Description
Technical field
The utility model relates to a kind of valve class, especially relates to a kind of safety valve.
Background technique
Safety valve is a kind of valve body that can open valve according to working pressure automatically, generally is installed in protective system safety on locking system equipment or the pipeline.When the equipment of locking system or the pressure in the pipeline surpassed specified value, safety valve was promptly opened automatically and is let out valve, and assurance equipment and pipeline internal medium try to avert accidents in the numerical value stipulating.There are a lot of problems in process of production in safety valve in the market, and such as complex structure, and cost of production is high, and high material consumption is simultaneously of low quality, has potential safety hazard, and this is in disadvantageous status on market competition!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in relevant industries for many years and practice; Design a kind of safety valve, simple and practical exquisiteness can be saved material and then reduced production costs; Also have the quality of high-quality simultaneously, safety coefficient improves, and this case produces thus.
The model utility content
The purpose of the utility model is to provide a kind of safety valve, and simple and practical exquisiteness can be saved material and then reduced production costs, and also has the quality of high-quality simultaneously, and safety coefficient improves.
To achieve these goals, the technological scheme of the utility model is following:
Safety valve comprises a valve seat, is connected the valve body that is provided with valve seat, also comprises spool, valve rod, spring, adjusting screw rod and adjustment nut; Said adjustment nut is connected setting with valve body; Said adjusting screw rod is connected setting with the adjustment nut, and said valve rod passes adjusting screw rod and is connected setting with spool, and said valve body is provided with through hole; It is characterized in that: said spool is provided with a counterbore, a pair of leg and a pair of support shoulder, and said spool is arranged on the valve seat through support shoulder and leg.
Further, the bar head of said counterbore and valve rod matches, and the uncovered angle of this counterbore is 110 °-150 °.
Further, the uncovered angle of this counterbore is 120 °;
The beneficial effect of the utility model: the spool design delicate structure in the utility model; Be arranged on the valve seat through support shoulder and leg, overall structure is simple and practical, can save material greatly compared with prior art, reduce production costs; Also have the quality of high-quality simultaneously, safety coefficient improves!
In order further to explain the technological scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
