City's being laid on along the heat distribution pipe network of underground for Some Enterprises of having stable political situation needs to set isolating valve well and picks out many
Branch line simultaneously sets branching valve well, and these valve wells, which are mainly used in inspecting periodically for underground pipe network, to be safeguarded and breakdown maintenance.
But these valve wells, easily in the ponding of pit formation set by well head bottom, mainly there are several respects in ponding source：It is first
Rainwater is from well lid access wall, steam pipework itself seepage in addition, and some is exactly that the drain valve that sets of pipeline is discharged
Condensed water, ponding enters valve well development construction operation to workmen and brings inconvenience, and being both needed at present will using water pump
Well internal water accumulation is extracted out, had not only been wasted the energy but also had been influenceed conventional maintenance and the construction of pipe network.
Utility model content
To solve the above problems, the utility model is aimed to provide starts the dress that check valve lifts liquid using superheated vapor
Put.
To achieve the above object, the technical solution adopted in the utility model is as follows：One kind is started unidirectional using superheated vapor
Valve lifts the device of liquid, including part is immersed in the pit ponding of valve well shaft bottom for the closed vessel for accumulating liquid, institute
State the side wall upper part of container and connect the drain valve that heat distribution pipeline is provided with through air inlet pipe, the side wall upper part of the container be also associated with
The water inlet pipe that ponding is connected in the pit of shaft bottom, the water inlet pipe is serially connected with the first check valve, the free end of the water inlet pipe and well
Bottom pit bottom is arranged at intervals, and the container top is connected with vertical outlet pipe, and the outlet pipe extends downwardly into container closing
Plane is arranged at intervals on one end of inner chamber and container bottom, and the outlet pipe upper end is connected with the upper flume of open topped, described
Outlet pipe is serially connected with the second check valve, and the upper flume lower sidewall is connected with gutter by the road.
The outlet pipe upper end protrudes upward upper flume bottom surface.
The outlet pipe upper end is provided with the elbow for preventing that dust from entering.
The shape of the container is cylindrical shape, it would however also be possible to employ the other shapes such as square.
Further, the free end that the water inlet pipe is extended downwardly into ponding can install screen pack additional, prevent different in ponding
Thing is blocked by water inlet pipe is inhaled into.
Further, the utility model utilizes high-temperature condensation water and a small amount of height of the underground heat hydraulic piping through drain valve interval discharge
Steam is pressed, is changed according to closed cavity inside the container being immersed in the ponding of shaft bottom and the pressure difference of external atmosphere pressure, utilizes check valve
Unidirectional open function, alternately realize suction and the action of lifting liquid, the sustainable ponding by valve well shaft bottom is promoted to
Gutter is emitted into after tank, is that workmen provides a great convenience into valve well, both takes full advantage of prior art
The high-temperature condensation water of the directly outer row of middle heat distribution pipeline and the pressure and heat of high steam, avoid the energy caused using water pump again
Loss, it is simple and reliable for structure, beneficial to popularization, there is certain Social benefit and economic benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of utilization superheated vapor starts the device that check valve lifts liquid, including part is immersed in valve
It is used for the closed vessel 1 for accumulating liquid in the pit ponding of well shaft bottom, the side wall upper part of the container 1 connects heating power through air inlet pipe 4
The drain valve 5 that pipeline is provided with, the side wall upper part of the container 1 is also associated with the water inlet pipe 2 connected with ponding in the pit of shaft bottom, institute
State water inlet pipe 2 and be serially connected with the first check valve 3, the water inlet pipe 2 extends downwardly into free end and shaft bottom pit bottom interval in water
Set, the top of container 1 is connected with vertical outlet pipe 7, and the outlet pipe 7 extends downwardly into one end of the closing inner chamber of container 1
It is arranged at intervals with plane on the bottom of container 1, the upper end of outlet pipe 7 is connected with the upper flume 6 of open topped, the outlet pipe 7
The second check valve 8 is serially connected with, the lower sidewall of upper flume 6 is connected with gutter by the road.
The upper end of outlet pipe 7 protrudes upward the bottom surface of upper flume 6, prevents from being promoted to the water of upper flume 6 through on outlet pipe 7
Flow back at end.
The upper end of outlet pipe 7 is provided with the elbow for preventing that dust from entering, and elbow described in the present embodiment is elbow bend.
The free end for the free end that the water inlet pipe 2 is stretched into water is with the setting of shaft bottom pit bottom at intervals of 5cm.
The outlet pipe 7 is set at intervals of 0.5cm with plane on the bottom of container 1.
The shape of the container 1 is cylindrical shape, it would however also be possible to employ the other shapes such as square.
In the present embodiment, the drain valve 5 is disc type steam trap.
Further, the free end that the water inlet pipe 2 is extended downwardly into ponding can install screen pack additional, prevent different in ponding
Thing is inhaled into water inlet pipe 2 and blocked.
The utility model is in use, heat distribution pipeline outwards intermittently discharges the condensed water of high temperature through drain valve 5, while because hydrophobic
There is certain leakage vapour rate in valve 5, drain valve 5 can discharge a part of high temperature and high pressure steam simultaneously, and steam is together with condensed water through entering
Tracheae 4 enters the closing inner chamber of container 1, and closing inner chamber air pressure moment of container 1 rises, pressure force liquid in container 1 from
Outlet pipe 7 overcomes the Opening pressure of the second check valve 8 upwards, and upward liquid is flowed into after upper flume 6, and gutter is discharged into immediately.
The container 1 being immersed in ponding is cooled down quickly, and after steam and condensation water cooling, the air pressure inside container 1 is reduced to subatmospheric,
Now the ponding in shaft bottom overcomes the Opening pressure of the first check valve 3 to be inhaled into container 1 through water inlet pipe 2, and the inside and outside differential pressure of container 1 disappears
Lose and stop water inlet, with next lifting liquid working cycles can be entered.
The high-temperature condensation water intermittently discharged through drain valve 5 using underground heat hydraulic piping due to the utility model and a small amount of high pressure
Steam, changes according to the pressure difference for the inside closed cavity of container 1 and external atmosphere pressure being immersed in ponding, utilizes the unidirectional of check valve
Open function, alternately realizes suction and the action of lifting liquid, and the sustainable ponding by valve well shaft bottom is promoted to after upper flume
Gutter is emitted into, is that workmen provides a great convenience into valve well, has both taken full advantage of heating power in the prior art
The high-temperature condensation water of the directly outer row of pipeline and the pressure and heat of high steam, avoid the energy loss caused using water pump again,
It is simple and reliable for structure, beneficial to popularization, there is certain Social benefit and economic benefit.
