Technical Field

The invention relates to the technical field of BIM engineering control, in particular to BIM engineering terminal heating control equipment.

Background

The BIM is a building information model, and the BIM has the functions of enabling engineering project information to be fully shared and transmitted in a lossless manner in the whole process of planning, designing, constructing, operating and maintaining, enabling engineering technology and management personnel to efficiently and correctly understand and respond to various building information, providing a solid foundation for cooperative work of multiple parties, and providing a reliable basis for decision of each party in the whole life cycle of the construction project from concept to removal; when BIM technique is applied to resident heating pipe network field, need control and monitoring each user terminal, and the key of technical implementation often is on the terminal valve, the terminal valve often appears leaking the condition in the in-service use, prior art can close the terminal valve when the terminal valve leaks, nevertheless can't judge whether the terminal valve need be closed according to the size of leaking the volume, thereby the terminal valve leaks the volume less relatively, the terminal valve can't close also can't inform the staff to maintain, and then causes the influence to the surrounding environment.

The BIM engineering terminal warm control valve comprises an electric cabinet, an upper cover, a motor, a hand wheel, an electrifying structure, a temperature sensor, an auxiliary passage, a bottom cover, a left valve body, a self-locking spring, a piston, an upright rod, a wireless communication module, a cross rod, a control module, a valve ball, a valve rod, a connecting block, a right valve body, a sealing seat, a check ring, a compensation spring, a sealing ring, a first magnetic block, a second magnetic block, a rotating groove, a trigger switch and an upper valve body; the upper valve body comprises a supporting part, an upper cover part and a sealing part, an auxiliary passage is arranged in the upper valve body, and the middle part of the upper cover is provided with the round cover; the technical scheme is provided with a self-locking structure to realize self-locking of water leakage; the operation part and the bottom surface are isolated from the heat source as much as possible, so that scalding is prevented; the temperature sensor of the sampling temperature measuring point is arranged on the auxiliary passage, and is protected by the shade with the upper cover, and the flow of the auxiliary passage is small, thereby being more beneficial to the sampling detection of the water temperature; however, when the water hammer phenomenon is generated inside the heating pipe, the flow rate of partial water flow is increased, so that when the water flow reaches one end of the auxiliary passage, the water pressures at the two ends of the auxiliary passage are changed, the terminal valve is not leaked and the terminal valve is closed, and meanwhile, when the leakage amount of the terminal valve is relatively small, the water pressure difference at the two ends of the auxiliary passage is not obvious, the terminal valve cannot be closed or the terminal valve cannot be prompted to notify, and the limitation of the scheme is further caused.

In view of this, in order to overcome the above technical problems, the present invention provides a BIM engineering terminal warming control device, which solves the above technical problems.

when the terminal valve is in work, although the terminal valve can be closed when the terminal valve leaks in the prior art, whether the terminal valve needs to be closed or not cannot be judged according to the leakage amount, so that when the leakage amount of the terminal valve is relatively small, the terminal valve cannot be closed or cannot be notified to a worker for maintenance, and further the surrounding environment is influenced;

therefore, when the water hammer phenomenon is generated in the heating pipe in the use process, the water flow with the increased flow speed contacts one end of the auxiliary channel at first, the pressure at one end of the auxiliary channel is increased, and the magnet block deflects towards one end with smaller pressure under the pressure difference at the two ends of the auxiliary channel; the water flow with the increased flow velocity flows in the terminal valve, the water flow with the increased flow velocity is contacted with the two ends of the auxiliary channel, and the magnet block stops moving at the moment; the water flow with the increased flow velocity continuously flows forwards, so that the end, which is firstly contacted with the water flow with the increased flow velocity, of the auxiliary channel is not contacted with the water flow with the increased flow velocity, the pressure at the two ends of the auxiliary channel is opposite to that at the moment, the magnet block moves towards the end with the relatively smaller pressure, and the magnet block returns to the original position; when the leakage amount of the terminal valve is small, the pressure difference between two ends of the auxiliary channel is not obvious, so that the magnet block cannot be pushed by water flow in the auxiliary channel, the water flow leaked by the terminal valve enters the first cavity, the water flow sensor in the second sensor detects that water flow exists in the cavity along with the increase of water flow, the second sensor transmits information to the controller through the signal transmission line, the terminal valve is still opened at the moment, the controller transmits the information to a worker, the worker goes to the position of the terminal valve to overhaul the terminal valve, and the worker extracts the through hole plug to remove the water flow in the first cavity when overhauling the worker; when the leakage amount of the terminal valve is relatively large, the pressure difference between two ends of the auxiliary channel is relatively large and exists all the time, the position of the magnet block moves in the auxiliary channel, so that the first sensor transmits the information of the magnet position deviation to the controller, the controller controls the motor to close the terminal valve and transmit the information to workers, and the workers rush to the site for maintenance; after the maintenance is finished, the worker pulls out the through hole plug, so that water in the first cavity is discharged;

according to the invention, when the position change of the magnet block is transmitted to the controller when the water hammer phenomenon is generated in the heating pipe through the first sensor, the terminal valve is not closed by the controller, so that the aim of preventing the terminal valve from being closed by the controller by mistake when the water hammer phenomenon is generated is achieved, and the use effect of the terminal valve is ensured; when the leakage amount of the terminal valve is small, the sensor is used for detecting, the controller does not close the terminal valve and informs workers of overhauling, and therefore the normal use of heating of a user can be guaranteed, and the normal work of the terminal valve can be influenced by leaked water.

when the magnetic sensor works, the magnet block and the magnet strip are mutually attracted in an initial state, the magnet strip generates tension on the elastic rope, and the magnet strip transmits the tension to the first sensor through the elastic rope; when the magnet block is pushed by water flow in the auxiliary channel, the interaction force between the magnet strip and the magnet block disappears, so that the tensile force of the magnet strip on the connecting rope is reduced, the tensile force transmitted to the first sensor by the magnet strip through the connecting rope is also reduced, the first sensor transmits a signal of tensile force change to the controller, and the controller controls the motor to close the terminal valve; the position of the first sensor is higher than that of the valve, so that when the valve leaks, leaked water flow cannot contact the first sensor, and the first sensor is prevented from being damaged due to water flow erosion;

according to the invention, through the transmission among the magnet block, the magnet strip, the elastic rope and the first sensor and the matching of the position of the first sensor higher than the position of the valve, the first sensor is prevented from being corroded and damaged by water flow leaked from the terminal valve when the first sensor normally operates, the service life of the first sensor is ensured, and the service life of the sensor is further prolonged.

when the water-saving type water-saving device works, the second supporting block 8 pulls out the through hole plug 12, at the moment, the through hole plug 12 floats on the water surface, water in the first cavity 2 is discharged through the through hole groove 11, water in the first cavity 2 is collected to the through hole groove 11, and meanwhile, water leaked from the end valve continuously flows to the first cavity 2, so that the fluctuation sliding rods 21 generated on the water surface in the first cavity 2 are positioned on two sides of the second supporting block 8, when the second supporting block 8 floats on the water surface, water flowing down from the valve 4 is prevented from falling onto the second sensor 81, and the service life of the second sensor 81 is further ensured; when the staff repaired the terminal valve, terminal valve department stops leaking, thereby remaining water continues to discharge in cavity 2, rivers in cavity 2 when passing through-hole groove 11, the rivers velocity of flow that is close to through-hole groove 11 cell wall is relatively slow, the velocity of flow of rivers that through-hole groove 11 central point put is relatively fast, thereby form the negative pressure in the middle of rivers, and then rivers flow to the negative pressure zone on every side and form the swirl, through-hole stopper 12 is attracted by the swirl this moment, make the position of through-hole stopper 12 be perpendicular to through-hole groove 11 all the time at cavity 2 in-process that rivers were discharged, prevent the position skew of through-hole stopper 12, thereby through-hole stopper 12 stops through-hole groove 11 when the water in cavity 2 was all discharged, the manual mesh of getting rid of cavity 2 water of the staff has been reduced, the maintenance degree of difficulty of staff in narrow and small space has been reduced once more.

The specific working process is as follows:

therefore, in the use process of the invention, when the water hammer phenomenon is generated in the heating pipe, the water flow with the increased flow speed contacts with one end of the auxiliary channel 6 at first, the pressure at one end of the auxiliary channel 6 is increased, and the magnet block 61 deflects towards the end with the smaller pressure under the pressure difference at the two ends of the auxiliary channel 6; as the water flow with increased flow rate flows in the end valve, the water flow with increased flow rate contacts with both ends of the auxiliary channel 6, and at this time, the magnet block 61 stops moving; the water flow with the increased flow velocity continues to flow forwards, so that the end of the auxiliary channel 6, which is firstly contacted with the water flow with the increased flow velocity, is not contacted with the water flow with the increased flow velocity, the pressure at the two ends of the auxiliary channel 6 is opposite to that at the moment, the magnet block 61 moves towards the end with the relatively smaller pressure, the magnet block 61 returns to the original position, in the moving process of the magnet block 61, the first sensor 71 transmits the information of the movement of the magnet block 61 to the controller through a signal transmission line, so that the controller judges the information, and at the moment, the controller does not control the motor 5 to rotate to close the terminal valve; when the leakage amount of the terminal valve is small, the pressure difference between two ends of the auxiliary channel 6 is not obvious, so that the magnet block 61 cannot be pushed by water flow in the auxiliary channel 6, the water flow leaked by the terminal valve enters the first cavity 2, the water flow sensor in the second sensor 81 detects that water flow exists in the cavity along with the increase of water flow, the second sensor 81 transmits information to the controller through a signal transmission line, the terminal valve is still opened at the moment, the controller transmits the information to a worker, the worker goes to the position of the terminal valve to overhaul the terminal valve, and the worker pulls out the through hole plug 12 to remove the water flow in the first cavity 2 during overhauling; when the leakage amount of the terminal valve is relatively large, the pressure difference between two ends of the auxiliary channel 6 is relatively large and exists all the time, at the moment, the position of the magnet block 61 moves in the auxiliary channel 6, so that the first sensor 71 transmits the information of the position deviation of the magnet to the controller, the controller controls the motor 5 to close the terminal valve and transmit the information to workers, and the workers rush to the site for maintenance; after the maintenance is finished, the worker pulls out the through hole plug 12, so that water in the first cavity 2 is discharged; the magnet block 61 and the magnet bar 72 are attracted to each other in the initial state, at this time, the magnet bar 72 generates a tensile force on the elastic rope 73, and the magnet bar 72 transmits the tensile force to the first sensor 71 through the elastic rope 73; when the magnet block 61 is pushed by the water flow in the auxiliary channel 6, the interaction force between the magnet strip 72 and the magnet block 61 disappears, so that the tensile force of the magnet strip 72 on the connecting rope 82 is reduced, the tensile force of the magnet strip 72 transmitted to the first sensor 71 through the connecting rope 82 is also reduced, the first sensor 71 transmits the signal of the change of the tensile force to the controller, and the controller controls the motor 5 to close the terminal valve; the position of the first sensor 71 is higher than that of the valve 4, so that when the valve 4 leaks, leaked water cannot contact the first sensor 71, and the first sensor 71 is prevented from being damaged due to water erosion; under the condition that the leakage amount of the terminal valve is small, water leaked from the valve 4 flows on the inner shell 3 and then flows to the bottom of the first cavity 2 from the side surface of the inner shell 3, and the second supporting block 8 and the second sensor 81 are positioned in the center of the bottom surface of the first cavity 2, so that the falling water cannot contact with the second sensor 81; with the increase of the water flow in the first cavity 2, the second supporting block 8 floats on the water surface in the first cavity 2, the second sensor 81 is positioned at the upper end of the second supporting block 8, so that the second sensor 81 cannot contact the water surface, with the increase of the water flow in the first cavity 2, the position of the second supporting block 8 continues to rise until the connecting rope 82 is straightened, at the moment, the tension sensor in the second sensor 81 is under the tension of the connecting rope 82, and then the second sensor 81 transmits a tension signal to the controller; the water flow in the auxiliary channel 6 pushes the magnet block 61 under the driving of the pressure difference between the two ends of the auxiliary channel 6, so that the elastic rope 73 on one side of the magnet block 61 is stretched to move towards the side with low pressure of the auxiliary channel 6, after the magnet block 61 is separated from the interaction of the magnet strip 72, the magnet block 61 is contacted with the end surface of the annular groove 62, and the magnet block 61 cannot move continuously; the magnet block 61 is prevented from moving too far under the action of water flow thrust or sliding out of the auxiliary channel 6, so that the use effect of the water-jet type magnetic separator is ensured; after the terminal valve is maintained by a worker, the worker opens the terminal valve through the controller, so that the pressures at the two ends of the terminal valve are equal, the elastic rope 73 pulls the magnet block 61 until the elastic rope 73 is restored to the original state, and the magnet block 61 returns to the original position; the step that the worker moves the magnet block 61 back to the original position is reduced, and the maintenance difficulty of the worker in a narrow space is reduced; the water flow in the terminal valve flows into the first cavity 2, the second supporting block 8 floats on the water surface due to the buoyancy of the water flow to the second supporting block 8, so that the second supporting block 8 rises along with the increase of the water flow in the first cavity 2, and when the floating position of the second supporting block 8 is higher than the length of the connecting rope 82, the second connecting block pulls the through hole plug 12 out of the through hole groove 11, so that the water flow in the first cavity 2 flows out of the through hole groove 11, and the through hole plug 12 is suspended in the water flow due to the buoyancy of the water flow and the pulling force of the connecting rope 82; when a worker repairs the terminal valve, the terminal valve stops leaking water, the position of the second supporting block 8 gradually descends along with continuous discharge of water flow in the first cavity 2, the position of the through hole plug 12 also descends, when the height of the second supporting block 8 is equal to the length of the connecting rope 82, the through hole plug 12 plugs the through hole groove 11, at the moment, the worker jacks up the through hole plug 12, so that residual water in the first cavity 2 is continuously discharged, and after all water in the first cavity 2 is discharged, the worker puts down the through hole plug 12; when the water flow in the first cavity 2 increases, the second supporting block 8 can pull out the through hole plug 12 to discharge the water in the first cavity 2 in time, so that the water flow in the first cavity 2 submerges the second sensor 81 and the first sensor 71 after the terminal valve leaks for a long time, the first sensor 71 and the second sensor 81 are damaged, the normal use of the first sensor 71 and the second sensor 81 is influenced, and the use effect of the water flow-type water flow-leakage-prevention terminal valve in practical application is further ensured; the second supporting block 8 pulls out the through hole plug 12, at the moment, the through hole plug 12 floats on the water surface, water in the first cavity 2 is discharged through the through hole groove 11, water in the first cavity 2 is collected to the through hole groove 11, and meanwhile, water leaked from the terminal valve continuously flows to the first cavity 2, so that the fluctuating sliding rods 21 are positioned on two sides of the second supporting block 8 on the water surface in the first cavity 2, when the second supporting block 8 floats on the water surface, water flowing down from the valve 4 falls onto the second sensor 81, and the service life of the second sensor 81 is further ensured; when the staff repaired the terminal valve, terminal valve department stops leaking, thereby remaining water continues to discharge in cavity 2, rivers in cavity 2 when passing through-hole groove 11, the rivers velocity of flow that is close to through-hole groove 11 cell wall is relatively slow, the velocity of flow of rivers that through-hole groove 11 central point put is relatively fast, thereby form the negative pressure in the middle of rivers, and then rivers flow to the negative pressure zone on every side and form the swirl, through-hole stopper 12 is attracted by the swirl this moment, make the position of through-hole stopper 12 be perpendicular to through-hole groove 11 all the time at cavity 2 in-process that rivers were discharged, prevent the position skew of through-hole stopper 12, thereby through-hole stopper 12 stops through-hole groove 11 when the water in cavity 2 was all discharged, the manual mesh of getting rid of cavity 2 water of the staff has been reduced, the maintenance degree of difficulty of staff in narrow and small space has been reduced once more.
