Description

Technical Field

[0001] This invention relates to the field of oil and gas mixed transportation equipment, and in particular to a hydraulic high-efficiency oil and gas mixed transportation booster device. Background Technology

[0002] As oilfield development enters its mid-to-late stages, oil wells are increasingly located further away from the joint station, and the gathering and transportation radius continues to increase, leading to a sustained rise in back pressure at the distant oil wellheads, severely restricting normal oilfield production. Currently, the main methods used on-site are wellhead oil pulling or pressurization processes to alleviate the back pressure problem. The pressurization process, depending on the gas content of the produced fluid, employs either a dual-set equipment mode of "gas-liquid separation, separate pressurization, and then mixing" or a single equipment such as a screw pump for pressurization. While the former can adapt to conditions with high gas content, it involves large equipment investment and a complex process; the latter is applicable to conditions with low gas content, but as extraction conditions worsen, the content of wastewater, associated gas, carbon dioxide, sand, and other impurities in the produced fluid increases significantly, making traditional equipment such as screw pumps and centrifugal pumps prone to cavitation, wear, and blockage, resulting in decreased reliability and increased maintenance frequency.

[0003] Against this backdrop, piston pumps, due to their strong adaptability to various media and high-pressure delivery capabilities, have gradually become a focus of attention for oil and gas mixed-transport pressurization. Utility model patent CN220267922U discloses an oil and gas mixed-transport piston pump. The valve body has an outlet at the top and an inlet at the bottom, communicating with the outlet. When the lower valve core, upper valve core, and bolt move upwards, they stretch a spring, applying potential energy. Upon resetting, the spring releases this potential energy, causing the upper and lower valve cores to move closer to the valve body. The sealing gasket between the upper and lower valve cores replaces the lower valve core in contact with the outlet. The sealing gasket bends under force, sealing the gap between the outlet and the lower valve core. The contact between the lower valve core and the valve body provides a second seal. Even when the sealing gasket exceeds its usage limit, there will be no problem of incomplete sealing or liquid leakage. A limiting component restricts the position of the bolt, preventing it from loosening due to rotation caused by reciprocating motion.

[0004] The above technical solution relies on the combined action of the upper and lower valve cores and the sealing gasket between them and the liquid outlet to achieve the purpose of double sealing, in order to solve the problem of insufficient sealing caused by the sealing gasket when it exceeds the use limit. However, in actual use, there are still the following obvious defects: During long-term operation, the upper valve core is prone to jamming due to sand, scale or other impurities, or deformation due to media corrosion or fatigue, which will lead to failure to close normally. Once this problem occurs, it will cause internal backflow and a sharp drop in pump efficiency. In severe cases, it is necessary to stop the machine for disassembly and maintenance, which will affect the continuity of production and increase maintenance costs. Summary of the Invention

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides a hydraulic high-efficiency oil-gas mixed transport booster device.

[0006] The technical solution of this invention is: a hydraulic high-efficiency oil-gas mixed-transport booster device, comprising a mounting frame, on which a plurality of outer shells are mounted, each outer shell having a power chamber and a working chamber, the working chamber of the outer shell being fixedly connected and connected to symmetrically distributed outlet pipes and symmetrically distributed inlet pipes, each inlet pipe having a one-way valve, a power component being slidably connected within the outer shell, a first moving disc and a second moving disc being slidably connected to the power component, both the first and second moving discs being slidably connected to the outer shell, a valve seat being fixedly connected within the outlet pipe, a valve core being provided within the outlet pipe, the valve core being used to seal the corresponding valve seat, a first storage groove and a second storage groove being provided on the power component, a first limiting pin being slidably connected within the first storage groove of the power component, and a second limiting pin being slidably connected within the second storage groove of the power component, the first limiting pin being used to limit the first moving disc, and the second limiting pin being used to limit the second moving disc.

[0007] Furthermore, the outer casing is fixedly connected to an installation tube, which passes through the power component and is slidably connected to it in a sealed manner. A first connecting tube and a second connecting tube are fixedly connected inside the installation tube, and both the first connecting tube and the second connecting tube pass through the installation tube. The power component is provided with a first storage cavity and a second storage cavity. The first connecting tube communicates with the second storage cavity, and the second connecting tube communicates with the first storage cavity. The first storage slot of the power component communicates with the first storage cavity, and the second storage slot of the power component communicates with the second storage cavity.

[0008] Furthermore, a fixed shell is fixedly connected inside the liquid outlet pipe, and a valve stem is slidably connected to the fixed shell. The valve stem is fixedly connected to the corresponding valve core. A first spring is provided inside the fixed shell, and the first spring is fixedly connected to the corresponding valve stem. A liquid storage shell is fixedly connected to the liquid outlet pipe and is fixedly connected to and communicates with the fixed shell. The first connecting pipe and the second connecting pipe are respectively connected to the corresponding liquid storage shell through pipes. A movable plate is slidably connected inside the liquid storage shell, and a second spring is fixedly connected between the two.

[0009] Furthermore, the valve stem is provided with a blind hole, and a squeezing rod is slidably connected in the blind hole of the valve stem. The squeezing rod is slidably connected to the corresponding movable plate for limiting. A movable rod is fixedly connected to the squeezing rod. A guide groove is provided in the liquid storage shell, and the movable rod slides in the corresponding guide groove. A limit rod is fixedly connected in the guide groove, and the limit rod is used to limit the movable rod.

[0010] Furthermore, the guide groove has a cross-section of a right triangle, the limiting rod is located at the intersection of the hypotenuse and one of the right-angled sides of the right triangle, and the limiting rod is made of an elastic deformable material.

[0011] Furthermore, the extrusion rod is slidably connected to a sliding block, and a return spring is fixedly connected between the sliding block and the corresponding liquid storage shell.

[0012] Furthermore, the working cavity of the outer shell is fixedly connected to symmetrically distributed U-shaped shells, which are connected to the corresponding liquid storage shells through pipes. An installation block is slidably connected inside the U-shaped shell, and a third spring is fixedly connected to the corresponding U-shaped shell in a slidable and sealed manner. The third spring is fixedly connected to a limit block. Both the first moving disk and the second moving disk are provided with limit grooves, which are used to limit the corresponding limit blocks.

[0013] Furthermore, the limiting block is provided with an inclined surface, and the distance between the inclined surfaces of the limiting blocks symmetrically distributed within the same housing gradually increases from the side closer to the axis of the power component to the side farther away.

[0014] Furthermore, symmetrically distributed fixed rings are fixedly connected to the working cavity of the outer shell, and a movable ring is slidably connected to the fixed ring.

The rotating rod is rotatably connected to the corresponding fixed shell. The rotating rod and the corresponding threaded rod are driven by a bevel gear set.

[0016] The beneficial effects of the present invention are as follows: When the valve seat and the corresponding valve core cannot close normally, the present invention separates the moving disc from the corresponding limit pin, cuts off the connection between the power component and the moving disc, and achieves the purpose of "operating at the fault point". Thus, without stopping the operation of the entire device, the faulty valve core and valve seat can be repaired, improving the availability and continuity of the system.

[0017] When the spring force weakens, the spring force of the first spring can be adjusted by rotating the rotating rod, so that the valve seat and valve core can achieve effective sealing again, ensuring the continuous and stable operation of the device. There is no need to disassemble the device or perform complex maintenance, saving maintenance time and labor costs, while also reducing the replacement frequency of the first spring.

Detailed Implementation

[0020] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Unless otherwise specified, the symmetrical distribution settings in this article are assumed to be two for ease of understanding. Example 1

[0022] Considering that existing piston pumps require shutdown and disassembly for repair when the one-way valve at the outlet fails to close properly, affecting production continuity and increasing maintenance costs, this embodiment discloses a hydraulic high-efficiency oil-gas mixed transport booster device.

[0023] like Figures 1-8 As shown, the device includes a mounting frame 1, on which several outer shells 2 are mounted. Each outer shell 2 has a power chamber and a working chamber. The working chamber of the outer shell 2 is fixedly connected to and connected to symmetrically distributed outlet pipes 3 and symmetrically distributed inlet pipes 4. A one-way valve is installed in the inlet pipe 4. A power component 5 is slidably connected inside the outer shell 2. A first moving plate 6 and a second moving plate 7 are slidably connected to the power component 5. Both the first moving plate 6 and the second moving plate 7 are slidably connected to the outer shell 2. A valve seat 8 is fixedly connected inside the outlet pipe 3. A valve core 9 is installed inside the outlet pipe 3. The valve core 9 is used to seal the corresponding valve seat 8. The power component 5 has a first storage slot and a second storage slot. A first limiting pin 10 is slidably connected inside the first storage slot of the power component 5. A second limiting pin 11 is slidably connected inside the second storage slot of the power component 5. The first limiting pin 10 is used to limit the first moving plate 6, and the second limiting pin 11 is used to limit the second moving plate 7.

[0024] In the above scheme, the specific number of outer shells 2 is selected by the staff. The figure and text both use two as an example. The power chamber of the outer shell 2 is located at its rear and is used to drive the power component 5 to move back and forth. The power component 5 is composed of a disc part and a rod part. The figure shows the hydraulic drive method as an example. The working chamber is located at the front of the outer shell 2 and is used to temporarily store the oil-gas mixture. The liquid outlet pipe 3 is located on the upper side of the outer shell 2, and the liquid inlet pipe 4 is located on the lower side of the outer shell 2. The one-way valve in the liquid inlet pipe 4 is an existing device and is not shown in the figure. The first moving plate 6 and the second moving plate 7 both slide in the working chamber of the corresponding outer shell 2. Under normal conditions, the first moving plate 6 is in contact with the corresponding second moving plate 7. The first moving plate 6 and the corresponding second moving plate 7 divide the corresponding working chamber into front and rear parts. Under normal conditions, the first limiting pin 10 limits the corresponding first moving plate 6, and the second limiting pin 11 limits the corresponding second moving plate 7. The first limiting pin 10 and the second limiting pin 11 are both composed of a cylindrical part and a disc part, wherein the cylindrical part is located on the side of the disc part away from the central axis of the outer shell 2.

[0025] like Figures 3-8As shown, the outer casing 2 is fixedly connected to an installation tube 171, which passes through the power component 5 and is slidably connected to it in a sealed manner. A first connecting tube 18 and a second connecting tube 19 are fixedly connected inside the installation tube 171. Both the first connecting tube 18 and the second connecting tube 19 pass through the installation tube 171. The power component 5 is provided with a first storage cavity 20 and a second storage cavity 21. The first connecting tube 18 communicates with the second storage cavity 21, and the second connecting tube 19 communicates with the first storage cavity 20. The first storage slot of the power component 5 communicates with the first storage cavity 20, and the second storage slot of the power component 5 communicates with the second storage cavity 21.

[0026] In the above scheme, the mounting pipe 171 is located in the middle of the outer shell 2 and the mounting pipe 171 penetrates the outer shell 2; taking the movement process of the first limiting pin 10 as an example: when the hydraulic oil flows through the second connecting pipe 19 into the first storage groove on the corresponding power component 5, the hydraulic oil flows into the corresponding first storage cavity 20, causing the corresponding first limiting pin 10 to be squeezed and move towards the side closer to the central axis of the outer shell 2.

[0027] like Figures 4-7 , Figure 9 and Figure 10 As shown, a fixed housing 12 is fixedly connected inside the outlet pipe 3. A valve stem 13 is slidably connected to the fixed housing 12, and the valve stem 13 is fixedly connected to the corresponding valve core 9. A first spring 14 is provided inside the fixed housing 12, and the first spring 14 is fixedly connected to the corresponding valve stem 13. A liquid storage shell 15 is fixedly connected to and communicates with the fixed housing 12. A first connecting pipe 18 and a second connecting pipe 19 are respectively connected to the corresponding liquid storage shell 15 through pipes. A movable plate 16 is slidably connected inside the liquid storage shell 15. A second spring 161 is fixedly connected between the two. A blind hole is provided in the valve stem 13. A squeezing rod 17 is slidably connected in the blind hole of the valve stem 13. The squeezing rod 17 is slidably connected to the corresponding moving plate 16. A moving rod 170 is fixedly connected to the squeezing rod 17. A guide groove 1701 is provided in the liquid storage shell 15. The moving rod 170 slides in the corresponding guide groove 1701. A limiting rod 1702 is fixedly connected in the guide groove 1701. The limiting rod 1702 is used to limit the moving rod 170.

[0028] In the above scheme, the valve core 9 is located below the corresponding fixed shell 12, and the valve stem 13 is located at the lower part of the corresponding fixed shell 12. In this embodiment, the first spring 14 is fixedly connected to the corresponding fixed shell 12; the moving plate 16 and the corresponding liquid storage shell 15 together form a cavity, and the cavity stores hydraulic oil; the rear liquid storage shell 15 is connected to the first connecting pipe 18, and the front liquid storage shell 15 is connected to the second connecting pipe 19; the squeeze rod 17 can only slide up and down along the corresponding moving plate 16, and the valve stem 13 drives the moving rod 170 to move along the corresponding guide groove 1701.

[0029] like Figure 10As shown, the cross-section of the guide groove 1701 is a right triangle, and the limiting rod 1702 is located at the intersection of the hypotenuse and one of the right-angled sides of the right triangle. The limiting rod 1702 is made of an elastic and deformable material.

[0030] In the above scheme, the shape of the guide groove 1701 is defined. The guide groove 1701 is composed of a vertical part, a horizontal part and an inclined part, and the angle between the right-angled triangle horizontal part and the inclined part is greater than 45°, which is used to reduce the resistance of the moving rod 170 during the movement. When the pressing rod 17 is not moved, the moving rod 170 is located at the junction of the horizontal part and the inclined part of the corresponding guide groove 1701. The limiting rod 1702 is deformed by the pressing of the moving rod 170. The lower side of the limiting rod 1702 is fixedly connected to the corresponding fixed shell 12, and the fixed position is located at the junction of the vertical part and the inclined part of the corresponding guide groove 1701.

[0031] like Figure 10 As shown, the extrusion rod 17 is slidably connected to a sliding block 1703, and a reset spring 1704 is fixedly connected between the sliding block 1703 and the corresponding liquid storage shell 15.

[0032] In the above scheme, the reset spring 1704 is always in a stored state, which is used to drive the compression rod 17 to reset downward.

[0033] like Figures 4-7 , Figure 9 and Figure 11 As shown, the working cavity of the outer shell 2 is fixedly connected with symmetrically distributed U-shaped shells 22. The U-shaped shells 22 are connected to the corresponding liquid storage shells 15 through pipes. The U-shaped shells 22 are sealed and slidably connected with mounting blocks 23. The mounting blocks 23 are fixedly connected with third springs 24. The third springs 24 are fixedly connected with limiting blocks 25 that are sealed and slidably connected with the corresponding U-shaped shells 22. The first moving disk 6 and the second moving disk 7 are both provided with limiting grooves 26. The limiting grooves 26 are used to limit the corresponding limiting blocks 25.

[0034] In the above scheme, the two U-shaped shells 22 on the same outer shell 2 are symmetrically distributed front and back, and the U-shaped shell 22 is composed of two vertical tubes of different lengths and a horizontal tube. The mounting block 23 is located in the shorter vertical tube on the U-shaped shell 22. Hydraulic oil is stored in the U-shaped shell 22. The front limiting block 25 is used to limit the second moving disk 7, and the rear limiting block 25 is used to limit the first moving disk 6.

[0035] like Figure 11 As shown, the limiting block 25 is provided with an inclined surface. The distance between the inclined surfaces of the limiting blocks 25 symmetrically distributed in the same housing 2 gradually increases from the side closer to the axis of the power component 5 to the side farther away.

[0036] In the above scheme, the inclined surface on the limiting block 25 is located on its upper side. When the limiting block 25 moves to the limit position relative to the U-shaped shell 22, the lower side of its upper inclined surface is not higher than the lower side of the limiting groove 26, so that the first moving disk 6 and the second moving disk 7 can smoothly squeeze the corresponding limiting block 25 during the movement, so that the limiting block 25 can smoothly enter the corresponding limiting groove 26.

[0037] like Figure 4 , Figure 6 and Figure 7 As shown, symmetrically distributed fixed rings 29 are fixedly connected inside the working cavity of the outer shell 2. The fixed rings 29 are slidably connected to the movable rings 30. A fourth spring 31 is fixedly connected between the movable rings 30 and the corresponding fixed rings 29. The working cavity of the outer shell 2 is provided with symmetrically distributed air holes 32. The movable rings 30 are used to block the corresponding air holes 32. The first movable disk 6 and the second movable disk 7 are both provided with connecting holes 33. The air holes 32 supply air to the working cavity of the outer shell 2 through the connecting holes 33.

[0038] In the above scheme, the two fixed rings 29, the two movable rings 30, the two fourth springs 31, the two air holes 32 and the two connecting holes 33 are all distributed symmetrically in front and behind. When the first movable disk 6 and the second movable disk 7 respectively contact the corresponding fixed rings 29, the connecting holes 33 on them respectively connect with the corresponding air holes 32.

[0039] The specific workflow of the above scheme is as follows: When this device is needed to transport an oil-gas mixture, the operator connects all the outlet pipes 3 and all the inlet pipes 4 to the corresponding pipelines in sequence. Then, the existing hydraulic conveying device is used to supply hydraulic oil to the rear side of the power chambers of the two outer shells 2, so that the two power components 5 move forward synchronously (initially, the power components 5 are located at the rear). The following description takes the process of one of the power components 5 moving forward as an example: During the forward movement of the power component 5, the power component 5 drives the first moving disk 6 and the second moving disk 7 to move forward synchronously through the first limiting pin 10 and the second limiting pin 11 respectively, so that the pressure in the working chamber on the outer shell 2 located behind the second moving disk 7 is reduced and a negative pressure is formed, thereby opening the one-way valve in the rear liquid inlet pipe 4, so that the oil-gas mixture enters the rear part of the working chamber on the outer shell 2 through the rear liquid inlet pipe 4.

[0040] When the first moving disk 6 moves forward to the position where it contacts the front moving ring 30, the first moving disk 6 drives the moving ring 30 to move forward synchronously and compresses the front fourth spring 31. During this process, the contact position between the moving ring 30 and the front air hole 32 changes continuously, and the first moving disk 6 gradually blocks the air hole 32 until the first moving disk 6 moves forward to the limit position. At this time, the connecting hole 33 on the first moving disk 6 connects with the front air hole 32. At this time, external air can flow into the connecting hole 33 on the first moving disk 6 through the front air hole 32, and the power component 5 stops moving forward.

[0041] After the power component 5 stops moving forward, the one-way valve in the rear inlet pipe 4 gradually closes. When the one-way valve in the rear inlet pipe 4 is completely closed, the operator controls the power component 5 to move backward through the existing hydraulic oil delivery device, and drives the first moving plate 6 and the second moving plate 7 to move backward synchronously. The second moving plate 7 pushes the oil-gas mixture in the working chamber of the outer shell 2 (the part of the working chamber on the outer shell 2 behind the second moving plate 7), so that the oil-gas mixture flows upward along the rear outlet pipe 3 (during this process, the one-way valve in the front inlet pipe 4 opens at the same time, and the oil-gas mixture enters the front part of the first moving plate 6), and pushes the rear valve core 9 during the flow, so that the valve core 9 drives the valve stem 13 to move upward synchronously, and compresses and stores the first spring 14 on the rear side.

[0042] During the upward movement of the rear valve stem 13, the return spring 1704 is stretched and stored, and the extrusion rod 17 driven by the valve stem 13 moves. The extrusion rod 17 drives the moving rod 170 to move along the inclined part on the guide groove 1701, so that the moving rod 170 gradually moves away from the valve stem 13 and extrudes the corresponding moving plate 16 (causing the second spring 161 to compress and store energy), thereby causing the moving plate 16 to move away from the valve stem 13. At the same time, during the movement of the moving plate 16, a portion of the hydraulic oil in the reservoir 15 is forced into the first connecting pipe 18 and flows along the first connecting pipe 18 into the second storage cavity 21, and finally flows into the second storage tank of the power component 5. The hydraulic oil flowing into the second storage tank extrudes the second limiting pin 11 inside, causing the second limiting pin 11 to move towards the central axis of the outer shell 2, thereby causing the second limiting pin 11 to gradually lose contact with the second moving disc 7.

[0043] Another portion of the hydraulic oil in the reservoir 15 flows into the U-shaped shell 22 on the rear side, causing the mounting block 23 to be squeezed and drive the corresponding limiting block 25 to move upward synchronously through the corresponding third spring 24, so that the upper side of the limiting block 25 gradually protrudes out of the U-shaped shell 22.

[0044] As the moving rod 170 moves upward along the inclined portion of the corresponding guide groove 1701, when the moving rod 170 contacts the corresponding limiting rod 1702, the limiting rod 1702 undergoes elastic deformation due to the compression of the moving rod 170 as the moving rod 170 continues to move. This continues until the moving rod 170 reaches its limit position (i.e., when it reaches the junction of the inclined and vertical portions of the guide groove 1701, the valve stem 13 moves upward to its limit position simultaneously, and the pressing rod 17 moves out of the blind hole of the valve stem 13). At this point, the moving rod 170 loses contact with the corresponding limiting rod 1702, and the limiting rod 1702 resets under its own elastic force. Simultaneously, the pressing rod 17 drives the corresponding sliding block 1703 to reset downward under the action of the corresponding reset tension spring 1704 (during this process, the pressing rod 17 contacts the outer wall of the valve stem 13 and is limited by the valve stem 13 and cannot reset).

[0045] When the extrusion rod 17 is located in the vertical part of the corresponding guide groove 1701, the moving plate 16 moves to the limit position, and at the same time, the mounting block 23 and the second limit pin 11 both move to the limit position. The second limit pin 11 loses contact with the second moving disk 7. At this time, the first moving disk 6 continues to move backward under the action of the power component 5, thereby pushing the second moving disk 7 to continue to move backward.

[0046] When the second moving disc 7 moves backward to contact the rear limiting block 25, the lower side of its upper limit groove 26 presses against the inclined surface of the rear limiting block 25, causing the limiting block 25 to move downward relative to the corresponding mounting block 23, and compressing the third spring 24 between them, until the second moving disc 7 moves backward to its limit position, at which point the limiting block 25 is completely aligned with the limiting groove 26, so that the limiting block 25 enters the limiting groove 26 under the action of the third spring 24, limiting the second moving disc 7. Then, the operator controls the power component 5 to stop moving through the existing hydraulic oil delivery device.

[0047] During the process of the first moving disk 6 being driven backward by the aforementioned power component 5, the first moving disk 6 gradually loses contact with the front moving ring 30, thereby reducing the force on the front fourth spring 31. This causes the front moving ring 30 to move backward synchronously under the action of the front fourth spring 31 and re-seal the front air hole 32. During the process of the second moving disk 7 moving backward, the second moving disk 7 gradually contacts the rear moving ring 30 and pushes the rear moving ring 30 to move backward, so that the connecting hole 33 on the second moving disk 7 connects with the rear air hole 32 (refer to the process of the connecting hole 33 on the first moving disk 6 connecting with the front air hole 32).

[0048] After the power component 5 stops moving backward, the rear valve core 9 gradually moves downward under the action of the first spring 14. If the rear valve core 9 can be successfully reset to the initial position, the blind hole on the valve stem 13 will be re-aligned with the extrusion rod 17. Then, the second spring 161 drives the moving plate 16 and the extrusion rod 17 to move synchronously towards the valve stem 13, so that the extrusion rod 17 is inserted into the blind hole of the valve stem 13. At the same time, the moving rod 170 moves along the horizontal part of the guide groove 1701. During the movement of the moving plate 16, the hydraulic oil in the first connecting pipe 18 and the second storage cavity 21 is drawn back, so that the rear mounting block 23 and the second limit pin 11 are reset. After the two are reset, the operator controls the power component 5 to drive the first moving plate 6 and the second moving plate 7 to move forward through the existing hydraulic oil delivery device. During the process of squeezing the oil-gas mixture in front of the first moving plate 6 from the front liquid outlet pipe 3, the oil-gas mixture also enters the rear part of the second moving plate 7 through the rear liquid inlet pipe 4 to transport the oil-gas mixture.

[0049] If the valve core 9 on the rear side cannot return to its initial position due to the accumulation of impurities or deformation of the two, the squeeze rod 17 and the blind hole on the valve stem 13 on the rear side cannot be aligned. Therefore, the moving plate 16 on the rear side cannot return to its initial position, thus preventing the second moving disc 7 from connecting to the power component 5 through the second limit pin 11. During the forward movement of the power component 5, the first moving disc 6 is moved forward only through the first limit pin 10 (during this process, external air enters between the first moving disc 6 and the second moving disc 7 through the air hole 32 on the rear side and the connection hole 33 on the second moving disc 7). Subsequently, the operator can clean and maintain the valve seat 8 and the valve core 9 on the rear side without stopping the machine, in preparation for subsequent use. Example 2

[0050] Based on Example 1, such as Figure 7 and Figure 9 As shown, it also includes mounting parts 34 in the same number as the fixed housing 12. The mounting parts 34 are fixedly connected to the corresponding fixed housing 12. The mounting parts 34 are rotatably connected to threaded rods 35. The threaded rods 35 are threadedly connected to push plates 36. The push plates 36 are slidably connected to the corresponding fixed housing 12. The push plates 36 are fixedly connected to the corresponding first spring 14. The liquid outlet pipe 3 is rotatably connected to a rotating rod 37. The rotating rod 37 is rotatably connected to the corresponding fixed housing 12, and the rotating rod 37 and the corresponding threaded rod 35 are driven by a bevel gear set.

[0051] In the above scheme, the mounting part 34 is located above the corresponding valve core 9, and the first spring 14 is always in a stored state. Under normal conditions, the push plate 36 is located at the uppermost side of the corresponding threaded rod 35. The push plate 36 can only slide up and down within the corresponding fixed shell 12. During the normal use of this device, if the corresponding valve seat 8 and the corresponding valve core 9 cannot be completely sealed due to the weakening of the elasticity of one of the first springs 14, the following is an example of the rear valve seat 8 and valve core 9 not being completely sealed: the operator rotates the rear rotating rod 37, which drives the threaded rod 35 to rotate through the bevel gear set, thereby causing the push plate 36 to move downward along the fixed shell 12 and squeeze the first spring 14, thereby increasing the elasticity of the first spring 14, that is, increasing the downward squeezing force of the valve rod 13, improving the sealing performance of the valve seat 8 and the valve core 9, so that the two can maintain an effective working state and reduce the overall replacement frequency.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
