DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5As shown, an embodiment of the utility model provides a dustproof structure of a rotating assembly for a fire hydrant valve, comprising a first dust cover 1 and a second dust cover 2, wherein a third dust cover 101 and a fourth dust cover 201 are respectively integrated on the upper ends of the first dust cover 1 and the second dust cover 2, an arc-shaped connecting ring 103 is integrated on one side of the first dust cover 1 and the second dust cover 2, a top cover 3 is hingedly connected to the upper end of the third dust cover 101 through a hinge 4, a first connecting ear 105 and a second connecting ear 106 are respectively fixedly connected at the upper and lower ends of the arc-shaped connecting ring 103 located on the first dust cover 1 and the second dust cover 2, and a connecting mechanism 8 is provided on the first connecting ear 105 and the second connecting ear 106.

[0025] Furthermore, a sealing ring 301 is fixedly connected to the edge of the lower surface of the top cover 3, and the sealing ring 301 is sealed to the two third dust covers 101. A connecting piece 6 is fixedly connected to the end of the top cover 3 away from the hinge 4, and a spring piece 7 is fixedly connected to the upper end of the fourth dust cover 201. The connecting piece 6 is clamped with the spring piece 7, and two handles 5 are fixedly connected to the upper surface of the top cover 3.

[0026] In the present application, the first dust cover 1 and the second dust cover 2 are sealed and connected by a connecting mechanism 8, so that the first dust cover 1 and the second dust cover 2 are arranged on the valve of the fire hydrant, and the top cover 3 is used to seal the upper ends of the third dust cover 101 and the fourth dust cover 201. By arranging the handle 5, the connecting piece 6, and the spring piece 7, the top cover 3 can be quickly opened, and the hand wheel of the valve can be quickly operated. When opening, the two handles 5 are lifted outward to make the top cover 3 move around the hinge 4 as the center. The connecting piece 6 squeezes the spring piece 7 when moving, so that the spring piece 7 is elastically deformed until the connecting piece 6 is out of contact with the spring piece 7, so that the top cover 3 is quickly opened. When closing, the top cover 3 is pushed in the opposite direction so that the connecting piece 6 is clamped on the spring piece 7. Among them, by arranging the sealing ring 301 at the bottom of the top cover 3, the sealing between the third dust cover 101 and the fourth dust cover 201 can be improved, providing a better dustproof effect for the rotating component of the valve.

[0027] Furthermore, the lower ends of the first dust cover 1 and the second dust cover 2 are fixedly connected with the third sealing strip 107, the first sealing strip 102 is fixedly connected to one side of the third dust cover 101, the inner sides of the two arc-shaped connecting rings 103 are fixedly connected with the second sealing strip 104, the two arc-shaped connecting rings 103 are sleeved on the water outlet of the valve, the first dust cover 1 and the second dust cover 2 are sleeved on the valve body, the two third sealing strips 107 are sleeved on the water inlet of the valve, and the third dust cover 101 and the fourth dust cover 201 are sleeved on the valve rotating assembly.

[0028] In the present application, the above-mentioned technical solution can not only prevent dust from hitting the rotating assembly of the valve, but also protect the valve body of the valve, thereby preventing dust or debris from accumulating on the rotating assembly, affecting the smoothness of the valve opening and closing, and extending the service life of the valve body.

[0029] Furthermore, the connecting mechanism 8 includes a knob 801, a connecting rod 802, a block 803, a clamping block 804 and a spring 805. The two ends of the connecting rod 802 are respectively fixedly connected to the knob 801 and the block 803. The spring 805 is sleeved on the rod body of the connecting rod 802. The clamping block 804 is fixedly connected to one side of the second connecting ear 106. The connecting rod 802 movably passes through the first connecting ear 105. The two ends of the spring 805 are respectively fixedly connected to the first connecting ear 105 and the knob 801. The second connecting ear 106 is provided with a mounting hole 108. The block 803 passes through the mounting hole 108 and is clamped with the clamping block 804.

[0030] In the present application, the connecting mechanism 8 is used to connect the first dust cover 1 and the second dust cover 2. During operation, the first dust cover 1 and the second dust cover 2 are respectively mounted on both sides of the valve body, and the spring 805 is rotated to drive the block 803 to rotate synchronously, so that the position of the block 803 corresponds to the orientation of the mounting hole 108, and then the knob 801 is pushed until the block 803 passes through the mounting hole 108, and then the spring 805 is rotated in the opposite direction to make the block 803 perpendicular to the mounting hole 108 and abut against the inside of the block 804. In the process of pushing the knob 801, the spring 805 contracts. When the block 803 abuts against the block 804, the spring 805, under the action of its own elastic force, makes the block 803 abut against the second connecting ear 106, thereby improving the stability of the block 803. Through this arrangement, the convenience of installation of the dustproof structure can be improved, and the installation and disassembly of the structure can be completed without the aid of auxiliary tools, which is convenient for subsequent maintenance and cleaning.

[0031] The working principle of this utility model:

[0032] When in use, the first dust cover 1 and the second dust cover 2 are respectively mounted on both sides of the valve body, and the spring 805 is rotated to drive the block 803 to rotate synchronously, so that the position of the block 803 corresponds to the mounting hole 108, and then the knob 801 is pushed until the block 803 passes through the mounting hole 108, and then the spring 805 is rotated in the opposite direction to make the block 803 perpendicular to the mounting hole 108 and abut against the inside of the block 804. In the process of pushing the knob 801, the spring 805 contracts. When the block 803 abuts against the block 804, the spring 805, under the action of its own elastic force, makes the block 803 abut against the second connecting ear 106, and then the top cover 3 is pushed inward, so that the connecting piece 6 is engaged with the spring piece 7, and the sealing ring 301 is sealed and connected with the third dust cover 101 and the fourth dust cover 201, and the installation of the dustproof structure is completed.

By setting the handle 5 and the connecting piece 6 , spring piece 7, can facilitate the quick opening of the top cover 3, convenient and quick operation of the hand wheel of the valve, when connecting the first dust cover 1 and the second dust cover 2, by pushing the knob 801, the block 803 passes through the mounting hole 108, and then the block 803 is rotated to make it clamped in the clamping block 804, and under the elastic force of the spring 805, the block 803 presses against the second connecting ear 106 to improve the stability of the connection. Through this arrangement, the convenience of installation of the dustproof structure can be improved, and the installation and disassembly of the structure can be completed without the aid of auxiliary tools, which is convenient for later maintenance and cleaning.
