Abstract
The utility model discloses the on-deformable solenoid valve of a kind of diaphragm, comprise valve body, valve body is provided with the diaphragm unit controlling sprue opening and closing, in the cavity that diaphragm unit is formed between sprue and valve body, the branch pipe(tube) that valve core of the electromagnetic valve controls opening and closing is provided with between cavity and sprue, described diaphragm unit comprises diaphragm and pallet, is provided with catch between diaphragm and pallet.The utility model, by arranging catch between diaphragm and pallet, prevents diaphragm from directly contacting with pallet, utilizes the elastic reaction of catch, avoid the distortion that diaphragm causes due to pressurized, extend the working life of diaphragm and solenoid valve.
Description
Technical field
The utility model relates to a kind of solenoid valve, particularly relates to the on-deformable solenoid valve of a kind of diaphragm.
Background technique
Solenoid valve is the industry equipment by Electromagnetic Control, be used in industrial control system adjust medium direction, flow, speed and other parameter.Solenoid valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure, in this process, diaphragm structure serves key effect, is a core component.Its control principle of the solenoid valve of diaphragm type is: solenoid valve comprises valve body, valve body is provided with the diaphragm unit controlling sprue opening and closing, the large discharge realizing sprue in the cavity that diaphragm unit is formed between sprue and valve body is through, is provided with the branch pipe(tube) that valve core of the electromagnetic valve controls opening and closing between cavity and sprue.The lifting of diaphragm unit, diaphragm serves key effect for the sealing of cavity, and often due to diaphragm deformation in prior art, sealability reduction causes the reduction of the pressure reduction between cavity and sprue to cause diaphragm unit to close sprue.How to prevent diaphragm deformation from causing sealability to decline, the technological deficiency causing solenoid valve to close is the object that those skilled in the art study always.
Summary of the invention
The utility model provides that a kind of structure is simple, the on-deformable solenoid valve of diaphragm of long service life, good seal performance.
The on-deformable solenoid valve of a kind of diaphragm, comprise valve body, valve body is provided with the diaphragm unit controlling sprue opening and closing, in the cavity that diaphragm unit is formed between sprue and valve body, the branch pipe(tube) that valve core of the electromagnetic valve controls opening and closing is provided with between cavity and sprue, described diaphragm unit comprises diaphragm and pallet, is provided with catch between diaphragm and pallet.The solenoid valve of this kind of structure, by arranging catch between diaphragm and pallet, prevents diaphragm from directly contacting with pallet, utilizes the elastic reaction of catch, avoid the distortion that diaphragm causes due to pressurized, extend the working life of diaphragm and solenoid valve.Described pallet and catch surface of contact are circular arc, form a kind of camber line and connect the damage avoiding the rigid connection of linear structure to cause diaphragm.
Described diaphragm, pallet and catch are by rivet, seal ring is provided with between rivet and diaphragm, packing washer is provided with between rivet and pallet, diaphragm unit is made to form an entirety, the connecting port of air outlet section between cavity of the airtight connection main pipeline of ring structure, improves the sealability of diaphragm unit further.
Described catch is the thin rounded flakes structure that diameter is less than diaphragm, catch has more than two equally distributed clearance grooves, clearance groove structure prevents catch owing to being subject to pallet extruding, and the resiliently deformable of self, avoid the diaphragm deformation that flap deformation causes, extend the working life of diaphragm further.
Be provided with Returnning spring between described cavity top and pallet, increase the downforce of pallet, improve diaphragm seal performance.
Be provided with air distribution disk in described cavity, make diaphragm obtain the unlifting pressure of main conduit's air inlet section uniformly, be convenient to make diaphragm unit.
Be provided with sealing seat as the preferred seal ring periphery of structure, prevent sealed ring deformation or breakage.
The utility model, by arranging catch between diaphragm and pallet, prevents diaphragm from directly contacting with pallet, avoids the distortion that diaphragm causes due to pressurized, extend the working life of diaphragm and solenoid valve.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model diaphragm on-deformable solenoid valve sectional structure schematic diagram;
Be illustrated in figure 2 diaphragm unit sectional structure schematic diagram in the utility model;
Be illustrated in figure 3 the structural representation of catch in the utility model.
Embodiment
The on-deformable solenoid valve of a kind of diaphragm as shown in Figure 1, 2, comprise valve body 4, valve body 4 is provided with the diaphragm unit controlling sprue opening and closing, in the cavity that diaphragm unit is formed between sprue and valve body 4, the branch pipe(tube) that valve core of the electromagnetic valve 1 controls opening and closing is provided with between cavity and sprue, diaphragm unit comprises diaphragm 11 and pallet 8, is provided with catch 12 between diaphragm 11 and pallet 8.Returnning spring 3 is provided with as between the preferred cavity top of structure and pallet 8.
Rivet by rivet 5 to improve the integrity diaphragm 11 of diaphragm unit, pallet 8 and catch 12, be provided with seal ring 15 between rivet 5 and diaphragm 11, seal ring 15 periphery is provided with sealing seat 14.Packing washer 13 is provided with between rivet 5 and pallet 8.
As shown in Figure 3 in order to prevent diaphragm 11 to be out of shape further, catch 12 is less than the thin rounded flakes structure of diaphragm for diameter, catch 12 has more than two equally distributed clearance grooves.Pallet 8 and catch 12 surface of contact are circular arc.
The concrete workflow of the utility model is: valve core of the electromagnetic valve 1 closes branch pipe(tube), and the first branch pipe(tube) 9 of branch pipe(tube) and the second branch pipe(tube) 2 cut off mutually, and now diaphragm unit closes the connecting port of air outlet section 7 between cavity of main pipeline.When valve core of the electromagnetic valve 1 opens the first branch pipe(tube) 9 of branch pipe(tube) and the second branch pipe(tube) 2 is interconnected, pressure drop in cavity carries out off-load, in the air inlet section 6 of main pipeline, medium is by air distribution disk jack-up diaphragm unit, medium is flowed out by the connecting port of air outlet section 7 between cavity of main pipeline, after valve core of the electromagnetic valve 1 closes branch pipe(tube), first branch pipe(tube) 9 of branch pipe(tube) and the second branch pipe(tube) 2 cut off mutually, pressure in cavity raises the connecting port between the air outlet section 7 of diaphragm unit decline closedown main pipeline and cavity, realizes the opening and closing of electromagnetic valve main pipeline thus.
