The pressure auto-balancing regulating device comprises a tube sheet (1) which is connected with a spherical seal (3) by the pass partition (2), and the pass partition is connected with the spherical differential pressure regulating device of the pass partition of the high-pressure heater water chamber. The pressure auto-balancing regulating device is designed for the high-pressure heater water chamber.
Description
Technical field:
The utility model relates to a kind of high chamber barrier pressure self-balancing regulator that adds.
Background technology:
High-pressure heater is one of key equipment of heat regenerative system in the generating set, and its normal safe operation is that Power Plant is exerted oneself and improved the effective guarantee of thermal efficiency of cycle.Hydroecium directly has influence on the high-pressure heater safety work as the important component part of high-pressure heater.High-pressure heater is because the pressure reduction existence of chamber barrier both sides, may cause distortion or the damage of chamber barrier, so the high-pressure heater chamber barrier adopts the modes such as flexibility or expansion joint to connect more at present, to eliminate high pressure reduction stress and the distortion that hydroecium produces that add, but because of the hydroecium space little, all larger at the in-built distributing water room of hydroecium involucrum workload, labour intensity and live load, and the large usage quantity of material.
Summary of the invention:
The purpose of this utility model provides a kind of high difficulty that adds the processing of hydroecium internals and assembling that reduced, and the height of being convenient to produce adds chamber barrier pressure self-balancing regulator.
Above-mentioned purpose realizes by following technical scheme:
A kind of high chamber barrier pressure self-balancing regulator that adds, its composition comprises: tube sheet, described tube sheet connects dome head by pass partition, and described pass partition connects the high ball-type regulator that adds chamber barrier pressure reduction.
Described height adds chamber barrier pressure self-balancing regulator, the ball-type regulator that described height adds chamber barrier pressure reduction comprises lower linking tube, described lower linking tube upper end is threaded connection and connects the hollow pipe bottom, form a cavity by connecing the hollow pipe bottom in the connection of described lower linking tube upper end, in the described cavity small ball is housed, described lower linking tube with described on to connect the end that hollow pipe is connected be sphere, described sphere and described small ball are used in conjunction with, described lower linking tube has the current through hole, connects hollow tube wall on described and has one group of aperture.
Described height adds chamber barrier pressure self-balancing regulator, and described dome head bulb part connects respectively feedwater outlet pipe and feedwater oral siphon.
Beneficial effect:
1. the utility model is used for pass partition in conventional thermoelectricity, each grade unit high-pressure feed-water heater hydroecium of nuclear power, can eliminate Yin Gaojia and start between instantaneous feedwater import and export and the high stress that adds the pressure reduction generation of normal operating conditions pass partition both sides.
The utility model is by the action of small ball, guaranteed that height adds chamber barrier both sides differential pressure self-balancing, realize eliminating the high stress that adds the pressure reduction generation of normal operating conditions pass partition both sides between the instantaneous feedwater import and export of startup with height that adds, avoided damaging the high chamber barrier that adds.
The pressure that the utility model relies on gravity, buoyancy and pressure reduction to cause fully is different and then realize the pressure self-balancing effect; Realized that the high hydroecium that adds needn't add the flexible internals of hydroecium for elimination pressure reduction produces the various height that design, and reduces the high hydroecium internals that add to the consumption of material.
The utility model has been eliminated height and has been added the high stress that adds the pressure reduction generation of normal operating conditions pass partition both sides between the instantaneous feedwater import and export of startup with height that adds of the interior steel ball position adjustments of chamber barrier pressure self-balancing regulator.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.

The specific embodiment:
Embodiment 1:
A kind of high chamber barrier pressure self-balancing regulator that adds, its composition comprises: tube sheet 1, described tube sheet connects dome head 3 by pass partition 2, and described pass partition connects the high ball-type regulator 4 that adds hydroecium layering dividing plate pressure reduction.
Described height adds chamber barrier pressure self-balancing regulator, the ball-type regulator that described height adds hydroecium layering dividing plate pressure reduction comprises lower linking tube 5, described lower linking tube upper end is threaded connection and connects hollow pipe 6 bottoms, form a cavity 7 by connecing the hollow pipe bottom in the connection of described lower linking tube upper end, small ball 8 is housed in the described cavity, described lower linking tube with described on to connect the end that hollow pipe is connected be sphere, described sphere and described small ball are used in conjunction with, described lower linking tube has current through hole 9, connects hollow tube wall on described and has one group of aperture 10.
Described height adds chamber barrier pressure self-balancing regulator, and described dome head bulb part connects respectively feedwater outlet pipe 11 and feedwater oral siphon 12.
Embodiment 2:
Because the density of small ball is greater than the density of water, when height adds the feedwater entry and exit when not having the pressure reduction differential pressure too small, small ball drops to the sphere place that connects hollow pipe by self gravitation, realize fully contact with lower linking tube, block the mouth of lower linking tube current through hole, stop to feed water by on connect flowing of hollow pipe aperture; When adding, height feeds water out, entrance pressure reduction reaches certain difference, produce pressure in the hollow pipe aperture and increase because the increase of pressure reduction causes connecing, when on connect the hollow pipe aperture pressure when being increased to difference greater than the gravity of small ball and buoyancy, small ball and lower linking tube sphere place will produce the gap this moment, when adding chamber barrier both sides pressure reduction, height continues to increase, small ball breaks away from gradually and connects the hollow pipe sphere, in case small ball leaves the lower linking tube spherical, height add feedwater at once by on connect the clearance space that the hollow pipe aperture flows into lower linking tube and small ball, and then in lower linking tube, and flow into the feedwater outlet side from connecing the side wall of hollow pipe aperture, because incompressible characteristic of water, even a small amount of feedwater adds chamber barrier feedwater outlet side from high bonus point journey dividing plate feed-water intake side inflow to height, also will be very soon reach height adds the chamber barrier pressure at both sides and equates, at this moment, the gravity of small ball and the difference of buoyancy greater than because high add chamber barrier both sides pressure reduction different cause on connect the hollow pipe aperture and produce pressure, when feeding water out, when entrance pressure reduction is not enough to promote small ball and leaves lower linking tube sphere place, small ball relies on gravity to fall voluntarily, when small ball is got back to original fully sealing station, small ball again with on meet hollow pipe sphere place and contact fully, block the current port and realize fully sealing.
