[0002] A one-way throttle valve is a type of valve widely used in speed regulation and delay circuits of hydraulic control systems to control fluid flow. A one-way throttle valve typically consists of a valve body, valve sleeve, valve core, spring, and valve ball. The valve ball can move in one direction under the action of the spring.
[0003] The two ends of the one-way throttle valve are connected to a connector by screws, and one end of the connector is fixed to a pipe. However, since the connector and the one-way throttle valve are fixed by screws, there is no limiting mechanism, so it is impossible to limit the movement between the connector and the one-way throttle valve. This results in low stability and inconvenience in installing the one-way throttle valve.
[0004] Therefore, this utility model provides a one-way throttle valve structure. Utility Model Content

Grooves are opened inside both ends of the limiting frame 5, and one end of the connector 2 is engaged inside the groove. An external spring 12 is fixedly installed between the bottom end of the valve body 1 and the limiting frame 5. Under the tension of the external spring 12, the limiting frame 5 is in close contact with the bottom of the valve body 1, and the limiting frame 5 limits the connector 2 through its two ends and the groove, which can improve the stability between the connector 2 and the valve body 1 and has high practicality.
[0022] In this embodiment, a fixing seat 11 is screwed into the interior of one end of the valve body 1. An inner spring is fixedly installed on the outer side of one end of the fixing seat 11. A valve ball 10 is installed between one end of the inner spring and the inner wall of the valve body 1. A mounting seat 6 is screwed into the top of the valve body 1. An adjusting screw 7 is screwed into the interior of the mounting seat 6. A knob 8 is fixedly installed at the top of the adjusting screw 7. A valve core 9 is limited to rotate at the bottom of the adjusting screw 7. A throttling channel is provided above the valve ball 10 corresponding to the inner side of the valve body 1. The valve core 9 is slidably disposed inside the top of the throttling channel. A sealing layer is fixedly provided on the outer wall of the valve core 9. A sealing ring is fixedly provided on the inner wall of the valve body 1 corresponding to the outer side of the valve core 9. The inner spring facilitates the limiting of the valve ball 10, thereby facilitating one-way sealing of the fluid. The knob 8 and the adjusting screw 7 facilitate the raising and lowering adjustment of the valve core 9, thereby controlling the flow rate of the fluid.
[0023] In this embodiment, the valve body 1 and the connector 2 are disposed between the two ends of the limiting frame 5. The connector 2 and the valve body 1 are fitted with an elastic washer 3. A washer is provided between the mounting base 6 and the valve body 1. The elastic washer 3 can improve the sealing between the connector 2 and the valve body 1. The two ends of the limiting frame 5 can conveniently limit the connector 2, which can improve the stability of the connector 2.
[0024] In this embodiment, the slide rod 13 is L-shaped. A fixing hole 14 is provided inside the bottom end of the mounting plate 4. The slide rod 13 and the limiting groove are symmetrically arranged on both sides of the fixing hole 14. Mounting grooves are symmetrically provided on both sides of the fixing hole 14 below. A locking rod 15 is slidably mounted inside the mounting groove. Both ends of the locking rod 15 are arc-shaped. A limiting spring is fixedly installed between the outer side of one end of the locking rod 15 and the inner wall of the mounting groove. A corresponding locking rod 15 is mounted on the side wall of the bottom end of the slide rod 13. A slot 16 is provided at position 5. The slot 16 is on the same straight line as the central axis of the lever 15. One end of the lever 15 is set inside the fixing hole 14. The limiting frame 5 can be limited by the limiting groove and the sliding rod 13, which facilitates the lifting and lowering adjustment of the limiting frame 5. By squeezing the lever 15, the bottom end of the lever 15 can be locked inside the slot 16, which facilitates the fixing of the sliding rod 13, thereby fixing the limiting frame 5 and improving the stability of the limiting frame 5, which facilitates the subsequent limiting of the connector 2.
[0025] When using this one-way throttle valve structure, pull down the limiting bracket 5. The limiting bracket 5 drives the slide rod 13 to slide inside the limiting groove. The limiting bracket 5 also pulls down the outer spring 12. The connector 2 is screwed onto both ends of the valve body 1 and tightened. Release the limiting bracket 5. Under the tension of the outer spring 12, the limiting bracket 5 moves upward and drives the slide rod 13 to slide inside the limiting groove. The two ends of the limiting bracket 5 engage and limit the connector 2. At the same time, the limiting bracket 5 blocks both sides of the connector 2. After installation, the mounting plate 4 is brought into contact with the installation position (wall or mounting bracket). Bolts are installed inside the fixing hole 14. The bolts press the locking rod 15 through the arc end. The locking rod 15 slides inside the mounting groove and compresses the limiting spring. The other end of the locking rod 15 is inserted into the corresponding locking groove 16 to facilitate the fixing of the slide rod 13. The sliding rod 13 facilitates the fixing of the limiting bracket 5, which can improve the stability of the limiting bracket 5 and the stability of the structure. It is highly practical.
