Description

A kind of ball valve being provided with flow detection mouth and Flow-rate adjustment lock function
Technical field
The utility model relates to a kind of ball valve, specifically refers to for HVAC, brewages, daily use chemicals, needs connection traffic instrument to detect flow and is regulated a kind of ball valve being provided with flow detection mouth and Flow-rate adjustment lock function of the distribution pipeline of locking flow by spool subtended angle.
Background technique
HVAC, brewage, daily use chemicals pipeline need medium distribution pipeline flowed through at branch road place carry out flow monitoring and Flow-rate adjustment locking and safety relief, prior art is adopted and is connected in series respectively for the orifice fitting of connection traffic instrument detection flow with for being regulated the ball valve of locking flow by spool subtended angle on distribution pipeline, also needs to install the safety valve for safety relief additional simultaneously; Because the Valves and Fittings related to is many, cause the construction and installation of pipeline time-consuming, material and installation cost occupy high, and therefore, prior art exists time-consuming, that cost is high problems and shortcomings.
In order to solve above prior art Problems existing, our company at first patent application Chinese utility model patent application number: " 201220736799.7 ", disclose " a kind of ball valve being provided with flow detection mouth and Flow-rate adjustment lock function ", this ball valve is in valve body, arrange ball valve core and throttle pipe, the swing handle of roating sphere spool arranges dial, valve body arranges Road narrows interface and runner interface as flow detection interface, valve body arranges the technological scheme of safety valve, a kind of ball valve being provided with flow detection mouth and Flow-rate adjustment lock function is provided, by opening and closing, flow detection mouth, Flow-rate adjustment controls, safety relief function is integrated in one, make to need the construction and installation of the pipeline of flow monitoring and Flow-rate adjustment locking to reach saving of work and time, the object reduced costs.But, this Combined ball valve also exposes a problem in actual use, be exactly ball valve body 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 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 provides the ball valve with flow detection mouth and the Flow-rate adjustment lock function ball valve core positioning and fixing structure of the main body of ball valve being carried out to a kind of more reliable performance correcting design.
The technological scheme that the utility model adopts is: a kind of ball valve being provided with flow detection mouth and Flow-rate adjustment lock function, comprise valve body, dial, safety valve and as the Road narrows interface of flow detection mouth and runner interface, it is characterized in that: after the ball valve core both sides arranged in the valve pocket of described ball valve body connect seal ring relatively, the locking nut locking and positioning be spirally connected is set by ball valve feed-water end passage side and fixes; 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: owing to carrying out correction design to the ball valve core positioning and fixing structure with the ball valve of flow detection mouth and Flow-rate adjustment lock function formerly, the feed-water end joint of 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 ball valve of the present utility model except the keying keeping original ball valve to have, flow detection mouth, Flow-rate adjustment control and safety relief are outside 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 ball valve with flow detection mouth and Flow-rate adjustment lock function being connected to the transition adapting pipe joint of different structure, add the flexibility of use.
