[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.

[0021] The embodiments will be described below according to the overall structure of the utility model.

[0022] A kind of butterfly valve, such as Figures 1 to 5 As shown, including butterfly valve body 100 of pair of clamps, butterfly valve body 100 is assembled with butterfly plate 101 inside, the curved surface outer wall of butterfly plate 101 is provided with blind hole 103, the lower half outer wall of butterfly valve body 100 is provided with outer U seat 110, the inner side of outer U seat 110 movably is provided with inner U seat 111, the left and right outer walls of outer U seat 110 are provided with positioning rod 130 penetrating outer U seat 110 and inner U seat 111, the end of positioning rod 130 passes through butterfly valve body 100 and extends into blind hole 103, screw cylinder 140 is fixed at the contact position of inner U seat 111 and positioning rod 130, the inner wall of screw cylinder 140 and the outer wall of positioning rod 130 are connected by screw, the transverse inner wall of inner U seat 111 is rotatably provided with two groups of cambered triangular strips 120 below butterfly valve body 100;

[0023] The curved surface outer wall of screw cylinder 140 movably is sleeved with base plate 112 outside inner U seat 111, the bottom end of base plate 112 is fixed with hard rubber strip 113 extending into outer U seat 110, and the contact position of outer U seat 110 and hard rubber strip 113 is provided with matching rectangular groove.

[0024] When the pair of clamping butterfly valve body 100 is closed, manually control two groups of positioning rod 130 to approach to the middle, so that the end part enters into blind hole 103, so that the compression resistance of the butterfly plate 101 can be improved, and the leakage caused by the rotation of the butterfly plate 101 due to water pressure can be better avoided, and the power device for controlling the butterfly plate 101 can be protected, and the service life of the pair of clamping butterfly valve body 100 can be prolonged.

[0025] When docking, two groups of cambered triangular strips 120 can be rotated around damping shaft 121 as the base point, so that the docked pipelines are located between the two groups of cambered triangular strips 120, to ensure that they will not roll, so that the worker can conveniently fix the penetrating bolt, and after fixing one end, the two groups of cambered triangular strips 120 are rotated in the other direction, so that the docking of the two pipelines can be efficiently completed.

[0026] Likewise, the outer U-shaped seat 110 can be rotated by 180 degrees along the axis of the threaded cylinder 140 to form a quadrilateral frame with the inner U-shaped seat 111, thereby protecting the body 100 of the clamping butterfly valve and preventing damage caused by external pressure during carrying, and improving the practicality of the body 100 of the clamping butterfly valve.

[0027] Please refer to Figure 4 and Figure 5 The lower surface of the arc surface triangular strip 120 is fixed with a damping shaft 121 near the end position, and the end of the damping shaft 121 extends into the inner U-shaped seat 111 and is rotatably arranged.

[0028] The damping shaft 121 increases the friction between the arc surface triangular strip 120 and the inner U-shaped seat 111, thereby preventing the arc surface triangular strip 120 from being driven to extend arbitrarily.

[0029] Please refer to Figure 1 , Figure 4 and Figure 5 The six-sided handle 131 is fixed to the end of the positioning rod 130 outside the outer U-shaped seat 110.

[0030] The six-sided handle 131 facilitates manual application of external force to the positioning rod 130 to rotate the positioning rod 130, thereby protecting the closed body 100 of the clamping butterfly valve.

[0031] Please refer to Figure 2 The curved outer wall of the body 100 of the clamping butterfly valve is sleeved with a guide cylinder 102 outside the outer wall of the positioning rod 130, and the end of the guide cylinder 102 is fixed to the curved outer wall of the body 100 of the clamping butterfly valve.

[0032] The guide cylinder 102 ensures that the end of the positioning rod 130 enters the body 100 of the clamping butterfly valve to achieve a sealing effect, thereby preventing water leakage.

[0033] Please refer to Figure 5 The curved outer wall of the threaded cylinder 140 is sleeved with a rubber ring at the contact position with the base plate 112, and the base plate 112 is provided with a matching circular channel at the contact position with the threaded cylinder 140.

[0034] The rubber ring increases the friction coefficient between the outer wall of the threaded cylinder 140 and the base plate 112, thereby ensuring the stability of the outer U-shaped seat 110 when rotated to a specified position.

[0035] When in use, when the pair of clamp type butterfly valve body 100 is closed, manually control two groups of positioning rods 130 to be close to the middle, and the end part enters into the blind hole 103, so that the pressure resistance of the butterfly plate 101 is improved, the leakage caused by the rotation of the butterfly plate 101 due to water pressure is avoided, the power device controlling the butterfly plate 101 is protected, and the service life of the pair of clamp type butterfly valve body 100 is prolonged.

[0036] When docking, the two groups of cambered triangular strips 120 can be rotated with the damping shaft 121 as the base point, so that the docked pipeline is located between the two groups of cambered triangular strips 120, and the rolling of the pipeline is ensured, so that the artificial penetration of the bolt is facilitated, after one end is docked, the two groups of cambered triangular strips 120 are rotated in the other direction, so that the docking of the two pipelines is efficiently completed.

[0037] Similarly, the outer U-shaped seat 110 can be rotated one hundred and eighty degrees with the axis of the threaded cylinder 140 as a circle, so that the outer U-shaped seat 110 and the inner U-shaped seat 111 form a four-sided frame, which protects the four sides of the pair of clamp type butterfly valve body 100, ensures that the pair of clamp type butterfly valve body 100 is not damaged by external pressure during carrying, and improves the practicability of the pair of clamp type butterfly valve body 100, and the parts not involved in the device are the same as or can be realized by the existing technology.

[0038] Although the embodiments of the utility model have been shown and described, the specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and the person skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
