Abstract
The invention discloses a kind of valve clamping nut for having leakage and blocking function, including the perisporium containing internal thread that can be engaged with the swivel nut (1) of valve, the top that centre bore can be in contact with the valve rod (2) of valve, thickening is arranged at the perisporium and top, the centre bore side is provided with annular recess (3), and the bottom surface of the perisporium is provided with several holes (4) being connected with the depression (3).Rotary hand wheel valve, after adapted clamping nut of the present invention, once, gland or filler damage in valve, from the liquid material of valve rod (2) upper spray between clamping nut, are cached through the depression (3), and by being leaked out under the hole (4), so as to avoid being sprayed onto rotary handwheel, personnel easy to operation single-handedly close to rotary handwheel, close valve in time at leisure.
Description
Technical field
The invention belongs to valve part, more specifically to a kind of valve clamping nut for having leakage and blocking function.
Background technology
A kind of existing rotary hand wheel valve, once, gland or filler damage, liquid material often from valve rod with
Rotary handwheel is sprayed onto between clamping nut, so that operating personnel are difficult to single-handedly close valve in time close to rotary handwheel, therefore,
A kind of valve clamping nut for having leakage and blocking function is provided, tool is of great significance.
The content of the invention
It is an object of the invention to provide a kind of valve clamping nut for having leakage and blocking function.
The valve clamping nut of function is blocked in a kind of tool leakage of the present invention, including can be engaged with the swivel nut of valve containing interior
Thickening, the centre bore are arranged at the perisporium of screw thread, the top that centre bore can be in contact with the valve rod of valve, the perisporium and top
Side is provided with annular recess, and the bottom surface of the perisporium is provided with several holes being connected with the depression.
The present invention can also be：
The upper surface at the top, centre bore described in ring are provided with oil sealing pool
The method have the advantages that：
Rotary hand wheel valve, after adapted clamping nut of the present invention, once, gland or filler damage in valve,
The liquid material of upper spray between valve rod and clamping nut, is cached through the depression, and by being leaked out under the hole, so as to keep away
Rotary handwheel is sprayed onto on exempting from, personnel easy to operation single-handedly close to rotary handwheel, close valve in time at leisure.
Brief description of the drawings
Fig. 1 is that a kind of bottom for having the valve clamping nut that function is blocked in leakage of the present invention regards structural representation.
Fig. 2 is cross-sectional views of the Fig. 1 along line A-A.
Fig. 3 is cross-sectional views of the Fig. 1 along line B-B.
Fig. 4 is a kind of using effect schematic diagram for having leakage and blocking the valve clamping nut of function of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of valve clamping nut for having leakage and blocking function, including can be with the spiral shell of valve
The perisporium containing internal thread that set 1 engages, the top that centre bore can be in contact with the valve rod 2 of valve, the perisporium and top are equal
There is a thickening, the centre bore side is provided with annular recess 3, and the bottom surface of the perisporium is provided with several to be connected with the depression 3
Logical hole 4.
The upper surface at the top, centre bore described in ring are provided with oil sealing pool 5.When the clamping nut is in use, described
Oil sealing pool 5 is filled with semi-drying oil, such as butter or vaseline or other colloids, between the centre bore and the valve rod 2
Gap is blocked, the liquid material of spray in prevention, partly continue on let out.
