Description

Technical Field

[0001] This utility model relates to the field of PE pipe valves, and in particular to an antifreeze PE pipe valve. Background Technology

[0002] PE pipeline valves are key components that use polyethylene (PE) as the core valve body material (some parts such as valve cores and seals may use other compatible materials). They are used to control the opening and closing, flow regulation or pressure control of fluids (water, chemical liquids, gases, etc.) in PE pipeline systems. Their core advantages lie in the corrosion resistance, lightness and good physical properties of PE material. They widely replace traditional metal valves and are suitable for pipeline systems in many fields such as municipal, construction, agriculture and industry. When the valve is not in use, moisture and other materials may remain inside, which can easily cause the valve to become damp. Water can corrode the valve, and water residue inside the valve can freeze, causing expansion and damage. In cold winters, the valve is prone to low-temperature brittle cracking. Therefore, we propose an antifreeze PE pipe valve. Utility Model Content

[0003] The main purpose of this utility model is to provide an antifreeze PE pipe valve, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A frost-resistant PE pipe valve includes a valve body, a support base fixedly installed on the lower surface of the valve body, and heating structures fitted on both sides of the valve body, wherein there are two sets of heating structures.

[0005] Furthermore, the valve body includes an inlet, a sloping plate, a first drain outlet, a ball, a shell, and a discharge outlet. The inlet is fixedly installed on one side of the shell, and the discharge outlet is fixedly installed on the other side of the shell. A ball is embedded inside the shell, and sloping plates are embedded on both sides of the ball inside the shell. There are two sets of sloping plates. A first drain outlet is opened on the lower surface of the shell between the sloping plates and the ball.

[0006] Furthermore, the support base includes an outer frame, a water tank, a second drain outlet, an embedding groove, an electric push rod, a drain hole, a sealing gasket, and a baffle. The inner side of the outer frame has water tanks on both sides, and the upper surface of the outer frame above the water tanks has a second drain outlet. The two sides of the outer frame have drain holes in two sets. The inner side of the outer frame above the drain holes has an embedding groove, and an electric push rod is embedded in each embedding groove. The output end of each electric push rod is fixedly connected to a baffle, and a sealing gasket is fitted onto the surface of each baffle.

[0007] Furthermore, the outer frame is fixedly installed on the lower surface of the outer casing, and the second drain outlet is located below the first drain outlet.

[0008] Furthermore, the heating structure includes an electric heating element, a protective cover, and a heat-conducting plate. The electric heating element is embedded inside the protective cover, and there are multiple sets of electric heating elements.

[0009] Furthermore, the protective covers are respectively fitted onto the surfaces of the inlet and outlet, and are fixedly installed with the outer shell. The heat-conducting plate is located inside the protective cover and is in contact with the side of the outer shell.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: With its sloping panel and first drain outlet, the valve is designed to prevent moisture from remaining inside when it is not in use, thus helping to maintain the cleanliness of the valve's interior. The support base can support the valve body and seal the drain hole, thus enabling the smooth flow of water and other media when the valve is opened. The heating structure allows the outer casing to be heated, thereby raising the internal temperature of the casing and preventing the valve from freezing in cold winters. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] Reference Figure 1-5 A PE pipe valve for preventing freezing includes a valve body 1, a support base 2 fixedly installed on the lower surface of the valve body 1, and heating structures 3 sleeved on both sides of the valve body 1, wherein there are two sets of heating structures 3. Specifically, the valve body 1 controls the flow of the medium, the support base 2 supports the valve body 1 and can seal the inside of the valve body 1 to facilitate water drainage, the heating structure 3 heats the valve body 1 to prevent the valve body 1 from freezing, the equipment is powered by an external power supply, and the wires need to be connected to a waterproof junction box and controlled by external equipment.

[0015] In a preferred embodiment, the valve body 1 includes an inlet 101, a sloping plate 102, a first drain outlet 103, a ball 104, a shell 105, and a discharge outlet 106. The inlet 101 is fixedly installed on one side of the shell 105, and the discharge outlet 106 is fixedly installed on the other side of the shell 105. The ball 104 is embedded inside the shell 105. Sloping plates 102 are embedded on both sides of the ball 104 inside the shell 105. There are two sets of sloping plates 102. The lower surface of the shell 105 is provided with a first drain outlet 103 between the sloping plate 102 and the ball 104. Specifically, the water enters the interior of the outer shell 105 through the inlet 101 and outlet 106, and is intercepted by the ball 104, thus closing the valve. When the ball 104 rotates 90 degrees, the water can flow and be discharged from the outlet 106, thus opening the valve. Since the inclined plate 102 is located at the bottom of the outer shell 105, the water flows downward above the inclined plate 102 and will not remain inside the outer shell 105. The water is discharged from the first drain outlet 103. The outer shell 105, the inlet 101 and the outlet 106 are all made of metal.

[0016] In a preferred embodiment, the support base 2 includes an outer frame 201, a water tank 202, a second drain outlet 203, an embedding groove 204, an electric push rod 205, a drain hole 206, a sealing gasket 207, and a baffle 208. The outer frame 201 has water tanks 202 on both sides inside. The upper surface of the outer frame 201 above the water tanks 202 has a second drain outlet 203. The two sides of the outer frame 201 have drain holes 206, which are in two sets. The outer frame 201 has embedding grooves 204 above the drain holes 206 inside. An electric push rod 205 is embedded in the embedding groove 204. The output end of the electric push rod 205 is fixedly connected to the baffle 208. A sealing gasket 207 is fitted on the surface of the baffle 208. Specifically, by placing the second drain outlet 203 below the water tank 202, and placing the embedding groove 204 and drain hole 206 on one side of the outer frame 201, the second drain outlet 203, water tank 202, drain hole 206, and embedding groove 204 are connected. When the electric push rod 205 is activated, the electric push rod 205 extends, causing the baffle 208 to move downward and close the drain hole 206. The baffle 208 is sealed by the sealing gasket 207, preventing water from seeping out of the drain hole 206. When the electric push rod 205 shortens, the baffle 208 moves upward into the embedding groove 204, opening the drain hole 206, allowing water to drain out. The two sets of electric push rods 205 are controlled by a synchronous controller of model ZQ803SA, thus achieving synchronous operation of the two sets of electric push rods 205.

[0017] In a preferred embodiment, the outer frame 201 is fixedly installed on the lower surface of the outer casing 105, and the second drain outlet 203 is located below the first drain outlet 103; Specifically, by fixing the outer frame 201 to the lower part of the outer casing 105, the second drain outlet 203 is positioned directly below the first drain outlet 103, allowing water discharged from the first drain outlet 103 to enter the interior of the water tank 202 through the second drain outlet 203.

[0018] In a preferred embodiment, multiple sets of heating tubes 301 are embedded inside the protective cover 302. Specifically, the heating element 301 is protected by a protective cover 302, and heating is achieved by the heating element 301. The heating element 301 is model SRY6-1 and can be heated when powered on.

[0019] In a preferred embodiment, the protective cover 302 is respectively fitted onto the surfaces of the inlet 101 and the outlet 106, and is fixedly installed with the outer shell 105. The heat-conducting plate 303 is located inside the protective cover 302 and is in contact with the side of the outer shell 105. Specifically, by fixing the protective cover 302 to the surface of the inlet 101 and the outlet 106 and installing it to the outer shell 105, the heat-conducting plate 303 contacts the outer shell 105, so that the heat generated by the heating element 301 is absorbed by the heat-conducting plate 303. Since the outer shell 105 is made of metal, it can absorb the heat on the heat-conducting plate 303, thereby raising the temperature inside the outer shell 105 and thus achieving antifreeze.

[0020] It should be noted that during normal valve operation, water enters the housing 105 through the inlet 101 and exits through the outlet 106. At this time, the electric push rod 205 extends, and the baffle 208 and sealing gasket 207 are positioned inside the drain hole 206, meaning the drain hole 206 is blocked. Even if a small amount of water is discharged through the first drain port 103, there will be no leakage. When the valve is not in use, the residual water inside the housing 105 is discharged through the first drain port 103 under the action of the inclined plate 102. Water enters the interior of the water tank 202 through the second drain outlet 203. At this time, the electric push rod 205 is in a shortened state, that is, the baffle 208 is inside the embedded groove 204, and the water can be discharged through the drain hole 206. In order to save resources, the water discharged through the drain hole 206 can be collected. When the ambient temperature of the valve is low, the electric heating tube 301 is turned on. The heat conduction plate 303 absorbs the heat of the electric heating tube 301 and conducts it to the outer shell 105, thereby heating and preventing freezing inside the outer shell 105.

[0021] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
