[0002] During the operation of a natural gas sand removal, dehydration, dehydrocarbonation and metering device, the ground safety valve plays a crucial role. However, traditional ground safety valves often have some problems. On the one hand, during the working process, the shapes of most safety valves are irregular, so the weight distribution is uneven, which easily leads to shaking and instability, affecting their normal operation and safety. On the other hand, the movement of the valve stem lacks precise guidance. If the installation is unstable, it is easy to cause inaccurate actions, making it difficult to respond to emergencies in a timely and effective manner.

[0003] By setting the support device and the connection device to cooperate with each other, the utility model balances the weight distribution of the safety valve and improves the working stability of the safety valve. At the same time, the positioning sleeve and the positioning hole in the locking device can precisely guide the movement of the valve stem, ensuring the quick response and accurate action of the position of the safety valve stem.

[0019] Working principle:

[0020] When in use, the inner wall of the valve seat 11 in the safety valve body 1 provides a sliding space for the valve stem 12, and in the use state, the valve stem 12 ensures the blocking of gas inside. The safety valve body 1 provides a foundation for installation and support for other components through the square tube 21 of the support device 2. The cross bracket 23 and the support frame 24 enhance the stability of the structure. The connecting ring 25 is convenient for connection and sliding cooperation with the connecting pipe 13 of the safety valve body 1. When the connecting ring 25 is fixed to each other by bolts and the support frame 24, the position of the connecting pipe 13 is fixed by the clamping force, thereby fixing the position of the safety valve body 1;

[0021] At this time, the connecting device 3 and the supporting device 2 are arranged to cooperate with each other so that the position of the supporting device 2 is more stable while ensuring the fixation of the position of the safety valve body 1. The counterweight block 31 is slidably connected to the outer wall of the square tube 21 through the limit groove 32. Two counterweight blocks 31 are arranged to be pushed to the two ends of the square tube 21 until the position of the limit groove 32 and the position of the connecting groove 22 contact each other and then stop, which plays a role in balancing the ground of the supporting device 2 and stabilizing the position of the supporting device 2, further improving the stability of the supporting device 2. The supporting device 2 has a simple structure and high strength, and can stably support the safety valve body 1. The cross bracket 23 and the support frame 24 increase the overall stability and prevent shaking during operation. In addition, the use of the counterweight block 31 of the connecting device 3 helps to balance the weight distribution of the safety valve and improve its working stability.

[0022] The fixing bracket 41 in the locking device 4 ensures the integrity and stability of the structure through the cooperation of the connecting block 42, the anti-disengagement block 43 and the counterweight block 31. During the process of the connecting block 42 entering the slot 33 by means of insertion, the bottom of the fixing bracket 41 is synchronously inserted into the positioning cylinder 34. The positioning hole 45 on the fixing plate 44 at the top of the fixing bracket 41 and the positioning sleeve 47 at the bottom of the extension rod 46 are both slidably connected to the outer wall of the valve stem 12, thereby playing a role in guiding and positioning the movement of the valve stem 12. When the safety valve body 1 needs to act, the valve stem 12 moves under the action of external factors. The positioning sleeve 47 and the positioning hole 45 ensure the accurate and reliable movement of the valve stem 12. The locking device 4 can accurately guide the movement of the valve stem 12 through the positioning sleeve 47 and the positioning hole 45, ensuring the quick response and accurate action of the position of the safety valve stem 12.
