The utility model discloses simple structure, control accuracy is high.

Further, valve block fixedly connected with slide, the slide with the front end telescopic link fixed connection of cylinder, the one end at the valve block is fixed to the slide, and the telescopic link of cylinder front end is fixed on the slide, and the cylinder is ventilated and is moved the telescopic link and drive the slide and make the valve block slide to realize opening or the closed function of gas pocket.

Further, a fixing plate is connected to the air valve seat, a fixing support is mounted on the fixing plate, and the air cylinder is mounted on the air valve seat through the fixing support. The fixed plate is connected in the one end of air valve seat, and two about the fixed bolster divide into, and the cylinder is installed between the two, and the slide is parallel with the air valve base with two fixed bolsters on same straight line direction, three. The slide has certain height, is convenient for with the connection installation of cylinder, and this structural design is convenient for control cylinder stroke only on the air valve seat, prevents that the stroke is too big, and the valve block has the angular deviation, saves installation space.

Furthermore, be connected with the safety cover on the air valve seat, the valve block with the slide is located in the safety cover. Prevent short fibers and impurities from entering in the spinning process and ensure the cleanness degree.

Furthermore, the one end of safety cover is seted up the confession the through-hole that the telescopic link of cylinder passed, and a through-hole has been seted up to the one end of safety cover, and the telescopic link of cylinder passes through the through-hole and stretches into in the safety cover, avoids too much to expose.

To sum up, the utility model discloses a displacement of cylinder control valve block realizes opening of valve closed, compares with prior art and has following outstanding advantage and positive effect:

1. the air cylinder is directly pushed, the time response is more sensitive, the response speed can be changed at will, and the problem that the rotating speed balance of the stepping motor is constant is solved;

2. the thrust of the cylinder is larger, the conditions that the cylinder is blocked and the valve is not closed tightly during working are avoided, and the energy consumption utilization rate is effectively improved;

3. because the cylinder is always in a pressure maintaining state, the air valve is always in a closed state, and the situation of position deviation cannot be generated;

4. the equipment mechanism is simplified, the maintenance is facilitated, and the production cost is saved;

5. the utility model discloses convenient operation, control is simple nimble, can use on multiple equipment, can improve the clean degree of complete machine after equipment structure simplifies.
