Mode of execution:Below in conjunction with accompanying drawing the present invention is done nearly step explanation:
As shown in Figure 1, the invention provides a kind of high-pressure flat gate valve, the valve body 01 that comprises and be connected with pipeline and valve gap 02, valve body 01 forms containing space with valve gap 02, be provided with valve plate 04, spring and valve plate supporting sleeve 05 that can lifting in containing space in this containing space, valve plate 04 is arranged on the two ends of valve plate supporting sleeve 05, and valve plate 04 is imported and exported with valve body by valve seat and linked to each other, the top of valve plate supporting sleeve 05 is connected with valve rod 09 by T-shaped groove, and valve rod 09 passes valve gap 02; Thereby valve plate supporting sleeve 05 can drive valve plate 04 lifting with forming switch between valve body entrance and outlet.
Valve plate supporting sleeve 05 is provided with the hole that the valve plate 04 for two ends connects each other, and the valve plate 04 at valve plate supporting sleeve 05 two ends connects by this hole, is provided with the dish spring that valve is carried out initial sealing between two valve plates.
Dish spring 06 utilizes alignment pin 7 to link together.
At valve plate supporting sleeve 05 top valve plate locating clip 08 is set, valve plate locating clip 08 blocks the valve plate at two ends at the top, utilizes valve plate locating clip restriction valve plate axial freedom.
The top of valve plate supporting sleeve is provided with positioning hole, and stem bottom is provided with positioning shaft, is connected restriction valve plate degrees of freedom between positioning hole and the positioning shaft.
Valve body and valve seat are the integral structure of solderless contact.
Pressure valve bonnet seal place is provided with the high-density graphite packing ring.
Specifically, such as accompanying drawing 2, shown in 3, the invention provides a kind of high-pressure flat gate valve, the valve body 01 that the pipeline that it mainly comprises with the fluid levels direction flows is connected, its interior containing space that forms after above-mentioned valve body 01 is connected with valve gap 02, valve plate supporting sleeve 05 is set in the containing space, valve plate supporting sleeve 5 both sides arrange two parallel valve plates 04, between the two parallel valve plates 04 dish spring 06 and bearing pin 07 are set, valve plate 04 contacts with the sliding sealing surface of valve seat, valve plate supporting sleeve 05 can lifting in containing space, valve rod 09 bottom is connected with the T-shaped hole on valve plate supporting sleeve 05 top, top is connected with drive unit, and drive unit makes valve plate supporting sleeve 05 rise at the sliding sealing surface of valve seat by valve rod 09, fall, between fluid input and outlet, form switch.
As shown in Figure 3, valve rod 09 bottom arranges positioning shaft and cooperates with the positioning hole that valve plate supporting sleeve 05 top arranges, guarantee the coaxality of valve plate supporting sleeve and valve rod, prevent that the valve plate supporting sleeve from prolonging the fluid flow direction swing in lifting process, can guarantee the reliability of valve closing, prevent from closing and make valve plate dislocation make valve closing not tight.
Valve plate locating clip 08 is set fixes two parallel valve plates 04, valve plate 04 is in the middle of valve rod 09 lifting process middle and lower part is in two valve seats all the time, so its underpart does not need extra fixing, if but the degrees of freedom of its valve plate fluid flow direction is limited on top without the valve plate locating clip, cause so easily valve plate in opening-closing process, to come off, cause valve invalidation.
Dish spring 06 as shown in Figure 4 and the setting of bearing pin 07 can reduce the size of conventional valves valve plate, and then reduce the size of valve body, and can provide larger initial sealing power, bearing pin 07 can limit the radially degrees of freedom of dish spring 06, can make the decrement of dish spring reach maximum, the power that has guaranteed the dish spring can be applied on two parallel valve plates, can make the dish spring that valve plate is formed initial sealing.
The present invention is rational in infrastructure, and successful is beneficial in the gate valve field and applies.
