The invention discloses a hydraulic valve convenient to fix. The hydraulic valve comprises a shell, a fixed sleeve and a valve; a liquid passing port is formed in the lower end of the shell; the outerside of the top end of the liquid passing port is provided with a rust-proof ring; a sound isolation layer is fixed to the outer side of the shell; the fixed sleeve is arranged at the top end of theinner side of a mounting groove; the fixed sleeve is connected with a resistance block; the lower end of the resistance block is arranged at the inner side of a folded hole; a bolt is arranged in thevertical direction of the folded hole; the valve is arranged on the shell; the lower end of the valve is fixedly provided with a clamping ring; a second protective fence and a first protective fence are connected with each other; and the top end of the second protective fence is provided with a rectangular hole and a combination strip. According to the hydraulic valve convenient to fix, rust-prooftreatment can be performed on the liquid passing port; meanwhile, the outer side of the shell is provided with a sound isolation material, so that the function of noise reduction and shock absorptionis exerted; and moreover, the valve is enclosed, so that the valve cannot rotates under the influence of an external force, and the safety during use is enhanced.
