Abstract

A temperature-sensitive regulating valve core includes a front cover, a flow-stabilizing core, a pressure spring, a balancing cover and an adjusting plate. The threaded connection part of the flow-stabilizing core is screwed into the threaded hole of the balancing cover and extends out of the balancing cover. The threaded connection part is screwed into the adjusting plate. There is a flow-guiding gap between the adjusting plate and the balancing cover, and the adjusting plate covers the flow-guiding hole. The end of the cylindrical body of the flow-stabilizing core is fixed to the guide hole. One end of the pressure spring cooperates with the bottom plate of the body of the front cover and the other end cooperates with the balancing cover. The opening end of the balancing cover extends into the body of the front cover and slides in cooperation. Due to the use of such a structure, the gap between the adjusting plate and the balancing cover can be adjusted by rotating the adjusting plate to adjust the water flow. The relative movement of the balancing cover and the front cover plays a role in stabilizing the flow.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a temperature-sensitive regulating valve core includes a front cover 1, a steady flow core 2, a pressure spring 3, a balance cover 4 and an adjusting plate 5,

The front cover 1 includes a body 11 and a head 12, one end of the body 11 is open, a guide hole 111 is arranged on the bottom plate of the body 11 to communicate with the inner cavity of the head 12, and the end plate of the head 12 has a water outlet;

One end of the balance cover 4 is open, and the cover plate has a threaded hole 41 and several diversion holes 42 arranged around the threaded hole;

The flow stabilization core 2 includes a threaded connection portion 21 and a cylinder portion 22, and the cylinder portion 22 has a radial flow stabilization hole 23;

The threaded connection part 21 of the flow stabilization core 2 is screwed with the threaded hole 41 of the balance cover 4 and extends out of the balance cover 4. The threaded connection part 21 is screwed with the adjustment plate 5. There is a diversion gap between the adjustment plate 5 and the balance cover 4. The adjustment plate 5 covers the diversion hole 42; the end of the cylinder part 22 of the steady flow core 2 is slidingly fitted with the guide hole 111, one end of the pressure spring 3 is matched with the bottom plate of the body part 11 of the front cover 1, and the other end is matched with the balance cover 4 Fitting; the opening end of the balance cover 4 extends into the body portion 12 of the front cover 1 and is slidably fitted;

The radial stabilizing hole 23 communicates the stabilizing core 2 with the volume cavity formed by the adjustment balance cover 4 and the front cover 1, and the diversion hole 42 communicates with the volume cavity;

One is that the balance cover 4 rotates relative to the steady flow core 2, while adjusting the volume cavity between the balance cover 4 and the front cover 1, the size of the diversion gap between the adjustment plate 5 and the balance 4 is adjusted;

The second is to rotate the adjustment plate 5 to adjust the size of the diversion gap between the adjustment plate and the balance cover 4, so as to adjust the size of the water flow.
