As shown in fig. 1-4, an angle valve, comprising: the valve comprises a valve body 1, a valve core 5 and a hand wheel 7, wherein the valve core 5 comprises a valve rod 21, a sealing ring 15 and a sealing gasket 6;

as shown in fig. 3, a valve cavity 2 is formed in the valve body 1, a water inlet flow channel 3 and a water outlet flow channel 4 are further formed on the valve body 1, the valve cavity 2 is communicated with the water inlet flow channel 3 and the water outlet flow channel 4, the water inlet flow channel 3 and the valve cavity 2 are arranged along the axis of the water supply, and a sealing baffle ring 8 is formed on the inner wall of the water inlet flow channel 3;

as shown in fig. 2 and fig. 4, the lower end of the valve rod 21 is formed with a first convex ring 9 and a second convex ring 10, a fixing space 11 is formed between the first convex ring 9 and the second convex ring 10, and a through hole is formed in the middle of the sealing gasket 6, so that the sealing gasket 6 can be sleeved on the valve rod 21 and positioned in the fixing space 11, and two ends of the sealing gasket 6 respectively abut against the first convex ring 9 and the second convex ring 10, so that constraint fixing of the sealing gasket 6 is realized.

The middle part of the valve rod 21 is provided with a threaded section 12, and the upper part is provided with a connecting part 13 for connecting with the hand wheel 7; the inner wall of the upper end of the valve cavity 2 of the valve body 1 is also provided with a thread, and the inner wall of the valve cavity 2 below the thread is a smooth sealing section;

when the sealing gasket 6 is assembled, firstly, the sealing gasket 6 is installed on the valve rod 21, the upper end of the valve rod 21 penetrates through the sealing baffle ring 8 from the water inlet flow channel 3 until the upper end penetrates out of the valve body 1, the threaded section 12 abuts against the threaded lower end of the inner wall, then the valve rod 21 is rotated, the threaded section 12 is connected with threads, the installation of the valve rod 21 in the valve body 1 is realized, then the hand wheel 7 is fixed on the upper end of the valve rod 21 protruding out of the valve body 1, then the hand wheel 7 can be held to drive the valve rod 21 to rotate in the valve body 1, the up-and-down movement is realized, the sealing gasket 6 is movably abutted against the end face of the sealing baffle ring 8, which faces the water inlet flow channel 3, the valve rod 21 moves downwards, and the conduction of the water inlet flow channel 3-valve cavity 2 and the water outlet flow channel 4 can be opened.

According to the utility model, the valve core 5 is inserted into the valve cavity 2 from the water inlet flow channel 3 and is in threaded connection, so that the valve core 5 is mounted on the valve body 1, and meanwhile, the sealing gasket 6 is movably abutted against the lower end face (the end face facing the water inlet flow channel 3) of the sealing retainer ring, so that the problem that the valve core 5 is separated from the valve body 1 in the use process is avoided, and the mounting of a gland is omitted after the design, so that the mounting is simplified.

Meanwhile, the outer diameter of the first convex ring 9 is larger than or equal to that of the sealing baffle ring 8 and larger than that of the second convex ring 10, and the first convex ring 9 can completely block the lower end face of the sealing gasket 6, so that when water enters, water flow is impacted at the lower end of the first convex ring 9 instead of directly impacting the end face of the sealing gasket 6, and therefore, even after the sealing gasket is used for a long time, the sealing gasket 6 is not damaged due to the impact of the water flow, and the sealing performance can be guaranteed.

A sealing groove 14 is also formed in the outer wall of the valve rod 21 between the threaded section 12 and the second convex ring 10, and the sealing groove 14 is used for installing a sealing ring 15.

After the valve rod 21 is installed, the sealing ring 15 can seal a gap between the valve rod 21 and the inner wall of the valve cavity 2, the valve rod 21 moves up and down, the sealing ring 15 also moves on the sealing section, water is guaranteed not to flow out of the gap between the valve rod 21 and the valve cavity 2 when the valve rod 21 is adjusted, and the overall tightness of the valve is guaranteed.

In order to restrain the valve rod 21 so that the valve rod 21 cannot be separated from the valve body 1 from the water inlet channel, a clamping groove 16 is formed on the outer wall of the valve rod 21 between the connecting part 13 and the threaded section 12, a clamping spring 17 is arranged in the clamping groove 16, and the clamping spring 17 is movably abutted against the end face of the valve body 1.

When the clamping spring 17 abuts against the end face of the valve body 1, the valve is then in the maximum open position.

In order to further ensure the tightness, an annular raised line 18 is formed on the upper end surface of the sealing gasket 6 in a protruding manner, and the annular raised line 18 is movably abutted against the lower end surface of the sealing baffle ring 8.

The lower end face of the sealing baffle ring 8 is provided with an annular flow guiding sealing surface 19, and the inner diameter end of the annular flow guiding sealing surface 19 is higher than the outer diameter end of the annular flow guiding sealing surface 19, so that the annular flow guiding sealing surface 19 can play a role in guiding water flow when the water flow impacts the lower end of the sealing baffle ring 8, and the loss of the flowing water flow is reduced as much as possible.

As shown in fig. 3, the lower end of the convex ring one 9 is convexly provided with a water guiding part 20, and the water entering in the water inlet flow channel 3 flows around the water guiding part 20 through the water guiding part 20.

Thus, when the water flow impacts on the water guide part 20, the water can be guided, the flowing power of the water is further reduced, and the water flow rate is ensured.

The water guide 20 may be of hemispherical or conical design.
