Abstract

The utility model relates to a dismounting-free built-in refueling device which belongs to the field of gas flow meters, and is designed to aim at that the present refueling device has a low efficiency on the flow meter, of which the gas pressure is more than 1.6 MPa. The utility model has the design point that an A oil-entering on-way valve is arranged in a fixing seat directly; the fixing seat is connected with a casing; a B oil-entering on-way valve is arranged on the casing of the gas flow meter; the B oil-entering on-way valve a push key, the A oil-entering on-way valve and an oil refueling pipe are positioned at the same axis without an external oil channel. The oil refueling pipe is installed in a machine core of the gas flow meter and is not connected with the casing. When the machine core is repaired, the machine core can be taken out without dismounting the refueling device. The utility model forms a refueling system with the gas flow meter. The utility model has the advantages of short oil-entering line and reasonable structure design. When the machine core is repaired, the refueling device does not need to be dismounted. The utility model can carry out refueling work in high voltage; thus, the utility model is convenient to operate and maintain, and the utility model has the long service life.

Description

Exempt to dismantle built-in oil-filling device

Technical field

The utility model relates to gas dosing instrument field, be a kind of can be to gas flowmeter, comprise sinking in the whirlpool and Roots in rotating component---bearing carries out oily at regular time and quantity device.

Background technique

At present, gas flowmeter both domestic and external comprises that the oil-filling device structure that sink in the whirlpool and Roots is adopted is complicated, and external oil circuit is long, and the number of times of at every turn pushing can not be implemented oiling to gas pressure greater than the flowmeter of 1.6MPa more for a long time.Simultaneously when the measurement component (movement) of flowmeter inside when breaking down, the outside oil-filling device of dismounting earlier, could take out movement and repair or replace, can make the sealability reduction of oil-filling device like this, be easy to generate oil leakage phenomenon.

Summary of the invention

The purpose of this utility model is to overcome the existing defective of original oil-filling device, provide a kind of do not have external oil channel structures, can under the state of the high pressure of 1.6～4.0MPa, implement to refuel, that needn't dismantle the flowmeter movement exempts to dismantle built-in oil-filling device.

Now in conjunction with the accompanying drawings with the following description of its feature:

As shown in Figure 1 exempt to dismantle built-in oil-filling device, this device is made up of pressing key 1, oil storage cup 2, fixed base 3, A in line check valve 4, B in line check valve 5, oil filler pipe 6; Its feature one is that A in line check valve 4 is directly installed in the fixed base 3, fixed base 3 is connected with housing 7, B in line check valve 5 is installed on the housing 7 of gas flowmeter, and with pressing key 1, A in line check valve 4, oil filler pipe 6 on same axis, need not external oil circuit (see figure 2).Its feature two is that oil filler pipe 6 is mounted in the movement 8 of gas flowmeter, is not connected with housing, when the maintenance movement, need not dismantle oil-filling device and can take out movement.

This oil-filling device and gas flowmeter constitute a fuel loading system, and the oil-feed route is short, can carry out high pressure refueling, and compression number is few, and reasonable in design during the movement maintenance, needn't be dismantled this oil-filling device, and is easy to maintenance, long service life.

Description of drawings

Fig. 1 is the structural principle schematic representation of the utility model scheme;

Fig. 2 is a local form of the present utility model schematic representation.

Sequence number and title among the figure: 1, pressing key, 2, oil storage cup, 3, fixed base, 4, the A in line check valve, 5, the B in line check valve, 6, oil filler pipe, 7, housing, 8, movement.

Embodiment

The utility model is fixed on the housing of gas flowmeter, under user mode, pass through the operation of pressing key 1, after lubricant oil in the oil storage cup 2 is pressed into A in line check valve 4 and B in line check valve 5 respectively, entering into by oil filler pipe 6 in the movement 8 of gas flowmeter, rotating component---bearing plays lubricated effect.This device also adapts to the rotating component among turbine and the Roots is carried out at regular time and quantity oily, and higher utility is arranged.

Claims

1, exempt to dismantle built-in oil-filling device, this device is made up of pressing key (1), oil storage cup (2), fixed base (3), A in line check valve (4), B in line check valve (5), oil filler pipe (6); It is characterized in that A in line check valve (4) is directly installed in the fixed base (3), fixed base (3) is connected with housing (7); B in line check valve (5) is installed on the housing (7) of gas flowmeter, and with pressing key (1), A in line check valve (4), oil filler pipe (6) on same axis.

2, according to claim 1ly exempt to dismantle built-in oil-filling device, it is characterized in that oil filler pipe (6) is mounted in the movement (8) of gas flowmeter, be connected with housing.
