Abstract
The invention relates to a manual digital control check valve. The inner wall of a sleeve is provided with a plurality of through holes with the diameters ranging from 3mm to 11.5mm from bottom to top, the through holes play the flow control effect and are evenly arranged on the sleeve wall, each circle of same round holes is identical in size, a valve flap is installed in the sleeve, the valve flap and a hand wheel are connected through a valve rod, and adjustment is convenient. The design that the valve flap and positioning hand wheel are connected through the valve rod is unique in the same field, when the valve flap moves from bottom to top, flows are increased through the round holes different in inner diameter according to the rising height of the valve flap, the higher the valve flap is, the flows are large, and on the contrary, the lower the valve flap is, the flows are decreased. The rising and descending effects of the vertically moving valve flap is achieved by turning the hand wheel on the valve, and the rising height of the valve flap and the required flows are accurately set according to a positioning caliper beside the valve flap.
Description
Technical field
The present invention relates to a kind of manual digital and control safety check.
Background technique
Traditional safety check can not manually be controlled flow, and controllability is not strong, and maintenance is inconvenient.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, and can manually control the valve of flow.The technological scheme that realizes above-mentioned purpose is as follows:
Manual digital is controlled safety check, comprise valve body one, valve body two, the interior coupling sleeve of valve body two, one side lower end of sleeve is placed on valve body one, flap is installed in sleeve, it is characterized in that: sleeve lining top circumferencial direction has several air intlets, under sleeve lining, part offers several open-works from bottom to top, the upper end connection base frame of valve body two, the upper end of pedestal connects valve gap, valve rod is arranged on flap after passing valve gap, pedestal, and the upper end of valve rod connects handwheel, and rotation band ovable valve stem and the flap of handwheel move up and down.
Preferably, between pedestal and valve rod, be provided with nut, be provided with screw thread on valve rod, valve rod is through nut, and valve rod moves up and down along the screw thread of nut.
Preferably, the open-work on sleeve is arranged according to the circumferencial direction of sleeve, and the open-work diameter of each circle circumferencial direction is identical, and the open-work diameter of axial direction is not identical, the ascending arrangement of open-work diameter from bottom to top, and the diameter of described open-work is 3-11.5mm.
Preferably, slide calliper rule are installed on pedestal, the height after kind of calliper hand wheel rotating.
Preferably, between valve gap and nut, be provided with heat insulation graphite pads or the anticorrosion phenyl tetrafluoride pad of using.
The invention solves traditional safety check and can not manually control the defects such as flow, inconvenient maintenance, and used unique valve rod in same domain, safety check not only can manually be controlled flexibly, and practicability is stronger.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.Improvement of the present invention is mainly that valve rod rises or the height of decline can be controlled, and the water or the gas that in sleeve, flow out also can be controlled simultaneously, and remaining technology is same as the prior art.
Manual digital is controlled safety check, comprise valve body 1, valve body 22, valve body 1 adopts structure of the prior art with valve body 22, the interior coupling sleeve 3 of valve body two, one side lower end of sleeve is placed on valve body 1, flap 4 is installed in sleeve, flap can move up and down along sleeve lining, the upper end connection base frame 5 of valve body 22, in pedestal with pedestal inwall adaptation be socketed with nut 6, the upper end of pedestal connects valve gap 7, valve rod 8 is through valve gap 7, after nut 6, be arranged on flap 4, on valve rod, be provided with screw thread, valve rod 8 moves up and down along the screw thread of nut 6, the upper end of valve rod connects handwheel 9, rotation band ovable valve stem 8 and the flap 4 of handwheel 9 move up and down.Between valve gap and nut, be provided with heat insulation graphite pads 10 or the anticorrosion phenyl tetrafluoride pad of using.Slide calliper rule 11 are installed on pedestal, and flap moves up and down the effect that is reached rise and fall by the hand wheel rotating on valve, more accurately sets the height of flap rising and required uninterrupted according to the positioning caliper on side.
Sleeve lining top circumferencial direction has several air intlet 3-2, the effect of air intlet 3-2 is that air is entered, increase pressure, under sleeve lining, part offers several open-work 3-1 from bottom to top, open-work on sleeve is arranged according to the circumferencial direction of sleeve, and the open-work diameter of each circle circumferencial direction is identical, and the open-work diameter of axial direction is not identical, the ascending arrangement of open-work diameter from bottom to top, the diameter of described open-work is 3-11.5mm.
In prior art, water flows in sleeve from valve body one, the application is the valve for hot environment, after valve temperature height, water can produce gas and enter in the gap between flap and sleeve, although the gap between flap and sleeve is especially little, water also can enter in sleeve by gap once in a while, in order to prevent in use that the G&W of high temperature cannot be discharged in time and in the hot environment lower Disc situation such as stuck of easily swelling, so have many apertures on flap, make to enter the water in sleeve, the open-work of gas from flap refluxes again, the water yield that the diameter control of the open-work by different heights flows out from open-work, therefore when the height difference of flap, the flow of the water flowing out from open-work is different.When flap moves from bottom to top, the height that rises and arrive according to flap, the circular hole that has different inner diameters increases flow, and more upwards flow is larger, and on the contrary, more downward, flow is less.
These are only the preferred embodiment of the embodiment of the present invention; not in order to limit the embodiment of the present invention; all within the spirit and principle of the embodiment of the present invention, any modification of doing, be equal to replacement, improvement etc., all should be included in the protection domain of the embodiment of the present invention.
