Abstract

The utility model discloses a drainage valve base. The drainage valve base comprises a base body, wherein the base body is provided with a drainage channel, and the drainage channel is provided with a drainage inlet and a drainage outlet. The drainage valve base is characterized in that the reducing portion and the arc-shaped guiding portion are arranged in the drainage channel, one end of the arc-shaped guiding portion extends to the position of the drainage inlet, and the other end of the arc-shaped guiding portion is connected with the reducing portion. The drainage valve base has the advantages that the reducing portion is arranged in the drainage channel to enable the arc-shaped guiding portion to meet the water flow characteristics and enable water passing the base to flow along the arc surface of the arc-shaped guiding portion to the greatest extent, accordingly bubbles are not produced, the drainage channel is full of the water, and the drainage effect is maximized to improve the drainage speed of a drainage valve.

Description

A kind of drainage valve base
Technical field
The utility model relates to a kind of drainage valve base.
Background technique
Existing drainage valve base, its drain opening place is straight-tube shape to downward-extension with the oblique angle transition or from drain opening, when drain valve is opened, current flow out through drain opening, because its crossover position is not done certain adjustment, current can produce bubble at the drain opening place when the downward draining of drain opening, this bubble can take the certain space of drain opening, make drainage rates reduce.
The model utility content
The utility model provides a kind of drainage valve base, and it has overcome the existing deficiency of background technique.The technological scheme that adopts that the utility model solves its technical problem is: a kind of drainage valve base, it comprises a base body (10), this base body (10) is provided with a drainage channel (20), this drainage channel (20) has a drainage inlet (30) and a drain outlet (40), it is characterized in that: be provided with a diameter reducing part (50) and an arc guide portion (60) in described drainage channel (20), one of this arc guide portion (60) end extends to drainage inlet (30) and locates, and the other end of arc guide portion (60) is connected with diameter reducing part (50).
Among one preferred embodiment: drainage inlet (30) locates to be provided with a sealing face (31), this sealing face (31) and tangent connection of arc guide portion (60).
Among one preferred embodiment: described diameter reducing part (50) and tangent connection of arc guide portion (60).
Among one preferred embodiment: wall facing directly or inclined-plane for annular within described diameter reducing part (50).
Among one preferred embodiment: described sealing face (31) highest point diameter is D1, and diameter reducing part (50) is D2 with the joint diameter of arc guide portion (60), and D1〉D2.
Among one preferred embodiment: the difference of D1 and D2 is greater than 7 millimeters.
Among one preferred embodiment: also comprise that one connects the flow-off (70) of drainage channel, described diameter reducing part (50) extends to below the edge, bottom of flow-off (70).
Among one preferred embodiment: described diameter reducing part (50) extends to drain outlet (40) and locates.
Among one preferred embodiment: described diameter reducing part (50) is one-body molded with arc guide portion (60).
Among one preferred embodiment: described diameter reducing part (50), arc guide portion (60) and base body (10) are one-body molded.
The technical program is compared with background technique, and it has following advantage:
1. in drainage channel, diameter reducing part is set so that the arc guide portion is more pressed close to the characteristic of current, while making current pass through base, the cambered surface along the arc guide portion is mobile as far as possible, thereby does not produce bubble, allows drainage channel fill up fully water, make drain efficiency maximization, to increase the drainage rate of drain valve.
2. the residing plane of drainage inlet is connected with the arc guide portion is tangent, makes the current drainage channel of more fitting flow out downwards.
3.D1 with the difference of D2,, greater than 7 millimeters, make the drainage efficiency of drainage channel higher.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the overall schematic of a kind of drainage valve base of a preferred embodiment.
Fig. 2 has illustrated the cross-sectional schematic of a kind of drainage valve base of a preferred embodiment.
Embodiment
Please refer to Fig. 1 to Fig. 2, an a kind of preferred embodiment of drainage valve base, described a kind of drainage valve base, it comprises a base body 10.
This base body 10 is provided with a drainage channel 20, and this drainage channel 20 has a drainage inlet 30 and a drain outlet 40.This base body also is provided with the flow-off 70 of a connection drainage channel.
Be provided with a diameter reducing part 50 and an arc guide portion 60 in described drainage channel 20, one of this arc guide portion 60 end extends to drainage inlet 30 places, and the other end of arc guide portion 60 is connected with diameter reducing part 50.
In the present embodiment, drainage inlet 30 places are provided with a sealing face 31, and this sealing face 31 is connected with arc guide portion 60 is tangent.Make the current drainage channel of more fitting flow out downwards.
In the present embodiment, described diameter reducing part 50 is connected with arc guide portion 60 is tangent.Make the current drainage channel of more fitting flow out downwards.
In the present embodiment, wall facing directly or inclined-plane for annular within described diameter reducing part 50.
In the present embodiment, described sealing face (31) highest point diameter is D1, and diameter reducing part 50 is D2 with the joint diameter of arc guide portion 60, and D1〉D2.Best, the difference of D1 and D2, greater than 7 millimeters, makes the drainage efficiency of drainage channel higher.
In the present embodiment, described diameter reducing part 50 extends to below the edge, bottom of flow-off 70.Perhaps, as required, described diameter reducing part 50 can be extended to drain outlet 40 places.
