Description

Portable loading anti-overflowing valve

The utility model relates to a kind of portable can anti-overflow valve, belongs to valve type.

At present, oil depot is in the barrel filling hair oil work of product oil, usually adopt common nozzle or conventional valve in bucket, to irritate oil, because the filling hydraulic fluid port diameter of oil drum is very little, operator must watch the hair oil mouth nervously attentively in the process of hair oil, in order to avoid oil is full excessive, thereby causes the labor intensity of operating staff increase and bear the stifling hardship of oil gas.

The purpose of this utility model is to overcome the defective of prior art, provide a kind of can alleviate labor intensity of operating staff, easy to use, have a portable can anti-overflow valve that automatic anti-overflow closes valve.

The utlity model has housing, vertically disposed inlet connector tube and outer pipe, be provided with valve seat, valve rod and valve gap in the housing, the interior valve seat rear side setting of housing has the spray of taper mouth and inhales cover, and the small-bore position that the spray suction is overlapped is offered ring shape groove And and at this position cylindric nozzle pipe is set; The movable setting by spring presses to the tapered plug that cover is inhaled in spray on the valve rod; Be provided with the air chamber that is divided into by film at housing inner valve stem opposite position, And is in communication with the outside air chamber, circular groove by three-way pipe, and wherein a siphunculus is arranged on the sensing port of its opening formation anti-overflow valve in the outlet tube wall; Between air chamber and valve rod, also be provided with manual and automatic-closing valve actuator.

Further specify the utility model below in conjunction with embodiment.

Accompanying drawing is the topology view of present embodiment.

Present embodiment is provided with housing 2, vertically disposed inlet connector tube 1 and outer pipe 21, is provided with valve seat 6, valve rod 11 and valve gap in the housing 2.Valve seat 6 rear side settings have the spray suction cover 7 of taper mouth in the housing 2, and the small-bore position of spray suction cover 7 is offered circular groove 23 And cylindric nozzle pipe 8 is set at this position; The movable setting by spring 10 presses to the tapered plug 9 that cover 7 is inhaled in spray on the valve rod 11; Be provided with the air chamber 24 ， And that are divided into by film 17 at housing 2 inner valve stem 11 opposite positions and by three-way pipe 20,25,26 air chamber 24, circular groove 23 be connected with extraneous, pipe 20 is arranged on the sensing port 22 of its opening formation anti-overflow valve in outer pipe 21 walls; Certainly, film 17 opposite sides also are communicated with ambient atmosphere.Between air chamber 24 and valve rod 11, also be provided with manual and automatic-closing valve actuator.

Above-mentioned manual and automatic-closing valve actuator is made of the springs 18 that are located in the control taper pin 15 on the film 17, the setting sleeve 12 that connects with valve rod 11 and the air chamber 24, and the end that is hinged on the housing 2 acts on the handle 14 of setting sleeve 12; Control taper pin 15 is assemblied on the air chamber base 16, the cylinder that air chamber base 16 forms is provided with radially circular hole, ball 13 is set in the circular hole, setting sleeve 12 is set as the ring-type conical surface in being provided with the 15 assembly head hole enlargements of control taper pin, is provided with in the setting sleeve 12 and can acts on the push rod 27 that control taper pin 15 And have spacing with it.

For making valve closing reliable, valve gap divides main valve lid 5, pays valve gap 4, and main valve lid 5 assembling valve seats 6 pay valve gap 4 assembling main valve lids 5, pay between valve gap 4 and the import and are provided with spring 3; Handle 28 also is set on the housing 2.

During work, pull handle 14, stir setting sleeve 12 and valve rod 11, back down the main valve gap 5,4 of paying, oil stream flows to the spray that is made of valve seat 6, spray suction cover 7 and spray suction pipe 8 by inlet connector tube 1 and inhales the chamber, and the spring force that overcomes spring 10 makes tapered plug 9 displacements, and oily stream flows into oil drum from outer pipe 21; At the same time, spring 18 in the air chamber 24 promotes film 17 and control taper pin 15 moves axially, the cross component force extruding ball 13 that the awl curved surface of control taper pin 15 produces is outstanding outside circumference, makes to pin with And the inner conical surface of setting sleeve 12, and setting sleeve 12 is positioned at the valve opening position.According to bernoulli principle, when oil is flowed through spray suction chamber, tapered plug 9 and spring 10 make the fluid from nozzle pipe 8 form high-velocity fluid, the result of high-speed fluid ejection makes and produces negative pressuren zone in the circular groove 23, thereby suck atmosphere by pipe 20, owing to there is atmosphere constantly to replenish, air chamber 24 internal pressures that are communicated with negative pressuren zone in the circular groove 23 still equal or are approximately equal to barometric pressure, and the pressure of film 17 both sides is in state of equilibrium.When the pasta in the oil drum rises when having flooded the sensing port 22 of outer pipe 21 gradually, atmosphere can not enter the negative pressuren zone that replenishes circular groove 23, at this moment, gas is taken out most formation negative pressure, film 17 pressure at both sides disequilibriums in the air chamber 24 that is communicated with circular groove 23, then film 17 oppositely moves together with control taper pin 15, ball 13 forfeiture cross component forces, under spring 3 effects, setting sleeve 12 also oppositely moves together with valve rod 11, a main thereupon pair valve gap 5,4 is closed, and cuts off oil circuit.In the course of the work, as required, oppositely pull handle 14, control taper pin 15 is resetted, realize manually closing valve by push rod 27.

The utility model can be realized manually and automatic closing owing to adopt said structure, prevents that fluid is excessive, has alleviated operator's working strength, has guaranteed oil storage safety barrel filling hair oil.
