Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a metering connection valve. Background Technology

[0002] A connecting valve is a device used to connect a piping system to valves, equipment, etc. Its main function is to ensure the safe and reliable transmission and control of fluids or gases within the piping system. Connecting valves come in various types and structures depending on the connection method and application scenario.

[0003] Patent CN 216519781 U discloses a stable snap-fit ​​one-way valve, including a first valve body assembly and a second valve body assembly, a first positioning ring installed on the outer side of the right end of the first valve body assembly, a second positioning ring installed on the outer side of the left end of the second valve body assembly, and a filter basket disposed on the inner side of the left end of the first valve body assembly for filtering impurities in water.

[0004] However, the device still has the following problems: although it can filter fluids, it does not have the ability to detect the temperature and pressure of the fluids, and it cannot adjust the flow range according to the actual application scenario, which limits the installation scenarios. Utility Model Content

[0005] To address the problems existing in the prior art, a metering connection valve is provided. This device has a clever structure and can be used as an auxiliary connection valve. The assembled PT valve can measure the temperature and pressure values ​​of the flow rate within the valve body in real time. The use of valve cores with different specifications allows for adjustment of the flow range, making it suitable for the needs of different installation locations.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a metering connection valve, including a valve body, in which valve cores with different sized orifices are assembled, and a stop part is provided in the valve body, with the valve cores located on the water-facing side of the stop part; the valve body is equipped with at least two PT valves, which are arranged on both sides of the valve cores.

[0007] Preferably, the valve core includes a horizontal surface in the middle and long and short inclined surfaces on both sides, with the long inclined surface fitting into the stop portion and the short inclined surface located on the water-facing side.

[0008] Preferably, the distance between the ends of the long inclined planes near the stop is less than the distance between the stops, and the distance between the horizontal planes is greater than the distance between the stops, so that the stop can slide along the surface of the long inclined plane.

[0009] Preferably, the PT valve has a detection port, which is located on both sides of the valve core and is connected to the valve body.

[0010] Preferably, the PT valve is provided with a sealing block having a detection hole, and the sealing block has an automatic tightening function to automatically seal the detection hole.

[0011] Preferably, the PT valve is threadedly connected to a valve cover, the valve cover is connected to a connecting ring, the PT valve has an annular groove, and the other end of the connecting ring is slidably sleeved in the annular groove.

[0012] Preferably, the valve body is slidably connected with a locking block, and the assembled valve core is located between the locking block and the stop portion.

[0013] Preferably, a magnet that attracts the card block is connected inside the valve body, and the magnetic force of the magnet can make the upper surface of the card block lower than or flush with the inner wall of the valve body.

[0014] Preferably, the valve body is slidably connected to a push rod, and a push plate is fixedly connected to one end of the push rod on the water-facing side. When the water flow impacts the push plate, the push rod can drive the locking block to move towards the center of the valve core.

[0015] Preferably, the card block has a first inclined surface and a horizontal groove that are interconnected, and the push rod has a second inclined surface. When the push rod moves to the end of the horizontal groove, the second inclined surface is located at the connection between the first inclined surface and the horizontal groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can be used as an auxiliary connection in HVAC and thermal air conditioning systems. The PT valve installed can measure the temperature and pressure values ​​of the flow rate in the valve body in real time. With valve cores of different specifications, the flow rate range can be adjusted, which is suitable for the needs of different installation sites and can be used as an auxiliary connection valve.

[0017] 2. This utility model is equipped with a stop part. With the impact of the water flow, the stop part can come into contact with the long inclined surface of the valve core. The greater the impact force, the tighter the contact, which can better fix the valve core and effectively improve the sealing effect at the valve core connection. The sealing block set in the PT valve can automatically seal the detection hole by utilizing its own property of automatically tightening, preventing liquid from flowing out of the PT valve when the valve cover is opened, thus improving the overall sealing effect.

[0018] 3. This utility model is equipped with a locking block. When water flows through, the water impacts the push plate, and the push plate drives the locking block to move towards the center of the valve body via the push rod, so that the locking block can move into the valve body to limit the valve core. When no water flows through, the magnet drives the locking block to automatically reset, so as not to affect the normal replacement of the valve core. This ensures that the valve body always locks the valve core during use, and the valve core can be easily replaced when not in use. Attached Figure Description

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1 like Figures 1-4 As shown, this embodiment proposes a metering connection valve, including a valve body 1, a valve core 5 with a central hole of different sizes assembled inside the valve body 1, a stop part 19 provided inside the valve body 1, and the valve core 5 located on the water-facing side of the stop part 19. The stop part 19 realizes the limiting work of the valve core 5, so that the valve core 5 can be fixed in a suitable position inside the valve body 1.

[0023] One end of the valve body 1 is the water inlet end, and the water inlet end is provided with an internal thread 2. The other end of the valve body 2 is the water outlet end, and the water outlet end is provided with an external thread 3.

[0024] The valve core 5 includes a horizontal surface 51 in the middle and a long inclined surface 52 and a short inclined surface 53 on both sides. The long inclined surface 52 fits into the stop part 19, and the short inclined surface 53 is located on the water-facing side. The length of the long inclined surface 52 is longer than that of the short inclined surface 53. The setting of the short inclined surface 53 facilitates the processing of the valve core 5 and allows the water flow to better impact the short inclined surface 53, so that the long inclined surface 52 fits into the stop part 19 better.

[0025] The distance between the ends of the long inclined planes 52 near the stop portions 19 is less than the distance between the stop portions 19, and the distance between the horizontal planes 51 is greater than the distance between the stop portions 19. This allows the stop portions 19 to slide along the surface of the long inclined planes 52, and the stop portions 19 can only slide along the long inclined planes 52, and will not slide to the position of the horizontal planes 51, thus facilitating the installation and fixing of the valve core 5.

[0026] As the water flow impacts the valve core 5, the stop part 19 comes into contact with the long inclined surface 52 of the valve core 5. The greater the impact force, the tighter the contact, which can better fix the valve core 5 and effectively improve the sealing effect at the connection between the valve core 5 and the valve body 1. The central hole size of the valve core 5 is highly precise and varies, so different sizes of valve core 5 can be selected according to the flow range of the installation site.

[0027] The valve body 1 is equipped with at least two PT valves 4, which are arranged on both sides of the valve core 5. In this embodiment, there are two PT valves 4. The two PT valves 4 are not coplanar and are perpendicular to each other, thereby realizing the measurement of water flow at different positions in the valve body 1 and further improving the measurement accuracy.

[0028] The PT valve 4 has a detection port 6, which is located on both sides of the valve core 5 and is connected to the valve body 1. The PT valve 4 is equipped with a sealing block 10 with a detection hole 11. The sealing block 10 has an automatic tightening function, which automatically seals the detection hole 11.

[0029] The sealing block 10 is made of rubber. The main component of the rubber stopper is rubber, which is a polymer material with high elasticity. Temperature and pressure probes can be inserted into the detection hole 11. The temperature and pressure probes can enter the valve body 1 through the detection port 6. As the outer wall of the temperature and pressure probes applies pressure to the rubber stopper, the rubber stopper will undergo elastic deformation. This deformation makes the outer surface of the rubber stopper fit tightly with the outer surface of the temperature and pressure probes, thereby forming a seal.

[0030] Once the temperature and pressure probes are removed from the detection hole 11, the rubber stopper will return to its original shape due to its elasticity. The rubber stopper will automatically tighten, thus achieving a seal and completely sealing the detection hole 11 to prevent water from flowing through.

[0031] The PT valve 4 is threadedly connected to a valve cover 7, and the valve cover 7 is connected to a connecting ring 8. The PT valve 4 has an annular groove 9, and the other end of the connecting ring 8 is slidably fitted in the annular groove 9. The connecting ring 8 can rotate freely in the annular groove 9, so as not to affect the valve cover 7 being screwed in and out. At the same time, the connecting ring 8 connects to the valve cover 7, and the setting of the connecting ring 8 can effectively prevent the valve cover 7 from being lost.

[0032] The valve body 1 can be used as an auxiliary connection in HVAC and thermal air conditioning systems. The installed PT valve 4 can measure the temperature and pressure values ​​of the flow rate inside the valve body 1 in real time. The valve cores 5 with different specifications can adjust the flow range, which is suitable for the needs of different installation sites and can be used as an auxiliary connection valve.

[0033] Example 2 Reference Appendix Figures 4-6 The other structures are the same as in Embodiment 1, except that the limiting of the valve core is taken into account in this embodiment.

[0034] The valve body 1 is slidably connected with a locking block 12. The assembled valve core 5 is located between the locking block 12 and the stop part 19. The locking block 12 can be set in several ways according to actual needs. In this embodiment, there are two locking rods 12, and the two locking blocks 12 are symmetrically arranged along the center position of the valve core 5.

[0035] A magnet 15 is connected inside the valve body 1, which attracts the locking block 12. The part of the locking block 12 near the magnet 15 can be an iron block. The magnet 15 attracts the locking block 12, so that the locking block 12 can move away from the center of the valve body 1. The magnetic force of the magnet 15 can make the upper surface of the locking block 12 lower than or flush with the inner wall of the valve body 1, thereby facilitating the disassembly of the valve core 5.

[0036] The valve body 1 is slidably connected to a push rod 13. The push rod 13 is fixedly connected to a push plate 14 at one end on the water-facing side. The push plate 14 is set parallel to the valve core 5. When the water flow impacts the push plate 14, the push rod 13 can drive the locking block 12 to move towards the center of the valve core 1.

[0037] The locking block 12 has a first inclined surface 16 and a horizontal groove 18 that are interconnected. The push rod 13 has a second inclined surface 17. When the push rod 13 moves toward the locking block 12, it can drive the locking block 12 toward the center of the valve body 1 through the second inclined surface 17. When the push rod 13 moves to the end of the horizontal groove 18, the second inclined surface 17 is located at the connection between the first inclined surface 16 and the horizontal groove 18.

[0038] The magnetic force of magnet 15 is suitable and less than the impact force of water flow on push plate 14. Therefore, when water flow drives block 12 to move through push plate 14, it overcomes the magnetic force of magnet 15. When push rod 13 slides into horizontal groove 18, push plate 14 contacts inner wall of valve body 1. Therefore, push plate 14 cannot continue to slide inward, thereby improving the sealing of push rod 13 and valve body 1.

[0039] When water flows through, it impacts the push plate 14. The push plate 14, through the push rod 13, drives the locking block 12 to move towards the center of the valve body 1, allowing the locking block 12 to move into the valve body 1 and limit the valve core 5. When no water flows through, the magnet 15 drives the locking block 12 to automatically reset, thus not affecting the normal replacement of the valve core 5. This ensures that the valve body 1 always locks the valve core 5 during use, while the valve core 5 can be easily replaced when not in use.

[0040] The specific working process is as follows: According to the actual usage requirements, select the valve core 5 with the corresponding hole size. The valve core 5 is pushed in from the water inlet end of the valve body 1, and finally the valve core 5 comes into contact with the stop part 19. When the valve body 1 is connected to the corresponding pipeline, when water flows through, the water flow impacts the valve core 5, causing the long inclined surface 52 of the valve core 5 to come into further contact with the stop part 19, thereby improving the sealing performance at the connection between the valve core 5 and the valve body 1.

[0041] At the same time, the water flow impacts the push plate 14, and the push plate 14 drives the locking block 12 to move towards the center of the valve body 1 through the push rod 13, so that the locking block 12 can move into the valve body 1 to limit the valve core 5. When it is necessary to monitor the valve body 1, the temperature and pressure probes are inserted into the detection port 6 through the detection hole 11 by unscrewing the valve cover 7, and then inserted into the valve body 1 to monitor the flow rate, temperature and pressure before and after the valve core 5.

[0042] When the valve core 5 needs to be disassembled, the valve body 1 is disassembled. When there is no water flow, the magnet 15 drives the locking block 12 to automatically reset, so as not to affect the normal replacement of the valve core 5. This ensures that the valve body 1 always locks the valve core 5 during use, and the valve core 5 can be easily replaced when not in use.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
