As shown in fig. 1, when heat is supplied, inlet water enters the valve body through the water inlet on the left side, then flows through a gap between the outer edge of the valve head and the valve body, and finally flows out of the valve body through the water outlet on the right side; as the valve head moves rightwards, the distance L between the right conical surface of the valve head and the boss is gradually reduced, namely the flow in the water outlet direction is also gradually reduced.

The valve head 4 is also formed into a conical shape just opposite to the end face of the memory metal spring 5, so that on one hand, the resistance of the valve head to hot water in the water inlet direction is reduced, and the water inlet flow is ensured, and on the other hand, the axial acting force of the water in the valve head is reduced, so that the working accuracy of the memory metal spring is ensured.

As shown in fig. 3, the holder 3 includes a connecting rod 31 for connecting the optical axis 2, the connecting rod 31 is arranged along the radial direction of the valve body 1, and the length of the connecting rod 31 is larger than the diameter of the valve head 4 and smaller than the diameter of the adjusting section 11; the tail end of the connecting rod 31 is connected with an adjusting rod 32, and the adjusting rod 32 is arranged along the axial direction of the valve body 1; an adjusting hole 7 matched with the adjusting rod 32 is formed in the end face, opposite to the adjusting section 11, of the fixed section 12, and the adjusting hole 7 is arranged along the axial direction of the valve body 1; the length of the adjustment rod 32 is greater than the depth of the adjustment hole 7 and less than the length of the adjustment segment 11.

An adjusting assembly 8 used for controlling the adjusting rod 32 to move along the adjusting hole 7 is arranged in the adjusting hole 7, an observation window 13 corresponding to the adjusting assembly 8 is arranged on the outer wall of the valve body 1, and a key hole 14 corresponding to the adjusting assembly 8 is arranged on the end face, far away from the adjusting section 11, of the fixed section 12.

along with the rise of the water temperature in the user heat supply pipeline, the temperature of a water inlet of a user is gradually raised after water is returned, when the water inlet temperature is between 20 ℃ and 40 ℃, the memory metal is gradually lengthened, the valve head is pushed to move rightwards, the water passing amount of the valve body is gradually reduced, and the water supply amount is reduced as much as possible while the normal heat supply of the user is ensured;

when the temperature of the water inlet of a user reaches 40 ℃ after water return, the memory metal spring extends to the longest state, namely the conical surface on the right side of the valve head is tightly attached to the conical surface of the boss (as shown in figure 5) under the action of the memory metal spring, the valve body is completely closed at the moment, the water flow is zero, and excessive heating is prevented;

when the valve body is completely closed, the heat supply of a user is provided by hot water in the indoor heat supply pipeline, the temperature of the hot water in the indoor heat supply pipeline of the user is gradually reduced along with the passage of time, and the temperature of the inlet water is gradually reduced after the water is returned; along with the reduction of the temperature of the inlet water, the memory metal spring can be gradually shortened, so that the valve head moves leftwards, and the valve body is gradually opened to be in a water-passing state;

for a user who is not in the middle or in a long term and does not need heating, the support can be controlled to move rightwards by a manual key as shown in fig. 6 until the conical surface on the right side of the valve head is tightly attached to the boss, the valve body is in a manual closing state at the moment, and the valve body is always in a closed state no matter how the water temperature at the water inlet end changes;

for users or some special users (such as the old and children at home with higher requirements on heat supply conditions) at the tail end of the water supply network line, as shown in fig. 7, the support is controlled to move leftwards by a manual key, the valve body is in a non-closed state at the moment, even if the water inlet temperature reaches 40 ℃, the memory metal spring is in a longest state, the valve head is not in contact with the boss at the moment, and the valve body can be ensured to be always filled with water.

In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
