[0016] The utility model is further illustrated by the mode of embodiment below, but it is not therefore limited in the embodiment range of the utility model.

[0017] Example 1

[0018] As Figs. 1-3 Shown, the utility model provides a kind of explosion-proof valve group for oil cylinder oil inlet pipeline.Explosion-proof valve group includes the valve body 1 of rectangular body, and explosion-proof valve 2 is installed on the front side of valve body 1, and the upper side of valve body 1 is equipped with oil source port 3 and first pressure measuring port 4, and the lower side of valve body 1 is equipped with execution mechanism interface 5, and the left side of valve body 1 is equipped with second pressure measuring port 6;

[0019] Explosion-proof valve 2 includes oil inlet 21 and oil outlet 22, and oil inlet 21 is connected with oil source port 3, and oil outlet 22 is connected with execution mechanism interface 5;Execution mechanism interface 5 connects oil cylinder.

[0020] First pressure measuring port 4 is connected between oil source port 3 and oil inlet 21, and first pressure measuring port 4 is connected with first pressure gauge;Second pressure measuring port 6 is connected between oil outlet 22 and execution mechanism interface 5, and second pressure measuring port 6 is connected with second pressure gauge.

[0021] The upper side of the valve body 1 is further provided with several bottom holes 7 and mounting holes 8, the bottom holes 7 are four connecting holes distributed around the oil source port 3; the mounting holes 8 are four through holes distributed around the first pressure measuring port 4.

[0022] The explosion-proof valve 2 is a plug-in valve, and the valve body 1 is made of alloy steel.

[0023] The working principle of the utility model is: hydraulic oil enters from the oil source port 3, passes through the explosion-proof valve 2 to the actuator interface 5 and enters the oil cylinder, so that the oil cylinder can perform lifting and other actions; at this time, the explosion-proof valve 2 is in a communication state, that is, the oil inlet 21 and the oil outlet 22 are in communication. When the oil inlet pipeline connected with the oil source port 3 suddenly bursts under certain special circumstances, the pressure at the second pressure measuring port 6 will suddenly increase, which will cause the hydraulic oil in the oil inlet pipeline to flow out; at this time, a huge pressure difference will be generated between the first pressure measuring port 4 and the second pressure measuring port 6, and the communication valve core inside the explosion-proof valve will be automatically locked in time, that is, the oil inlet 21 and the oil outlet 22 are not in communication and are in a closed state, so that the hydraulic oil does not flow out, thereby ensuring that the oil cylinder will not have a misoperation or cause a safety accident.

[0024] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that this is only an example, the protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
