Abstract
The utility model relates to an one way gas pressure regulating box that can overhaul on line, the power distribution box comprises a box body, for the gas import below the box, the inlet pipe that connects the gas import penetrates and connects gradually the inlet pressure table that constitutes the pressure regulating pipeline behind the box, a filte, the voltage regulator, diffuse the mouth, pipeline safety valve and outlet pressure gauge, the export pipeline of pressure regulating pipeline wears out the box and is connected with gas exports, bypass parallelly connected with the pressure regulating pipeline of installation between inlet pipe and export pipeline, this bypass further include with the imported valve of inlet pipe rigid coupling and with the outlet valve of export pipeline rigid coupling, be connected by inlet flange between imported valve and outlet valve, reserve filter, reserve voltage regulator and outlet(discharge) flange pipeline concatenate the replacement section of constitution. The utility model discloses simple structure, safe and reliable, easy to carry out, easy maintenance especially can overhaul on line.
Description
Technical field
The utility model belongs to natural gas pressure regulating equipment technical field, specifically a kind of can the single channel fuel gas pressure-regulating box of on-bne repair.
Background technique
Pressure-regulating box is gas transmission and distribution link very important equipment, and there are standard and the manufacturing standard of specification in country to this.Fuel gas pressure-regulating box in the past has single channel and two-way (multichannel), and single channel cannot on-line maintenance, runs into fault and only stops the supple of gas or steam and keep in repair; Two-way (multichannel) can on-bne repair, but cost is high, brings application and Cost Problems so just to the popularization and application of pressure-regulating box.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and propose a kind of can the single channel fuel gas pressure-regulating box of on-bne repair.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of can the single channel fuel gas pressure-regulating box of on-bne repair, comprise casing, it is fuel gas inlet below the lower wall of casing, connect the inlet pressure gauge connecting and composing pressure regulation pipeline after the inlet pipe of fuel gas inlet penetrates casing successively, filter, pressure governor, diffusion mouth, Piping Safety Valves and delivery gauge, the lower wall that the outlet conduit of pressure regulation pipeline passes casing is connected with gas outlet, install between inlet pipe with outlet conduit one in parallel with pressure regulation pipeline for detecting time bypass, this bypass comprises the inlet valve affixed with inlet pipe and the outlet valve affixed with outlet conduit further, be connected between inlet valve with outlet valve by suction flange, reserve filter, the replacement section that pressure governor for subsequent use and outlet(discharge) flange pipeline serial connection are formed.
And, after pressure regulation pipeline has overhauled, be describedly connected in series by suction flange, reserve filter, pressure governor for subsequent use and outlet(discharge) flange pipeline the replacement Duan Youyi root straight length that forms and replaced.
Advantage of the present utility model and good effect are:
The utility model structure is simple, safe and reliable, easy to implement, easy to maintenance, particularly can on-bne repair, and the popularization and application for natural gas pressure regulating case provides better product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of can the single channel fuel gas pressure-regulating box of on-bne repair, as shown in Figure 1, comprise casing 2, it is fuel gas inlet 1 below the lower wall of casing, connect after the inlet pipe 17 of fuel gas inlet penetrates casing and be connected with the inlet pressure gauge 3 forming pressure regulation pipeline in turn, filter 7, pressure governor 8, diffusion mouth 10, Piping Safety Valves 11 and delivery gauge 14, the lower wall that the outlet conduit 15 of pressure regulation pipeline passes casing is connected with gas outlet 16, innovative point of the present utility model is, install between inlet pipe with outlet conduit one in parallel with pressure regulation pipeline for detecting time bypass, this bypass comprises the inlet valve 4 affixed with inlet pipe and the outlet valve 12 affixed with outlet conduit further, be connected by suction flange 5 between inlet valve with outlet valve, reserve filter 6, the replacement section that pressure governor 9 for subsequent use and outlet(discharge) flange 13 pipeline serial connection are formed.
In concrete enforcement of the present utility model, after pressure regulation pipeline has overhauled, describedly be connected in series by suction flange, reserve filter, pressure governor for subsequent use and outlet(discharge) flange pipeline the replacement Duan Youyi root straight length that forms and replace, the replacement section of replacing is for the maintenance of other single channel fuel gas pressure-regulating boxes.
Embodiment
In this embodiment, the model of described pressure governor and pressure governor for subsequent use is FisherHSRDN25; The model of described inlet valve and inlet valve is Q41F-16DN25; The model of described filter and reserve filter is GL41H-16DN25, and the model of safety valve is RAF-15.Practice shows, effect is good.
Claims (2)
1. one kind can the single channel fuel gas pressure-regulating box of on-bne repair, comprise casing, it is fuel gas inlet below the lower wall of casing, connect the inlet pressure gauge connecting and composing pressure regulation pipeline after the inlet pipe of fuel gas inlet penetrates casing successively, filter, pressure governor, diffusion mouth, Piping Safety Valves and delivery gauge, the lower wall that the outlet conduit of pressure regulation pipeline passes casing is connected with gas outlet, it is characterized in that: install between inlet pipe with outlet conduit one in parallel with pressure regulation pipeline for detecting time bypass, this bypass comprises the inlet valve affixed with inlet pipe and the outlet valve affixed with outlet conduit further, be connected between inlet valve with outlet valve by suction flange, reserve filter, the replacement section that pressure governor for subsequent use and outlet(discharge) flange pipeline serial connection are formed.
