Abstract
The utility model is related to a kind of high-performance eccentric half-ball valve.Existing eccentric half-ball valve is mainly solved in the case where long-time is not opened and closed, hardly possible is opened because of fouling, and the easily problem of sealing leak.It is characterized in that：Described valve body inner side is provided with valve seat, and the valve seat offsets to form sealing pair with flap；Pressing plate is provided with described valve seat other end, the pressing plate offsets with valve seat other end；End cap is provided with described pressing plate other end, spring is provided between described end cap and pressing plate.The automatic compensation of sealing, it is ensured that sealing surface has enough sealing effectiveness；Valve can effectively be solved because long-time does not open and close the possibility of fouling and hardly possible unlatching；There can also be good anticorrosion effect under strong corrosive environment simultaneously.
Description
Technical field
The utility model is related to a kind of valve, and in particular to a kind of high-performance eccentric half-ball valve.
Background technology
Eccentric half-ball valve is to utilize eccentric center principle, one kind that hemisphere makees rotation to reach unlatching, close around valve body center
Valve.With fluid resistance is small, simple structure, small volume, lightweight, sealed reliable, it is easy to maintenance, open and close without friction, life-span
Long the features such as.Suitable for the control containing corrosive medium fluid-transporting tubings such as slurry, a material matter and sewage disposal, power station water
Control valve, reservoir dam bottom atmospheric valve, steel mill blast furnace unloading valve, cement plant ash discharge, residual cake valve, alumina industry, aluminum oxide before wheel
The various bad working environments conditions such as slurry specialty valve.
Usual eccentric half-ball valve corrosion resistance is poor, and valve damage is easily caused in the environment of deep-etching, meanwhile, valve
In the case where long-time is not opened and closed, difficult because of fouling can open.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of high-performance eccentric half-ball valve, mainly solves
Existing eccentric half-ball valve is difficult because of fouling to open in the case where long-time is not opened and closed, and the easily problem of sealing leak.
The technical scheme that the utility model is used is：A kind of high-performance eccentric half-ball valve, including valve body, bonnet and position
In valve rod is provided with the actuator on top, described valve body, valve rod upper end connection actuator, valve rod lower end is connected with flap, institute
The flap stated is eccentric semi-spherical flap, and described valve body inner side is provided with valve seat, and the valve seat offsets to form sealing pair with flap；It is described
Valve seat other end at be provided with pressing plate, the pressing plate offsets with valve seat other end；End is provided with described pressing plate other end
Lid, spring is provided between described end cap and pressing plate.
Further, described end cap is helicitic texture, and valve body inner side is provided with the screw thread worked in coordination with the end cap.
Further, described flap and the valve seat portion of contacting with each other are corrosion resisting alloy.
Further, on the corrosion resisting alloy on the flap and flap and valve seat corrosion resisting alloy and the company of valve seat
Mode is connect for built-up welding.
Further, described corrosion resisting alloy is corrosion-resistant stainless steel.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, the automatic compensation of sealing, it is ensured that sealing surface has
Enough sealing effectiveness；Valve can effectively be solved because long-time does not open and close the possibility of fouling and hardly possible unlatching；Simultaneously can also be
There is good anticorrosion effect under strong corrosive environment.

Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, a kind of high-performance eccentric half-ball valve, including valve body 1, bonnet 2 and superposed execution
Device 3, is provided with valve rod 4 in described valve body 1, the upper end of valve rod 4 connects actuator 3, and the lower end of valve rod 4 is connected with flap 5, described valve
Valve 5 is eccentric semi-spherical flap, and the described inner side of valve body 1 is provided with valve seat 6, and the valve seat 6 offsets to form sealing pair with flap 5；It is described
The other end of valve seat 6 at be provided with pressing plate 7, the pressing plate 7 offsets with the other end of valve seat 6；Set at the described other end of pressing plate 7
Have end cap 8, be provided with spring 9 between described end cap 8 and pressing plate 7, described end cap 8 is helicitic texture, the inner side of valve body 1 be provided with
The screw thread that the end cap 8 is worked in coordination.The automatic compensation of sealing, the rear end of valve seat 6 is provided with spring 9, ensures that sealing surface has enough pretensions
Power, during valve use during sealing wear, in the presence of spring 9, valve continues to ensure excellent sealing, and valve opening wink
Between can compression spring 9 give the buffering of valve seat 6 one, hemisphere and valve seat 6 is departed from less torque smooth opening valve rapidly.Energy
Effectively solve the valve possibility that hardly possible is opened because long-time does not open and close fouling.Meanwhile, when sealing pair is damaged, take end cap 8 apart
I.e. replaceable or maintenance sealing pair, very facilitates, it is not necessary to scraps whole deck valve door, increased the service life of valve.
Described flap 5 is corrosion resisting alloy with the portion of contacting with each other of valve seat 6.Corrosion resisting alloy and valve on the flap 5
Corrosion resisting alloy and the connected mode of valve seat 6 on valve 5 and valve seat 6 are built-up welding.Corrosion resistant described in described corrosion resisting alloy
Erosion alloy is specially from rare-earth element modified stainless steel, and material detailed content is referring to Chinese patent
CN200410041193.1, with more preferable anticorrosion effect.And hemisphere otch can eliminate fouling and debris etc., make valve smooth
Open and close, thus be particularly well-suited to waste residue, coal dust, containing the medium such as particle or fiber.
Every technical staff's notice：Although the utility model is described according to above-mentioned specific embodiment, this
The invention thought of utility model is not limited to that utility model, and the repacking of any utilization inventive concept will all include this specially
In sharp scope of patent protection.
