Description
Technical field
the utility model relates to a kind of valve, is specifically related to a kind of reasonable in design, function admirable, the adjustable three-flat ball valve of valve seat of good airproof performance.
Background technique
Existing common three-flat ball valve, in use because valve seat is open type block-like design, and the sealing of valve relies on the laminating of ball valve end cap and valve body end face completely and designs reserved decrement and guarantees, when having wearing and tearing or distortion after valve seat is being used a period of time, the valve seat that can only again more renew.
And the ball valve of the common three pieces type of prior art; valve is ball valve end cap and pipeline welding after dismounting; tend to exist welding deformation; when again valve is assembled after having welded; often can cannot guarantee to fit completely in the bi-side of ball valve end cap and valve body because of reasons such as pipeline distortion and welding stresses, in easily causing, leak outside and leak simultaneously; sealing is poor, and Security is not high.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, a kind of reasonable in design of research and development design, sealing is higher, and Security is good, easy to maintenance, and life cycle is long, the adjustable three-flat ball valve of valve seat having wide range of applications.
Technological scheme: in order to realize above object, the technological scheme that the utility model is taked is as follows:
The three-flat ball valve that a kind of valve seat is adjustable, it comprises: valve body, be connected to the ball valve end cap at valve body two ends, and be threaded in two valve seat supports in valve body, be arranged on respectively two valve seats in two valve seat supports, be arranged on the valve ball on valve seat, the valve rod being connected with valve ball, valve rod periphery is provided with stem bearing, between described valve body and valve rod, filler is installed, packing press ring is installed on filler, and packing press ring is provided with butterfly spring, and butterfly spring is provided with locking nut; The upper end of described valve rod and handle socket, locking nut is installed on handle top;
Between described valve body and valve seat support, be provided with seal ring.
As preferred version, the three-flat ball valve that above-described valve seat is adjustable, is equipped with side sealing circle between described valve body and the end cap of both sides.
As preferred version, the three-flat ball valve that above-described valve seat is adjustable, described end cap is arranged on valve body by nuts and bolt.
The adjustable three-flat ball valve of valve seat that the utility model provides, reasonable in design, the wherein valve seat construction of belt supporting frame form design, whole valve seat is full structure of surrounding, when valve seat is when being subject to hydrodynamic pressure extruding, can effectively limit flowing of valve seat, there is certain steadiness, effectively guarantee the sealing of valve;
The adjustable three-flat ball valve of valve seat that the utility model provides, between valve seat support and valve body for being threaded, make valve seat in wearing and tearing or due to distortion seal failure in the situation that, can directly grasp the prosposition adjustable side of doing valve seat support with open-end wrench, toward in, screw, with the wearing and tearing of compensation valve seat, increase decrement, effectively adjust the leakage sealed of valve seat and valve ball joint.
The adjustable three-flat ball valve of valve seat that the utility model provides; between valve seat support and valve body for being threaded; because valve seat and valve ball are coated in valve body by valve seat support; can be because of after valve dismounting; thereby valve ball and seat portion branch tumble out impact sealing, effectively guarantee the safety of valve seat and ball;
And two Seal Design that leak outside, make valve after dismounting, can not be sealed with any impact to leaking outside in valve intermediate portion, while again assembling after standard is complete, only need pressing side-sealing circle just can guarantee to seal completely, the too many technical requirements that do not have to operator, the while is during by the ball valve end cap of four bolt-lockings and side sealing circle press seal, valve seat support has also been played to certain supporting effect, prevented from becoming flexible.
Beneficial effect: compared to the prior art the adjustable three-flat ball valve of valve seat that the utility model provides has the following advantages:
The adjustable three-flat ball valve of valve seat that the utility model provides, reasonable in design, easy for installation, sealing is high, there will not be leakage, and Security is good, safeguards and uses conveniently, has wide range of applications, and can overcome many deficiencies of prior art.
