Description

Technical Field

[0001] This utility model relates to the field of flow meter valve technology, and in particular to a one-way flow meter valve. Background Technology

[0002] A flow meter valve is a device used to control and monitor fluid flow. It is typically used in fluid transport systems where fluid flow control is required. It ensures that the fluid flow in the pipeline remains within a set range by adjusting the set flow rate, and features high accuracy and wide applicability.

[0003] Existing technologies often have the following drawbacks: when installing a one-way flow meter valve, operators usually need to manually control the connection pipe and the one-way flow meter valve to position them in order to facilitate the connection between the two, which makes it difficult to install the one-way flow meter valve alone.

[0004] Therefore, this utility model provides a one-way flow meter valve. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the installation of a one-way flow meter valve typically requires manual control of the connecting pipe and the one-way flow meter valve by the operator to facilitate the connection between the two, making the installation of the one-way flow meter valve alone difficult. Therefore, this invention proposes a one-way flow meter valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a one-way flow meter valve, comprising a valve body and an adjusting valve cap, wherein a flow cup is installed inside the valve body, a flow direction indicator groove is provided on the surface of the valve body, and a positioning device is provided on the surface of the valve body, the positioning device comprising two fixing blocks, both fixing blocks being fixedly connected to the surface of the valve body, and a "U"-shaped plate being slidably connected to the inner wall of both fixing blocks, a first arc plate being fixedly connected to the side of the "U"-shaped plate away from the fixing blocks, and a second arc plate being installed on the side of the first arc plate away from the "U"-shaped plate.

[0007] The effect achieved by the above components is that when the valve body needs to be installed, the first arc plate and the second arc plate can be connected to the valve body using the "U" shaped plate, thereby clamping the connecting pipe through the first arc plate and the second arc plate to achieve the positioning effect.

[0008] Preferably, an adjusting screw is threaded into the inner wall of the second arc plate, the adjusting screw is rotatably connected to the first arc plate, and a limiting rod is fixedly connected to the side of the first arc plate near the second arc plate, the limiting rod being slidably connected to the inner wall of the second arc plate.

[0009] The effect achieved by the above components is that when it is necessary to adjust the distance between the first arc plate and the second arc plate, the second arc plate can be moved closer to the first arc plate by rotating the adjusting screw, thus completing the distance adjustment.

[0010] Preferably, the inner wall of the fixing block is slidably connected to a plug rod, and the plug rod is slidably connected to the inner wall of the "U"-shaped plate.

[0011] The effect achieved by the above components is that the insert rod that is slidably connected to the inner wall of the fixed block can move, thereby controlling the connection and separation of the fixed block and the "U"-shaped plate.

[0012] Preferably, the end of the insertion rod away from the "U"-shaped plate is fixedly connected to a mounting plate, and a spring is sleeved on the surface of the insertion rod, with the two ends of the spring being fixedly connected to the mounting plate and the fixing block, respectively.

[0013] The effect achieved by the above components is that the spring can be installed through the mounting plate, thereby ensuring the stability of the connection between the plug rod and the fixing block, and at the same time achieving the effect of limiting the position of the plug rod.

[0014] Preferably, the surface of the valve body is provided with a protective device, which includes six rectangular plates. All six rectangular plates are fixedly connected to the surface of the valve body, and a protective rotating plate is rotatably connected to the surface of each of the six rectangular plates.

[0015] The effect achieved by the above components is that the protective rotating plate and the valve body can be connected through the rectangular plate, so that the protective rotating plate can play a protective role.

[0016] Preferably, a limiting plate is fixedly connected to the upper surface of each of the six rectangular plates, and the limiting plate abuts against the protective rotating plate.

[0017] The effect achieved by the above components is that the rotation angle of the protective rotating plate can be limited by the setting limit plate, thereby ensuring the protective effect of the protective rotating plate.

[0018] Preferably, a support plate is fixedly connected to the side of the protective rotating plate away from the flow cup, a retaining ring is installed on the upper surface of the support plate, and a fixing screw is threaded into the inner wall of the protective rotating plate, the external thread of the fixing screw matching the internal thread of the retaining ring.

[0019] The above components achieve the following effects: the mounting plate can position the retaining ring during installation, and the fixing screw can connect the retaining ring and the protective rotating plate.

[0020] In summary:

[0021] 1. In this utility model, the positioning device can be used to position and restrict the position between the one-way flow meter valve and the connecting pipe by using the first arc plate and the second arc plate during the installation of the one-way flow meter valve, thereby facilitating the installation operation, improving the accuracy of connecting the one-way flow meter valve, and minimizing the adjustment work during the installation of the one-way flow meter valve.

[0022] 2. In this utility model, the protective device can protect the flow cup by using the protective rotating plate during the use of the one-way flow meter valve, thereby minimizing the risk of damage to the flow cup due to accidental bumps. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a one-way flow meter valve, including a valve body 1 and a regulating valve cap 2, a flow cup 3 installed inside the valve body 1, a flow direction indicator groove 4 provided on the surface of the valve body 1, a positioning device 5 provided on the surface of the valve body 1, and a protective device 6 provided on the surface of the valve body 1.

[0029] The specific configuration and function of its positioning device 5 and protective device 6 will be explained in detail below.

[0030] Reference Figure 1 and Figure 2 as well as Figure 3As shown in this embodiment: the positioning device 5 includes two fixing blocks 56, both of which are fixedly connected to the surface of the valve body 1. A U-shaped plate 51 is slidably connected to the inner wall of each fixing block 56. A first arc plate 52 is fixedly connected to the side of the U-shaped plate 51 away from the fixing blocks 56, and a second arc plate 53 is installed on the side of the first arc plate 52 away from the U-shaped plate 51. When the valve body 1 needs to be installed, the first arc plate 52 and the second arc plate 53 can be connected to the valve body 1 using the U-shaped plate 51, thereby clamping the connecting pipe through the first arc plate 52 and the second arc plate 53 to achieve a positioning effect. An adjusting screw 54 is threaded into the inner wall of the second arc plate 53, and the adjusting screw 54 is rotatably connected to the first arc plate 52. A limiting rod 55 is fixedly connected to the side of the first arc plate 52 near the second arc plate 53, and the limiting rod 55 is slidably connected to the inner wall of the second arc plate 53. When it is necessary to adjust the distance between the first arc plate 52 and the second arc plate 53, the second arc plate 53 can be moved closer to the first arc plate 52 by rotating the adjusting screw 54, thus completing the distance adjustment.

[0031] A rod 57 is slidably connected to the inner wall of the fixing block 56, and the rod 57 is slidably connected to the inner wall of the "U"-shaped plate 51. The rod 57, slidably connected to the inner wall of the fixing block 56, can move, thereby controlling the connection and separation of the fixing block 56 and the "U"-shaped plate 51. A mounting plate 58 is fixedly connected to the end of the rod 57 away from the "U"-shaped plate 51, and a spring 59 is sleeved on the surface of the rod 57. The two ends of the spring 59 are fixedly connected to the mounting plate 58 and the fixing block 56, respectively. The mounting plate 58 can be used to install the spring 59, thereby ensuring the stability of the connection between the rod 57 and the fixing block 56, and at the same time achieving the effect of limiting the position of the rod 57.

[0032] Reference Figure 1 and Figure 4 As shown, specifically, the protective device 6 includes six rectangular plates 61, all of which are fixedly connected to the surface of the valve body 1. A protective rotating plate 62 is rotatably connected to the surface of each of the six rectangular plates 61. The rectangular plates 61 connect the protective rotating plate 62 to the valve body 1, thus enabling the protective rotating plate 62 to provide protection. A limiting plate 63 is fixedly connected to the upper surface of each of the six rectangular plates 61, and the limiting plate 63 abuts against the protective rotating plate 62. The limiting plate 63 restricts the rotation angle of the protective rotating plate 62, thereby ensuring its protective effect.

[0033] Each side of the protective rotating plate 62 away from the flow cup 3 is fixedly connected to a support plate 64. A retaining ring 65 is installed on the upper surface of the support plate 64. A fixing screw 66 is threaded into the inner wall of the protective rotating plate 62, and the external thread of the fixing screw 66 matches the internal thread of the retaining ring 65. The support plate 64 can be used to position the retaining ring 65, and the fixing screw 66 can be used to connect the retaining ring 65 and the protective rotating plate 62.

[0034] Working principle: When installing valve body 1, firstly, move mounting plate 58 so that insert rod 57 slides on the inner wall of fixing block 56, thereby moving mounting plate 58 away from fixing block 56. Then, move "U" shaped plate 51 closer to fixing block 56, release mounting plate 58, and under the action of spring 59, insert rod 57 connects fixing block 56 and "U" shaped plate 51. Then, move valve body 1 closer to connecting pipe, rotate adjusting screw 54, and under the restriction of limit rod 55, first arc plate 52 and second arc plate 53 approach connecting pipe, clamping connecting pipe, thereby achieving the positioning effect of valve body 1. Then connect connecting pipe and valve body 1 to complete the installation of one-way flow meter valve. According to flow direction indicator groove 4, the correct installation of one-way flow meter valve can be guaranteed. By using the positioning device 5, the position between the one-way flow meter valve and the connecting pipe can be positioned and restricted by the first arc plate 52 and the second arc plate 53 during the installation of the one-way flow meter valve, which facilitates the installation operation, improves the accuracy of connecting the one-way flow meter valve, and minimizes the adjustment work during the installation of the one-way flow meter valve.

[0035] After installing the valve body 1 and adjusting the flow rate using the regulating valve cap 2, rotate the protective rotating plate 62 so that it rotates on the surface of the rectangular plate 61, causing the protective rotating plate 62 to rotate closer to the limiting plate 63. Then, move the retaining ring 65 closer to the support plate 64, so that the retaining ring 65 restricts the rotation of the protective rotating plate 62. Finally, use the fixing screw 66 to connect the retaining ring 65 and the protective rotating plate 62. Through the protective device 6, the protective rotating plate 62 can protect the flow cup 3 during the use of the one-way flow meter valve, thereby minimizing the possibility of damage to the flow cup 3 due to accidental impacts.
