Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical connection technical field especially a valve capable of making the limiting structure more reliable. BACKGROUND

[0002] The pipeline is a device for conveying gas, liquid or fluid with solid particles, and a plurality of pipeline components can be connected in the pipeline, including but not limited to valves, pipes, pipeline connectors and the like. In a pipeline, it is often necessary to connect between valves, between pipes and valves, and between valves and pipeline connectors. The connection method and structure of the pipeline are various, and the conventional pipeline connection method mostly adopts a threaded connection structure. Although this method has high reliability, in order to ensure the sealing, it is necessary to wind a raw material belt during installation, which is low in installation efficiency.

[0003] In order to improve the installation efficiency, the prior art also proposes a pipeline connection method using a plug-in structure. Although this structure has high installation efficiency, it still has the following problems:

[0004] The existing structure usually adopts a single insertion hole matched with a single insertion pin, which can only limit one side of the pipeline, so that when the impact pressure exists in the connected pipeline, the position not limited by the insertion pin, especially the position opposite to the position limited by the insertion pin, has the risk of sealing point leakage or even pipeline rotation disconnection. INVENTION CONTENTS

[0005] The utility model provides a kind of plug-in structure, which aims to at least overcome part of the above-mentioned problems existing in the assembly process of prior art.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A valve includes a valve body and a first connector, wherein the valve body has a valve cavity inside for medium flow, the first connector is arranged on one side of the valve body and communicates with the valve cavity, the first connector has two insertion holes, and the two insertion holes are arranged symmetrically on both sides of the first connector.

[0008] As an optional technical solution, the insertion hole is formed as an arc-shaped hole along the circumference of the first connector. The arc-shaped insertion hole can be formed as a long slot, which facilitates the side surface of the insertion pin to be clamped into the limiting slot through the insertion hole. In particular, the matching section of the insertion pin and the insertion hole is a straight rod, so that the side surface of the insertion pin only needs to be clamped into the insertion hole without being inserted into the insertion pin. The side surface of the plug-in line corresponding to the insertion hole will be clamped into the limiting slot through the insertion hole.

[0009] As an optional technical solution, the first connector includes a main body and a boss, each boss is arranged on the two sides of the main body, and each insertion hole is arranged in the boss. The length of the insertion hole can be increased by arranging the boss, thereby improving the reliability of the plug-in structure composed of the plug and the insertion hole.

[0010] As an optional technical solution, the valve further includes a second connector arranged on the other side of the valve body and communicating with the valve cavity, and the second connector has two insertion holes arranged symmetrically on the two sides of the first connector. By arranging the second connector of the valve as a female connector, the valve can be installed when the connectors of the pipeline components at both ends are male connectors, without the need to add an adapter, and can be applied to more installation scenarios.

[0011] As an optional technical solution, the valve further includes a second connector arranged on the other side of the valve body and communicating with the valve cavity, and the second connector has two insertion holes arranged symmetrically on the two sides of the first connector. By arranging the second connector of the valve as a female connector, the valve can be installed when the connectors of the pipeline components at both ends are male connectors, without the need to add an adapter, and can be applied to more installation scenarios.

[0012] As an optional technical solution, the limiting groove is arranged around the entire circumference of the second connector. It is convenient to process and easy to disassemble and assemble.

[0013] As an optional technical solution, the limiting groove is formed on the two sides of the outer surface of the second connector and is symmetric along the axial plane of the second connector. The limiting groove of the second connector is arranged as two, and the positions of the two limiting grooves correspond to the positions of the insertion holes of the first connector, so that the second connector of the valve can be more suitable for the plug-in connector with double insertion holes.

[0014] As an optional technical solution, the bottom surface of the limiting groove is a plane. After the plug is inserted, the circumferential rotation of the second connector is limited, so that the second connector can be locked in the circumferential direction with the external pipeline connector through the plug-in structure.

[0015] As an optional technical solution, the valve further includes a second connector arranged on the other side of the valve body and communicating with the valve cavity, and the second connector is a threaded connector or a hot melt connector. Both threaded connectors and hot melt connectors are connectors of conventional pipeline components. By arranging the second connector of the valve as a threaded connector (including but not limited to external threads, internal threads, live threaded structures, etc.), the valve can be installed when the connector of one pipeline component is a male connector and the other end of the pipeline component is a conventional threaded connector. By arranging the second connector of the valve as a hot melt connector, the valve can be installed when the connector of one pipeline component is a male connector and the other end of the pipeline component is a conventional hot melt connector, without the need to add an adapter, and can be applied to more installation scenarios.

[0016] As an optional technical solution, the valve body can be any one of a gate valve, a ball valve, a check valve, a stop valve, and a pressure reducing valve.

[0017] The utility model discloses a beneficial effect:

[0018] According to the plug-in structure provided by the utility model, the first connector (plug-in structure female head) is arranged on one side of the valve, so that the valve can be matched and plugged with the second connector with the limiting groove through the plug-in structure, and quick installation is realized. Further, through the double jack design, the latch of the plug-in structure can be inserted into the limiting groove from the symmetrical two sides to limit the valve, so that when the impact pressure exists in the butt joint flow channel, reliable limiting can be carried out on the opposite sides of the connector, and the risk of sealing point leakage or even pipeline rotation disconnection is reduced.

[0036] First embodiment

[0037] Figure 1 It is a whole structure schematic diagram of a valve provided by the first embodiment of the utility model. Figure 2It is the first embodiment of the utility model provides the cross section structure schematic diagram of the plug -in structure of the first joint of valve and external pipeline joint.

[0038] It should be noted that, as Figure 2 The plug -in structure shown, one joint is limited in the way of inserting into another joint, in the description of the utility model, "male head", "male joint" all refer to the joint inserted into another joint, "female head", "female joint" refers to the joint set on one joint. In particular, the first joint 2 of the valve of the utility model is a female joint of plug -in structure, the second joint 3 (see Figure 4 ) can be male joint or female joint, which is not limited here.

[0039] In combination Figure 1 And Figure 2 In the embodiment, a valve is provided, which comprises a valve body 1 and a first joint 2. In the drawings, the valve body 1 is illustrated as a ball valve, but the utility model is not limited thereto, the valve body 1 can be the main joint of any type of valve, for example, it can be a gate valve, a ball valve, a check valve, a stop valve, a pressure reducing valve, etc., and the above technical solutions which simply replace the structure of the valve body 1 all belong to the protection scope of the utility model. The inside of the valve body 1 is formed into a hollow valve cavity 11 (see attached Figure 7 ), which can contain medium, and the medium can enter the valve cavity 11 through the inlet of the valve body 1 and then flow out through the outlet.

[0040] Generally speaking, the valve body 1 is connected with at least two joints, one water inlet joint and one water outlet joint, wherein the first joint 2 can be a water inlet joint or a water outlet joint, which is not limited here. The first joint 2 is arranged on one side of the valve body 1 and communicates with the valve cavity 11, so that the medium flowing into the first joint 2 (water inlet joint) can flow out through the valve cavity 11, or the medium in the valve cavity 11 can flow out through the first joint 2 (water outlet joint). In particular, in the embodiment, the first joint 2 has two insertion holes 4, which are arranged symmetrically on both sides of the first joint 2. That is, the two insertion holes 4 are arranged on the radial sides of the first joint 2 and symmetrically arranged with respect to the axial plane of the first joint 2.

[0041] Specifically, as Figure 2 The external pipeline joint 100 (male head) has a limiting groove 5, and the external pipeline joint 100 can be plugged into the first joint 2, and then limited and connected by the way that the pin 6 passes through the insertion hole 4 and is limited in the limiting groove 5. It should be noted that, Figure 1 And Figure 2The structure of the external pipe joint 100 and the plug 6 is exemplified in the embodiment, but it is not limited to that the valve of the utility model can only be installed in cooperation with the structure, and simple replacement of the shape of the insertion hole 4, the plug 6 and the limiting groove 5, as long as the plug 6 passes through the insertion hole 4 and is limited in the limiting groove 5, belongs to the protection scope of the utility model.

[0042] In the embodiment, the first joint 2 (female head of the plug-in structure) is arranged on one side of the valve, so that the valve can be matched and plugged with the external pipe joint 100 (male head) with the limiting groove 5 through the plug-in structure, and quick installation is realized. Further, through the design of the double insertion hole 4, when the valve is plugged and installed with the external pipe joint 100, the plug 6 can be inserted into the limiting groove 5 from the two symmetrical sides to limit the valve and the external pipe joint 100, so that when there is impact pressure in the connected flow channel, reliable limiting can be realized on the two opposite sides of the joint, and the risk of leakage of the sealing point or even rotation disconnection of the pipe is reduced.

[0043] It should be noted that, Figure 1 and Figure 2 A preferred structure of the insertion hole 4 is exemplified in the embodiment, the insertion hole 4 is formed as an arc-shaped hole along the circumference of the first joint 2, and the arc-shaped insertion hole 4 can be formed as a long strip-shaped through groove, so that the side surface of the plug 6 can be clamped into the limiting groove 5 through the insertion hole 4, especially for the straight rod-shaped single plug and the U-shaped plug (as shown in Figure 2 The matching section of the plug 6 and the insertion hole 4 is straight rod-shaped, so that the side surface of the plug 6 can be clamped into the insertion hole 4 without inserting the plug 6, and the side surface of the plug corresponding to the insertion hole 4 can pass through the insertion hole 4 and be clamped into the limiting groove 5 of the external pipe joint 100 for limiting.

[0044] Further, when the side surface of the plug 6 abuts against the two ends of the insertion hole 4, the side surface of the plug 6 passes through the insertion hole 4 and is clamped into the limiting groove 5 of the external pipe joint 100 for limiting, so that the plug 6 can be fixed relative to the first joint 2 of the valve in the circumferential direction and cannot rotate relative to the first joint 2, and the limiting effect is better. Preferably, the side surface of the plug 6 passing through the insertion hole 4 can be clamped into the limiting groove 5 of the external pipe joint 100 and abut against the bottom surface of the limiting groove 5, so as to further improve the limiting effect of the plug-in structure.

[0045] Figure 3 Another structure of the insertion hole 4 is also exemplified in the embodiment, as shown in Figure 3 The first joint 2 of the valve can include a main body part 21 and a boss 22, each boss 22 is arranged on the two sides of the main body part 21, and two insertion holes 4 are respectively arranged in the boss 22. The length of the insertion hole 4 can be increased through the arrangement of the boss 22, so as to improve the reliability of the plug-in structure composed of the plug 6 and the insertion hole 4.

[0048] As Figure 4 The valve further includes a second joint 3 arranged on the other side of the valve body 1 and communicated with the valve cavity 11, and the second joint 3 has two insertion holes 4, and the two insertion holes 4 are arranged on the two sides of the first joint 2 and symmetrically arranged. That is, the first joint 2 and the second joint 3 of the valve are both female joints of the plug-in structure, which are used for corresponding connection with the external pipeline joint 100 (male head). It should be noted that here only the two joint types of the valve are both female joints, and the valve is not limited to only two joints, and the structure of the two joints of the valve is not limited to be completely consistent. The first joint 2 and the second joint 3 can also be formed as female joints with different details or different sizes, which are all applicable to the embodiments of the utility model.

That is, the first joint 2 and the second joint 3 of the valve are both female joints of the plug-in structure, which are used for corresponding connection with the external pipeline joint 100 (male head). It should be noted that here only the two joint types of the valve are both female joints, and the valve is not limited to only two joints, and the structure of the two joints of the valve is not limited to be completely consistent.

[0055] In some other preferred embodiments, Figure 7 The third embodiment of the utility model provides an axial cross-sectional view of a valve and an external pipeline joint plug-in connection. As shown in the figure, Figure 7 The plug-in structure also includes a sealing ring 7, which can be sleeved on the outer surface of the second joint 3 of the valve, and is used to seal the passage formed by the abutment of the external pipeline joint 100 (female joint) and the second joint 3 of the valve.

[0056] The sealing ring 7 is arranged at least between the outer end of the second joint 3 and the limiting groove 5, wherein the outer end refers to the end of the second joint 3 towards the external pipeline joint 100 when the external pipeline joint 100 and the second joint 3 are assembled. When the second joint 3 is inserted into the external pipeline joint 100 for plug-in, the sealing ring 7 sleeved on the outer surface of the second joint 3 is extruded and deformed, so as to be compressed between the inner surface of the external pipeline joint 100 and the outer surface of the second joint 3, and the sealing ring 7 is closer to the outer end of the second joint 3, so as to achieve the sealing effect of the connection structure between the external pipeline joint 100 and the second joint 3, and prevent the medium in the passage from overflowing from the connection.
