Description

Technical Field

[0001] The present invention relates to the technical field of valve groups, and particularly to a regulating valve for a multi-parameter intelligent mixing valve group skid. Background Art

[0002] A valve group skid is a prefabricated modular system integrating multiple valves, multiple pipelines, various instruments, a control terminal, and other related devices. The control terminal is used to regulate the electric valves in different pipelines so that the flowing media in multiple pipelines flow into related devices for processing at different flow rates. The above-mentioned various instruments are used to respectively display parameters such as the flow rate, pressure, and temperature of the flowing media.

[0003] When using a valve group skid in the petroleum field, some pipelines in the valve group skid are required to transport petroleum-based media. However, due to the characteristics of petroleum-based media such as high temperature and corrosion, after the regulating valve in this pipeline is opened, the sealing ring on the blocking valve block in the valve will directly contact the petroleum-based media. At this time, the corrosiveness of the petroleum-based media is likely to cause the sealing ring to age, resulting in poor sealing effect of the valve, causing the valve group skid to leak the transported medium and affecting the service life of the valve group skid.

Detailed implementation mode

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments 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 some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0019] When the valve in the valve bank skid is in the open state, the sealing ring in the valve will directly contact the conveying medium. At the same time, the flowing conveying medium scours the sealing ring, which easily accelerates the aging of the sealing ring, resulting in poor sealing effect during the subsequent use of the valve, causing the conveying medium to leak and affecting the normal use of the valve bank skid.

[0020] Embodiment 1: A regulating valve for a multi-parameter intelligent mixing valve bank skid, referring to Figures 1-4 As shown, it includes: a support 1; a control cabinet 101 and a process equipment 102, both installed on the support 1; a plurality of conveying components 103, all installed on the support 1, and a variety of instruments are installed on the conveying components 103; a plurality of valve bodies 2, respectively installed in adjacent conveying components 103, a valve cover 201 is installed on the valve body 2, a valve stem 202 is slidably arranged on the valve cover 201, a valve block 203 is installed on the valve stem 202, the valve block 203 is in sealing cooperation with the adjacent valve body 2, the valve block 203 is provided with a conical surface for adjusting the size of the flowing cross-section in the adjacent valve body 2, and a sealing ring 2031 is installed on the valve block 203; a plurality of first sliding sleeves 204, respectively slidably arranged on the adjacent valve blocks 203 and slidably connected to the adjacent valve stems 202, and a tension spring is installed between the valve block 203 and the adjacent first sliding sleeve 204, and the first sliding sleeve 204 is used to block the adjacent sealing ring 2031 to isolate the sealing ring 2031 from the flowing medium; a plurality of actuator units 3, respectively installed on the adjacent valve covers 201, and the actuator unit 3 is used to control the movement of the adjacent valve stem 202.

[0021] In the above solution, the first sliding sleeve 204 is made of heat-insulating material. When the first sliding sleeve 204 isolates the flowing medium from the sealing ring 2031, it weakens the temperature transfer of the flowing medium to the sealing ring 2031, thereby slowing down the aging of the sealing ring 2031. When the valve body 2 is in the blocked state, the tension spring between the first sliding sleeve 204 and the adjacent valve block 203 is in a stretched state. In the attached drawing, the process equipment 102 is a tank body, and the conveying component 103 is equipped with instruments such as a temperature transmitter and a pressure transmitter. The control cabinet 101 is electrically connected to all the electrical components in this article.

[0022] The skid-mounted unit has the following characteristics: Modular design: The valve skid is a pre-designed and manufactured module that can be assembled and tested in the factory and then transported to the site for installation; High integration: It includes multiple valves, pipelines, instruments, control systems, etc., forming a complete functional unit; Flexibility: It can be customized according to specific requirements and is suitable for different process flows and application scenarios; Easy installation: Since it is a prefabricated module, the on-site installation workload is small, which can shorten the project cycle.

[0023] The execution unit 3 is divided into: pneumatic actuator, electric actuator, hydraulic actuator, electro-pneumatic conversion actuator, intelligent actuator according to different power sources and working principles; The above different power sources have different characteristics, which are understandable to those skilled in the art and will not be elaborated one by one here. In the attached drawing, it is a schematic diagram of a pneumatic actuator, and this structure is only a simple schematic diagram in the existing structure diagram.

[0024] Refer to Figure 3 and Figure 4 As shown, it also includes: a gasket 4, which is installed between the adjacent valve body 2 and the adjacent valve cover 201. The gasket 4 is provided with two stepped surfaces, and the two stepped surfaces of the gasket 4 are respectively in contact and cooperation with the adjacent valve body 2 and the adjacent valve cover 201, so as to improve the sealing performance between the adjacent valve body 2 and the adjacent valve cover 201.

[0025] In the above solution, a concave pit is provided on the lower side surface of the gasket 4, which is used to guide the flowing medium to squeeze the concave pit surface of the gasket 4, so that the gasket 4 closely adheres to the adjacent valve body 2, improving the sealing performance of the device and preventing the conveyed medium from leaking.

[0026] Refer to Figure 3 and Figure 4As shown in the figure, it further includes: a valve seat 5, detachably installed in the adjacent valve body 2. The valve seat 5 is in contact and cooperation with the adjacent valve block 203. The valve seat 5 is provided with an annular groove, and the annular groove of the valve seat 5 is in extrusion cooperation with the adjacent sealing ring 2031. On one side of the valve seat 5 close to the adjacent first sliding sleeve 204, there are circumferentially uniformly distributed grooves. The valve seat 5 is provided with a conical surface, and the first sliding sleeve 204 is provided with a conical surface. The conical surface of the valve seat 5 is in extrusion cooperation with the conical surface of the adjacent first sliding sleeve 204.

[0027] In the above solution, the valve seat 5 is in threaded cooperation with the adjacent valve body 2. A rubber ring is provided on the lower side of the valve seat 5 to improve the sealing performance between the valve seat 5 and the adjacent valve body 2. At the same time, the detachable installation of the valve seat 5 facilitates the operator to quickly replace the valve seat 5, which is convenient for maintenance and replacement, improves the reliability of the device. At the same time, only the maintenance method of replacing the worn valve seat 5 greatly reduces the maintenance cost. The above method of regular maintenance and replacement of key detachable parts extends the service life of the entire system. When the channel in the valve body 2 is in a blocked state, the first sliding sleeve 204, the adjacent valve seat 5 and the adjacent valve block 203 are in contact and cooperation to form a folded surface. This design utilizes complex geometric shapes to increase the path length and resistance of fluid leakage, thereby reducing the possibility of leakage, that is, improving the sealing performance of the device.

[0028] Refer to Figures 4-6 As shown in the figure, it further includes: a first sliding frame 6, slidably arranged in the adjacent valve block 203. A tension spring is installed between the first sliding sleeve 204 and the adjacent first sliding frame 6. The first sliding frame 6 is in extrusion cooperation with the adjacent sealing ring 2031. The middle of the sealing ring 2031 is provided with an annular chamber storing gas. On both sides of the sealing ring 2031, there are limiting rings with a triangular cross-section. The valve block 203 is provided with two annular grooves, and the two annular grooves of the valve block 203 are respectively in limiting cooperation with the adjacent limiting rings on the adjacent sealing ring 2031.

[0029] In the above solution, the number of tension springs between the first sliding sleeve 204 and the adjacent first sliding frame 6 is four (the number of four is for illustration in the drawings, and this number can be set according to specific requirements). When the channel in the valve body 2 is in a blocked state, the tension spring between the first sliding frame 6 and the adjacent first sliding sleeve 204 is in a stretched state. The tension of this spring acts on the adjacent sealing ring 2031 through the first sliding frame 6, and the sealing ring 2031 is deformed by extrusion and closely adheres to the adjacent valve block 203 and the adjacent valve seat 5, further improving the sealing performance of the mating surface at the blocked part.

[0030] Refer to Figure 5 and Figure 6 As shown in the figure, it further includes: a sliding plug 7, slidably arranged in the valve block 203. A spring is installed between the valve block 203 and the adjacent sliding plug 7. The first sliding frame 6 is provided with a blind hole, and the blind hole of the first sliding frame 6 is in limiting cooperation with the adjacent sliding plug 7.

[0031] In the above solution, the number of sliding plugs 7 is four (the number of four is for illustration in the attached drawing, and the specific number can be set accordingly according to specific requirements). When the channels in the valve body 2 are in a blocked state, the tension spring between the first sliding frame 6 and the adjacent first sliding sleeve 204 is in a stretched state, and at the same time, the spring connected to the sliding plug 7 is in a compressed state. When all the sliding plugs 7 are located in the adjacent blind holes on the adjacent first sliding frames 6, under the action of the elastic force of the springs connected to all the sliding plugs 7, the limiting force of all the sliding plugs 7 on the adjacent first sliding frame 6 is less than the pulling force of the tension spring between the first sliding frame 6 and the first sliding sleeve 204 in the completely blocked state of the valve body 2. When the valve block 203 moves downward to cooperate with the adjacent valve seat 5 for blocking operation, as the valve block 203 is gradually inserted into the adjacent valve seat 5, the valve seat 5 restricts the movement of the adjacent first sliding sleeve 204, making the distance between the first sliding frame 6 and the adjacent first sliding sleeve 204 increase. That is, at this time, the tension spring between the first sliding frame 6 and the adjacent first sliding sleeve 204 is gradually stretched. However, at this time, due to the limitation of the sliding plug 7 on the first sliding frame 6, the first sliding frame 6 does not move immediately, that is, the extrusion of the first sliding frame 6 on the adjacent sealing ring 2031 is delayed, thereby weakening the extrusion force between the sealing ring 2031 and the adjacent first sliding sleeve 204, and thus reducing the wear degree of the sealing ring 2031 during the movement between the adjacent first sliding sleeves 204, that is, extending the service life of the sealing ring 2031.

[0032] Specific working process: After this device is placed at the designated position by a hoisting device, the operator connects and installs this device with the corresponding pipelines or equipment. Subsequently, the operator controls the valves and instruments in this device to work through the control cabinet 101. Taking one of the conveying components 103 as an example, the control cabinet 101 controls the execution unit 3 to work. The execution unit 3 controls the valve rod 202 to move. The valve rod 202 drives the valve block 203 and its connected components to move together. The valve block 203 gradually moves away from contact with the valve seat 5, so that the flowing medium in the valve body 2 flows through the gap between the valve block 203 and the valve seat 5. By controlling the moving distance of the valve block 203, the gap between the valve block 203 and the valve seat 5 is controlled, so as to realize the regulation of the flow rate of the flowing medium in the conveying component 103.

[0033] After the flowing medium passes through the gap between the valve block 203 and the valve seat 5, the flowing medium flows into the process equipment 102, and the subsequent flowing medium undergoes corresponding processing processes or the flowing medium is conveyed to other processing processes, completing the function of this valve bank skid.

[0034] During the upward movement of the valve block 203, under the tensile force of the tension spring connected to the first sliding sleeve 204, the first sliding sleeve 204 remains in contact with the valve seat 5. During this process, the valve block 203 and the sealing ring 2031 gradually move into the first sliding sleeve 204. After the sealing ring 2031 enters the first sliding sleeve 204, the valve block 203 continues to move upward and drives the first sliding sleeve 204 to move upward together through the tension spring. The movement of the valve block 203 regulates the flow rate of the flowing medium in the valve body 2.

[0035] During the process of the valve block 203 retracting into the first sliding sleeve 204, the tension spring between the first sliding frame 6 and the first sliding sleeve 204 gradually contracts and returns to its original state, that is, the first sliding frame 6 gradually weakens the extrusion force on the sealing ring 2031, and the first sliding frame 6 gradually moves downward relative to the valve block 203. After the sealing ring 2031 retracts into the first sliding sleeve 204, the valve block 203 continues to retract into the first sliding sleeve 204, causing the first sliding frame 6 to continue to move relative to the valve block 203 until the blind hole on the first sliding frame 6 is directly opposite to the sliding plug 7. The sliding plug 7 is affected by the elastic force of the connected spring, and the sliding plug 7 will be inserted into the blind hole of the first sliding frame 6. At this time, the sliding plug 7 limits the first sliding frame 6, completing the opening state of the valve body 2.

[0036] During the above working process, the sealing ring 2031 retracts into the first sliding sleeve 204, isolating the sealing ring 2031 from contact with the flowing medium, preventing the flowing medium from corroding the sealing ring 2031, thereby further extending the service life of the sealing ring 2031, that is, preventing the flowing medium from leaking in the skid-mounted unit and improving the service life of the device.

[0037] When it is necessary to block the valve body 2, the corresponding components are controlled by the control cabinet 101 to perform the above reverse operation. During the process of the valve block 203 being inserted into the valve seat 5, the valve block 203 gradually moves downward, but the valve seat 5 restricts the movement of the first sliding sleeve 204, causing the valve block 203 to move downward relative to the first sliding sleeve 204 and stretch the connected tension spring. During the stretching process of the tension spring between the first sliding sleeve 204 and the first sliding frame 6, due to the limiting effect of the sliding plug 7 on the first sliding frame 6, the extrusion of the first sliding frame 6 on the sealing ring 2031 is delayed, thereby avoiding excessive extrusion force between the sealing ring 2031 and the first sliding sleeve 204, reducing the wear of the sealing ring 2031 during its movement in the first sliding sleeve 204, that is, extending the service life of the sealing ring 2031. When the sealing ring 2031 is directly opposite to the annular groove on the valve seat 5, the valve block 203 stops moving, and at this time, the tensile force of the tension spring between the first sliding sleeve 204 and the first sliding frame 6 is greater than the limiting force of the sliding plug 7 on the first sliding frame 6. The first sliding frame 6 squeezes the sealing ring 2031, causing the sealing ring 2031 to closely adhere to the annular groove on the valve seat 5, completing the blocking operation of the valve body 2. After that, when it is necessary to open the valve body 2, repeat the above operation.

[0038] Embodiment 2: On the basis of Embodiment 1, with reference to Figure 3 and Figure 7 as shown, it further includes: a plurality of fixed shells 8, installed in adjacent valve covers 201 and in contact and cooperation with adjacent gaskets 4, the valve stem 202 penetrates through the adjacent fixed shell 8 and is slidably connected thereto, an elastic sleeve 801 is fixedly connected inside the fixed shell 8, the inner diameter of the elastic sleeve 801 gradually decreases in the direction of the adjacent gasket 4 from the valve cover 201, the elastic sleeve 801 is in contact and cooperation with the adjacent valve stem 202, the actuator unit 3 is installed with a conduit 301, and the actuator unit 3 controls the movement of the adjacent valve stem 202 by using gas; a plurality of trigger assemblies are respectively arranged on adjacent conduits 301, and the trigger assemblies are used to control the deformation of the corresponding elastic sleeve 801 and control the elastic sleeve 801 to disengage from the contact with the adjacent valve stem 202.

[0039] In the above solution, the number of elastic sleeves 801 is three evenly distributed (this number is a schematic in the drawing, and this number can be set according to specific needs), and at this time the actuator unit 3 is a pneumatic actuator. The actuator unit 3 is composed of an intelligent control unit, two shells, a diaphragm, a conduit, and a spring. The valve stem 202 is fixedly connected to the diaphragm in the adjacent actuator unit 3. The conduit 301 is connected to an existing air pump through a pipeline, and the movement distance of the valve stem 202 is controlled by the air pressure. Four notches are circumferentially and equidistantly distributed at the lower part of the elastic sleeve 801, which is convenient for the lower part of the elastic sleeve 801 to deform. The elastic sleeve 801 has a certain elasticity, so that in the initial state, the lower part of the elastic sleeve 801 closely adheres to the adjacent valve stem 202, restricting the upward movement of the valve stem 202. When the flowing medium in the valve body 2 impacts the valve block 203 and the valve stem 202, the change in the gap between the valve block 203 and the valve seat 5 is weakened, that is, the relative constancy of the medium flow rate in the valve body 2 is maintained, and the valve block 203 can buffer the impact force of the flowing medium to a certain extent, weakening the erosion suffered by the valve block 203, that is, extending the service life of the valve block 203.

[0040] With reference to Figure 7 and Figure 8 as shown, the trigger assembly includes: a second sliding sleeve 9, slidably arranged on the outer side of the adjacent conduit 301, and a spring is installed between the second sliding sleeve 9 and the adjacent actuator unit 3; a baffle 901, slidably arranged in the adjacent conduit 301 and fixedly connected to the adjacent second sliding sleeve 9, and a plurality of through holes are arranged in the middle of the baffle 901; a connecting frame 902, fixedly connected to the second sliding sleeve 9, and the connecting frame 902 is provided with a triangular guide groove; a second sliding frame 903, slidably arranged on the valve cover 201 and in extrusion cooperation with the adjacent elastic sleeve 801, the second sliding frame 903 is provided with a convex column, and the convex column of the second sliding frame 903 slides in the triangular guide groove of the adjacent connecting frame 902.

[0041] In the above solution, the second sliding sleeve 9 is in sealed sliding fit with the conduit 301. The width of the triangular guide groove on the connecting frame 902 gradually increases from top to bottom. At the same time, under the elastic action of multiple elastic sleeves 801 in the initial state, the convex post of the second sliding frame 903 is located at the uppermost part of the guide groove on the connecting frame 902. At this time, the second sliding frame 903 can also be made to closely adhere to the uppermost part of the guide groove on the connecting frame 902 by setting a spring. The baffle 901 is used to detect the air flow in the conduit 301, so that the elastic sleeves 801 are in different working states under different conditions.

[0042] Specific working process: When controlling the flow of the medium in the valve body 2 through the control cabinet 101, the air pump operates to extract the gas in the execution unit 3 through the conduit 301. When the gas flows, the air pressure in the execution unit 3 becomes smaller. The pressure change in the execution unit 3 will drive the valve stem 202 to move accordingly. At the same time, the spring in the execution unit 3 is compressed. Subsequently, the above operations are repeated to regulate the flow rate of the medium in the valve body 2.

[0043] During the process of gas flowing in the conduit 301, the flowing gas squeezes the baffle 901, causing the baffle 901 to drive the second sliding sleeve 9 and the connecting frame 902 to move together. The movement of the second sliding sleeve 9 compresses the connected spring. The movement of the connecting frame 902 causes the triangular limit groove on it to squeeze the adjacent second sliding frame 903. The movement of the second sliding frame 903 squeezes the adjacent elastic sleeve 801. The elastic sleeve 801 is deformed by the extrusion and moves away from the adjacent valve stem 202, facilitating the free movement of the valve stem 202. After the positions of the valve stem 202 and the valve block 203 are adjusted, the valve stem 202 and the valve block 203 stop moving, and the gas pressure in the execution unit 3 remains stable. At this time, the gas in the conduit 301 no longer flows, that is, the impact force of the gas in the conduit 301 on the baffle 901 disappears. Under the elastic force of the spring connected to the second sliding sleeve 9, the second sliding sleeve 9 and the adjacent connecting frame 902 are reset. Subsequently, the elastic sleeve 801 is deformed and reset in the reverse direction, and the elastic sleeve 801 fits the adjacent valve stem 202 again.

[0044] When the pressure of the flowing medium in the valve body 2 fluctuates greatly, the fluctuating flowing medium impacts the corresponding valve block 203. The valve block 203 and the adjacent valve stem 202 will move upward. However, due to the limiting effect of the elastic sleeve 801 on the valve stem 202, the valve block 203 is hindered from fluctuating reciprocally, avoiding a drastic change in the flow rate of the flowing medium in the valve body 2. At the same time, due to the elastic action of the elastic sleeve 801, the valve block 203 and the valve stem 202 will move slightly, weakening the impact on the valve block 203, thereby extending the service life of this device.

[0045] When it is necessary to block the valve body 2, the operator closes the air pump through the control cabinet 101. Then, the elastic force of the spring in the execution unit 3 is gradually released, causing the valve stem 202 to drive the valve block 203 to move downward and reset. The valve block 203 repeats the above operations to repeatedly block the adjacent valve body 2.

[0046] It should be noted that the above preferred embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
