Abstract
A kind of differential type pneumatic angle pedestal valve relates to a kind of pneumatic angle pedestal valve.It comprises valve body, piston, plastics cylinder bucket, Returnning spring, indicator, execution cylinder, transparent windows, piston rod, valve seat, its major technique feature is to be provided with differential moving cylinder, differential fixed piston in described valve seat, differential moving cylinder one end links to each other with differential fixed piston, and the other end links to each other with the valve seat guide head; Differential moving cylinder is provided with equalizing orifice B and communicates with the guide head balance hole A.Adopt the differential type angle pedestal valve to improve the flexibility and the tightness of valve.Also reduced the execution cylinder bore greatly, reduced the consumption of pressurized gas, as the cylinder diameter of the valve Executive Head of Φ 65 Φ 50, and controlled pressure medium is also more extensive.
Description
Technical field:
The present invention relates to a kind of pneumatic angle pedestal valve.
Background technique:
Because the switch of original angle pedestal valve leans on the active force of cylinder and spring to guarantee fully.Anti-water hammer base import medium though when pressurized air is relatively lower, open than being easier to.But when controlled pressure medium during greater than the precompression of spring, valve has just been opened, and has produced phenomenon out of control.If adopt seat to go up to be entry mode, when by the power that pressure produced of air dielectric during greater than power that air cylinder driven produced, valve just is not easy to open so.And traditional pneumatic angle pedestal valve, the Executive Head of cylinder is all very big.Cylinder diameter as the cylinder of the angle pedestal valve Executive Head of Φ 65 latus rectums is Φ 125.Comprehensively above-mentioned, traditional angle pedestal valve, the controlled medium of each valve all has tangible ceiling restriction.
Summary of the invention
The invention provides a kind of principle that adopts differential type, make valve opening flexible; And the less differential type pneumatic angle pedestal valve of execution cylinder.
The present invention is achieved by the following technical solution: a kind of differential type pneumatic angle pedestal valve, comprise valve body, piston, plastics cylinder bucket, Returnning spring, indicator, execution cylinder, transparent windows, piston rod, valve seat, its major technique feature is to be provided with differential moving cylinder, differential fixed piston in described valve seat, differential moving cylinder one end links to each other with differential fixed piston, and the other end links to each other with the valve seat guide head;
Differential moving cylinder is provided with equalizing orifice B and communicates with the guide head balance hole A.
Valve of the present invention has valve body, piston, plastics cylinder bucket, Returnning spring, indicator, execution cylinder, transparent windows, piston rod, differential fixed piston, differential moving cylinder, compositions such as general plug sealing ring, valve seat insert, valve seat guiding, balance hole A, equalizing orifice B.The diameter of the sealing surface of valve is DN1, and the diameter of differential moving cylinder is DN2, and the characteristics of this valve are: by the equalizing orifice 2 on guide head equalizing orifice 1 and the differential moving cylinder, flow into cylinder body as MEDIA FLOW fashionable (pressure of establishing medium is P) medium.Because it is motionless that differential fixed piston is fixed on the valve body, and the power on DN2＞DN1 (area of establishing DN1 is S1, and the area of DN2 is S2) valve seat is F=P (S2-S1), so pressure medium is high more,, active force is big more, produces locking phenomenon.Needed only greater than F and carry out the required power of cylinder, and conventional valve does not have differential type moving cylinder and differential type positioning piston.Directly have only valve head and valve seat to form.If power F＞P.DN1 that the cylinder of the enterprising medium of valve seat is required.And the required power F＞P.DN1 of the spring that advances medium under the valve.In sum, adopt the differential type angle pedestal valve to improve the flexibility and the tightness of valve.Also reduced the execution cylinder bore greatly, reduced the consumption of pressurized gas, as the cylinder diameter of the valve Executive Head of Φ 65 Φ 50, and controlled pressure medium is also more extensive.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
As shown in Figure 1, valve has valve body 7, piston 6, plastics cylinder bucket 5, Returnning spring 4, indicator 3, carries out cylinder 2, transparent windows 1, piston rod 8, differential fixed piston 9, differential moving cylinder 14, and general plug sealing ring 10, valve seat insert 11, valve seat 12, valve seat guide head 13, balance hole A 16, equalizing orifice B15 form.Be provided with differential moving cylinder, differential fixed piston in the valve seat, differential moving cylinder one end links to each other with differential fixed piston, and the other end links to each other with the valve seat guide head; Differential moving cylinder is provided with equalizing orifice B and communicates with the guide head balance hole A.
The diameter of the sealing surface of valve is DN1, and the diameter of differential moving cylinder is DN2, and the characteristics of this valve are: by the equalizing orifice B on guide head balance hole A and the differential moving cylinder, flow into cylinder body as MEDIA FLOW fashionable (pressure of establishing medium is P) medium.Because it is motionless that differential fixed piston is fixed on the valve body, and the power on DN2＞DN1 (area of establishing DN1 is S1, and the area of DN2 is S2) valve seat is F=P (S2-S1), so pressure medium is high more,, active force is big more, produces locking phenomenon.Needed only greater than F and carry out the required power of cylinder.If power F＞P.DN1 that the cylinder of the enterprising medium of valve seat is required.And the required power F＞P.DN1 of the spring that advances medium under the valve.In sum, adopt the differential type angle pedestal valve to improve the flexibility and the tightness of valve.Also reduced the execution cylinder bore greatly, reduced the consumption of pressurized gas, as the cylinder diameter of the valve Executive Head of Φ 65 Φ 50, and controlled pressure medium is also more extensive.
Claims (2)
1, a kind of differential type pneumatic angle pedestal valve, comprise valve body, piston, plastics cylinder bucket, Returnning spring, indicator, execution cylinder, transparent windows, piston rod, valve seat, it is characterized in that in described valve seat, being provided with differential moving cylinder, differential fixed piston, differential moving cylinder one end links to each other with differential fixed piston, and the other end links to each other with the valve seat guide head.
