Description
Technical field
The utility model relates to a kind of protective device, in particular to a kind of flap type greasing safety device.
Background technique
The maintenance of flap type valve needs regular filling seal grease and lubricating grease, now in operation, high-pressure grease pouring
The high-pressure hose union of rifle directly on there are problems to be on the greasing hole external tapping of valve, but in this way: used in valve long
After, the ball-and-seat in greasing hole is easy that stuck or spring is disconnected cannot to return seat, once the ball-and-seat in greasing hole breaks down,
It is finished in greasing, when the disassembly strong high-pressure hose of greasing, gas will spray the injures and deaths that cause personnel from greasing hole.
Summary of the invention
The purpose of the utility model is to overcome in the presence of the prior art, when the greasing hole ball-and-seat of flap type occurs
Failure and when working abnormal, the high pressure gas in flap type can be made by dismantling grease gun high-pressure hose from the greasing hole of flap type
The problem of causing casualties is sprayed from the greasing hole of flap type, is provided a kind of when the greasing hole ball-and-seat of flap type breaks down
And when working abnormal, high pressure gas can be truncated outside the greasing hole of flap type safely to dismantle grease filling machine from flap type
The flap type greasing safety device of high-pressure hose.
In order to achieve the above-mentioned object of the invention, the utility model provides following technical scheme:
A kind of flap type greasing safety device, including grease filling machine 100 and high-pressure hose 110, grease filling machine 100 pass through height
Pressure hose 110 is connected to flap type greasing hole；It further include high-pressure stop valve 200, high-pressure stop valve 200 is arranged in high-pressure hose
Between 110 and flap type greasing hole, high-pressure stop valve 200 is for being truncated or opening flap type greasing hole and high-pressure hose
110 connection.
Using this flap type greasing safety device be flap type greasing when, after for flap type greasing, first lead to
The connection between the headstock gear truncation high-pressure stop valve grease inlet of high-pressure stop valve and grease outlet is crossed, then unloads and is connected to high pressure
The high-pressure hose of shut-off valve grease inlet, the high pressure in this way when the greasing hole ball-and-seat of flap type breaks down, in flap type
Gas can also be blocked by the headstock gear in high-pressure stop valve will not spray high-pressure stop valve, therefore the high pressure gas in flap type
Staff would not be hurt, so that being embodied as staff provides the effect of security protection.
As a preferred embodiment of the present invention, high-pressure stop valve includes that the valve body of hollow cavity, valve body two sides are provided with

Specific embodiment
The utility model is described in further detail below with reference to test example and specific embodiment.But it should not be by this
The range for being interpreted as the above-mentioned theme of the utility model is only limitted to embodiment below, all to be realized based on the content of the present invention
Technology belongs to the scope of the utility model.
A kind of flap type greasing safety device as shown in Figure 1, including grease filling machine 100 and high-pressure hose 110, are also wrapped
Include high-pressure stop valve 200, the valve body 210 of high-pressure stop valve 200 including hollow cavity 212,210 two sides of valve body are provided with stream
The grease inlet 220 and grease outlet 230 that road 211 is connected with hollow cavity 212 are additionally provided with pressure relief opening 240, pressure release on valve body 210
Pressure relief device 300 is provided on mouth 240, the hollow cavity 212 of valve body 210 is additionally provided with the headstock gear 250 of opening and closing runner 211；
Pressure relief opening 240 is connected by runner 211 with 230 runner 211 of grease outlet.
Working method is, when the use of this flap type greasing safety device being 500 greasing of flap type, first uses high-pressure stop
Pressure relief device 300 on valve 200 closes the pressure relief opening 240 of high-pressure stop valve 200, and high-pressure stop valve 200 is then gone out rouge
Mouth 230 is connected on the greasing hole of flap type 500, then the grease inlet 220 of high-pressure stop valve 200 is connected to high-pressure hose 110
One end, while grease filling machine 100 being connect with the other end of high-pressure hose 110, then passes through high-pressure hose using grease filling machine 100
110, by the grease inlet 220 of grease injection high-pressure stop valve 200, are being infused by the grease of 200 grease inlet 220 of injection high-pressure stop valve
Enter after entering the hollow cavity 212 of high-pressure stop valve 200 under the pressure that rouge machine 100 applies by 220 runner 211 of grease inlet
230 runner 211 of rouge mouth and the greasing hole for entering flap type 500 from grease outlet 230, to be embodied as 500 greasing of flap type；For
After 500 greasing of flap type, 200 grease inlet of high-pressure stop valve is truncated in the headstock gear 250 for first passing through high-pressure stop valve 200
Connection between 220 and grease outlet 230, then the high-pressure hose 110 for being connected to 200 grease inlet 220 of high-pressure stop valve is unloaded, in this way
When the greasing hole ball-and-seat 501 of flap type 500 breaks down, the high pressure gas in flap type 500 also can be by high-pressure stop
The blocking of headstock gear 250 in valve 200 will not spray high-pressure stop valve 200, therefore the high pressure gas in flap type 500 would not
Staff is hurt, so that being embodied as staff provides the effect of security protection.Simultaneously as high-pressure stop valve 200 is let out
Pressure 240 runner 211 of mouth communicated with 230 runner 211 of grease outlet, it is possible to by the pressure relief device 300 of high-pressure stop valve 200 come
The pressure relief opening 240 of high-pressure stop valve 200 is opened to check whether pressure relief opening 240 has high pressure gas to release and can judge that high pressure is cut
Only whether there is high pressure gas in 200 grease outlet of valve, 230 runner 211, if having height in 200 grease outlet of high-pressure stop valve, 230 runner 211
Body of calming the anger then proves that the high pressure gas in flap type 500 is leaked by greasing hole ball-and-seat 501, therefore the greasing of flap type 500
Hole ball-and-seat 501 works abnormal；If in 200 rouge mouth runner 211 of high-pressure stop valve without high pressure gas if prove flap type 500
Interior high pressure gas does not pass through greasing hole ball-and-seat 501 and leaks, therefore the greasing hole ball-and-seat 501 of flap type 500 is working properly；
To realize the effect whether working properly of greasing hole ball-and-seat 501 for judging flap type 500.
