Description

TECHNICAL FIELD

[0001] The utility model relates to an industrial valve, in particular to a valve body of an industrial valve. BACKGROUND

[0002] This part provides background information related to the utility model, which does not necessarily constitute the prior art.

[0003] In the air conditioning industry, especially in the field of vehicle-mounted air conditioners, industrial valves are usually used to control the flow of refrigerant and gas in the air conditioner. Using industrial valves can achieve the purpose of preventing fluid backflow and maintaining the pressure in the space.

[0004] The valve body of the industrial valve in the prior art usually includes a body and a bolt connection part, the valve core and the flow rate control element can be accommodated in the body, and the body can be attached to other fixed parts in the air conditioner by means of the bolt connection part and fastening tools such as bolts to fix the valve body in place relative to the internal space of the air conditioner. However, in the prior art, the valve body is usually prepared separately, for example, two bolt connection parts are prepared and further attached to the body, which is complex in preparation process and requires high operation of workers, prolonging the preparation period of the product and increasing the cost of individual products. Further, the demand for weight reduction of products is increasing, especially in the automotive industry, and people also expect to produce lighter industrial valves. The above problems are to be solved. SUMMARY

[0016] Preferably, the valve body further comprises at least three circumferential auxiliary ribs extending in a circumferential direction on an outer circumferential surface of the combination of the body and the attachment mechanism, the at least three circumferential auxiliary ribs being arranged spaced apart from each other in an axial direction of the valve body between the first axial end reinforcing rib and the second axial end reinforcing rib.

[0017] Preferably, an outer diameter of an axial middle section of the body is smaller than an outer diameter of the first end and an outer diameter of the second end of the body, one of the at least three circumferential auxiliary ribs being arranged corresponding to a position of the body having the smallest outer diameter.

[0018] Preferably, the valve body further comprises at least two axial auxiliary ribs extending in an axial direction of the valve body from the first axial end reinforcing rib to the second axial end reinforcing rib on an outer circumferential surface of the combination of the body and the attachment mechanism, the at least two axial auxiliary ribs being arranged spaced apart from each other in a circumferential direction of the combination of the body and the attachment mechanism, wherein at least one of the axial auxiliary ribs is provided on the outer circumferential surface of the body and on the outer circumferential surface of the attachment mechanism.

[0028] Now we will combine the appendix Figures 1 to 5 A preferred embodiment of the valve body of this invention will be described in detail below. The following description is exemplary in nature and is not intended to limit the invention or its application or use.

[0029] Certain directional terms used herein (including the claims) should be understood to have normal meaning and refer to those directions involved when normally observing the drawings, but not necessarily the orientation of the valve body according to the present invention in actual use.

[0030] Figure 1 and Figure 2 A perspective view of the valve body 100 viewed from different angles is shown. The valve body 100 is configured to include a body 1 and an attachment mechanism 2. A valve core (not shown in the figures) can be housed within the body 1 to control the flow of fluid, such as refrigerant or compressed gas, through the body 1. In some cases, a flow rate control element 6 can also be housed within the body 1 to provide more flexible control over the fluid flow, as needed. The attachment mechanism 2 is designed to be fixedly connected to the body 1 in a radial direction R. The body 1 can be attached to a fixed component, such as in an air conditioner, by means of the attachment mechanism 2 and fastening tools (e.g., bolts, not shown in the figures), to secure the body 1 relative to the interior space of the air conditioner.

[0031] The configuration of the main body 1 and the attachment mechanism 2 will be described in detail below.

[0032] The body 1 is configured as a cylinder extending continuously along the first axis L1. In particular, the body 1 comprises a first end 11 and a second end 12 arranged axially opposite to each other, and a first channel 13 extending continuously through the body 1 from the first end 11 to the second end 12, in which the valve core and the flow rate control element 6 described above can be accommodated. An inflow pipe and an outflow pipe (not shown) can be fluid-tightly connected to the first end 11 and the second end 12, respectively. For example, the inflow pipe and the outflow pipe can be engaged with the first end 11 and the second end 12, respectively, in a manner of interference fit.

[0033] In one case, the diameter of the outer circumferential surface of the body 1 along the first axis L1 can not be a constant value. In particular, referring to Figure 1 , the outer diameter of the axially intermediate section of the body 1 can be smaller than the outer diameter of the first end 11 and the outer diameter of the second end 12. In this way, material can be further saved, and the manufacturing cost can be reduced.

[0034] In combination with Figure 2 and Figure 3 , wherein, Figure 3 a left view of the valve body 100 is shown. The body 1 can comprise an accommodation portion 14 located in the first channel 13, in which the valve core and the flow rate control element 6 can be fixedly arranged. In particular, the accommodation portion 14 is configured as a step extending radially inwardly (i.e. towards the first axis L1) from the position of the axially intermediate section of the inner circumferential wall of the first channel 13. The accommodation portion 14 has a third channel 141 also extending through along the first axis L1, in which the valve core and the flow rate control element 6 will be arranged in particular, the third channel 141 should be sized to at least allow the valve core and, if necessary, the flow rate control element 6 to be conformably accommodated therein.

[0035] The attachment mechanism 2 is configured as a cylinder extending continuously along the second axis L2 on one side of the body 1. In particular, the attachment mechanism 2 comprises a third end 21 and a fourth end 22 arranged axially opposite to each other, and a second channel 23 extending continuously through the attachment mechanism 2 from the third end 21 to the fourth end 22.

[0036] In one case, when the fastening tool is a bolt, an inner thread (not shown) can be provided on the inner peripheral wall of the second passage 23 to match the outer thread shape of the bolt to allow the fastening tool to be threadedly connected to the inner peripheral wall of the second passage 23. In one preferred case, the inner thread can be provided at least on the section of the inner peripheral wall of the second passage 23 near the third end 21 and the section near the fourth end 22, at which time two short bolts can be used to extend into the second passage 23 from the third end 21 and the fourth end 22, respectively, to be screw-connected with the corresponding inner thread, thereby achieving two-end locking. Of course, it should be understood by those skilled in the art that although the desired good fixing effect can not be achieved, the effect of fixing the valve body to the fixing component in the air conditioner by means of the bolt can also be achieved by providing the inner thread at only one end of the inner peripheral wall of the second passage or at only the middle position.

[0037] In another case, no thread or other connecting structure can be provided on the inner peripheral wall of the second passage 23. At this time, one long bolt can be used to pass through the entire second passage 23, thereby achieving one-end locking.

[0038] As can be seen from the above analysis, the valve body 100 according to the present application can achieve one-end locking by means of one long bolt, or two-end locking by means of two short bolts, which is more flexible than the use mode of the prior art.

[0039] In this document, the first axis L1 and the second axis L2 can extend parallel to each other. This design is beneficial for the compact arrangement of the valve body 100, and also facilitates accurate positioning of the body 1. Of course, it should be understood by those skilled in the art that even in the case where the first axis L1 and the second axis L2 are not parallel to each other, the purpose of connecting the body 1 to the fixing component in the air conditioner, for example, by means of the attachment mechanism 2 and the fastening tool can be achieved. In addition, those skilled in the art can also understand that in the case where the first axis L1 is parallel to the second axis L2, the "axial direction of the valve body" mentioned hereinafter should be regarded as the orientation parallel to the first axis L1 and the second axis L2, and the "radial direction of the valve body" is consistent with the radial direction of the body.

[0040] In the case where the first axis L1 is parallel to the second axis L2, it is preferred that the end face of the first end 11 of the body 1 and the end face of the third end 21 of the attachment mechanism 2 are located on one plane, and the end face of the second end 12 of the body 1 and the end face of the fourth end 22 of the attachment mechanism 2 are located on another plane, and the above two planes should extend along the radial direction of the valve body. This design is further beneficial for the compact arrangement of the valve body 100, and simplifies the preparation process of the valve body 100.

[0041] When the valve body 100 is made of metal material, the body 1 and the attachment mechanism 2 can be separately manufactured, and then the attachment mechanism 2 is fixed to the outer circumferential surface of the body 1 in the radial direction of the body 1 by means of welding or adhesion, etc. Compared with the prior art, by designing the attachment mechanism 2 to have a continuously extended configuration along the second axis L2, the number of components included in the valve body 100 is reduced, and the manufacturing and installation steps are simplified, and the design of the valve body 100 is simplified. Of course, it is also possible to consider that the valve body 100 is integrally formed by means of a casting process, etc.

[0042] Alternatively, the valve body 100 can also be formed in one piece by means of injection molding process using engineering plastic, so that the body 1 and the attachment mechanism 2 are formed in one piece. The engineering plastic can be any suitable engineering plastic known in the art, including but not limited to the five general-purpose engineering plastics of polyamide, polycarbonate, polyformaldehyde, modified polyphenylene ether and thermoplastic polyester, as well as polyimide, polyphenylene sulfide, polysulfone, aromatic polyamide, polyarylate, polyphenyl ester, polyaryletherketone, liquid crystal polymer and fluororesin, etc.

[0043] On the one hand, since the density of plastic material is lower than that of metal material, the total weight of the valve body 100 can be reduced. On the other hand, the injection molding process is easy to manufacture, no secondary machining and subsequent processing work is needed, mass production can be realized, production efficiency is improved, and the cost of single piece is reduced.

[0044] In order to further enhance the structural strength of the entire valve body 100 (especially when the valve body 100 is made of plastic), the valve body 100 can also be provided with a plurality of reinforcing ribs / auxiliary ribs. When the body 1 and the attachment mechanism 2 connected together or integrally formed are regarded as a whole (hereinafter referred to as the combination of the body 1 and the attachment mechanism 2), the reinforcing ribs / auxiliary ribs can be selectively arranged on the outer circumferential surface and the axial end of the combination of the body 1 and the attachment mechanism 2.

[0045] In particular, continuing to refer to Figures 1 to 3The plurality of reinforcing ribs / auxiliary ribs can include a shaft end reinforcing rib assembly 3. The shaft end reinforcing rib assembly 3 includes a first shaft end reinforcing rib 31 and a second shaft end reinforcing rib 32 protruding radially outward from both ends of the combination of the body 1 and the attachment mechanism 2. In one case, the first shaft end reinforcing rib 31 can surround and connect the first end 11 of the body 1 and the third end 21 of the attachment mechanism 2. In another case, the first shaft end reinforcing rib 31 can be a portion extending radially from the first end 11 of the body 1 towards the third end 21 of the attachment mechanism 2 until abutting to the third end 21 of the attachment mechanism 2. Since the inner diameter of the first passage 13 is usually larger than the inner diameter of the second passage 23, the first shaft end reinforcing rib 31 is preferably designed to extend in a tapered configuration from the first end 11 of the body 1 towards the third end 21 of the attachment mechanism 2, so as to achieve the purpose of smoothly connecting both the first end 11 of the body 1 and the third end 21 of the attachment mechanism 2.

[0046] Similarly, the second shaft end reinforcing rib 32 can also surround or directly extend from the second end 12 to the fourth end 22 of the body 1 and the attachment mechanism 2, so as to smoothly connect both the second end 12 and the fourth end 22. See especially Figure 3 The second shaft end reinforcing rib 32 is also designed to extend in a tapered configuration from the second end 12 of the body 1 towards the fourth end 22 of the attachment mechanism 2.

[0047] The plurality of reinforcing ribs / auxiliary ribs can further include a circumferential auxiliary rib assembly 4 and an axial auxiliary rib assembly 5 arranged between the first shaft end reinforcing rib 31 and the second shaft end reinforcing rib 32 in the axial direction of the valve body 100.

[0048] Continuing to refer to Figure 4 and Figure 5 wherein Figure 4 is a front view of the valve body 100, Figure 5 is a top view of the valve body 100. The circumferential auxiliary rib assembly 4 includes a first circumferential auxiliary rib 41, a second circumferential auxiliary rib 42 and a third circumferential auxiliary rib 43. The three circumferential auxiliary ribs are fixedly connected to the outer circumferential surfaces of the body 1 and the attachment mechanism 2 respectively, and preferably extend continuously around the entire circumference on the outer circumferential surfaces of the combination of the body 1 and the attachment mechanism 2.

[0049] The first circumferential auxiliary rib 41, the second circumferential auxiliary rib 42 and the third circumferential auxiliary rib 43 are arranged at intervals from each other along the axial direction of the valve body 100 between the first shaft end reinforcing rib 31 and the second shaft end reinforcing rib 32. Among them, one of the circumferential auxiliary ribs (herein the second circumferential auxiliary rib 42) can be arranged at a position having the smallest outer diameter on the outer circumferential surface of the body 1. With this design, the structurally weakest part of the valve body 100 can be further reinforced, thereby ensuring the structural strength of the entire valve body 100.

[0050] Further, although the circumferential auxiliary rib assembly 4 is exemplified herein as including three circumferential auxiliary ribs 41, 42, 43, it is understood by those skilled in the art that the circumferential auxiliary rib assembly 4 can include more or less circumferential auxiliary ribs. Herein, in order to ensure a good structural reinforcement effect, it is preferred that the circumferential auxiliary rib assembly 4 include at least three circumferential auxiliary ribs.

[0051] In particular, referring to Figure 5 , the axial auxiliary rib assembly 5 includes at least two axial auxiliary ribs. Each axial auxiliary rib extends along the axial direction of the valve body 100 and extends from the first axial end reinforcing rib 31 to the second axial end reinforcing rib 32. The axial auxiliary rib assembly 5 is capable of providing good support to the first axial end reinforcing rib 31 and the second axial end reinforcing rib 32. Further, the plurality of axial auxiliary ribs are designed to be spaced apart from each other along the circumference of the combination of the body 1 and the attachment mechanism 2.

[0052] It is noted here that, in order to clearly show, Figure 5 only the first axial auxiliary rib 51 arranged on the outer circumferential surface of the body 1 and the second axial auxiliary rib 52 arranged on the outer circumferential surface of the attachment mechanism 2 are indicated, but it is understood by those skilled in the art that, Figure 5 other ribs extending in parallel with the first axial auxiliary rib 51 and the second axial auxiliary rib 52 and spaced apart along the circumference of the combination of the body 1 and the attachment mechanism 2 are also axial auxiliary ribs.

[0053] Herein, at least one of the axial auxiliary ribs is arranged on the outer circumferential surface of the body 1, and at least one other of the axial auxiliary ribs is arranged on the outer circumferential surface of the attachment mechanism 2, thereby ensuring a structural reinforcement effect on both the body 1 and the attachment mechanism 2. It is understood by those skilled in the art here that, although providing one axial auxiliary rib for each of the body 1 and the attachment mechanism 2 can achieve the effect of axially reinforcing the body 1 and the attachment mechanism 2, it is preferred that, as Figure 5 indicated, more axial auxiliary ribs are provided for both the body 1 and the attachment mechanism 2 to achieve a better reinforcement effect.

[0054] For example, at least three axial auxiliary ribs can be provided on the outer circumferential surface of the body 1, and at least three axial auxiliary ribs can be provided on the outer surface of the attachment mechanism. The at least three axial auxiliary ribs arranged on the outer circumferential surface of the body 1 can be equiangularly spaced along the circumference of the body 1, and the at least three axial auxiliary ribs arranged on the outer circumferential surface of the attachment mechanism 2 can be equiangularly spaced along the outer circumferential surface of the attachment mechanism 2.

[0055] The shaft end reinforcing rib assembly 3, the circumferential auxiliary rib assembly 4 and the axial auxiliary rib assembly 5 described above can structurally reinforce the body 1 and the attachment mechanism 2, which ensures that the valve body 100 can withstand a large external pressure when in operation, and guarantees that the valve body 100 does not deform when connected to fixed components in, for example, an air conditioner.

[0056] It is emphasized here that in the case where the valve body 100 is made of engineering plastic and is formed in one piece by means of the injection molding process, the shaft end reinforcing rib assembly 3, the circumferential auxiliary rib assembly 4 and the axial auxiliary rib assembly 5 described above are also integrally formed with the body 1 and the attachment mechanism 2 by means of the injection molding process.

[0057] The preferred embodiments according to the present application are described above in conjunction with the specific embodiments. It can be understood that the above description is only exemplary and not restrictive, and those skilled in the art can think of various modifications and changes with reference to the above description without departing from the scope of the present application. These modifications and changes are also included in the protection scope of the present application.
