Abstract
The utility model relates to a fluid damper whose casing is in a cylinder shape. The utility model is composed of a cylinder head (7) and a cylinder body. The cylinder head is connected with a measuring instrument and a screwed plug (1) respective through joints (8, 9), and a spiral type spring tube (4) is arranged in the casing. The utility model has the function for stabilizing the fluid pressure of a pipeline, and the utility model can prevent the false operation and clean tube block. The goal of the protection of a test instrument can be realized, and the utility model can be a protector of the test instrument in a pipeline fluidic system.
Description
The utility model belongs to the stable-pressure device in the Fluid Transmission and Control loop.
In the Fluid Transmission and Control loop, because pump structure, or the action of pipe valve and selector valve and executive component is when causing the fluidised form rapid change, then produce fluctuation pressure (vibration pressure and surge pressure), the pressure of these variations and flow cause surveying instrument to damage and indicate malfunctioning, and cause system's misoperation, cause damage to production.In the existing hydraulic pressure industry, the multiple tracks filtrating equipment is set, these filtrating equipments play the fluctuation pressure in the pipeline and absorb and damping function; In the hydroelectric power industry, the impurity fineness ratio in the water is bigger, adopts oil pressure damping way to result in blockage, and makes instrument lose the measurement effect.As seen, in the existing industrial pipeline system, there is complex structure in the device that reduces the decay of liquid pulsation pressure, the deficiency that is easy to stop up.
It is a kind of simple in structure that the purpose of this utility model is to provide, and makes nonclogging fluid damper easily.
Characteristics of the present utility model are that housing is the ball tubular, be formed by connecting by two ball tube heads (7) and cylinder (3), bourdon tube (4) is spiral, and place in the housing, one of bourdon tube is connected with test splice (8), the other end is free interface, makes liquid stream freely enter spiral spring pipe (4).
Lower end at damper has opening, cooperates with plug (1) by joint (9), is used to remove shoal materials.
Structure of the present utility model specifies by embodiment:
Accompanying drawing is the fluid damper structural drawing.Ball tube head (7) is stamping forming by corrosion resistant plate, at first ball tube head (7), spiral spring pipe (4) are tightened with test splice (8), and with locking nut (6) with its locking, reusable connector (9) welds together with another ball tube head (7) and cylindrical shell (3), and the butt welded seam check of polishing, the opening of a ball tube lower end is connected with plug (1) with packing ring by joint (9), and the opening on the cylindrical shell (3) is connected with throttle pipe by joint (5).
When fittings body (5) is connected with tested pressure piping, pressure wave with impact, pulsation at first enters housing, principle because of expandable cavity, carry out attenuation of the first kind, then fluid enters spiral spring pipe (4) by free interface, carries out the attenuation of the second kind (utilizing elongated hole and resiliently deformable), enter the middle elongated hole of test splice (8) at last and do last decay, the tested instrument of steady force value after the decay records, and surge pressure is not just damaged test instrumentation like this, has prevented misoperation yet.
When impurity content was big in the liquid medium, these impurity were opened plug (1) with its eliminating by self particle weight deposition tube end.Therefore, chance that elongated hole in bourdon tube (4) and the test splice (8) is stopped up just seldom can wholely adopt stainless steel material, has improved the reliability of instrumentation.Security.
Effect of the present utility model is:
1. can be with the liquid pulsation decline of pressure in the pressure pipeline, with the protection test instrumentation, and avoided the misoperation that causes thus.
2. the impurity of energy scavenger precipitation avoids testing conduit to stop up, and guarantees the normal operation of test instrumentation.
3. have antirust, corrosion-resistant, the Applicable media scope is wide and simple in structure, the advantage that is easy to make.
The utility model is applicable to the fluid piping system with surge pressure and fluctuation pressure.
Claims (2)
1, a kind of fluid damper is made up of housing and bourdon tube, it is characterized in that housing is the ball tubular, be formed by connecting by two ball tube heads (7) and cylinder (3), bourdon tube (4) is spiral placing in the housing, and one is connected with test splice (8), and one is free interface.
2, according to the described damper of claim 1, it is characterized in that there is an opening lower end of ball tube head (7), be connected with plug (1) by joint (9).
