Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a variable diameter flexible pipe valve. Background Technology

[0002] Water hoses are hollow pipes made of flexible materials (such as PVC, rubber, or polyurethane). They are lightweight, pressure-resistant, and flexible, and are widely used in agricultural irrigation, industrial drainage, building water supply, and home garden irrigation. Valves are usually installed at the ends of water hoses.

[0003] In the prior art, the authorized announcement number CN214743618U discloses a portable shut-off valve device for a hose, including a shut-off valve body. Both ends of the shut-off valve body are provided with sealing blocks. The ports at both ends of the shut-off valve body are sealed by two sealing blocks. Each sealing block has a sliding groove in the middle of the side near the shut-off valve body. Each sliding groove has a locking block slidably connected inside.

[0004] Hose typically connects to valve ports via end connectors to facilitate media transport and control. However, in practical applications, hoses come in various types, weights, and materials, and more importantly, their diameters differ significantly—some are thinner, others thicker. Despite this, valve port dimensions are fixed and cannot be flexibly adjusted to accommodate different hose diameters. This leads to a problem: a specific valve can only be matched with a hose of a specific diameter, incompatible with other diameters. This design limitation greatly reduces valve applicability, necessitating the preparation of multiple valves of different specifications to accommodate hoses of varying diameters in actual operation. To address this, a variable-diameter flexible nozzle valve is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a variable diameter flexible nozzle valve to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable diameter flexible pipe valve, comprising a valve body, with connecting ports at both ends of the valve body, a valve stem installed in the middle of the valve body, a handle fixedly installed at the upper end of the valve stem, a connecting mechanism installed on the connecting ports, the connecting mechanism including a connecting pipe port connected within the connecting ports, a hexagonal nut seat fixedly installed on the connecting pipe port, a tapered interface fixedly connected to the other end of the connecting pipe port, and a locking mechanism installed on the hexagonal nut seat.

[0007] Preferably, the connecting pipe port is provided with a connecting thread, and the connecting pipe port is installed in the mating interface through the connecting thread.

[0008] Preferably, the connecting pipe opening and the tapered interface are integrally cast, and the hexagonal nut seat is welded and fixed to the connecting pipe opening.

[0009] Preferably, the tapered interface is installed at the opposite interface via a connecting pipe, and a locking nut is threadedly connected to the upper end of the valve stem, and the valve stem is fixedly installed at the upper end of the valve stem by the locking nut.

[0010] Preferably, the locking mechanism includes an outer sleeve fixedly installed on a hexagonal nut seat, with a tapered interface located inside the outer sleeve. The outer sleeve has an internal thread, and an inner sleeve is installed inside the outer sleeve. The outer wall of the inner sleeve has an external thread, and a tapered rubber plug is fixedly installed on the inner wall of the inner sleeve. A knob is fixedly installed at the end of the inner sleeve.

[0011] Preferably, the inner wall of the inner sleeve is coated with structural adhesive, and the conical rubber plug is fixedly installed inside the inner sleeve by the structural adhesive.

[0012] Preferably, the inner sleeve is connected to the outer sleeve through the engagement of internal and external threads, and the conical rubber plug fits into the conical interface.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after aligning the connecting pipe port with the mating interface of the valve body, a hexagonal nut seat can be turned with a wrench. Turning the hexagonal nut seat will rotate the connecting pipe port, tightening it into the mating interface, thereby installing the tapered interface onto the valve body. Flexible hoses of different diameters can be fitted onto the tapered interface, thus enabling the valve to connect with hoses of different diameters and improving the valve's applicability.

[0014] 2. In this application, after the hose is fitted onto the conical interface, the inner sleeve can be rotated to enter the outer sleeve. During the process of the inner sleeve entering the outer sleeve, the conical rubber plug also enters. When the conical rubber plug enters the outer sleeve, it applies pressure to the hose connected to the conical interface, causing the hose to connect tightly to the conical interface, thereby preventing the hose from detaching from the valve.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a variable diameter flexible pipe valve, including a valve body 1, with connecting interfaces 2 at both ends of the valve body 1, a valve stem 3 installed in the middle of the valve body 1, a handle 4 fixedly installed on the upper end of the valve stem 3, a connecting mechanism 5 installed on the connecting interface 2, and a locking mechanism 6 installed on the hexagonal nut seat 503. Through the cooperation of the connecting mechanism 5 and the locking mechanism 6, the valve can be connected to hoses of different diameters, improving the applicability of the valve.

[0019] like Figure 2 and Figure 3 As shown, the connecting mechanism 5 includes a connecting port 502 connected to the interface 2. A hexagonal nut seat 503 is fixedly installed on the connecting port 502. A tapered interface 504 is fixedly connected to the other end of the connecting port 502. A connecting thread 501 is provided on the connecting port 502. The connecting port 502 is installed in the interface 2 through the connecting thread 501. The connecting port 502 and the tapered interface 504 are integrally cast. The hexagonal nut seat 503 is welded and fixed to the connecting port 502.

[0020] Specifically, the connecting pipe port 502 can be precisely aligned with the pre-set mating interface 2 on the valve body 1 to ensure accurate positioning. Then, a wrench can be used to rotate the hexagonal nut seat 503 clockwise or counterclockwise. Rotating the hexagonal nut seat 503 will cause the connecting pipe port 502 to rotate accordingly, gradually tightening it and firmly fixing it inside the mating interface 2. In this way, the tapered interface 504 can be smoothly installed on the valve body 1, forming a stable connection structure.

[0021] Furthermore, the tapered connector 504 is designed to be compatible with hoses of different diameters. Specifically, hoses of different diameters can be easily fitted onto the tapered connector 504, thus achieving an effective connection between the valve and hoses of various diameters. This design not only significantly improves the valve's applicability, enabling its wide application in different working scenarios, but also greatly enhances the flexibility and convenience of connections, bringing great convenience to actual operation.

[0022] like Figure 2 and Figure 4 As shown, the locking mechanism 6 includes an outer sleeve 601 fixedly installed on a hexagonal nut seat 503, and a tapered interface 504 located inside the outer sleeve 601. An internal thread 602 is provided inside the outer sleeve 601. An inner sleeve 603 is installed inside the outer sleeve 601. An external thread 604 is provided on the outer wall of the inner sleeve 603. A tapered rubber plug 606 is fixedly installed on the inner wall of the inner sleeve 603. A knob 605 is fixedly installed at the end of the inner sleeve 603. Structural adhesive is applied to the inner wall of the inner sleeve 603. The tapered rubber plug 606 is fixedly installed inside the inner sleeve 603 by the structural adhesive.

[0023] Specifically, after the hose is fitted onto the conical interface 504, the user can rotate the inner sleeve 603, causing it to rotate along a preset track and gradually penetrate deeper into the interior space of the outer sleeve 601. During this process, the conical rubber plug 606, which is tightly connected to the inner sleeve 603, also enters the interior of the outer sleeve 601. When the conical rubber plug 606 enters the interior of the outer sleeve 601, due to its special conical design and the elastic properties of its material, it applies a uniform and continuous pressure to the hose already connected to the conical interface 504. This pressure effectively secures the hose tightly to the conical interface 504, ensuring a firm and reliable connection between the hose and the conical interface 504. This effectively prevents the hose from accidentally detaching from the valve due to external forces or other factors during use, ensuring the sealing and safety of the entire system.

[0024] Working principle: First, align the connecting pipe port 502 with the mating port 2 on the valve body 1. Then, use a wrench to rotate the hexagonal nut seat 503. Rotating the hexagonal nut seat 503 will cause the connecting pipe port 502 to rotate, thus tightening the connecting pipe port 502 into the mating port 2. Next, install the tapered port 504 onto the valve body 1. Hoses of different diameters can be fitted onto the tapered port 504 to connect the valve to hoses of different diameters, improving the valve's applicability. After the hose is fitted onto the tapered port 504, rotate the inner sleeve 603 into the outer sleeve 601. During this process, the tapered rubber plug 606 also enters the outer sleeve 601. Inside the outer sleeve 601, the tapered rubber plug 606 applies pressure to the hose connected to the tapered port 504, ensuring a secure connection and preventing the hose from detaching from the valve.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
