Abstract
The invention belongs to a pressure regulator, and particularly relates to a pressure regulator capable of achieving water and gas separation and the constant pressure difference. The pressure regulator aims at forming certain pressure in a containing cavity through gas which is input into the underwater closed containing cavity by a ground device through a pipeline. The difference between the pressure value and the water pressure of any depth is kept constant so that gas flow can be discharged into the atmosphere through a special pipeline, the view field of diving support personnel is improved during underwater work, and meanwhile monitoring of ground workers is facilitated. By means of the pressure regulator, gas in the underwater closed containing cavity is discharged into the atmosphere through the special pipeline, the view field of the underwater work is clear, and meanwhile the monitoring of the diving support personnel and the ground workers is facilitated.
Description
Technical field
The invention belongs to a kind of pressure regulator, specifically a kind ofly realize aqueous vapor isolation and the constant pressure regulator of pressure reduction.
Background technique
At present, the closed containing cavity of underwater operation is the gas being provided continuous print particular flow rate by ground installation by pipeline, controlled by pressure regulator and maintain in cavity volume that there is certain pressure, owing to needing the circulation keeping air-flow, therefore, cavity volume needs gas to enter in water, now, the field of view of the aeration closed containing cavity outside diving support personnel that exhaust produces, is also unfavorable for the monitoring of surface personnel simultaneously.
Summary of the invention
The gas that the object of the invention is ground installation inputs closed containing cavity under water by pipeline forms certain pressure in cavity volume, the difference of the hydraulic pressure of this force value and any degree of depth remains constant and makes air flow energy be discharged in air by dedicated line, the field of view of diving support personnel when improving underwater operation, meanwhile, the monitoring of surface personnel is conducive to.
The present invention takes following technological scheme: a kind ofly realize aqueous vapor isolation and the constant pressure regulator of pressure reduction, comprise the closed containing cavity and regulator that are connected with suction tude, closed containing cavity is provided with cavity volume opening, cavity volume opening is provided with regulator, described regulator comprises push rod, nut, handwheel, spring, bellows, supporting frame, housing and valve, spring-compressed is fixed on handwheel by nut by push rod, handwheel is arranged on the opening of case top and is threaded with housing, enclosure interior is provided with supporting frame, bellows is provided with between supporting frame and handwheel, supporting frame is fixed with valve, valve one end is connected with bellows, the opening of housing bottom seals by the valve the other end, the pre-compression force of spring acts on the bottom surface of bellows and the valve passed on supporting frame by push rod, the groove of case inside is provided with the O shape circle I making to be tightly connected between bellows and housing, the groove of hull outside is provided with the O shape circle II making to be tightly connected between closed containing cavity and housing, housing is communicated with relief opening.
The useful area of described valve equals the useful area of bellows.
At ground installation by dedicated line in closed containing cavity air feed process, when closed containing cavity internal air pressure active force is greater than the pre-compression force of spring, valve open, closed containing cavity internal air pressure is vented in air by dedicated line, when the underwater penetration residing for closed containing cavity changes, hydraulic pressure acts on the bottom surface of bellows by the hole on handwheel, make valve closing, again open when closed containing cavity internal air pressure increases to the late gate of making a concerted effort overcoming hydraulic pressure and spring, ensure that the difference of closed containing cavity internal air pressure and hydraulic pressure keeps a steady state value, this value is the pre-compression force of spring.
The beneficial effect that the present invention has: the invention enables the gas of closed containing cavity to be under water discharged in air by dedicated line, makes underwater operation field of view clear, meanwhile, is conducive to the monitoring of diving support personnel and surface personnel.
