The following detailed description is made with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an emergency shut-off valve for a liquefied gas transportation vehicle according to an embodiment of the present invention.

As shown in figure 1, the liquefied gas transportation vehicle emergency cut-off valve comprises a transportation vehicle tank body 1 and an emergency cut-off valve body 2, wherein the transportation vehicle tank body 1 is of a hollow structure, a limiting through hole 3 is formed in one side of the transportation vehicle tank body 1, the emergency cut-off valve body 2 is slidably mounted in the limiting through hole 3, and one end of the emergency cut-off valve body 2 extends to the outer side of the transportation vehicle tank body 1.

In this embodiment, the top and the bottom of the end of the quick emergency valve body 2 extending to the outside of the transport vehicle tank 1 are symmetrically provided with L-shaped fixing rods 4, each fixing rod 4 comprises a vertical section and a horizontal section which are perpendicular to each other and are fixedly connected integrally, one end of the vertical section of each fixing rod 4, which is far away from the horizontal section, is fixedly connected with the quick emergency valve body 2, and the fixing rods are perpendicular to the quick emergency valve body 2. The horizontal section of the fixed rod 4 is parallel to the emergency cut-off valve body 2 and extends towards the tank body 1 of the transport vehicle. Furthermore, the free end of the fixing rod 4 is set to be spherical, that is, the end of the horizontal section of the fixing rod 4 extending towards the tank body 1 of the transport vehicle is set to be spherical.

Please refer to fig. 2 and fig. 3, the transportation vehicle tank 1 is provided with a limiting slot 5 above and below the limiting through hole 3, the limiting slot 5 is used to be connected with the free end of the fixing rod 4, i.e. connected with the end of the horizontal section of the fixing rod 4 extending towards the transportation vehicle tank 1. The sliding groove 6 has been seted up respectively on the one side inner wall that two spacing draw-in grooves 5 kept away from each other, and slidable mounting has slide bar 7 in the sliding groove 6, and compression spring 8 and the inside fixed connection of sliding groove 6 are passed through to the one end of slide bar 7, and the other end sets up to the sphere.

Specifically, one end of the compression spring 8 is fixedly connected with the innermost part of the sliding groove 6, and the other end is fixedly connected with one end of the sliding rod 7 extending into the sliding groove 6. Under the action of the compression spring 8, one end of the sliding rod 7, which is spherical, extends out of the sliding groove 6 and is positioned in the limiting clamping groove 5. In addition, a clamping groove 9 is formed in the fixed rod 4, and the clamping groove 9 is specifically formed in the horizontal section of the fixed rod 4 and used for being clamped with one spherical end of the sliding rod 7. During setting, the limiting clamping groove 5 is parallel to the limiting through hole 3, and the clamping groove 9 and the sliding groove 6 are perpendicular to the limiting clamping groove 5.

In this embodiment, quick action emergency valve body 2 slidable mounting in the spacing through-hole 3 on transport vehicle jar body 1 in this application, the horizontal segment level of dead lever 4 inserts in spacing draw-in groove 5, the tip that sets up to spherical on the horizontal segment of dead lever 4 can set up to the tip that spherical with slide bar 7 and contact for spherical, because two tip that contact all set up to spherical, can make the horizontal segment of dead lever 4 insert smoothly in spacing draw-in groove 5, simultaneously, two tip that all set up to spherical contact can make slide bar 7 longitudinal sliding in slide groove 6, compression spring 8 presents the state of compressed. Along with constantly inserting of the horizontal segment of dead lever 4, joint groove 9 on the horizontal segment of dead lever 4 can align with sliding tray 6 on the 5 inner walls of spacing draw-in groove, when joint groove 9 and sliding tray 6 align, under compression spring 8's effect, slide bar 7 produces the longitudinal sliding opposite before in sliding tray 6, slide bar 7 sets up the tip card that sets up to the spherical shape in joint groove 9, thereby fix on transport vehicle jar body 1 with quick action emergency valve body 2 is very firm, when having prevented the collision accident, quick action emergency valve body 2 that receives strong impact force can break or open by accident, quick action emergency valve body 1 safety intensity has been strengthened, people's demand has been satisfied, simultaneously this application is compared with prior art, the structure is simpler, more convenient and fast when installing quick action emergency valve body 1 to transport vehicle jar body 1.

Furthermore, set up the open slot 10 with the intercommunication of sliding tray 6 on the transport vechicle jar body 1 to set up catch bar 11 on slide bar 7,

catch bar

11 and 7 looks vertically fixed connection of slide bar, and outside the open slot 10 was extended to catch bar 11 one end, can drive slide bar 7 through catch bar 11 and vertically slide in sliding tray 6, thereby be convenient for lift off emergency cut-off valve body 1 from the transport vechicle jar body 1. Preferably, the pushing rod 11 can be a telescopic rod, so that the length of the pushing rod 11 can be prolonged during use, and the operation is convenient.

The application principle is as follows: when the emergency cut-off valve body 2 is installed, the emergency cut-off valve body 2 is slidably installed in the limiting through hole 3 on the transport vehicle tank body 1, the horizontal section of the fixed rod 4 fixedly connected with the emergency cut-off valve body 2 can be horizontally inserted into the limiting clamping groove 5, the end part of the horizontal section of the fixed rod 4 which is arranged in a spherical shape can be contacted with the end part of the sliding rod 7 which is arranged in a spherical shape, not only can the horizontal section of the fixed rod 4 be smoothly inserted into the limiting clamping groove 5, but also the sliding rod 7 can longitudinally slide in the sliding groove 6 when the horizontal section of the fixed rod 4 is contacted with the limiting clamping groove 5, the compression spring 8 is in a compressed state, along with the continuous insertion of the horizontal section of the fixed rod 4, the clamping groove 9 on the horizontal section of the fixed rod 4 can be aligned with the sliding groove 6 on the inner wall of the limiting clamping groove 5, when the clamping groove 9 is aligned, the sliding rod 7 is arranged in a manner that the end part of the spherical shape is clamped in the clamping groove 9, so that the emergency cut-off valve body 2 is firmly fixed on the transport vehicle tank body 1, the emergency cut-off valve body 2 which is subjected to strong impact force can be prevented from being broken or accidentally opened in the event of a collision accident, the safety strength of the emergency cut-off valve body 1 is enhanced, and the requirements of people are met; when needing to dismantle emergency cut-off valve body 2 and overhaul, only need promote catch bar 11 with 7 fixed connection of slide bar to make 7 production longitudinal sliding of slide bar and with break away from joint groove 9, just so can lift emergency cut-off valve body 1 off from the transport vehicle jar body 1, for easy operation, set up catch bar 11 into the telescopic link, can prolong the length of catch bar 11 when the operation like this, conveniently operate.
