At this time, the rotating part 31 also stops rotating, and the valve needle assembly 20 no longer moves further.

In some embodiments of the present invention, as shown in Figure 1, the valve needle assembly 20 includes a valve stem 21, a valve core 22 and an elastic member 23. The valve stem 21 is fixedly connected to the driving assembly 30. When the driving assembly 30 rotates, the driving assembly 20 rotates. The assembly 30 can drive the valve stem 21 to rotate. At this time, the valve stem can rotate and move back and forth in the valve seat assembly 10. The valve core 22 cooperates with the valve stem 21 to be driven by the valve stem 21. When the valve stem 21 is in the valve seat assembly When moving back and forth in the valve seat assembly 10, the valve stem 21 can drive the valve core 22 to reciprocate in the valve seat assembly 10, so that the valve core 22 can open or close the valve port 11.

The elastic member 23 is connected to the valve stem 21 and the valve core 22 respectively. When the valve core 22 closes the valve port 11, the elastic member 23 is in a compressed state and forms a pre-tightening force. At this time, the elastic member 23 has a direction toward the valve port 22. 11, so that the valve core 22 can fully close the valve port 11, avoid the gap between the valve core 22 and the valve port 11, avoid causing leakage, and improve the qualification rate of the electronically controlled valve 1

Specifically, when the valve core 22 contacts the valve seat assembly 10 to close the valve port 11 , the valve stem 21 can move toward the valve port 11 to compress the elastic member 23 to form a pre-tightening force to close the valve port 11 when the valve core 22 When the valve core 22 is closed, the elastic member 23 exerts a force toward the valve port 11, so that the valve core 22 can fully close the valve port 11, thereby avoiding a gap between the valve core 22 and the valve port 11, and preventing liquid leakage. It is convenient to improve the qualification rate of the electronically controlled valve 1.

In some embodiments, when the driving assembly 30 drives the valve stem 21 to move in the up and down direction, the valve stem 21 can drive the valve core 22 to move in the up and down direction. When the outer peripheral surface of the valve core 22 contacts and stops the valve seat assembly 10, , the valve core 22 closes the valve port 11, and the valve stem 21 can continue to move downward but will not drive the valve core 22 to move downward. At this time, the valve stem 21 compresses the elastic member 23, so that the elastic member 23 forms a pre-tightening force. Furthermore, the elastic member 23 exerts a pre-tightening force on the valve core 22 so that the valve core 22 can fully close the valve port 11 to avoid liquid leakage.

Specifically, after the elastic member 23 is compressed, the elastic member 23 exerts a downward force on the valve core 22 so that the outer peripheral surface of the lower end of the valve core 22 is in close contact with the valve seat assembly 10 to achieve the valve opening 11 Fully sealed to avoid gaps between the valve core 22 and the valve port 11, avoid liquid leakage, and improve the qualification rate of the electronic control valve 1.

In some optional embodiments of the present invention, as shown in Figure 2, the valve core 22 is provided with an accommodating cavity 221, the elastic member 23 is provided in the accommodating cavity 221, the valve stem 21 extends into the accommodating cavity 221, and the elastic member 23 extends into the accommodating cavity 221. The member 23 stops against the valve stem 21 and the inner bottom wall of the accommodating cavity 221. When the valve stem 21 drives the valve core 22 to move and closes the valve port 11, the valve stem 21 can still move in the direction of the valve port 11 in the accommodating cavity 221. Move so that the lower end of the valve stem 21 can compress the elastic member 23 in the accommodation cavity 221 and form a pre-tightening force on the elastic member 23. At this time, the elastic member 23 has an acting force on the valve core 22 toward the valve port 11, This enables the valve core 22 to fully close the valve port 11 to avoid leakage of the electronically controlled valve 1 .

In some specific embodiments of the present invention, an end of the accommodation cavity 221 facing the valve stem 21 is provided with a pressure sleeve, and the end of the valve stem 21 that extends into the accommodation cavity 221 is adapted to stop against the pressure sleeve to prevent the valve from opening. When the end of the rod 21 stops against the pressure sleeve, the valve rod 21 can push the valve core 22 to move, and at the same time, the pressure sleeve can limit the movement range of the valve rod 21 in the accommodation cavity 221 to prevent the valve rod 21 from causing damage to the elastic member 23. Excessive compression may cause the elastic member 23 to fail.

In some embodiments, the valve stem 21 can move in the up and down direction, and the pressure sleeve is located below the valve stem 21. When the lower end of the valve stem 21 and the pressure sleeve fit, the elastic member 23 is compressed and has a force on the valve core 22. At this time, the lower end of the valve stem 21 cannot continue to move in the accommodating cavity 221 due to the force acting toward the valve port 11, so it cannot continue to compress the elastic member 23 in the accommodating cavity 221, so as to control the compression of the elastic member 23. The amount of compression, thereby controlling the size of the pre-tightening force on the elastic member 23, prevents the elastic member 23 from exerting an excessive downward force on the valve core 22 and causing the valve core 22 to be stuck at the valve port 11.

In some specific embodiments of the present invention, as shown in Figure 3, the valve seat assembly 10 includes a valve seat body 101 and a sleeve 102. The sleeve 102 is detachably provided on the valve seat body 101. The valve seat body 101 defines Out of the valve port 11, the valve needle assembly 20 and the driving assembly 30 are arranged in the sleeve 102, and the coil assembly 40 is sleeved on the outside of the sleeve 102. When the valve seat assembly 10 and the coil assembly 40 are installed together, the sleeve can be first The pipe 102 is installed on the valve seat body 101 in the up and down direction. First, fix the fixing part 80 on the lower end of the coil assembly 40, and then move the coil assembly 40 and the fixing part 80 in the up and down direction to make the fixing part 80 snap-fit with the valve seat body 101. , so that the seal 70 stops against the coil assembly 40 and the sleeve 102 in the up and down direction.

When the coil assembly 40 is placed outside the sleeve 102, the sleeve 102 can limit the position of the coil assembly 40 in the horizontal direction, and then the fixing member 80 snap-fits with the valve seat body 101 to secure the coil. The position of the component 40 along the up and down direction is limited, thereby stably fixing the coil component 40 with the valve seat component 10 and preventing the coil component 40 from falling off the valve seat component 10 .

In some embodiments, the electronically controlled valve 1 further includes a fixing part 80 , the fixing part 80 is sleeved on the sleeve 102 , the fixing part 80 is fixed to the coil assembly 40 , and the fixing part 80 is fixed to the valve seat body 101 , so that the fixing part 80 is used to The coil assembly 40 and the valve seat body 101 are stably fixed together to prevent the coil assembly 40 from falling off the valve seat body 101 when the electronically controlled valve 1 moves or vibrates, thereby enabling the coil assembly 40 to be stably connected to the driving assembly 30 The coupling cooperation allows the coil assembly 40 to stably provide driving force to the driving assembly 30, so that the driving assembly 30 can stably drive the valve needle assembly 20 to reciprocate to open or close the valve port 11.
