Embodiment 1

[0032] Such as figure 1 As shown, a valve core includes a body 2, the valve core is applied to a three-way valve body 1, the body 2 is columnar, the lower end of the valve body 1 is open, the upper end is closed, and the body 2 is rotatably arranged in the valve body 1 , the upper end of the body 2 has a valve stem 27, the valve stem 27 protrudes upwards from the valve body 1, and there is a pressure block at the upper end of the valve stem 27, the pressure block is pressed against the upper end surface of the valve body 1 to realize the valve body 2 Positioning, the outer walls of both ends of the body 2 are provided with sealing rings 4, and the sealing rings 4 are pressed against the inner wall of the valve body 1, thereby sealing both ends of the body 2, combined with figure 2 As shown, the valve body 1 has three water ports 11, the three water ports 11 are arranged in a T shape, that is, the two water ports 11 are on the same straight line, the third water port 11 is per...

Embodiment 2

[0036] The structure of the spool is basically the same as that of Embodiment 1, the difference is that Figure 7 As shown, the valve core is applied to the four-way valve body 1, and the valve body 1 is provided with four water outlets 11, and the sealing block 3 blocks one of the water outlets 11, and the two ends of the water hole 1 21 are respectively connected to two The water outlet 11 and the second water hole 22 communicate with a water outlet 11 .

Embodiment 3

[0038] The structure of the spool is basically the same as that of Embodiment 1, the difference is that Figure 8 As shown, the valve core is used in the five-way valve body 1, the body 2 is provided with a water hole 1 21 and two water holes 22, the valve body 1 is provided with five water ports 11, and the sealing block 3 seals One of the water outlets 11 is blocked, and the two ends of the first water hole 21 are connected to the two water outlets 11 respectively, and the two water holes 22 are connected to the two water outlets 11 respectively.

Abstract

The invention provides a valve plug and belongs to the technical field of valves. The valve plug solves the problem that an existing valve plug is poor in sealability. The valve plug comprises a cylindrical body; a water inflow hole I and at least one water inflow hole II which intersect and communicate are formed in the side wall of the body; the water inflow hole II is located on one side of thewater inflow hole I; a buffering cavity is formed in the part, on the other side of the water inflow hole I, of the side wall of the body; a sealing block is arranged in the buffering cavity; a partition part is arranged between the buffering cavity and the water inflow hole I; a communicating hole communicating the buffering cavity with the water inflow hole I is formed in the partition part; and the diameter of the communicating hole is less than that of the water inflow hole II. The sealability of the valve plug is better.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a valve core. Background technique [0002] The valve core is used in the valve body to control or switch the waterway. Taking the three-way valve as an example, the valve body has three ports, one in and two out or two in and one out. For one in and two out, the inlet is fixed, and The switching of different outlets is realized by the rotation of the spool. Similarly, for two inlets and one outlet, the outlet is fixed, and different inlets are realized by the rotation of the spool. When one inlet is connected to one outlet, the other outlet or inlet The spool needs to be sealed. Traditionally, the outer wall of the spool is directly pressed against the inner wall of the valve to achieve a low sealing reliability, and it is easy to leak when it is worn for a long time. [0003] In view of the above problems, the Chinese utility model patent (application number: 201420424535.7) discl...
