Abstract
The utility model discloses a spring safety valve. The spring safety valve comprises a valve cover, a spring, a valve body, a valve core and a valve seat. The upper end portion of the valve seat is integrally connected with the valve body, the valve cover is installed at the upper end of the valve body through a lock nut, the valve core is arranged inside the valve body and arranged above the valve seat, a spring gasket and a valve core gland are sequentially installed between the valve core and the valve seat, the valve core penetrates through the spring gasket and the valve core gland through screws to be fixedly connected with the valve seat, the spring is arranged between the valve core and the valve cover, and copper screws are installed on the upper portion of the valve body. A plurality of through holes are formed in the valve body. The spring safety valve has the following advantages that the structural design is reasonable; the spring safety valve is firm and durable, the spring gasket, a sealing ring and the valve core gland are sequentially installed between the valve seat and the valve core, so that the sealing performance is high; air leakage before the opening pressure is achieved is effectively prevented, so that safety is high; the spring has good elastic pressure and can have the good the pressure relief function, the surface of the spring is galvanized, and therefore the functions of attractiveness and rust prevention are achieved.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of Direct spring loaded safety valve of safe, long service life.
Background technique
Safety valve is a kind of safety protection valve; its open-shut device is subject under External Force Acting in normally off; pressure medium in equipment or pipeline raises; while surpassing specified value, automatically open; prevent that by efflux medium to system in pipeline or equipment, pressure medium surpasses specified value, personal safety and equipment have been moved to important protective action.Safety valve technique of the prior art is comparatively coarse, and spool is assemblied in valve body to move up and down and the jam phenomenon occurs, and between spool and valve seat, sealing is poor, and when reaching cracking pressure,, there is not potential safety hazard in just gas leakage of safety valve.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of reasonable in design, safe, sealing strong, the Direct spring loaded safety valve of long service life.
For achieving the above object, the technical solution of the utility model is:
A kind of Direct spring loaded safety valve, comprise valve gap, spring, valve body, spool, valve seat, described valve seat upper end portion integral type connects valve body, valve gap is installed by locking nut in the valve body upper end, valve inner is provided with spool and is placed in the valve seat top, and spring washer and spool gland are installed between spool and valve seat successively, and spool passes spring washer and spool gland and valve seat by screw and fixes, be provided with spring between spool and valve gap, brass screw is installed on valve body top.
As preferably, have several through holes on described valve body.
As preferably, the seal ring of being made by nitrile rubber is installed between described valve seat and spool.
As preferably, described valve seat outer surface is provided with screw thread.
As preferably, described both ends of the spring is also tight, and every end 3/4 circle polishes, and plating zinc on surface is processed.
The utility model compared with prior art has the following advantages: the valve seat integral valve body, valve gap is installed by locking nut in the valve body upper end, reasonable in design, durable, mounting spring packing ring, seal ring, spool gland successively between valve seat and spool, sealing is strong, effectively prevent from not leaking gas when reaching cracking pressure, safe, spring has good elastic pressure can finely play the pressure release effect, the spring plating zinc on surface is processed, and has attractive in appearance, antirust function.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
