According to the adjustable pressure reducing and stabilizing valve, pressure control is stable and reliable, the pressure reducing pilot valve and the main valve work continuously, an downstream pressure is continuous and stable in change and is slightly influenced by the pressure of an inlet; operation is convenient, the main valve carries out automatic adjustment when the upstream pressure or flow changes after working pressure is set up, and the downstream pressure is stabilized; due to the fact that the full-channel, straight-flow and streamlined design is adopted by the flow channel of the main valve, hydraulic power loss is small, and the energy-saving effect is good.
Description
Technical field
The utility model relates to valve field, relates in particular to a kind of adjustable decompressing controlling valve.
Background technique
At present, generally in the upstream of tall building, life region or other water supply pipe net system, control valve is installed, to realize the pressure-reduced and-regulated function to its downstream pipe network or device.Main employing decompression venting valve in prior art, unstable but the pressure of this valve is in the market controlled, hydraulic loss is large, and energy-saving effect is not obvious.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of adjustable decompressing controlling valve.
The utility model is to be achieved through the following technical solutions:
A kind of adjustable decompressing controlling valve, comprise main valve, ball valve, pressure gauge, needle type regulating valve, decompression pilot valve, on left and right two hydraulic fluid ports of described main valve, all by conduit, connect ball valve, on ball valve, be connected with pressure gauge, detect in real time the pressure medium of the ball valve of flowing through, the left end hydraulic fluid port of described main valve is also connected with aciculiform modulating valve by conduit, and be connected on the left oil port of valve gap of main valve, the hydraulic fluid port of the right-hand member of described main valve is also connected with decompression pilot valve by conduit, and is connected on the right oil port of valve gap of corresponding main valve.
As optimal technical scheme of the present utility model, described main valve is diaphragm type main valve.
As optimal technical scheme of the present utility model, described diaphragm type main valve comprises valve body, described valve body comprises entrance point and outlet end, on described valve body, valve gap is installed, in valve pocket in valve body, valve rod is installed, on described valve rod, spring is installed, one end contact valve gap of described spring, the other end is connected on diaphragm on platen, on diaphragm, between platen and diaphragm pressing disc, diaphragm is installed, in one end of described valve rod, be connected with platen on seal ring, on seal ring, between platen and seal ring pressing disc, seal ring is installed, the upper end of described valve gap is provided with suspension ring by tightening hexagon nut.
As optimal technical scheme of the present utility model, the entrance point of described diaphragm type main valve and the runner of outlet end are direct current type runner.
Its working principle is: when conduit feeds water from feed-water end, water flows through needle type regulating valve and enters main valve control room, outlet pressure is applied on pilot valve by conduit, when outlet pressure is during higher than pilot valve setting value, pilot valve cuts out, control room stops draining, and now main valve control room internal pressure raises and closes main valve, and outlet pressure no longer raises.
When outlet pressure drops to pilot valve setting pressure, pilot valve is opened, and control room is draining downstream.Because the water displacement of pilot valve is greater than the inflow of needle type regulating valve, main valve control room pressure drop, inlet pressure is opened main valve.Under steady state, control room intakes, draining is identical, and aperture is constant, and outlet pressure is constant.
Compared with prior art, the beneficial effects of the utility model are:
1, pressure control is reliable and stable, decompression pilot valve, main valve continuous operation, and disturbances continuously, steadily, is affected by inlet pressure little.
2, easy to operate, after working pressure is set up, when upstream pressure or flow change, main valve regulates automatically, has stablized downstream pressure.
3, the runner of main valve has adopted full tunnel, direct current type, airflow design, and hydraulic loss is little, good energy-conserving effect.
