A linear horizontal suction and discharge valve structure Technical Field
[0001] This invention relates to the field of suction and discharge valve technology, and in particular to a linear horizontal suction and discharge valve structure. Background Technology
[0002] Currently, most common suction and discharge valves have a vertical structure. For example, in a plunger pump, the suction and discharge valves are arranged vertically in the hollow cavity of the pump head. In the prior art, patent document CN104747430B discloses a hydraulic end for an emulsion pump, including: a valve body, on which a plunger cavity and a suction and discharge valve cavity are provided, the plunger cavity and the suction and discharge valve cavity are connected; a cylinder liner, located in the suction and discharge valve cavity, the cylinder liner is provided with a suction and discharge valve assembly; a stuffing box assembly, located in the plunger cavity of the valve body, the stuffing box assembly includes a stuffing box body; a plunger, one end of the plunger is located in the stuffing box body, the other end of the plunger is connected to the drive shaft of the emulsion pump, the drive shaft rotates to drive the plunger to reciprocate within the stuffing box body.
[0003] With the continuous increase in mining height of fully mechanized coal mining faces, higher requirements are placed on the pump head structure and suction / discharge valve layout of the supporting high-pressure, high-flow emulsion pump station. Vertical suction / discharge valves have many drawbacks:
[0004] 1. Poor liquid suction stability; when the liquid suction pressure is low, it is difficult to push the suction valve core to open the valve port, resulting in unstable liquid supply.
[0005] 2. The sealing surface is subjected to high vertical pressure and impact, which can easily cause wear and leakage, affecting the reliability and safety of the equipment.
[0006] 3. When the liquid flows vertically, the plunger consumes a lot of energy to overcome the weight of the liquid, resulting in low energy utilization efficiency. Summary of the Invention
[0007] The purpose of this invention is to address the shortcomings of existing technologies, such as poor liquid absorption stability, easy leakage, and high energy consumption, by proposing a linear horizontal suction and discharge valve structure.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a linear horizontal suction and discharge valve structure, including a valve body, with a cylinder sleeve and an end cover fixedly installed at both ends of the valve body, a positioning sleeve, a suction valve sleeve, a valve seat, and a discharge valve sleeve installed inside the valve body, a plunger slidably installed inside the cylinder sleeve, and an output port provided on the end face of the end cover.
[0009] A suction valve core is slidably installed inside the suction valve sleeve. A suction valve spring is provided inside the suction valve sleeve to press against the suction valve core. The inner hole of the suction valve sleeve is a plunger cavity, and the end of the plunger can extend into the plunger cavity.
[0010] The valve seat surface has a through-hole for liquid inlet and a through-hole for liquid outlet.
[0011] A drain valve core is slidably installed in the inner cavity of the drain valve sleeve, and a drain valve spring is provided in the inner cavity of the drain valve sleeve to press against the drain valve core. The inner cavity of the drain valve sleeve is connected to the output port. A connecting channel is opened on the end face of the drain valve sleeve away from the end cover. The outlet end of the connecting channel is aligned with the inlet hole. The inlet end of the connecting channel extends to the outer circular surface of the drain valve sleeve. A liquid storage tank is fixedly installed on the lower surface of the valve body. The inner cavity of the liquid storage tank is connected to the inlet of the connecting channel.
[0012] Under the action of the suction valve spring, the suction valve core is tightly attached to the end face of the valve seat and covers the inlet hole. Under the action of the discharge valve spring, the discharge valve core covers the outlet hole. When the plunger reciprocates, it discharges the emulsion from the outlet in a horizontal direction. In this process, the plunger overcomes the gravity of the liquid with low energy consumption, effectively avoids vertical hydraulic fluctuations, and ensures that the emulsion pump using the suction and discharge valve structure of this invention supplies stable and accurate flow rate, ensuring a continuous and stable power supply to the actuator.
[0013] Preferably, the liquid suction valve core has an annular structure, and multiple connecting rods are fixedly installed on the end face of the liquid suction valve core. Each connecting rod slides through the liquid suction valve sleeve, and a magnetic post is fixedly installed at the end of each connecting rod. A first mounting sleeve is embedded in the end face of the positioning sleeve, and a spiral coil is embedded in the first mounting sleeve. The magnetic post is movably inserted into the first mounting sleeve.
[0014] Preferably, a second mounting sleeve is fixedly installed inside the cylinder liner, and an induction coil is provided inside the second mounting sleeve. The plunger slides through the second mounting sleeve, and multiple magnetic rings are embedded on the surface of the plunger. The spiral coil and the induction coil are electrically connected through a switch controller. When the switch controller is closed, the circuit of the spiral coil and the induction coil is in a closed state. When the switch controller is open, the circuit of the spiral coil and the induction coil is in a closed state.
[0015] Preferably, when the switch controller is closed, during the process of the plunger moving away from the suction valve sleeve, the induced current generated by the induction coil is introduced into the spiral coil, causing the spiral coil to generate a gradually decreasing magnetic field that attracts the magnetic column, providing a force to the suction valve core in the opposite direction to the pressure on the valve seat. During the process of the plunger moving closer to the suction valve sleeve, the induced current generated by the induction coil is introduced into the spiral coil, causing the spiral coil to generate a magnetic field that repels the magnetic column, providing a force to the suction valve core that pressures the valve seat. Due to the gradually decreasing magnetic attraction of the spiral coil to the magnetic column, the impact force of the suction valve core on the valve seat is reduced, which is beneficial to protecting the sealing surface between the suction valve core and the valve seat.
[0016] Preferably, when the switch controller is turned on, the suction valve core moves left and right, causing the magnetic column to slide back and forth in the first mounting sleeve. The induction coil generates an induced current. By detecting the change in the induced current, the sealing condition and fault point of the suction and discharge valve structure can be determined, making it easier to replace parts, greatly reducing maintenance difficulty, time consumption and cost, and ensuring that the pump station can quickly resume operation.
[0017] Preferably, the positioning sleeve, suction valve sleeve, valve seat, and discharge valve sleeve are arranged horizontally in a straight line and are slidably installed into the valve body in sequence. The positioning sleeve, suction valve sleeve, valve seat, and discharge valve sleeve are clamped and fixed between the cylinder liner and the end cover. After removing the end cover, it is convenient to replace its internal components, thus achieving the effect of easy maintenance.
[0018] Preferably, the connecting channel includes a plurality of connecting holes and an annular groove. The plurality of connecting holes are arranged in a circumferential array. The annular groove is formed on the outer circular surface of the drain valve sleeve. Each connecting hole is connected to the annular groove. The valve body is provided with a suction hole and a return channel. The annular groove is connected to the inner cavity of the storage tank through the suction hole. One end of the return channel is connected to the suction hole, and the other end of the return channel is connected to the inner cavity of the cylinder sleeve. A one-way valve is provided in the return channel, and the liquid leaking from the cylinder sleeve can flow to the storage tank through the return channel.
[0019] The present invention has the following beneficial effects:
[0020] 1. This invention proposes a suction and discharge valve structure for use in emulsion pumps. By setting up a horizontally arranged positioning sleeve, suction valve sleeve, valve seat, and discharge valve sleeve, the emulsion is discharged horizontally from the output port when the plunger reciprocates. In this process, the plunger overcomes the gravity of the liquid with low energy consumption, effectively avoids vertical hydraulic fluctuations, and ensures stable and accurate flow when the emulsion pump using the suction and discharge valve structure of this invention supplies liquid. This ensures a continuous and stable power supply to the actuator, meeting the needs of operating scenarios such as high-extraction hydraulic supports.
[0021] 2. This invention proposes a suction and discharge valve structure. By setting up a magnetic column and a spiral coil, when the suction valve core moves left and right, it drives the magnetic column to move back and forth. The spiral coil cuts the magnetic field of the magnetic column to generate an induced current. Since the movement speed and amplitude of the suction valve core are affected by the sealing condition between the suction valve core and the valve seat, and between the discharge valve core and the valve seat, when the sealing condition is poor, leakage occurs, which causes changes in the movement speed and amplitude of the suction valve core. This indirectly causes abnormalities in the induced current of the spiral coil. By detecting changes in the induced current, the sealing condition and fault point of the suction and discharge valve structure can be determined, making the replacement of parts more convenient, greatly reducing the difficulty, time and cost of maintenance, and ensuring that the pump station can quickly resume operation.
[0022] 3. The present invention proposes a suction and discharge valve structure. By setting an induction coil and a magnetic ring, when the plunger reciprocates and extends, the induction coil generates an induced current and introduces the induced current into the spiral coil, providing the magnetic column with alternating magnetic attraction and repulsion forces, thereby driving the suction valve core to move left and right. When suctioning, the resistance of the suction valve core movement is reduced. When discharging, the suction valve core is pressed tightly, reducing the leakage between the suction valve core and the valve seat.
[0023] In addition, as the plunger moves away from the suction valve sleeve and comes to rest, the induced current generated by the induction coil gradually decreases, the magnetic attraction of the spiral coil to the magnetic column gradually decreases, and the suction valve spring pushes the suction valve core to move towards the valve seat. Due to the gradually decreasing magnetic attraction of the spiral coil to the magnetic column, the impact force of the suction valve core on the valve seat is reduced, which helps to protect the sealing surface between the suction valve core and the valve seat, reduce wear, and prolong the sealing performance.
[0024] 4. The present invention proposes a suction and discharge valve structure in which the positioning sleeve, suction valve sleeve, valve seat, and discharge valve sleeve are slidably installed into the valve body in sequence, and the positioning sleeve, suction valve sleeve, valve seat, and discharge valve sleeve are clamped and fixed between the cylinder liner and the end cover. After the end cover is removed, it is convenient to replace its internal components, achieving the effect of easy maintenance. With reliable structural design and excellent performance, it reduces downtime failures and effectively improves production efficiency. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0034] Referring to Figures 1-6, a linear horizontal suction and discharge valve structure includes a valve body 1. A cylinder sleeve 2 and an end cover 3 are respectively fixedly installed at both ends of the valve body 1 by bolts. A positioning sleeve 4, a suction valve sleeve 5, a valve seat 6, and a discharge valve sleeve 7 are installed inside the valve body 1. A plunger 8 is slidably installed inside the cylinder sleeve 2. An output port 9 is provided on the end face of the end cover 3.
[0035] Specifically, the positioning sleeve 4, suction valve sleeve 5, valve seat 6, and discharge valve sleeve 7 are arranged horizontally in a straight line and are slidably installed into the valve body 1 in sequence. The positioning sleeve 4, suction valve sleeve 5, valve seat 6, and discharge valve sleeve 7 are clamped and fixed between the cylinder liner 2 and the end cover 3.
[0036] A suction valve core 10 is slidably installed inside the suction valve sleeve 5. A suction valve spring 11 is provided inside the suction valve sleeve 5 to press against the suction valve core 10. The inner hole of the suction valve sleeve 5 is a plunger cavity, and the end of the plunger 8 can extend into the plunger cavity.
[0037] The surface of the valve seat 6 is provided with a liquid inlet hole 12 and a liquid outlet hole 13 that pass through from left to right.
[0038] The inner cavity of the drain valve sleeve 7 is slidably fitted with a drain valve core 14, and the inner cavity of the drain valve sleeve 7 is provided with a drain valve spring 15 that abuts against the drain valve core 14. The inner cavity of the drain valve sleeve 7 is connected to the output port 9. A connecting channel is opened on the end face of the drain valve sleeve 7 away from the end cover 3. The outlet end of the connecting channel is aligned with the inlet hole 12. The inlet end of the connecting channel extends to the outer circular surface of the drain valve sleeve 7. A liquid storage tank 16 is fixedly installed on the lower surface of the valve body 1. The inner cavity of the liquid storage tank 16 is connected to the inlet of the connecting channel.
[0039] The aforementioned connecting channel includes several connecting holes 23 and an annular groove 24. The several connecting holes 23 are arranged in a circumferential array, and the annular groove 24 is formed on the outer circular surface of the drain valve sleeve 7. Each connecting hole 23 is connected to the annular groove 24.
[0040] The valve body 1 has a suction hole 25 and a return channel 26 inside. The annular groove 24 is connected to the inner cavity of the storage tank 16 through the suction hole 25. One end of the return channel 26 is connected to the suction hole 25, and the other end of the return channel 26 is connected to the inner cavity of the cylinder liner 2. A one-way valve is installed in the return channel 26. The liquid leaking from the cylinder liner 2 can flow into the storage tank 16 through the return channel 26. It should be noted that the liquid level at the highest point in the storage tank 16 is higher than that of the drain valve sleeve 7 to ensure that the liquid can be sucked into the connecting channel.
[0041] Under the action of the suction valve spring 11, the suction valve core 10 is in close contact with the end face of the valve seat 6 and covers the inlet hole 12. Under the action of the drain valve spring 15, the drain valve core 14 covers the outlet hole 13.
[0042] This horizontal suction and discharge valve structure is used in emulsion pumps. It mainly achieves the functions of suction and discharge by controlling the horizontal flow of liquid. The working principle is as follows:
[0043] Referring to Figure 5, when the plunger 8 moves to the left, the pressure inside the plunger cavity in the suction valve sleeve 5 decreases accordingly, forming a pressure difference with the suction hole 25. Driven by this pressure difference, the suction valve core 10 overcomes the elastic force of the suction valve spring 11 and generates displacement, opening the inlet hole 12. At this time, the liquid enters the plunger cavity from the suction hole 25 through the gap between the suction valve core 10 and the valve seat 6.
[0044] After the liquid suction process is completed, the plunger 8 begins to move to the right, and the pressure in the plunger cavity of the suction valve sleeve 5 gradually increases. On the one hand, the suction valve core 10 quickly closes the suction hole 25 under the combined action of the increased pressure and the elastic force of the suction valve spring 11, preventing liquid backflow. At the same time, as the pressure in the plunger cavity increases, when it exceeds the sum of the pressure of the discharge valve spring 15 and the liquid pressure on the discharge valve core 14, the discharge valve core 14 is pushed open, and the liquid is discharged horizontally to the output port 9 through the outlet hole 13.
[0045] After the drainage process ends, the plunger 8 moves to the left again, and the pressure in the plunger chamber decreases once more. This creates a pressure difference between the two ends of the drainage valve core 14. At the same time, under the action of the drainage valve spring 15, the drainage valve core 14 closes quickly. Meanwhile, due to the decrease in the pressure in the plunger chamber, the suction valve core 10 opens again, and a new round of suction and drainage process begins. This cycle repeats continuously, forming a complete suction and drainage cycle.
[0046] This invention proposes a suction and discharge valve structure. By setting up a horizontally arranged positioning sleeve 4, suction valve sleeve 5, valve seat 6, and discharge valve sleeve 7, the plunger 8 reciprocates and extends, discharging the emulsion horizontally from the output port 9. In this process, the plunger 8 overcomes the gravity of the liquid with low energy consumption and effectively avoids vertical hydraulic fluctuations. This ensures that the emulsion pump using the suction and discharge valve structure of this invention provides stable and accurate flow rate, ensuring a continuous and stable power supply to the actuator and meeting the needs of operating scenarios such as high-extraction hydraulic supports.
[0047] This invention proposes a suction and discharge valve structure in which the positioning sleeve 4, suction valve sleeve 5, valve seat 6, and discharge valve sleeve 7 are sequentially slidably installed into the valve body 1. The positioning sleeve 4, suction valve sleeve 5, valve seat 6, and discharge valve sleeve 7 are clamped and fixed between the cylinder sleeve 2 and the end cover 3. After removing the end cover 3, it is convenient to replace its internal components, achieving the effect of easy maintenance. With its reliable structural design and excellent performance, it reduces downtime failures and effectively improves production efficiency.
[0048] In this embodiment, referring to Figure 2, the liquid suction valve core 10 has an annular structure. Multiple connecting rods 17 are fixedly installed on the end face of the liquid suction valve core 10. Each connecting rod 17 slides through the liquid suction valve sleeve 5, and a magnetic post 18 is fixedly installed at the end of each connecting rod 17. A first mounting sleeve 19 is embedded in the end face of the positioning sleeve 4. A spiral coil 20 is embedded in the first mounting sleeve 19. The magnetic post 18 is movably inserted into the first mounting sleeve 19, as shown in Figure 3.
[0049] In this embodiment, referring to Figure 4, a second mounting sleeve 27 is fixedly installed inside the cylinder liner 2. An induction coil 21 is provided inside the second mounting sleeve 27. The plunger 8 slides through the second mounting sleeve 27. A plurality of magnetic rings 22 are embedded on the surface of the plunger 8.
[0050] The spiral coil 20 and the induction coil 21 are electrically connected through a switch controller. When the switch controller is closed, the circuit of the spiral coil 20 and the induction coil 21 is in a closed state. When the switch controller is open, the circuit of the spiral coil 20 and the induction coil 21 is in a closed state.
[0051] Specifically, when the switch controller is turned on, the liquid suction valve core 10 moves left and right, causing the magnetic column 18 to slide back and forth in the first mounting sleeve 19, and the induction coil 21 generates an induced current, which is used as a detection signal.
[0052] When the switch controller is closed, as the plunger 8 moves away from the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, causing the spiral coil 20 to generate a gradually decreasing magnetic field that attracts the magnetic column 18. This provides the suction valve core 10 with a force opposite to that of the valve seat 6, as shown by F_magnetic in Figure 6. The force of the suction valve spring 11 pressing the valve seat 6 is F_spring. As the plunger 8 moves closer to the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, causing the spiral coil 20 to generate a magnetic field that repels the magnetic column 18. This provides the suction valve core 10 with a force that presses the valve seat 6, which is consistent with the direction of F_spring in Figure 6. It should be noted that the change in the direction of the force exerted by the spiral coil 20 on the magnetic column 18 is determined by the winding direction of the induction coil 21 and the moving direction of the magnetic ring 22. This is common knowledge in electrical engineering and will not be elaborated here.
[0053] This invention proposes a suction and discharge valve structure. By setting up a magnetic column 18 and a spiral coil 20, when the suction valve core 10 moves left and right, it drives the magnetic column 18 to move back and forth. The spiral coil 20 cuts the magnetic field of the magnetic column 18 to generate an induced current. Since the movement speed and amplitude of the suction valve core 10 are affected by the sealing condition between the suction valve core 10 and the valve seat 6, and between the discharge valve core 14 and the valve seat 6, when the sealing condition is poor, leakage occurs, which causes the movement speed and amplitude of the suction valve core 10 to change, indirectly causing an abnormality in the induced current of the spiral coil 20. This induced current is used as a detection signal. By detecting the change in the induced current, the sealing condition and fault point of the suction and discharge valve structure can be determined, making the replacement of parts more convenient, greatly reducing the difficulty, time and cost of maintenance, and ensuring that the pump station can quickly resume operation. It should be noted that there are multiple valve core structures in one suction and discharge valve structure, and multiple plungers 8 act simultaneously. By comparing the abnormality of the induced current, the fault point can be determined.
[0054] This invention proposes a suction and discharge valve structure. By setting an induction coil 21 and a magnetic ring 22, when the plunger 8 reciprocates and extends, the induction coil 21 generates an induced current and introduces the induced current into the spiral coil 20, providing alternating magnetic attraction and repulsion forces to the magnetic column 18, thereby driving the suction valve core 10 to move left and right. When suctioning, the resistance of the suction valve core 10 is reduced. When discharging, the suction valve core 10 is pressed tightly, reducing the leakage between the suction valve core 10 and the valve seat 6.
[0055] Furthermore, as the plunger 8 moves away from the suction valve sleeve 5 and comes to rest at the leftmost end, the induced current generated by the induction coil 21 gradually decreases, and the magnetic attraction force of the spiral coil 20 on the magnetic column 18 gradually decreases. The suction valve spring 11 pushes the suction valve core 10 to move towards the valve seat 6. Due to the gradually decreasing magnetic attraction force of the spiral coil 20 on the magnetic column 18, the impact force of the suction valve core 10 on the valve seat 6 is reduced, which helps to protect the sealing surface between the suction valve core 10 and the valve seat 6, reduce wear, and prolong the sealing performance. Moreover, as the plunger 8 moves closer to the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, causing the spiral coil 20 to generate a magnetic field that repels the magnetic column 18, providing a force for the suction valve core 10 to press against the valve seat 6. When the speed of the reciprocating extension and retraction of the plunger 8 changes, the magnetic attraction and repulsion forces acting on the magnetic column 18 also change accordingly, meeting the usage requirements of coordinated action of the suction valve core 10 and greatly improving the reliability and safety of the equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
