Abstract

A kind of multi-functional pilot-operated diaphragm valve, is made up of penstock, pressure release mouth, water output duct, valve gap, turriform spring, holding down bolt, diaphragm, ball float, valve body.Between valve gap and valve body, diaphragm is set, shape that diaphragm is designed to " recessed ", diaphragm is by changing nylon and ethylene-propylene diene copolymer high temperature is compressing, and the recess of diaphragm is settled upward, is provided with diaphragm pressing plate, holding down bolt, turriform spring in the recess of diaphragm, diaphragm pushed down by diaphragm pressing plate, diaphragm pressing plate fixed by holding down bolt, and turriform spring one end connects holding down bolt, and the turriform spring the other end connects valve gap, the small end head of turriform spring is installed down, forms water storage cavity between diaphragm and valve gap; Valve gap is provided with pilot valve, and pilot valve is floating ball structure, and penstock, water output duct are separately positioned on pilot valve two ends, and water output duct connects ball float, and water storage cavity is communicated with the water intake on valve body by inlet ducts.Easy to use, various control function, structure is simple.

Description

Multi-functional pilot-operated diaphragm valve
Technical field
The utility model relates to a kind of membrane valve, particularly relate to a kind of multi-functional pilot-operated diaphragm valve, have employed guide's diaphragm type design proposal, the break-make in water route is realized by the motion of barrier film, float valve regulates aperture to regulate the pressure difference of water storage cavity and water intake according to liquid level height automatically, realize the motion of septum assembly, realize multi-functional waterpower controlling functions, working stability.
Background technique:
Common hydraulic control valve door need configure the match mechanisms such as electric actuator, pressure transducer, hydraulic element, control apparatus complex structure due to electronic, hydraulic control valve, install and maintenance difficult, reliability lower, cost of use is higher.Therefore, according to the deficiency of existing hydraulic control valve and the raising of usage requirement, research and development one has waterpower concurrently and controls, reduces pressure, holds the multifunctional novel hydraulic control valve such as pressure, water hammer elimination and seem necessary.
Model utility content:
For the deficiency of existing common fluid-valve, the utility model provides a kind of multi-functional pilot-operated diaphragm valve, is made up of penstock, pressure release mouth, water output duct, valve gap, turriform spring, holding down bolt, diaphragm, ball float, valve body.
The utility model solves the technological scheme that its technical problem adopts: arrange diaphragm between valve gap and valve body, shape that diaphragm is designed to " recessed ", diaphragm is by changing nylon and ethylene-propylene diene copolymer high temperature is compressing, the recess of diaphragm is settled upward, diaphragm pressing plate is provided with in the recess of diaphragm, holding down bolt, turriform spring, diaphragm pushed down by diaphragm pressing plate, diaphragm pressing plate fixed by holding down bolt, turriform spring one end connects holding down bolt, the turriform spring the other end connects valve gap, the small end head of turriform spring is installed down, water storage cavity is formed between diaphragm and valve gap, valve gap is provided with pilot valve, and pilot valve is floating ball structure, and penstock, water output duct are separately positioned on pilot valve two ends, and water output duct connects ball float, and water storage cavity is communicated with the water intake on valve body by inlet ducts.
The beneficial effects of the utility model: easy to use, various control function, structure is simple, easy to maintenance, No leakage, corrosion-resistant, without wearing and tearing, the advantages such as distant control.
Accompanying drawing illustrates:
Fig. 1 is the utility model product structure schematic diagram;
In figure, 1, penstock, 2, pressure release mouth, 3, water output duct, 4, valve gap, 5, turriform spring, 6, holding down bolt 7, diaphragm 8, ball float 9, valve body.
Embodiment:
As shown in the figure, between valve gap and valve body, diaphragm is set, shape that diaphragm is designed to " recessed ", with high temperature press ethylene-propylene diene copolymer with change nylon and add and make diaphragm 7, the recess of diaphragm is settled upward, diaphragm pressing plate, holding down bolt, turriform spring is provided with in the recess of diaphragm, diaphragm pushed down by diaphragm pressing plate, diaphragm pressing plate fixed by holding down bolt, turriform spring one end connects holding down bolt, the turriform spring the other end connects valve gap, and the small end head of turriform spring is installed down, forms water storage cavity between diaphragm and valve gap, valve gap is provided with pilot valve, pilot valve is floating ball structure, pilot valve is by penstock, pressure release mouth, water output duct, ball float is formed, penstock, water output duct is separately positioned on pilot valve two ends, water output duct connects ball float, control the SEA LEVEL VARIATION of water storage cavity, water storage cavity is communicated with the water intake on valve body by inlet ducts, when the water level descends, ball float 8 moves downward due to buoyancy deficiency, pilot valve is opened, the pressure release mouth 2 that pilot valve carries communicates with water storage cavity, upper cavity pressure water enters water tank by pressure release mouth 2, now, the rapid drawdown of valve upper cavity pressure, under the effect of pressure reduction, realize the slow unlatching of diaphragm 7, come round in feed-water end and waterexit end, water enters water tank, when cistern water level raises, the drainage mouth 2 that pilot valve controls turns down gradually, water level rises to setting height, float ball guided valve cuts out, water in water storage cavity no longer leaks, hydraulic pressure raises gradually, under the effect of pressure reduction, the press water of feed-water end enters epicoele through penstock 1, diaphragm coordinates with turriform spring 5 and falls rapidly under gravity, when flow close to zero time main valve close to stop most of current, realize closing the rising limiting water hammer peak value soon, at the pipeline Bonding pressure table of valve outside, flowmeter, changes the function that the Connecting format of pilot valve can realize pressure release, flow control and Slow Close check, when valve occurs out of control, can regulate float valve, shut pressure release mouth, maintenance easily.
