Description

Technical Field

[0001] The invention relates to the technical field of liquid suction and discharge valves, and in particular to a linear horizontal suction and discharge valve structure. Background Art

[0002] At present, most common suction and discharge valves are vertical structures. For example, the suction and discharge valves in the plunger pump are vertically arranged in the hollow chamber of the pump head body. In the prior art, the patent document with the announcement number CN104747430B discloses a hydraulic end for an emulsion pump, comprising: a valve body, a plunger cavity and a suction and discharge valve cavity are provided on the valve body, and the plunger cavity is connected with the suction and discharge valve cavity; a cylinder sleeve, located in the suction and discharge valve cavity, and a suction and discharge valve assembly is provided in the cylinder sleeve; a stuffing box assembly, located in the plunger cavity of the valve body, and the stuffing box assembly includes a stuffing box body; a plunger, one end of the plunger is located in the stuffing box body, and the other end of the plunger is connected to the transmission shaft of the emulsion pump, and the rotation of the transmission shaft drives the plunger to reciprocate in the stuffing box body.

[0003] With the continuous increase in the mining height of coal enterprises' fully mechanized mining faces, higher requirements have been placed on the pump head structure and suction and discharge valve layout of the supporting fully mechanized high-pressure and high-flow emulsion pump station. The vertical suction and discharge valve has many disadvantages: 1. The liquid suction stability is poor. When the liquid suction pressure is low, it is difficult to push the suction valve core to open the valve port, and the liquid supply is unstable.

[0004] 2. The sealing surface is subject to large vertical pressure and impact force, which is easy to wear and cause leakage, affecting the reliability and safety of the equipment.

[0005] 3. When the liquid flows vertically, the plunger consumes a lot of energy to overcome the gravity of the liquid, and the energy utilization efficiency is low. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of poor liquid absorption stability, easy leakage and high energy consumption in the prior art, and to propose a linear horizontal suction and discharge valve structure.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a linear horizontal suction and discharge valve structure, comprising a valve body, a cylinder sleeve and an end cover are respectively fixedly installed at both ends of the valve body, a positioning sleeve, a suction valve sleeve, a valve seat, and a discharge valve sleeve are installed in the valve body, a plunger is slidably installed in the cylinder sleeve, and an output port is arranged on the end surface of the end cover; A liquid suction valve core is slidably installed in the liquid suction valve sleeve, a liquid suction valve spring is arranged in the liquid suction valve sleeve to press against the liquid suction valve core, the inner hole of the liquid suction valve sleeve is a plunger cavity, and the end of the plunger can extend into the plunger cavity; The surface of the valve seat is provided with a liquid inlet hole and a liquid outlet hole penetrating from left to right; A drain valve core is slidably mounted 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 communicated with the output port, a communication channel is provided on the end surface of the drain valve sleeve away from the end cover, the outlet end of the communication channel is aligned with the liquid inlet hole, the inlet end of the communication channel extends to the outer circumferential surface of the drain valve sleeve, a liquid storage tank is fixedly mounted on the lower surface of the valve body, and the inner cavity of the liquid storage tank is communicated with the inlet of the communication channel; Under the action of the suction valve spring, the suction valve core is close to the end face of the valve seat and covers the liquid inlet hole. Under the action of the discharge valve spring, the discharge valve core covers the liquid outlet hole. When the plunger reciprocates and extends, the emulsion is discharged from the output port in the horizontal direction. In this process, the plunger consumes little energy to overcome the gravity of the liquid, effectively avoiding vertical hydraulic fluctuations, ensuring that the emulsion pump using the suction and discharge valve structure of the present invention supplies liquid with a stable and accurate flow rate, thereby ensuring continuous and stable energy supply to the actuator.

[0008] Preferably, the liquid suction valve core is an annular structure, and a plurality of connecting rods are fixedly installed on the end surface of the liquid suction valve core, each connecting rod slides through the liquid suction valve sleeve, and a magnetic column is fixedly installed on the end of each connecting rod, and a first mounting sleeve is embedded in the end surface of the positioning sleeve, a spiral coil is embedded in the first mounting sleeve, and the magnetic column is movably inserted in the first mounting sleeve.

[0009] Preferably, a second mounting sleeve is fixedly installed in the cylinder sleeve, an induction coil is arranged in the second mounting sleeve, the plunger slides through the second mounting sleeve, a plurality of magnetic rings are embedded in 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 connected state, and when the switch controller is opened, the circuit of the spiral coil and the induction coil is in a disconnected state.

[0010] Preferably, when the switch controller is closed, in 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, so that the spiral coil generates a gradually decreasing magnetic field that attracts the magnetic column, and provides the suction valve core with a force in the opposite direction of pressing the valve seat; in 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, so that the spiral coil generates a magnetic field that repels the magnetic column, and provides the suction valve core with a force that presses the valve seat; due to the gradually decreasing magnetic attraction of the spiral coil on 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.

[0011] 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, and 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 judged, making replacement of parts more convenient, greatly reducing the difficulty, time and cost of maintenance, and ensuring that the pump station can be quickly restored to operation.

[0012] Preferably, the positioning sleeve, suction valve sleeve, valve seat and discharge valve sleeve are arranged horizontally in a line and are slidably installed in 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 sleeve and the end cover. After removing the end cover, it is convenient to replace its internal components, thereby achieving an effect of easy maintenance.

[0013] Preferably, the connecting channel comprises a plurality of connecting holes and annular grooves, the plurality of connecting holes are arranged in a circular array, the annular groove is formed on the outer circumferential surface of the drain valve sleeve, each connecting hole is connected with the annular groove, a suction hole and a reflux channel are respectively provided inside the valve body, the annular groove is connected with the inner cavity of the liquid storage tank through the suction hole, one end of the reflux channel is connected with the suction hole, and the other end of the reflux channel is connected with the inner cavity of the cylinder sleeve, and a one-way valve is arranged in the reflux channel, so that the leaked liquid in the cylinder sleeve can flow into the liquid storage tank through the reflux channel.

[0014] The present invention has the following beneficial effects: 1. The present invention proposes a suction and discharge valve structure, which is applied to an emulsion pump. By setting a positioning sleeve, a suction valve sleeve, a valve seat, and a discharge valve sleeve arranged horizontally in a line, the emulsion is discharged from the output port in a horizontal direction when the plunger reciprocates and extends. In this process, the plunger consumes little energy to overcome the gravity of the liquid, effectively avoiding vertical hydraulic fluctuations, ensuring that the emulsion pump using the suction and discharge valve structure of the present invention has a stable and accurate flow rate when supplying liquid, ensuring continuous and stable energy supply to the actuator, and meeting the needs of operating scenarios such as large mining height hydraulic supports.

[0015] 2. The present invention proposes a suction and discharge valve structure. By setting 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. The movement speed and amplitude of the suction valve core are affected by the sealing conditions 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, there is leakage, which causes the movement speed and amplitude of the suction valve core to change, indirectly causing the induced current of the spiral coil to become abnormal. The sealing condition and fault point of the suction and discharge valve structure can be judged by detecting the change of the induced current, making it more convenient to replace parts, greatly reducing the difficulty, time and cost of maintenance, and ensuring that the pump station can be quickly restored to operation.

[0016] 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 retracts to do work, 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 magnetic repulsion forces, thereby driving the suction valve core to move left and right. When suctioning liquid, the resistance of the suction valve core to the movement is reduced. When discharging liquid, the suction valve core is pressed tightly to reduce the leakage between the suction valve core and the valve seat; In addition, in the process of the plunger moving away from the suction valve sleeve and coming to a standstill, the induced current generated by the induction coil gradually decreases, the magnetic attraction of the spiral coil on the magnetic column gradually decreases, and the suction valve spring pushes the suction valve core to move toward the valve seat. Due to the gradually decreasing magnetic attraction of the spiral coil on 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, reducing wear and extending the sealing performance.

[0017] 4. The present invention proposes a suction and discharge valve structure, in which a positioning sleeve, a suction valve sleeve, a valve seat, and a discharge valve sleeve are slidably installed in the valve body in sequence, and the positioning sleeve, the suction valve sleeve, the valve seat, and the discharge valve sleeve are clamped and fixed between the cylinder sleeve and the end cover. After removing the end cover, it is convenient to replace its internal components, thereby achieving an easy maintenance effect. Relying on reliable structural design and excellent performance, it reduces downtime failures and greatly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Reference Figure 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 in the valve body 1, a plunger 8 is slidably installed in the cylinder sleeve 2, and an output port 9 is arranged on the end surface of the end cover 3.

[0023] Specifically, the positioning sleeve 4, the suction valve sleeve 5, the valve seat 6, and the discharge valve sleeve 7 are arranged horizontally in a line and are slidably installed in the valve body 1 in sequence, and the positioning sleeve 4, the suction valve sleeve 5, the valve seat 6, and the discharge valve sleeve 7 are clamped and fixed between the cylinder sleeve 2 and the end cover 3.

[0024] A suction valve core 10 is slidably installed in the suction valve sleeve 5. A suction valve spring 11 is arranged in 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.

[0025] The surface of the valve seat 6 is provided with a liquid inlet hole 12 and a liquid outlet hole 13 penetrating from left to right.

[0026] A drain valve core 14 is slidably mounted in the inner cavity of the drain valve sleeve 7, and a drain valve spring 15 is provided in the inner cavity of the drain valve sleeve 7 to press against the drain valve core 14. The inner cavity of the drain valve sleeve 7 is communicated with the output port 9. A communication channel is provided on the end surface of the drain valve sleeve 7 away from the end cover 3. The outlet end of the communication channel is aligned with the liquid inlet hole 12. The inlet end of the communication channel extends to the outer circumferential surface of the drain valve sleeve 7. A liquid storage tank 16 is fixedly mounted on the lower surface of the valve body 1. The inner cavity of the liquid storage tank 16 is communicated with the inlet of the communication channel. The communication passage includes a plurality of communication holes 23 and annular grooves 24 . The plurality of communication holes 23 are arranged in a circular array. The annular grooves 24 are formed on the outer circumferential surface of the drain valve sleeve 7 . Each communication hole 23 is connected to the annular grooves 24 .

[0027] A suction hole 25 and a reflux channel 26 are respectively provided inside the valve body 1. The annular groove 24 is connected with the inner cavity of the liquid storage tank 16 through the suction hole 25. One end of the reflux channel 26 is connected with the suction hole 25, and the other end of the reflux channel 26 is connected with the inner cavity of the cylinder sleeve 2. A one-way valve is provided in the reflux channel 26. The leaked liquid in the cylinder sleeve 2 can flow into the liquid storage tank 16 through the reflux channel 26. It should be noted that the liquid level at the highest point of the liquid in the liquid storage tank 16 is higher than the drain valve sleeve 7, so as to ensure that the liquid can be sucked into the connecting channel.

[0028] Under the action of the suction valve spring 11 , the suction valve core 10 is tightly attached to the end surface of the valve seat 6 and covers the liquid inlet hole 12 . Under the action of the discharge valve spring 15 , the discharge valve core 14 covers the liquid outlet hole 13 .

[0029] The horizontal suction and discharge valve structure is used in emulsion pumps. It mainly realizes the suction and discharge functions by controlling the flow of liquid in the horizontal direction. The following is the detailed working principle: refer to Figure 5 When the plunger 8 moves to the left, the internal pressure of the plunger cavity in the suction valve sleeve 5 decreases, and a pressure difference is formed between the suction hole 25. Driven by the pressure difference, the suction valve core 10 overcomes the elastic force of the suction valve spring 11 and produces displacement, opening the liquid 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.

[0030] After the suction process is completed, the plunger 8 starts to move to the right, and the pressure in the plunger cavity in 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 effect of the increased pressure and the elastic force of the suction valve spring 11 to prevent the liquid from flowing back; at the same time, as the plunger cavity pressure increases and 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.

[0031] At the end of the discharge process, the plunger 8 moves to the left again, and the pressure in the plunger chamber decreases again, which causes a pressure difference to form at both ends of the discharge valve core 14. At the same time, under the action of the discharge valve spring 15, the discharge valve core 14 is quickly closed. At the same time, due to the decrease in the pressure in the plunger chamber, the suction valve core 10 is opened again, and a new round of suction and discharge process is started. This cycle is repeated to form a complete suction and discharge cycle.

[0032] The present invention proposes a suction and discharge valve structure, which arranges a positioning sleeve 4, a suction valve sleeve 5, a valve seat 6, and a discharge valve sleeve 7 in a horizontal line. When the plunger 8 reciprocates and extends, the emulsion is discharged from the output port 9 in the horizontal direction. In this process, the plunger 8 consumes little energy to overcome the gravity of the liquid, effectively avoiding vertical hydraulic fluctuations, ensuring that the emulsion pump using the suction and discharge valve structure of the present invention has a stable and accurate flow rate when supplying liquid, ensuring continuous and stable energy supply to the actuator, and meeting the needs of operating scenarios such as large mining height hydraulic supports.

[0033] The present invention proposes a suction and discharge valve structure, in which a positioning sleeve 4, a suction valve sleeve 5, a valve seat 6, and a discharge valve sleeve 7 are slidably installed in the valve body 1 in sequence, and the positioning sleeve 4, the suction valve sleeve 5, the valve seat 6, and the 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, thereby achieving an effect of easy maintenance. Relying on reliable structural design and excellent performance, it reduces downtime failures and greatly improves production efficiency.

[0034] In this embodiment, reference Figure 2 The liquid suction valve core 10 is annular in structure, and a plurality of connecting rods 17 are fixedly installed on the end surface of the liquid suction valve core 10. Each connecting rod 17 slides through the liquid suction valve sleeve 5, and a magnetic column 18 is fixedly installed on the end of each connecting rod 17. A first mounting sleeve 19 is embedded on the end surface of the positioning sleeve 4, and a spiral coil 20 is embedded in the first mounting sleeve 19. The magnetic column 18 is movably inserted in the first mounting sleeve 19. For details, see Figure 3 .

[0035] In this embodiment, reference Figure 4 A second mounting sleeve 27 is fixedly installed in the cylinder sleeve 2, an induction coil 21 is arranged in the second mounting sleeve 27, the plunger 8 slides through the second mounting sleeve 27, and a plurality of magnetic rings 22 are embedded on the surface of the plunger 8.

[0036] 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 connected state. When the switch controller is opened, the circuit of the spiral coil 20 and the induction coil 21 is in a disconnected state.

[0037] 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.

[0038] When the switch controller is closed, in the process of the plunger 8 moving away from the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, so that the spiral coil 20 generates a gradually decreasing magnetic field that attracts the magnetic column 18, providing the suction valve core 10 with a force in the opposite direction to the pressing valve seat 6, such as Figure 6As shown in the figure, the force of the suction valve spring 11 pressing the valve seat 6 is F spring. When the plunger 8 moves close to the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, so that the spiral coil 20 generates a magnetic field that repels the magnetic column 18, providing a force for the suction valve core 10 to press the valve seat 6, and Figure 6 The direction of the F-spring is consistent. 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.

[0039] The present invention proposes a suction and discharge valve structure. By setting 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, and 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 conditions 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, there is leakage, which causes the movement speed and amplitude of the suction valve core 10 to change, indirectly causing the induced current of the spiral coil 20 to be abnormal. The induced current is used as a detection signal. By detecting the change of the induced current, the sealing condition and fault point of the suction and discharge valve structure can be judged, making it more convenient to replace parts, greatly reducing the difficulty, time and cost of maintenance, and ensuring that the pump station can be quickly restored to operation. It should be noted that there are multiple sets of valve core structures in a suction and discharge valve structure, and multiple plungers 8 act simultaneously. By comparing the abnormality of the above-mentioned induced current, the fault point can be judged.

[0040] The present invention proposes a suction and discharge valve structure, by providing an induction coil 21 and a magnetic ring 22, when the plunger 8 reciprocates and retracts to do work, the induction coil 21 generates an induced current, and introduces the induced current into the spiral coil 20, providing the magnetic column 18 with alternating magnetic attraction and magnetic repulsion forces, thereby driving the suction valve core 10 to move left and right, reducing the resistance of the suction valve core 10 when suctioning liquid, and compressing the suction valve core 10 when discharging liquid, reducing the leakage between the suction valve core 10 and the valve seat 6; In addition, in the process of the plunger 8 moving away from the suction valve sleeve 5 to the leftmost end and coming to rest, 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, and the suction valve spring 11 pushes the suction valve core 10 to move toward 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 is beneficial to protecting the sealing surface between the suction valve core 10 and the valve seat 6, reducing wear and extending the sealing performance. Moreover, in the process of the plunger 8 moving close to the suction valve sleeve 5, the induced current generated by the induction coil 21 is introduced into the spiral coil 20, so that the spiral coil 20 generates a magnetic field that repels the magnetic column 18, providing the suction valve core 10 with a force to press the valve seat 6. When the speed of the reciprocating telescopic action of the plunger 8 changes, the magnetic attraction and magnetic repulsion forces acting on the magnetic column 18 also change accordingly, meeting the use requirements of the coordinated action of the suction valve core 10 and greatly improving the reliability and safety of the equipment.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
