Enter piping of pulsing, fluid pressure pulse is cut down by hemispherical end socket and orifice plate, and inlet tube is mainly stored up to pressure vessel
Accumulation of energy amount, and installation site is normally at horizontal direction, can not achieve output pressure and is reduced to a certain exact numerical.
Utility model content:
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of increase-volume decompressor, the increasing
Working fluid tubing internal diameter can not only be increased moment by holding decompressor, changed orifice size, and change the kinetic energy of fluid, made
At the different pressure losses, realize that pressure is reduced to particular value.
The purpose of this utility model solves by the following technical programs:
One end bottom of a kind of increase-volume decompressor, including increase-volume container, increase-volume container is provided with inlet, the other end

Speed and pressure reduce step by step；The lowest part of increase-volume container is provided with leakage fluid dram.
The internal diameter of the liquid outlet is greater than the internal diameter of inlet, and the internal diameter of increase-volume container is 6 times of inlet internal diameter.
The labyrinth type choke apparatus is made of at least 5 layers of semiclosed baffle, and every layer of semiclosed baffle staggered floor uniformly divides
Cloth is divided into multiple dioptric type cells inside increase-volume container, and by increase-volume container.
The utility model has the beneficial effects that:
1, the utility model increase-volume decompressor can make rapidly flow rate of liquid by increase-volume container and labyrinth type choke apparatus
Change with the kinetic energy of fluid, cause the different degrees of pressure loss, realizes pressure reduction to specific exact value.
2, the utility model increase-volume decompressor, is not influenced by extraneous factor, and the input pressure fluctuation of fluid will not cause
The fluctuation of output pressure, to solve the problems, such as output pressure fluctuation and output pressure failure of adjustment.
3, not by place and environmental restrictions, installation direction can select the installation of the utility model increase-volume decompressor as needed
Either direction setting.
4, the utility model increase-volume decompressor is high-efficient, and performance is stablized, noiseless, manufacture, installation, maintenance and operation letter
Just, save the cost.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model increase-volume decompressor；
Fig. 2 is the semiclosed baffle arrangement schematic diagram in the direction A in Fig. 1；
Wherein, 1- increase-volume container, 2- labyrinth type choke apparatus, 3- inlet, 4- liquid outlet, 5- leakage fluid dram, P1For feed liquor
The pressure of fluid, P at mouthful2For the pressure of fluid at liquid outlet.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawing:
Referring to Fig. 1 and Fig. 2, one end bottom of a kind of increase-volume decompressor, including increase-volume container 1, increase-volume container 1 is provided with
Inlet 3, the bottom of the other end are provided with liquid outlet 4, and the internal diameter of liquid outlet 4 is greater than the internal diameter of inlet 3, increase-volume container it is interior
Diameter is 6 times of inlet internal diameter；Increase-volume container 1 is internally provided with labyrinth type choke apparatus 2, and labyrinth type choke apparatus 2 is realized
The speed and pressure of fluid reduce step by step；The lowest part of increase-volume container 1 is provided with leakage fluid dram 5.
As can be seen from Figure 1: when the utility model is located at horizontal direction, the pressure of fluid is P at inlet 31, work as fluid
Increase-volume container 1 is reached by inlet 3, fluid circuit internal diameter is increased by 1 moment of increase-volume container, changes fluid cross-section face
Product realizes that the first time of Fluid pressure reduces.
According to the specific requirement used, fluid is needed to reach specific numerical value P by pressure when liquid outlet 42, therefore this reality
With at least 5 layers of novel semiclosed baffle, and staggered floor is evenly distributed on inside increase-volume container 1.Since fluid passes through labyrinth type choked flow
Frictional resistance effect is generated when device 2, fluid makes flows decrease along journey friction and local resistance along runner, and fluid is distributed by staggered floor
Semiclosed baffle when generate resistance, increase fluid pressure loss, reach decompression purpose.Therefore when fluid passes through inlet 3
Into after increase-volume container 1, multiple dioptric type cells that increase-volume container is divided by semiclosed baffle are passed sequentially through, multiple dioptric types are small
Room changes the speed of fluid and the kinetic energy of fluid, causes the different degrees of pressure loss, and realization reduces step by step, finally uses liquid
The Fluid pressure of mouth 4 is reduced to P2.The utility model increases fluid circuit internal diameter by 1 moment of increase-volume container, in conjunction with multilayer half
Closed guard reduces Fluid pressure step by step, so that the input pressure of fluid is fluctuated the fluctuation that will not cause output pressure, effectively solves
The problem of output pressure fluctuation and output pressure failure of adjustment.
Pass through pressure value P when liquid outlet if necessary to fluid2It is smaller, semiclosed baffle can be continued growing, and uniformly divide
Cloth.
The increase-volume decompressor installation direction of the utility model can select either direction to be arranged as needed, work as vertical direction
When installation, the pressure P of fluid at inlet1, realize that the first time of Fluid pressure reduces by increase-volume container 1, then successively lead to
Multiple dioptric type cells that increase-volume container is divided by more than half closed guards, reduce Fluid pressure step by step, the stream of final liquid outlet 4
Body pressure is reduced to P2, still can satisfy the output pressure of requirement.
Liquid freezes in increase-volume container 1 in cold climates in order to prevent, or increase-volume is discharged in time in the case where not using
Liquid in container 1, the utility model are provided with leakage fluid dram 5 in the lowest part of increase-volume container 1.
