Abstract
A high performance hydrogen-contacting high pressure control valve comprises an annular sealing ring groove arranged on a rigid sealing ring (6), a flexible sealing ring (8) embedded into the annular sealing ring groove of the rigid sealing ring (6), a flexible graphite winding sealing ring (9) sleeved on a filler box (5), a pressure block (7) pressed on the flexible graphite winding sealing ring (9). The high performance hydrogen-contacting high pressure control valve has the following advantages: because the flexible sealing ring is added on the rigid sealing ring (6), the flexible graphite winding sealing ring (9) is added on the wall gap between the filler box (5) and the valve body, so as to form the triple seal formed by cooperating the rigid and duplex flexibility, the gas does not easily escape from the wall gap between the filler box and the valve and very good sealing effect is obtained.
Description
Technical field
The utility model relates to gas high pressure control valve field.Relate in particular to and face the hydrogen high pressure control valve.
Background technique
Existing critical hydrogen high pressure control valve mainly is made up of valve body, valve seat, valve plate, valve rod, Stuffing box, rigidity seal ring and briquetting; Valve plate is installed on the valve body through valve seat; Valve rod links to each other with valve plate, and Stuffing box is installed on the valve body, and the rigidity seal ring set is on Stuffing box; Briquetting is embedded in valve body; And be pressed on the rigidity seal ring, its deficiency is that its sealability is good inadequately, gas is prone to overflow from the wall crack between Stuffing box and the valve body.
The model utility content
The purpose of the utility model is exactly good inadequately to existing high pressure control valve sealability, and gas is prone to the deficiency from the wall crack effusion between Stuffing box and the valve body, and provides a kind of high-performance to face the hydrogen high pressure control valve.
The utility model comprises control valve, and control valve mainly is made up of valve body, valve seat, valve plate, valve rod, Stuffing box, rigidity seal ring and briquetting; Valve plate is installed on the valve body through valve seat, and valve rod links to each other with valve plate, and Stuffing box is installed on the valve body, and the rigidity seal ring set is on Stuffing box, and briquetting is embedded on the valve body; It also has flexible seal ring and Expanded graphite to twine seal ring; On the rigidity seal ring, be provided with the ring packing ring recess; Flexible seal ring is embedded in the ring packing ring recess of rigidity seal ring, and Expanded graphite twines seal ring and is enclosed within on the Stuffing box, and briquetting is pressed in Expanded graphite and twines on the seal ring.
The utility model has the advantages that: owing on rigidity seal ring 6, installed flexible seal ring additional; And place, the wall crack between Stuffing box and valve body has installed Expanded graphite winding seal ring additional; Formed the triple seal that rigidity and double flexibility match; Gas is difficult for overflowing from the wall crack between Stuffing box and the valve body, thereby has sealing effect well.
