In the valve core, the filter screen 11 is arranged at the downstream of the sealing block 4 for adjusting water flow, so that the filter screen 11 is convenient to disassemble.
The sealing block 4 is arranged between the limiting ring 10 and the bottom of the cavity 5, and the outer diameter of the sealing block 4 is larger than the inner diameter of the limiting ring 10, so that the limiting ring 10 limits the movement space of the sealing block 4, the sealing block can only move between the bottom of the cavity 5 and the limiting ring 10, and the water inlet hole 2 is arranged in the space. The water outlet 3 is arranged in the downstream direction of the sealing block 4 of the limiting ring 10, namely between the top end of the sealing plug 7 and the limiting ring 10, so that a water flow channel of the valve core is formed from the water inlet 2 to the water outlet 3 through a matching channel of the sealing block 4 and the inner diameter of the limiting ring 10.

As an embodiment, since the outer diameter of the sealing block 4 is larger than the inner diameter of the limiting ring 10, the sealing block 4 can seal the degree of the channel surrounded by the inner diameter of the limiting ring 10 to block or conduct the water flow between the water inlet hole 2 and the water outlet hole 3, and the size and speed of the water flow can be adjusted.
The sealing block 4 is fixedly connected with the connecting rod 8, the connecting rod 8 passes through a channel formed by the inner diameter of the limiting ring 10, a flange 18 is arranged on the connecting rod 8, as shown in fig. 3, a spring 9 can be sleeved on the connecting rod 8 through the flange 18, and one end of the spring 9 is abutted against the flange 18; the other end of the spring 9 abuts against the bottom surface of the cavity or against the limiting ring 10 or the inner wall of the fixed connection cavity, preferably, the other end of the spring 9 abuts against the bottom surface of the cavity. The sealing plug 7 bears against the rod 8, with the spring 9 in a compressed state. When the velocity of flow of intaking of inlet opening 2 is reduced to needs, the manual rotatory sealing plug 7 of user's accessible for sealing plug 7 is toward the direction motion of keeping away from spacing ring 10, thereby spring 9 extends under the effect of its self elasticity, drives the direction motion of connecting rod 8 toward sealing plug 7, and then, sealing block 4 is under the pulling of connecting rod 8, toward the direction motion that is close to spacing ring 10, realizes reducing the water intake speed of inlet opening 2 gradually.
Among the prior art at present, in order to guarantee that the quality of water of the play water behind the muddy water valve of muddy water valve flow through is good, can install a filter screen 11 in the muddy water valve generally, this filter screen 11 is used for filtering the water that flows through muddy water valve. However, the filter net 11 needs to be replaced or cleaned after a certain period of use. Before the replacement, the user needs to close the main water gate communicating with the water path of the mixing valve and then replace the filter screen 11, which is relatively troublesome for the user.

As another embodiment, the sealing block 4 may adopt another structure to achieve the above-mentioned effect of controlling the water inlet speed of the water inlet 2. The sealing block 4 can adopt a structure with only one side surface plugging structure, namely, the structure of the sealing block 4 is only arranged aiming at the aperture size of the water inlet hole 2, and the structure is attached to the inner wall of the cavity 5 and is only used for plugging the water inlet hole 2. When a user rotates the sealing plug 7 until the sealing plug 7 is separated from the thread fit with the mounting opening 6, namely the sealing plug 7 is dismounted, the sealing block 4 moves to the tail end of the stroke under the action of the elastic force of the spring 9, the water inlet hole 2 can be just blocked by the size of the volume of the sealing block, and at the moment, the side surface, attached to the inner wall of the cavity 5, of the sealing block 4 completely covers and seals the water inlet hole 2.
When the user needs to replace the filter screen 11, the user does not need to additionally close the water gate of the external device, and the operation is more convenient. After the user changes or washs filter screen 11, the user passes through screw-thread fit to sealing plug 7 during installing port 6, sealing plug 7 supports connecting rod 8, continue rotatory sealing plug 7 this moment and make sealing plug 7 continue toward the direction motion of installing port 6, make sealing plug 7 drive connecting rod 8 overcome spring 9's elasticity and toward the motion of cavity 5 bottom, thereby make sealed piece 4 switch on the rivers passageway between inlet opening 2 and apopore 3, as a preferred embodiment, when sealed piece 4 moves to the stroke end along the direction of keeping away from sealing plug 7, the velocity of water through spacing ring 10 internal diameter can set up to reach the fastest.
