Abstract
The invention relates to a supercritical high-pressure double-flap pressure relief sewage discharge type pneumatic flow regulating valve. The supercritical high-pressure double-flap pressure relief sewage discharge type pneumatic flow regulating valve comprises a valve body, a valve seat, a valve flap, a valve rod, a valve cage and a bonnet. Multiple rows of pressure relief holes are formed in the valve cage. The total discharge amount of the pressure relief holes formed in the valve cage is the same as that of a liquid inlet. A secondary valve flap is arranged in the valve flap and is located at the central position of the valve flap, and a secondary valve seat is arranged at the central position of the valve flap. The secondary valve seat is matched with the secondary valve flap in a sealed mode. The secondary valve seat is communicated with the valve seat. The space where the secondary valve flap is located is communicated with parts of the pressure relief holes formed in the valve cage. The secondary valve flap is connected with the valve rod, and a penetrating hole only for the valve rod to penetrate through is formed in the top end of the valve flap. The supercritical high-pressure double-flap pressure relief sewage discharge type pneumatic flow regulating valve has the advantages that the medium flowing direction is changed, namely the current mode of 'high intake and low outtake' is adopted; a valve flap structure is changed into an existing double-flap structure; the pressure relief holes are added in the large valve flap, so that operating torque is decreased; the sealing performance of the valve is improved, and the service life of the valve is prolonged; the size of the valve rod and the specification of an operating device are decreased, and cost is reduced; the valve seat is changed into the detachable valve seat at present, and maintenance is convenient.

The present invention change in design MEDIA FLOW to, changed into " high in and low out " by original " low in and high out ", big valve flap increases pressure relief vent, by changing cross section to control pressure and the flow of fluid, valve opening moment is reduced relatively, can relatively reduce valve rod size, also can reduce operation equipment specification, thus saved material, reduce cost.
Described valve seat is dismountable valve seat, and described dismountable valve seat is a circular hollow disk, and its underpart is provided with the end that boss is stuck in liquid entering hole, and the outer ring of boss is provided with spirotallic gasket and is connected with valve body; The center of hollow disk is passed for valve head, and on its edge, be provided with the Sealing of joining with valve head.Described valve rod top connects spool operating mechanism, and the part be connected with spool operating mechanism on the top of valve gap is provided with upper and lower two fillers; Oil hole is provided with between upper and lower two fillers.In liquid outlet one end, the bottommost of valve body is provided with pollutant exhaust hole.
The advantage of this patent is:
(1) MEDIA FLOW is changed to former " low in and high out ", existing " high in and low out ".
(2) valve flap structure: former single valve clack structure, existing Double-clack structure.
(3) on big valve flap, increase pressure relief vent, reduce operational torque.Improve valve seal performance and used life etc.
(4) reduce valve rod size or reduce operation equipment specification, reducing costs.
(5) former valve seat welds on body, bad dismounting.Now change detachable valve seat into, easy to maintenance.
