Abstract
The invention discloses a pipeline pressure control device which is installed in a natural gas well. The pipeline pressure control device comprises a scroll compressor. A frequency converter or an alternating-current servo device is connected with the scroll compressor through an electromotor. A gas inlet is formed in one end of the scroll compressor, and a gas outlet is formed in the other end of the scroll compressor. A one-way valve is installed between the gas inlet and the gas outlet. An inlet pressure transmitter is arranged at the inlet of the scroll compressor and connected with the frequency converter or the alternating-current servo device. An overpressure protection device is arranged at the outlet of the scroll compressor. By the adoption of the technical scheme, gas wells are not affected by each other even though the pressure of the gas wells differs, the yield of natural gas extraction is improved, and accidents are avoided.
Description
Technical field
The present invention is about a kind of pipe pressure controller, the pipe pressure controller that particularly a kind of natural gas well is used.
Background technology
Rock gas often has multiple gas wells in exploitation simultaneously, and the rock gas of multiple gas well extraction is imported in manifold jointly by many pipelines, is then transported to user place.But due to the pressure difference that each gas well is given vent to anger, caused at the gas well of manifold place low pressure and cannot export gas, gases at high pressure even may occur and pour in down a chimney into low-pressure gas well, not only affected the output of natural gas extraction, and easily caused danger.
Summary of the invention
The invention provides a kind of pipe pressure controller, to solve the different technical matters of each gas well pressure existing in background technology.
A kind of pipe pressure controller of the present invention, is installed in natural gas well for this reason, comprises scroll compressor, and frequency converter connects described scroll compressor by motor, and described scroll compressor one end is gas access, and one end is outlet.
Wherein, between described entrance and exit, retaining valve is installed.
Wherein, described scroll compressor porch is provided with inlet pressure transmitter, and described inlet pressure transmitter is connected with described frequency converter.
Wherein, described scroll compressor exit is provided with over-pressure safety device.
The present invention, by technique scheme, makes because of the difference of pressure, not interact between each gas well, has improved the output of natural gas extraction, avoids occurring security incident, has reached useful technique effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

Scroll compressor-1; Entrance-11; Outlet-12; Motor-2; Frequency converter-3.
Embodiment
For shape of the present invention, structure and feature can be understood better, below will enumerate preferred embodiment and be elaborated by reference to the accompanying drawings.
Pipe pressure controller of the present invention is installed on natural gas well well head, and its structure as shown in Figure 1, comprises scroll compressor 1, and frequency converter 3 connects scroll compressor 1 by motor 2.Scroll compressor 1 one end is entrance 11, and one end is outlet 12, and gas enters from this entrance 11, after this scroll compressor 1 pressurization, from this outlet 12, flows out, and reaches the effect that promotes gaseous tension in gas well.Entrance 11 and outlet are provided with retaining valve between 12, avoid gas to pour in down a chimney and shut down when wellhead pressure is high, guarantee that gas well maintains to give vent to anger.
Scroll compressor 1 entrance 11 places are provided with inlet pressure transmitter, and described inlet pressure transmitter is connected with frequency converter 3, and the pressure signal transmission of entrance 11 place's gases, to frequency converter 3, is realized to the automatic control of frequency converter 3 to pressure.When entrance 11 place's gaseous tensions are when higher, frequency converter 3 is controlled scroll compressor 1 and is exported relatively high power, and when entrance 11 place's gaseous tensions are when lower, frequency converter 3 is controlled scroll compressor 1 and exported smaller power.Scroll compressor 1 exports 12 places and is provided with over-pressure safety device, damages machine and cause danger while avoiding pressure excessive.Frequency converter 3 in above-described embodiment also can adopt Exchange Server to substitute.
The present invention, by technique scheme, makes because of the difference of pressure, not interact between each gas well, has improved the output of natural gas extraction, avoids occurring security incident, has reached useful technique effect.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it, but they all will fall within the scope of protection of the present invention in claim within the spirit limiting and scope.
Claims (4)
