Description
Technical Field
The invention relates to the field of gas, in particular to a gas pressure regulator breathing direction dividing device.
Background
The gas pressure regulator is commonly called a pressure reducing valve, is specially used as gas pressure regulating equipment for regulating and stabilizing pressure in a gas transmission and distribution system, and is widely applied to gas transmission and distribution engineering. The pressure regulating device has the function of automatically regulating the pressure of the gas outlet, so that the gas outlet is stabilized in a certain pressure range, the pressure value required by a user is met, and the use requirement is met.
As is well known, a gas pressure regulator is a self-regulating and self-controlling device, when the flow of an outlet changes, the pressure of the outlet changes, the balance between the pressure fed back to a main regulating diaphragm and a regulating spring changes, and the gap between a valve seat and a valve port changes correspondingly to keep the required outlet pressure. When the pressure regulator outlet pressure feedback signal is unstable, the pressure received by the main regulating membrane is unstable, so that the opening and closing of the valve port are driven to be mismatched with the feedback signal, the instability of the pressure regulator outlet signal is further caused, the surge phenomenon is caused, and the use is influenced. The breathing direction-dividing device is also called a respirator and has the functions of stabilizing the outlet pressure, preventing the occurrence of gasping and achieving the purpose of improving the use performance of the gas pressure regulator under the condition of not influencing the performance of the gas pressure regulator.
The existing respirator directly drills a hole in a workpiece to communicate with the atmosphere, which causes airflow disorder, unstable breathing and unsmooth breathing.
Disclosure of Invention
Therefore, the breathing direction dividing device of the gas pressure regulator is needed to be provided to solve the problems of airflow disorder, unstable breathing and obstruction.
The utility model provides a gas pressure regulator breathes to device, includes the breathing hole valve frame, goes up the movable plate, lower movable plate, spring, the breathing hole valve frame includes the cake, passes the axostylus axostyle at cake center perpendicularly, all be provided with two archs that extend to the outside above and below the cake, wherein every arch all uses the cake to set up as central symmetry, and above-mentioned bellied line is perpendicular with bellied line below, the breathing hole has been seted up at protruding center, the axostylus axostyle both ends are passed the movable plate respectively and are moved the movable plate down, the outside cover that lies in the movable plate on the axostylus axostyle, moves the movable plate down is equipped with the spring respectively.
Furthermore, the two ends of the shaft lever are sleeved with flat washers, and the springs are respectively positioned between the flat washers and the upper movable plate and between the flat washers and the lower movable plate.
Further, the upper movable plate is abutted against the breathing hole corresponding to the upper movable plate, and the lower movable plate is abutted against the breathing hole corresponding to the lower movable plate.
Furthermore, the periphery of the flat washer is abutted against split retainer rings, and the split retainer rings are fixed at two ends of the shaft rod through threads.
The utility model has the advantages that: when the air current from bottom to top, the air current backs up and leans on the last movable plate that leans on the breathing hole, and when the air current from top to bottom, the air current backs up and leans on the lower movable plate that leans on the breathing hole, and reciprocating cycle makes a round trip like this, and upper and lower movable plate makes a round trip in order to move, and the air current can not be disorderly, breathes stably unblocked.
