Embodiment
As shown in Figure 1, a kind of vertical gas control balance stop valve, comprise valve body 1, the top of valve body 1 is offered C and is controlled mouth 21, be positioned at C inside valve body 1 and control mouth 21 bottom installation piston 12, plug 11 is installed on the upside of the middle part of piston 12, socket head screw 15 is installed on the downside of the middle part of piston 12, spool 2 is installed in the screw mandrel end of socket head screw 15, the lower, outer perimeter of piston 12 installs the upper end of main spring 9, the inner side of valve body 1 is positioned at piston 12 bottom and installs guide sleeve 6, the lower end of main spring 9 coordinates with the top of guide sleeve 6, spool 2 is through the middle part of guide sleeve 6, guide sleeve 6 is positioned at spool 2 periphery and cushion pad 7 is set, the inside of valve body 1 is positioned on the downside of guide sleeve 6 and arranges seal ring 4, seal ring 4 coordinates with the periphery of spool 2, A import 19 is offered in side, valve body 1 bottom, A import 19 communicates with spool 2 side, valve body 1 bottom opposite side offers B outlet 20, B outlet 20 communicates with the opposite side of spool 2.
The utility model is by controlling to enter the source of the gas that C controls mouth 21, and promote piston 12, piston 12 and spool 2 are linked together by socket head screw 15, and piston 12 is compression main spring 9 downwards, spool 2 and seal ring 4 are thrown off, realizes the unlatching of valve; After the source of the gas controlling to enter C control mouth 21 stops air feed, piston is under the effect of main spring 9, and band movable valve plug 2 again contacts with valve body 1 and seals, fluid in truncated system.
The utility model in off position time, C controls mouth 21 not air feed (0.4 to 0.8MPa), and valve is under the effect of main spring 9 power, and band movable valve plug 2 press seal circle 4 is in closed condition.
The utility model is when valve opening state, control mouth to C and pass into control pressurized gas (0.4 to 0.8MPa), pressurized gas promotes piston 12 and departs from seal ring 4 with spool 2, thus makes fluid in system flow to B outlet 20 from A import 19, completes the open function of valve.
After the utility model C when valve closing controls the control gas stopping air feed of mouth 21, valve, under the effect of main spring 9 power, promotes piston 12 and spool 2, makes spool 2 again contact with seal ring 4 and seal, make valve closing, the fluid in truncated system.
Spool 2 of the present utility model is in structural design, and spool 2 is in high-pressure medium, and overall axially loaded makes a concerted effort to be zero, otherwise will increase control piston lifting surface area, makes the long-pending change of the entirety of valve large, can affect the life-span of valve, reliability, Economy simultaneously.
The power that main spring 9 of the present utility model produces, the frictional force that can overcome between parts, will provide simultaneously and contact with seal ring 4 sealing force produced.
Spool 2 of the present utility model sealing place, because pressure is higher, have employed first ring washer 3 of one side for arc surface, improves the bearing capacity of the 4th C type circle 18.
The design's spool 2 adopts with valve body 1 and is integrally connected design, compact structure, and volume is little; Now Pneumatic valve commercially, cylinder position and main valve portion are split type connections, and volume is comparatively large, and required installing space is also larger.
The utility model is by disassembling, analyzing existing Pneumatic valve commercially, and the medium axial force suffered by its spool, due to the restriction of project organization, does not all reach complete equilibrium, and therefore same bore valve volume is relatively large, and performance and life-span reach undesirable.The design is when designing, adopt new project organization, piston 12 is increased at the two ends of valve, the size at spool 2 two ends is completely equal, therefore suffered medium axial force complete equilibrium, the power that therefore cylinder portion provides just overcomes the power of main spring 9, and it is relatively little that piston 12 can design, whole valve is also just relatively little, can reach more than 50,000 times with the performance and life-span entering valve.
Spool 2 design adopts the structure of the pressure at two ends balance of one.The design is in order to the intensity of the performance and spool 2 that improve product, and can bear higher pressure, have employed integral structure, the two ends of spool 2 are pistons 12 that size is completely equal, can the axial force that produces spool 2 of complete equilibrium high-pressure medium from face.
The utility model adopts Changable type valve seat construction, in order to ensure the Economy of valve, on-line maintenance, have employed the nonmetal seal ring 4 of Changable type, and when in the course of the work, seal ring 4 damages and can change online, also reduces maintenance cost simultaneously.
Spool 2 of the present utility model adopts direct-coupled type structure with valve body 1, in order to ensure the Economy of valve, reduces the cost of valve as much as possible, reduce the volume of valve, spool 2 and valve body 1 adopt direct-coupled type structure, reduce the installing space of valve, cost-saving.
Third gear circle 10 is installed in the bottom of installing the 2nd C type circle the 14, two C type circle 14 between described piston 12 and valve body 1.Between piston 12 of the present utility model and valve body 1, because pressure is higher, have employed the third gear circle 10 of one side for arc surface, improve the bearing capacity of the 2nd C type circle 14.
The second ring washer 5 is installed on the top of installing the 3rd C type circle the 17, three C type circle 17 between described guide sleeve 6 and valve body 1.Between guide sleeve 6 of the present utility model and valve body 1, because pressure is higher, have employed second ring washer 5 of one side for arc surface, improve the bearing capacity of the 3rd C type circle 17.
The first ring washer 3 is installed in the bottom of installing the 4th C type circle the 18, four C type circle 18 between the bottom of described spool 2 and valve body 1.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
