Abstract
The utility model discloses a valve rod two -way sealing gate valve, which comprises the following components: a valve body, a valve cove, the valve plate, valve rod and opening device, the valve body top is located to the valve gap, the fluid passage who link up the medium is seted up along axial parts to the valve body, fluid passage has water inlet and delivery port, the valve plate is located between interior water inlet of valve body fluid passage and the delivery port, valve rod one end is passed the valve gap and is connected with the valve plate, opening device is connected to the other end of valve rod, pass through gland between valve rod and the valve gap, gland lock nut, pack and press the cover sealed, still be equipped with the packing box between gland and gland lock nut. The utility model discloses a gate valve is equipped with the packing box between gland and gland lock nut, it has had two -way sealing to make between valve rod and the valve gap, after the seal wear between valve body filler and the valve rod leaks, can be sealed through the way of the second between gland and the gland lock nut, and messenger's valve can continue to use.
Description
Technical field
This utility model is related to valve technology field, more particularly, to a kind of valve rod Double sealing throttle valve.
Background technology
Valve is the control parts in fluid delivery system, has the functions such as cut-off, regulation, water conservancy diversion, voltage stabilizing, shunting, overflow pressure relief, can be used for controlling the flowing of all kinds fluids such as empty gas and water, steam, various Korrosionsmedium, mud, liquid metals.
The species of valve is various, wherein gate valve because fluid flow resistance is little, valve opening and closing is laborsaving, action sensitivity is high, highly reliable many advantages, such as and be widely used.Typically sealed by filler pressing sleeve, gland and gland locking nut between the valve rod of gate valve and valve gap, gland is pressed on filler pressing sleeve makes filler compression generation side force make valve stem seal, after such single track is sealed in the long-time use of filler, the impact of the factors such as filler is easily worn, corrodes, aging, temperature, gradually lose compactness and lead to seepage, make seal failure, the service life of impact valve.
Utility model content
For the problems referred to above, this utility model purpose is to provide a kind of gate valve of valve rod double sealing, makes the sealing of valve rod more firm, valve service life is longer.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of valve rod Double sealing throttle valve, including valve body, valve gap, valve plate, valve rod and opening device, described valve gap is above valve body, described valve body partly offers the fluid passage of insertion medium vertically, described fluid passage has water inlet and outlet, described valve plate is in valve body fluid passage between water inlet and outlet, described valve rod one end is connected through valve gap with valve plate, the other end of valve rod connects opening device, pass through gland between valve rod and valve gap, gland locking nut, filler pressing sleeve seals, described gate valve is additionally provided with stuffing-box between gland and gland locking nut.
A kind of preferred version of the present utility model, described opening device is handwheel.
Gate valve of the present utility model, it is provided with stuffing-box between gland packing airtight and watertight padding gland and gland locking nut, make to have double sealing between valve rod and valve gap, after sealing wear between valve body filler and valve rod leaks, second sealing by stuffing-box between gland and gland locking nut, so that valve is continuing with, extend valve service life.
Brief description
Fig. 1 is this utility model valve rod Double sealing throttle valve structure chart.
Specific embodiment
In order that technological means of the present utility model and implementation are apparent to, this utility model is expanded on further with reference to specific embodiment.
Referring to Fig. 1, valve rod Double sealing throttle valve of the present utility model, main inclusion valve body 1, valve gap 4, valve plate 2, valve rod 3 and opening device 11, in the present embodiment, gate valve opening device 11 is handwheel；Described valve rod 3 lower end is connected through valve gap 4 with valve plate 2, and the upper end of valve rod 3 is connected with opening device 11.
Valve gap 4 is located at the top of valve body 1, valve body 1, the upper and lower end of valve gap 4 are respectively connected together, valve rod 3, valve plate 2 are assemblied in valve body 1, described valve body 1 partly offers the fluid passage of insertion medium vertically, described fluid passage has water inlet 12 and outlet 13, and valve plate 2 is in valve body 1 fluid passage between water inlet 12 and outlet 13；Sealed by gland 5, gland locking nut 6, filler pressing sleeve 7 between valve rod 3 and valve gap 4, filler 8 is seated in filler pressing sleeve 7, it is provided with Packing seat 9, gate valve of the present utility model in the bottom of filler pressing sleeve 7, be provided with stuffing-box 10 between gland locking nut 6 and gland 5.
Gate valve of the present utility model, it is provided with another road stuffing-box 10 between gland 5 and gland locking nut 6, seal together with having added between gland 5 and gland locking nut 6, after sealing wear between filler pressing sleeve 7 and valve rod 3 leaks, rely on the second layer sealing between gland 5 and gland locking nut 6, being continuing with of valve can be ensured, extend the service life of valve.
Of the present utility model principal character, working method and of the present utility model advantage have been shown and described above.It should be understood by those skilled in the art that; this utility model is not restricted to the described embodiments; simply principle of the present utility model described in above-described embodiment and description; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.
