Abstract
A balanced type difunctional hand-operated gate valve for high-pressure water descaling belongs to the technical field of design and manufacturing of hand-operated gate valves in high-pressure water descaling systems. The gate valve comprises a valve body and a valve cap; through-holes are respectively formed on a valve core, an upper end cap and a lower end cap; a bearing support is arranged in the central hole of the valve cap; and two thrust bearings are arranged in the bearing support. When in use, the gate valve is mounted among a pressure reservoir of the descaling system, a pump and a pipeline; a handwheel is twisted clockwise, so a valve rod and a threaded bushing are driven to rotate horizontally by utilizing the thrust bearings; and through the transmission of screw pairs between the valve rod and the valve core, the valve core is jointed with a seal receptacle completely. Since the through-holes are respectively formed on the valve core and the upper and the lower end caps, the gate valve is always in a conducting state, and pressure in the valve is balanced; and besides, the thrust bearings are included, and the pressure borne by the valve rod is applied to the thrust bearings, so that sliding friction of the traditional products is changed into rolling friction, and time and labor are saved when the handwheel is turned. The utility model has the advantages of simple structure, easy manufacturing, convenient maintenance, rapid opening and closing, and time and labor saving.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of hand sluice valve in the high-pressure water descaling system.
Background technique
The hand sluice valve that present Iron and Steel Enterprises in China is used in the high-pressure water descaling system of rolled shape is made up of valve body and valve gap, and upper and lower valve cup and spool are arranged in the valve body.Because existing gate valve is to realize switching manipulation in high-pressure system work, so under the high situation of valve body internal pressure, increased the frictional force of the screw pair that is used for the lifting spool, operator will expend very big strength just can pull handwheel, cause switch untimely, bring certain influence to production.In addition, because valve rod is long, run through whole valve body, complex structure is all increasing difficulty aspect manufacturing and the installation and maintenance.Therefore say that existing product is not very desirable.
Summary of the invention
At above-mentioned situation, it is flexible that the purpose of this utility model provides a kind of switch, and time saving and energy saving and safe and reliable hand sluice valve is to solve the practical problem that existing product exists.
Structure of the present utility model as shown in drawings; Form by valve body and valve gap, a valve pocket is arranged in valve body, a spool is arranged in valve pocket.In the bottom of valve pocket one sealing seat is arranged.On the top of spool one upper end cap is arranged.In the bottom of spool one lower end cap is arranged.One upper sealing ring is arranged between spool and upper end cap, a lower sealing ring is arranged between spool and lower end cap.One filter is arranged between spool and lower end cap.Spool and up and down end cap all have through hole.One valve rod is arranged on spool.One anti-rotating shaft is arranged between valve gap and spool.One bearing support is arranged in the center hole of valve gap.Two thrust-bearings are arranged in the bearing support.One bearing gland is arranged on bearing support, a guard shield is arranged on the center hole of valve gap, the top of valve rod is threaded lining.At the top of valve rod one handwheel is arranged.At the top of valve rod suit one lifting ring.Suit one guide pin bushing on the valve rod of bearing support bottom.In the import and export of medium, have flange.Use of the present utility model is that it is installed between descaling system accumulator and pump and the pipeline, is used for the flow condition of control media.Be in opening state in the use, when needs are closed, clockwise direction turns handwheel, driving valve rod and threaded bushing utilizes thrust axis to make to horizontally rotate, screw pair transmission by valve rod and valve core chamber, spool is along the anti-rotation glides downward, and the interior lifting ring of guard shield this moment also descends by the rotation of threaded bushing, fits fully until spool and sealing seat.The water passage hole that this moment, lower sealing ring was crossed valve pocket blocks MEDIA FLOW, thus throttle down.Characteristics of the present utility model are because spool upper and lower end cover tape has through hole, are on state all the time, make the valve internal pressure reach balance.Because have thrust-bearing, the pressure that valve rod is born all is applied on the thrust-bearing again, and the sliding friction of existing product is converted into rolling friction, makes to rotate handwheel and become time saving and energy saving.The sealing seat that is positioned at valve pocket bottom had both played descend position-limiting action when closed of spool, played the effect of auxiliary seal again.The utility model is simple in structure, is easy to make, and is easy to maintenance, and switch with time saving and energy saving, is a kind of desirable hand sluice valve rapidly.
