Technical field
The utility model relates to a kind of ball valve, specifically refers to for controlling to brewage, a kind of Combined ball valve with safety, sampling and flow control function of each node of daily chemical industry delivery line.
Background technique
Brewage, each Nodes of daily chemical industry delivery line needs to exist together setting: for opening and closing the keying valve of pipeline, for the Flow valve of regulating and controlling piping flow, for sampling the sampling cock of sampling observation, for the safety valve of safety relief, prior art adopts union, threeway or four-way pipe fitting are by above-mentioned valve string and on piping node, because the Valves and Fittings related to is numerous, cause the construction and installation of delivery line time-consuming, cost up, therefore, there are time-consuming, that cost is high problems and shortcomings in prior art.
In order to solve above prior art Problems existing, our company at first patent application Chinese utility model patent application number: " 201220667058.8 ", disclose " a kind of there is safety, sampling and the Combined ball valve of flow control function ", ball valve, sampling cock, safety valve organically combine and are integrally formed device by this Combined ball valve, and dial is provided with on the swing handle of ball-valve valve rod joint, rotate swing handle, indicated by dial and select the rotation aperture of ball valve core and fixed by positioning screwn, carry out opening and closing or Flow-rate adjustment control with this; Sampling cock is for sampling sampling observation, safety valve is used for safety relief, make a valve play the action effect of four valves simultaneously, overcome prior art and there are time-consuming, that cost is high problems and shortcomings, make the object that the construction and installation of delivery line reach saving of work and time, reduce costs.But, this Combined ball valve also exposes a problem in actual use, be exactly ball valve part structural design on there is irrational place, shown in Figure 7, the ball valve core a2 side of ball valve be rely on O-ring seal a3 and the feed-water end joint a4 that is spirally connected with valve body a1 fixing to locate, during use, with pipeline connect construct or pipeline maintenance in the threaded joint of feed-water end joint a4 and valve body a1 easily cause loosening, the sealing affecting ball valve is even damaged, and whole Combined ball valve cannot be used.
Model utility content
Technical problem to be solved in the utility model is the deficiency existed for prior art, and provide a kind of ball valve core positioning and fixing structure of the ball valve part to Combined ball valve to carry out correcting design there is safety, sampling and the Combined ball valve of flow control function.
The technological scheme that the utility model adopts is: a kind of have safety, sampling and the Combined ball valve of flow control function, the dial that the swing handle comprising ball valve, sampling cock, safety valve and ball valve is arranged above and positioning screwn, it is characterized in that: after the ball valve core both sides arranged in the valve pocket of described ball valve connect seal ring relatively, arrange by feed-water end passage side the locking nut locking and positioning be spirally connected by ball valve to fix, the feed-water end passway of described ball valve is provided with the pipe screw joint with valve body disjunctor.
Further, described locking nut is provided with notch portion by seal ring side, and notch portion and seal ring outer circumferential face are connected.
Further, described pipe screw joint is Internal Pipe Thread joint.
Further, described pipe screw joint is external pipe thread joint.
Further, the pipe screw joint of described ball valve is also connected with welded stub connection.
Further, the pipe screw joint of described ball valve is also connected with female union.
Further, the pipe screw joint of described ball valve is also connected with male connector.
With our company compared with the first patent application, the utility model has the advantage of: the ball valve core positioning and fixing structure due to the ball valve part to Combined ball valve formerly carries out correction design, the feed-water end joint of the ball valve part of Combined ball valve and valve body are connected as a single entity, ball valve core change located by the locking nut be spirally connected separately with valve body fixing, and the transition adapting pipe joint devising three kinds of different structures can be connected with feed-water end joint.Make Combined ball valve of the present utility model except the keying keeping original Combined ball valve to have or Flow-rate adjustment control, sampling sampling observation and safety relief are except the function of one, the reliability used obtains further raising, simultaneously, at the needs that actual use occasion user can connect according to pipeline, select the Combined ball valve being connected to the transition adapting pipe joint of different structure, add the flexibility of use.

Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1 ~ Fig. 3, of the present utility model a kind ofly have safety, sampling and the Combined ball valve of flow control function, the dial 4 that the swing handle comprising ball valve 1, sampling cock 2, safety valve 3 and ball valve 1 is arranged above and positioning screwn 5, it is characterized in that: after ball valve core 11 both sides arranged in the valve pocket of described ball valve 1 connect seal ring 12 relatively, arrange by feed-water end passage side locking nut 13 locking and positioning be spirally connected by ball valve 1 to fix, locking nut 13 is provided with notch portion 131 by seal ring 12 side, and notch portion and seal ring outer circumferential face are connected; The feed-water end passway of described ball valve 1 is provided with the pipe screw joint 14 with valve body disjunctor, the structure of pipe screw joint 14 can be set to Internal Pipe Thread joint or external pipe thread joint form, and the present embodiment is Internal Pipe Thread joint form.For adapting to the needs that actual use occasion pipeline connects, the transition adapting pipe joint devising three kinds of different structures is connected with feed-water end pipe screw joint, as shown in Figure 4, give a kind of be connected with welded stub connection 15 there is safety, sampling and the Combined ball valve of flow control function, when using installation, be suitable for the occasion be welded to connect with pipeline; As shown in figs. 5 and 6, sets forth a kind of Combined ball valve with safety, sampling and flow control function being connected with female union 16 and male connector 17, use when installing, be suitable for being spirally connected with pipeline the occasion be connected.The transition adapting pipe joint of described above-mentioned three kinds of different structures and the inner side at pipe screw joint 14 place of being spirally connected also are provided with O-ring seal 18, ensure that the sealing of interface.
