Detailed description of the invention
Further describe the utility model below in conjunction with Figure of description, and give embodiment of the present utility model.
This pneumatic type definite quantity filling valve as shown in Figure 1, comprise main valve body 5, valve rod 10, valve gap 8, flap 13, valve body bottom 2, drive cylinder 11, it is characterized in that: described main valve body 5 inner chamber is divided into top masuring room 19, middle part diversion chamber 18, and form bottom diversion chamber 25 with the valve body bottom 2 being arranged on the outer bottom of main valve body again; Described valve rod 10 is arranged in masuring room 19, and its upper end is stretched out valve gap 8 and is connected with driving the piston rod 24 of cylinder 11, and its end being positioned at the hypomere body of rod of masuring room is provided with piston 6, forms the piston drive mechanism in masuring room thus; The side main valve body of described middle part diversion chamber 18 is provided with one as the side non-return valve B of fluid output interface, is provided with one as the bottom non-return valve A of fluid input interface in described bottom diversion chamber 25; Described piston rod 24 is connected by a fine-tuning nut 12 with valve rod 10.
Owing to adopting above-mentioned three-in-one structure, the fluid making needs filling enters middle part diversion chamber 18, top masuring room 19 from bottom non-return valve A, the piston 6 utilizing the driving cylinder 11 be provided with on same main valve body to drive, utilizes piston to press down and is transported in tank body through side non-return valve B by all dosed fluids be stored in masuring room.
In technique scheme, the spatial volume of masuring room designs according to adopted tank volume.In order to prevent a small amount of error occurred in pouring process, therefore a fine-tuning nut 12 is set in the technical program between valve rod and piston rod, utilize the positive and negative screw thread that the internal diameter of fine-tuning nut 12 has, make piston 6 realize trace adjustment downward or upward, thus reach the object of adjustment masuring room volume.
Top masuring room 19 in described main valve body 5, middle part diversion chamber 18 joint portion are provided with convex bank 26, this convex bank 26 top is masuring room 19, bottom is middle part diversion chamber 18, and described middle part diversion chamber 18 is through with middle part diversion chamber 18 by the pod apertures 14 be located at bottom main valve body 5.
Bottom non-return valve A is as described in Figure 2 made up of valve body bottom 2, the flap 13 be located in the diversion chamber 25 of bottom, bottom valve valve gap 3, described flap 13, bottom valve valve gap 3 form " work " font workpiece by a pipe link, on described pipe link, string overlaps spring, described top flap 13 is embedded in the centre hole bottom main valve body, described bottom valve valve gap 3 is seated in the entrance of bottom non-return valve A, forms the fluid input interface that pneumatic type definite quantity filling valve has return-stopping function.
When valve outer fluid needs to enter masuring room 19, under the state that the external world exerts pressure, the effect that bottom this, flap 3 of non-return valve A overcomes spring 16 upwardly opens, extraneous fluid enters main valve body 5 inner chamber from bottom non-return valve A entrance through the pod apertures 14 of main valve body bottom design, until fill all valve pockets, treat that external fluid stops entering, the flap 3 bottom the non-return valve A of bottom oppositely closes entrance under the action of the spring 16.
Side non-return valve B as described in Figure 2 comprises side valve body 15, be located at the side valve flap 21 of side body cavity, side valve spring 22 and side valve base 20 is formed, described side non-return valve B is connected on the openings of middle part diversion chamber 18 in side non-return valve B and main valve body, described side valve spring 22 to be arranged on outside side valve spring 22 and to be fixed in the valve pocket of side non-return valve B of hollow form through side valve base 20, forms the fluid output interface of pneumatic type definite quantity filling valve.
When valve rod 10 presses down with piston 6, because the flap 3 bottom the non-return valve A of bottom is closed under the action of the spring 16, therefore the dosed fluid in all masuring rooms 19 pressed down overcomes the elastic pressure of side valve spring 22, the side valve flap 21 pushing the side body cavity designed in side non-return valve B open makes this side non-return valve B be in conducting state, allow the dosed fluid in masuring room flow into want in filling tank body.Once after having filled with, this side non-return valve B, under the effect of side valve spring 22 elastic pressure, has closed side non-return valve B by closedown side valve flap 21 again and has completed expendable process.Thus, it is filling that the motion gone round and begun again along with external fluid and cylinder completes again and again.
For the ease of processing a small amount of accretion causing body cavity to occur that works long hours, therefore on the outer bottom 2 of valve body, be provided with atmospheric valve of removing contamination.
Below be only the basic embodiment that the applicant proposes according to design, any improvement proposed by this basic conception, all belongs to the category of the utility model protection.
