Abstract
A new pressure matcher mainly comprises an actuator, a connecting piece, a driving chamber, a suction chamber, a mixing pipe and an expansion chamber. The actuator, the connecting piece, the suction chamber, the mixing pipe and the expansion chamber are connected in sequence. One end of the connecting piece is connected with the suction chamber, and the other end of the connecting piece is connected with the actuator through a flange. The driving chamber penetrates through the connecting piece, is suspended and inserted into the suction chamber and is coaxial with the mixing chamber and the expansion chamber, one end of the driving chamber close to the mixing chamber is connected with the nozzle, a valve rod is arranged in the driving chamber, one end of the valve rod is arranged on one side of the nozzle, and the other end of the valve rod is connected with the actuator through a flange. The drive steam pipe passes through the connecting piece and is connected with the drive chamber. The suction chamber is connected to the mixing chamber by a funnel. The suction chamber is provided with a suction steam pipeline interface. The biggest difference between the equipment and other pressure matchers is as follows: there is a connecting piece, the driving steam pipe passes through the connecting piece and is connected with the driving chamber. The pressure matcher shortens the length of the pressure matcher, improves the stability of the valve rod and improves the safety.

In order to solve the above problems, the present invention provides a new pressure matcher, including: actuator, connecting piece, drive chamber, suction chamber, mixing tube, expansion chamber. The actuator, the connecting piece, the suction chamber, the mixing pipe and the expansion chamber are connected in sequence. One end of the connecting piece is connected with the suction chamber, and the other end of the connecting piece is connected with the actuator through a flange. The driving chamber passes through the connecting piece, is suspended and inserted into the suction chamber and is coaxial with the mixing chamber and the expansion chamber, one end of the driving chamber close to the mixing chamber is provided with a nozzle, a valve rod is arranged in the driving chamber, one end of the valve rod is arranged on one side of the nozzle, and the other end of the valve rod is connected with an actuator through a flange. The drive steam pipe passes through the connecting piece and is connected with the drive chamber. The suction chamber is connected to the mixing chamber by a funnel. The suction chamber is provided with a suction steam pipeline interface. The biggest difference between the equipment and other pressure matchers is as follows: there is a connecting piece, the driving steam pipe passes through the connecting piece and is connected with the driving chamber.
Preferably, the flange between the connecting piece and the actuator is replaced by a high-pressure self-tightening sealing structure;
preferably, the flange and the connecting piece are of an integrated structure;
preferably, a valve rod supporting disk and a valve rod guide are arranged in the driving chamber, and the supporting disk is fixed on the valve rod preferentially;
preferably, the pressure matching combination device and the control system form the pressure matching combination device and the intelligent combination pressure matching device as the body of the pressure matching combination device;
preferably, the driving steam inlet main pipe, the steam suction inlet main pipe, the driving steam bypass, the steam suction bypass and the outlet steam pipeline are provided with devices such as a heating device, a pressure stabilizing device, a draining device, a filtering device, a desuperheater and the like;
preferably, a check valve is arranged on the suction steam pipe;
preferably, a safety valve is arranged on the mixed steam outlet pipe.
By adopting the technical scheme, the invention has the beneficial effects that:
(1) the length of the pressure matcher is shortened, and the stability of the valve rod is improved;
(2) the connecting piece replaces flange connection, and the sealing performance and the safety are improved.
