Description

Technical Field

[0001] This utility model relates to the technical field of oil pipe nozzle mounting base, specifically an oil pipe nozzle mounting base with a sealing gasket. Background Technology

[0002] In the fields of oil extraction, refining, and transportation, tubing nozzles are core components for fluid control and transportation. The sealing and stability of their mounting bases directly affect the efficiency of oil and gas transportation and operational safety. Whether it is the nozzle assembly of the wellhead production tree, the atomizing spray device of the pipeline in the refining workshop, or the diversion nozzle of the oil pipeline, they all need to withstand the dual effects of high pressure, high temperature, and corrosive media for a long time, while also dealing with the risk of structural loosening caused by vibration.

[0003] Traditional tubing nozzle mounting seats have insufficient sealing performance. Most mounting seats rely solely on a single metal contact surface or ordinary rubber gaskets for sealing. Under high pressure and temperature fluctuations, the seals are prone to aging and deformation, and the metal contact surfaces are also prone to wear, directly leading to oil and gas leaks. This can result in resource waste and environmental pollution, or even fires and explosions. Especially during high-pressure wellhead operations, the risk of leakage directly threatens the lives of operators. Furthermore, traditional mounting seats have poor structural stability. Their rotation adjustment mechanisms are often simple bushing fits, lacking fastening and buffering designs. In long-term vibration environments, rotating parts are prone to increased clearance and positioning misalignment, causing the nozzle spray direction to deviate from the preset trajectory, thus reducing production efficiency. Therefore, we propose a tubing nozzle mounting seat with a sealing gasket to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an oil pipe nozzle mounting base with a sealing gasket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil pipe nozzle mounting base with a sealing gasket, comprising an outer nozzle, an inner nozzle mounted on the right side of the outer nozzle, the right side of the inner nozzle fixed to a rotating head, a rotating seat mounted on the right side of the rotating head, the other end of the rotating seat fixed to a nozzle base, and the other end of the nozzle base connected to a connecting base, a connecting hose mounted on the connecting base, a fixing collar fitted to the outer end of the connecting hose, and a hand-tightening bolt screwed onto the fixing collar.

[0006] Preferably, the rotating head is mounted on the rotating seat via a rotating shaft with fastening bolts on the rotating shaft. A rubber ring is fixedly connected below the rotating head, and the other end of the rubber ring is fixed to the inner ring of the rotating seat. The nozzle can be fixed with fastening bolts after the angle is adjusted via the rotating shaft.

[0007] Preferably, the nozzle base has a snap-fit ​​fastener inside the slot, and the upper sealing ring is installed on the nozzle base, and the nozzle base has a corresponding annular groove. The snap-fit ​​fastener design can quickly achieve precise docking between the nozzle base and the connecting base, reducing installation and alignment time.

[0008] Preferably, the connecting base has a snap ring in the slot, and the lower sealing ring is on the connecting base and the connecting base has a corresponding annular groove. The lower sealing ring and the upper sealing ring of the nozzle base can form a complementary mating structure to improve the airtightness of the base connection.

[0009] Preferably, both the nozzle base and the connecting base have corresponding fixing holes, which can be used to further strengthen the connection between the two bases with fasteners such as bolts to resist the influence of equipment vibration on the connection structure.

[0010] Preferably, the connecting hose has an internal anti-wear layer and is coated with an anti-corrosion coating. The hose is connected to the pipe by a fixing collar on the outside. The internal anti-wear layer can resist the damage to the hose caused by long-term fluid erosion, and the anti-corrosion coating can isolate the hose from corrosive media and extend the service life of the connecting hose.

[0011] Preferably, the inner walls of the nozzle base and the connecting base are provided with a ceramic heat insulation coating, which can effectively block the high temperature heat during the fluid transmission process from being transferred to the outside of the nozzle base and the connecting base, and avoid problems such as material aging and strength reduction of the two bases due to long-term contact with high temperature.

[0012] This utility model provides an oil pipe nozzle mounting base with a sealing gasket, which has the following advantages:

[0013] This mounting base adopts a multi-layer sealing design. The nozzle base and the connecting base form a double seal through the upper and lower sealing rings. The rubber ring between the rotating head and the rotating seat specifically seals the rotating parts. The multi-layer sealing structure can tightly fit the gaps between components, effectively resisting high pressure impact, temperature fluctuations and corrosive media erosion, and completely reducing the risk of leakage. This not only avoids resource waste and environmental pollution, but also eliminates the fire and explosion hazards caused by leakage in wellheads, refining workshops and other scenarios, ensuring operational safety.

[0014] The structure is more stable and the problem of easy deviation in traditional rotating mechanisms is solved. The rotating head is mounted on the rotating base through the rotating shaft. With the fastening bolts, the spray angle can be precisely locked to prevent the angle deviation caused by vibration. At the same time, the nozzle base and the connecting base are connected by buckles and buckle rings and reinforced with corresponding fixing holes, which greatly improves the connection firmness, avoids structural loosening caused by long-term vibration, ensures that the nozzle always sprays according to the preset trajectory, ensures the accuracy of fluid delivery, and improves the production efficiency of oil extraction, refining and other processes.

[0015] The connecting hose has an internal anti-wear layer and is coated with anti-corrosion paint to resist fluid erosion and media corrosion. The outside is secured with a fixing collar and hand-tightening bolts, ensuring a tight connection and easy installation and disassembly. The ceramic heat insulation coating on the inner wall of the nozzle base and the connecting base can isolate high-temperature protective components and prevent high temperature damage to the base. The overall structure combines stability and convenience, adapting to oil pipelines of different specifications and coping with high-pressure and high-temperature conditions in various scenarios such as mining and refining, significantly extending service life and reducing equipment maintenance costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: an oil pipe nozzle mounting base with a sealing gasket, including an outer nozzle 1, an inner nozzle 2 installed on the right side of the outer nozzle 1, the right side of the inner nozzle 2 fixed on a rotating head 3, a rotating seat 5 installed on the right side of the rotating head 3, the other end of the rotating seat 5 fixed on a nozzle base 6, and the other end of the nozzle base 6 connected to a connecting base 7, a connecting hose 8 installed on the connecting base 7, a fixing collar 9 fitted on the outer end of the connecting hose 8, and a hand-tightening bolt 10 screwed onto the fixing collar 9.

[0024] The rotating head 3 is mounted on the rotating seat 5 via a rotating shaft 16, and the rotating shaft 16 has a fastening bolt 4. A rubber ring 13 is fixedly connected to the bottom of the rotating head 3, and the other end of the rubber ring 13 is fixed to the inner ring of the rotating seat 5. This structure not only ensures the flexibility of the rotating head 3 when adjusting the spray angle, but also achieves real-time sealing of the rotating parts through the rubber ring 13 to prevent fluid leakage from the rotation gap. At the same time, the fastening bolt 4 can lock the adjusted angle to prevent vibration from causing the spray direction to deviate, further improving the sealing performance and angle control accuracy.

[0025] The nozzle base 6 has a snap fastener 14 fixed inside the snap fastener, and the upper sealing ring 15 is installed on the nozzle base 6. The nozzle base 6 has a corresponding annular groove. The snap fastener 14 can quickly achieve precise docking between the nozzle base 6 and the connecting base 7, reducing the installation alignment time.

[0026] The connecting base 7 has a snap-fit ​​ring 12 inside the slot, and a lower sealing ring 11 is on the connecting base 7, which also has a corresponding annular groove. The lower sealing ring 11 and the upper sealing ring 15 of the nozzle base 6 can form a complementary mating structure, which improves the sealing performance of the connection between the two and ensures that the connecting base 7 and the nozzle base 6 can completely cover the sealing gap after mating, reducing the risk of oil and gas leakage.

[0027] Both the nozzle base 6 and the connecting base 7 have corresponding fixing holes. The corresponding fixing holes can be used to further reinforce the connection between the two bases with fasteners such as bolts, effectively resisting the impact of equipment vibration on the connection structure in oil extraction, refining and other scenarios, preventing long-term vibration from causing the connection between the nozzle base 6 and the connecting base 7 to loosen, ensuring the stability of the overall mounting structure, and avoiding sealing failure or spray deviation caused by loose connection.

[0028] The connecting hose 8 has an internal anti-wear layer and is coated with an anti-corrosion paint. The hose is connected to the pipeline by compression through a fixing collar 9. The internal anti-wear layer of the connecting hose 8 can resist the damage to the hose caused by long-term fluid erosion, and the anti-corrosion paint can isolate the erosion of corrosive media, significantly extending the service life of the connecting hose 8. The compression fixing method of the external fixing collar 9 and the hand-tightening bolt 10 can achieve a tight connection between the connecting hose 8 and the pipeline without complicated tools, which not only improves the interface sealing, but also simplifies the installation and disassembly process and facilitates later maintenance and replacement.

[0029] The inner walls of the nozzle base 6 and the connecting base 7 are provided with a ceramic heat insulation coating. The ceramic heat insulation coating has excellent high temperature resistance and can effectively block the high temperature heat during the fluid transmission process from being transferred to the outside of the nozzle base 6 and the connecting base 7. This prevents the two bases from aging and losing strength due to long-term contact with high temperature. At the same time, it can protect the upper sealing ring 15, lower sealing ring 11 and other components inside the base from the effects of high temperature, extend the service life of the seals, and ensure the stable operation of the mounting base under high temperature conditions.

[0030] Working principle: During operation, the connecting hose 8 is secured to the hand-tightening bolt 10 via the fixing collar 9. Its internal anti-wear layer and anti-corrosion coating ensure fluid delivery and prevent overflow. The fluid flows sequentially through the connecting base 7 and the nozzle base 6, exiting from the inner nozzle 2 and being directionally sprayed out through the outer nozzle 1. The rotating head 3 rotates on the rotating seat 5 via the rotating shaft 16, and the fixing bolt 4 fixes the spray angle. The rubber ring 13 seals the rotating parts. The nozzle base 6 and the connecting base 7 are connected by the snap fastener 14 and snap fastener ring 12. The upper sealing ring 15, the lower sealing ring 11, and the ceramic heat insulation coating on the inner walls of both ensure sealing and heat insulation. The connection is further reinforced by the corresponding fixing holes.
