The model utility content
Problem for the prior art existence, the purpose of this utility model is to provide a kind of single wedge type slag-off valve of uncapping with side, this slag-off valve is by arranging dismountable side cover at left valve barrel, when the flashboard needs are fastening, can carry out fastening maintenance to flashboard by side cover is pulled down, make easy to maintenance quick.
For achieving the above object, a kind of side of the utility model uncap the single wedge type slag-off valve comprise right valve barrel, be arranged on right valve barrel one side left valve barrel, mount cover valve gap on right valve barrel, be arranged on the right valve barrel upper end drive unit, be arranged on open-shut device in the right valve barrel, be arranged on the valve seat in the right valve barrel; Described open-shut device links to each other with drive unit by valve rod, and moves up and down the switching that realizes described slag-off valve under the driving of drive unit; It is characterized in that, in described left valve barrel, also be fixedly installed the fastening piece that is useful on fastening valve seat, described fastening piece comprises annular blind nut and the some double-screw bolts of tightening that is fixedly installed in the described left valve barrel, the described double-screw bolt of tightening is arranged on one to one along in the circumferential uniform some screws of jam nut, and makes described valve seat and described open-shut device close contact by tightening to tight a bolt; Also be provided with detachable side cover on the sidewall of described left valve barrel.
Further, be provided with outwardly flange on the described valve seat outer wall.
Further, also be provided with the ring-type flexible gasket in the joint of described flange and described right valve barrel.
Further, the material of described ring-type flexible gasket is graphite.
Further, described left valve barrel is fixed on the described right valve barrel by welding manner.
The utility model by employing be fixed on the open-shut device that fasteners in the left valve barrel abuts against valve seat sealing with guarantee slag-off valve without leaking.And be provided with dismountable side cover at the left valve barrel sidewall, so that slag-off valve is carried out on-line maintenance, the equipment that can not affect uses.And in right valve barrel and the joint of valve seat the Expanded graphite pad is set valve seat is combined between open-shut device more closely, realize better sealing.
