Description
Technical field
the utility model relates to a kind of valve, is specifically related to a kind of reasonable in design, the three-flat ball valve of function admirable.
Background technique
In China, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Ball valve has the action of 90-degree rotation, and faucet body is spheroid, has manhole or passage by its axis.Ball valve is mainly used to make the flow direction that cuts off, distributes and change medium in pipeline, and it only need to just can be closed tightly by the operation of 90-degree rotation and very little moment of rotation, and ball valve optimum makees switch, cut-off valve uses.
But the needle-valve of prior art, structural design is reasonable not, existing common three-flat ball valve, in use needs to remove end cap, and valve seat is just in opening-wide state, easy loose loss parts, and the sealing of valve ensures by the reserved gap of end cap flange and valve body end face, when end cap and valve body gap are not or when valve seat occurs wearing and tearing or be out of shape after using, must change valve seat, cost is higher, safeguards extremely inconvenient.And the common three-flat ball valve of prior art, is connected in pipeline process in installation, because end cap need be soldered to pipeline, or is screwed onto on pipeline, often occur that end cap can not realize completely and contacting with valve body end face, cause sealing not high.Be prone to and leak outside, bad its application area that greatly limited of Security.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, sealing is high, and Security is good, easy to maintenance, the three-flat ball valve having wide range of applications.
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 three-flat ball valve 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:
A kind of three-flat ball valve, it comprises: valve body, be connected to the end cap of valve body one end, two valve seats that are arranged on valve inner, are arranged on two valve balls on valve seat, the valve rod being connected with valve ball, lower filler and upper filler are installed between described valve body and valve rod, on upper filler, packing press ring is installed, packing press ring is provided with butterfly spring, and butterfly spring is provided with gland nut; The upper end of described valve rod and handle socket, handle top is provided with locking nut;
Two valve seats of described valve inner are positioned at valve inner both sides, and one of them valve seat is near valve interior wall, another valve seat and the adjusting nut close contact that is arranged on valve inner; This structure, in the time of valve installation, there will not be loose problem, and in the time that a small amount of wearing and tearing appear in valve seat, can, by regulating adjusting nut to compensate, realize sealing.
As preferred version, above-described three-flat ball valve, described valve body both sides are respectively connected with an end cap, between described valve body and the end cap of both sides, are equipped with side sealing circle.The utility model, wherein valve body end face is processed with seal groove, is placed with side sealing circle in groove, and end cap is provided with protrusion position and matches with it.This structure, in installation, end cap is because welding or being threaded, and while causing end cap and valve body not to fit completely, gasket seal can be realized compensation sealing, thereby can avoid the phenomenon leaking outside, better tightness.
As preferred version, above-described three-flat ball valve, described handle is provided with taper knob.
Beneficial effect: compared to the prior art the three-flat ball valve that the utility model provides has the following advantages:
The three-flat ball valve 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.
Brief description of the drawings
Fig. 1 is the structural representation of the three-flat ball valve that provides of the utility model.
