Description

Technical Field

[0001] This utility model belongs to the field of high-pressure water pipe valve technology, and relates to a multi-functional high-pressure water pipe valve. Background Technology

[0002] Existing high-pressure water pipe valves suffer from significant drawbacks due to their internal structural design not adequately considering the need for convenient disassembly and cleaning. Core components such as the valve body, valve core, and valve stem are often manufactured using integrated casting or welding processes, and some critical connection points lack standardized disassembly interfaces. This necessitates complete valve removal and disassembly using specialized tools during cleaning, greatly increasing operational complexity and time costs. These shortcomings stem from traditional design concepts that prioritize pressure resistance and sealing performance while neglecting ease of maintenance. Furthermore, the rigidity requirements under high-pressure conditions limit the application of modular components, and cost-saving manufacturing processes often omit detachable connection structures. Conventional solutions include periodic complete disassembly followed by ultrasonic cleaning or chemical solvent immersion, but these methods require system shutdown, disrupting continuous operation, and chemical solvents may corrode non-metallic seals. Online flushing attempts to remove impurities by reverse pressurization or introducing high-pressure steam, but the complexity of the flow channel structure prevents thorough removal of residues in dead zones, and pressure fluctuations may even cause impurities to embed into the sealing surface. Therefore, a multifunctional high-pressure water pipe valve is urgently needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional high-pressure water pipe valve to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a multi-functional high-pressure water pipe valve, including: a valve handle and an inner sealing seat, wherein a set of locking bolts for locking the valve handle at the middle position of the upper end is provided, and a set of shafts for synchronous rotation with the valve handle is provided inside the locking bolts;

[0005] The lower end of the shaft is provided with a set of external connecting threads for driving the valve core to move up and down. The middle position of the shaft is provided with a set of internal thread core seats for positioning and rotating connection with the shaft. The internal thread core seat is a hollow structure with an internal connecting screw groove for threaded connection with the shaft. The shaft passes through the middle position of the internal thread core seat. The outer side of the internal thread core seat is provided with a set of upper connecting seats for limiting the position of the internal thread core seat.

[0006] In a preferred embodiment, the lower end of the upper connecting seat is provided with a set of lower sealing rings for sealing and fitting with the valve seat. The lower end of the lower sealing rings is sealed and fitted with the upper end of the valve seat, and is fixed in a vertical direction by two sets of bolts.

[0007] In a preferred embodiment, the valve seat has a hollow structure, and both its inner and outer surfaces are coated with an anti-rust and anti-oxidation coating. A set of inlet pipes for introducing water is provided on the upper right side of the valve seat. In actual use, first loosen the locking bolt above the valve handle to release the fixing restriction on the shaft. When the valve handle is held and rotated clockwise, the shaft drives the inner thread core seat downward through the external connecting thread, causing the valve core to move downward and close the water flow channel. Rotating counterclockwise will cause the valve core to lift up and open the channel. During operation, it is necessary to ensure that the inner thread core seat and the upper connecting seat maintain stable engagement, and that the lower sealing ring and the valve seat always maintain sealed contact. After the water source is connected through the inlet pipe, the water flows through the valve cavity and is output from the outlet pipe. High-pressure sealing is achieved through the precise cooperation between the valve core and the inner sealing core seat.

[0008] In a preferred embodiment, the lower end of the valve seat is provided with a set of valve shells, the lower left side of the valve shells is provided with a set of outlet pipes for discharging water, and the inside of the valve shells is provided with a set of valve chambers for storing water. The valve shells and the valve seat are an integral structure.

[0009] In a preferred embodiment, the lower end of the valve body is provided with a set of valve bases to facilitate cleaning of the valve cavity by the user. The valve bases are sealed and fitted to the bottom of the valve body and are fixed by a flange. The inside of the inlet pipe is interconnected with the inside of the valve cavity and the inside of the outlet pipe.

[0010] In a preferred embodiment, the water inlet pipe is isolated from the inside of the valve cavity by a valve core and an inner sealing seat. A set of valve cores is provided at the lower end of the shaft. The valve cores are made of a rubber material and have a trapezoidal cross-section on the front side.

[0011] In a preferred embodiment, the lower cross-sectional length of the valve core is less than the upper cross-sectional length of the valve core. An inner sealing seat is provided on the outer side of the lower end of the valve core to maintain its seal. The outer side of the inner sealing seat is connected and fixed to the bottom inner side of the valve seat. A rubber sealing ring is provided inside the inner sealing seat. The inner side of the upper end of the rubber sealing ring is sealed and fitted to the outer side of the lower end of the valve core. In actual use, during adjustment, the trapezoidal structure of the valve core changes its water passage cross-section with the lifting height, achieving precise flow control. When closing, rotating the handle clockwise presses down the valve core, and its smaller lower cross-section preferentially contacts the rubber sealing ring to form a preliminary seal. Continue rotating until the valve core is fully pressed into the inner sealing seat to achieve a high-pressure seal. After the operator disassembles the valve seat flange connection, the valve cavity can be thoroughly cleaned.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: First, loosen the locking bolt above the valve handle to release the fixation restriction on the shaft. When the valve handle is held and rotated clockwise, the shaft drives the internal thread core seat downward through the external connecting thread, causing the valve core to move downward and close the water flow channel. Rotating counterclockwise causes the valve core to lift up and open the channel. During operation, it is necessary to ensure that the internal thread core seat and the upper connecting seat maintain stable engagement, and the lower sealing ring and the valve seat always maintain sealed contact. After the water source is connected through the water inlet pipe, the water flows through the valve cavity and is output from the water outlet pipe. High pressure sealing is achieved through the precise cooperation between the valve core and the internal sealing core.

[0013] In actual use, during the adjustment process, the trapezoidal structure of the valve core will change the water passage cross section with the lifting height to achieve precise flow control. When closing, rotate the handle clockwise to press the valve core down. Its lower end, with a smaller cross section, will first contact the rubber sealing ring to form a preliminary seal. Continue rotating until the valve core is fully pressed into the inner sealing seat to achieve a high-pressure seal. After the operator disassembles the valve base flange connection, the valve cavity can be thoroughly cleaned. Attached Figure Description
