Abstract
The utility model relates to a valve, in particular to a sealing gate valve provided with parallel double gate plates, and mainly solves the technical problem that a valve structure is complex, the manufacturing cost is higher, the valve is inconvenient to open and close, the service life is shorter, and the like in the prior art. The sealing gate valve comprises a valve body (1) and is characterized in that two gate plates (2) are symmetrically arranged in the valve body (1); a wedge block (3) is clamped between the upper ends of the gate plates; the wedge block is connected with a valve rod (4); a valve deck (6) is connected to the upper end of the valve body; a support (7) is fixed at the upper end of the valve deck; the valve rod penetrates through the valve deck, and the upper end of the valve rod is connected with a hand wheel (8); the upper end of the valve deck is further connected with a packing gland (13) through a swing bolt (5); the packing gland is pressed with a packing bushing (14); an inclined surface is arranged at the upper end of the packing bushing; and packing (15) and a packing seat (6) are arranged below the packing bushing.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of sealing parallel double-flashboard gate valve.
Background technique
Valve is controlling component in the pipeline fluid transporting system, and it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve of controlling for fluid, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of the ultralow temperature to 1430 of-269 ℃ ℃.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetic driven, electricity surge, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, valve relies on and drives or automechanism makes it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is controlled function to realize it.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
The model utility content
The utility model is to provide a kind of sealing parallel double-flashboard gate valve, and it is mainly that to solve the existing valve mechanism of prior art comparatively complicated, and manufacture cost is higher, opens and closes comparatively inconvenience, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Sealing parallel double-flashboard gate valve of the present utility model, comprise valve body, be symmetrically arranged with two shoe brake plates in described valve body, be connected with wedge-shaped blocks between the upper end of flashboard, wedge-shaped blocks is connected with valve rod, the upper end of valve body is connected with valve gap, the valve gap upper end is fixed with support, the valve rod cross-under in support and upper end be connected with handwheel, the valve gap upper end also is connected with hold-down grid by swing bolt, hold-down grid compresses filler pressing sleeve, and the filler pressing sleeve upper end is provided with inclined-plane, and condiment gland below is provided with filler, Packing seat.
As preferably, the described valve rod upper end Stem Mut that has been threaded, the Stem Mut outside is provided with bearing support, is provided with bearing in bearing support, and bearing support is provided with lubricating cup.
Therefore, valve mechanism of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and more for convenience, it is comparatively easy to open and close in processing, and working life is higher.
The accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the sealing parallel double-flashboard gate valve that this is routine, as Fig. 1, comprise valve body 1, be symmetrically arranged with two shoe brake plates 2 in valve body, be connected with wedge-shaped blocks 3 between the upper end of flashboard, wedge-shaped blocks is connected with valve rod 4, the upper end of valve body is connected with valve gap 6, the valve gap upper end is fixed with support 7, the valve rod cross-under in support and upper end be connected with handwheel 8, the valve gap upper end also is connected with hold-down grid 13 by swing bolt 5, hold-down grid compresses filler pressing sleeve 14, the filler pressing sleeve upper end is provided with inclined-plane, and condiment gland below is provided with filler 15, Packing seat 16.The valve rod upper end Stem Mut 9 that has been threaded, the Stem Mut outside is provided with bearing support 10, is provided with bearing 11 in bearing support, and bearing support is provided with lubricating cup 12.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
