[0020] An embodiment of the utility model provides a hydraulic sequence valve that is convenient for installation, as Figures 1-4 shown, including a valve body 1 and a pipe body 2. A fixed pipe 3 is installed at the right end of the valve body 1. A limit ring 4 is installed outside the fixed pipe 3 corresponding to the right end of the valve body 1. A groove is formed at the top of the pipe body 2, and a pull rod 5 is slidably inserted into the groove. The inner end of the pull rod 5 is connected with a gasket 6. One end of the gasket 6 away from the pull rod 5 is connected with a clamping block 7. A clamping groove adapted to the clamping block 7 is formed on the outer wall of the fixed pipe 3. The outer end of the pull rod 5 is connected with a pull ring 8. The pull ring 8 is located outside the pipe body 2. A spring 9 is sleeved outside the pull rod 5. The two ends of the spring 9 are respectively connected to the gasket 6 and the inner wall of the groove of the pipe body 2. A positioning block 10 is installed at the port of the pipe body 2. A positioning groove adapted to the positioning block 10 is formed on the surface of the limit ring 4. When the valve body 1 is connected, the pipe body 2 can be sleeved outside the fixed pipe 3, and the connection part can be positioned by the positioning block 10. Then, the valve body 1 and the pipe body 2 are pushed to be closely attached. At this time, the clamping block 7 in the pipe body 2 is clamped into the clamping groove of the fixed pipe 3 under the elastic force of the spring 9, so as to limit the connection between the valve body 1 and the pipe body 2. This connection method is simple, convenient and fast, and also makes the subsequent disassembly more convenient.

[0021] There are three groups of positioning blocks 10. The positioning blocks 10 are fixedly installed obliquely, and the radian of the positioning blocks 10 is the same as that of the fixed pipe 3. By setting the positioning blocks 10 to be installed obliquely, the valve body 1 can be rotated when connected, so as to insert the positioning blocks 10 into the positioning grooves of the limit ring 4. Since the positioning blocks 10 are inclined, when the valve body 1 rotates, the positioning blocks 10 will generate a pulling force on the pipe body 2, so that the connection between the pipe body 2 and the valve body 1 is more labor-saving.

[0022] The contact surface between the pipe body 2 and the fixed pipe 3 is provided with corresponding grooves, and a sealing ring 11 is placed in the grooves. By providing the sealing ring 11, the sealing ring 11 can improve the sealing performance between the fixed pipe 3 and the pipe body 2.
