Description
Technical Field
The utility model relates to an engineering machine tool equipment technical field, concretely relates to quick inflation valve of rock drill energy storage ware.
Background
A hand-held rock drill is a drilling tool, which can use hydraulic power source to provide power to drill rock and drill hole on rock. The energy storage device is an important component, can store energy when the system energy is large, and release energy when the system energy is small, so as to adjust the balance of the whole hydraulic power, further effectively keep the stability of the rock drilling speed, and achieve the effect of energy conservation. The energy charging device of the existing rock drill energy accumulator in the market adopts an air charging nozzle, air is charged through a needle type air charging valve, the air charging is slow due to the fact that an air inlet of the air charging nozzle is extremely small, and the device is complex in structure and prone to air leakage and damage of the air charging nozzle.
Disclosure of Invention
To the problem, an object of the utility model is to provide a quick gas charging valve of rock drill energy storage ware replaces traditional needle type gas charging valve with gas charging bolt and aerifys, aerifys soon, simple structure, not fragile.
In order to achieve the purpose, the utility model adopts the technical proposal that: a rock drill energy accumulator quick charging valve comprises an air bag arranged in a shell, wherein a gland is arranged at the top of the shell and is connected with the shell through threads, and the air bag is sealed to form a nitrogen chamber; a cylindrical inflation inlet communicated with the nitrogen chamber is formed in the center of the gland, an inflation bolt is inserted into the inflation inlet, an inflation channel is arranged in the inflation bolt, a steel sealing gasket is arranged outside an opening in the top of the inflation channel, the sealing gasket is good in elasticity and not easy to damage, and the sealing gasket is used for controlling the inflation channel to be opened or closed; and a sealing nut is arranged outside the inflation inlet.
Furthermore, a sealing ring is arranged at the bottom of the sealing nut.
The inflation channel is arranged at the axis of the inflation bolt, and the top of the inflation channel extends outwards horizontally and is communicated with the outside.
Compared with the prior art, the beneficial effects of the utility model are that: the inflation bolt and the sealing gasket are matched to replace a traditional needle type inflation valve for inflation, the inflation speed is high, the structure is simple, the operation is easy, the damage is not easy, the maintenance cost is almost avoided, and the economic benefit of the product is greatly improved.

fig. 4 is a schematic view showing the direction of airflow movement after the completion of the inflation of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-4, the rock drill energy accumulator quick inflation valve comprises an air bag 2 arranged in a shell 1, a gland 3 is arranged at the top of the shell and connected with the shell through threads, and the air bag is sealed to form a nitrogen chamber 4. The center of the gland 3 is provided with a cylindrical inflation inlet 5 communicated with the nitrogen chamber, an inflation bolt 6 is inserted into the inflation inlet, an inflation channel 7 is arranged in the inflation bolt, a steel sealing gasket 8 is arranged outside an opening at the top of the inflation channel, the sealing gasket is good in elasticity and not easy to damage, and the sealing gasket is used for controlling the inflation channel to be opened or closed. And a sealing nut 9 is arranged outside the inflation inlet.
In order to enhance the sealing effect, the bottom of the sealing nut is provided with a sealing ring 10.
The inflation channel is arranged at the axis of the inflation bolt, and the top of the inflation channel extends outwards horizontally and is communicated with the outside.
As shown in figure 2, when filling nitrogen, firstly the sealing nut 9 is screwed off, then the gas-filled bolt 6 is unscrewed for 1/4 of a circle, so that the sealing gasket 8 has a space for moving up and down, and then a joint 11 is arranged on the gas-filled port of the gland. The arrow direction in fig. 3 and 4 shows the moving direction of the air flow, the specific process is that the nitrogen cylinder and the connector are connected by the nitrogen charging tool 12 to form an air passage, when charging nitrogen, the valve on the nitrogen cylinder is opened first, the switch valve of the nitrogen charging tool is pressed down to connect the whole air passage, as shown in fig. 3, at this moment, the air pressure exists in the sealed area of the charging port, the air pressure pushes the sealing gasket downwards to make the sealing gasket tightly attached to the upper end face of the gland, the top opening of the charging channel is opened, and the air flow enters the nitrogen chamber. After the nitrogen filling is finished, the valve of the nitrogen cylinder is closed, the nitrogen filling tool is taken down, the connector is disassembled, as shown in figure 4, under the action of the pressure in the nitrogen chamber, the air flow pushes the sealing gasket upwards to seal the top opening of the inflation channel to prevent the air from leaking, then the inflation bolt is screwed down, and the sealing nut is mounted.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention is included in the protection scope of the present invention.
