Abstract
A novel hydraulic cutoff valve comprises an upper piston, a servomotor oil cylinder, a lower valve body, a valve flap, a valve rod and the like, wherein a valve cover and an oil water insulating cavity are additionally arranged between the valve body and the servomotor oil cylinder, thereby upper oil and lower oil can not communicate mutually, and oil loss and deterioration can be prevented. A transparent side wall is arranged around the oil water insulating cavity, which is convenient for observing leakage points between the oil cylinder and the valve, and the leakage points can be repaired and excluded, not only O-shaped ring seal is installed on the upper end surface and the lower end surface of the valve cover, but also rubber seal, filler sealing and filler gland bolts are installed between the valve cover and the valve rod, when the seal on the upper end surface and the lower end surface of the valve cover is damaged, and the gland bolt also can be used to press the filler, thereby guaranteeing that the cutoff valve can not stop machine and can be normally used. Two journey switches are installed on the upper surface of an oil cylinder cover, a piston rod penetrating through the cylinder cover is additionally arranged on the upper end of a piston, and a striking block is arranged on the top end and is contacted with the journey switches, which not only enables a machine room to know the valve opening and closing position, but also can realize remote control of valves such as automatic cutting exchange and the like.
Description
(1) technical field: the utility model relates to a kind of hydraulically operated stop valve.Valve kind (F16K).
(2) background technique:
The existing hydraulic pressure stop valve in market is seen Fig. 2, and its structure includes members such as valve body 1, flap 2, valve rod 3, piston 6, relay oil cylinder 7, piston 6, oil sealing 6.1 and oil inlet and outlet 7.5.There are the following problems for this structure: 1. the oil cylinder chassis 7.4 of valve body 1 usefulness relay oil cylinder 7 is as valve gap 7.4, be that both shared lids are isolated, such structure, after the cylinder dish seal ring 7.6 at chassis 7.4 and valve rod place damages, top oil cylinder hydraulic oil will the valve body below valve rod flows in and flow away with the medium (water) of pipeline, befouling environment, perhaps the water in the pipeline enters the oil storage that enters hydraulic station in the servomotor oil cylinder then and has quickened the emulsification of pressure oil in irritating and cause hydraulic oil rotten, and therefore the oil of its tens tons or up to a hundred tons scrapped.2. owing to have only nonadjustable together cylinder dish seal ring 7.6 between top oil cylinder and below valve body, will cause disorderly closedown, bring unnecessary loss to factory in case damage.3. this structure is not known the stop valve present position in machine room, opens or closes.4. this structure leakage point position that can not detect by an unaided eye can't judge that the valve stem seal place has or not leakage phenomenon, also can't prevent immediately and the loss that causes is leaked in eliminating place.
(3) summary of the invention:
The novel liquid operated globe valve that the utility model provides, solve exactly above-mentioned upper and lower profit that existing liquid operated globe valve exists directly scurry mutually logical, cylinder dish seal ring is fragile and shut down, machine room is not known valve opened and closed positions of living in, can not see problems such as looking into leakage point.The technological scheme that adopts is as follows:
Novel liquid operated globe valve, valve body, flap, the valve rod of piston, relay oil cylinder and below above comprising is characterized in that:
(a) set up valve gap at the valve body top, valve rod passes the valve gap center; Installing profit separate cavities between valve gap and relay oil cylinder, the profit separate cavities is the valve gap end face that the chassis of cavity is fixedly supported on the below by the center;
(b) bottom dress rubber seal and the sealing of top filling material between valve gap and valve rod, and dress compresses gland sealed gland nut in the profit separate cavities; Valve gap and profit separate cavities chassis, top and 1 of below valve body are adorned seal ring and valve gap lower seal on the valve gap respectively;
(c) two position limit switches of relay oil cylinder cylinder lid surface installing, the piston upper end is set up a piston rod and is passed cylinder cap, and piston rod top dress collision block contacts with position limit switch, and position limit switch is connected with the machine room circuit; Dress rod seal circle between cylinder cap and piston rod.
Can adopt transparent sidewall around the above-mentioned profit separate cavities.
The beneficial effects of the utility model:
1) increases the independent valve gap of profit separate cavities and below, can prevent that upper and lower profit from directly scurrying logically mutually, prevent that oil does not run off and goes bad.2) packing seal that dress rubber seal and available gland nut compress between valve gap and valve rod if the upper and lower seal ring of valve gap damages, also can compress filler by gland bolt, guarantees the normal use of stop valve thus.3) is communicated with machine room by piston rod collision block, position limit switch, circuit etc., not only machine room can be understood the valve opening and closing position, and telecontrol such as can realize automatically section changing.4) be transparent sidewall around the profit separate cavities, be convenient to observe the seepage of oil cylinder and valve, timely maintenance and eliminating.
(4) description of drawings:
Fig. 1 the utility model positive view;
Fig. 2 has the liquid operated globe valve positive view now.
(5) embodiment:
See Fig. 1, novel liquid operated globe valve, the valve body 1 of piston 6, relay oil cylinder 7 and below above comprising, flap 2, valve rod 3 etc. have oil sealing 7.3 between piston and relay oil cylinder; 3 of cylinder bottom and valve rods have oil sealing 7.4; Cylinder bottom has oil inlet and outlet 7.5.Circle sealing O shape circle 7.2 in having between cylinder cap 7.1 and cylinder body.
The utility model improvements:
Set up valve gap 4 at valve body 1 top, valve rod 3 passes the valve gap center; Installing profit separate cavities 5 between valve gap 4 and relay oil cylinder 7, the profit separate cavities is valve gap 4 end faces that the chassis 5.1 of cavity is fixedly supported on the below by the center, and with nut 5.4 chassis 5.1, valve gap 4 and valve body 1 top flanged surface is connected and fixed.Around the profit separate cavities is transparent sidewall 5.3, and relay oil cylinder 7 is directly fixed and is supported on the transparent sidewall.
3 bottom dress rubber seals 4.1 of valve gap 4 and valve rod and top filling material sealing 4.2, and dress compresses gland sealed gland nut 5.2 in the profit separate cavities; 1 dress of valve gap 4 and below valve body end face valve gap lower seal 4.3 is O shape circle; Seal ring 4.4 also is O shape circle on 5.1 dresses end face valve gap of valve gap 4 and profit separate cavities chassis, top.
Two position limit switches 9 of relay oil cylinder 7 cylinder lid surfaces installing, piston 6 upper ends are set up a piston rod 8 and are passed cylinder cap 7.1, and piston rod 8 tops dress collision block 10 contacts with position limit switch 9, and position limit switch 9 is connected with the machine room circuit.8 dresses of cylinder cap 7.1 and piston rod rod seal circle 8.1.
