Abstract
The utility model relates to a mechanical equalising valve. A digital locking equalising valve which can accurately control the pressure drop of a liquid in a pipeline system is designed, against the difficulty that the error of the pressure drop in a fluid pipeline system is difficult to eliminate in practical use. The digital locking equalising valve is composed of a valve body, valve cover, valve rod and a valve plug. A figure dial is installed on a circular base body which is on the valve cover; a digital displaying gear wheel is installed at one side of the circular base body; a locking pin is arranged at the other side of the circular base body. A flow regulating valve and a stop valve can be replaced by the digital locking equalising valve; the digital locking equalising valve has the character of automatically recording numbers; the utility model can be used in the liquid pipeline systems in civil heating, metallurgy and petrochemical industry, etc.
Description
The utility model relates to a kind of balance of machinery valve.
At present, in the liquid pipeline system of industries such as industry and civil building heating and metallurgy, petrochemical industry, valves such as the throttle valve that adopts, stop valve, as the L41H-25 of Jinzhou valve plant production, the J41H-40 product that Shenyang valve plant produces, all rule of thumb operate, therefore, make the pressure drop error that produces in the design, in actual applications, can not get compensating effectively, cause problems such as pipe-line system liquid pressure drop imbalance, energy waste are very big to be difficult to solve.
The utility model is at above-mentioned technological difficulties, for liquid pipeline system has designed a kind of number lock equilibrium valve, in operating process, can rotate handwheel according to producing needs, grasp handwheel by digital peep hole and rotate the number of turns and valve plug opening degree, regulate the pressure drop of liquid in the pipe-line system more exactly, reach energy-conservation purpose.
The utility model number lock equilibrium valve is made of valve body (1), valve gap (2), valve rod (9) and valve plug (20), it is characterized in that:
(a) justify pedestal (3) and be installed in valve gap (2) top, the dial (7) that is carved with numeral is installed on circle pedestal (3) top, dial (7) adopts taper pin (8) to be fixed on the valve rod (9), and the dial bottom is provided with the mounting hole (24) of 10 lockholes (23) and finger (12); (b) justify a side in the pedestal (3), adopt wheel shaft (17) location digital display gear (16), the digital display gear is round stepped shaft, last cylinder diameter is less than following cylinder diameter, and disk is carved with numeral on it, and the gear teeth are in last cylindrical body side, and the cylindrical body side has 10 Baltimore grooves equidistantly down, be carved with the percentage number on the surface between groove, in cylindrical body (3), spring sheet (14) be installed also; (c) justify the interior opposite side of pedestal (3), the lock pin (6) by spring (5) control is installed, the lock pin side-lower is provided with rectangle side opening (4), and fine wire axle (4 ') is installed in the lock pin side opening; (d) cylindrical body (3) has digital peep hole (13) and percentage that eyeglass is installed and counts peep hole (15); (e) justify pedestal (3) and be provided with and the corresponding keyhole of lock pin side opening (4) (22), and be furnished with oblique key; Numeral peep hole (13) and percentage are counted peep hole (15) respectively with to be carved with the percentage number on the surface between the cylindrical body groove under the numeral that is carved with of disk and the digital display gear corresponding on the digital display gear (16); Finger (12) can match with the gear teeth of digital display gear (16), and can be by the rotatory force of finger, stirring the gear teeth rotates digital display gear (16), spring sheet (14) be installed in the digital display gear under on the relevant position of cylindrical body lateral grooves, protruding part on the spring sheet can be stuck in the middle of the groove, makes digital display gear location.
The advantage of the utility model number lock equilibrium valve is: simple in structure, compact, volume is little.Digital display portion can be read three numerals simultaneously, but a gear only is installed, and leans on the rotatory force of a finger can make its rotation, and the gear location is also only with a spring sheet; Security is good, can lock by oblique key, avoids not operation personnel rotating valve, has strengthened reliability; Have numeral and show, overcome the shortcoming of operation by rule of thumb, the pressure drop in the pilot line system reaches purpose of energy saving more exactly.This valve can be adapted to the application that bore is the pipe-line system of specifications such as Dg50,65,80,100,200,300mm; Differences such as WATER AS FLOW MEDIUM, oil, acid, alkali, salt, this valve can be selected unlike material, is widely used in liquid pipeline system.
