Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment.
As shown in Figure 1, the utility model is a kind of boiler header pipe adapter water test unit, described pipe adapter water test unit comprises screw rod 2, O-ring seal 4, chock plug 10, tube 6 expands, described screw rod 2 is a rod shaped structure, chock plug 10 is sleeved on the screw rod 2, and O-ring seal 4 also is sleeved on the screw rod 2, and nut 3 and gland nut 9 install on the screw rod 2 from screw rod 2 two ends cover.
Described chock plug 10 is set to two, be divided into chock plug I 5, chock plug II 7, its structure is set to the diminishing cone structure of an end, the O-ring seal stationary plane 11 with the projection of O-ring seal 4 stationkeeping along 2 one weeks of screw rod is set on the described screw rod 2, the opposite side of O-ring seal 4 is set to be sleeved on the movable stationary plane 12 of O-ring seal of the circular ring structure of the sheet on the screw rod, and the movable stationary plane 12 of O-ring seal is mobilizable structure.
The diminishing cone structure of described chock plug I 5 and chock plug II 7 is corresponding to be arranged, is sleeved between chock plug I 5 on the screw rod 2 and the chock plug II 7 to have the gap.
