Abstract
The utility model relates to an opening and closing angle display device for a valve, which comprises a valve body, a valve seat, a valve plate, a valve rod and flange plates, wherein the flange plates are symmetrically arranged at two sides of the outer wall of the valve body; a strengthening rib is arranged on the valve body between the flange plates; the valve rod is radially arranged inside the valve body; the valve seat is embedded and sealed inside the valve body coaxially; the valve plate is fixedly arranged on the valve rod inside the valve seat; the valve plate swings and turns under the torsion effect of the valve rod to control the valve to be opened and closed; a control handle is arranged at the upper end of the valve rod extending out of the valve body; the upper end surface of the valve rod is a round rectangle and is flush with the upper end surface of the control handle; and the direction of the long edge of the round rectangle at the upper end of the valve rod is the same as that of the valve plate at the lower part of the valve rod. The opening and closing angle display device for the valve is simple in structure; the valve rod end part structure is adopted for replacing sign arrows, the device is not likely to be damaged; as the valve rod has an integrated structure, the swing and turn angles can be ensured to be shown more accurately, the structure parts are simplified, and the mounting steps are simplified.
Description
Technical field
The utility model belongs to valve field, especially a kind of valve switch angle display device.
Background technique
Use at engineering pipeline transportation art valve is very extensive, the basic structure of valve is co-axial seal setting-in valve seat in valve body now, valve rod is radially installed on valve body, on valve rod in valve body, be fixedly mounted with valve plate, valve plate coordinates with valve base sealing, thereby valve plate rotation or movement under the driving of valve rod open and close the runner in valve seat; Valve body is shaped with the flange plate being connected with pipeline outward.
In actual use, the keying of valve and the degree of unlatching all need according to actual demand, to regulate very much, for the ease of operator, observe the open/close states of valve, the mode adopting is at present that the valve rod periphery outside valve body is installed dial, the sign arrow that is used to indicate angle is installed on valve rod, cause the accessory of valve more, install loaded down with trivial detailsly, and sign arrow and dial easily damage, and working life is shorter.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of valve switch angle display device of reasonable in design, simple in structure, easy to operate, long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A valve switch angle display device, comprises valve body, valve seat, valve plate, valve rod and flanged plate, and in valve outer wall both sides, equal symmetry is shaped with flanged plate, on the valve body between flanged plate, is shaped with stiffening rib; Valve block internal diameter is to valve rod is installed, co-axial seal setting-in valve seat in valve body, on valve rod in valve seat, be fixed with valve plate, it is characterized in that: the valve rod upper end outside stretching out valve body is provided with a Joystick, valve rod upper-end surface is made as the long rectangle of fillet and flushes with Joystick upper-end surface, and the long limit of the long rectangle of fillet of valve rod upper end is identical with the valve plate direction that is packed in stem lower portion.
And, on the valve body between described Joystick and valve body, being fixed with a lock collar 5, this lock collar one interval, side outer is shaped with two catch, and on the lock collar outer between these two catch, uniform interval is shaped with a plurality of draw-in grooves, and handle is rotation within the scope of draw-in groove.
And, a plurality of gears of the corresponding valve in a plurality of draw-in grooves position of described lock collar, handle, at its lower end is hinged with a spring sheet, and the position of the corresponding draw-in groove in this spring sheet lower end is shaped with a projection.
Advantage of the present utility model and good effect are:
1, the utility model is simple in structure, adopts valve rod end construction to replace sign arrow, not fragile, and the integrative-structure of valve rod own can guarantee to indicate rotation angle more accurate, and simplified structure accessory, simplifies installation steps.
2, the default closure of lock collar of the present utility model, small flow, intermediate flow and completely a plurality of gears such as unlatching, and handle position correspondence corresponding to gear made to draw-in groove in lock collar, standard more when operator operate, is convenient to accurately manage the flow situation of pipeline.
3, valve rod of the present utility model coordinates with lock collar, simple in structure, easily controls, and helps operator to be more prone to grasp flow situation, and simple in structure, and the installation of valve part is simple, long service life.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A valve switch angle display device, comprises valve body 8, valve seat 12, valve plate 11, valve rod 4 and flanged plate 9, and in valve outer wall both sides, equal symmetry is shaped with flanged plate, is shaped with stiffening rib 10 on the valve body between flanged plate; Valve block internal diameter is to valve rod is installed, and co-axial seal setting-in valve seat in valve body, is fixed with valve plate on the valve rod in valve seat, thus the keying of this valve plate rotation control valve under the twisting force of valve rod.
Innovative point of the present utility model is:
Valve rod upper end outside stretching out valve body is provided with a Joystick 1, valve rod upper-end surface is made as the long rectangle of fillet and flushes with Joystick upper-end surface, the long limit of the long rectangle of fillet of valve rod upper end is identical with the valve plate direction that is packed in stem lower portion, and valve rod itself replaces sign arrow indication valve opening state.
On valve body between Joystick and valve body, be fixed with a lock collar 5, this lock collar one interval, side outer is shaped with two catch 3, and on the lock collar outer between these two catch, uniform interval is shaped with a plurality of draw-in grooves 2, and handle is rotation within the scope of draw-in groove.
Opening state for accurate control valve, several gears of the corresponding valve in a plurality of draw-in grooves position of described lock collar, handle, at its lower end is hinged with a spring sheet 6, the position of the corresponding draw-in groove in this spring sheet lower end is shaped with a projection 7, this projection is installed in draw-in groove angle that can locking handle, thereby need to first compress spring sheet during adjusting, make projection depart from draw-in groove, thus then the opening degree of handle with sleeve regulating valve.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
