Abstract
The utility model discloses an anti-theft pressing cap for a stuffing box of a wellhead of a pump well, which is used in various mechanical production wells. The device is composed of an outer cylinder, an inner cylinder, etc. The outer cylinder and the inner cylinder are connected by a screw thread, and an anti-theft bolt for theft protection is fixed on the top part of the utility model. The inner cylinder and a screw thread of the stuffing box of a rubber lock gate of the wellhead are connected, shape grooves on the top end of the anti-theft bolt are cooperated, and a cipher is formed so that others can not dismount a press cap of the stuffing box. The utility model can effectively prevent the illegal act that a lawbreaker steals crude oil from a well head, and protect national property and environment. The utility model is characterized in simple operation, convenient use, small investment, fast desired effect, long service life, etc.
Description
The utility model relates to the oil production equipment of petroleum industry, and particularly pumpingh well well head stuffing box anti-theft pressing cap is applicable to various mechanical oil wells.
Present oil recovery scene in petroleum industry, the stuffing box pressure cap of pumpingh well well head is the monotubular formula, with the screwed connection of rubber gate stuffing box, outward appearance top is hexahedron, use pipe wrench to carry out tightly, unload, and not having any anti-theft measure, the lawless person uses pipe wrench can arbitrarily unload loose stuffing box pressure cap, steals the crude oil that therefrom overflows.Cause that crude oil is lost, ground pollution, the property loss of country, and have a strong impact on the comprehensive regulation work in ordinary production He You district, oil field.
The purpose of this utility model is to make pumpingh well well head stuffing box anti-theft pressing cap; prevent lawless person's illegal activities; make it from the stuffing box of pumpingh well well head, not steal crude oil again; the protection national wealth; the protection environment prevents to pollute; safeguard the normal production order, help carrying out of oil district's comprehensive regulation work.
The present technique solution can reach above-mentioned purpose: pumpingh well well head stuffing box anti-theft pressing cap, to form by inner core and urceolus etc., and urceolus and inner core are by screwed connection, and be fixing antitheft at its top by anti-theft bolt, the screwed connection of inner core and well head rubber gate stuffing box.The shape groove collocation on anti-theft bolt top forms password, makes other people can not dismantle the stuffing box pressure cap.
The utility model is compared with existing stuffing box pressure cap, has the following advantages: 1, simple to operate, easy to use, and long service life.2, simple structure, easy for installation, anti-theft feature is strong.3, little, in light weight, the small investment of volume, instant effect.After using the utility model, can effectively prevent lawless person's illegal activities, protection national wealth and environment are safeguarded normal production and order of work.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of the utility model inner core.
Accompanying drawing 3 is the structural representation of the utility model urceolus.
Accompanying drawing 4 is the front view of the utility model anti-theft bolt.
But accompanying drawing 5 is overlooked and the collocation mode schematic diagram for the utility model anti-theft bolt.
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing 1-5, pumpingh well well head stuffing box anti-theft pressing cap, form by urceolus 1 and inner core 2 etc., urceolus 1 and inner core 2 are by screwed connection, fixing antitheft by anti-theft bolt 3 on its top, the screwed connection of inner core 2 and well head rubber gate stuffing box.The top of anti-theft bolt 3 have can be as T, V, P, J, Y, L or the A type groove of direction indication wherein a kind of, semi-circular plate 11 is arranged at the bottom, the quantity of anti-theft bolt 3 is 1,2 or several, utilize the arrow of every anti-theft bolt top shape groove to constitute password, this example adopts four anti-theft bolts.There is the through hole of 1 or several corresponding anti-theft bolt quantity on the top of urceolus 1, and lower inner wall has boss, on screw thread 7 is arranged.Can the design and installation handle on the external diameter of urceolus 1, handled easily, also mounting knob not, and use tool operation such as pipe wrench.One groove 9 is arranged on the internal diameter on inner core 2 tops, and the semi-circular plate 11 of every anti-theft bolt can freely rotate in this groove 9.The middle part inwall of inner core 2 has boss, and lower inner wall is provided with screw thread 10, with the screwed connection of well head rubber gate stuffing box.Corresponding groove of internal diameter boss and boss with urceolus 1 are arranged on inner core 2 external diameters, and the bottom boss has screw thread 8.This screw thread 8 is connected with the screw thread 7 of urceolus 1 inwall, and inner core 2 and urceolus 1 are linked together.When the utility model is installed, lay down former stuffing box pressure cap after, the inner core 2 usefulness pipe wrench of this device are tightened it, rotate the anti-theft bolt 3,4,5,6 on the urceolus 1 then, the semi-circular plate 11 of every bolts is screwed out the groove 9 of inner core 2 fully, install urceolus 1.After urceolus 1 and inner core 2 screwed connections on earth, make a mark on a certain anti-theft bolt limit, urceolus 2 tops, clockwise or inhour writes down the direction of arrow of every bolts top shape groove, and this four direction both had been the password of this device.Because the sensing of every bolts shape groove has " upper and lower, left and right " four kinds, the combined method of each shape groove of four bolts just has 256 kinds so.At last, every bolts is rotated to an angle, the semi-circular plate 11 of every bolts bottom is just in the groove 9 of precession inner core 2.Carry out well head stuffing box packing when work, can be according to password, the semi-circular plate 11 of several anti-theft bolts is screwed out the groove 9 of inner cores 2, password promptly is cracked, and carries urceolus 1 on then, unloads loose inner core 2 with pipe wrench, carries out filler work, promptly doses sealing ring.Dose and finish, adopt and this is installed installs identical step and get final product.
