Background technique

One-way throttle valve is a kind of of valve body, well known common.By one-way throttle valve adjusting gas flow, can effectively meet the movement velocity of executive component.Notification number is that CN102966771A discloses " a kind of one-way throttle valve ", comprise valve body, be located at the valve core case on valve body, on described valve body, form suction port, valve pocket and air outlet, in described valve core case, form spool chamber, described spool chamber is communicated with valve pocket by valve port, described suction port is communicated with spool chamber by upper runner, in described spool chamber, can be provided with up or down spool, spool bottom setting corresponding to valve port, on spool, be fixedly connected with screw rod, described screw rod upper end is connected with nut through the screw on valve core case, described valve pocket bottom is provided with bonnet nut, described suction port is communicated with valve pocket by lower flow channel, lower flow channel place correspondence is provided with sealing seat, described sealing seat and bonnet nut are provided with Compress Spring.

When being rotated counterclockwise nut and screw rod, on spool, move, now suction port and valve pocket are in connected state, gas carries out valve pocket from suction port, and valve pocket internal air pressure raises, and crush seal seat moves down, lower flow channel is opened, a gas gas enters valve pocket from lower flow channel, through air outlet, discharges, and this one-way throttle valve is in opening state; When turning clockwise nut and screw rod, spool moves down, and suction port and valve pocket be in closed condition, and valve pocket internal air pressure reduces, and sealing seat moves under the effect of Compress Spring, sealing lower flow channel, and now this one-way throttle valve is in closed condition.

Yet because this one-way throttle valve is when opening or cutting out, all need artificial rotary nut and screw rod, this manual mode of operation automaticity is lower, causes working efficiency lower.

Model utility content

The purpose of this utility model is for the defect of prior art and deficiency, and a kind of simple and reasonable, easy to operate, one-way throttle valve that automaticity is higher is provided.

For achieving the above object, the utility model is by the following technical solutions:

A kind of one-way throttle valve described in the utility model, comprise valve body, be located at the valve core case on valve body, on described valve body, form suction port, valve pocket and air outlet, in described valve core case, form spool chamber, described spool chamber is communicated with valve pocket by valve port, described suction port is communicated with spool chamber by upper runner, in described spool chamber, can be provided with up or down spool, spool bottom setting corresponding to valve port, described valve pocket bottom is provided with bonnet nut, described suction port is communicated with valve pocket by lower flow channel, described lower flow channel place correspondence is provided with sealing seat, between described sealing seat and bonnet nut, be provided with Compress Spring A, in described valve core case, be also provided with electromagnetic assembly, described electromagnetic assembly comprises static iron core, be located at the moving iron core of static iron core below and the coil of setting corresponding to static iron core, described moving iron core lower end is fixedly connected with described spool, described coil is electrically connected to control switch, between described static iron core and moving iron core, be provided with Compress Spring B.

Further, in described upper runner, be provided with pressure transducer, described pressure transducer is electrically connected to control switch.

Further, described spool bottom periphery is provided with seal ring.

The beneficial effects of the utility model are: by the electromagnetic assembly consisting of static iron core, moving iron core and coil is set, moving iron core lower end is fixedly connected with spool, by control switch to coil electricity, static iron core produces the moving iron core of electromagnetic attracting force, and then be with movable valve plug to move upward, realized automatic unlatching of the present utility model; When coil losing electricity, the electromagnetic force of static iron core disappears, and spool moves down, and the utility model enters closed condition.The utility model automaticity is high, easy to operate.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

One-way throttle valve as shown in Figure 1, comprise valve body 1, be located at the valve core case 2 on valve body 1, on described valve body 1, form suction port 3, valve pocket 4 and air outlet 5, in described valve core case 2, form spool chamber 6, described spool chamber 6 is communicated with valve pocket 4 by valve port 7, described suction port 3 is communicated with spool chamber 6 by upper runner 8, in described spool chamber 6, can be provided with up or down spool 9, the setting corresponding to valve port 7 of spool 9 bottoms, described valve pocket 4 bottoms are provided with bonnet nut 10, described suction port 3 is communicated with valve pocket 4 by lower flow channel 11, described lower flow channel 11 place's correspondences are provided with sealing seat 12, between described sealing seat 12 and bonnet nut 10, be provided with Compress Spring A13.
