Description
The utility model relates to the liquid filling device technical field of liquid being injected in the containers such as bottle.
The quantitative perfusion valve of using always in filling liquid machinery can't be finished two kinds of capacity high precision perfusions with same valve at present; No matter be quantitatively cup type or the plunger tpe pouring valve will be changed the different bottle of capacity, will change pouring valve or bottle placer; Though can adapt to the bottle of different capabilities etc. the liquid level pouring valve, can't realize that high precision quantitatively pours into.
The purpose of this utility model provides a kind of switching capacity rapidly, high-precision double volume type precise quantity perfusion valve.
For achieving the above object, the technical solution of the utility model is: it comprises that its upper end that sealing is installed in fluid reservoir bottom has the outer valve of pilot hole, inlet opening and taper inlet; Outer valve has a stream line pattern master chamber and a plunger shaft; The valve body lower end inner tight is being fixed inner valve body outside, and it is separated into an exocoel and an inner chamber with main chamber; Piston and seal ring are housed in the plunger shaft, and plunger shaft is equipped with lid outward.
The upper valve core and the bottom spool of the slide relative that is nested together are housed in the pilot hole of outer valve upper end, between upper valve core and the bottom spool valve-closing spring are housed.Upper valve core has conical surface plush copper and valve pad is housed, in order to the taper inlet on the sealing outer valve; Also have conical surface plush copper on the bottom spool and valve pad is housed down, in order to the liquid outlet channel at the bottom of the draught excluder.The upper valve core top has its outside that is sleeved on the bottom spool to have the sliding sleeve of annular groove, and there is nut and the tracheae that is contained in the bottom spool upper end sliding sleeve top, and upper valve core, tracheae and sliding sleeve are outer by sylphon seal.The bottom spool middle part has a ventilation orifice to communicate with atmosphere in the fluid reservoir by tracheae.
Valve body lower end is equipped with nut outward outside, and ejector pin and spring are housed in the nut; At the bottom of valve being housed between on the nut, under the inner valve body, locating dowel pin is housed at the bottom of the valve.The inner valve body bottom has inner conical surface and fluid hole, and has the liquid outlet channel of a male cone (strobilus masculinus) and a bell at the bottom of the valve, the inner conical surface sealing of its male cone (strobilus masculinus) and inner valve body, and top has fluid groove, and seal ring is housed at the bottom of the valve and between the outer valve.Suit the orientating device that has inner conical surface outside the liquid outlet channel at the bottom of the valve, and orientating device top has translot, and holder ball pin and steel ball are housed in the hole of translot downside.The orientating device bottom has vertical air flue, annular gas tank and pore.
Also sealing and fixing has conduit in fluid reservoir bottom, and guide pin bushing, cushion and the push rod of slippage up and down are housed in the conduit.The push rod upper end is equipped with upper shift fork, and another end yoke of upper shift fork is in the annular groove of sliding sleeve; Lower shift fork is equipped with in the push rod lower end, and another end yoke of lower shift fork is in the translot of orientating device.Between conduit bottom and lower shift fork, retracing spring is housed.Conduit and push rod upper end are by sylphon seal.
Bottle rises, at first by the orientating device correcting and head on orientating device and rise together, make lower shift fork, push rod and upper shift fork and sliding sleeve with on move, under the valve-closing spring effect, upper valve core is closed inlet with moving on the sliding sleeve, and then sliding sleeve is mentioned bottom spool, open liquid outlet channel, this moment exocoel liquid by the fluid hole of inner valve body bottom and valve at the bottom of the fluid groove of upper end inject bottle through liquid outlet channel, inner chamber liquid also injects bottle through liquid outlet channel simultaneously; Gas then enters inside and outside chamber by the ventilation orifice at tracheae and bottom spool middle part, and vertical air flue, annular gas tank and the pore of the gas in the bottle on orientating device discharged, and reaches the perfusion purpose.Otherwise bottom spool moves down, and closes liquid outlet channel, and sliding sleeve is depressed upper valve core immediately, opens the taper inlet, and liquid enters inside and outside chamber; Gas is through the ventilation orifice at bottom spool middle part and the taper inlet exhaust to atmosphere on the outer valve.
To forward another control position at the bottom of the valve to, the male cone (strobilus masculinus) at the bottom of the valve is blocked the inner valve body fluid hole, and a part of liquid in the exocoel is just sealed can not enter bottle, reaches the purpose of switching capacity.When rotating at the bottom of the valve, spring by ejector pin with valve at the bottom of the male cone (strobilus masculinus) roof pressure on the inner conical surface of inner valve body, cause internal leakage in order to avoid impurity enters sealing surface, influence perfusion precision.
Piston position can change and the fine setting capacity reaches smart amount perfusion by adjusting.
The utlity model has following advantage: once be by rotating valve at the bottom of switching capacity rapidly, simple to operate, reliable operation; The 2nd, streamlined structure is adopted in the main chamber of outer valve, and perfusion precision and speed are further improved.
