Abstract
Description
Technical Field
[0001] This utility model relates to the field of water meter pressure balancing technology, and in particular to a water meter pressure balancer. Background Technology
[0002] A water meter pressure balancer is a device used to stabilize and regulate water pressure in a water supply system. Its core function is to solve a series of problems caused by water pressure fluctuations, ensuring the normal operation of water-using equipment and the accuracy of water meter readings.
[0003] However, existing water meter pressure balancers often suffer from unreasonable structural design and low adjustment accuracy. Some devices employ simple mechanical structures, making it difficult to respond quickly to drastic changes in water pressure. When the water pressure in the water supply network suddenly rises or falls, they cannot adjust effectively and in a timely manner, leading to significant errors in water meter readings. Some pressure balancers rely on external power sources for pressure regulation, which not only increases equipment costs and energy consumption but also carries the risk of malfunction due to power system failure. Furthermore, the connection stability between internal components of existing balancers is poor, making them prone to loosening and wear under long-term water flow impact, resulting in a short service life. Frequent maintenance and component replacement also increase operating costs and manpower burden. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of inaccurate water meter measurement caused by water pressure fluctuations, slow adjustment response of pressure balancers, poor structural stability and easy wear in the existing technology, and high energy consumption and maintenance costs due to reliance on external power. Therefore, a water meter pressure balancer is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water meter pressure balancer, comprising a valve body, a water meter body fixedly mounted on the top of the valve body, a pressure balancing mechanism fixedly mounted on the inner wall of the valve body, the pressure balancing mechanism comprising a positioning rod, a baffle plate and a transmission rod, support rods fixedly mounted at equal intervals at one end edge of the positioning rod, the support rods being fixedly connected to the inner wall of the valve body, the transmission rod being rotatably mounted inside the positioning rod, a collar threadedly connected to the outer wall of the transmission rod, a push rod rotatably connected between the collar and the baffle plate, and an electric impeller fixedly connected to the bottom of the water meter body, the electric impeller being fixedly connected to the transmission rod.
[0006] Preferably, positioning blocks are fixedly installed at equal intervals on the outer wall of the positioning rod, and the positioning blocks are arranged alternately with the support rod.
[0007] Preferably, one end of the blocking plate is rotatably connected to the support rod, and the blocking plate is attached to the surface of the positioning rod.

[0009] Preferably, protrusions are fixedly installed at equal intervals along the edge of the collar, and the collar is rotatably mounted on both ends of the protrusions.
[0010] Preferably, a docking block is fixedly installed on the inner side of the baffle plate, and the docking block is rotatably connected to the collar.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, through the mutual cooperation of the positioning rod, support rod, transmission rod, collar, push rod and baffle plate in the pressure balancing mechanism, the collar will move along its axial direction when the transmission rod rotates.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0017] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a water meter pressure balancer, including a valve body 1. A water meter body 2 is fixedly installed on the top of the valve body 1. A pressure balancing mechanism 3 is fixedly installed on the inner wall of the valve body 1. The pressure balancing mechanism 3 includes a positioning rod 31, a baffle plate 32, and a transmission rod 34. Support rods 33 are fixedly installed at equal intervals at one end of the positioning rod 31. The support rods 33 are fixedly connected to the inner wall of the valve body 1. The transmission rod 34 is rotatably installed inside the positioning rod 31. A collar 37 is threadedly connected to the outer wall of the transmission rod 34. A push rod 39 is rotatably connected between the collar 37 and the baffle plate 32. An electric impeller 4 is fixedly connected to the bottom of the water meter body 2. The electric impeller 4 is fixedly connected to the transmission rod 34.
[0018] The specific settings and functions of this embodiment are described below. When water flows through the valve body 1, the electric impeller 4 rotates under the action of the water flow. Since the electric impeller 4 is fixedly connected to the transmission rod 34, the transmission rod 34 rotates accordingly. Because the outer wall of the transmission rod 34 is threadedly connected to the collar 37, the collar 37 will move along its axial direction when the transmission rod 34 rotates. The collar 37 is rotatably connected to the baffle plate 32 through the push rod 39, thereby driving the baffle plate 32 to move. The positioning rod 31 is fixed to the inner wall of the valve body 1 through the support rod 33, which can play a positioning role for the transmission rod 34. The movement of the baffle plate 32 can adjust the cross-sectional area of the water flow channel. Pressure balance is achieved through the cooperation of positioning rod 31, support rod 33, transmission rod 34, collar 37, push rod 39, and baffle plate 32 in pressure balancing mechanism 3. Electric impeller 4 drives transmission rod 34 to move baffle plate 32 to balance pressure. The threaded connection between transmission rod 34 and collar 37, and the rotational connection between collar 37 and push rod 39 and baffle plate 32, make the movement and adjustment of baffle plate 32 more flexible and precise. It can effectively cope with different water flow pressure conditions and ensure the stability and accuracy of water meter body 2 measurement. At the same time, the support rod 33 is fixed to valve body 1, which enhances the stability of the overall structure and extends the service life of the equipment.
[0019] Example 2: Figure 2 , Figure 3 and Figure 4As shown, positioning blocks 35 are fixedly installed at equal intervals on the outer wall of positioning rod 31. Positioning blocks 35 and support rod 33 are arranged alternately. One end of blocking plate 32 is rotatably connected to support rod 33. Blocking plate 32 is attached to the surface of positioning rod 31. A cavity 36 is opened inside positioning rod 31. Push rod 39 is located inside cavity 36. Protrusions 38 are fixedly installed at equal intervals on the edge of collar 37. Collar 37 is rotatably installed at both ends of protrusions 38. A mating block 310 is fixedly installed on the inner side of blocking plate 32. The mating block 310 is rotatably connected to collar 37.
[0020] The overall effect of this embodiment is that the electric impeller 4 drives the transmission rod 34, and the collar 37 moves axially under the action of the thread on the transmission rod 34. The protrusion 38 on the edge of the collar 37 is rotatably connected to the collar 37. It drives the baffle plate 32 to swing around the rotational connection point with the support rod 33 through the push rod 39 in the cavity 36 of the positioning rod 31. At the same time, the baffle plate 32 is attached to the surface of the positioning rod 31. With the rotational connection between the docking block 310 and the collar 37, the size of the water flow channel is adjusted to achieve pressure balance. The positioning block 35 on the positioning rod 31 and the support rod 33 The staggered arrangement helps stabilize the structure. Through the cooperation of components such as positioning rod 31, positioning block 35, and support rod 33, the pressure balancing mechanism 3 is structurally stable. The staggered arrangement enhances the overall rigidity. The rotating connection between the baffle plate 32 and each component, as well as the design of fitting the positioning rod 31, allows the baffle plate 32 to swing and adjust flexibly and precisely, enabling it to respond quickly to changes in water pressure. The cooperation of the collar 37, protrusion 38, push rod 39, etc., ensures stable power transmission, effectively balances water pressure, improves the measurement accuracy and reliability of the water meter body 2, and extends the service life of the equipment.
[0021] The operating method and working principle of this device are as follows: When water flows through the valve body 1 normally, the water meter body 2 can control the electric impeller 4 to rotate. The electric impeller 4 is fixedly connected to the transmission rod 34, which drives the transmission rod 34 to rotate accordingly. Because the outer wall of the transmission rod 34 is threadedly connected to the collar 37, the collar 37 moves along its axial direction when the transmission rod 34 rotates. The protrusion 38 on the edge of the collar 37 is rotatably connected to it. The collar 37 is rotatably connected to the mating block 310 on the inner side of the baffle plate 32 through the push rod 39 located in the cavity 36 of the positioning rod 31, thereby driving the baffle plate 32 to swing around the rotation connection point with the support rod 33. The positioning rod 31 is fixed to the inner wall of the valve body 1 through the support rod 33, which plays a positioning role for the transmission rod 34. The positioning block 35 on the outer wall of the positioning rod 31 is staggered with the support rod 33 to help stabilize the structure. The swing of the baffle plate 32 adjusts the cross-sectional area of the water flow channel to achieve pressure balance and ensure the stability and accuracy of the measurement of the water meter body 2.
