| description | The utility model provides a conical surface sealed orifice valve, relating to the orifice valve in a throttling device. The conical surface sealed orifice valve comprises a tapping nozzle, a valve body, an upstream straight pipe section, a downstream straight pipe section, a valve plug and a cover board component. The conical surface sealed orifice valve is characterized in that the valve plug comprises a positioning nut arranged at the middle part of the valve body, an adjusting nut connected with threads of the positioning nut, a compression nut, a retaining nut, and a conical surface pore plate which is arranged between the adjusting nut and the valve body and is sealed by a conical surface line, wherein the direction of turning of the adjusting nut is opposite to that of the retaining nut. Therefore, the conical surface sealed orifice valve can ensure that the pore plate has reliable sealing and does not leak, guarantees the measuring accuracy, greatly increases the measuring accuracy, and brings conveni |
