Abstract
The utility model disclose a valve screw metering and maintaining jacket and solves the problems that the conventional jacket cannot maintain a screw, the screw easily hurts a user and the like. The valve screw metering and maintaining jacket comprises a spare cap, a jacket, a slide block, a slide block connecting rod and a scaleplate; the side wall of the spare cap is provided with a grease nozzle; the side wall of the jacket is provided with a long hole parallel to a central shaft and is provided with scribed lines; the center of the slide block is provided with a bearing, and the side wall of the slide block is fixedly provided with an upright post; one end of the slide block connecting rod is in threaded connection with the head of a screw, and the other end of the slide block connecting rod is fixedly connected with a bearing center hole on the slide block; the jacket is sleeved outside the screw, the slide block connecting rod and the slide block; the upright post extends out of the long hole on the jacket; the other end of the upright post is fixedly provided with the scaleplate; and the scaleplate is annular and sleeved outside the jacket. The jacket can maintain a valve screw and has a function of displaying the opening of the valve, the service life of the valve can be prolonged, the valve is opened and closed flexibly, and normal production is ensured.
Description
Technical field
The utility model relates to valve in use maintained and can show valve opening to leading screw device.
Background technique
On the metering room of oil recovery factory and flow such as terminal and multi-purpose station, a large amount of control valves is installed all, the leading screw of valve stands the wind and weather surface for a long time will oxidation and rusting, usually makes the switching manipulation of valve dumb, and influence is normally used; Even leading screw can become rusty with copper sheathing and is in the same place; Be that so-called valve rust is dead; Produce this moment and can not normally carry out, also cause damage for enterprise, so the oil recovery factory all wants expensive human and material resources that leading screw is eliminated rust every year; That just often says makes leading screw, wastes time and energy and does not say the working life that has also shortened valve.On the valve leading screw, installed protecting jacket additional for this reason; Concrete is to connect a stock in the leading screw head threads, and at protected screw and stock overcoat upper jacket, stock stretches out from the circular hole of guard head then; When its aperture of changeover valve adjustment; The length that leading screw exposes valve can change accordingly, and simultaneously variation has also just taken place the stock length of stretching out the sheath circular hole, and promptly the length exposed of stock can show the aperture of valve.Though protecting jacket has played certain protection and metering effect, reduced the erosion of leading screw weather, can not maintain leading screw, of long duration, still can get rusty; Also there is unsafe factor in this sheath in addition, is easy to scrape hurt sb.'s feelings, and is also not attractive in appearance.
Summary of the invention
The purpose of the utility model provides a kind of valve leading screw metering, maintenance sheath; This sheath can carry out maintenance to the valve leading screw, has the function that shows valve opening simultaneously, can prolong the working life of valve; The assurance valve switch is flexible, ensures to produce normal operation.
For realizing the foregoing invention purpose; The technological scheme that the application adopts is: a kind of valve leading screw metering, maintenance sheath; Comprise cap, sheath, slide block, slide block connecting rod and scale fully; The sidewall that wherein is equipped with cap is provided with grease nipple, and a side that is equipped with cap is fixed on the valve handle, and opposite side is threaded with sheath; Strip hole with central axes is set on the sidewall of sheath, on the strip hole or below jacket wall on groove is set; Bearing, vertical columns on the sidewall of slide block are installed in the center of said slide block; One end of said slide block connecting rod is connected with the leading screw head threads, and the other end is fixedly connected with bearing centre hole on the slide block; Said sheath is enclosed within the outside of leading screw, slide block connecting rod and slide block, stretches out the strip hole of column from sheath, and the other end rigid rod of column, said scale is a ring, is enclosed within the outside of sheath.
The beneficial effect of the utility model: the application's valve leading screw sheath,, it is provided with grease nipple mechanism on being equipped with the sidewall of cap, can guarantee that screw mandrel is lubricated, non-corrosive through this mechanism butter of regularly on the valve screw mandrel, annotating, possessed the function of maintenance leading screw; The slide block and the slide block connecting rod that are provided with of this sheath in addition; Adopting between the two can counterrotating Placement, has promptly guaranteed slide block with the leading screw synchronous shift, thereby having guaranteed also that slide block rotates with sheath drives the scale motion; Indicate the aperture of valve flashboard, reached the purpose of metering; In sum, valve leading screw sheath of the present invention has promptly solved antirust, the maintenance problem of valve leading screw, has also had the scalar function of leading screw displacement simultaneously concurrently, and the integral body of this sheath is also very attractive in appearance simultaneously, in actual production, has certain practical value.
Description of drawings
Fig. 1 is the surface structure schematic representation of the application's valve leading screw sheath.
Fig. 2 is the sectional view of the application's valve.
Embodiment
Further is explanation below in conjunction with accompanying drawing to the application:
Combine shown in Figure 2 by Fig. 1: a kind of valve leading screw metering, maintenance sheath; Comprise cap 1, sheath 2, slide block 3, slide block connecting rod 4 and scale 5 fully; The sidewall that wherein is equipped with cap 1 is provided with grease nipple 6, and a side that is equipped with cap 1 is fixed on the valve handle, and opposite side is threaded with sheath 2; Strip hole 7 with central axes is set on the sidewall of sheath 2, on the strip hole 7 or below jacket wall on groove 8 is set; Bearing 9 is installed at the center of said slide block 3, and vertical columns 10 on the sidewall of slide block 3; One end of said slide block connecting rod 4 is connected with leading screw 11 head threads, and the other end is fixedly connected with the center hole of slide block 3 upper bearing (metal)s 9; Said sheath 2 is enclosed within the outside of leading screw 11, slide block connecting rod 4 and slide block 3, stretches out the strip hole 7 of column 10 from sheath 2, and the other end rigid rod 5 of column 10, said scale 5 is a ring, is enclosed within the outside of sheath 2.
After on the valve this sheath being installed, regularly, leading screw and copper sheathing are maintained from being equipped with the grease nipple filling butter on the cap; Had antirust function; The workman is freed from heavy beating the leading screw work, practiced thrift great amount of time, manpower and material resources, and can prolong the life-span of valve; Be connected with the scale that can move with leading screw on the additional valves leading screw, sheath rotates with valve handle, and leading screw can be subjected to displacement; Scale also carries out synchronous displacement, and the outer wall of sheath is provided with scale, and each unit scale is represented a pitch on the leading screw; Each pitch is represented the aperture of flashboard; Through the number of division of scale indication, the aperture of metering valve flashboard, thus foundation is provided for operator's accurate work; This sheath also can make the integral body of valve very attractive in appearance except that having above-mentioned functions.
