Abstract
The utility model relates to grease filling equipment of oil field well heads and valves, in particular to a manual oil field well head valve grease filler. According to the technical scheme, the manual oil field well head valve grease filler comprises a liquid outtake connecting tube, a left end cover, a cylinder 4, a piston, a bearing, a piston rod, a right end cover and a hand rocking handle, wherein the left end cover and the right end cover are respectively arranged at the left and right ends of the cylinder; the piston is arranged inside the cylinder; a piston rod is arranged on the piston; one end of the piston rod is connected with the piston through the bearing; the other end of the piston rod is connected with the hand rocking handle; and the left end cover is connected with the liquid outtake connecting tube. The manual oil field well head valve grease filler has the beneficial effects that the structure is simple and practical, the grease filling amount is large, the labor is saved, the sealing property is good, grease does not leak out in the grease filling process, 40 ml of grease can be filled as a hand wheel is rotated for one circle, the grease filling amount is precise, and the manual oil field well head valve grease filler can be conveniently carried over.
Description
Technical field
The utility model relates to the greasing equipment of a kind of oil field shaft mouth, valve, particularly the manual grease injection device of a kind of oil field shaft mouth valve.
Background technique
The greasing maintenance is carried out to well head, valve in the oil field at present, the general manual grease gun of buying that adopts, and greasing speed is slow, and greasing once adds lubricating grease few in the chamber, during use, catch on the other hand cavity, press back and forth on the other hand depression bar, waste time and energy, easily reveal greasing mouth joint, befouling environment.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil field shaft mouth valve manual grease injection device, and simple and practical, greasing amount is large.
Its technological scheme is: be comprised of fluid adapter, left end cap, cylinder barrel 4, piston, bearing, piston rod, right end cap, hand cranking handle, the two ends, left and right of cylinder barrel are respectively equipped with left end cap and right end cap, cylinder barrel inside is provided with piston, piston is provided with piston rod, one end of described piston rod connects piston by bearing, the other end of piston rod connects hand cranking handle, connects fluid on described left end cap and takes over.
Be provided with O type circle between above-mentioned left end cap and cylinder barrel,
Be provided with seal washer between above-mentioned piston and cylinder barrel.
The beneficial effects of the utility model are: simple and practical, greasing amount is large, and is laborsaving, good seal performance, and in the greasing process, grease can not revealed, and every rotation one circle handwheel can inject the grease of 40 milliliters, and greasing amount is accurate, and is easy to carry.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: fluid adapter 1, left end cap 2, O type circle 3, cylinder barrel 4, seal washer 5, piston 6, bearing 7, piston rod 8, right end cap 9, hand cranking handle 10.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
the utility model comprises fluid adapter 1, left end cap 2, O type circle 3, cylinder barrel 4, seal washer 5, piston 6, bearing 7, piston rod 8, right end cap 9, hand cranking handle 10, the two ends, left and right of cylinder barrel 4 are respectively equipped with left end cap 2 and right end cap 9, cylinder barrel 4 inside are provided with piston 6, piston 6 is provided with piston rod 8, one end of described piston rod 8 connects piston 6 by bearing 7, the other end of piston rod 8 connects hand cranking handle 10, connect fluid on described left end cap 2 and take over 1, be provided with O type circle 3 between described left end cap 2 and cylinder barrel 4, be provided with seal washer 5 between described piston 6 and cylinder barrel 4.
Joint 1 of the present utility model adopts taper pipe thread to be connected with left end cap 2, left end cap 2 adopts the sealing of O type circle with cylinder barrel 4, v thread connects, piston 6 water jackets are provided with two seal washers 5, the endoporus bearing 7 of packing into, the bearing inner race piston rod 8 of packing into, piston rod 8 screws into right end cap 9 internal threads, right end cap 9 is threaded with cylinder barrel 4, and piston rod 8 right-hand members are loaded onto hand cranking handle.
During use, in the inside tapered thread hole that joint 1 is screwed to that the greasing of well head or valve uses, grease injection device just has been fixed on well head or valve like this, rotates hand cranking handle piston rod rotation pushing piston and moves and can carry out greasing work; Simple and practical, greasing amount is large, and is laborsaving, good seal performance, and in the greasing process, grease can not revealed, and every rotation one circle handwheel can inject the grease of 40 milliliters, and greasing amount is accurate, and is easy to carry.
