Description

Technical Field

[0001] The utility model relates to the field of pressure vessels, in particular to a clamp-type valve body installation structure for pressure vessels. Background Art

[0002] Existing pressure vessel valve body installation structures usually have problems such as complex installation, difficult maintenance and complex manufacturing process.

[0003] When installing valves in existing pressure vessels, the valves are usually fixed by threaded connection. This method requires opening threaded holes on the pressure vessel. However, for some non-metallic pressure vessels, threaded holes cannot be opened directly. Some metal parts need to be embedded in advance and threaded holes need to be opened in the metal parts. The embedded metal parts must have a certain thickness to ensure the number of threads so that the valve body and the embedded parts are firmly connected. Figure 1 The non-metallic pressure vessel shown in the figure has a liner 02 and a winding layer 03 made of non-metallic materials, and a metal valve seat 04 is pre-buried inside the annular pressure vessel 01. Figure 2 As shown, the carbon fiber spindle 05 is wound on the annular pressure vessel 01, and enters the inner rotation position 07 from the outer rotation position 1 06 to form the carbon fiber winding track 08. In the winding process, since the outer diameter of the container is not large, in order to make the annular pressure vessel store more gas, the inner diameter can only be reduced. However, in order to make the carbon fiber winding process uninterrupted, the spindle size will be larger, and the inner diameter must be larger than the spindle size, and the internal space must allow the spindle to have a certain deflection angle. If the valve seat is embedded in advance, the protruding part will not only occupy the space of the inner circle of the container, but also make the winding path difficult.

[0004] In addition, pressure vessels require regular inspection and maintenance, and the traditional bolt connection method has low installation efficiency and inconvenient disassembly. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a clamp-type valve body installation structure for a pressure vessel, aiming to overcome the above-mentioned defects in the prior art, which can not only ensure the convenient disassembly of the valve body, but also simplify the winding process, and can reduce the inner ring diameter of the container to hold more gas.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A clamp-type valve body installation structure for a pressure vessel, comprising a valve body, a connecting belt and a belt adjustment component. The inner side of the valve body is closely arranged against the outer wall of the inner ring of the pressure vessel. Both ends of the valve body are respectively connected to a section of the connecting belt. The connecting belt extends around the outer wall of the inner ring of the pressure vessel. The free ends of the two sections of the connecting belt are connected through the belt adjustment component, and the belt adjustment component is used to adjust the tightness of the connecting belt so that the valve body is in close contact with the pressure vessel.

[0008] As a further implementation method, the valve body is installed on a pin shaft seat, and first pin shafts are respectively embedded at both ends of the pin shaft seat. The fixed end of the connecting belt is fixedly connected to the first pin shaft.

[0009] As a further implementation method, the pin shaft seat and the valve body are integrally processed, which is convenient for processing and forming, and has better structural stability.

[0010] As a further implementation method, the belt adjustment component includes a second pin shaft with holes, a bolt and a locking nut. Two second pin shafts are provided, and the two second pin shafts are respectively connected to the two sections of the connecting belt. The bolt passes through the two second pin shafts, and the locking nut is tightly connected to the bolt on the outer side of the second pin shaft.

[0011] As a further implementation method, the connecting belt is fixedly connected to the second pin shaft, and the locking nut abuts against the second pin shaft to limit the connecting belt to a specific length.

[0012] As a further implementation method, the connecting belt is made of a metal material or is fabricated from a metal material, which can fix the valve body on the outer wall of the pressure vessel without pre-burying a valve seat.

[0013] As a further implementation method, a sealing member is further provided between the valve body and the outer wall of the pressure vessel to ensure that there is no leakage at the container interface.

[0014] As a further implementation method, a sealing member groove is formed on the inner side of the valve body, and the sealing member is arranged in the sealing member groove to further ensure the sealing performance.

[0015] As a further implementation method, the sealing member adopts a rubber sealing gasket.

[0016] As a further implementation method, the valve body is made of a high-strength metal material to ensure stability and durability in a high-pressure and high-temperature environment.

[0017] Adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] 1. The utility model forms a clamp - type connection structure through a connecting belt and a belt adjustment component to install the valve body at the inner ring of the pressure vessel. This not only facilitates installation and disassembly, but also simplifies the carbon fiber winding process. The inner diameter of the pressure vessel can be smaller, enabling it to hold more gas and optimizing the overall structure of the pressure vessel.

[0019] 2. The connection structure of the utility model enables non - metallic pressure vessels to install valves without pre - embedding valve seats with threaded holes, simplifying the manufacturing process of pressure vessels and improving the installation and disassembly efficiency of valves.

[0033] Embodiment 1

[0034] In a typical embodiment of the present application, a clamp-type valve body installation structure for a pressure vessel is provided. As Figures 3 - 7 shown, it includes a valve body 11, a connecting belt 15, and a belt adjustment assembly. The inner side of the valve body 11 is closely attached to the outer wall of the inner ring of the pressure vessel. Both ends of the valve body 11 are respectively connected to a section of the connecting belt 15. The connecting belt 15 extends around the outer wall of the pressure vessel. The free ends of the two sections of the connecting belt are connected through the belt adjustment assembly. The belt adjustment assembly is used to adjust the tightness of the connecting belt so that the valve body is in close contact with the pressure vessel.

[0035] As Figure 5 shown, this embodiment is designed based on an annular pressure vessel. The clamp-type valve body installation structure of this embodiment is installed at the inner ring position of the annular pressure vessel 01. The inner side of the valve body 11 is closely attached to the outer wall of the inner ring, thereby realizing the portable installation of the valve body on the annular container. The annular container of this embodiment is made of a metal material or a non-metal material and can store gas or liquid at a certain pressure. Of course, in other embodiments, such a clamp-type installation structure can also be applied to valve body installation on pressure vessels of other shapes as long as the sealing between the valve body and the container is ensured.

[0036] Specifically, as Figures 3 - 4As shown in the figure, the valve body 11 is in contact with the outer wall of the container through two connecting bands 15 with elasticity or elongation amount that surround the annular container. To further ensure the tight contact and fixation between the valve body and the container, the two connecting bands are connected by a band adjustment assembly, which can adjust the tightness of the connecting bands according to the sizes of different containers, so as to ensure that the elongation amount of the connecting bands is sufficient to make the inner side of the valve body in close contact with the annular container and ensure the normal operation of the valve body. Among them, if the connecting band is made of a metal material, it is a thin metal band with a certain amount of stretchability; if it is made of a non-metal material, a material with elasticity and toughness is used. In this embodiment, the connecting band is made of carbon fiber material, which has high strength and good toughness, and can fix the valve body on the outer wall of the pressure vessel without pre-burying a valve seat.

[0037] Specifically, as Figure 6 shown, the valve body 11 is installed on the pin shaft seat 12, and the pin shaft seat 12 is integrally processed with the valve body 11, which is convenient for processing and forming and also makes the structural stability better. The valve body 11 is located at the central part of the pin shaft seat 12, and the first pin shafts 13 are respectively embedded at both ends of the pin shaft seat 12. The pin shaft seat provides a supporting function for the first pin shafts, and the two first pin shafts 13 are respectively connected to the fixed ends of the two connecting bands 15.

[0038] Specifically, as Figure 7 shown, the band adjustment assembly includes second pin shafts 16 with holes, bolts 17 and lock nuts 18. Among them, two second pin shafts 16 are provided, and through holes are opened on each second pin shaft 16. The two second pin shafts 16 are respectively fixedly connected to the free ends of the two connecting bands 15, and the bolts 17 pass through the through holes of the two second pin shafts 16 to connect them, thereby realizing the connection of the two connecting bands. The lock nuts 18 are tightly connected to the bolts 17 on the outer sides of the two second pin shafts 16, and the lock nuts 18 are in contact with the second pin shafts 16 to limit the connecting bands to a specific length; by adjusting the relative positions of the two lock nuts, the tightness of the connecting bands can be changed, which is convenient for the installation and disassembly of the valve body.

[0039] In addition, as Figure 4 、 6 shown, a sealing member 14 is further provided between the valve body 11 and the outer wall of the annular pressure vessel to ensure that there is no leakage at the container interface. Specifically, a sealing member groove is opened on the contact surface between the inner side of the valve body 11 and the annular container, and the sealing member 14 is arranged in the sealing member groove to further ensure the sealing performance of the interface. In this embodiment, the sealing member is a rubber sealing washer.

[0040] In addition, in this embodiment, the main body part of the valve body is made of high-strength metal materials such as stainless steel and alloy steel to ensure the stability and durability of the valve body in high-pressure and high-temperature environments.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it. Those of ordinary skill in the art should understand that the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
