Referring to the figure, the upper part and the lower part of the valve body structures on the two sides are respectively fixed with the valve rod sleeve through bolt fixing. When the valve body assembly is assembled, a manufacturer firstly installs the valve core of the ball valve in the ball valve installation cavity, and then fixes the valve body and the valve rod sleeve through the bolt, so that the assembly of the combined valve body is convenient, and the assembly efficiency of the whole assembly is effectively improved.

Referring to fig. 3, a gap between the valve stem installation through hole 141 and the valve stem 220 is provided with a plurality of layers of the first packing member 610. In fig. 3, two layers of the first packing member are shown, and two sides of the first packing member 610 are respectively in contact with the side surface of the valve rod 220 and the inner side wall of the valve rod installation through hole 141. The multilayer sealing packing piece effectively increases the sealing performance of the valve body device, so that inflammable gas is not easy to leak out from the gap of the valve rod.

Referring to fig. 3, a plurality of second packing elements 620 are disposed between the ball valve spool 210 and the inner wall of the ball valve installation cavity 130. In particular, the upper and lower sides of the ball valve core 210 in fig. 3 are equipped with corresponding second packing members. The outer sidewall of the second packing 620 is in contact with the surface of the ball valve spool 210 and a portion of the inner wall of the ball valve installation chamber 130, respectively. When the ball valve core in the valve body assembly is in a cut-off state, the decompression inflammable gas cannot leak out through the gaps between the ball valve core and the inner walls of the valve body and the valve rod sleeve, and the sealing performance of the valve body is further enhanced.

Referring to fig. 1 in conjunction with fig. 4, the driving connection assembly 300 includes a gear 310 and a rack 320 engaged with the gear 310. One end of the rack 320 is fixedly connected with one end of the connecting rod 330, and the other end portion of the connecting rod 330 extends into the cylinder 410 and is fixedly connected with the piston 420. When the ball valve body shown in fig. 1 is in a conducting state, the gear is located in the middle of the rack. Although not shown, when the ball valve body is in the off state, as inferred from fig. 1, the gear is located at the rightmost position of the rack, and the piston is also located at the left side of the interior of the cylinder. The gear rotates around the central axis of the valve rod all the time, the rack moves relative to the gear, the whole driving and connecting assembly is simple and reliable in structure, and the ball valve body is quickly linked to stop under the emergency pressure loss condition.

Referring to fig. 4, the driving connection assembly 300 further includes a guide groove 340, and the rack 320 is installed to be matched with the guide groove 340 such that the rack 320 slides on the guide groove 340. The connecting rod combines the rack to do rectilinear removal in the guide rail groove and is difficult to take place the skew, effectively increases whole device's reliability. Both sides of one end of the connecting rod 330, which is close to the rack 320, are provided with a limiting block 331, and both sides of the limiting block 331 are respectively matched and limited with the end of the guide rail groove 340 and the end of the air cylinder 410. The connecting rod can not be separated from the original stroke, so that the excessive rotation of the valve core of the ball valve is influenced, and the normal communication or cut-off pipeline cannot be caused.

The gas cylinder further comprises a second starting pipeline 700 communicated with the gas outlet channel 121 and the gas filling cavity in the cylinder 410, and a second control valve 710 is installed on the second starting pipeline 700. When the valve is operating normally, the first control valve 510 is closed and the second control valve 710 is opened. When the inflammable gas on one side of the gas outlet channel loses pressure, the second control valve 710 is in an open state, the gas pressure in the valve cavity is equal to the pressure of the rear pipeline, at the moment, the piston resets under the elastic force of the spring, the valve core of the ball valve is linked, and the risk that the valve body comprehensively deals with the pressure loss of the whole pipeline is further increased.

Referring to fig. 5, a piston sealing ring 421 is fitted around the body of the piston 420, and a vent hole 411 is formed in the end cap of the spring 430 corresponding to the adjacent cylinder 410. The exhaust hole can be used in cooperation with a gas detector to detect the air tightness of the cylinder and the piston.

Referring to fig. 5, a valve operation alarm 800 is installed on a side wall of the cylinder 410, an operation trigger head of the valve operation alarm 800 is disposed in an inflation cavity between the piston 420 and an end cap of the cylinder 410, and a control port of the valve operation alarm 800 is electrically connected to the operation alarm controller. When hydrogen loses pressure, the piston slides leftwards to enable the action trigger head on the action alarm to rebound and protrude, as shown in the figure, a signal of quick cut-off of the valve body is transmitted to the action alarm controller, and the controller further transmits the signal to a user side or informs an operator of dealing with the problem on site.

Referring to fig. 6, the quick-closing cutoff ball valve is applied to a scene including a quick-closing cutoff ball valve 1000, a hydrogen production plant 2000, a hydrogen storage tank 3000 and a hydrogen user 4000. Hydrogen produced by the hydrogen production equipment is stored in a hydrogen storage tank, and a pipeline behind the hydrogen storage tank is provided with a quick-closing cutoff ball valve. When the pipeline from the back of the quick-closing cutoff ball valve to a hydrogen user is collided or damaged by force inefficacy, the pressure in the pipeline is quickly reduced, the quick-closing cutoff ball valve is quickly closed by self, the hydrogen storage tank is cut off to supply hydrogen, and the hydrogen is prevented from continuously leaking to cause greater harm. The quick-closing cutoff ball valve is provided with an action alarm, when the quick-closing cutoff ball valve acts, the alarm is sent, and meanwhile, after the storage tank is closed, the valve and the user side valve further improve the safety level of the hydrogen supply side and the user side, and meanwhile, an operator is notified to deal with the problem on site.
