Abstract
The utility model relates to a new spring check valve for the unidirectional flow of liquids and gases in the pump pipe, comprising a valve ball base, a sealed ball, a guiding device, a spring and a baffle; wherein, the sealed ball, the guiding device, the spring and the baffle are all positioned in a big hole of the valve ball base, so that the valve can close in time under the force of the spring to prevent the reverse flow of the liquid.
Description
The utility model spring one-way valve is to be used for liquid, the gas a kind of equipment in the pump line one-way flow.
Because one-way valve is by top power, sphere, thrust one-way valve at present, mainly be by liquid top power and thrust sealing, sticking dead with oil easily in oil, water, and deviation also can take place in spherical seal valve sometimes, causes sealing untimely or airtight not tight, causes refluence.
The utility model one-way valve its objective is the gap that in time seals, closes between ball and the ball valve under the effect of spring force and liquid thrust, prevent that definitely liquid from flowing backwards.
Its structure of the utility model spring one-way valve is such, and it is made up of valve ball seat, airtight ball, orientating device, spring, baffle plate etc.The above valve ball seat becomes cylindrical body, and the two ends car has internal and external threads, or two ends car flange plate, links with other workpiece, and an end is used to block ball sealer than small sircle hole and liquid passes through, and an end is used to put airtight ball and orientating device, spring etc. than big hole.The above airtight ball becomes a spherosome; Above-mentioned orientating device becomes a circle, and an end is bigger, and cooperatively interacts at bottom surface car ball in the arc-shaped and airtight, and an end is less, and socket is on baffle plate; Above-mentioned spring just cover is sitting on orientating device and the baffle plate; Above-mentioned baffle plate becomes a platen surface, cylindrical and valve ball seat upper end are fixing, the centre is drilled with the uniform circular hole of 4-8, is used for liquid and passes through, center drill one circular hole, cooperatively interact with orientating device, when liquid during from the foramen primum high-pressure flow, liquefied gas will back down airtight ball and flow through, when the small sircle hole place forms low pressure area like this, airtight ball in this one-way valve will be in time airtight under the effect of spring force and liquid, prevents that liquid from flowing backwards.
Owing to adopt such scheme, just prevent fully that liquid from flowing backwards, it is simple in structure.
Below, in conjunction with the accompanying drawings the utility model spring one-way valve is described in further detail
Fig. 1: spring one-way valve schematic representation
Its structure of the utility model spring one-way valve is such, and it is made up of valve ball seat 1, ball sealer 2, orientating device 3, spring 4, baffle plate 5 etc.1 one-tenth cylindrical body of above-mentioned valve ball seat, the two ends car has internal and external threads or car that flange plate is arranged, and links with other workpiece, and center one end circular hole is less, is used to stop and enclosed liquid, and circle is bigger in the end, is used to put airtight ball 2, orientating device 3 and spring 4 etc.; 2 one-tenth one spherosomes of above-mentioned airtight ball; 3 one-tenth one circles of above-mentioned orientating device, end circle is bigger, and in the arc-shaped at the bottom surface car, cooperatively interacts with airtight ball 2, and end circle is less, and socket is in baffle plate 5; 5 one-tenth round flat bodys of above-mentioned baffle plate, cylindrical and valve ball seat interfix, be drilled with 4-8 round tube hole uniformly on the median surface, be used for liquid, gas passes through, the center is drilled with a manhole, cooperatively interact with orientating device, set upright, in time compress the gap between airtight ball and the valve ball seat under the effect of the airtight ball of correcting and spring 4 power, prevent that liquid from flowing backwards.
