Description
Technical field
The present invention relates to a kind of valve, more particularly to a kind of safety valve.
Background technology
Valve is widely used in petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel
Etc. industry, very important status is occupied in national economy.It has the action being rotated by 90 °, and faucet body is spheroid, there is circle
Shape through hole or passage pass through its axis.
Present valve is divided into two kinds of Bevel Gear Drive and Worm Wheel System, and the gear-box of wherein Bevel Gear Drive is complete
Revolution, but do not possess auto-lock function；And the gear-box of Worm Wheel System is then opposite, although possess self-lock ability, but only have
The function of part revolution.Under some service conditions, this gear-box can not meet use requirement.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of safety valve.
The technical solution adopted by the present invention is：
A kind of safety valve, including housing, valve element and valve seat, the valve seat are arranged on below housing, provided with activity in the housing
It is provided with cavity and fixed cavity, the activity cavity in spring, the fixed cavity and is provided with valve element, the activity cavity is located at
The lower section of fixed cavity, is provided with connecting portion, is connected between the valve element and spring by piston, institute between the valve element and spring
State and annular groove is provided with connecting portion, the annular groove is engaged to form self-locking with piston.
Further, the seat bottom portion is provided with drain tap.
Further, it is provided with hole on the valve element.
Further, the piston is in connecting portion.
Further, the connecting portion is arc-shaped.
The beneficial effects of the invention are as follows：It is simple in construction, it is easy for installation using simple operation, by piston by valve element and bullet
Movable between spring, with preferable circulation effect, range of regulation is big, and using annular groove, peace is improved with piston formation self-locking
The stability of full valve.
