Description
Technical field
The utility model is related to ball valve technical field more particularly to a kind of novel flow rate valves.
Background technology
Ball valve is mainly used for cutting off, distribute and changing in pipeline the flow direction of medium, can be closed by rotating ball valve
Close or open the circulation of medium.Existing ball-valve structure is complicated, volume is big, sphere and sealing surface are more open, not enough tightly
It gathering, leakage point is more, poor sealing, and pressure control transmission efficiency is low, after a number of uses, pulpous state, mixed flow liquid in industrial production
The media such as body, dust precipitate in pipeline, easy fouling, obstruction, the defects of fitting badly valve.
Utility model content
The purpose of this utility model is that being the defects of overcoming the prior art, and provide a kind of more compact structure, transmission effect
Rate higher, reliability, the novel flow rate valve of better tightness.
To achieve the above object, the utility model uses following technical scheme：A kind of novel flow rate regulation ball valve, including gas
Dynamic executing agency, stent, valve body；The pneumatic actuator is equipped with above the stent, lower section is fixedly connected with valve body；It is described
Valve body has the connector for medium inflow and the outlet for medium outflow and forms what is connected between connector and outlet
Passage, the valve body include valve rod, valve seat and the ball valve with valve seat cooperation able to turn on or off, and the ball valve is arranged on connector and discharge
In passage between mouthful, the valve seat is arranged on the outlet of valve body and the ball face sealing of the port of valve seat and ball valve coordinates, described
Valve rod is arranged in valve body top and valve rod upper end is drivingly connected with the pneumatic actuator, lower end is fixedly connected with ball valve.
Further, the inner wall of the valve body outlet is equipped with fixed step, and the valve seat is fixed in fixed step simultaneously
It is close to seal with fixed step.
Further, one side of the valve seat away from ball valve is equipped with baffle ring, and the baffle ring is used to be fixed the valve seat.
Further, the ball valve is half valve eccentric ball valve.
The advantageous effect of the utility model compared with prior art is：The novel flow rate valve of the utility model is held by electronic
Row mechanism driving stem is rotated around axial direction drives ball valve to rotate to realize the keying of ball valve and valve seat in valve seat simultaneously, from
And control being interconnected between outlet and connector.The utility model total is assembled on valve, compared to existing
On a straight line, there is the probability to fail in transmission efficiency higher for flow valve more compact structure, volume smaller and drive path
Smaller, ball valve are close to seal with valve seat cooperation able to turn on or off, good airproof performance, reliability higher, practical, are conducive to marketing.
Description of the drawings
Fig. 1 is the sectional view of the utility model flow valve.
In figure：It is valve body 1, valve rod 2, valve seat 3, ball valve 4, pneumatic actuator 5, stent 6, fixed step 7, baffle ring 8, logical
Road 9, connector 10, outlet 11.
Specific embodiment
In order to more fully understand the technology contents of the utility model, with reference to specific embodiment to the skill of the utility model
Art scheme is described further and illustrates.
As shown in Figure 1, a kind of novel flow rate regulation ball valve, including pneumatic actuator 5, stent 6, valve body 1.On stent 6
Side is equipped with pneumatic actuator 5, lower section is fixedly connected with valve body 1.Valve body 1 has for the connector 10 of medium inflow and for medium
The outlet 11 of outflow and the passage 9 connected is formed between connector 10 and outlet 11, valve body 1 includes valve rod 2, valve seat 3
And the ball valve 4 with 3 cooperation able to turn on or off of valve seat, ball valve 4 are arranged in the passage 9 between connector 10 and outlet 11, valve seat 3
Ball face sealing arranged on port and the ball valve 4 of the outlet 11 and valve seat 3 of valve body 1 coordinates, valve rod 2 be arranged in 1 top of valve body and
2 upper end of valve rod is drivingly connected with pneumatic actuator 5, lower end is fixedly connected with ball valve 4.5 driving stem 2 of electric operator around
Axial direction rotates while drive is fixedly connected with ball valve 4 with valve rod 2 and rotates, by controlling keying of the ball valve 4 with valve seat 3 and then reality
Existing being interconnected between connector 10 and outlet 11.
Preferably, the inner wall of 1 outlet 11 of valve body is equipped with fixation step 7, and valve seat 3 is fixed in fixed step 7 and with consolidating
Determine step 7 to be close to seal.
Preferably, one side of the valve seat 3 away from ball valve 4 is equipped with baffle ring 8, and baffle ring 8 is used to be fixed valve seat 3.
Preferably, ball valve 4 is half valve eccentric ball valve.
The novel flow rate valve of the utility model is driven simultaneously by electric operator driving stem around axial direction rotation
Ball valve rotates to realize the keying of ball valve and valve seat in valve seat, so as to control being interconnected between outlet and connector.
The utility model total is assembled on valve, compared to existing flow valve more compact structure, volume smaller and is driven road
Line is on a straight line, transmission efficiency higher, the probability smaller to fail occurs, and being close to for ball valve and valve seat cooperation able to turn on or off is close
Envelope, good airproof performance, reliability higher is practical, is conducive to marketing.
The technology contents set forth above that the utility model is only further illustrated with embodiment, in order to which reader is easier to manage
Solution, but the embodiment for not representing the utility model is only limitted to this, and any technology done according to the utility model extends or creates again
It makes, is protected by the utility model.
