Description

A kind of flow pressure stabilizer

Technical field

The utility model relates to a kind of feeding pressure stabilizing device being applied to fluid conveying, is specifically related to a kind of flow pressure stabilizer.

Background technique

Current fluid conveying is all undertaken by simple pipeline usually, such as, for the test of valve, is also all realize the conveying of fluid by this pipeline.Due in fluid delivery process, the running of water pump can produce certain Pulse wave by convection cell, cause the pulsation phenomenon of fluid, thus just the course of conveying of convection cell can produce pressure surge produce bubble phenomenon in fluid, these phenomenons finally just can cause the flow of the instability in fluid delivery process, and the transfer efficiency of fluid, the steadily aspect such as rate and valve testing precision all can be affected.Meanwhile, continue to enter due to fluid the damage being also easy to make twin conduit, the loss of pipeline is strengthened.

Model utility content

In order to solve the problems of the technologies described above, the utility model provides a kind of can effectively elimination and pulses and the flow pressure stabilizer of reduction pipe loss.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of flow pressure stabilizer, it comprises:

Container part, has the cavity vertically arranged in it, this container part is provided with and is communicated with this cavity and outside liquid entering hole;

Drain pipe, it has the tube body of the arranged direction being parallel to cavity, and the open top of this tube body extends towards the top-direction of cavity, and this open top has scarf.

Further, above-mentioned container part is vertically arranged tank body.

Further, the liquid outlet of above-mentioned drain pipe is positioned on the second tube body of horizontal arrangement, and the bottom of this second tube body and tube body is in being connected with intersecting vertically.

Further, the curved transition in joint of the second above-mentioned tube body and tube body.

Further, above-mentioned tube body is arranged on the central position of cavity.

Further, the gas-liquid ratio in above-mentioned cavity is 1: 2.

Further, above-mentioned scarf is formation of cutting sth. askew downwards towards fluid direction.

Further, above-mentioned scarf and the angle of horizontal plane are 45 °.

The utility model adopts the beneficial effect of above technological scheme to be: by arranging the container part with vertically arranged cavity, when from liquid outlet in cavity during infusion fluid, liquid just can continue from the bottom of cavity to its top to rise, in uphill process, liquid just upwards can produce pressure to the pressurized air above cavity, this pressurized air back that is under pressure produces reaction force to the liquid of below, and liquid is discharged from drain pipe again.Therefore, the working principle that the utility model innovatively applies " air is compressible, liquid is incompressible ", by the interaction between liquid and pressurized air, effectively eliminate the pulsation in liquid, just can solve the problem of pressure surge in liquid delivery process and bubble thus; Meanwhile, be there is by drain pipe the open top of scarf, the area of contact of open top and liquid is increased, thus reduce flow of fluid to the impact of pipeline, reduce the loss of pipeline.

Embodiment

Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.

In order to reach the purpose of this utility model, as shown in Figure 1-2, in the some of them mode of execution of a kind of flow pressure stabilizer of the present utility model, it comprises container part 1 and drain pipe 2, there is in container part 1 cavity 11 vertically arranged, this container part 1 is provided with and is communicated with this cavity 11 and outside liquid entering hole 12, drain pipe 2 has the tube body 21 of the arranged direction being parallel to cavity 11, the open top 211 of this tube body 21 extends towards the top-direction of cavity 11, and this open top 211 has scarf 212.

As shown in Figure 1-2, this device has the container part 1 of vertically arranged cavity 11 by arranging, when from tube body 21 in cavity 11 during infusion fluid, liquid just can continue from the bottom of cavity 11 to its top to rise, in uphill process, liquid just upwards can produce pressure to the pressurized air above cavity 11, this pressurized air back that is under pressure produces reaction force to the liquid of below, and liquid is discharged from drain pipe again.Therefore, the working principle that this device innovatively applies " air is compressible, liquid is incompressible ", by the interaction between liquid and pressurized air, effectively eliminate the pulsation in liquid, just can solve the problem of pressure surge in liquid delivery process and bubble thus; Meanwhile, be there is by drain pipe the open top of scarf, the area of contact of open top and liquid is increased, thus reduce flow of fluid to the impact of pipeline, reduce the loss of pipeline.

Wherein, as shown in Figure 1, container part 1 is specifically as follows vertically arranged tank body, or other forms of container, and such as horizontal tank body has vertically arranged cavity in it.Form the embodiment of preferably container part 1 thus.

In addition, as shown in Figure 1, container part 1 can also possess the known parts such as top cover 13 and leg 14, and these can know from prior art, and this is no longer going to repeat them.

As shown in Figure 1, the liquid outlet 221 of drain pipe 2 is positioned on second body 22 of horizontal arrangement, the bottom of this second tube body 22 and tube body 21 is in being connected with intersecting vertically, namely time drain pipe 2 extends in cavity 11 from liquid outlet 221, the bending of shape of vertical in cavity 11, the part of the drain pipe 2 after bending vertically extends to the top of cavity 11.Formed thus and have both the effect be convenient to feed liquor He realized foregoing invention object.

As shown in Figure 1, the curved transition in joint 23 of the second tube body 22 and tube body 21, what make liquid thus can be more smooth and easy to the input that turns to of Vertical direction by substantially horizontal.

As shown in Figure 1, tube body 21 is arranged on the central position of cavity 11, can ensure the uniformity of the liquid input in cavity 11 thus.

Wherein, gas-liquid ratio in cavity 11 is 1: 2, namely the input quantity of liquid ensures to input to 2/3rds of the volume of cavity 11, according to 0.618 golden section rule, / 3rd gas, 2/3rds liquid, pass through many experiments, this ratio is optimal proportion, can reach the effect of best elimination pulsation.

As shown in Figure 1, scarf 212 is formation of cutting sth. askew downwards towards fluid direction, makes liquid can derive towards fluid direction thus.

As shown in Figure 1, scarf 212 is 45 ° with the angle of horizontal plane, has both the effect of drain and enlarge active surface thus.

Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
