Abstract
Disclosed is an anti-losing throttle valve, comprising a throttle valve rod, a thread sleeve, a sealing sleeve, a pressure cover, a throttle valve plate and a valve body. The throttle valve rod is arranged in the thread sleeve through screw thread; the sealing sleeve is arranged in the pressure cover; the thread sleeve is nested in the upper part of the pressure cover; the lower part of the pressure cover is joined with the upper part of the valve body; the throttle valve plate is arranged on the lower part of the throttle valve rod; the throttle valve plate is contacted with a valve base in the valve body; the throttle valve plate is in dovetail suspended joint with the throttle valve rod; a dovetail groove is arranged on the upper part of the throttle valve plate; a dovetail hook is arranged on the upper part of the throttle valve rod. The limit surface between the throttle valve plate and the throttle valve rod is increased to make the throttle valve plate not fall off, so that the throttle valve can work normally for long time without frequent replacement.
Description
One, technical field
The utility model is a kind of valve of controlling line fluid, particularly a kind of Drop-proof gate.
Two, background technique
The valve that uses at present is gate valve, connect for suspension type between restrictor bar and the flashboard, the suspension shoulder is the plane, and the confined planes between flashboard and the restrictor bar is few, the flashboard problem that comes off often occurs, cause disable gate, can't switch, often stop production and change valve, increase Master Cost, consume manpower, economic loss is serious.
Three, summary of the invention
The purpose of this utility model is a kind of Drop-proof gate of design, and its flashboard can not come off, and protects and levies the long-term proper functioning of gate.
The purpose of this utility model is achieved in that by restrictor bar, thread bush, stuffing box gland, gland, flashboard, valve body to be formed, restrictor bar is installed in the thread bush, both screw by screw thread mutually, and stuffing box gland is installed in the gland, thread die cutting cover in the gland top, the gland bottom connects with valve body top, flashboard is installed in the bottom of restrictor bar, and the valve seat in flashboard and the valve body contact, and flashboard is that the dovetail type suspension connects with restrictor bar, dovetail groove is arranged at flashboard top, and the dovetail hook is arranged at restrictor bar top.
The beneficial effects of the utility model are: flashboard is that the dovetail type suspension connects with restrictor bar, and dovetail groove is arranged at flashboard top, and the dovetail hook is arranged at restrictor bar top, confined planes between flashboard and the restrictor bar increases, and flashboard can not come off, and gate is proper functioning for a long time, do not need often to change valve, remarkable in economical benefits.
Four, description of drawings
Accompanying drawing is the utility model embodiment's a erection drawing.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is made up of restrictor bar 1, thread bush 2, stuffing box gland 3, gland 4, flashboard 5, valve body 6, restrictor bar 1 is installed in the thread bush 2, both screw by screw thread mutually, and stuffing box gland 3 is installed in the gland 4, thread die cutting cover 2 in gland 4 tops, gland 4 bottoms connect with valve body 6 tops, flashboard 5 is installed in the bottom of restrictor bar 1, and the valve seat in flashboard 5 and the valve body 6 contact, and flashboard 5 connects for the dovetail type suspension with restrictor bar 1, dovetail groove is arranged at flashboard 5 tops, and the dovetail hook is arranged at restrictor bar 1 top.Confined planes between flashboard and the restrictor bar increases, and flashboard can not come off,
During unlatching, rotate restrictor bar 1, restrictor bar 1 drives flashboard 5 and moves up, and runner is opened, and fluid passes through.When closing, counter-rotating restrictor bar 1, restrictor bar 1 drives flashboard 5 and walks downwards, stops up runner, and fluid stops to flow.
