The split-type ball valve comprises a valve seat, a valve rod, a valve rod shell and a valve plug, wherein two ends of the valve seat are provided with an inlet and an outlet; the inlet and the outlet pass through the inner cavity of the valve seat; the valve plug is arranged in the inner cavity of the valve seat; two end port parts of a medium path on the valve plug are respectively opposite to the inlet and the outlet on the valve seat; the upper end of the valve seat is provided with an opening passing through the inner cavity of the valve seat; the bottom of the valve rod shell is provided with a turnup which faces outwards; the turnup is provided with through holes; screws are arranged in the through holes; the valve rod shell is fixedly installed on the upper end of the valve seat via the screws; the valve rod shell is provided with a central through hole passing through the inner cavity of the valve seat; the valve rod passes through the central through hole to be fixedly connected with the valve plug; a sealing ring is arranged between the valve rod and the inner cavity wall of the valve seat. According to the split-type ball valve disclosed by the utility model, the valve seat is divided into two parts, the upper end of the valve seat is provided with the valve rod shell, the valve rod shell can be directly disassembled to repair the ball valve so as to lower the cost of the ball valve.
Description
Technical field
The utility model belongs to valve field, especially relevant with a kind of Split ball valve.
Background technique
The advantages such as it is rapid that ball valve has a switch, easy to operate, ball valve comprises valve seat, valve rod and spool etc., and spool is arranged in valve base cavity, and valve rod is fixedly connected with spool through valve seat.Existing valve seat is a monolithic construction, in the ball valve working procedure, when if the valve rod of valve base cavity, seal ring and spool need to be changed and repair, can only be keeped in repair from entrance and the opening of valve seat, now need whole ball valve is pulled down, so very inconvenient, or the ball valve directly more renewed, the waste of ball valve caused.
The model utility content
The purpose of this utility model is intended to overcome the defect of the inconvenient maintenance that existing ball valve exists, and a kind of Split ball valve easy to maintenance is provided.
For this reason, the utility model is by the following technical solutions: a kind of Split ball valve, comprise valve seat, valve rod and spool, the valve seat two ends are provided with entrance and exit, the inner chamber of entrance and exit and valve seat connects, spool is arranged in valve base cavity, medium channel two-port section on spool is relative with the entrance and exit on valve seat respectively, it is characterized in that, described ball valve also comprises the valve rod shell, the upper end of described valve seat is provided with the opening connected with valve base cavity, the bottom of valve rod shell is provided with flange outwardly, flange is provided with through hole, screw is set in through hole, the valve rod shell is fixedly installed in the valve seat upper end by described screw, the valve rod shell is provided with the center hole connected with valve base cavity, valve rod is fixedly connected with spool through central through bore, between valve rod and valve base cavity wall, seal ring is set.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristics.
Between described valve base cavity wall and spool, Gask-O-Seal is set, prevents that medium from flowing in valve base cavity, causes the corrosion of medium to the valve base cavity wall.
Use the utility model can reach following beneficial effect: the utility model is by being divided into two-part by valve seat, in the upper end of valve seat, the valve rod shell is set, while needing repairing, can directly pull down the valve rod shell, ball valve is keeped in repair, perhaps change the component in valve base cavity, thereby reduced the cost of ball valve.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
