Abstract
The utility model relates to a valve connection is taken over with flange, including the flange body, flange body below is provided with the takeover, be provided with the pressure gauge on the lateral wall between flange body and the takeover, ring flange lateral wall on the flange body is provided with L type weeping pipe, L type weeping union coupling has the weeping detector, bolt hole edge on the flange body up end is provided with sealing rubber pad, the utility model has the advantages of simple structure and reasonable design, set up embedded sealing rubber pad through setting up at flange body bolt hole edge, solved the ring flange and passed through the gas tightness problem that produces behind the bolted connection, improved the gas tightness of device, through set up L type weeping pipe, weeping detector and pressure gauge in joint department, the problem that appears is taken over with the discovery flange to monitoring that can be timely, has improved the security performance.
Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of valve connecting flange adapter.
Background technology
Valve is control parts in pipeline fluid induction system, is used for changing path section and media flow direction, has
Water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, from simplest stop valve
Various valves used in extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve is from atomic little
Gauge valve reach greatly the industrial pipeline valve of 10m to latus rectum.Can be used for controlling water, steam, oil product, gas, mud, various corrosion
The all kinds such as property medium, liquid metal and radioactive fluid fluidly flow.Air-tightness in valve is particularly important.One
As valve be bonded together with all kinds of pipe fittings by flange connecting pipe.Bolting face between ring flange is due to residual after lathe process
The screw thread decorative pattern stayed, after they are airtight, can produce bubble-tight problem.And the leak detection problem between joint and joint is also
Particularly important.
Based on above reason, a kind of valve connecting flange adapter is needed to be devised, by being arranged on flange body
Bolt hole edge arranges Embedded sealing rubber pad, solves the air-tightness problem produced after ring flange is bolted,
Improve the air-tightness of device；By arranging L-type leakage pipe, liquid leakage detector and piezometer in joint, can supervise in time
Survey and find flange connecting pipe produced problem, improve security performance, can be a kind of valve connecting flange adapter.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of valve connecting flange connects
Pipe.
This utility model is to be achieved through the following technical solutions: a kind of valve connecting flange adapter, including flange originally
Body, is provided with adapter, the sidewall between described flange body and adapter is provided with piezometer below described flange body；Described
Collar sidewall in flange body is provided with L-type leakage pipe, and described L-type leakage pipe connects liquid leakage detector；Described flange
Bolt hole edge on body upper surface is provided with sealing rubber pad.
Further, on the embedded bolt hole edge being fixed on flange body upper surface of described sealing rubber pad, surely
Qualitative height.
Further, described sealing rubber pad is cirque structure, is made up of natural rubber, good seal performance.
Further, the collar extension end of the lower section of described flange body and described adapter is by welding or hot melting way is in succession
Connect, weight can be reduced, save material, the function of resource optimization, and this kind of rigidity of structure is big, good integrity, hold again simultaneously
Easily ensure air-tightness and watertightness.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
Embedded sealing rubber pad is set by being arranged on flange body bolt hole edge, solves after ring flange is bolted
The air-tightness problem produced, improves the air-tightness of device；By arranging L-type leakage pipe, liquid leakage detector and pressure in joint
Power meter, can monitor and find flange connecting pipe produced problem timely, improve security performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, flange body, 2, adapter, 3, piezometer, 4, liquid leakage detector, 5, L-type leakage pipe, 6, caulking gum
Pad.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of valve connecting flange adapter, including flange body 1, is provided with adapter 2, institute below described flange body 1
State and on the sidewall between flange body 1 and adapter 2, be provided with piezometer 3；Collar sidewall in described flange body 1 is provided with
L-type leakage pipe 5, described L-type leakage pipe 5 connects liquid leakage detector 4；Bolt hole edge on described flange body 1 upper surface
It is provided with sealing rubber pad 6；On the embedded bolt hole edge being fixed on flange body 1 upper surface of described sealing rubber pad 6；
Described sealing rubber pad 6 is cirque structure, is made up of natural rubber；Outside the lower section of described flange body 1 is with described adapter 2
Mouth end is connected by welding or hot melting way docking.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
