Description
Technical field
The utility model belongs to self-contained pressure regulator technical field, especially a kind of self-contained pressure regulator debugging apparatus.
Background technique
In the working site in thermal power plant, self-powering type (after valve) pressure regulator valve often to be used.The working principle of self-powering type (after valve) pressure regulator valve is: the upstream pressure of working medium, after the spool, valve seat throttling of pressure regulator valve, becomes downstream pressure.Downstream pressure is input to final controlling element lower film indoor through controlling pipeline act on, and the active force of generation and the reaction force of pressure regulator valve spring balance each other, and determine the relative position of spool, valve seat, control downstream pressure.When downstream pressure increases, the active force that P2 acts on also increases thereupon.Now, the active force of taking over a business is greater than the reaction force of spring, makes spool pass to the position of valve seat, until the reaction force of the active force of taking over a business and spring balances each other.At this moment, the circulation area of spool and valve seat reduces, and flow resistance becomes large, thus makes downstream pressure reduce to setting value.In like manner, when downstream pressure reduces, action direction is contrary to the above.
When using at the scene, need to adjust according to the spring of operating conditions to pressure regulator valve, the gamut changed at pressure to make pressure regulator valve reliably, action timely.But under this pressure regulator valve is arranged on special operating mode, do not possess field adjustable condition, be such as arranged on the positions such as the ammonia district of power station, hydrogen station, scene cannot be debugged this modulating valve.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of self-contained pressure regulator debugging apparatus, solves the problem cannot carrying out normal adjustment in working site to pressure regulator valve spring.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of self-contained pressure regulator debugging apparatus, comprise pressure source, pipeline, entrance needle type valve, inlet pressure table, inlet flange dish, outlet(discharge) flange dish, delivery gauge, outlet needle type valve and pipeline support frame, the outlet end of described pressure source is connected with pipeline, described entrance needle type valve, inlet pressure table and inlet flange dish are successively set on the pipeline of self-contained pressure regulator side, the entry end of this inlet flange dish and self-contained pressure regulator is installed together, outlet end and the outlet(discharge) flange dish of this self-contained pressure regulator are installed together, this outlet(discharge) flange dish, delivery gauge and outlet needle type valve are arranged on the pipeline of self-contained pressure regulator opposite side, the bottom that this pipeline support frame is arranged on pipeline plays a supportive role.
And described pressure source adopts nitrogen bottle.
And described inlet flange dish and outlet(discharge) flange dish are packed on pipeline by welding manner.
Advantage of the present utility model and good effect are:
1, needle type valve and pressure gauge are arranged on the two ends pipeline of self-contained pressure regulator using nitrogen bottle as pressure source by the utility model respectively, pipeline pressure is regulated by needle type valve, pressure changing is observed by pressure gauge, can debug pressure regulator valve in laboratory, equipment operating environment is good, is convenient to adjustment, the degree of accuracy that spring is adjusted improves, and structure is simple, easy to assembly, be easy to realize.
2, the utility model pressure is easy to adjust, and observe valve event directly perceived, valve Adjustment precision is high.
3, the utility model can be adjusted valve in advance and installs, considerably increases safety coefficient, avoids on-the-spotly to cause the impact of fluctuation to system pressure due to adjustment valve, and system reliability and Security are effectively strengthened.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of self-contained pressure regulator debugging apparatus, as shown in Figure 1, comprise nitrogen bottle, pipeline, entrance needle type valve, inlet pressure table, inlet flange dish, outlet(discharge) flange dish, delivery gauge, outlet needle type valve and pipeline support frame, the outlet end of described nitrogen bottle is connected with pipeline, described entrance needle type valve, inlet pressure table and inlet flange dish are successively set on the pipeline of self-contained pressure regulator side, the entry end of this inlet flange dish and self-contained pressure regulator is installed together, outlet end and the outlet(discharge) flange dish of this self-contained pressure regulator are installed together, this outlet(discharge) flange dish, delivery gauge and outlet needle type valve are arranged on the pipeline of self-contained pressure regulator opposite side, the bottom that this pipeline support frame is arranged on pipeline is for pipeline, entrance needle type valve, inlet pressure table, inlet flange dish, outlet(discharge) flange dish, delivery gauge, the support of outlet needle type valve.In the present embodiment, inlet flange dish and outlet(discharge) flange dish are packed on pipeline by welding manner, and are docked with self-contained pressure regulator by inlet flange dish and outlet(discharge) flange dish.
The utility model is arranged in laboratory, manually regulates the aperture simulated field pressure change of valve on pipeline, for being provided test conditions by adjustment pressure regulator valve, thus the spring position of modulating valve of adjusting.Its adjustment process is: (1) utilizes nitrogen bottle as pressure source, and nitrogen bottle exports nitrogen by pipeline and passes through needle type valve pilot pressure; (2) by inlet pressure table that pipeline connects and delivery gauge, change value of pressure is observed; (3) by the outlet needle value that pipe end is equipped with, system exhaust is carried out and the pressure adjustment that disappears; (4) connect adjustment behind the door during debugging, bulge test is carried out to pipeline, eliminate leak source; (5) when adjust regulating valve door spring position time, open entrance needle value, close outlet needle value, maintain the scope that pipeline pressure is requiring, according to the instruction of inlet pressure table, regulate entrance needle type valve pressure is regulated suitable after, according to the instruction adjustment spring position of delivery gauge; (6) test after valve adjustment: first by pressure after slow opening conduits upper outlet needle type valve change adjustment doors, observe adjustment doors action situation, now valve should be opened; Then will export needle value to close, outlet pressure increases gradually, and adjustment door should be closed gradually.Observe action situation, judge to adjust door spring and whether adjust suitable, again adjust time improper; (7) total Test qualified after, close entrance needle value, open outlet needle value, in emptying pipe, gas disappears pressure.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other mode of executions drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
