Background technology
Pit shaft and well seat are after connection at present, and the water in pit shaft flows in well seat, from the delivery port of well seat, flow out; Owing to being also provided with a plurality of water inlets on well seat, make in this process, by the water flowing out in pit shaft, can impact the water that well seat water inlet flows out, both form one impact force, thereby cause the delivery port from well seat that these current can not be effectively unimpeded to flow out.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, water impact is little and guarantee current unimpeded make the plastic inspection well that current are more unimpeded.
In order to achieve the above object, designed a kind of of the utility model makes the plastic inspection well that current are more unimpeded, it comprises well seat body and spirally-guided bar, well seat body is one-time formed, the upper end of well seat body is provided with a birdsmouth, on the inwall of birdsmouth, be provided with groove, make the upper end of birdsmouth inwall form a cushion cap; On well seat body, be at least provided with a water inlet pipe, be also provided with an outlet pipe, one end of spirally-guided bar is fixedly installed on the bottom of cushion cap, and the other end of spirally-guided bar causes the port of outlet pipe.
As preferably, the width of cushion cap is 0.5~1.5cm.
As preferably, on well seat body, be laterally provided with two water inlet pipes, and the central axes of these two water inlet pipes; On well seat body, be vertically provided with a water inlet pipe and an outlet pipe, and the central axis of outlet pipe is lower than the central axis of water inlet pipe; Well seat body vertically arranges the central axis of water inlet pipe of water inlet pipe and horizontally set all in same level position.
According to above-described a kind of plastic inspection well that current are more unimpeded that makes, during use, after pit shaft is connected with well seat body, owing to being provided with spirally-guided bar in well seat body, from the water flowing out in pit shaft, by spirally-guided bar, drain into the outlet pipe place of well seat body, reduced the impact force between the water that in water from flowing out in pit shaft and well seat body, water inlet pipe goes out to flow out, guarantee that the water in well seat body can unimpeded flowing out from outlet pipe.Therefore, it has the features such as simple in structure, reasonable in design and easy to use.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the present embodiment is described a kind ofly makes the plastic inspection well that current are more unimpeded, it comprises well seat body 1 and spirally-guided bar 2, well seat body 1 is one-time formed, the upper end of well seat body 1 is provided with a birdsmouth, on the inwall of birdsmouth, be provided with groove 3, make the upper end of birdsmouth inwall form a cushion cap; Well seat body 1 is provided with a water inlet pipe 4 and an outlet pipe 5, and one end of spirally-guided bar 2 is fixedly installed on the bottom of cushion cap, and the other end of spirally-guided bar 2 causes the port of outlet pipe 5.
