Abstract
The utility model discloses a kind of direct current type polyethylene stop valve, comprise the stop valve body that polyethylene is made, described stop valve body is provided with straight-through runner vertically, sealed mouth is provided with in the middle part of described straight-through runner, described sealed mouth is communicated with the spool chamber of direct current channel side, be provided with spool in described spool chamber, described spool is controlled by handle, and it is axial arranged that described sealed mouth and spool favour direct current runner.The utility model improves valve body inner flow passage, adds flow section, thus reduces flow resistance.
Description
Technical field
The utility model relates to stop valve.
Background technique
PE pipeline has been widely used in rural drinking water safety engineering field at present, particularly small-bore PE tubing, pipe fitting and valve large usage quantity.This kind of engineering water supply pressure is general less, and pipeline is generally longer, therefore reduces the frictional head loss of pipe-line system, has great importance for raising water application efficiency, reduction operation energy consumption.
PE stop valve is mainly used on small-bore (below DN63mm) PF water supply line.As shown in Figure 1, traditional stop valve structure, comprise the stop valve body 1 of Three way type, stop valve body is provided with straight-through runner 11 vertically, is provided with horizontal direction sealed mouth 12, is provided with spool 2 and handle 3 perpendicular to straight-through runner in the middle part of straight-through runner, handle strip movable valve plug moves up and down, Open-close sealing mouth, when the sealing surface of spool and sealed mouth end face fit tightly, reaches cut-off current object.Mainly there is following drawback in tradition stop valve:
1) flow section is little.The size of spool stop surface is the size of flow section.
2) flowing has some setbacks.Runner in valve body is S shape, and flow resistance is large, and loss of head is larger.
Therefore, be necessary to develop the stop valve that a kind of loss of head is little, conveyance capacity is strong.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of direct current type polyethylene stop valve, and flow resistance is little, and flow is large, and conveyance capacity is strong
For solving the problems of the technologies described above, the utility model adopts following technological scheme: direct current type polyethylene stop valve, comprise the stop valve body that polyethylene is made, described stop valve body is provided with straight-through runner vertically, be provided with sealed mouth in the middle part of described straight-through runner, described sealed mouth is communicated with the spool chamber of direct current channel side, is provided with spool in described spool chamber, described spool is controlled by handle, and it is axial arranged that described sealed mouth and spool favour direct current runner.
Preferably, the angle of described sealed mouth and direct current runner axis is 45 degree.
Preferably, described sealed mouth and straight-through runner inner wall are that arc transition is connected.
Sealed mouth and spool are in tilted layout by the utility model, improve valve body inner flow passage, add flow section, thus reduce flow resistance, compare with traditional stop valve, and the resistance coefficient of Oblique Stop Valve declines 41%, and flow improves 30%.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is traditional stop valve structure schematic diagram;
Fig. 2 is stop valve of the present utility model structural representation when opening state;
Fig. 3 be stop valve of the present utility model in off position time structural representation.
Embodiment
As shown in Figures 2 and 3, direct current type polyethylene stop valve, comprise the stop valve body 1 that polyethylene is made, described stop valve body is provided with straight-through runner 11 vertically, sealed mouth 12 is provided with in the middle part of described straight-through runner, described sealed mouth side is provided with spool 2, and described spool is controlled by handle 3, and it is axial arranged that described sealed mouth and spool favour direct current runner.The angle of described sealed mouth and direct current runner axis is 45 degree.Described sealed mouth and straight-through runner inner wall are that arc transition is connected 13.
The sealing surface (flow section) of tradition stop valve is arranged in horizontal direction, and runner perpendicular to pipeline axially.During valve wide open, current to do in valve body 2 times 90 degree turn to, therefore loss of head is larger.When head is less in managing, the valve downstream water yield can be caused to reduce.Therefore, the utility model considers spool and sealed mouth to be in tilted layout, and adjustment water (flow) direction additionally by level and smooth runner, thus reaches the object reducing loss of head, augmented flow.
