Description
Technical field
This utility model belongs to natural gas conveying equipment field, is specifically related to a kind of natural gas supply air-pressure balancing device.
Background technology
Natural gas is transported to the pipeline of urban gas center or Industry enterprise customer, also known as gas pipeline from exploitation ground or treatment plant.Utilize natural gas line to carry natural gas, be the land sole mode that carries natural gas in a large number.In world's pipeline overall length, natural gas line accounts for half.Between different pipelines or the pressure differential of pipeline and user is important parameter, the stable operation of whole system is had influence in conveying way.Due to gas supply line pipeline distance, the pressure requirements of each user side is different, causes gas supply line pressure transient.User side needs at user port, carries out pressure balance, in order to use.
Utility model content
The purpose of this utility model is that provides a kind of natural gas supply air-pressure balancing device to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of natural gas supply air-pressure balancing device, including gas pipeline, equilibrated valve, compression pump, relay, described equilibrated valve it is provided with between described gas pipeline, described equilibrated valve is provided above described compression pump, described compression pump connects described relay, described relay is connected to solenoid-operated switch, described solenoid-operated switch connects Pressure gauge, the valve body of described equilibrated valve is connected with described gas pipeline, described valve inner is provided with diaphragm, it is provided with spool on described diaphragm, described spool is provided with spring.
In said structure, described gas pipeline by natural gas transmission to described equilibrated valve, relies on the described diaphragm of described valve inner to experience the pressure differential of both sides thus the motion of spool described in automatic traction, finally balances pressure；Described Pressure gauge detects pressure differential in real time, after exceeding certain limit, signal reaches described solenoid-operated switch, then controls described compression pump and drives described equilibrated valve to carry out equilibrium air pressure.
In order to improve air pressure balance effect further, described equilibrated valve is connected with described gas pipeline by flange, and described compression pump is connected with described equilibrated valve by drive shaft, and described relay is connected by wire with described compression pump.
In order to improve air pressure balance effect further, described solenoid-operated switch is connected by holding wire with described relay, and described manometric signal output part is connected with described solenoid-operated switch holding wire.
In order to improve air pressure balance effect further, the valve body of described equilibrated valve is tightly connected with described gas pipeline, and described diaphragm is fixed on described valve inner by described spool, and described spring compression is arranged on above described spool.
Having the beneficial effects that: gone out the regulation effect of valve body balanced valve self, Pressure gauge can monitor the change of pressure reduction in real time, thus the pressure reduction of auxiliary balance system in time.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As Figure 1-Figure 2, a kind of natural gas supply air-pressure balancing device, including gas pipeline, equilibrated valve, compression pump, relay, equilibrated valve it is provided with between gas pipeline, equilibrated valve is provided above compression pump, compression pump connects relay, relay is connected to solenoid-operated switch, solenoid-operated switch connects Pressure gauge, the valve body of equilibrated valve is connected with gas pipeline, and valve inner is provided with diaphragm, and diaphragm is provided with spool, spring is installed, in order to drive the motion of spool on spool.
In said structure, gas pipeline by natural gas transmission to equilibrated valve, relies on the diaphragm of valve inner to experience the pressure differential of both sides thus the motion of automatic traction spool, finally balances pressure；Pressure gauge detects pressure differential in real time, after exceeding certain limit, signal is reached solenoid-operated switch, then controls compression pump and drives equilibrated valve to carry out equilibrium air pressure.
In order to improve air pressure balance effect further, equilibrated valve is connected with gas pipeline by flange, compression pump is connected with equilibrated valve by drive shaft, relay is connected by wire with compression pump, solenoid-operated switch is connected by holding wire with relay, and manometric signal output part is connected with solenoid-operated switch holding wire, and the valve body of equilibrated valve is tightly connected with gas pipeline, diaphragm is fixed on valve inner by spool, and spring compression is arranged on above spool.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and effect thing thereof.
