This water hammer absorber overall structure is simple, is connected through a screw thread section and pipeline or valve body is easy to connect and disassembly is also square
Just, threaded connection section is easy to process, and manufacturing cost is low, high in machining efficiency, tube body good integrity, no leak source, long service life.
In a kind of above-mentioned water hammer absorber, the blocking portion be tube body at the inside of threaded connection section it is radial to
Contract forms the shoulder block contradicted for piston.The necking of tube body one end squeezes to form shoulder block when manufacture, easy to process.
As another situation, in a kind of above-mentioned water hammer absorber, the blocking portion is tube body in threaded connection
The circlip contradicted for piston being embedded at the inside of section.By opening up annular groove in inboard wall of tube body and being embedded in for circlip, processing,
It installs also more convenient.
In a kind of above-mentioned water hammer absorber, the threaded connection section is the external screw thread that body open ends outer wall has
Section.
In a kind of above-mentioned water hammer absorber, the outer diameter of the external thread section is less than the outer diameter of tube body, the pipe
The outer wall that body corresponds to shoulder block forms the annular groove installed for sealing ring.The direct necking in the open end of tube body forms annular when manufacture
Slot and shoulder block, threading section, easily manufactured later, and annular groove is installed for sealing ring to guarantee the sealing after tube body connection
Property.
As another situation, in a kind of above-mentioned water hammer absorber, the threaded connection section is body open ends
The internal thread segment that inner wall has.
In a kind of above-mentioned water hammer absorber, the annular that there is the inner wall of the tube body circle to install for sealing ring is recessed
Slot, the annular groove are located at the external port of internal thread segment.Annular groove is installed for sealing ring and is positioned, and ensure that internal screw thread
Leakproofness after section connection.
In a kind of above-mentioned water hammer absorber, the outer wall of the piston is embedded with sealing element.This ensure that piston
Leakproofness between tube body avoids gas in tube body from leaking and decompression, good operating stability.
Compared with prior art, this water hammer absorber structure is simple, easily manufactured, at low cost, connection and convenient disassembly, whole
Body is good, no leak source, long service life.
Detailed description of the invention
