Detailed Description
The following describes the present invention in further detail with reference to specific examples:
As shown in figure 1, the floating ball type two-way stop valve control system is applied to a vacuum well and is used for pumping out and discharging sewage discharged into the vacuum well, and the structure of the floating ball type two-way stop valve control system mainly comprises a drainage pipeline 1, a vacuum valve 4 arranged on the drainage pipeline 1 and a two-way stop floating ball 5 for controlling the opening and closing of the vacuum valve 4.
The drainage pipeline 1 is of a 7-shaped structure and comprises a water suction pipeline 2 arranged in the vertical direction and a negative pressure pipeline 3 arranged in the horizontal direction, the water suction pipeline 2 is used for extending downwards to the lower part of a vacuum well during installation so as to achieve the purpose of water suction, and the vacuum valve 4 is arranged between the water suction pipeline 2 and the negative pressure pipeline 3 and is used for connecting the water suction pipeline 2 and the negative pressure pipeline 3.
The bidirectional stop floating ball 5 is of a sealing structure, a bidirectional stop valve 6 is arranged in the bidirectional stop floating ball 6, the bidirectional stop valve 6 comprises a shell 7, a first end cover 10 and a second end cover 11 which are installed at the upper end and the lower end of the shell 7 in a nested matching mode, and a gravity steel ball 9 arranged in the shell 7, a cavity 8 with an 8-shaped cross section in the vertical direction is arranged in the shell 7, the gravity steel ball 9 is arranged in the cavity 8 and can move in the cavity 8, the gravity steel ball 9 is used for blocking an atmospheric air inlet or a negative pressure air inlet in different states, therefore, a plane sealing ring 12 is nested on one side end face of the first end cover 10 and the second end cover 11 in the cavity 8, sealing performance of the blocking is effectively guaranteed, a vacuum valve connecting port 13 communicated with the cavity 8 is arranged on the side wall of the shell 7, an atmospheric air inlet 14 communicated with the cavity 8 is arranged on the first end cover 10, a negative pressure air inlet 15 communicated with the cavity 8 is arranged on the second end cover 11, the vacuum valve connecting port 13 is communicated with the vacuum valve 4 through a valve body 16, the atmospheric air inlet 14 is connected with the atmospheric air inlet 17, and a negative pressure switch 19 is further communicated with the negative pressure air inlet 18 through a negative pressure pipeline 19 arranged on one end far away from the atmospheric air inlet 3.
As a further optimization of this embodiment, since the lifting of the liquid level in the vacuum well affects the gas pressure inside the water pumping pipeline 2, the sidewall of the water pumping pipeline 2 is connected with the air release pipe 20, one end of the air release pipe 20, which is biased towards the water pumping pipeline 2, extends upwards along the vertical direction, and one end, which is far away from the water pumping pipeline 2, is provided with the air release regulating valve 21, and since the bidirectional stop valve 6 needs to be arranged at the end of the vacuum well, the air intake pipe 17, the negative pressure intake pipe 18 and the valve body breather pipe 16 need to extend downwards, in order to prevent the arrangement of the pipelines from being too disordered, the pipelines are attached to the air release pipe 20, and the pipelines are fixedly connected by the buckle, the overturning of the bidirectional stop floating ball 5 cannot be affected when the buckle is connected, and in order to facilitate the connection of the buckle, the air release pipe 20 arranged along the vertical direction can adopt a hard structure.
When the vacuum well is at a low water level, the bidirectional stop floating ball 5 is vertically downward, the state is shown in fig. 1, the state of the bidirectional stop valve 6 in the bidirectional stop floating ball 5 is shown in fig. 2, the gravity steel ball 9 falls on the bottom of the shell 7 under the action of gravity to seal the negative pressure air inlet 15, the sealing performance of the sealing is ensured due to the action of the plane sealing ring 12, the air inlet 14 is communicated with the vacuum valve connecting port 13, the vacuum valve 4 is closed, and the vacuum valve 4 belongs to the prior art, and mainly because the action of the atmosphere can lead the internal diaphragm to be rapidly deformed to be closed, the invention will not further describe the detailed structure in the vacuum valve 4.
When the vacuum well is at a high water level, the bidirectional stop floating ball 5 is held down and can rotate 180 degrees, the state is shown in fig. 4, the bidirectional stop valve 6 can also rotate 180 degrees at the moment, the state is opposite to that of fig. 2, the gravity steel ball 9 can drop to the bottom under the action of gravity to seal the air inlet 14, the sealing performance of the sealing is ensured due to the action of the plane sealing ring 12, the negative pressure air inlet 15 is communicated with the vacuum valve connecting port 13 at the moment, the vacuum valve 4 is opened, and the internal diaphragm can be rapidly deformed and contracted mainly due to the action of negative pressure gas, so that the vacuum well belongs to the prior art and is not described in more detail.
Meanwhile, in order to consider the influence of extreme weather, such as heavy rain, water in the vacuum well overflows, water is easy to enter the air inlet pipe 17, and the normal opening and closing of the vacuum valve 4 are influenced at the moment, so that the liquid level switch 19 is arranged at the end part of the air inlet pipe 17, and before the water in the vacuum well overflows, the liquid level switch 19 can automatically close the bidirectional stop valve 6, namely, the air inlet 14 is blocked, the negative pressure air inlet 15 is communicated with the vacuum valve connecting port 13, and the normal operation of the vacuum valve 4 is ensured.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement the same according to the content of the present invention, and are not intended to limit the scope of the present invention.
