Abstract
The utility model provides a flange seal structure, includes examination clamp plate, winding pad, spacer ring, be equipped with boss I, boss II on the examination clamp plate, I diameter of boss is the passageway diameter in the valve, I height ratio winding pad thickness height of boss, the winding pad external diameter is II diameters of boss, II highly be less than spacer ring thickness of boss, the spacer ring internal diameter is the winding pad external diameter, the spacer ring external diameter is less than the valve collar and connects the face internal diameter. The beneficial effects of the utility model are that, carry on spacingly to winding gasket through boss I, boss II with spacer ring, pressure testing board, guaranteed the leakproofness and the adjustability of winding pad, improved valve housing seal test's success rate, protected the ring connection face of valve simultaneously, promoted valve assembly efficiency.
Description
Technical Field
The utility model relates to a flange seal structure, especially a seal structure of flange department during valve housing pressure testing.
Background
The existing sealing structure at the flange for pressure test of the valve shell is characterized in that an open O-shaped rubber ring is embedded on a test pressing plate with a dovetail groove, and the sealing structure can only be used for low-pound valves.
To high pound level valve, the valve flange sealing face is mostly the ring connection face, and the flange seal adopts eight corner pad to seal mostly when carrying out this type of valve housing strength test, processes out the ring connection face the same with valve end flange size promptly on the pressure testing board. However, the octagonal gasket is high in purchase cost and high in assembly precision requirement, if the octagonal gasket is improperly assembled, the annular connecting surface of the valve to be tested is easy to damage, the octagonal gasket cannot be repeatedly assembled, and the sealing performance is seriously reduced after the octagonal gasket is repeatedly assembled.
SUMMERY OF THE UTILITY MODEL
In order to overcome the prior art problem, the utility model provides a flange seal structure.
The technical scheme of the utility model, a flange seal structure, including examination clamp plate, winding pad, spacer ring, be equipped with boss I, boss II on the examination clamp plate, I diameter of boss is the valve inside passage diameter, I height ratio winding pad thickness height of boss, the winding pad external diameter is II diameters of boss, II highly being less than spacer ring thickness of boss, the spacer ring internal diameter is the winding pad external diameter, the spacer ring external diameter is less than valve collar connection face internal diameter.
The beneficial effects of the utility model are that, carry on spacingly to winding gasket through boss I, boss II with spacer ring, pressure testing board, guaranteed the leakproofness and the adjustability of winding pad, improved valve housing seal test's success rate, protected the ring connection face of valve simultaneously, promoted valve assembly efficiency.
