By adopting technique scheme, magnet is set for spheroid is installed on the body of rod, be convenient to spheroid dismounting, simple to operate in ensureing constant intensity, secondly, the fitting surface of arc prevents that spheroid is at work accurately to the heart, can not promote to cause spheroid skew because of extraneous resistance.
The utility model is further set to: described black box comprises the seal ring that is sheathed on the body of rod, and described seal ring is the concavity suitable with gas pipeline side face towards the end face of spheroid, between described head and seal ring, has been installed with spring.
By adopting technique scheme, the seal ring of concavity is fully fitted and is sealed with gas pipeline side face, and spring ensures that both have sufficient adhesive force, can delamination.
The utility model is further set to: the position that described body of rod outer circumferential face is positioned in the middle of screw thread is provided with slippage slot, described seal ring is flush-mounted in slippage slot and body of rod axial slip relatively, and described seal ring is provided with the screens groove suitable with screw thread side face on the end face of spheroid.
By adopting technique scheme, the setting of slippage slot adds the sphere of activities of big sealing ring, spheroid adjustable extent is increased, when spheroid bounces back augmented flow together with the body of rod, seal ring can continue laminating gas pipeline along the downward slippage of slippage slot, ensures sealing function, also set up screens groove, also further increase sealability playing in spacing to seal ring, the space of the screw thread surrounding of can fitting, also further increases regulation range.
The utility model is further set to: the position that described seal ring is corresponding with spring is provided with the mounting groove two for mounting spring, in described mounting groove two, is filled with the adhesive for adhesion spring.
By adopting technique scheme, the mounting groove two that is filled with adhesive is fully fixing with spring, is difficult for departing from, and spring can be synchronized with the movement with seal ring, ensures to press effect.
The utility model is further set to: the position that described head is corresponding with spring is provided with the regulating tank of adjusting angle of swing for seal ring.
By adopting technique scheme, regulating tank be set to spring and seal ring leads simultaneously, in the time that the seal ring face of spill cannot be corresponding with gas pipeline, just can reach by torsional spring the object of adjustment, simple to operation.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
