Working principle of the present utility model is as follows:
1, the orifice plate step is proposed:
1.1, turn on equilibrium valve, make down the medium of body cavity enter the upper valve body inner chamber, upper and lower body cavity pressure balance;
1.2, rotate the slide carriage axle and open guiding valve, upper and lower valve body is communicated with;
1.3, rotate the guide plate axle, guide plate is upwards mentioned together with the orifice plate that is contained in the inside, guide plate enters into upper valve body and gear shaft engagement, the turning gear wheel shaft is mentioned the upper valve body inner chamber with orifice plate then;
1.4, close equilibrium valve, disconnect upper and lower body cavity medium.Counter-rotation slide carriage axle is closed guiding valve, cuts off upper and lower valve channel;
1.5, drive atmospheric valve slowly, drain upper valve body inner chamber medium;
1.6, lay down valve gap;
1.7, the turning gear wheel shaft, guide plate is risen to the upper valve body top together with the orifice plate that is contained in the inside, take out orifice plate and can change.
2, the orifice plate of packing into:
2.1, orifice plate is packed in the guide plate earlier, the upper valve body inner chamber of packing into makes the gear engagement of the rack and pinion axle on the guide plate;
2.2, the turning gear wheel shaft, make guide plate together be contained in the inside orifice plate enter the upper valve body inner chamber, till loading onto valve gap;
2.3, load onto valve gap;
2.4, close atmospheric valve, prevent that medium flows out outside the valve body in the valve;
2.5, open equilibrium valve, make down the medium of body cavity enter the upper valve body inner chamber, upper and lower body cavity pressure balance;
2.6, rotate the slide carriage axle, open guiding valve;
2.7, rotate the gear shaft of upper valve body, make guide plate descending together with the orifice plate that is contained in the inside, the gear engagement on the guide plate axle in the tooth bar on guide plate and the following valve body is rotated the guide plate axle, and guide plate is delivered to down working position in the valve body together with the orifice plate inside being contained in;
2.8, close equilibrium valve;
2.9, rotate the slide carriage axle, close guiding valve;
2.10, inject seal gease from grease pouring valve.
The utility model compared with prior art has following advantage:
1), can realize not stopping medium transport, maintenance and inspection and replacing orifice plate fast;
2), sealing is reliable, operate easyly rapidly, extracting at every turn or change orifice plate only need 3～5 minute;
3), need not set up bypass, do not reduce floor space, simplified technological process.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
