Produce the low discharge two-way valve of product technology requirement.
What the technical solution of the utility model was realized in：
A kind of low discharge two-way valve, including valve body, ball, connect spiral shell, spring and sealing gasket；
The valve body is middle thin, two short and thick ladder pipes, and intermediate coaxial is provided with the coaxial aperture for being used for accommodating ball, described same
Axis hole both sides coaxial-symmetrical is sequentially provided with slotted eye and screwed hole, the coaxial aperture radial equipartition have three it is identical with coaxial hole length
Guiding gutter, and the cross-sectional area of the slotted eye is more than the circumscribed circle cross-sectional area that is formed of three guiding gutters in coaxial aperture；It is close
Packing is placed in the valve body slotted eye；
The spiral shell that connects is provided with the external screw thread coordinated with valve body screw thread hole, and expansion is provided with close to ball one end in the spiral shell internal thread that connects
Platform hole, Spring Card is in platform hole is expanded and one end is in contact with ball, and the expansion platform hole coordinates with spring outer diameter gap；The expansion platform hole
Inner end hole side is provided with the conical surface for being used for that sealing to be kept with ball；Make it is described connect spiral shell and fastened respectively with the valve body, ball respectively with both sides
The free end of spring is in contact, and valve body coaxial aperture, connects spiral shell and expands platform hole, connects chamber that the spiral shell conical surface formed and ball is dynamic coordinates composition small
Flow two-way valve.
Spiral shell and valve body are connect in order to facilitate fastening, it is preferred that connecing that spiral shell is externally threaded outer to be terminated with six sides described.
In order to better adapt to the working environment under High Voltage and higher temperature, the material of the sealing gasket is red copper, institute
The material for stating spring is stainless steel.
Operation principle of the present utility model is：Low discharge two-way valve receives the pressure signal that both ends are transmitted, by intermediate
Different working conditions is realized in side-to-side movement；
Specially：
When pressure difference is less than critical value（Including p1=p2）, ball is centrally located under the action of the spring, at two-way valve
In opening, the relatively high one end of pressure can flow to low one end；
Work as pressure difference（I.e.：p1＞ p2Or p2＞ p1）During more than critical value, ball in the presence of higher pressure, to pressure compared with
Low side movement, makes ball be placed in the low side of pressure, two-way valve is in cut-off state.
The beneficial effects of the utility model are：
（1）Because ball and valve body are linear contact lays, opposite flow resistance is small, suitable for low discharge working environment；
（2）Because the material of sealing gasket is red copper, the material of spring is stainless steel, is suitable under High Voltage and higher temperature
Work；
（3）Simple and compact for structure, small volume, in light weight, simple for process, performance is good, is easy to assembling, can meet to produce
Product technology requirement.
