Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
A kind of axial flow gas control balance stop valve, as shown in Figure 1, comprise housing 2, the inner side of housing 2 arranges valve component 1, the side of valve component 1 arranges B outlet 10, the opposite side of valve component 1 installs movable valve seat 4, in movable valve seat 4, moving valve 11 is installed, moving valve 11 side arranges tieing 8, the end of tieing 8 arranges sealing gasket 5, tieing 8 is coordinated with moving valve 11 by sealing gasket 5, the inner side of tieing 8 arranges flow controller 17, tieing 8 is positioned at flow controller 17 side and A import 16 is set, Returnning spring 7 is set between movable valve seat 4 and housing 2, the side of spring 7 coordinates with housing 2, the opposite side of spring 7 coordinates with movable valve seat 4, housing 2 arranges piston 3 between valve component 1 and movable valve seat 4, housing 2 is positioned at spring 7 top and C control mouth 18 is set.The utility model by controlling source of the gas, promotes piston 3 and movable valve seat 4 Compress Spring 7 in use, moving valve 11 and sealing gasket 5 is thrown off, realizes the unlatching of valve; After control source of the gas stops air feed, movable valve seat 4, under the effect of spring 7, again contacts with movable valve seat 4 and seals, fluid in truncated system.
As shown in Figure 1, shown position is that C controls mouth 18 not air feed (0.4 to 0.8MPa), and moving valve 11 is in closed condition under the effect of spring 7 power.
The first, valve opening: control mouth 18 to C and pass into control pressurized gas (0.4 to 0.8MPa), pressurized gas promotes piston 3 and departs from sealing gasket 5 with moving valve 11, thus make fluid in system flow to B outlet 10 from A import 16, complete the open function of moving valve 11.
The second, after valve closing: C controls the control gas stopping air feed of mouth 18, moving valve 11, under the effect of spring 7 power, promotes movable valve seat 4 and piston 3, makes movable valve seat 4 again contact with sealing gasket 5 and seal, moving valve 11 is closed, the fluid in truncated system.
The design of movable valve seat 4, in structural design, movable valve seat 4 is in high-pressure system, and axially loaded makes a concerted effort to be zero, otherwise will increase piston 3 lifting surface area, makes the long-pending change of the entirety of moving valve 11 large, can affect the life-span of moving valve 11, reliability, Economy simultaneously.Meanwhile, movable valve seat 4 wants to reach axial pressure and completes balance, design pressure equalizing orifice.The design of spring 7, the power that spring 7 produces, the frictional force that can overcome between parts, will provide simultaneously and contact with sealing gasket 5 sealing force produced.
The design adopts axial flow to design, compact structure, and required installing space is little.Now stop valve commercially, valve seat is all fixed, and the design adopts the movable valve seat 4 of band equalizing orifice, and the life-span is long, opens and closes sensitive, reliable.
