Abstract
The utility model discloses a jet flow valve of a high suction stroke ejector. The jet flow valve of the high suction stroke ejector comprises a valve body, wherein a water inlet channel, a backflow channel and a water outlet channel are arranged in the valve body. The water inlet channel and the backflow channel converge at the position of a lower end of the water outlet channel, the water inlet channel is communicated with the water outlet channel, the lower end of the water inlet channel is connected with a lower end of the valve body, an upper end of the water outlet channel is connected with an upper end of the valve body, and the backflow channel is of a U-shaped pipe structure. The jet flow valve of the high suction stroke ejector solves the problem that an ejector has certain limitation on the depth of low-position medium, enhances a suction stroke of the ejector, and simultaneously ensures working quality.
Description
Technical field
The utility model relates to a kind of water pump field, especially relates to a kind of fluid valve that is applied to the sparger in water pump field.
Background technique
Sparger is a kind of uneven principle of utilizing pressure with the medium transport of the lower a kind of equipment to eminence, sparger is widely used in treegarden irrigation and tall building water etc. at present, this traditional sparger is in daily use, rigid condition restriction due to himself fluid valve structure, make the power resources that consumes also larger, inhale simultaneously journey lower, cause work not carry out smoothly, normal use has been brought unnecessary trouble.
Summary of the invention
For the deficiencies in the prior art, the utility model discloses a kind of fluid valve of high suction depth sparger, solved the certain limitation of sparger to the lower media depth, increased the suction journey of sparger, the quality when having guaranteed simultaneously work.
In order to realize above-mentioned effect, the utility model adopts following technological scheme:
A kind of fluid valve of high suction depth sparger, comprise valve body, be provided with intake tunnel, return flow line and exhalant canal in described valve body, described intake tunnel and return flow line are converged at the lower end mouth place of exhalant canal, and communicate with exhalant canal, the lower end mouth of described intake tunnel and the lower end mouth of valve body are joined, and the upper end-hole of exhalant canal and the upper end-hole of valve body are joined, and described return flow line is the U-shaped tubular construction.
Further, described intake tunnel and return flow line are not less than the cross-section area of exhalant canal lower channel mouth at the cross-section area of the lower end mouth concourse of exhalant canal.
Further, the cross-section area at upper pipes road junction, described return flow line is identical with the cross-section area of exhalant canal lower channel mouth.
Further, the cross-section area at upper pipes road junction, described return flow line is identical with the cross-section area of intake tunnel lower channel mouth.
Technique scheme of the present utility model has the following advantages compared to existing technology:
The fluid valve of a kind of high suction depth sparger described in the utility model, due to the structure of having improved fluid valve, increased the return flow line, the return flow line can effectively utilize the water that flogs a dead horse again to reflux, make its twice work doing, make the jet flow intensity enhancing of sparger, reduced the restriction of sparger to the lower medium, eliminate to a certain extent the phenomenon of sparger traffic overload, strengthened utilization efficiency in routine duties.
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment of the utility model also by reference to the accompanying drawings.
Description of drawings
Fig. 1 is the structure principle chart of the fluid valve of a kind of high suction depth sparger of the utility model;
In figure, 1 is valve body, and 2 is intake tunnel, and 3 is the return flow line, and 4 is exhalant canal.
Embodiment
Figure 1 shows that the fluid valve of a kind of high suction depth sparger described in the utility model, comprise valve body 1, in order to solve sparger to the certain limitation of lower media depth, increase the suction journey of sparger, quality when guaranteeing work simultaneously, be provided with intake tunnel 2 in described valve body 1, return flow line 3 and exhalant canal 4, described intake tunnel 2 and return flow line 3 are converged at the lower end mouth place of exhalant canal 4, and communicate with exhalant canal 4, the lower end mouth of the lower end mouth of described intake tunnel 2 and valve body 1 is joined, the upper end-hole of the upper end-hole of exhalant canal 4 and valve body 1 is joined, described return flow line 3 is the U-shaped tubular construction.
In the present embodiment, due to the structure of having improved fluid valve, increased return flow line 3, return flow line 3 can effectively utilize the water that flogs a dead horse again to reflux, make its twice work doing, make the jet flow intensity enhancing of sparger, reduced the restriction of sparger to the lower medium, eliminate to a certain extent the phenomenon of sparger traffic overload, strengthened utilization efficiency in routine duties.
Described intake tunnel 2 is not less than the cross-section area of exhalant canal 4 lower channel mouths with return flow line 3 at the cross-section area of the lower end mouth concourse of exhalant canal 4, the cross-section area at 3 upper pipes road junctions, described return flow line is identical with the cross-section area of exhalant canal 4 lower channel mouths, and the cross-section area at 3 upper pipes road junctions, described return flow line is identical with the cross-section area of intake tunnel lower end 2 pipeline opening.
