In use, step 1, as shown in Figure 1, user is when carrying out petroleum pipeline laying, due to often containing inside petroleum
More solid impurity, thus during transportation, impurity can constantly corrode valve internal, so that valve part aged deterioration, from
And must not timing valve arrangement is overhauled, so that valve is worked normally, however traditional valve, inside are all made of spiral shell
The connection type of bolt the problem of being easy to appear corrosion, can not so as to cause internal part after being immersed in petroleum the time too long
It removing in time, and installation and removal are all more troublesome, a kind of oil equipment of this money can be used with just tearing valve open in user thus,
It is above-mentioned to solve the problems, such as；
Step 2, as shown in figures 2-6, user is when carrying out service work to valve, the pressure mistake inside valve body 1 in order to prevent
Greatly, so that user dismantles, valve deck 2 is relatively elaborate, and user can first screw off pressure release nut 203 this moment, this moment valve body
Pressure inside 1 will be discharged via relief fittings 202 and pressure release through-hole 201, so that 1 internal pressure of valve body reduces, this moment
User can use spanner to remove valve deck 2 from 1 top of valve body, filtering dress after valve deck 2 removes, inside valve body 1
Set 3 and quick access device 4 will be fallen together with valve deck 2, this moment by quick access device 4 from 2 top second of valve deck sealing card slot 204 from
It takes out, filter cylinder gasket 301 and filter cylinder support ring 302 is removed from 303 top of tubulose filter cylinder, then push down on quick access this moment
Housing 401, second boss 405 can squeeze compressed spring 408 this moment, and close to first boss 404, this moment quick access tapered sleeve 403
It can be moved downward together with quick access housing 401, and limiting ball 407 from contacting with cylindroid 410 is excessively tapered surface 409,
Limit ball 407 loses pressure this moment, so that spherical groove 406 skids off, this moment can smoothly remove tubulose filter cylinder 303,
Then all components are cleaned, checks whether all components the case where excessive wear occur, to be replaced；
Then step 3 repeats step 2 as shown in figures 1 to 6 again, tubulose filter cylinder 303 is packed into inside quick access device 4, will be filtered
Cylinder gasket 301 and filter cylinder support ring 302 are fixed, then will be tightened by bolts between valve deck 2 and valve body 1, this moment in order to anti-
Only 1 inner air of valve body is excessive, and the venting plug 105 of 1 upper air vent 104 of valve body is opened, then full to lead to inside valve body 1
After petroleum, then venting plug 105 to be locked, prevents petroleum excessive from exhaust outlet 104, integrated operation is simple, and it is time saving and energy saving, to make
User saves a large amount of activity durations.
Control mode of the invention is automatically controlled by controller, the skill that the control circuit of controller passes through this field
Art personnel's simple programming can be realized, and belong to the common knowledge of this field, and the present invention is mainly used to protect mechanical setting, institute
