Although full valve is solved because of a series of not compact enough the defects brought of structure, but still suffers from some problems, such as uses adjusting ring
In regulation valve body chamber during the size of accumulation degree, adjusting ring may be too close to valve element, like that, at valve body and seal spool
Leakage this may result in valve and prematurely open suddenly, but because now pressure medium is also not enough to valve element being maintained at unlatching
Position, valve element is closed again immediately, and then chatter occurs for valve；Passage is generally straight barrel type at another existing valve seat, and medium enters valve
Resistance is larger when interior, reduces the performance of safety valve.
The content of the invention
The utility model is directed to the shortcomings of complicated in the prior art, installation is inconvenient, and there is provided a kind of simple in construction, peace
Fill convenient spring loaded safety valve.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
Provided with the valve element moved up and down in valve body in spring loaded safety valve, valve body, it is provided with and is offseted with valve element above valve element
Pressure spring, the upper surface of pressure spring is provided with annular groove, and the lower end of pressure spring, which coordinates, to be located in annular groove, valve body
Upper end be provided with the pressure regulating screw that be connected with valve body, the upper end connection of pressure regulating screw and pressure spring.By rotating pressure regulating screw
The elastic force of pressure spring is adjusted, so as to accurately control the air pressure entered, the gas leakage in not up to Opening pressure is effectively prevented, carries
High safety performance, this technology is simple in construction, easy for installation.
Preferably, pressure spring upper end is provided with the spring base that pressure spring upper end is connected, pressure regulating screw connects with spring base
Connect.By setting spring base and annular groove to fix the position of pressure spring, it is to avoid pressure spring is in the presence of pressure regulating screw
Bias, the error of build-up of pressure regulation.
Preferably, also including the valve base joint being connected with valve body, valve base joint is provided with thread segment, and valve base joint passes through
Thread segment screws in valve body lower end and is connected with valve body screw thread, and inlet channel is provided with valve base joint, and valve body is provided with gas outlet, outlet
Mouth is located at the top of valve base joint.Gas enters top valve opening core from inlet channel and enters valve body, and gas is exported from gas outlet, entered again
Row pressure release, improves security performance.
Preferably, the lower end of valve element is provided with the step section being connected with valve element, the body diameter of step section is less than valve element
Body diameter, gas outlet is located at the lower end of valve element, and the lower end of step section is provided with sealing ring, during closing, sealing ring and inlet channel
Upper end offset.Gas outlet is located between valve element and valve base joint, facilitates gas to lose heart from gas outlet, by setting sealing ring,
Improve step section and the sealing of valve base joint when closing.
The utility model is as a result of above technical scheme, with significant technique effect：By rotating pressure regulating screw
The elastic force of pressure spring is adjusted, so as to accurately control the air pressure entered, the gas leakage in not up to Opening pressure is effectively prevented, carries
High safety performance, this technology is simple in construction, easy for installation.
