Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As shown in Figures 1 to 3, relief valve, including relief valve body 1, described relief valve body 1 is provided with water inlet 101 and outlet 102, described relief valve body 1 has also extended laterally pressure relief opening 103, being provided with the pressure release assembly for pressure release in described pressure relief opening 103, described pressure release assembly includes pressure release valve seat 8 and the constant force spring 4 being arranged in pressure release valve seat 8, and described pressure relief opening 103 is additionally provided with the knob handle 7 for being performed manually by pressure release.
In the present embodiment, described relief valve body 1 is positioned at water inlet 101 end and is provided with the external screw thread for being connected with inlet pipeline, relief valve body 1 is positioned at outlet 102 end and is provided with the female thread for being connected with outlet pipeline.
In the present embodiment, the side being positioned at constant force spring 4 in described pressure release valve seat 8 is provided with the compressing member 3 for compressing constant force spring 4, described compressing member 3 is connected on pressure release valve seat 8 by U-shaped latch 5, and the other end of described pressure release valve seat 8 and knob handle 7 are fixedly connected with.
In the present embodiment, described knob handle 7 is provided with the threaded block for being spirally connected with relief valve body 1, being arranged with the sealing gasket 6 for sealing on described threaded block, one end that described knob handle 7 is positioned at threaded block is provided with for the fitting portion connected with pressure release valve seat 8.
In the present embodiment, it is additionally provided with silicagel pad 2 in described pressure release valve seat 8, between silicagel pad 2 and compressing member 3, is additionally provided with, in pressure release valve seat 8, the stainless steel gasket 9 withstanding silicagel pad 2.
In the present embodiment, adopt constant force spring 4, whole assembling prepare after without pressure regulation, and pressure release assembly reduces to 8 from common 12, simplifies assembling process, remove pressure regulation operation, it is greatly shortened manufacturing time so that production capacity can be substantially improved, and, changing common use handle pressure release into knob pressure release, Adjustment precision is higher; The constant force spring 4(adopted is equivalent to about force value 32N during a middle spring duty), always persevering under the extruding of compressing member 3 under duty defeat tight silicagel pad 2, the lower end of constant force spring 4 is constantly in constant force state, hydraulic pressure more than spring force value with regard to pressure release, otherwise not letting out, stability is higher.
Specific implementation process: during use, current flow to relief valve body 1 from water inlet 101, and when the force value of hydraulic pressure exceedes pressure release value, silica gel is backed down, and part current flow out from pressure relief opening 103, dispersion hydraulic pressure suffered by pipeline, it is ensured that pipeline safety.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage have been further described; it is it should be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
