example 1
As shown in fig. 1, the opening and closing hydraulic system for the city water valve of the embodiment includes: an oil cylinder 1; one end of the emergency loop is connected with the oil cylinder 1, and the other end of the emergency loop is connected with the oil tank 2; the emergency circuit comprises: a first electromagnetic directional valve 3; a manual pump 4; a first check valve 5; a manual valve 6; the manual pump 4 is arranged in series with the first one-way valve 5, the series loop is arranged in parallel with the manual valve 6, the parallel loop is connected with one end of the first electromagnetic reversing valve 3, the other end of the first electromagnetic reversing valve 3 is connected with the oil cylinder 1, the inlet of the manual pump 4 is connected with the oil tank 2, and the outlet of the manual pump is connected with the first one-way valve 5.
The emergency circuit is arranged in a disconnection manner when the first electromagnetic directional valve 3 is powered on, and the emergency circuit is arranged in a connection manner when the first electromagnetic directional valve 3 is powered off. When the first electromagnetic directional valve 3 is electrified, the circuit is broken. When the first electromagnetic directional valve 3 is in power failure, the first electromagnetic directional valve is conducted, and the emergency loop is communicated. In this embodiment, the first electromagnetic directional valve 3 is a two-position two-way electromagnetic directional valve.
The embodiment further comprises a one-way throttle valve 10, wherein one end of the one-way throttle valve 10 is connected with the first electromagnetic directional valve 3, and the other end of the one-way throttle valve 10 is connected with a parallel loop of the manual pump 4, the first one-way valve 5 and the manual valve 6. The flow direction of the first one-way valve 5 is from the manual pump 4 to the first electromagnetic directional valve 3.
In this embodiment, the chamber in which the piston rod of the oil cylinder 1 is located is a rod chamber, and the other chamber is a rodless chamber. One end of the emergency loop is connected with the rod cavity, and the other end of the emergency loop is connected with the oil tank 2. One end of the emergency loop is connected with the rod cavity, namely one end of the first electromagnetic directional valve 3 is connected with the rod cavity. One end of the first electromagnetic directional valve 3 is connected with the rod cavity, and the other end of the first electromagnetic directional valve is connected with a parallel loop of the manual pump 4, the first one-way valve 5 and the manual valve 6.
The embodiment further comprises a main loop, the main loop comprises a second electromagnetic directional valve 7, and two outlets of the second electromagnetic directional valve 7 are respectively connected with the rod cavity and the rodless cavity. The embodiment further comprises a balance valve 8, and the balance valve 8 is arranged on a loop of the second electromagnetic directional valve 7 and the oil cylinder 1. The balance valve 8 is a stacked balance valve 8, two ports of the stacked balance valve 8 are respectively connected with the rod cavity and the second electromagnetic directional valve 7, and a pilot port of the stacked balance valve 8 is connected with a loop of the second electromagnetic directional valve 7 leading to the rodless cavity. The opening pressure of the balance valve 8 is larger than the total gravity of the water valve and the piston of the oil cylinder 1. The second electromagnetic directional valve 7 is a three-position four-way electromagnetic directional valve.
When the water valve is used, the opening and closing of the water valve are realized through the main loop under the condition that the commercial power is normal. At this time, the first electromagnetic directional valve 3 is powered on, the emergency loop is in a disconnected state, and the emergency loop does not work. The second electromagnetic directional valve 7 is operated in different power-on and power-off directions, so that oil is fed into the rod cavity and returned into the rodless cavity, and the water valve is opened; the rodless cavity is filled with oil, the rod cavity is filled with oil, and the water valve is closed. The balancing valve 8 serves to prevent the uncontrolled falling of the water valve.
The utility model discloses the focus lies in, the commercial power is under the condition of losing the electricity, opening and close of water valve door. Under the condition of abnormal power supply and power loss of the mains supply, the first electromagnetic directional valve 3 is conducted in a power loss mode, and the emergency loop is conducted. Firstly, under the condition of abnormal power supply and power loss of the commercial power, the water valve is required to be closed. At this time, the manual pump 4 is not operated. The main circuit is non-conductive due to the balance valve 8 of the main circuit. The oil in the rod chamber passes through the first electromagnetic directional valve 3 which is conducted, namely, the oil in the rod chamber flows from the emergency loop. The oil in the rod chamber can be returned to the oil tank 2 by opening the manual valve 6. Thus, the water valve falls closed. At this time, the check throttle valve 10 plays a role of controlling the oil speed.
If the water valve needs to be opened under the conditions of abnormal power supply and power loss of the mains supply, the manual valve 6 needs to be closed, the manual pump 4 is manually operated, oil liquid passes through the manual pump 4, the first one-way valve 5, the one-way throttle valve 10 and the first electromagnetic reversing valve 3 from the oil tank 2 and enters the rod cavity, and therefore the piston pulls the water valve to be opened.
