[0022] The embodiment of the utility model provides a glue valve for controlling viscous glue.
[0023] See also Figure 1-Figure 4 , including a rubber valve part 1. The setting of the rubber valve part 1 can effectively provide an effective support point for other components, thereby ensuring the smooth operation of the rubber valve. The other side of the rubber valve part 1 is fixedly connected to one side of the protective shell 12. The setting of the protective shell 12 can effectively limit other components, thereby fixing other components.
[0024] A rubber head part 9 is provided inside the protective shell 12. The setting of the rubber head part 9 facilitates the installation and disassembly of subsequent parts and makes the rubber valve more flexible. A connector part 10 is clamped on one side of the rubber head part 9. The setting of the connector part 10 can accurately fix other parts. A stainless steel rubber head 11 is inserted in the middle of the connector part 10. The setting of the stainless steel rubber head 11 avoids residual viscous glue and facilitates the outflow of viscous glue.
[0025] One side of the inner wall of the rubber head part 9 contacts the third O-ring 15 of the groove on one side of the valve core part 6. The setting of the third O-ring 15 can avoid collision between the components during assembly. One side of the rubber valve part 1 is fixedly connected to one side of the cylinder fixing seat 8. The setting of the cylinder fixing seat 8 can effectively install subsequent components. The other side of the cylinder fixing seat 8 is fixedly connected to one side of the one-way cylinder 2. The one-way cylinder 2 is a prior art and will not be described in detail. The setting of the one-way cylinder 2 can effectively provide sufficient power for the movement of subsequent components.
[0026] One end of the one-way cylinder 2 is fixedly connected to one end of the needle valve stem 7. The setting of the needle valve stem 7 can effectively control the switch of the viscous glue. The outer circumferential surface of the needle valve stem 7 contacts the middle part of the polytetrafluoro pad 5. The polytetrafluoro pad 5 is a prior art and will not be described in detail. One side of the polytetrafluoro pad 5 is fixedly connected to one side of the sealing ring 4. There are three groups of sealing rings 4. The inner walls of the three groups of sealing rings 4 are in contact with the outer circumferential surface of the needle valve stem 7. The outer circumferential surfaces of the three groups of sealing rings 4 are in contact with the inner wall of the valve part 3. The purpose of setting multiple groups of sealing rings 4 is to effectively ensure the smooth movement of the needle valve stem 7 and effectively intercept the viscous glue.
[0027] The outer circumferential surface of the sealing ring 4 contacts the inner wall of the valve part 3. The setting of the valve part 3 can effectively achieve the effect of quick installation. The outer wall of the valve part 3 is sleeved with a first O-ring 13. The outer circumferential surface of the first O-ring 13 contacts the inner wall of the rubber valve part 1. The setting of the first O-ring 13 strengthens the connection between the components and is not prone to the problem of detachment between the components.
[0028] The outer circumferential surface of the needle valve stem 7 is inserted into the groove in the middle of the valve core part 6, and the outer circumferential surface of the valve core part 6 is inserted into the groove on one side of the rubber valve part 1. The outer circumferential surface of the valve core part 6 is sleeved with a second O-ring 14. The arrangement of the second O-ring 14 makes the connection between the components tighter. The outer circumferential surface of the second O-ring 14 contacts the inner wall of the groove on one side of the rubber valve part 1, and one side of the valve core part 6 is connected to one end of the joint part 10.
[0029] Working principle: first, put the sealing ring 4 and the polytetrafluoroethylene pad 5 into the valve part 3, and press the valve part 3 into the glue valve part 1 by external force. Under the action of the first O-ring 13, the connection relationship between the glue valve part 1 and the valve part 3 is strengthened. At the same time, press the valve core part 6 into the glue valve part 1, and under the action of the glue head part 9 and the second O-ring 14, the connection relationship between the valve core part 6 and the glue valve part 1 is strengthened. The connector part 10 with the stainless steel glue head 11 is inserted into the glue head part 9 by external force again, and then the needle valve stem 7 on one side of the one-way cylinder 2 is inserted into the glue valve part 1, which is located among the valve parts 3, the sealing ring 4, and the polytetrafluoroethylene pad 5, thereby completing the rapid assembly. Finally, the viscous glue enters the glue valve from the glue inlet, and the one-way cylinder 2 is started to work, driving the needle valve stem 7 to move, thereby effectively controlling the switch of the viscous glue to achieve the expected flow rate and make it more sensitive to control.
