Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a multifunctional heavy-duty faucet. Background Art

[0002] Heavy-duty faucets are faucets used in industrial and commercial locations. They are made of stronger materials and can withstand higher water pressures. They are suitable for situations where a strong water flow is required, such as agricultural irrigation, washing vehicles or equipment, etc.

[0003] A Chinese patent discloses a faucet (authorization publication number CN110792796B). The patented technology includes a faucet body and a locking screw. The outer wall of the faucet body is rotatably mounted with a water outlet connector. The water outlet connector is provided with a threaded hole. When the water outlet connector is rotated to a set angle relative to the faucet body, the locking screw is screwed into the threaded hole and abuts against the outer wall of the faucet body to maintain the set angle. A first sealing ring is also provided between the outer wall of the faucet body and the inner wall of the water outlet connector. The present invention can achieve 360-degree rotation of the water outlet connector, can effectively adapt to the installation of water-passing connectors in different installation directions, and can effectively meet customer needs.

[0004] This patented technology can adapt to connectors with different installation directions when used, but it still has some shortcomings when used. It has a single function and cannot be used for adapter connectors. It also does not have the function of filtering the transported water flow. When it needs to be connected to other equipment or pipelines, it is not flexible enough to use. When water filtering is required, additional filter components need to be installed. It cannot be used directly when the water quality is poor. Therefore, those skilled in the art provide a multifunctional heavy-duty faucet to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a multifunctional heavy-duty faucet, comprising a heavy-duty faucet body,

[0008] The heavy-duty faucet body includes a valve pipe, symmetrically distributed valve seats located inside the valve pipe, a spherical valve core located between the valve seats, a connecting pipe located at one end of the valve pipe, an inner plastic pipe located inside the connecting pipe, a sealing seat located inside the upper end of the valve pipe, a valve stem rotatably mounted inside the sealing seat and connected to the spherical valve core at the lower end, a threaded joint located at one end of the valve pipe, and a plastic-lined pipe located inside one end of the connecting pipe;

[0009] as well as;

[0010] A filtering structure, a filter element located inside the spherical valve core, a U-shaped tube and a sewage pipe installed inside the valve pipe, a second threaded joint located at one end of the sewage pipe, and a threaded sleeve rotatably sleeved on the outer wall of the second threaded joint.

[0011] Furthermore, a sealing ring is provided inside the valve seat, the spherical valve core is rotatably mounted inside the sealing ring, and the lower end of the spherical valve core is rotatably mounted inside the valve pipe;

[0012] Specifically, when the ball valve rotates, the sealing ring is sealed against the valve seat to prevent water leakage. The ball valve is rotatably installed inside the valve pipe.

[0013] Furthermore, a handle is provided on the upper end of the valve stem, and a walking rod is provided on the outer wall of the handle;

[0014] Specifically, when the valve stem rotates, force is applied by grasping the handle, and the walking rod rotates along with the valve stem handle.

[0015] Furthermore, a second limiting rod is provided on the outer wall of one side of the sealing seat, and a first limiting rod is provided on the outer wall of the rear end of the sealing seat. The traveling rod is located between the second limiting rod and the first limiting rod, and the angle between the first limiting rod and the second limiting rod and the center of the valve stem at the same horizontal height is ninety degrees.

[0016] Specifically, the limiting rod 1 and the limiting rod 2 limit the rotation of the travel rod so that the valve stem can only rotate ninety degrees.

[0017] Furthermore, the sewage pipe corresponds to the through-opening of the valve pipe at one end of the U-shaped pipe, and the corresponding positions of the sewage pipe and the U-shaped pipe through the valve pipe are located at the front and rear ends of the spherical valve core;

[0018] Specifically, when the spherical valve core closes the valve pipe, the water flow inside the U-shaped pipe passes through the spherical valve pipe and acts on the inside of the sewage pipe.

[0019] Furthermore, a limiting ring is sleeved on the outer wall of the sewage pipe, a sealing ring 1 is embedded in the limiting ring, and a sealing ring 2 is embedded in the inner wall of the front end of the threaded sleeve;

[0020] Specifically, the limiting ring supports one end of the threaded sleeve, the first sealing ring improves the sealing performance between the limiting ring and the threaded sleeve, and the second sealing ring improves the sealing performance at the joint between the threaded sleeve and the second threaded joint.

[0021] Furthermore, both ends of the valve seat are provided with a first guide surface that fits the inner wall of the valve pipe, and one end of the plastic-lined pipe is provided with a second guide surface that fits the inner wall of the connecting pipe;

[0022] Specifically, the first guide surface causes water to flow backwards, thereby reducing the resistance of the valve seat to the water flow, and the second guide surface causes water to flow backwards inside the pipe, thereby reducing the resistance exerted by the fault of the plastic-lined pipe on the transported water.

[0023] 2. Beneficial effects

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] The utility model has a spherical valve core installed in the valve tube to control the opening and closing of the faucet body. The spherical valve core is provided with a filter element to filter impurities in the water, thereby improving the quality of the water being transported. It is convenient for direct use in places where high water quality requirements are required and no water treatment is provided.

[0026] At the same time, after the spherical valve core is rotated and closed, it is connected to the U-tube and the drain pipe that are connected to the valve pipe. The water pressure in the pipeline is passed to the inside of the spherical valve core through the U-tube, and the back of the spherical valve core is flushed when water is transported. The impurities and foreign matter on one side of the filter element and inside the spherical valve core are intercepted and flushed into the drain pipe. The drain pipe is opened regularly to clean the dirt, and the filter element is self-cleaning, which reduces maintenance requirements and maintenance costs. The heavy-duty water nozzle can be used for faucets, and can be used for pipeline docking through the plastic-lined pipe on the basis of hot-melt welding. It can filter and self-clean during use, realizing multi-functional use.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
