Description

The Y type impacts cuts down automatic regulating type flow stabilizer

Technical field

The utility model relates to a kind of fluid flow stabilizer, specifically, is that a kind of Y type impacts the automatic regulating type flow stabilizer of reduction.

Background technique

Carrying liquid by pipeline is a kind of technological means commonly used, if the pressure in the pipeline changes slightly, or infiltration gas is arranged in the pipeline, the phenomenon that the liquid of this section pipeline of then flowing through has flow-disturbing produces, the amount that unit time liquid flows out just can't be kept stable, will cause the damage of back precision type instrument.

Flow control method commonly used at present is to carry out flow control by the bore that the mounting medium fluid passes through, as Chinese patent CN2615714, the technological scheme that adopts is: water pump, flow transducer and electric ball valve are connected in turn on the pipeline, by the rotating speed of computer and Frequency Converter Control water pump and the opening angle of electric ball valve, come control flow rate, its shortcoming is: (1) is though the energy control flow rate, but can not eliminate effectively because of system pressure changes the compression shock that causes, can cause the damage of pipeline back precision type instrument equally; (3) be directly installed on the pipeline, equipment failure maintenance inconvenience often needs to stop fully the operation of this pipeline; (4) bypass then engineering work load and space requirement requirement raising are installed, increase construction cost.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of Y type that can current stabilization can cut down water flow impact pressure again to impact and cuts down automatic regulating type flow stabilizer.

In order to address the above problem, Y type of the present utility model impacts cuts down automatic regulating type flow stabilizer, comprise by intake pipe, " Y " type three-way pipe that outlet pipe links to each other with side pipe and constitutes, the mouth of pipe at described side pipe is provided with cover plate, and in described side pipe, be provided with constant-current stabilizer, this constant-current stabilizer comprises the tubular outer tube, upper and lower end and inside at this outer tube are respectively equipped with, down, central diaphragm, the inner chamber of outer tube is divided into two-part up and down, this upper clapboard is located at the outlet port of described intake pipe it is sealed, this lower clapboard is installed in the inboard of described cover plate, on described outer tube, be provided with the interior pipe of tube wall band through hole in the inner chamber, should in the two ends of pipe be separately fixed at described on, on the central diaphragm, be somebody's turn to do on the interior Guan Jing, the through hole at central diaphragm middle part is communicated with the lower inner cavity of described intake pipe and described outer tube, piston and elastic member are housed in the pipe in this, and this elastic member is used to regulate described piston between piston and described central diaphragm; On described upper clapboard, be provided with for fluid enter manage in described and outer tube between through hole; On the tube wall of described outer tube lower inner cavity, be provided with the through hole that flows out for fluid.

During use, the utility model is inserted in the pipeline, in the pipe, enter again in the lower inner cavity of outer tube in the annular cavity of the fluid in the intake pipe between interior pipe and outer tube enters, flow in the outlet pipe at last.When fluid flow increases or reduces, to produce pressure difference at the upper and lower of piston, piston is moved up and down in interior pipe, like this, can not only cut down the hydrodynamic pressure energy, with the eliminate fluid compression shock, and the little hole number of passing through for fluid on the inner pipe wall is changed, thereby reach the purpose of regime flow.

In technique scheme, described elastic member is a spring.

In technique scheme, the outside tube wall of described side pipe outwards protrudes, and this projection increases the shape chamber of converging of this side pipe and outlet pipe near described intake pipe, and the fluid that is beneficial to flow out from constant-current stabilizer flows in the outlet pipe swimmingly.

In technique scheme, the angle of the shaft axis of described side pipe and the shaft axis of described outlet pipe is 30～60 degree.

In technique scheme, described lower clapboard is installed on the described cover plate through screw, so that the maintenance constant-current stabilizer.

In technique scheme, be equipped with flange plate at the mouth of pipe of described intake pipe and outlet pipe.

Compared with prior art, the beneficial effects of the utility model are: can cut down water flow impact pressure again by current stabilization, effectively ensure the stability of flow system flow; In addition, the Y type is designed to maintenance great convenience is provided, and need not connect bypass, saves construction cost.
