Description

Technical Field

[0001] This utility model relates to the field of hydraulic auxiliary components, specifically to a composite welded diaphragm accumulator. Background Technology

[0002] A diaphragm accumulator is an energy storage device that uses a deformable diaphragm to isolate gas (usually nitrogen) from hydraulic oil. Its core components are the diaphragm and the housing. Existing diaphragm accumulators typically employ a single-layer housing with a rubber diaphragm, which is pressed between the upper and lower parts of the housing by a peripheral pressure ring. However, the two sets of housings are usually connected by a single circumferential weld. The butt joint design of the two sets of housings is prone to relative rotation or even displacement during welding. Inadequate contact between the mating surfaces can reduce weld uniformity, increase the risk of later cracking, and decrease the overall structural stability. Utility Model Content

[0003] The purpose of this invention is to provide a composite welded diaphragm accumulator that ensures a stable and close fit between the upper and lower shells, thereby improving the stability, efficiency, and quality of the welding process. Furthermore, by combining the circumferential weld and the clamping plate with the composite welding process, the connection stability of the overall structure of this composite welded diaphragm accumulator during the initial welding stage and the connection effect of the overall structure during subsequent use can be further improved.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A composite welded diaphragm accumulator includes an upper shell with an air valve, a lower shell with a drain port, and a diaphragm located between the upper and lower shells to form a diaphragm accumulator body. The upper and lower shells are connected by multiple sets of first and second protrusions respectively. The diaphragm accumulator body is provided with multiple sets of clamping plates that are detachably connected to the first and second protrusions respectively through the upper and lower shells.

[0006] Preferably, the diaphragm is provided with a pressure ring, and the pressure ring has multiple sets of grooves for securing the card plate.

[0007] Preferably, the upper and lower housings along the direction of the first and second convex plates are respectively provided with slots, and multiple sets of second clamping plates are detachably connected to the first and second convex plates passing through the slots.

[0008] Preferably, the upper and lower housings, which correspond to the positions of the multiple sets of card plates and the second card plate respectively, are provided with multiple sets of connecting plates, and connecting members are provided between the connecting plates and the card plates and the second card plate.

[0009] Compared with the prior art, this utility model has the following advantages and effects:

[0010] This utility model is a composite welded diaphragm accumulator. Compared with the traditional diaphragm accumulator structure, the upper and lower shells of this accumulator can be connected and locked in place by multiple sets of first and second protrusions within the limiting groove during the docking process. This ensures the stability of their relative positions and prevents relative rotation during subsequent welding. Simultaneously, the locking action of the locking plates ensures that the upper and lower shells remain in a stable and close fit, preventing vertical displacement during subsequent welding that could lead to inconsistent weld size. This further improves the stability and efficiency of the welding process, as well as the corresponding weld quality. Furthermore, it can be used to... According to the installation requirements, after the circumferential weld is completed, multiple sets of stably pluggable plates can be welded to the corresponding walls of the upper and lower shells. The welding method of the plates can be spot welding at the main connection points according to the connection requirements to ensure that they will not easily fall off. The combined welding process of the circumferential weld and the plates can further improve the connection stability of the overall structure of this composite welded diaphragm accumulator in the early stage of welding and the connection effect of the overall structure in subsequent use. It can effectively improve the welding uniformity of the circumferential weld, thereby reducing the risk of subsequent cracking, and can appropriately extend its service life, improve its applicability and practicality.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] See Figure 1-3This embodiment relates to a composite welded diaphragm accumulator, comprising an upper shell 1 with an air valve 10, a lower shell 2 with a drain port 20, and a diaphragm 3 disposed between the upper shell 1 and the lower shell 2, forming a diaphragm accumulator body 100. The upper shell 1 and the lower shell 2 are connected by multiple sets of first protrusions 4 and second protrusions 5 disposed thereon. The diaphragm accumulator body 100 is provided with multiple sets of clamping plates 6 that are detachably connected to the first protrusions 4 and the second protrusions 5 respectively through the upper shell 1 and the lower shell 2.

[0017] Specifically in this embodiment, such as Figure 1 The overall structure of this type of composite welded diaphragm accumulator shown can be combined with the initial installation. Figure 2 and Figure 3 As shown, the diaphragm 3 can be embedded and fixed by connecting structures such as the pressure ring 30 on its upper ring, combined with the first and second grooves respectively provided on the inner walls of the upper shell 1 and the lower shell 2. The first convex plate 4 and the second convex plate 5 can act on the corresponding connecting wall surfaces of the upper shell 1 and the lower shell 2 respectively to form an integral structure with the corresponding shell. The first convex plate 4 and the second convex plate 5 can be set in the shape of... according to the connection requirements. Figure 2For example, multiple sets of staggered arrangements are used. Simultaneously, the corresponding connecting surfaces of the upper shell 1 and the lower shell 2 are provided with multiple sets of limiting grooves 101 adapted to the sliding of the first protruding plate 4 and the second protruding plate 5. Both the first protruding plate 4 and the second protruding plate 5 have connecting grooves 102 for the insertion of the retaining plate 6. The outer walls of both the upper shell 1 and the lower shell 2 have second limiting grooves 103 for the insertion of the retaining plate 6 and connected to the limiting grooves 101. Furthermore, a retaining groove 104 is provided on the corresponding wall surface on the other side of the limiting groove 101, corresponding to the position of the second limiting groove 103. During subsequent docking of the upper shell 1 and the lower shell 2, the multiple sets of first protruding plates 4 and second protruding plates 5 can be positioned within the multiple sets of limiting grooves 101 at corresponding positions. The upper housing 1 and the lower housing 2 are slidably inserted into each other. Combined with the positions of the second limiting groove 103 and the slot 104 located on both sides of the limiting groove 101, when the mating walls between the upper housing 1 and the lower housing 2 are in a stable mating state, the connecting groove 102 of the first protruding plate 4 and the second protruding plate 5 is flush with the second limiting groove 103 and the slot 104. Then, the slot 6 is inserted and locked in sequence through the second limiting groove 103 and the limiting groove 101 and placed in the slot 104. After multiple sets of slot 6 are inserted in sequence, the initial installation process of this diaphragm accumulator body 100 is completed. Subsequently, the circumferential weld seam is welded at the corresponding position between the upper housing 1 and the lower housing 2. Compared to the traditional diaphragm accumulator structure, the main body 100 of this type of diaphragm accumulator features an upper shell 1 and a lower shell 2 that, during docking, can be secured by multiple sets of first protruding plates 4 and second protruding plates 5 inserted into the limiting groove 101. This ensures the stability of their relative positions and prevents relative rotation during subsequent welding. Furthermore, the locking action of the clamping plate 6 ensures that the upper shell 1 and lower shell 2 remain in a stable, close-fitting docking state, preventing vertical displacement during subsequent welding that could lead to inconsistent weld size. This further improves the stability and efficiency of the welding process, as well as the corresponding weld quality. Moreover, it can be customized according to installation requirements. After the circumferential weld is completed, multiple sets of clamping plates 6 can be stably welded to the corresponding wall surfaces of the upper shell 1 and the lower shell 2. The welding method of the clamping plates 6 can be spot welding according to the connection requirements to ensure that the main connection points are not easily detached. The combined welding process of the circumferential weld and the clamping plates 6 can further improve the connection stability of the overall structure of this composite welded diaphragm 3 accumulator in the early stage of welding and the connection effect of the overall structure in subsequent use. It can effectively improve the welding uniformity of the circumferential weld, thereby reducing the risk of subsequent cracking, and can appropriately extend its service life, improve its applicability and practicality.

[0018] The diaphragm 3 is provided with a pressure ring 30, and the pressure ring 30 has multiple sets of grooves 301 for locking the locking plate 6. Specifically, according to the usage requirements, the locking groove 104 for locking the locking plate 6, which is located on one side of the limiting groove 101 and corresponding to the position of the second limiting groove 103, can be set as a through groove, so that the locking plate 6 can pass through the second limiting groove 103, the connecting groove 102 and the locking groove 104 set as a through groove in sequence, thereby fixing the diaphragm 3 in the diaphragm accumulator body 100. The groove 301 at the corresponding position of the ring 30 is used for fitting and locking. During the initial installation, the position of the diaphragm 3 and its upper pressure ring 30 between the upper housing 1 and the lower housing 2 is adjusted by rotation to allow the locking plate 6 to be inserted and locked. The locking plate 6 connected to the diaphragm 3 in this way can further improve the positional stability of the diaphragm 3 inside the diaphragm accumulator body 100. It is less likely to rotate or shift position during use, thus improving the stability of this composite welded diaphragm 3 accumulator.

[0019] The upper housing 1 and lower housing 2, along the direction in which the first convex plate 4 and the second convex plate 5 pass through, are respectively provided with slots 105. Multiple sets of second retaining plates 7 are detachably connected to the first convex plate 4 and the second convex plate 5 passing through the slots 105. Specifically, the slots 105 can be made on the corresponding wall surfaces of the upper housing 1 and the lower housing 2 on one side of the limiting groove 101 according to usage requirements. When the upper housing 1 and the lower housing 2 are docked, the first convex plate 4 and the second convex plate 5, located within the limiting groove 101, can be combined with the second connecting grooves 106 corresponding to those within the slots 105, forming the second connecting grooves 106. During the insertion and engagement process of the second locking plate 7, combined with the opening height setting of the slot 105, in the state where the locking plate 6 is not installed, the upper shell 1 and lower shell 2, which are connected to each other, can move up and down slightly within the slot 105 by the second locking plate 7 inserted into the second connecting slot 106 on the first protruding plate 4 and the second protruding plate 5. When the locking plate 6 is inserted and installed, making the upper shell 1 and lower shell 2 stably connected, its side wall can fit against the bottom wall of the first protruding plate 4 and the second protruding plate 5, which is set according to the opening position of the slot 105. This facilitates the initial connection of the first protruding plate 4 and the second protruding plate 5. The insertion position of the second protruding plate 5 within the limiting groove 101 is determined and adjusted to further improve the convenience and efficiency of docking operations between the upper housing 1 and the lower housing 2. Furthermore, when the housing of this diaphragm accumulator body 100 needs to be opened for subsequent recycling, multiple sets of clamping plates 6 can be disassembled beforehand using hammering or chiseling. Then, the corresponding end faces of the second clamping plates 7 at the corresponding positions can be disassembled sequentially using hammering or chiseling along the direction that allows the circumferential weld to separate, enabling the first protruding plate 4 or the second protruding plate 5 to slide out an appropriate distance within the limiting groove 101. This creates a gap between the upper shell 1 and the lower shell 2, allowing multiple sets of second clamping plates 7 to separate within the second connecting grooves 106 on the first protruding plate 4 and the second protruding plate 5. The first protruding plate 4 and the second protruding plate 5 can then slide completely out within the limiting groove 101, achieving a complete separation between the upper shell 1 and the lower shell 2. Compared to directly hammering and chiseling the circumferential weld between the upper shell 1 and the lower shell 2 to separate them, this method can appropriately reduce the damage to the upper shell 1 and the lower shell 2, appropriately reduce the usage cost, and appropriately increase the subsequent recycling value.

[0020] Multiple sets of connecting plates 8 are provided on the upper housing 1 and lower housing 2, which correspond to the positions of the multiple sets of clamping plates 6 and the second clamping plate 7, respectively. Connecting members 9 are provided between the connecting plates 8 and the clamping plates 6 and the second clamping plate 7. (See details...) Figure 4As shown, the connector 9 can be designed with a bolt rod structure, through which the first through hole 60 and the second through hole 70 are respectively opened at the corresponding positions of the clamping plate 6 and the second clamping plate 7, and in conjunction with the threaded hole opened at the corresponding position of the connecting plate 8, a detachable connection process is achieved by rotation. Thus, after welding is completed, the connector 9 is added to facilitate disassembly and assembly, and can further improve the connection stability of the clamping plate 6 and the second clamping plate 7 on the first convex plate 4 or the second convex plate 5, thereby improving the operational stability of this composite welded diaphragm 3 accumulator.
