The invention provides a diaphragm type pressure regulator which enables an adjusting valve and a stopping valve to be assembled easily on an entrance access of a gas flow path, and can prevent the bad opening of the adjusting valve or the bad closing of the stopping valve. A diaphragm used for dividing and forming a pressure regulating chamber and an atmospheric pressure chamber is arranged in a regulator main body, a connecting body is arranged in the center of the diaphragm, and a permanent magnet overcoming a deviation spring on the lower surface of the connecting body and overcoming the acting force of the deviation spring to be absorbed on the connecting body to thereby be contacted and separated with the connecting body up and down is equipped with a hanging body. The adjusting valve and the stopping valve are arranged on the entrance access independently and respectively. The adjusting valve is connected with a work rod working along with the lifting of the hanging body, and the stopping valve is maintained at the opening position under the acting force of a resetting spring, is applied a flow pressure of a gas formed by the entrance access when the stopping valve is opened fully, and overcomes the acting force of the resetting spring to be closed. |
