Abstract
Nitrogen air balance voltage regulator device relates to the device that can balance nitrogen gas conveying system pressure. Establish air pressure adjusting valve at present for solving on nitrogen gas pipeline, under pressure -fired pressure range, adjustment accuracy is low, and the low scheduling problem of reliability designs. It includes the pressure balance jar and uses the gas buffer tank, pressure balance jar and with connecting through the connecting pipe between the gas buffer tank, the connecting pipe is connected with nitrogen gas pipeline, with being equipped with the outlet duct on the gas buffer tank, sealed liquid is equipped with in the pressure balance jar, be equipped with in the pressure balance jar and plug in the bottom tube, the upper end of plugging in the bottom tube is connected with the connecting pipe, and during the lower extreme of plugging in the bottom tube stretched into sealed liquid, there was the import of sealed liquid in pressure balance tank deck portion, and there is the seal fluid outlet in pressure balance tank bottoms portion, and pressure balance jar upper portion is equipped with gaseous evacuation pipe, liquid level sight glass in addition on the pressure balance jar. The advantage is that adjustment accuracy is high, and the reliability is high.
Description
Technical field:
The utility model relate to a kind of can the device of balance Nitrogen delivery system pressures.
Background technology:
Nitrogen overpressure can make system pressure excess load, damages system, causes production safety hidden danger.Traditional pressure control device is to set air pressure regulator in nitrogen gas delivery-line, arrange air pressure regulator to be disadvantageous in that under pressure-fired pressure limit, Adjustment precision is low, reliability is low, when air pressure adjustment defective valve, upstream device can be caused to damage, and serious also can cause work safety accident.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of accurate in the regulation of pressure-fired pressure limit downforce, and reliability is high, it is ensured that the nitrogen balance stable-pressure device of production safety.
Above-mentioned purpose is achieved in that it includes pressure balancing tank and uses gas surge tank, pressure balancing tank and being connected by connecting tube between gas surge tank, described connecting tube is connected with nitrogen gas delivery-line, described is provided with escape pipe with gas surge tank, pressure balancing tank is built with sealing fluid, bottom insert canal it is provided with in pressure balancing tank, the upper end of described bottom insert canal is connected with connecting tube, the lower end of bottom insert canal extend in sealing fluid, there is sealing fluid import pressure balance tank top, pressure balance pot bottom has seal fluid outlet, pressure balancing tank top is provided with gas evacuated tube, liquid level visor is also had on pressure balancing tank.
The utility model has the advantages that: be connected by pressure balancing tank with by the connecting tube between gas surge tank with the nitrogen gas delivery-line in air pressure regulator downstream; by sealing liquid level in regulation pressure balancing tank; precisely can regulate between 0.1 0.3 atmospheric pressure; when air pressure adjustment defective valve; pressure in pressure balancing tank reaches critical value; sealing fluid in bottom insert canal will be forced out; the gas discharge pipe emptying on pressure balancing tank of the gas in nitrogen gas delivery-line; upstream device can be protected to be not damaged by, it is ensured that production safety.Additionally this apparatus structure is simple, it is easy to install and use.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
With reference to Fig. 1, it includes pressure balancing tank 1 and with gas surge tank 2, pressure balancing tank and being connected by connecting tube 3 with between gas surge tank, described connecting tube is connected with nitrogen gas delivery-line 4, described is provided with escape pipe 5 with gas surge tank, pressure balancing tank is built with sealing fluid 6, bottom insert canal 7 it is provided with in pressure balancing tank, the upper end of described bottom insert canal is connected with connecting tube, the lower end of bottom insert canal extend in sealing fluid, there is sealing fluid import 8 pressure balance tank top, pressure balance pot bottom has seal fluid outlet 9, pressure balancing tank top is provided with gas evacuated tube 10, liquid level visor 11 is also had on pressure balancing tank.
