Abstract
The utility model relates to a environment-friendly code anti-theft foreshaft cap, which belongs to the oil-well foreshaft sealing and blocking device. The sealing head is fixedly connected with the connector, the main body is rotatingly connected with two to eight code pins, the lower end of the code pin is fixedly connected with a lock pin, the lock pin is rotatingly connected with the concave lock groove on the sealing head, the lock pin is provided with an inward-concave arc-shaped slot, the arc-shaped slot is the same with that on the upper part of the sealing head, the circumference of the code pin of the main body is provided with a code calibration, the top of the code pin is provided with a code disc calibration line. The utility model has the advantages of innovative structure and design, realizes the sealing and blocking of the foreshaft and performs the opening and closing with the code, which is safe, environment friendly and convenient to operate.
Description
Technical field
The utility model belongs to the well mouth of oil well plugging device.
Background technology
At present, the oil field is used for the wellhead cap that the shutoff operation of well mouth of oil well uses and mostly is the plain edition wellhead cap, and is bad to the sealing function of well head, anti-theft feature is not strong, cause wellhead cap often to lose after, crude oil is also often stolen, sewage and crude oil often flow into the field, cause environment pollution.
Summary of the invention
The utility model provides a kind of environment-friendly type cipher anti theft wellhead cap, and to solve present plain edition wellhead cap, anti-theft feature is not strong, the problem that sealing function is bad.The technical scheme that the utility model is taked is: plug is fixedlyed connected with connector, 2～8 password pins are rotationally connected on the main body, the fixedly connected lock pin in the lower end of this password pin, indent locked groove on this lock pin and the plug is rotationally connected, the circular arc cutaway that indent is arranged on this lock pin, this circular arc cutaway is consistent with the circular arc on plug top, and the password pinhole periphery of this main body is carved with password scale, and the combination disk groove is arranged at this password pin top; In plug inside through hole is arranged, fixedly connected valve seat in this through hole has valve ball in this valve seat, and there is spring this valve ball below.
During use, dress is during wellhead cap, successively with the combination disk groove of each password pin to given number of division on the accurate dial of main body, at this moment both hands can have been held the wellhead cap assembly, do not stir combination disk after the wellhead cap assembly unloads; Plug is screwed on the well head with instrument, again the wellhead cap assembly is worn on the main body, and firmly depresses, it is put in place, arbitrarily stir each combination disk, promptly finished installation exercise with screwdriver.Unload wellhead cap, rotate combination disk respectively, make groove aim at given number of division on the dial, can with the hands hold the wellhead cap assembly with screwdriver.After the wellhead cap assembly unloads, can exit, the work of draining the oil, at first vent valve is inserted on the valve, the vent valve that slowly turns clockwise then can be exitted after vent valve backs down valve, be drained the oil.The venting, drain the oil finish after, unload the wellhead cap seat with box spanner and can carry out other operations.
The utility model advantage is: novel structure, design ingeniously, and solved present plain edition wellhead cap, anti-theft feature is not strong, the problem that sealing function is bad.Can realize shutoff, utilize password to open well head, safety, environmental protection, easy to operate.
