Description
Technical field
This utility model relates to a kind of parallel sliding gate valve, belongs to gate valve technical field.
Background technology
In various types of valves, gate valve is most widely used one.Gate valve refers to that closure member i.e. flashboard is along passage
The vertical direction of axis moves, and reaches to be turned on and off the valve of purpose.Mainly as switching on or off medium use in pipeline,
I.e. standard-sized sheet or fully closed use.General gate valve can not use as throttling, and it may be used for high temperature and high pressure, it is also possible to for low temperature
Low pressure, but the two of traditional wedge-type single shutter gate valve sealing surfaces axially have a certain degree with pipeline, i.e. two sealing surfaces
Wedgewise.The use characteristic of Wedge Gate Valves is had a major impact by the size of the angle of wedge shape flashboard, angle hour closing gate valve institute
Need power reduce, but now when pipeline causes deformation due to the change of temperature, wedge shape flashboard in valve body by wedging
Probability but increases.The flashboard of traditional Wedge Gate Valves guides and uses two guiding ribs identical with valve body body material to make position
Fixing, with valve body integral casting forming, when closing under pipeline total head difference, do not use anti abrasive hard due to guiding rib
Alloy material, frequently results in guiding rib and is very easy to abrasion and scratch, and the most serious causes jam, and valve cannot normally be transported
OK, the significant wastage of production is caused.The manufacturing procedure of single disc Wedge Gate Valves is complicated, to the required precision of sealing surface angle relatively
Height, assembling needs increase to join an operation, and the valve production cycle is the veryest long, and assembled in situ or maintenance need special oblique mould special
Instrument, adds the difficulty of field operation, and cost is significantly greatly increased.
Utility model content
Technical problem to be solved in the utility model is to provide one and can use as throttling, and valve channel flow can
The parallel sliding gate valve adjusted；Further, the present invention provides a kind of ram movement to have the parallel sliding gate valve of self-steering function；
Further, the present invention provides one to have automatic cleaning action, prevents sealing pair from being polluted by impurity such as any granules, reduces
Contact stress on sealing surface, extends the parallel sliding gate valve in valve service life；Further, the present invention provides one to exist
Under spring uniform load power effect, significant difference of hardness greatly reduces abrasion, the parallel sliding gate valve that abrasion resistance properties is good.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of parallel sliding gate valve, including valve body, is provided with valve channel in described valve body, described valve channel is arranged

The beneficial effects of the utility model: a kind of parallel sliding gate valve that this utility model provides, sealing pair leads to valve body
The setting of road central axis, making gate valve of the present utility model is upward and downward parallel slide type gate valve, thus is different from existing
Wedge Gate Valves；The external diameter of the big end of valve seat is more than the setting of height of the big end of flashboard, when making valve wide open, ram seal face without departing from
Sealing surface of seat, therefore define flashboard assembly self guide mechanism, it is simple to the folding of flashboard, it is not susceptible to fault；Under flashboard clamping plate
The boss of side blocks the draw-in groove at flashboard top, and flashboard uses anti abrasive Hardmetal materials with valve seat, at spring uniform load
Under power effect, significant difference of hardness greatly reduces sealing pair abrasion；Meanwhile, independent flashboard (i.e. two flashboards), wide flat valve
Seat (i.e. the big end of valve seat) adds upper flashboard edge chamfer, and the groups of springs of independent assortment provides suitable sealing force at any time, makes
During valve closing, flashboard and valve seat have automatic cleaning action, prevent sealing surface from being polluted by impurity such as any granules, decrease
Contact stress on sealing surface, extends valve service life.The design simple in construction, strong operability, assembling is simple, without wedge shape
Effect, sealing surface contact stress is little, under high temperature and high pressure condition, due to the discontinuous structure of valve body, spring loaded flashboard group
Part can absorb irregular thermal expansion, and compensates the irregular wear of valve seat, thus improve valve serviceability and
Extend life of valve.Assembling or maintenance just can complete without specific purpose tool.
