Abstract
A pressure adjusting apparatus for natural gas supplying of a natural gas boiler is formed by two paratactic pressure adjusting pipelines, an inlet pressure gage and an outlet pressure gage, wherein each pressure adjusting pipeline comprises an inlet ball valve, a pressure adjuster and an outlet ball valve; the inlet ball valve, the pressure adjuster and the outlet ball valve are in a serial connection via pipelines; the inlet pressure gage and the outlet pressure gage are respectively arranged on an air inlet pipeline in front of the pressure adjusting pipeline and an air outlet pipeline of the back of the pressure adjusting pipeline; and the air inlet pipeline and the air outlet pipeline are arranged side by side. The pressure adjusting apparatus for natural gas supplying of the natural gas boiler is advantageous in that the two paratactic pressure adjusting pipelines in the pressure adjusting apparatus operate one-on-one; when the pressure adjusters of the pressure adjusting pipelines during operation break down, the fore-and-aft ball valves can be shut down; fore-and-aft ball valves of a spare pipeline are opened, so natural gas is provided; and maintenance of the pressure adjusters are facilitated, so safe natural gas supplying of the natural gas boiler is effectively guaranteed.
Description
(1) technical field
The utility model relates to natural gas pressure regulating device, particularly a kind of regulator for natural gas boiler air feed
(2) background technique
Along with rapid development of economy, the situation day take oil as the energy is becoming tight.Boiler no longer only depends on coal, wet goods fuel, and rock gas becomes rapidly main flow fuel as the new energy of cleanliness without any pollution.But because the pressure of pipe natural gas generally all can be higher than the required pressure of boiler burning rock gas, this just need to drop to the pressure of pipe natural gas the regulator of a kind of rock gas of the required pressure of boiler burning.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, provide that a kind of flow setting is simple, compact structure, easy to use, invest little, for ease of maintenaince operation and the safe and reliable regulator for natural gas boiler air feed.
The technical solution of the utility model:
A kind of regulator for natural gas boiler air feed, formed by two pressure regulation pipelines arranged side by side and inlet pressure gauge and delivery gauge, each pressure regulation pipeline comprise inlet ball valve, pressure governor and vent ball valve and by pipeline be connected in series, inlet pressure gauge and delivery gauge are arranged at respectively the admission line before pressure regulation pipeline arranged side by side and outlet pipe below on.
The utility model has the advantages that: it is capable that a received shipment is opened in two pressure regulation pipelines employings one arranged side by side in this regulator, in the time that the pressure governor of operating pressure regulation pipeline breaks down, can close the ball valve of its front and back, then open the ball valve air feed of front and back, road for subsequent use, can conveniently carry out the maintenance of fault pressure governor, can effectively guarantee the safe way of natural gas boiler simultaneously.

Accompanying drawing is this regulator schematic diagram for natural gas boiler air feed.
In figure: 1. inlet ball valve 2. pressure governor HSR 3. vent ball valves
4. inlet pressure gauge 5. delivery gauges
(5) embodiment
Embodiment:
A kind of regulator for natural gas boiler air feed, formed by two pressure regulation pipelines arranged side by side and inlet pressure gauge 4 and delivery gauge 5, each pressure regulation pipeline comprise inlet ball valve 1, pressure governor 2 and vent ball valve 3 and by pipeline be connected in series, inlet pressure gauge 4 and delivery gauge 5 are arranged at respectively the admission line before pressure regulation pipeline arranged side by side and outlet pipe below on.
In this embodiment, the model of importing and exporting ball valve is Q41F-25C DN25; The model of pressure governor is HSR DN25PN16; Inlet pressure gauge model is Y100 0-0.6MPa, and delivery gauge model is Y100 0-10KPa.
When this regulator operation, first slowly open the inlet ball valve of the pressure regulation pipeline using, regulate the pressure of pressure governor, open the vent ball valve after pressure governor, observe manometric reading, make outlet pressure adjust to the required pressure of boiler; In the time using the pressure governor on road to break down, the ball valve of closing its front and back, slowly opens the inlet ball valve on road for subsequent use.
Claims (1)
1. the regulator for natural gas boiler air feed, it is characterized in that: formed by two pressure regulation pipelines arranged side by side and inlet pressure gauge and delivery gauge, each pressure regulation pipeline comprise inlet ball valve, pressure governor and vent ball valve and by pipeline be connected in series, inlet pressure gauge and delivery gauge are arranged at respectively the admission line before pressure regulation pipeline arranged side by side and outlet pipe below on.
