Abstract
The utility model discloses a manual valve which has opening indication, belonging to the field of valve technique; the valve comprises a valve body which is internally provided with a valve core which is arranged on a valve rod; the upper end of the valve rod is connected with a valve rod sleeve by a thread; the valve rod sleeve is rotatablely supported on the valve body; the valve rod sleeve is provided with a handwheel; the upper end of the valve rod sleeve is connected with a hollow thread sleeve by the thread; the upper end of the valve rod is connected with a dual-head stud by the thread; a thread section at the upper end of the dual-head stud extends into the thread sleeve; the thread section at the upper end of the dual-head stud is provided with a nut; the side surface of the thread sleeve is provided with an axial straight trough; a column-shaped pointer passes through the axial straight trough and is connected with the nut; when the handwheel is rotated, the nut is driven to rotate on the dual-head stud and the pointer will motion along the straight trough by a certain distance; by the position relation of the pointer and the straight trough, whether the position of the valve is opened or closed can be judged; therefore, the working state of the valve can be conveniently and objectively observed, the management and operation are convenient and the valve can be applied to various pipeline systems of water, oil, gas and the like.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of manually-operated gate.
Background technique
In the prior art, common manually-operated gate is as stop valve, gate valve etc., these valves mainly include valve body, are provided with spool in the valve body, and spool is installed on the valve rod, valve rod upper end screw thread is connected with valve stem casing, and valve stem casing is supported on the valve body rotationally, and valve stem casing is provided with handwheel.This valve is when work, rotate handwheel, valve stem casing and valve rod relatively rotate, the pulling spool moves up and down, and spool moves and makes opening of valves or close, and existing manually-operated gate does not have the aperture indicating device more, when using, the user opens or closes with feeling usually, do not fit badly, open deficiency or over-open exactly, make troubles to management.
The model utility content
The purpose of this utility model provides a kind of manually-operated gate with aperture indication, makes valve opening have indication, so that operation.
The purpose of this utility model is achieved in that the manually-operated gate with aperture indication, includes valve body, is provided with spool in the valve body, spool is installed on the valve rod, valve rod upper end screw thread is connected with valve stem casing, and valve stem casing is supported on the valve body rotationally, and valve stem casing is provided with handwheel; Valve stem casing upper end screw thread is connected with the thread bush of a hollow, valve rod upper end screw thread is connected with a stud, the thread section of stud upper end stretches in the thread bush, the thread section of described stud upper end is provided with a nut, the thread bush side offers an axial straight trough, and a column pointer passes axial straight trough and is connected with described nut.
During the utility model work, thereby rotation handwheel actuatable valve bar rises or descends valve opening or cuts out, when handwheel rotates, thread bush rotates with handwheel, the thread bush push pointer is rotated, pointer drives nut and rotates on stud, make nut also on stud, rotate, because pitch is unequal in pitch on the stud and the valve stem casing, making that pointer can be along the straight trough certain distance that moves, thereby can judge the residing position of valve by the position relation, be to open or close, for making things convenient for indicating positions, the corresponding direction board that is provided with valve opening and closed position on the described thread bush.Compared with prior art, the utility model can be observed the working state of valve easily and intuitively, has made things convenient for management and operation, and it can be applicable in the pipe-line system such as various water, oil, gas.
For reducing the height of thread bush, described thread bush top is provided with center hole, and insert in the center hole upper end of stud.At opening of valves or when closing, stud can stretch out or withdraw in the center hole, like this, can reduce the height of thread bush.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to partial view.
Wherein, 1 thread bush, 2 pointers, 3 axial straight troughs, 4 stud, 5 direction boards, 6 handwheels, 7 valve stem casings, 8 valve rods, 9 valve bodies, 10 nuts, 11 center holes.
Embodiment
As figure, have the manually-operated gate of aperture indication, include valve body 9, be provided with spool in the valve body 9, spool is installed on the valve rod 8, and valve rod 8 upper end screw threads are connected with valve stem casing 7, and valve stem casing 7 is supported on the valve body 9 rotationally, and valve stem casing 7 is provided with handwheel 6; Valve stem casing 7 upper end screw threads are connected with the thread bush 1 of a hollow, valve rod 8 upper end screw threads are connected with a stud 4, the thread section of stud 4 upper ends stretches in the thread bush 1, the thread section of described stud 4 upper ends is provided with a nut 10, thread bush 1 side offers axial straight trough 3, one column pointers 2 and passes axial straight trough 3 and be connected with described nut 10; The corresponding direction board 5 that is provided with valve opening and closed position on the thread bush 1; Thread bush 1 top is provided with center hole 11, and insert in the center hole 11 upper end of stud 4.
Claims (3)
1. have the manually-operated gate of aperture indication, include valve body, be provided with spool in the valve body, spool is installed on the valve rod, and valve rod upper end screw thread is connected with valve stem casing, and valve stem casing is supported on the valve body rotationally, and valve stem casing is provided with handwheel; It is characterized in that: valve stem casing upper end screw thread is connected with the thread bush of a hollow, valve rod upper end screw thread is connected with a stud, the thread section of stud upper end stretches in the thread bush, the thread section of described stud upper end is provided with a nut, the thread bush side offers an axial straight trough, and a column pointer passes axial straight trough and is connected with described nut.
