Abstract
The invention discloses a double-cavity pressurization connector. The double-cavity pressurization connector comprises a liquid inlet pipe, a primary pressurization chamber, a secondary pressurization chamber and a liquid outlet pipe which are communicated together in sequence, wherein a primary pressurization cavity is arranged in the primary pressurization chamber; a primary baffle is arranged between the primary pressurization cavity and the liquid inlet pipe and provided with a primary liquid inlet; a secondary pressurization cavity is arranged in the secondary pressurization chamber; a secondary baffle is arranged between the secondary pressurization cavity and the primary pressurization cavity and provided with a secondary liquid inlet; the liquid inlet pipe and a liquid storage tank are communicated with the liquid outlet pipe sequentially through the primary liquid inlet, the primary pressurization cavity, the secondary liquid inlet and the secondary pressurization cavity. According to the technical scheme, liquid is pressurized through the primary pressurization cavity and the secondary pressurization cavity and then enters a small-diameter pipeline after being pressurized, stress is not increased suddenly in the radial direction of the small-diameter pipeline, the stress is relatively balanced, and the service life is prolonged.
Description
Technical field
The invention belongs to supercharging equipment field, especially relate to a kind of bicavate supercharging joint.
Background technique
In current pipeline connection procedure, thickness two pipelines, when connecting thin diameter pipes supercharging, generally all directly to link together by thick diameter pipes.This Placement causes fluid pressure in interface position pipeline to increase suddenly, and the unexpected pressure increase of radial direction of thin diameter pipes declines easy rupture life, and thickness pipeline Bonding pressure is unstable, and impact uses.
Summary of the invention
In order to make up the defect that above-mentioned different-diameter pipeline connects, the present invention proposes a kind of bicavate supercharging joint.
Its technological scheme is, a kind of dual cavity supercharging joint, comprise the liquid inlet pipe be communicated to successively together, elementary pumping chamber, secondary pumping chamber and drain pipe, wherein, elementary booster cavity is provided with in described elementary pumping chamber, be provided with elementary baffle plate between elementary booster cavity and liquid inlet pipe, elementary pressuring baffle has elementary inlet opening; Secondary booster cavity is provided with in described secondary pumping chamber, secondary baffle plate is provided with between secondary booster cavity and elementary booster cavity, secondary pressuring baffle has secondary inlet opening, described liquid inlet pipe, together with liquid container to be communicated to drain pipe by elementary inlet opening, elementary booster cavity, secondary inlet opening and secondary booster cavity successively.In the technical program, liquid is through elementary booster cavity and secondary booster cavity supercharging, and enter thin diameter pipes again after being improved by its pressure, thin diameter pipes radial direction can not increase suddenly stressed, and stressed relative equilibrium improves its life-span; Simultaneously two booster cavities have again the effect of steady pressure, can compensator or trimmer pressure when thick diameter pipes internal pressure is unstable, reduce the injury to thin diameter pipes.
Described elementary inlet opening has multiple, and the cross-section area of each elementary inlet opening is all less than the cross-section area of drain pipe, and the cross-section area sum of all elementary inlet openings is greater than the cross-section area of drain pipe.In the technical program, the diameter of elementary inlet opening ensures that drain pipe flow velocity needs can not cause liquid inlet pipe overpressure again simultaneously, facilitates liquid inlet pipe pressure to enter elementary booster cavity.
Described secondary inlet opening has multiple, and the cross-section area of each secondary inlet opening is all less than the cross-section area of drain pipe, and the cross-section area sum of all secondary inlet openings is greater than the cross-section area of drain pipe.
The cross-section area of described secondary liquid inlet pipe is greater than the cross-section area of elementary inlet opening and is less than 1/16th of drain pipe rank street area.In the technical program, due to the characteristic of liquid pressure, when pressure is consistent, the larger pressure of caliber is larger, and namely flow velocity is larger, improves flow rate of liquid, reduces in elementary pumping chamber and bears, improve the fluid pressure of secondary pumping chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
Embodiment as shown in Figure 1.A kind of dual cavity supercharging joint, comprise be communicated to successively together liquid inlet pipe 1, elementary pumping chamber 2, secondary pumping chamber 3 and drain pipe 4, wherein, elementary booster cavity 21 is provided with in described elementary pumping chamber, be provided with elementary baffle plate 22 between elementary booster cavity and liquid inlet pipe, elementary pressuring baffle have elementary inlet opening 23; Secondary booster cavity 31 is provided with in described secondary pumping chamber, secondary baffle plate 32 is provided with between secondary booster cavity and elementary booster cavity, secondary pressuring baffle has secondary inlet opening 33, described liquid inlet pipe, together with liquid container to be communicated to drain pipe by elementary inlet opening, elementary booster cavity, secondary inlet opening and secondary booster cavity successively.In the present embodiment, described elementary inlet opening has multiple, and the cross-section area of each elementary inlet opening is all less than the cross-section area of drain pipe, and the cross-section area sum of all elementary inlet openings is greater than the cross-section area of drain pipe.Described secondary inlet opening has multiple, and the cross-section area of each secondary inlet opening is all less than the cross-section area of drain pipe, and the cross-section area sum of all secondary inlet openings is greater than the cross-section area of drain pipe.The cross-section area of described secondary liquid inlet pipe is greater than the cross-section area of elementary inlet opening and is less than 1/16th of drain pipe rank street area.
Due to the characteristic of liquid, when its pressure stable and consistent, caliber is thicker, and pressure is larger.According to this principle, the present invention when in use can be effectively slow by feed liquor velocity in pipes, and inject liquid outlet after the lifting liquid pressure that pressure is low and discharge, pressurization reduces the burden to liquid inlet pipe and drain pipe, improves its life-span.Feed liquor liquid in pipe is imported elementary booster cavity by elementary inlet opening of the present invention, pressure is produced after liquid accumulation in elementary booster cavity, because secondary inlet opening caliber is larger, its pressure is relatively large, improve its feed liquor flow velocity, drain pipe caliber again relative secondary inlet opening is comparatively large, and its pressure is improved again, more adds its flow velocity.Two booster cavities play pressure stabilization function again simultaneously, reduce pressure surely on the impact of drain pipe.
In sum, not whole intension of the present invention: after this, all to have within do by invention subject spirit any amendment, replacement until improve the projects such as upgrading, include within protection scope of the present invention.
