The conjuncted formula voltage regulator of filter

The utility model belongs to the technical field of gas transmission & distribution equipment, a filter integrated type voltage regulator is disclosed. Its main technical characteristics does: including having the valve body of air inlet and gas outlet, install the voltage regulator on the valve body, the trip valve is installed to the valve body lower extreme, said inlet set has the filter of built-in filtration core, and the filter is connected with the import ball valve mutually, and the gas outlet is connected with the export ball valve mutually. The utility model provides a filter integrated type voltage regulator, valve body, filter, import ball valve, export ball valve link as an organic wholely, and the valve body is in the same place with the filter for simple structure has reduced the volume. The valve body is connected with import ball valve, export ball valve respectively mutually, has saved the partly of imported ball valve, export ball valve, has reduced the interface of ball valve and valve body simultaneously, has reduced the chance of gas leakage.
