Abstract
The utility model relates to an electric/pneumatic controller used for a fuel gas pressure control system, which is characterized by including a bracket, a pressure regulator, a buffer tank, a safety bleeding valve, a pressure gauge, signal pipes and an electric/pneumatic converter. The buffer tank fixedly connected on the bracket is connected with the pressure regulator and the electric/pneumatic converter fixedly connected on the bracket through the signal pipes. The electric/pneumatic controller has benefits that the power of the controller comes from compressed gas, the gas source of the controller can adopt bottled (canned) compressed gas or non-corrosive compressed gas conveyed by a pipeline, the natural gas is included, an outlet of the controller is connected with a spring cavity of a self-power pressure regulating valve or a cut-off valve, and the pressure at the outlet is controlled by a remote electronic signal, therefore, the remote pressure setting and control can be realized.
Description
Technical field
The utility model belongs to the control gear of gaseous-pressure control system, relates in particular to a kind of electric/pneumatic controller that is used for the gaseous-pressure control system.
Background technique
In fuel gas transportation pipeline and relevant device, voltage adjusting device is a core component, and for self-powering type pressure regulator valve and cut-off valve, each usually its setting value that changes can only be operated very loaded down with trivial details and relative risk by on-site manual.Some occasions is used electric control valve, but the electric control valve low-response, power consumption is big, maintenance cost is high.Combustion gas is carried and is demanded developing a kind of accurately energy-conservation again controlling method and equipment of controlling urgently.
The model utility content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology; And a kind of electric/pneumatic controller that is used for the gaseous-pressure control system is provided; The nothing corrosion pressurized gas conduct that utilizes canned pressurized gas or line transportation is as driving force; Accurately control the delivery pressure of electric/pneumatic controller through the long distance electric signal, carry out long-range setting and control pressure regulator valve or cut-off valve.
The utility model is for realizing above-mentioned purpose; Adopt following technological scheme: a kind of electric/pneumatic controller that is used for the gaseous-pressure control system; It is characterized in that: comprise support, pressure governor, knock out drum, Safety relief valve, pressure gauge, signal tube and electric/pneumatic transducer, the said knock out drum that is fixed on the support is connected with pressure governor and electric/pneumatic transducer on being fixed in support through signal tube respectively.
Affixed pressure gauge and Safety relief valve on the said knock out drum.
Beneficial effect: the power of this controller is pressurized gas; The controller source of the gas can adopt bottle (jar) dress pressurized gas; Also can use the non-aggressive pressurized gas of line transportation, comprise rock gas, the controller outlet links to each other with the spring chamber of self-powering type pressure regulator valve or cut-off valve; By electronic remote SC sigmal control outlet pressure, thereby realize that remote pressure is set and control.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the systematic schematic diagram of the utility model.
Among the figure: 1. pressure governor, 2. knock out drum, 3. cutting ferrule joint, 4. pressure gauge, 5. signal tube, 6. Safety relief valve, 7. electric/pneumatic transducer, 8. support.
Embodiment
Embodiment below in conjunction with accompanying drawing and preferred embodiment detailed description the utility model.As shown in the figure; See accompanying drawing for details; A kind of electric/pneumatic controller that is used for the gaseous-pressure control system; Comprise support 8, pressure governor 1, knock out drum 2, Safety relief valve 6, pressure gauge 4, signal tube 5 and electric/pneumatic transducer 7, the said knock out drum that is fixed on the support is connected with pressure governor and electric/pneumatic transducer on being fixed in support through signal tube respectively.Signal tube is connected with knock out drum, pressure governor and electric/pneumatic transducer through cutting ferrule joint 3.Affixed pressure gauge and Safety relief valve on the said knock out drum.
Working principle:
The controller source of the gas can adopt bottle (jar) dress pressurized gas; Also can use the non-aggressive pressurized gas of line transportation; Comprise rock gas; The controller outlet links to each other with the spring chamber of self-powering type pressure regulator valve or cut-off valve, by electronic remote SC sigmal control outlet pressure, thereby realizes that remote pressure is set and control.Interface is 1. for driving gas source interface; Use pressure governor to be used for reducing pressure or voltage stabilizing after inserting source of the gas to driving air pressure; After knock out drum is installed in pressure governor, be used for storing a certain amount of gas, guarantee to get into the pressure stability and the stability of flow of electric/pneumatic transducer temporarily.The electric/pneumatic transducer is used for being converted into the electronic remote control signal gas pressure of corresponding ratio, 2. exports pneumatic control signal through interface, and 2. interface is connected with pressure regulator valve or cut-off valve.Wherein setting pressure table and Safety relief valve on the knock out drum are used to show the inlet pressure of electric/pneumatic transducer and the safety of protection electric/pneumatic transducer.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technological scheme of the utility model.
Claims (2)
