by one, and the companion flange boss 22 corresponds to the valve flange boss 12 one by one.
The water inlet end of the water inlet 211 is provided with an inlet plug screw 212, the water outlet end of the water outlet 213 is provided with an outlet plug screw 214, when the tightness of the flange is detected, a worker can plug the inlet plug screw 212 to plug the water inlet 211 and plug the outlet plug screw 214 to plug the water outlet 213, and therefore water in the pipeline 3 is prevented from leaking outwards.
2 is no less than to the quantity of sealing washer 3, and its valve flange makes sealing washer 3 receive the compression with bolted connection for the companion flange to improve the leakproofness between flange or valve and the pipeline, economical and practical.
A working principle of a flange structure for testing flange sealing is as follows:
during actual detection, after the valve is installed on the pipeline, a worker manually starts the pressure pump, the pressure pump works, water is injected into the water inlet 211 (only a small amount of water is injected, and therefore the purpose of saving water resources is achieved, the specific water amount can be determined according to actual working conditions), water in the water inlet 211 slowly flows into the space between the 2 sealing rings 3 (an annular space is formed between the 2 sealing rings 3, namely water flows into the annular space), then water in the annular space flows out from the water outlet 213, so that air in the annular space is exhausted (when the water flows out from the water outlet 213, all the air in the annular space is exhausted), the worker closes the pressure pump, the worker blocks the water outlet 213 by using the outlet plug screw 214, the worker manually starts the pressure pump, the pressure pump presses the water inlet 211, and observes the flange unit 1 of the valve, Whether the joint of the mating flange unit 2 has leakage or not is judged, if no leakage exists, the outlet plug screw 214 is taken down, the pressure pump is closed by a worker, the air gun is started, the air gun blows out water between the flanges, and then the water inlet 211 and the water outlet 213 are respectively blocked by the inlet plug screw 212 and the outlet plug screw 214; if the flange leaks, the flange connecting bolts are screwed down again or the sealing ring 3 is replaced until the flange does not leak, and the operation is finished.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
