Description

Double Valer high pressure oil gun

Technical field

The utility model relates to the technical field of equipment maintenance, and is a hand tool for filling butter between frictional running parts used for equipment maintenance. It is a tool that uses the rod principle to push the plunger, pressurize the butter, and transport the butter over a long distance through a high-pressure hose.

Background technique

When maintaining equipment, it is often necessary to add grease to the equipment. At present, the used grease gun can basically meet the needs of general equipment for adding butter, and has the characteristics of small size and convenience. Its structure is composed of oil storage cylinder, pressurized handle, etc. There is a cylinder cover at the end of the oil storage cylinder, and the oil nozzle and plunger pump are fixed on the cylinder cover. A plunger pump has a plunger inside. Move the handle up and down, butter is squeezed out from the nozzle, and the equipment is refueled. However, if the equipment that needs to be refueled is tall, it is very dangerous to operate the grease gun with both hands when refueling the equipment at high altitude. If the position that needs to be refueled is at the bottom of the equipment, the refueling operator lies on his back and operates under the equipment, which brings great inconvenience to the refueling work. The existing grease gun can only refuel the equipment at a short distance, and the grease nozzle is fixed on the cylinder cover, the direction cannot be changed, and it is operated by two hands, which is very inconvenient to use under special circumstances. Oil field pumping units need refueling and maintenance points, that is, there are many lubrication points. The location of the lubricating point has different characteristics. Moreover, there are many lubricating points at high altitude on the top of the equipment, so it is very difficult to maintain and refuel the pumping unit.

Utility model content

The purpose of this utility model is: to provide a double valve high-pressure grease gun, which overcomes the shortcomings of the existing grease gun that can only refuel at a short distance, the direction of the grease nozzle cannot be changed, and the operation of refueling the equipment is difficult by using two-handed operation. A variety of equipment, lubricating points at different locations need to be refueled, and the purpose of providing a safe and convenient grease gun for operators of high-altitude refueling of tall equipment.

The technical scheme adopted by the utility model to solve its technical problems is: it is composed of an oil storage cylinder, a plunger cylinder, a handle, etc., and the oil storage cylinder and the plunger cylinder are fixed on the base plate. A plunger is arranged in the plunger cylinder. It is characterized in that there is a rubber tube communicating between the oil storage cylinder and the plunger cylinder. The plunger in the plunger cylinder is connected with the handle, and one end of the handle is connected with the fixed frame. The lower part of the plunger cylinder has an oil inlet valve and an oil outlet valve, and the oil inlet valve is connected with the rubber hose of the oil storage cylinder. The oil outlet valve is connected with the high-pressure rubber hose. The length of the high-pressure hose is between 1-15 meters. The other end of the high-pressure hose is fixed with a connector. The connector has a hole in the center and threads at the end. The end of the connecting head is threaded to connect the oil nipple.

In order to pre-pressurize the butter stored in the oil storage tank, there is a gland on the upper part of the oil storage tank, a lead screw in the center of the gland, and a handle on the top of the lead screw. The lower part of the leading screw is connected with a pressure plate, and a coil spring is arranged between the pressure plate and the gland. The oil storage tank is filled with butter, the pressure plate is pressed on the butter, and the gland is covered. Twist the handle to pre-pressurize the butter.

The beneficial effects of the utility model are as follows: 1. Since there is a long enough high-pressure hose between the plunger cylinder and the oil nozzle, the butter pressurized by the plunger pump can be transported to a relatively long distance. 2. The high-pressure hose is a flexible material. When refueling the equipment, the nozzle can be adjusted to any direction. Therefore, the utility model double valve high-pressure grease gun can be adapted to refueling various equipment, refueling lubrication points at different positions, and provides a safe and convenient grease gun for operators who refuel tall equipment at high altitudes. The existing grease gun can only refuel at a short distance; the direction of the grease nozzle cannot be changed; and the deficiency of two-hand operation is overcome.
