Embodiment
Below in conjunction with specific embodiment and accompanying drawing, non-return electromagnetic gas valve of the present utility model is described in further detail.
As shown in Figure 1, in a preferred embodiment, non-return electromagnetic gas valve of the present utility model, for Pneumatic massage system.It mainly comprises: for preventing the check valve 100 of the reverse outflow of gas, control the solenoid valve 200 of inflation or venting.
In the present embodiment, check valve 100 comprises the cavity body 111 that is provided with air inlet and goes out vent hole and is arranged at the antireverse valve spool 120 in chamber, two through holes of cavity body 111 are the wherein subtend opposite in cavity body 111 respectively, its air inlet through hole 112 place faces are detachable, facilitate the assembling of antireverse valve spool 120, this face is connected with parent by screw.Antireverse valve spool 120 makes the gas can only one-way flow.The suction port that goes out vent hole and solenoid valve 200 of check valve 100 is tightly connected.Solenoid valve 200 inside are provided with an electromagnetism bouncing mechanism 230.Realize aerification function or venting function for controlling.There are two gas ports that are in communication with the outside at 221 places, air outlet of solenoid valve 200, one be for the air outlet 221 to Pneumatic massage system inflation, it two is leakage port 222.
For check valve 100 of the present utility model, as shown in Figure 3 or Figure 4.The antireverse valve spool 120 being arranged in check valve 100 mainly comprises non-return soft rubber cushion 121 and ventilating part 122.Ventilating part 122 is the blocks that tow sides all concave, and its size adapts with cavity inside, indent be shaped as circle, be convenient to coordinate assembling.Interior recess is equipped with three vents 124 that run through ventilating part 122, is provided with out a flexible glue pad hole clipping 127 at the circle centre position of indent, runs through equally ventilating part 122, for being fixed non-return soft rubber cushion 121.In order better ventilating part 122 to be fixed in cavity body 111, ventilating part 122 sides have groove around it, and groove is provided with seal ring 123.Effectively fix ventilating part 122 and block gas and pass through from its side and cavity body 111 inwall gaps.
Non-return soft rubber cushion 121 is a rubber shim, its shape and size match with the shape of ventilating part 122 interior recesses, make it can cover the vent 124 of ventilating part 122 completely, its circle centre position upwards vertically extends a card column 125, card column 125 ends have interface arrangment 126, in the time that non-return soft rubber cushion 121 is installed to ventilating part 122, card column 125 is stuck through the rear clamping mechanism 126 by card column 125 of flexible glue pad hole clipping 127 of ventilating part 122, and it can not be come off from ventilating part 122 easily.
For solenoid valve 200 parts, as shown in Figure 1, Figure 2 with shown in Fig. 5.Solenoid valve 200 also comprises hollow cylinder 210 and loading chute 220, and hollow cylinder 210 and loading chute 220 design or are welded to connect for integral type.Electromagnetism bouncing mechanism 230 is arranged in hollow cylinder 210, and it comprises electromagnet 231, spring 232 and iron core 233.Wherein electromagnet 231 is fixed on hollow cylinder 210 one end near described check valve 100, and magnetic pole is towards iron core 233.Iron core 233 is a cylindrical iron bar, radius is slightly less than the inside radius of hollow cylinder 210, it is positioned over hollow cylinder 210 inside, can in hollow cylinder 210, move around, soft rubber stopper 234 is equipped with respectively at its two ends, at the groove that has a placement spring 232 near electromagnet 231 one end, make spring 232 not hinder contacting of electromagnet 231 and iron.Between iron core 233 and electromagnet 231, be provided with a Compress Spring 232.For better ventilation, vent slot has been cut in iron core 233 sides.
Outlet pipe and the air outlet 221 of solenoid valve 200 extended in loading chute 220 outlet sides, outlet pipe radially with the barrel dliameter of open circles to vertical.In the present embodiment, exhaust mechanism is a leakage port 222, is arranged on the intersection of outlet pipe and hollow cylinder 210.Described exhaust mechanism is communicated with described air outlet 221.Its round table-like projection that extends internally out, for coordinating sealing gas port with soft rubber plug.
In the present embodiment, when non-return electromagnetic gas valve inflation, gas, under the promotion of air pump, enters non-return electromagnetic gas valve from suction port, and under the effect of pressure, the non-return soft rubber cushion 121 in check valve 100 is rushed to open; And electromagnetism bouncing mechanism 230 does not switch on power, under the effect of spring 232 self elastic force, electromagnet 231, is flowed out by air outlet 221 leakage port 222 closures near one end of leakage port 222.When non-return electromagnetic gas valve pressurize, air pump cuts out, and gas carries out back pressure, and under the effect of air pressure, check valve flexible glue pad is dead the sealing of three inlet holes, gas is carried out completely airtight, thereby play pressurize effect.When non-return electromagnetic gas valve loses heart, electromagnet 231 is switched on, iron core 233 is adsorbed by electromagnet 231 under electromagnetic action, and now leakage port 222 is opened, and the gas in Pneumatic massage system discharges, and realizes and losing heart.
Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all such substituting, improve and change are all included in the spirit and scope of attached claim.
