Description

Technical Field

[0001] This utility model relates to the field of water heating valve technology, and in particular to a leak-proof and sealing water heating valve assembly. Background Technology

[0002] Plumbing valves are crucial components in plumbing systems, used to control water flow and regulate flow rate and pressure. They typically consist of a valve body, valve core, valve stem, and valve cover, and their primary function is to control water flow and enable on / off switching. Plumbing valves are widely used in building water supply and drainage systems, heating systems, and bathroom-related facilities to control water flow, connect pipes, and handle sewage. They ensure the normal operation and safe use of the system and are an indispensable part of plumbing systems.

[0003] Currently, a Chinese patent discloses a water valve that is easy to assemble (authorization announcement number CN221034166U). This utility model includes a valve body with connecting pipes symmetrically arranged at both ends of the valve body. A valve seat is installed inside the valve body, and a valve plug is provided at the top of the valve seat. A handle is installed on the top of the valve plug. Two sets of connecting pipes are symmetrically arranged at both ends of the valve seat. The connecting pipes and the valve seat are internally connected. An external component is installed on the connecting pipe. The external component includes an external threaded sleeve, which is installed on the pipe body. An elastic clamp is provided at the end of the external threaded sleeve away from the interface. A clamping ring is installed above the elastic clamp. A sealing device is provided inside the connecting pipe. This utility model provides a water valve that is easy to assemble. By installing an external threaded sleeve on the pipe body, the external threaded sleeve and the connecting pipe are threadedly connected. A clamping ring is installed at one end of the external threaded sleeve, which facilitates the assembly of the water valve. However, the above device has the following problems when in use.

[0004] However, these valves cannot provide an emergency seal when leaks occur, posing a significant safety hazard. Utility Model Content

[0005] Therefore, it is necessary to provide leak-proof and sealing water valve components to address the problem that valves cannot be sealed in an emergency when leaks occur.

[0006] A leak-proof, sealed plumbing valve assembly includes: a ball valve, an electric actuator mounted on the ball valve, flanges at both ends of the ball valve, and a leak-proof mechanism mounted on the ball valve; the leak-proof mechanism includes a guide frame fixedly connected to the inside of the ball valve near the inlet, a fixed plate fixedly connected to one side of the guide frame, a guide rod slidably connected to the fixed plate, a sealing plug fixedly connected to one end of the guide rod, a powerful magnet fixedly connected to one side of the sealing plug, and an electromagnet corresponding to the powerful magnet fixedly mounted on the fixed plate.

[0007] In one embodiment, a spring is provided between the fixing plate and the sealing plug, the spring is sleeved on the guide rod, and the two ends of the spring abut against the surface of the sealing plug and the fixing plate, respectively.

[0008] In one embodiment, both the guide frame and the sealing plug are frustum-shaped, and a sealing ring is fixedly connected to the surface of the sealing plug.

[0009] In one embodiment, the electromagnet is electrically connected to an external leak detection sensor.

[0010] In one embodiment, the frustum-shaped conical surface of the guide frame matches the frustum-shaped conical surface of the sealing plug, and the two form a line contact seal when closed.

[0011] In one embodiment, the sealing ring is a V-shaped PTFE reinforced sealing ring, which expands radially after being compressed to fill the sealing gap.

[0012] In one embodiment, the electric actuator includes a geared motor and a connecting rod. The geared motor drives the connecting rod to rotate, and the connecting rod is connected to the valve stem of the ball valve to drive the ball valve to open and close.

[0013] In one embodiment, the base of the sealing ring is embedded in a dovetail groove circumferentially within the sealing plug, and the lip is inclined toward the water inlet side.

[0014] Beneficial effects

[0015] A leak-proof mechanism is installed. When the ball valve core leaks water, the electromagnet is energized and generates a magnetic force. This force is opposite to the magnetic force of the strong magnet and attracts the strong magnet. This causes the strong magnet to move the sealing plug closer to the guide frame. The sealing plug then squeezes and seals the guide frame, thus sealing the ball valve in an emergency and preventing damage.

[0016] A guide rod and a spring are installed. During daily use, the spring pushes the sealing plug out of the guide frame to achieve a normally open state without power. When there is a leak, the electromagnet is energized to reduce energy consumption. Attached Figure Description

[0029] The following is combined with Figures 1-4 This invention describes a leak-proof, sealing type water valve assembly.

[0030] In one embodiment, a leak-proof sealing type plumbing valve assembly includes: a ball valve 100, an electric actuator 110 mounted on the ball valve 100, flanges 111 at both ends of the ball valve 100, and a leak-proof mechanism 200 mounted on the ball valve 100; the leak-proof mechanism 200 includes a guide frame 210 fixedly connected to the inside of the ball valve 100 near the inlet, a fixing plate 211 fixedly connected to one side of the guide frame 210, a guide rod 212 slidably connected to the fixing plate 211, a sealing plug 213 fixedly connected to one end of the guide rod 212, a powerful magnet 216 fixedly connected to one side of the sealing plug 213, and an electromagnet 215 corresponding to the powerful magnet 216 fixedly mounted on the fixing plate 211.

[0031] like Figure 3 As shown, a spring 214 is provided between the fixing plate 211 and the sealing plug 213. The spring 214 is sleeved on the guide rod 212, and its two ends abut against the surfaces of the sealing plug 213 and the fixing plate 211, respectively. The electromagnet 215 is electrically connected to an external water leakage detection sensor.

[0032] In this embodiment, the ball valve 100 is installed on the pipeline via flanges 111 at both ends, and the ball valve 100 is opened and closed by an electric actuator 110. The leak-proof mechanism 200 is installed near the water inlet. Under the action of the spring 214 and guide rod 212, the sealing plug 213 overcomes the water pressure and moves away from the guide frame 210, thus ensuring water flow. When the ball valve 100 is closed, if the external leak detection sensor detects a leak, the electromagnet 215 is energized, generating a magnetic force that attracts the strong magnet 216. The strong magnet 216 drives the sealing plug 213 to move inwards towards the guide frame 210, where it presses tightly against the guide frame 210, achieving a seal and providing emergency treatment at the water inlet to prevent subsequent property damage caused by leaks.

[0033] like Figure 4 As shown, both the guide frame 210 and the sealing plug 213 are frustoconical in shape, and a sealing ring 220 is fixedly connected to the surface of the sealing plug 213. The frustoconical surface of the guide frame 210 matches the frustoconical surface of the sealing plug 213, forming a line contact seal when they are closed. The sealing ring 220 is a V-section PTFE reinforced sealing ring, which expands radially after being compressed to fill the sealing gap. The base of the sealing ring 220 is embedded in the dovetail groove circumferentially of the sealing plug 213, and the lip is inclined towards the water inlet side.

[0034] In this embodiment, the two components are in line contact, increasing the contact area. When closed, they form an annular line contact band with a width of 0.5-0.8 mm, thereby improving the sealing performance between the guide frame 210 and the sealing plug 213. Fluid pressure drives the lip to expand radially, filling the micro-gaps outside the line contact band. The inclined lip design converts the fluid pressure into positive pressure on the sealing surface, sealing the inlet.

[0035] like Figure 1 As shown, the electric actuator 110 includes a geared motor and a connecting rod. The geared motor drives the connecting rod to rotate, and the connecting rod is connected to the valve stem of the ball valve 100, driving the ball valve 100 to open and close.

[0036] In this embodiment, the geared motor drives the connecting rod to rotate, and the rotation of the connecting rod drives the valve stem to rotate, thereby rotating the valve core and realizing the opening and closing of the ball valve 100.

[0037] Working principle: When water is flowing, the electric actuator 110 drives the connecting rod to rotate, which in turn drives the valve stem to rotate the valve core of the ball valve 100 to the open position. The preload of the spring 214 is greater than the thrust of the inlet water pressure on the sealing plug 213, and the sealing plug 213 is pushed away from the guide frame 210. Water flows through the annular gap between the guide frame 210 and the sealing plug 213. When an external sensor detects a leak in the pipeline, the electromagnet 215 is energized within 0.1 seconds and generates an attraction force to attract the strong magnet 216. The sealing plug 213 moves axially along the guide rod 212, and the conical surface presses against the guide frame 210, effectively suppressing the expansion of the leak.

[0038] It should be noted that the electromagnet 215 and the strong magnet 216 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electromagnet 215 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
