Abstract
The utility model relates to a valve with a pressure feedback control function. A valve body is connected to a controlled pipeline in series. The load end of the controlled pipeline is provided with a load joint. A control rod of the valve body stretches into a control mechanism. A gear is fixed to the control rod in the control mechanism. A rack meshed with the gear is fixed to one end of a piston rod. The other end of the piston rod stretches into an air cylinder in a sealed mode. The piston rod in the air cylinder is sleeved with a spring and a piston is fixed to the piston rod. The air cylinder is divided into a left cavity and a right cavity by the piston. The wall of the left cavity is provided with a left connector. The wall of the right cavity is provided with a right connector. The left connector is communicated with the load joint through a pipeline in a sealing mode. The right connector is communicated with an air source and used for setting the pressure of the controlled pipeline. The valve with the pressure feedback control function is simple in structure and convenient to use; pressure adjustment of the pipeline can be achieved without directly operating the valve, so that the safety of downstream equipment is ensured.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of valve with pressure feedback control.
Background technique
The ball valve using on pipeline at present can only be realized manual or electronic opening and closing, when upstream device breaks down, makes pressure continue to increase, and can cause downstream line seepage even to occur explosion situation.
Model utility content
In order to overcome the shortcoming of prior art, the utility model provides a kind of valve with pressure feedback control, and it is simple in structure, easy to use, without direct control valve, can realize line pressure and regulate, and ensures the safety of upstream device.
The technical scheme in the invention for solving the technical problem is: on controlled pipeline, be connected in series valve, on controlled pipeline load end, there is load connector, the controlling rod of valve stretches in control mechanism, controlling rod fixed gear in control mechanism, the tooth bar engaging with gear and one end of piston rod are fixed, the other end sealing of piston rod is stretched in cylinder, upper cover of piston rod in cylinder has spring, and fixed piston, piston will be divided into He You chamber, left chamber in cylinder, on the wall in left chamber, there is left joint, on the wall in right chamber, there is right connector, left joint communicates with load connector sealing by pipeline, right connector communicates with source of the gas, for setting the size of controlled pipeline pressure.
The utlity model has following advantages: 1), because ball valve shell and end cap are threaded connection, be convenient to like this seal ring in maintain and replace ball valve, convenient and practical; 2), due to gear being set on transmission shaft, be provided with the tooth bar engaging with gear simultaneously, drive tooth bar to do straight line motion, do circumference and rotatablely move thereby realize gear, realize the aperture of regulating valve; 3), owing to being provided with the motion of cylinder control tooth bar, the second attachment hole connects pressurized air, with acting force of the spring opposite direction, promote piston rod to left movement, thus Open valve, and the first attachment hole connects downstream line feedback pressure, consistent with spring action force direction, promotion piston rod moves right, thus throttle down, and the pressure of finally realizing valve regulates.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model valve schematic diagram.
Fig. 2 is the utility model valve control mechanism schematic diagram.
Embodiment
As Fig. 1, shown in Fig. 2, on controlled pipeline 1, be connected in series valve 3, on controlled pipeline 1 load end, there is load connector 7, the controlling rod 4 of valve 3 stretches in control mechanism 5, controlling rod 4 fixed gears 8 in control mechanism 5, the tooth bar 18 engaging with gear 8 is fixed with one end of piston rod 17, the other end sealing of piston rod 17 is stretched in cylinder 10, on piston rod 17 in cylinder 10, cover has spring 15, and fixed piston 11, piston 11 will be divided into 14He You chamber, left chamber 13 in cylinder 10, on the wall in left chamber 14, there is left joint 9, on the wall in right chamber 13, there is right connector 12, left joint 9 communicates with load connector 7 sealings by pipeline, right connector 12 communicates with source of the gas, for setting the size of controlled pipeline 1 pressure.
Described valve 3 is fixing with controlled pipeline 1 by flange 2.
Described gear 8 is fixing by flat key and described controlling rod 4.Be convenient to installation, the detachable maintaining of valve.
