BRIEF DESCRIPTION OF DRAWINGS
[0010] To more clearly illustrate the solutions in this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.
[0011] Figure 1 This is a schematic diagram of the automated CNG filling valve remote closing device of this utility model;
[0012] Figure 2 for Figure 1 A schematic diagram of the fit between the valve handle sleeve and the valve handle of the remote closing device for automated CNG filling valves;
[0013] Figure 3 for Figure 2 The diagram shows the fit between the valve handle sleeve and the valve handle; this is in exploded view mode.
[0014] Figure 4 This is a schematic diagram illustrating the use of the automated CNG filling valve remote closing device of this utility model.
[0015] The markings in the diagram are explained as follows: 1. Valve handle sleeve; 11. Square tube body; 12. Steel wire connecting lug; 13. Connecting hole; 14. Locking screw hole; 15. Locking screw; 2. Guide rail; 3. Movable bracket; 4. Bracket pulley; 5. Steel wire rope; 6. Electric actuator; 7. Remote controller; 9. Control harness. Detailed Implementation
[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0017] like Figure 1 As shown, the automated CNG filling valve remote closing device includes a horizontally arranged guide rail 2, on which a horizontally movable support 3 is provided. The top of the movable support 3 is provided with a support pulley 4, and a steel wire rope 5 is provided on the support pulley 4. One end of the steel wire rope 5 is connected to a valve handle sleeve 1, and the other end of the steel wire rope 5 is connected to an electric actuator 6. The electric actuator 6 is connected to a remote controller 7 through a control harness 9.
[0018] It should be noted that the movable bracket 3 can move left and right along the direction R on the guide rail 2 and be fixed.
[0019] like Figure 2 and Figure 3As shown, the valve handle sleeve 1 comprises a hollow square tube body 11, a steel wire connecting lug 12 is arranged on the side wall of the square tube body 11, a through connecting hole 13 is arranged on the steel wire connecting lug 12, a pair of locking screw holes 14 are arranged on the side wall of the square tube body 11, and a locking screw 15 is arranged on the locking screw hole 14.
[0020] It should be noted that the valve handle sleeve 1 is made of stainless steel.
[0021] The working mode of the automatic CNG filling valve remote closing device will be described below.
[0022] When the CNG tank car filling operation is performed, the filling valve is in an open state, at this time, the valve handle 8 of the filling valve is upward.
[0023] The user sleeves the valve handle sleeve 1 on the valve handle 8 and tightens the locking screw 15.
[0024] Then, the position of the movable support 3 is adjusted according to the position of the CNG tank car and the position of the valve handle 8, and the movable support 3 is fixed on the guide rail 2.
[0025] As shown in the figure, Figure 4 When an accident occurs during the CNG tank car filling process, the electric actuator 6 is controlled by the remote controller 7, then the electric actuator 6 pulls the steel wire rope 5, the steel wire rope 5 moves along the direction F, then the valve handle sleeve 1 drives the valve handle 8 to rotate, and the filling valve is quickly closed.
[0026] The automatic CNG filling valve remote closing device can realize remote closing of the CNG tank car filling valve, reduce the leakage of natural gas in abnormal conditions, avoid the occurrence of major safety accidents, improve the safety and reliability of the CNG filling site, and has the advantages of reliable structure and strong practicability.
