Abstract
The utility model discloses a safe releasing device used for a natural gas gate station. The safe releasing device is composed of a safety valve set, an electric ball valve, a pressure gauge and a pressure transmitter. The electric ball valve is arranged on a natural gas main pipeline, the safety valve set comprises a safety valve, an electric stop valve, a ball valve a and a ball valve b, the safety valve, the electric stop valve, the ball valve a and the ball valve b are in series connection through a pipeline, a natural gas upstream pipeline in front of the electric ball valve is connected between the ball valve a and the ball valve b through a pipeline, the pressure gauge and the pressure transmitter are respectively arranged on a natural gas downstream pipeline behind the electric ball valve and are connected with the natural gas downstream pipeline through a gauge valve a and a gauge valve b, and pressure signals of the pressure transmitter are in linkage with the electric stop valve and the electric ball valve and are connected with a power source through a guide wire. The safe releasing device has the advantages that the device achieves automatic releasing, manual operation is not required, the safety and the reliability of natural gas equipment are improved, and the device is suitable for various natural gas gate stations and large-type natural gas equipment.
Description
(1) technical field
The utility model relates to natural valve station equipment, especially for the safe diffusion device at natural valve station.
(2) background technique
The more common safety mode of diffusing in current natural valve station is to adopt choke stop evacuation valve under safety valve to connect with Flange Ball Valves, and manually opened choke stop evacuation valve is realized and being diffused.Deficiency is to need manual operation, and safety reliability is poor.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, provides a kind of and outlet pressure, electric ball valve interlocking action to realize the safe diffusion device for natural valve station of automatic relief.
The technical solution of the utility model:
A kind of safe diffusion device for natural valve station, by safety valve group, electric ball valve, pressure gauge and pressure transmitter composition, electric ball valve is arranged on rock gas main pipeline, safety valve group comprises safety valve, Electric Actuated Stop Valves, ball valve a and ball valve b also connect by pipeline, between ball valve a and ball valve b, be connected with the rock gas upstream line before electric ball valve by pipeline, on gas downstream pipeline after electric ball valve, be respectively equipped with pressure gauge and pressure transmitter and pass through Gauge Valves a, Gauge Valves b is connected with gas downstream pipeline, the pressure signal of pressure transmitter and Electric Actuated Stop Valves, electric ball valve forms interlock and is connected with power supply by wire.
Working procedure of the present utility model:
Rock gas main pipeline comes before gas, ball valve, electric ball valve and the Gauge Valves of first safety valve being connected with Electric Actuated Stop Valves are all opened, in the time passing into rock gas, rock gas can be walked around safety valve, provides pressure signal for electric ball valve and Electric Actuated Stop Valves successively through electric ball valve and pressure instrument, pressure transmitter.When normal work, close ball valve a, ball valve b and electric ball valve, realize blocking of rock gas main pipeline; In the time that overpressure appears in rock gas downstream line, Electric Actuated Stop Valves is opened automatically, realizes diffusing of safety valve, to protect user to use the safety of rock gas.
The utility model has the advantages that: this safe diffusion device is realized automatic relief, do not need manual operation, improved the safety and reliability of natural gas facility, be applicable to various natural gas door stations and large-scale natural gas equipment.
