Description
The present invention relates to a kind of valve, particularly a kind of off-load escape cock with diaphragm valve core.
In modernization industry production and daily life, need to use the valve of a large amount of various types, as be widely used in unloading valve, safety valve in petrochemical system and the general industry hydraulic system; A large amount of discharging valve (being commonly called as water tap) and flashing valves (being used for the flushing of faeces trough and urinal) that use in daily life and the sanitary fittings.The structural type various kinds of these valves, gate valve, cone valve, ball valve, butterfly valve or the like are arranged, but these valves all exist a common characteristic, because working medium pressure acts directly on the spool, make the keying of spool be subjected to the influence of working medium pressure, inlet pressure is high more, and the active force that spool is subjected to is just big more, and unlatching and the closure of handling valve are just difficult more, and the vibration that brings spool thus, a series of shortcomings such as impact and noise.When valve was used for the workplace of high-pressure high-flow and adopts multiple control modes to handle, it is more outstanding that this problem just seems.
Purpose of the present invention is exactly in order to overcome above-mentioned shortcoming, provides a kind of spool not influenced by the import step pressure medium, is convenient to adopt the diaphragm valve of multiple control modes again.
Diaphragm valve of the present invention comprises a valve body, an import, an outlet and a control mouth, be equipped with on the valve body, lower end cap, one cylindrical pressure chamber is arranged in the valve body, one cylindrical diaphragm valve core is housed in pressure chamber, one Returnning spring is housed on its upper-end surface, between the outer surface of this diaphragm valve core and the valve interior surface combination seal is housed, to prevent that the working medium in the pressure chamber from entering spring chamber, the inside formation one of spool is suitable for the cylindrical bore of installation and control piston, match with corresponding ring-shaped valve seats in the annular sword limit that this spool lower end forms, valve seat is to make with the softer material that is different from spool, and under the effect of Returnning spring, this diaphragm valve is in normally off.In the cylinder chamber of diaphragm valve core a control piston is housed, this piston preferably and piston rod is whole forms, seal ring is housed on the piston, and piston rod and lower end cap are rigidly connected, and the cylinder body of diaphragm valve core can slide between the outer surface of control piston and valve interior surface.In piston rod, be formed centrally the control channel of always wearing piston and lower end cap, the control mouth is communicated with the cylinder chamber, control oil enters the cylinder chamber through this passage, pressure oil acts on the upper surface in spool cylinder chamber, spool overcomes Returnning spring power and opens, import is communicated with outlet, thereby reaches the purpose of off-load discharging.Because the diaphragm valve core is cylindrical, its balanced radial force, the area on the annular sword limit that its lower end forms is very little, when opening, be subjected to the effect of oil pressure hardly with closure, therefore, the axial force on the spool is also very little, thereby spool can be opened and closure like a cork, therefore, diaphragm valve is particularly suitable for the workplace of high-pressure high-flow.
Diaphragm valve of the present invention is compared with existing all kinds of valves, and is novel, unique, simple and reasonable, is convenient to processing and use.It is not subjected to the influence of working medium pressure size when work, be convenient to handle, can adopt multiple control modes that spool is handled, as hydraulic control, manual control and Electromagnetic Control etc., be specially adapted to use as fast unloading valve, and the sealing at spool and valve seat place is reliable in the workplace of high-pressure high-flow.
Below in conjunction with accompanying drawing the present invention is done detailed explanation.
Fig. 1 is the sectional drawing of first embodiment of the invention.
Fig. 2 is the sectional drawing of second embodiment of the invention.
Fig. 3 is the sectional drawing of manual control part of the present invention.
Fig. 4 is the sectional drawing of electromagnetic control components of the present invention.
Referring to Fig. 1, the fast unloading valve that the present invention that shown in Figure 1 is is constituted when being used for the hydraulic system off-load, the import P of this unloading valve (not shown) that is connected with the hydraulic system pressure loop, outlet O is connected with the hydraulic system oil circuit and the (not shown) that communicates with fuel tank.The control oil channel H of control channel C and system joins, hand control valve 13 control oil-feed or oil returns.When the hydraulic system proper functioning, hand control valve right position work, the control oil that system comes is drawn oil sump tank, and diaphragm valve core 4 is being pressed on the ring-shaped valve seats 3 under the effect of Returnning spring 11, and the pressure oil among the B of annular pressure chamber can not be communicated with oil drain out O.When system needs quick relief, the position work of hand control valve 13 left side, control oil enters control channel C in lower end cap 1, piston rod 23 and the piston 24 through valve 13, flow into cylindrical bore A, because piston 24 maintains static, control oil acts on the end face K of cylinder chamber, make spool 4 overcome spring force and upwards rapid moving, spool is opened, and pressure oil is discharged from outlet O and flowed into fuel tank, thereby reaches the purpose of quick relief.The size of valve port opening can be adjusted by the relation between control-oil pressure and the spring rate, and its maximum opening is limited by the stroke of diaphragm valve core.
The unlatching that can also adopt the outer manual control oil cylinder of valve body to come control cylinder formula spool.In addition, manual control part as shown in Figure 3 can be installed on the position of diaphragm valve upper end cap 9, it comprises a handle 25, adjustable lever 29, snap ring 27 and end cap 28, and rotatable handle 25 not only can manual opening-closing spool 4, and can adjust the maximum opening (when adopting hydraulic control) of spool 4.Also can adopt electromagnetic control components as shown in Figure 4, it comprises electromagnetic core 31, electromagnetic coil 32, plug screw retaining ring 30 and top cover 26.Coil electricity, iron core 31 actions drive spool 4 and open, and behind the coil blackout, spool 4 is closed under the effect of Returnning spring.
Referring to Fig. 2, shown in Figure 2 is the flashing valve that the present invention is used for sanitary equipment, can be used on the washbasin in the hospital, the faeces trough and urinal in the toilet etc.The outlet of valve can be installed in any needed position, and the pedal 16 of foot-operated small oil tank G can be installed in the position of being convenient to the operation of people's pin.When needs washed, as long as gently step on the piston 15 of small oil tank G, the liquid among the oil cylinder G was squeezed, and enters cylinder chamber A from control channel, promoted the unlatching of spool 4, and the pressure flow among the pressure chamber B flows out the O mouth.Pin unclamps from pedal 16, and current just are cut off.The flow of flushing can be regulated by the stroke of adjusting small oil tank piston 15, and the stroke of piston 15 is long, and it is big to squeeze the amount of liquid that, and the aperture of spool 4 is also big, so the flow of flushing is just big.Otherwise flushing dose is just little.
When flushing valve needs automatic delay function, can adopt as shown in Figure 2 one-way valve D and time-delay adjustment valve 18 to realize.After small oil tank G is losing external force and is automatically reseting, at this moment, because control oil duct F is closed by the steel ball 21 of one-way valve D, liquid can only be adjusted valve (being throttle valve) through time-delay from throttling passage E and return small oil tank G, at this moment, the openings of sizes that valve 18 is adjusted in time-delay has just determined liquid to flow back to the speed of small oil tank G, thereby has determined the time of spool 4 time-delay closings, i.e. Chong Xi time.
This valve is used for the faeces trough and urinal and the washbasin (the especially washbasin of hospital) of toilet, can thoroughly solve toilet establishes the people and dashes; urinal running water and washbasin water tap cause problems such as cross infection disease, thereby has reached the purpose of water saving, health.
