Abstract
It is specifically a kind of to realize aqueous vapor isolation and the constant pressure regulator of pressure difference the invention belongs to a kind of pressure regulator.Purpose is that the gas that ground installation is inputted into closed containing cavity under water by pipeline forms certain pressure in cavity volume, the difference of the hydraulic pressure of the pressure value and any depth remains constant and air-flow is discharged to by dedicated line in air, the field of view of diving support personnel when improving underwater operation, meanwhile, be conducive to the monitoring of surface personnel.It is discharged to the invention enables the gas of closed containing cavity under water by dedicated line in air, makes underwater operation field of view clear, meanwhile, be conducive to the monitoring of diving support personnel and surface personnel.
Description
Technical field
It is specifically a kind of to realize aqueous vapor isolation and the constant pressure regulation of pressure difference the invention belongs to a kind of pressure regulator
Device.
Background technology
At present, the closed containing cavity of underwater operation is the gas for providing continuous particular flow rate by pipeline by ground installation,
By pressure regulator control and maintain in cavity volume have certain pressure, due to need keep air-flow circulation, therefore, cavity volume need
Gas is discharged into water, now, the field of view of diving support personnel outside the aeration closed containing cavity produced is vented, together
When be also unfavorable for the monitoring of surface personnel.
The content of the invention
The purpose of the present invention is that the gas that ground installation is inputted into closed containing cavity under water by pipeline forms one in cavity volume
The difference of the hydraulic pressure of fixed pressure, the pressure value and any depth remains constant and air-flow is discharged to air by dedicated line
In, the field of view for the support personnel that dived under water when improving underwater operation, meanwhile, be conducive to the monitoring of surface personnel.
The present invention takes following technical scheme：It is a kind of to realize that aqueous vapor is isolated and the constant pressure regulator of pressure difference, including with
The closed containing cavity and adjuster of air inlet pipe connection, closed containing cavity, which is provided with cavity volume opening, cavity volume opening, is provided with adjuster, institute
The adjuster stated includes push rod, nut, handwheel, spring, bellows, support frame, housing and valve, and push rod is by nut by spring
Compress and be fixed on handwheel, handwheel is arranged at the opening of case top and is threadedly coupled with housing, enclosure interior is provided with branch
Support, is provided with bellows, support frame between support frame and handwheel and is fixed with valve, valve one end is connected with bellows, valve
The other end seals the opening of housing bottom, and the pre-compression force of spring acts on the bottom surface of bellows by push rod and passes to branch
Valve on support, the groove of case inside is provided with the O-ring I for making to be tightly connected between bellows and housing, hull outside
Groove is provided with the O-ring II for making to be tightly connected between closed containing cavity and housing, and housing is connected with exhaust outlet.
The effective area of described valve is equal to the effective area of bellows.
During ground installation is supplied by dedicated line to closed containing cavity, when gas pressure power is more than in closed containing cavity
During the pre-compression force of spring, valve is opened, and air pressure is vented in air by dedicated line in closed containing cavity, when closed containing cavity institute
During the underwater penetration change at place, hydraulic pressure acts on the bottom surface of bellows by the hole on handwheel, closes valve, works as closed containing cavity
Interior air pressure, which is increased to, overcomes the late gate of making a concerted effort of hydraulic pressure and spring to be again turned on, it is ensured that the difference of air pressure and hydraulic pressure in closed containing cavity
A steady state value is kept, the value is the pre-compression force of spring.
The device have the advantages that：Air is discharged to by dedicated line the invention enables the gas of closed containing cavity under water
In, make underwater operation field of view clear, meanwhile, be conducive to the monitoring of diving support personnel and surface personnel.
