Abstract
The utility model relates to a constant pressure output valve, comprising a valve body, a gate, a cylinder body, a piston, a gas-pressure feedback pipe, a spring, and a spiral pressure regulating plate, wherein, the spring and output gas pressure control the movement of the piston. The movement of the piston controls the opening of the gate via a connecting rod, and thus the output pressure is regulated automatically. The constant pressure output valve changes the defect of manual regulation of the existing valves, and thus relieves the labour intensity of workers.
Description
The utility model relates to a kind of gas that is used in, and the constant voltage delivery valve of going up main device is carried in the liquid road.
We know that use now is at gas, and the valve on fluid pipeline is carried all is to adopt hand switch.Though this valve reliable in structure, easy to operate, but under some specific (special) requirements, use, just there has been its deficiency, as require constant voltage when output, deficiency shows: 1, Shu Chu pressure is subjected to the influence of incoming pressure bigger, 2, need manpower often change the base its aperture, 3, control precision not high.
The research the purpose of this utility model provides a kind of new valve.This valve has solved the existing deficiency of above-mentioned valve, has improved control accuracy.
Constant voltage output is by cylinder, piston, spring, valve body, gate, and air pressure feedback pipe and helical pressure regulator plate are formed, and during work, utilize the variation of delivery pressure, by the aperture of piston regulating gate.Work divides three processes: 1, when incoming pressure constant, when throwing pressure and equating, the interior gas of cylinder equates that with the pressure of spring to piston piston is motionless to the pressure of piston to delivery pressure with pre-, gatage is constant, delivery pressure is constant.2 reduce when incoming pressure, and delivery pressure also reduces thereupon, in the cylinder gas to the pressure of piston less than spring during to the pressure of piston, piston stroking upward, and it is up to drive gate, gatage increases, delivery pressure increases.3, increase when incoming pressure, delivery pressure also increases thereupon, in the cylinder gas to the pressure of piston greater than the pressure of spring to piston, descent of piston, and it is descending to drive gate, gatage reduces, delivery pressure reduces.More than 2,3 described processes are alternate, form reverse feedback, till delivery pressure equals preset pressure, so just realized automatic control.
Characteristics of the present utility model are simple in structure, and cost is low, do not need other (as electric power etc.) energy, save manpower, and have improved control accuracy.
Description of drawings, Fig. 1 are constant voltage delivery valve structural drawing
Wherein: 1, cylinder; 2, piston; 3, connecting rod; 4, pressure adjusting color screw; 5, helical pressure regulator plate; 6, air pressure feedback pipe; 7, input end; 9, gate; 10, valve body; 11, seal ring; 12, pressure regulator; 13, spring; 14, seal ring; 15, cylinder body.
The utility model optimum implementation is: the constant voltage delivery valve mainly is made up of valve body (10) gate (9) connecting rod (3) cylinder block (15) piston (2) spring (13) air pressure feedback pipe (6) and helical pressure regulator plate (5).Wherein, cylinder block (15) is threaded with valve body (10), spring (13) withstands piston (2), cylinder (1) communicates with output terminal (7) by air pressure feedback pipe (6), gate (9) is connected with piston by connecting rod (3), on piston (2) and the valve body (10) seal ring (11), (14) is arranged.
