Abstract
Description
Technical Field
[0001] This application relates to the technical field of diaphragm sheets, and more particularly to diaphragm sheets with fabric. Background Technology
[0002] Diaphragms are widely used in various fluid control equipment, especially in oil-gas separator systems in the automotive industry, where they play an important role. Their main function is to achieve effective separation and sealing of oil and gas under dynamic operating conditions, ensuring the normal operation of the system.
[0003] Traditional diaphragms are prone to stress concentration points due to frequent shape changes during dynamic closing. At the same time, the oil-gas separation system generates a high-temperature environment during operation, which causes thermal shock to the diaphragm.
[0004] Regarding the aforementioned technologies, the diaphragm sheet is prone to tearing and has a shortened service life due to continuous dynamic closing and high-temperature impact, which affects the normal operation of the oil-gas separator system. Utility Model Content
[0005] To improve the strength and high-temperature resistance of the diaphragm sheet, this application provides a diaphragm sheet with fabric.
[0006] The fabric diaphragm sheet provided in this application adopts the following technical solution:
[0007] A fabric diaphragm sheet, including:
[0008] A diaphragm body, wherein the diaphragm body has a disc-shaped structure;
[0009] A fabric interlayer, wherein the fabric interlayer is disposed inside the diaphragm body;
[0010] A fastener is disposed along the outer edge of the diaphragm body and is used to mount the diaphragm body.
[0011] By adopting the above technical solution, a fabric interlayer is incorporated into the diaphragm body, significantly improving the diaphragm's high-temperature resistance and mechanical strength. This effectively prevents diaphragm tearing caused by stress points resulting from dynamic closing and high-temperature impact, extending the product's service life. The fasteners ensure stable installation of the diaphragm body, improving the product's reliability and safety.
[0012] Optionally, the diaphragm body is provided with a plurality of concentric annular protrusions and annular grooves, the annular protrusions and annular grooves being alternately distributed.
[0013] By adopting the above technical solution, multiple concentric annular protrusions and annular grooves are alternately distributed on the diaphragm body. This structural design increases the surface area and structural complexity of the diaphragm body. During dynamic closing, the annular protrusions and grooves can work together to effectively disperse stress, increase the deformation zone of the diaphragm, prevent deflection from occurring only locally, reduce the possibility of tearing, and thus improve the diaphragm life.
[0014] Optionally, the fastener includes:
[0015] A mounting ring is fixedly mounted on the outer edge of the diaphragm.
[0016] The anti-detachment protrusion has a multi-segment arc-shaped structure and is circumferentially fixed on the mounting ring with the center of the mounting ring as the axis.
[0017] By adopting the above technical solution, the mounting ring is fixedly installed on the outer edge of the diaphragm body, providing a structural foundation for the diaphragm to be directly connected to the oil-gas separator. The anti-detachment protrusion is a multi-segment arc structure and is circumferentially arranged on the mounting ring with the center of the mounting ring as the axis. This significantly enhances the anti-detachment performance of the diaphragm after installation, ensures the stability of the diaphragm body, prevents displacement or detachment during dynamic closing, enhances reliability, and increases the convenience of installation while ensuring a firm installation.
[0018] Optionally, the diaphragm body is integrally formed with the mounting ring.
[0019] By adopting the above technical solution, the diaphragm body and the mounting ring are integrally molded, making the overall structure of the diaphragm more stable and reliable. This avoids leakage or damage caused by weak connection points, improving service life and sealing performance. At the same time, it simplifies the production process and reduces manufacturing costs.
[0020] Optionally, the fabric interlayer has pores evenly distributed on it.
[0021] By adopting the above technical solution, the pores in the fabric interlayer allow rubber to permeate into the fabric, thereby enhancing the overall strength and durability of the diaphragm. This effectively prevents diaphragm tearing caused by stress concentration due to dynamic closing and high-temperature impact, improving the product's service life and reliability. Simultaneously, the presence of pores also ensures the diaphragm's flexibility, enabling it to better adapt to various working conditions during use and enhancing the product's overall performance.
[0022] Optionally, an auxiliary protrusion is fixedly installed at the center of the diaphragm body, and the auxiliary protrusion is used to assist in the installation of the diaphragm body.
[0023] By adopting the above technical solution, the protrusion can serve as a clear positioning reference point when installing the diaphragm, making it easier for operators to align the diaphragm with the corresponding installation position on the oil-gas separator. This effectively improves the convenience of diaphragm installation, reduces installation difficulty and time costs, and further enhances overall performance.
[0024] Optionally, the diaphragm body is made of vulcanized rubber.
[0025] By adopting the above technical solution, the vulcanized rubber has excellent elasticity, which allows the diaphragm to adapt well to shape changes during dynamic closing. At the same time, it gives the diaphragm excellent elasticity and sealing performance, improves temperature resistance and anti-aging ability, and ensures that it can maintain good physical and mechanical properties and extend service life when used for a long time in high-temperature environments.
[0026] Optionally, the material of the fabric interlayer is aramid fabric.
[0027] By adopting the above technical solution, using aramid fabric as the interlayer material significantly improves the high-temperature resistance and mechanical strength of the diaphragm. Even under high dynamic conditions, the generated stress can be effectively dispersed, reducing the risk of diaphragm tearing caused by stress concentration, thereby extending the product's service life. Simultaneously, the addition of aramid fabric allows the diaphragm to maintain good physical properties even at high temperatures, further enhancing the product's reliability and stability.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. By adding aramid fabric as a woven interlayer to the diaphragm, the high temperature resistance and tear resistance of the diaphragm are significantly improved. Even under dynamic closing and high temperature impact, the diaphragm can be effectively prevented from tearing due to stress concentration, thereby extending the service life of the diaphragm.
[0030] 2. The integrated molding design of the diaphragm body and the fixing components ensures the stability and sealing reliability of the diaphragm during installation, reduces the risk of leakage caused by improper assembly, and improves the stability and reliability of the overall system.
[0031] 3. The uniform pore design on the fabric interlayer allows the rubber to fully penetrate into the fabric during vulcanization, enhancing the overall strength and durability of the diaphragm while ensuring its flexibility and elasticity to adapt to complex working conditions.

[0040] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0041] This application discloses a fabric diaphragm sheet in its embodiments.
[0042] Reference Figure 1The fabric diaphragm includes a diaphragm body 1, a fabric interlayer 2, and a fastener 3. The diaphragm body 1 has a disc-shaped structure, the fabric interlayer 2 is disposed inside the diaphragm body 1, and the fastener 3 is disposed on the outer edge of the diaphragm body 1. The fastener 3 is used to install the diaphragm body 1.
[0043] When in use, take the fabric diaphragm sheet to the vicinity of the installation position of the oil-gas separator, match the fixing part 3 with the corresponding installation structure on the oil-gas separator, and press to make the fixing part 3 fit tightly with the oil-gas separator to complete the installation.
[0044] Reference Figure 2 and Figure 3 The diaphragm body 1 is provided with multiple concentric annular protrusions 11 and annular grooves 12, which are alternately distributed.
[0045] During operation, the opening and closing of valves in the oil-gas separator system will cause the diaphragm 1 to frequently undergo dynamic closing. When the diaphragm 1 is squeezed or stretched, the annular protrusion 11 and the annular groove 12 act as a buffer to evenly distribute the stress, avoiding stress concentration that could cause the diaphragm 1 to tear, and enhancing the structural stability of the diaphragm 1 during frequent deformation.
[0046] Reference Figure 1 The fastener 3 includes a mounting ring 31 and an anti-detachment protrusion 32. The mounting ring 31 is fixedly installed on the outer edge of the diaphragm body 1. The anti-detachment protrusion 32 has a multi-segment arc structure and is circumferentially fixed on the mounting ring 31 with the center of the mounting ring 31 as the axis. The diaphragm body 1 and the mounting ring 31 are integrally formed.
[0047] During use, push the diaphragm body 1 along with the mounting ring 31 towards the installation position of the oil-gas separator, so that the mounting ring 31 begins to contact the corresponding structure on the oil-gas separator. Continue to push the diaphragm body 1 until the mounting ring 31 is fully embedded in the installation position of the oil-gas separator, achieving a tight fit. During the installation process, the anti-detachment protrusion 32 will form an effective locking action with the corresponding structure inside the oil-gas separator, ensuring that the diaphragm will not accidentally fall off due to external forces such as vibration and airflow impact during the operation of the oil-gas separator.
[0048] Reference Figure 2 An auxiliary protrusion 4 is fixedly installed at the center of the diaphragm body 1. The auxiliary protrusion 4 can be used as a force point for installation or disassembly, and at the same time assists in the initial positioning during installation. The diaphragm body 1 is installed into the oil-gas separator with the auxiliary protrusion 4 as the reference.
[0049] Reference Figure 2 and Figure 3The fabric interlayer 2 is made of aramid fabric with uniformly distributed pores. The membrane body 1 is made of vulcanized rubber. The prepared aramid fabric interlayer 2 with uniform pores is placed in a predetermined position inside the vulcanized rubber membrane body 1. Composite processes such as hot pressing can be used to tightly bond the two together. The processing technology is not specifically limited in this embodiment. The goal is to ensure that the bond between the aramid fabric and the vulcanized rubber is strong and that there is no delamination or degumming, thereby forming a complete fabric diaphragm structure.
[0050] The implementation principle of the fabric diaphragm in this embodiment is as follows: the auxiliary protrusion 4 at the center of the diaphragm body 1 is used for installation and positioning, so that the diaphragm can be accurately installed in the oil-gas separator. After installation, the auxiliary protrusion 4 can stabilize the center position of the diaphragm body 1 and share the stress during operation. The diaphragm body 1 is made of vulcanized rubber, which utilizes its excellent elasticity and flexibility to adapt to dynamic closing. It can quickly return to its original shape during frequent shape changes to prevent damage. Its good sealing performance can tightly fit with the contact parts under different pressures to prevent oil and gas leakage. The diaphragm body 1 also has strong corrosion resistance and a certain degree of high temperature resistance, which can resist the erosion of oil and gas components and impurities and the influence of high temperature environment, ensuring normal operation under complex working conditions.
[0051] The fabric interlayer 2 is made of aramid fabric with uniformly distributed pores. The high strength and high modulus of the aramid fabric enhance the overall tear resistance of the diaphragm and share the stress during dynamic closing. Its excellent heat resistance and chemical stability can resist high temperature impact and oil and gas chemical corrosion, maintaining performance and life.
[0052] The fastener 3 includes an mounting ring 31 and an anti-detachment protrusion 32. The mounting ring 31 is integrally formed with the outer edge of the diaphragm body 1, ensuring connection strength and structural integrity. The mounting ring 31 is used to install the diaphragm onto the oil-gas separator. The anti-detachment protrusion 32 is circumferentially arranged with the center of the mounting ring 31 as the axis, which can prevent the diaphragm from accidentally falling off under vibration, impact, or other conditions during the operation of the oil-gas separator, ensuring the stable installation of the diaphragm in the oil-gas separator. The annular protrusions 11 and annular grooves 12 on the diaphragm body 1 are alternately distributed, changing the oil-gas flow path and promoting oil-gas separation. At the same time, they disperse stress, enhance structural stability, and improve sealing effect during dynamic closing. These structures work together to enable the fabric diaphragm to operate efficiently and stably in oil-gas separation and other systems.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
