Description
Technical field:
The novel a kind of petroleum machinery of the utility model, the device of anti-bleed of especially a kind of oil well casing and survey casing pressure.
Background technology:
In the process of oil exploitation, oil well,,, both brought inconvenience to loading and unloading because the gate volume is big Yi Bian plug is housed Yi Bian gate is housed on casing head in order to prevent the sleeve pipe bleed and to survey casing pressure, had improved cost again, and was simultaneously stolen easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of device, can effectively prevent the sleeve pipe bleed, and size that can regulating sleeve gas, prevents the down-hole pump gas lock.
The purpose of this utility model is achieved in that
A kind of cover pipe plug valve system is made up of plug and spool two parts, and plug is a cylinder, top has hexagon to pull button, and the bolt hole of two band screw threads is arranged, and sidecar has screw thread outside the bottom, central axis direction has endoporus, and interior screw thread is arranged at endoporus top, and the bottom is acclive unthreaded hole; Spool is a cylinder, and outer sidecar has screw thread, matches with the interior screw thread of plug, central axis direction is drilled with the interior centre bore of top closure, and outer lower portion has tapering, the unthreaded hole matched in clearance of tapering and plug, three holes are arranged on the tapering upside cylinder, communicate with centre bore, outer upper is for pulling button.
Compared with prior art, the utility model has the advantages that: volume is little, and cost is low, and fitting operation is convenient, and is safe and reliable, is difficult for stolen simultaneously.
Description of drawings:
Fig. 1 is the structural representation of plug of the present utility model.
Fig. 2 is the structural representation of spool of the present utility model.
1 is bolt hole among the figure, and 2 pull button for hexagon, and 3 is plug, and 4 is the hole, and 5 is unthreaded hole, and 6 is spool, and 7 is centre bore, and 8 is the hole, and 9 pull button for cubic water caltrop, and 10 is screw thread, and 11 is tapering.
The specific embodiment:
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
A kind of cover pipe plug valve system is made up of plug 3 and spool 6 two parts.Plug 3 is a cylinder, and it is 35 millimeters hole that central axis direction bores a diameter, on the car in screw thread, be 22 millimeters the unthreaded hole that has the gradient 8 at diameter of the other end of plug 3 sidetracking.The car of plug 3 goes out hexagon and pulls button 2, and is pulling get on the bus two 6 millimeters the bolt hole 1 of band screw thread 10 of button 2, two 6 millimeters the bolt of screwing on, and anti-spool is stolen.
Spool 6 is 35 millimeters cylinder for diameter, outer sidecar has screw thread 10, match with the interior screw thread of plug 3, central axis direction is drilled with the interior centre bore 7 that diameter is 15 millimeters a top closure, and outer lower portion has tapering 11, load onto sealing ring, the unthreaded hole matched in clearance of tapering 11 and plug 3 is drilled with three holes on the tapering upside spool, communicate with centre bore, be used to put sleeve pipe gas, the top of spool 6 is that cubic water caltrop is pulled button on the car.
Spool 6 is installed on the plug 3, be installed on the casing head, be at ordinary times and put sleeve pipe gas valve core 6 open modes, when the sleeve pipe bleed, tighten spool 6 with clip.
