Abstract
A pressure-adjustable high-safety valve with pointer for the pressure container or pipeline is composed of casing, compressed spring unit with turned screw bolt, pressure spring and sealing unit of piston. Said compressed spring unit consists of screw bolt matched with the spiral thread of central hole on top cover, handle, presssure pointer, pressing cover at lower end of screw bolt, spring in contact with said pressing cover, piston under spring, piston rod, and sealing plug.
Description
Affiliated technical field:
Band pointer adjustable pressure relief valve device of the present invention is applied to various its pressure security be had certain requirements on container or the pipeline.
Background technique:
Existing various pressure relief valve devices, because of its safety pressure pressure release value non-adjustable, thereby can't require and pressure release according to the difference of force value in container or the pipeline.When the desired pressure resistance of container or pipeline changed, the pressure resistance of safety installations can't satisfy the pressure release requirement because of non-adjustable, and container or pipeline usually are in the unsafe factor of ultrahigh pressure, and the danger that sets off an explosion easily.
Summary of the invention:
Band pointer adjustable pressure relief valve device of the present invention, the purpose of invention, be the relief valve device of various fixation pressures to be invented be adjusting device,, form by shell 13, screw mandrel rotation compression-spring device, pressure spring and piston sealing device so that adapt to the needs of various safety pressures.The object of the present invention is achieved like this: loam cake 10 center portions at safety valve are provided with the hole, screw 11 is equipped with on top, screw mandrel 1 matches with screw 11, handle 12 is equipped with in the screw mandrel upper end, and spring capping 13 is equipped with in the lower end, and loam cake 10 surfaces are provided with the pressure indicator panel, on the screw mandrel of handle 12 bottoms pointer is housed, during rotatable handle 11, the numerical value that up-down adjustment and the pointer on the screw mandrel by spring can contrast the pressure indicator panel can be determined the safe pressure resistance of safety valve.
The drawing description of drawings
Fig. 1 is the main pseudosection of band pointer adjustable pressure relief valve device of the present invention.
Fig. 2 is the plan view of band pointer adjustable pressure relief valve device of the present invention.
Most preferred embodiment:
Band pointer adjustable pressure relief valve device of the present invention is to be made of screw mandrel 1, stage clip 2, sealing plug 3, piston rod 4, piston 5, handle 6, pointer 7, filler 8, pressure indicator panel 9, loam cake 10, screw 11, gland 12, shell 13.In air pressure ingress, shell 13 bottom piston apparatus is housed, by piston 5 being housed respectively and sealing plug 3 is formed in piston rod 4 two ends.The gland that pressure spring 2 is housed in piston 5 upper ends and is equipped with screw mandrel 1 bottom 12 fastens spring, loam cake 10 centers are with holes, screw 11 is equipped with on top, and cooperatively interact with screw mandrel 1, handle 6 is equipped with in screw mandrel 1 upper end, on the screw mandrel 1 of handle 6 bottoms pointer 7 is housed, pressure indicator panel 9 is equipped with on the surface of loam cake 10, and corresponding with pointer 7.In loam cake 10 bottoms, be provided with stuffing box packing 8 in case stopping leak leaks.When needing different pressure resistances, rotatable handgrip 6 is adjusted the size of spring pressure, and can determine the numerical value of pressure by pointer and pressure indicator panel.When the pressure superpressure, sealing plug 3 can be opened voluntarily, is reduced pressure by the air outlet on top.The present invention is convenient to control needed different pressures, and safe ready can be regulated voluntarily according to the big or small needs of pressure.
Claims (2)
1, band pointer adjustable pressure relief valve device of the present invention, be by shell (13), screw mandrel rotation compression-spring device, pressure spring and piston sealing device are formed, it is characterized in that: screw mandrel rotation compression-spring device is by screw mandrel (1), the screw (11) that is equipped with loam cake (10) center hole top matches, handle (6) is equipped with in the screw mandrel upper end, on the screw mandrel of handle (6) bottom pressure pointer (7) is housed, gland (12) is equipped with in the screw mandrel bottom, contact with spring (2) top, piston (5) is equipped with in spring (2) bottom, piston rod is equipped with in piston (5) bottom, and sealing plug (3) is equipped with in the piston rod bottom.
