Description
Technical field
The utility model relates to a kind of pressure reduction and regulates bleeder valve, and it is used for controlling the pressure difference value between the air-tight section cabin, makes it constitute certain pressure gradient.
Background technique
Pressure reduction is regulated important composition parts and the key equipment that bleeder valve is air-tight section pressure difference value control peculiar to vessel, and it is used for controlling the pressure difference value between the air-tight section cabin, makes it constitute certain pressure gradient.Thereby the air pressure of controlling between each Air Tight Compartment descends from the inside to the outside step by step, and when preventing that door between each Air Tight Compartment from opening, extraneous air spreads to air-tight section.
Summary of the invention
The technical problem that the utility model will solve provides a kind of pressure reduction and regulates bleeder valve, is used for self-powering type pressure release on the airtight regional circumference and possesses the function of Flow-rate adjustment, and is stable with the superpressure of keeping airtight intra-zone.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
Pressure reduction is regulated bleeder valve, mainly comprises handwheel, locking wheel, valve seat, outer cover, decide valve disc, decides disc seat, reed, external axle sleeve, valve seat insert, moves valve disc, valve rod; It is characterized in that:
Valve seat is disc type and has the vertical edge edge, is installed on each cabin bulkhead of air-tight section, and handwheel and locking wheel are arranged on valve rod and from valve seat, stretch out and be positioned at high pressure one side air-tight section, locking wheel next-door neighbour valve seat; The outside is interlocked with cylindrical Stainless Steel Valve outer cover and valve seat; Set gradually valve seat insert, moving valve disc, reed between valve seat and the outer cover, decide disc seat and decide valve disc, deciding valve disc can move horizontally adjusting along valve rod, and can be pressed on the seal ring; Valve rod adopts the straight-line motion mechanism of cover screw rod in the fluting steel pipe; Reed is pressed valve disc travel need adopt the two-man act chip, and each reed is taper type, two reed microcephalies offset major part respectively with decide valve disc and contact with moving valve disc.
Decide to be provided with on disc seat and the valve seat insert sealing cutting edge.
External axle sleeve is arranged on the valve rod outside.
Reed is the beryllium bronze reed.
Pressure reduction is regulated bleeder valve when applying working condition not, manually unclamps locking wheel, is rotated counterclockwise handwheel, decides valve disc and is pressed on the valve seat insert, tightens locking wheel simultaneously, and at this moment Pressure Relief Valve is in buttoned-up status.
Pressure reduction is regulated bleeder valve when applying working condition, manually unclamps locking wheel, the clockwise direction rotation hand wheel, and deciding valve disc can move to maximum travel position (when vertically installing, rising to the extreme higher position) to the outer cover direction.Moving valve disc was under reed 7 elastic force and closed the dress attitude this moment; When the pressure difference in each cabin of air-tight section reached specified value, moving valve disc moved unlatching to deciding the valve disc direction, and along with the pressure reduction between the cabin continues to increase, the aperture of moving valve disc also increases gradually, till standard-sized sheet.When pressure reduction between the cabin during, can make and decide the position that valve disc is in setting through regulating the elastic force of reed, thereby regulate between the air-tight section cabin pressure reduction to needed difference less than specified value.
With respect to existing technology, the beneficial effect of the utility model is:
Employing pressure reduction is regulated, and makes the pressure difference value between the air-tight section cabin constitute certain pressure gradient.
Pressure reduction is regulated bleeder valve and has been adopted the open type valve body structure, does not promptly have the sealed type runner, substitutes with the Stainless Steel Valve outer cover, significantly reduces flow resistance like this, has satisfied the requirement of the big flow of little latus rectum.
Adopt to regulate and decide the valve disc structure, price fixing can be pressed on the seal ring, guaranteed its closing function reliability.
Adopt the straight-line motion mechanism design of cover screw rod in the special-purpose fluting steel pipe, screw rod rotate regulate make decide that valve disc can not rotate can free linear slide, satisfied the freely regulated needs of valve disc travel.
Be employed in high pressure one side and regulate the mode of rotating screw bolt, the design locking wheel, the adjusting that makes it pressure reduction is more convenient, and can in time lock.
Seal ring has designed unique sealing cutting edge, and sealability improves a lot.
Adopt the two-man act chip to regulate the design of pressure reduction, adopt special-purpose new material beryllium bronze to be made into special-purpose reed.Press the structure that valve disc travel need be designed to the two-man act sheet, thereby satisfy the requirement of pressure reduction.
Description of drawings
Fig. 1 is that pressure reduction is regulated the bleeder valve structural drawing
Embodiment
For understanding the utility model better, the utility model is done further to describe below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, pressure reduction is regulated consisting of of bleeder valve: handwheel 1; Locking wheel 2; Valve seat 3; Outer cover 4; Decide valve disc 5; Decide disc seat 6; Reed 7; External axle sleeve 8; Valve seat insert 9; Moving valve disc 10; Valve rod 11.
Adopt the open type valve body structure, the bleeder valve outside is interlocked with cylindrical Stainless Steel Valve outer cover 4 replacement seal formula runners and valve seat 3, significantly reduces flow resistance like this, has satisfied the requirement of the big flow of little latus rectum.
Set gradually valve seat insert 9, moving valve disc 10, reed 7 between valve seat 3 and the outer cover 4, decide disc seat 6 and decide valve disc 5, deciding valve disc 5 can move horizontally adjusting along valve rod 11, and can be pressed on the seal ring 9, has guaranteed its closing function reliability;
Valve rod 11 adopts the straight-line motion mechanism design of cover screw rod in the special-purpose fluting steel pipes, screw rod rotate regulate make decide that valve disc 5 can not rotate can free linear slide, satisfied the freely regulated needs of valve disc travel.External axle sleeve 8 is arranged on valve rod 11 outsides.
