All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-6, the present utility model provides a technical solution: the liquid material control valve comprises a valve body 1, a through hole 4 arranged in the valve body 1 and a valve body;
the mounting frame 11 is arranged on the valve body 1 and communicated with the through hole 4;
the valve clack 5 is arranged in the through hole 4 in a sliding sealing manner;
the limiting component 9 comprises a movable rod 6 arranged on the valve clack 5, a clamping block 91 used for positioning the movable rod 6 and a torsion spring 94 arranged on the mounting frame 11, wherein a plurality of clamping grooves 8 matched with the clamping block 91 are formed in the movable rod 6, and one end of the torsion spring 94 is connected with the clamping block 91 and matched with the clamping block 91 to limit the movable rod 6 to move unidirectionally. The liquid gets into valve body 1, then let in from the below of opening 4, then the valve clack 5 is ejecting from the upper portion of opening 4 under the pressure effect of liquid, valve clack 5 drives movable rod 6 and moves upwards, make fixture block 91 joint fix in draw-in groove 8 of seting up on movable rod 6, and the movable rod 6 can only upwards move under the effect of torsional spring 94, make when the pressure of liquid to valve clack 5 reduces, the opening size between valve clack 5 and the opening 4 is unchangeable, thereby the flow of liquid inflow valve body 1 inside is unchangeable, when the pressure of liquid increases, valve clack 5 drives movable rod 6 and moves upwards, become the opening size between valve clack 5 and the opening 4, can play the control valve clack 5 and opening 4 in the certain within range of liquid pressure variation, the condition of material jam mouth can effectually be reduced.
Wherein, the installation frame 11 is provided with the connecting rod 92 in a sliding way, and the fixture block 91 and the torsion spring 94 are respectively sleeved at one end of the connecting rod 92, and the connecting rod 92 is provided with a fixed ring 93 for connecting the other end of the torsion spring 94. In the process that the movable rod 6 moves upwards, the clamping block 91 rotates to the side far away from the movable rod 6 along the connecting rod 92, then the torsion spring 94 is extruded, when the clamping block 91 moves to the position of the clamping groove 8, the torsion spring 94 drives the clamping block 91 to move to the side close to the movable rod 6, the clamping connection is fixed in the clamping groove 8, under the action of the torsion spring 94, the movable rod 6 can only move upwards, and when the pressure of liquid on the valve clack 5 is reduced, the opening between the valve clack 5 and the through hole 4 is reduced, and the conveying quantity of the liquid is influenced.
Wherein the other end of the connecting rod 92 passes through the mounting frame 11 and is provided with a pull rod 95. After the liquid conveying work is completed, the liquid does not have pressure on the valve clack 5 any more, and then the pull rod 95 is pulled, so that the connecting rod 92 drives the clamping block 91 to be pulled out from the clamping groove 8, and then the moving rod 6 is adjusted to move downwards, so that the valve clack 5 is sealed in the through hole 4, and the reset work on the valve clack 5 is realized.
Wherein, the guide ring 7 for the moving rod 6 to pass through is arranged right above the through hole 4 in the mounting frame 11. The guide ring 7 may restrict the moving state of the moving lever 6 so that the moving lever 6 can only move up and down.
The upper portion of the installation frame 11 is provided with an adjusting component 10 for controlling the upward movement height of the valve clack 5, the adjusting component 10 comprises a screw 102 penetrating through the top plate of the installation frame 11, a turntable 101 is fixed at the top of the screw 102, a top block 103 is fixed at the bottom of the screw, and the top block 103 is adjustably arranged between the top of the moving rod 6 and the top plate of the installation frame 11 under the driving of the screw 102. When the material of the formulation flow is required to be carried, through rotating carousel 101 for screw rod 102 drives kicking block 103 and moves down, then kicking block 103 moves down in the inside of installing frame 11, and the maximum distance that carriage release lever 6 upwards moved is restricted, thereby can adjust the opening of opening between valve clack 5 and opening 4 according to the user demand, adjusts the delivery volume of material according to the user demand, and when the control valve is used completely, can drive carriage release lever 6 through kicking block 103 downwardly moving, makes valve clack 5 seal in the inside of opening 4.
Wherein, one side of valve body 1 is fixed with feed inlet 2, and the opposite side is fixed with discharge gate 3, and feed inlet 2 is linked together with the bottom of opening 4, and discharge gate 3 is linked together with the top of opening 4. The material flows in from one side of the feed inlet 2, opens the valve clack 5 at the upper end of the through hole 4 under the action of pressure, then discharges from the discharge hole 3, and adjusts the gap between the valve clack 5 and the opening 4 under the drive of the adjusting part 10, thereby realizing the control of the conveying quantity of the material.
Working principle: when the valve is used, liquid material flows in from one side of the feed inlet 2, the valve clack 5 at the upper end of the through hole 4 is opened under the action of pressure, then the valve clack 5 is discharged from the discharge hole 3, when the material with a set flow is required to be conveyed, the screw 102 drives the top block 103 to move downwards through rotating the rotary disc 101, then the top block 103 moves downwards in the installation frame 11, the maximum distance of the upward movement of the moving rod 6 is limited, accordingly, the opening opened between the valve clack 5 and the through hole 4 can be regulated according to the use requirement, the valve clack 5 drives the moving rod 6 to move upwards according to the conveying amount of the material, the clamping block 91 is clamped and fixed in the clamping groove 8 formed in the moving rod 6, and the moving rod 6 can only move upwards under the action of the torsion spring 94, so that the opening size between the valve clack 5 and the through hole 4 is unchanged when the pressure of liquid to the valve clack 5 is reduced, when the pressure of the liquid is increased, the valve clack 5 drives the moving rod 6 to move upwards, the opening between the valve clack 5 and the through hole 4 is greatly changed, the opening between the valve clack 5 and the through hole 4 can be effectively controlled within a certain range, the opening between the valve clack 5 and the valve 4 is effectively blocked when the opening is greatly controlled, and the opening between the valve 4 is effectively controlled to move down when the valve opening is greatly controlled, the opening is opened, and the opening is greatly controlled, and the opening is effectively under the opening inside the opening is sealed.
