Description

A kind of combustion gas building regulation boxes
Technical field
The utility model relates to pressure-regulating box, specifically a kind of combustion gas building regulation boxes.
Background technique
Along with the continuous expansion of social demand, if do not adopt fuel gas pressure-regulating box in the middle of life, then can only adopt region pressure regulating cabinet air feed, but scope of stopping the supple of gas or steam when this kind of method breaks down is large, is difficult to replacing, can only on-line maintenance; And air feed is difficult to for the user area pressure regulating cabinet that the gas consumptions such as functions for residential building, villa, back yard industry are very little or air feed cost is very high.Therefore the utility model provides a kind of fuel gas pressure-regulating box at this, solves the problem.
Model utility content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, proposes a kind of combustion gas building regulation boxes, pressure governor is provided with in this combustion gas building regulation boxes, outlet pressure is stablized, and is furnished with superelevation, super-low voltage cut-out resetting structure, reset more convenient; Arrange the curved mouth ball valve of venting, avoid the excessive accident that causes of outlet pressure to occur, increase reliability and the Security of equipment, improve the working life of equipment, easy to maintenance, dismounting is simple, reduces costs.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: a kind of combustion gas building regulation boxes, comprise the rectangular box vertically arranged, casing is built-in be provided with a pressure governor with a filter and the input port of the output port of filter and pressure governor in the horizontal direction conducting be connected, the lower end input port of filter vertically connects suction flange by an inlet ball valve and described suction flange passes casing straight down, the lower end output port of pressure governor vertically successively by a curved mouth ball valve of venting and a vent ball valve connection outlet flange and outlet(discharge) flange vertically through casing, wherein:
Inlet ball valve screw-thread fit respectively and between filter and suction flange, exits between curved mouth ball valve and pressure governor, exits between curved mouth ball valve and vent ball valve, is screw-thread fit between vent ball valve and outlet(discharge) flange.
Like this, in this combustion gas building regulation boxes, be provided with pressure governor, outlet pressure is stablized, and be furnished with superelevation, super-low voltage cut-out resetting structure, reset more convenient; Arrange the curved mouth ball valve of venting, avoid the excessive accident that causes of outlet pressure to occur, increase reliability and the Security of equipment, improve the working life of equipment, easy to maintenance, dismounting is simple, reduces costs.
The technological scheme that the utility model limits further is:
Aforesaid combustion gas building regulation boxes, also inlet pressure gauge is provided with between inlet ball valve and filter, exit between curved mouth ball valve and vent ball valve and be provided with delivery gauge, filter adopts stainless steel steel wire filter core, like this, by arranging the force value in the effective monitored pipeline of pressure gauge energy, stainless steel steel wire filter core is adopted, can prevent filter core from getting rusty, increase the working life of filter.
The beneficial effects of the utility model are: pass through the technical solution of the utility model, be arranged on rational height and position, facilitate operative, easy to maintenance, increase work efficiency, in this combustion gas building regulation boxes, be provided with pressure governor, outlet pressure is stablized, and be furnished with superelevation, super-low voltage cuts off resetting structure, reset more convenient; The curved mouth ball valve of venting is set, the excessive accident that causes of outlet pressure is avoided to occur, the reliability of increase equipment and Security, the working life of raising equipment, easy to maintenance, dismounting is simple, reduce costs, and exit curved mouth ball valve, filter and pressure governor all belong to prior art, directly can buy finished product, maintenance and replacing are conveniently.
Accompanying drawing explanation
The structure sectional view of the combustion gas building regulation boxes of Fig. 1 designed by the utility model;
Wherein: 1-casing, 2-suction flange, 3-outlet(discharge) flange, 4-inlet ball valve, 5-inlet pressure gauge, 6-filter, 7-pressure governor, 8-exits curved mouth ball valve, 9-delivery gauge, 10-vent ball valve.
Embodiment
Below the utility model is by reference to the accompanying drawings described in further detail:
embodiment 1
As shown in Figure 1, a kind of combustion gas building regulation boxes that the present embodiment provides, comprise the rectangular box 1 vertically arranged, casing 1 is built-in be provided with a pressure governor 7 with a filter 6 and the input port of the output port of filter 6 and pressure governor 7 in the horizontal direction conducting be connected, the lower end input port of filter 6 vertically connects suction flange 2 by an inlet ball valve 4 and suction flange 2 passes casing 1 straight down, the lower end output port of pressure governor 7 vertically successively by a curved mouth ball valve 8 of venting and a vent ball valve 10 connection outlet flange 3 and outlet(discharge) flange 3 vertically through casing 1, wherein:
Inlet ball valve 4 screw-thread fit respectively and between filter 6 and suction flange 2, exit between curved mouth ball valve 8 and pressure governor 7, exit between curved mouth ball valve 8 and vent ball valve 10, between vent ball valve 10 and outlet(discharge) flange 3, be screw-thread fit, inlet pressure gauge 5 is also provided with between inlet ball valve 4 and filter 6, exit between curved mouth ball valve 8 and vent ball valve 10 and be provided with delivery gauge 9, filter 6 adopts stainless steel steel wire filter core.
The working procedure of the present embodiment: pressure-regulating box is accessed in pipe-line system by suction flange 2 and outlet(discharge) flange 3; First carry out sealability test, inert gas argon gas is entered in pipe-line system with the pressure of 4Mpa, after keeping 40min, as without gas leak phenomenon, then pressure is reduced to 1.0Mpa, after keeping 18min, as then opened inlet ball valve 4 with the aperture of 8%/min without gas leak phenomenon, when the aperture of inlet ball valve 4 is greater than 50%, open vent ball valve 10, until meet operating mode needs with the aperture of 10%/min.
Like this, in this combustion gas building regulation boxes, be provided with pressure governor, outlet pressure is stablized, and be furnished with superelevation, super-low voltage cut-out resetting structure, reset more convenient; Arrange the curved mouth ball valve of venting, avoid the excessive accident that causes of outlet pressure to occur, increase reliability and the Security of equipment, improve the working life of equipment, easy to maintenance, dismounting is simple, reduces costs.
