Its function is to receive the control signal sent by the controller and change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. It is used to monitor water flow and facilitate the recording of water flow, so it is widely used in water pipelines.

[0003] Comparative document CN212275008U discloses a sealing structure for a water meter housing. "The sealing structure includes: a first sealing groove and silicone injected into the first sealing groove. The first sealing groove is arranged on a cover plate and is arranged near the edge of the cover plate. A cover shell can be detachably connected to the cover plate. A water meter actuator is arranged in a receiving cavity surrounded by the cover plate and the cover shell. The present application adopts the method of injection molding silicone to achieve physical sealing of the water meter housing. No filling equipment is required, no odor, no static curing operation is required, the work efficiency is improved, and the process of mass production is accelerated." However, the sealing structure in the patent is There are still certain disadvantages when using it. During the use of the existing water meter actuator, the outer shell and the water meter actuator are sealed by injection molding silicone. However, when taking a shower, hot water and cold water will get on the water meter actuator and the outer shell, causing the silicone to be affected by the alternating hot and cold factors. When the silicone is heated and cooled, the bond energy in its molecules will increase or decrease, causing the silicone to soften when heated and harden when cooled, resulting in poor sealing between the outer shell and the water meter actuator. At the same time, when the outer shell of the water meter actuator gets wet, scale will form on the observation lens of the outer shell, causing the lens to become blurred, making it inconvenient to see the displayed measurement values ​​on the water meter actuator.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0027] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0028] like Figure 1-Figure 9 As shown, a valve-controlled water meter actuator sealing device includes: a housing 1, a water meter actuator 101, a water inlet pipe 102, a water outlet pipe 103, a sealing component and a protective component, the water meter actuator 101 is arranged at the outer end of the housing 1, the water inlet pipe 102 is arranged at the top of the water meter actuator 101, the water outlet pipe 103 is arranged at the bottom of the water meter actuator 101, a sealing component is arranged between the housing 1 and the water meter actuator 101, and is used to seal the housing 1 and the water meter actuator 101, and a protective component is arranged outside the housing 1, and is used to prevent scale accumulation on the lens of the housing 1.

[0029] Among them, reference Figure 2-Figure 9 The sealing assembly includes: a pressure block a104 arranged on both sides of the outer end of the shell 1, a pressure block b105 is arranged on both sides of the outer end of the water meter actuator 101, a sealing block 106 is arranged on the inner side of the pressure block a104, and a limiting groove a107 is opened inside the pressure block b105 and used in conjunction with the sealing block 106, and the sealing block 106 is engaged and connected with the limiting groove a107.

[0030] When the water meter actuator 101 is in use, the outer shell 1 is covered on the water meter actuator 101 for installation, so that the water inlet pipe 102, the water meter actuator 101 and the water outlet pipe 103 are connected, and then the pressure blocks a104 on both sides of the outer end of the outer shell 1 are aligned with the pressure blocks b105 on both sides of the outer end of the water meter actuator 101 and pressed together. At this time, the sealing block 106 on the inner side of the pressure block a104 is inserted into the limiting groove a107, so that the sealing block 106 is snap-connected with the limiting groove a107, which is convenient for installing the outer shell 1 on the water meter actuator 101 for fixing, and can also increase the sealing between the outer shell 1 and the water meter actuator 101, which has a good waterproof effect, prevents water outside the shell from entering the water meter actuator 101, and prevents the components inside the water meter actuator 101 from being damaged by water, thereby solving the problem of poor sealing effect of injection molded silicone.

[0031] Moreover, the pressing block a104 and the pressing block b105 hide and protect the sealing block 106 over a large area, thereby preventing the sealing block 106 from being exposed, slowing down the aging time of the sealing block 106, extending the service life of the sealing block 106, and improving the sealing between the housing 1 and the water meter actuator 101. After the sealing block 106 is aged, the housing 1 can be quickly opened to replace the sealing block 106.

[0032] Among them, reference Figure 3 , Figure 4 and Figure 8 A clamping block 108 is provided on the inner top of the housing 1 , and a limiting groove b109 for use with the clamping block 108 is provided on the top of the water meter actuator 101 .

[0033] When the outer shell 1 is covered on the water meter actuator 101, the block 108 on the inner top of the outer shell 1 will be inserted into the limiting groove b109, so that the outer shell 1 and the top of the water meter actuator 101 fit together, and after the block 108 is inserted into the limiting groove b109, the outer shell 1 and the top of the water meter actuator 101 can be sealed.

[0034] Among them, reference Figure 3-Figure 8 Two recessed holes 110 are provided on the outside of the pressing block a104, screw holes 111 are provided inside the two recessed holes 110, a through hole 112 is provided on the sealing block 106 at a position relative to the screw holes 111, and a docking screw hole 113 is provided inside the limiting groove a107 at a position relative to the through hole 112.

[0035] After the sealing block 106 is inserted into the limiting groove a107, the pressing block a104 and the pressing block b105 fit together. At this time, the screw hole 111 on the pressing block a104, the through hole 112 on the sealing block 106 and the docking screw hole 113 in the limiting groove a107 are aligned with each other. The screw is screwed into the screw hole 111, and the screw passes through the through hole 112 and enters the docking screw hole 113. The screw can be tightened forcefully to increase the stability between the pressing block a104 and the pressing block b105 and prevent the shell 1 from falling.

[0036] Among them, reference Figure 2 and Figure 6 A sealing rubber head 3 is disposed at the bottom of the two concave holes 110 , a traction belt 301 is disposed at the top of the sealing rubber head 3 , and the traction belt 301 is made of plastic material, and a ring 302 is disposed at one end of the traction belt 301 .

[0037] After the screw is tightened in the screw hole 111, the screw is hidden inside the recessed hole 110. At this time, the sealing rubber head 3 is inserted into the recessed hole 110 to seal the recessed hole 110, provide waterproof protection for the screw, prevent the screw from rusting easily after contacting water, and avoid the screw from rusting inside the screw hole 111 and being inconvenient to disassemble.

[0038] Among them, reference Figure 2 and Figure 6 The bottom of the two recessed holes 110 are both provided with fixing rods 4 matched with the collars 302 , and the collars 302 are sleeved with the fixing rods 4 .

[0039] During the use of the sealing rubber head 3, a traction belt 301 and a ring 302 are installed on the top of the sealing rubber head 3. Since a fixing rod 4 is provided at the bottom of the recessed hole 110, the ring 302 is tightly placed on the fixing rod 4, so that the traction belt 301 and the sealing rubber head 3 on the ring 302 can be suspended in the air. When the sealing rubber head 3 is pulled out from the recessed hole 110, the sealing rubber head 3 is prevented from being lost. The traction belt 301 is made of plastic material, so that the traction belt 301 has good toughness, which makes it easy for the traction belt 301 to bend and insert the sealing rubber head 3 into the recessed hole 110. Example 2

[0040] Based on Example 1, Figure 1-Figure 2 The protection component includes: a protection cover 2 arranged outside the shell 1, an observation window 201 is provided on the protection cover 2, and the observation window 201 is made of a transparent plastic plate, a rotating shaft 202 arranged between the shell 1 and the protection cover 2, and a rotating ring 203 rotatably connected between the protection cover 2 and the rotating shaft 202.

[0041] During the use of the shell 1, a lens is provided on the shell 1 for viewing the metering value on the water meter actuator. Since a large amount of heat will reach the shell 1 during bathing, and after the shell 1 gets hot water, scale will form on the surface of the lens of the shell 1 over time. The protective cover 2 is flipped downward, and the protective cover 2 and the shell 1 can rotate through the rotating shaft 202 and the rotating ring 203, that is, the protective cover 2 is covered on the outside of the shell 1 to block water stains. The metering value in the lens can also be seen through the observation window 201, so as to prevent scale from forming on the surface of the lens of the shell 1 and avoid blurring of the lens and unclear viewing of the displayed metering value on the water meter actuator 101.

[0042] The device uses a sealing component to facilitate the installation of the housing 1 on the water meter actuator 101 for fixation, and can also increase the sealing between the housing 1 and the water meter actuator 101, thereby achieving a good waterproof effect, preventing water outside the housing from entering the water meter actuator 101, preventing the components inside the water meter actuator 101 from being damaged by water, and solving the problem of poor sealing effect of injection-molded silicone. The protective cover 2 can be covered on the outside of the housing 1 through the protective component to block water stains, prevent scale from forming on the lens surface of the housing 1, and prevent the lens from being blurred and the displayed measurement value on the water meter actuator from being unclear. Specific implementation method: When the water meter actuator 101 is in use, the water meter actuator 101 is installed on the outer shell 1, so that the water inlet pipe 102, the water meter actuator 101 and the water outlet pipe 103 are connected, and then the pressure blocks a104 on both sides of the outer end of the outer shell 1 are aligned with the pressure blocks b105 on both sides of the outer end of the water meter actuator 101 and pressed together. At this time, the sealing block 106 on the inner side of the pressure block a104 is inserted into the limiting groove a107, so that the sealing block 106 is snap-connected with the limiting groove a107, which makes it easy to install the outer shell 1 on the water meter actuator 101 for fixing, and can also increase the sealing between the outer shell 1 and the water meter actuator 101, thereby achieving a good waterproof effect.

[0043] During the use of the shell 1, a lens is provided on the shell 1 for viewing the metering value on the water meter actuator 101. Since a large amount of heat will reach the shell 1 during bathing, and after the shell 1 gets hot water, scale will form on the surface of the lens of the shell 1 over time. The protective cover 2 is flipped downward, and the protective cover 2 and the shell 1 can rotate through the rotating shaft 202 and the rotating ring 203, that is, the protective cover 2 is covered on the outside of the shell 1 to block water stains. The metering value in the lens can also be seen through the observation window 201, so as to prevent scale from forming on the surface of the lens of the shell 1 and to avoid blurring of the lens and unclear viewing of the displayed metering value on the water meter actuator 101.
