Abstract
The utility model aims at providing a manual ratio overflow valve, which comprises a valve body and a regulating stem, wherein the regulating stem is contacted with a cam which is movably connected with the valve body, the cam is fixedly connected with a handle, and the upper portion of the handle can be fixed on different positions of an indicating strip through a locking device. The manual ratio overflow valve adopts manual mechanical control and does not generate electric spark in the working process, the manual ratio overflow valve is safe and reliable, the structure is simple, the manufacture cost is low, and the manual ratio overflow valve can be widely used in the industries such as mine exploitation, hoisting transportation, construction machinery and the like.
Description
Technical field
The utility model relates to a kind of relief valve, specifically relates to a kind of manual proportional pressure control valve.
Background technique
At present, the proportional control technology maturation in the oilhydraulic engineering generally adopts electronic ratio regulation technology, owing to use Electromagnetic Control in this technology, easily produce electrical spark in the operating process, at mining, especially in containing the colliery of inflammable gas, use, can bring hidden danger to safety in production.
Summary of the invention
In order to address the above problem, the utility model aims to provide a kind of electronic control of not using, and adopts the manual proportional pressure control valve of armstrong's patent control.
The technical solution adopted in the utility model is: a kind of manual proportional pressure control valve, comprise valve body and pressure regulation bar, and the pressure regulation bar contacts the fixedly connected handle of cam with cam on being movably connected in valve body.
The top of above-mentioned handle can be fixed on the diverse location of bar by locking device.
Can drive cam rotation by Joystick, make the indentation or stretch out under action of cam of the pressure regulation bar of contact with it, proportional pressure control valve is realized the pressure regulation action, the variation that is in proportion of the actuating quantity of its pressure parameter and handle.
The beneficial effect that the utility model produces has: 1, adopt armstrong's patent control, do not produce electrical spark in the working procedure, overcome potential safety hazard; 2, simple in structure, safe and reliable, low cost of manufacture.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below, in conjunction with the accompanying drawings the body model utility is described further
Fig. 1 shows a kind of manual proportional pressure control valve, comprise valve body 1 and pressure regulation bar 2, pressure regulation bar 2 contacts with cam 3 on being movably connected in valve body 1, cam 3 fixedly connected handles 4, Joystick 4 rotates cam 3, pressure regulation bar 2 is realized the pressure regulation action of proportional pressure control valve with regard to extended or withdrawal, and its force value is along with the variation that is in proportion of handle 4 actuating quantities; Handle 4 tops can be fixed on the diverse location of bar 6 by locking device 5, are convenient to proportional pressure control valve and are stabilized in a certain working state, and intuitively show on bar 6.
