Abstract
A hand-pull type valve actuator is provided with a support cylinder, a traction cylinder is arranged in the support cylinder and is connected with a pull rod, a hand ball is arranged at the top end of the pull rod, a valve closing lock hole and a valve opening lock hole are carved on the pull rod respectively, the lower half of the traction cylinder is sleeved with an outer magnetic ring, and the outer part of the outer magnetic ring is sleeved with a seal magnetic cylinder. During the use, the support cylinder is fixed on a valve cap. The actuator adopts hand-pull and hand-press manners, the inner diameter size of the traction cylinder is 0.3 mm larger than the outer diameter of a valve seal cylinder so that the traction sleeves the outside of the valve seal cylinder to form movable fit. The support cylinder is fixed on the valve cap, so as to enable the outer magnetic ring of the traction cylinder and an inner magnetic ring on a valve rod core to attract mutually on one same horizontal line; when a valve is required to be opened, all that is needed is to slightly pull the hand ball; when the valve is required to be closed, all that is needed is to slightly press the hand ball; moreover, if locking is required in opened and closed states, all that is needed is to slightly twist and position the hand ball and the pull rod to enter into the lock holes for locking.
Description
Technical field
The utility model relates to a kind of valve supporting apparatus, more precisely is the execution utensil of the pressure self-enclosed immediate action valve of a kind of supporting surperlight type.
Background technique
The history of human existing centuries of application to valve, that uses till today mainly contains stop valve, gate valve, butterfly valve and ball valve etc. always; And the seal ring requisite lifelong accessory that always is exactly any valve.Gap sealing between the rotation of particularly static valve gap and valve rod (sealing of living), and the various valves that are sealed in HTHP, its adjustment, to change seal ring just more frequent.Though world today's new and high technology is fast-developing, is just promoting aspect the material of seal ring also, and aspect valve design, do not implementing to get rid of the excellent process of using seal ring or improving the seal ring Environmental Conditions.
Summary of the invention
The purpose of the utility model is to provide a kind of supporting hand-pulling type valve actuator that is used for the pressure self-enclosed immediate action valve of surperlight type.
In order to achieve the above object, the solution that the utility model is taked is: a kind of hand-pulling type valve actuator, and it has a shoring; Be provided with traction cylinder in the shoring; Traction cylinder is connected with pull bar, and handball is arranged on the pull bar top, is carved with respectively on the pull bar 2 and closes block of valve eye, opens block of valve eye; The traction cylinder Lower Half is with outer magnetic ring, and the outer magnetic ring outside is with envelope magnetic cylinder.
During use, shoring is fixed on the valve gap.This final controlling element taked to pull with hand by mode, the internal diameter size of traction cylinder is greater than valve closed cylinder external diameter 0.3mm, makes it be enclosed within the valve closed cylinder and lives outward and join.Shoring is fixed on the valve gap, makes the outer magnetic ring of traction cylinder and the internal magnetic ring on the valve rod fuse on same horizontal line, carry out mutual the suction-combining force; When valve need be opened, need only handball is gently drawn; Also only need when closing the handball flicking just can be realized closing; In addition, Push And Release, will be located the entering keyhole and make it locking as long as handball and pull bar are twisted a little if needed locking.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, shoring, 2, pull bar, 3, traction cylinder, 4, envelope magnetic cylinder, 5, outer magnetic ring, 6, set screw, 2-1, handball, close block of valve eye at 2-2,2-3, open block of valve eye.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done description again.
Referring to Fig. 1, a kind of hand-pulling type valve actuator, it has a shoring 1; Be provided with traction cylinder 3 in the shoring 1; Traction cylinder 3 is connected with pull bar 2, and handball 2-1 is arranged on pull bar 2 tops, is carved with respectively on the pull bar 2 and closes block of valve eye 2-2, opens block of valve eye 2-3; Traction cylinder 3 Lower Halves are with outer magnetic ring 5, and outer magnetic ring 5 outsides are with envelope magnetic cylinder 4.
Referring to Fig. 1, when valve need be opened, as long as handball 2-1 light is carried, the outer magnetic ring 5 that traction cylinder 3 bottoms are set and the adhesive strength of valve rod fuse internal magnetic ring started valve, had realized that this valve is from pressing off the startup effect of opening; When valve need be closed,, close even if realized pressing certainly as long as with three seconds of handball flicking.
