2. The method for using the valve with high stability for the municipal water outlet, which is applied to the method for using the valve with high stability for the municipal water outlet, is characterized by comprising the following steps of:
s1: rotating the swivel (11), the swivel (11) drives the round tube (3) to rotate, the round tube (3) moves left and right through threads, the round tube (3) drives the valve rod (4) to move left and right through the first movable rod (5), the valve rod (4) drives the stop valve clack (6) and the inserted link (7) to move left and right, and the inserted link (7) drives the check valve clack (9) to move left and right;
s2: when through flow is needed, the rotary ring (11) is rotated to adjust the circular tube (3) to the middle of the control port, so that the two valve seats (10) are simultaneously opened, the circular tube (3) is controlled to move rightwards when the valve is needed to be closed, the stop valve clack (6) is driven to block the valve seat (10) on the right side, and when water flow backflow is needed to be prevented, the circular tube (3) is controlled to move leftwards, and the check valve clack (9) is driven to block the valve seat (10) on the left side;
s3: when the temperature rises, the temperature sensing agent expands to push the push plate (38) to move rightwards, the push plate (38) drives the connecting block (41) to move rightwards through the cross rod (39) to trigger the air pump switch (43) and the forward switch (44), so that the air pump (24) and the servo motor (17) are started, the air pump (24) extracts cold air from the cold air storage tank (20) through the connecting pipe (42), and then the cold air is sprayed out through the air pipe (21) and the air spraying head (22) to cool the valve body (1);
s4: the servo motor (17) drives the threaded rod (32) to rotate through a motor shaft, the threaded rod (32) drives the positive and negative thread sleeve (33) to move inwards through threads, the positive and negative thread sleeve (33) drives the adjacent connecting rods (18) to move inwards, and the two connecting rods (18) drive the adjacent clamping plates (19) to move inwards, so that the valve body (1) is clamped;
s5: when the valve body (1) bursts due to over-high thermal expansion and cold contraction, water in the valve body (1) can leak, but the water can be blocked by the clamping plates (19), the sealing gaskets (30) at the two sides prevent the water from leaking, so that the water flow can normally circulate after the valve body (1) bursts, meanwhile, the leaked water can squeeze the movable plate (25), the movable plate (25) moves backwards to drive the movable block (27) to move backwards, the movable block (27) triggers the alarm (23) to switch, and the alarm (23) operates to alarm to remind workers to process as soon as possible;
s6: when the temperature is reduced, the temperature sensing agent contracts, the second reset spring (40) contracts to drive the connecting block (41) to move leftwards, the connecting block (41) triggers the reversing switch (46) through the connecting rod (45), so that the air pump switch (43) is closed, the air pump (24) stops working, the servo motor (17) drives the threaded rod (32) to reverse through the motor shaft, and the two clamping plates (19) leave the valve body (1) and are not clamped.
