TECHNICAL FIELD

[0001] The utility model belongs to pipe force valve technical field, specifically relates to a kind of intelligent regulation and control type's pipe force valve. BACKGROUND

[0002] Pipe force valve is a new type of pump station control equipment, is widely used in automatic water supply and drainage pump station, electric power, metallurgy, petrochemical, municipal, environmental protection and other industries.Its main functions include cut-off, check and eliminate water hammer hazard, protect the safety of water pump and pipe network system.But, the existing pipe force valve is usually set a pressure relief port to the impact force of water hammer buffering, the position of pressure relief under this kind of mode is relatively single, and the buffering effect is general.

[0003] The patent with the announcement number CN212775898U relates to a pipe force valve with a slow-closing piston, which is provided with a valve body, a valve rod, a valve plate, a valve seat, a flow-through hole, a hinge mechanism, a rotating rod, a control system, a pull rod, a slow-closing plate, a main shaft and the like.When the valve is closed, the valve plate is closed with the valve seat, and the valve plate hinders the flow of most of the medium.At this time, part of the medium still flows out of the flow-through hole, thereby playing a role of medium buffering and reducing the damage caused by water hammer effect.Subsequently, the slow-closing plate is driven to rotate around the main shaft by the pull rod and the hinge mechanism, thereby plugging the flow-through hole on the valve plate, and further completely hindering the flow of the medium.

[0004] However, the above-mentioned scheme can only buffer the impact force caused by water hammer effect through a single flow-through hole, and the acting position under this kind of mode is relatively single, so that the flow pressure in the flow-through hole is relatively large, and the overall buffering effect of water hammer effect is poor, which cannot disperse the pressure better, so that the equipment is prone to damage under the impact of large water hammer, and has certain limitations in actual use.

[0023] The outer surface of the valve stem 4 is rotationally provided with a positioning ring 5, the inner surface of the positioning ring 5 is fixedly provided with a first matching block 26 and a second matching block 27, the outer surface of the valve stem 4 is fixedly provided with a fixed block 21, the fixed block 21 is in abutting transmission cooperation with the second matching block 27, and the side of the second matching block 27 facing the fixed block 21 is provided with a buffer pad (not shown in the figure). The outer surface of the positioning ring 5 is fixedly provided with a connecting crank 15, the connecting crank 15 is provided with an arc-shaped sliding groove 20 and a small valve plate 16, and the small valve plate 16 is in transmission cooperation with the connecting crank 15 to block the pressure relief hole 24.

[0024] The valve body 1 is provided with a diaphragm seat 8, the diaphragm seat 8 is provided with a diaphragm chamber, the diaphragm chamber is provided with a diaphragm 11 and a top rod 9 in sliding manner, the top rod 9 is connected with the diaphragm 11 through a diaphragm pressing plate 10, the top rod 9 is in transmission cooperation with the connecting crank 15, the bottom of the top rod 9 is fixedly provided with a rotating shaft 25, and the rotating shaft 25 is limitingly and slidingly arranged in the sliding groove 20.

[0025] The diaphragm 11 divides the diaphragm chamber into two upper and lower chambers in sealed manner. The valve body 1 is provided with an inlet bypass pipeline assembly 12 and an outlet bypass pipeline assembly 13, the inlet bypass pipeline assembly 12 is in communication with the lower chamber, and the outlet bypass pipeline assembly 13 is in communication with the upper chamber. The inlet bypass pipeline assembly 12 and the outlet bypass pipeline assembly 13 are both provided with a pilot operated electromagnetic valve (not shown in the figure), a pipeline, a filter (not shown in the figure) and the like, the valve body 1 is fixedly provided with a pressure transmitter 22, a control assembly 6 and a photovoltaic power generation plate 14, the photovoltaic power generation plate 14 is in communication with the control assembly 6 through a wire tube 7, the photovoltaic power generation plate 14 provides a power source for the control assembly 6, and the pressure transmitter 22 is electrically connected with the control assembly 6.

[0026] The above-mentioned structures all belong to the prior art, and the present scheme will not be described in detail.

[0027] In addition, when the large valve plate 2 and the pressure relief hole 24 are in a sealed state, the positional relationship of the fixed block 21, the first matching block 26 and the second matching block 27 is as shown in Figure 4 When the second matching block 27 limits the large valve plate 2, the positional relationship of the fixed block 21, the first matching block 26 and the second matching block 27 is as shown in Figure 5 At this time, a gap is left between the large valve plate 2 and the valve seat 17.

[0028] Working principle: after the valve body 1 is connected to the pipeline, the water pump is started, as shown in Figure 2 The water flows from the right side, the pressure transmitter 22 senses that the pressure on the right side increases, the pilot operated electromagnetic valve in the inlet bypass pipeline assembly 12 is opened, and part of the water flow flows into the lower chamber of the diaphragm chamber through the inlet bypass pipeline assembly 12.

[0029] The liquid flowing into the lower chamber pushes the diaphragm 11 upward, which in turn moves the push rod 9 upward. The push rod 9 then moves the rotating shaft 25 upward, causing the connecting crank 15 to rotate around the central axis of the valve stem 4. This causes the small valve plate 16 to disengage from the pressure relief hole 24, thus slowly opening the small valve plate 16 and opening the pressure relief hole 24. Simultaneously, under the force of the water, the large valve plate 2 and the valve stem 4 rotate around the central axis of the valve stem 4, causing the large valve plate 2 and the small valve plate 16 to open synchronously, thereby completing the valve opening.

[0030] During this process, the rotating shaft 25 slides relative to the sliding groove 20, and the return water in the upper chamber of the diaphragm 11 flows out through the outlet bypass pipe assembly 13. The rotation of the connecting crank 15 will drive the positioning ring 5 to rotate synchronously, so that the first mating block 26 and the second mating block 27 rotate synchronously.

[0031] When the water pump stops, the flow velocity on the right side of the pipe decreases rapidly and approaches zero. The large valve plate 2 loses the thrust of the water flow and falls rapidly under its own gravity, cutting off the water flow. During the fall of the large valve plate 2, it will drive the valve stem 4 to rotate in the opposite direction, causing the fixed block 21 to rotate in the opposite direction around the central axis of the valve stem 4.

[0032] However, during this process, the pilot-operated solenoid valves in the inlet bypass pipeline assembly 12 and the outlet bypass pipeline assembly 13 are not opened, and because the diaphragm chamber is in a sealed state, the diaphragm 11 will not move downwards. Therefore, the push rod 9, the connecting crank 15, and the positioning ring 5 will not move. When the fixed block 21 rotates to abut against the second mating block 27, the fixed block 21 stops rotating. Figure 5 As shown. At this time, there is a certain gap between the large valve plate 2 and the valve seat 17. The water will flow out from the pressure relief hole 24 and the gap between the large valve plate 2 and the bottom of the valve seat 17, thereby increasing the pressure relief position of the water flow, thus optimizing the buffering effect and reducing the impact of water hammer on the equipment.

[0033] When the pressure transmitter 22 senses a decrease in impact force, it transmits a signal to the control component 6, causing the pilot-operated solenoid valve in the outlet bypass pipeline assembly 13 to open. This causes the diaphragm 11 to move downward, which in turn drives the rotating shaft 25 downward via the push rod 9. This causes the connecting crank 15 to rotate in the opposite direction around the central axis of the valve stem 4. The connecting crank 15 drives the first mating block 26 and the second mating block 27 to rotate synchronously via the positioning ring 5. At this time, the second mating block 27 no longer limits the fixed block 21, and the large valve plate 2 resets and seals the valve seat 17. As the positioning ring 5 continues to rotate in the opposite direction, the small valve plate 16 gradually seals the pressure relief hole 24, thus completing the valve closure.

[0034] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
