Abstract
The utility model discloses a plastic pipeline stop valve comprising a valve body, a valve plug, a valve plug hole, a water inlet, a water inlet channel, a water outlet channel and a water outlet. The plastic pipeline stop valve is characterized in that the valve plug hole is arranged in the valve body and internally provided with the valve plug; the water inlet, the water inlet pipeline, the water outlet and the water outlet pipeline are communicated with the valve plug hole, and are respectively arranged at two sides of the valve plug hole; and the upper edge wall and the lower edge wall of the water outlet channel are in inclined bending shape. The plastic pipeline stop valve has the advantages that the structure is simple, the water outlet channel is larger, and the flow velocity and the flow rate of water flow are both larger when the valve plug is opened.
Description
Technical field
The utility model relates to a kind of plastic pipe valve, relates in particular to a kind of stop valve that is used for plastic pipe.
Background technique
At present, common plastics waterway pipe all is the Push And Release that comes controlled water flow with pipe break valve, and the plastic pipe stop valve has been widely used in the various plastics waterway pipes especially now.But present existing plastic pipe stop valve is because the edge wall up and down of exhalant canal all is a rectangular shaped, water flow velocity when opening valve down to exhalant canal is too narrow and small and feasible is slower, existing plastic pipe stop valve as shown in Figure 2: valve body 11, spool 22, water intake 33, intake tunnel 44, exhalant canal 55, water outlet 66, exhalant canal top edge wall 77, exhalant canal lower limb wall 88.During use, when opening spool 22, current arrive intake tunnel 44 by water intake 33 earlier, current are again by exhalant canal 55, flow out from water outlet 66 at last, because exhalant canal top edge wall 77 and exhalant canal lower limb wall 88 all be rectangular shaped, so that make that the aperture efficiency of exhalant canal 55 is narrower and small, thereby it is all smaller to cause current to pass through the flow velocity and the flow of stop valve when the use stop valve.So be badly in need of to occur the big plastic pipe stop valve of a kind of exhalant canal in the market, to overcome in the plastic pipe stop valve industry current by the flow velocity and the equal smaller defect of flow of stop valve.
The model utility content
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of simple in structure, plastic pipe stop valve that exhalant canal is bigger is provided.
For solving the problems of the technologies described above, the utility model provides a kind of plastic pipe stop valve, comprises valve body, spool, spool bore, water intake, intake tunnel, exhalant canal, water outlet.
Be provided with spool bore in the described valve body, be provided with spool in the spool bore; Described water intake, intake tunnel and water outlet, exhalant canal communicate with spool bore, and are arranged at the both sides of spool bore respectively.
The top edge wall of described exhalant canal and the lower limb wall of exhalant canal are oblique bending.
The material of described valve body is a plastic materials.
During use, (spool upwards promotes when opening spool, spool bore is opened), current flow to water inlet of the present utility model from the connecting tube of the utility model one side head earlier, flow into intake tunnel again by water intake, flow into opened spool bore by intake tunnel again, flow into exhalant canal by spool bore again, flow into the connecting tube of the utility model opposite side termination at last from water outlet.When closing spool, because spool is in spool bore, the size of spool and the size of spool bore match, spool is when dropping to the bottom of spool bore, spool bore is blocked fully, and at this moment current are blocked this side at intake tunnel, so current just can't flow to the outlet passage opposite side by spool bore, when this situation of closing spool, the utility model plastic pipe stop valve just is in closing state.
Because the top edge wall of exhalant canal of the present utility model and the lower limb wall of exhalant canal all are designed to oblique bending structure, therefore overcome the less shortcoming of product water outlet of prior art, because model utility adopts technique scheme, therefore it is bigger to the utlity model has exhalant canal, all bigger advantage of the flow velocity of current and flow when opening spool.
Description of drawings
Fig. 1 is that master of the present utility model looks cross-sectional view;
Fig. 2 is that the master of the product of prior art looks cross-sectional view.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-valve body; The 2-spool; The 3-water intake; The 4-intake tunnel; 5-exhalant canal, 6-water outlet; The top edge wall of 7-exhalant canal; The lower limb wall of 8-exhalant canal; The 9-spool bore.
Embodiment
As shown in Figure 1, the utility model plastic pipe stop valve comprises valve body 1, spool 2, spool bore 9, water intake 3, intake tunnel 4, exhalant canal 5, water outlet 6.
Be provided with spool bore 9 in the described valve body 1, be provided with spool 2 in the spool bore 9; Described water intake 3, intake tunnel 4 and water outlet 6, exhalant canal 5 communicate with spool bore 9, and are arranged at the both sides of spool bore 9 respectively.
The top edge wall 7 of described exhalant canal 5 and the lower limb wall 8 of exhalant canal 5 are oblique bending.The material of described valve body 1 is a plastic materials.
During use, (spool 2 upwards promotes when opening spool 2, spool bore 9 is opened), current flow to water intake 3 of the present utility model from the connecting tube of the utility model one side head earlier, flow into intake tunnel 4 again by water intake 3, flow into opened spool bore 9 by intake tunnel 4 again, flow into exhalant canal 5 by spool bore 9 again, flow into the connecting tube of the utility model opposite side termination at last from water outlet 6.When closing spool 2, because spool 2 is in spool bore 9, the size of the size of spool 2 and spool bore 9 matches, spool 2 is when dropping to the bottom of spool bore 9, spool bore 9 is blocked fully, and at this moment current are blocked this side at intake tunnel 3, so current just can't flow to outlet passage 5 opposite sides by spool bore 9, when this situation of closing spool 2, the utility model plastic pipe stop valve just is in closing state.
Because the top edge wall 7 of exhalant canal of the present utility model and the lower limb wall 8 of exhalant canal all are designed to oblique bending structure, therefore overcome the less shortcoming of product water outlet of prior art, because model utility adopts technique scheme, therefore it is bigger to the utlity model has exhalant canal, all bigger advantage of the flow velocity of current and flow when opening spool.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
