Abstract
The utility model discloses a kind of pneumatic ball valve valve ball for water process, including ball valve body (2), ball valve centre bore (3) and discharge orifice (4), the ball valve centre bore (3) and discharge orifice (4) vertical connection are offered on the ball valve body (2)；Wherein, the aperture of the discharge orifice (4) is 1/5th of the aperture of the ball valve centre bore (3).The utility model low cost, it is only necessary to common ball valve, can be achieved on valve ball by machining perforate.And the utility model Stability Analysis of Structures, bigger pressure can be resistant to compared to regulating valve ball valve.
Description
Technical field
It the utility model is related to a kind of pneumatic ball valve valve ball for water process.
Background technology
In clean water treatment field, the especially module device such as pure water water dispenser, because equipment is more complicated, have identical
Operating condition.In different operating conditions, it may be desirable to different pipe flow speeds and pressure.
At the concentrated water side drainage pipeline of RO (counter-infiltration) water dispenser, pressure ratio is higher (usual 10bar or so), while in order to
The discharge capacity of water is reduced, it is necessary to the vent valves of ball valve be reached very small.
Traditional method has two kinds：One kind is using pneumatic or electric control valve, and when needing low discharge, regulating valve is opened
Degree reduces.But the defects of this way, is, regulating valve it is costly, it is less economical, and be for a long time in regulating valve small
The service life of regulating valve can be impacted under aperture, increase operating cost.
Second is to add restriction orifice after control valve.Control valve opening is too low when this can solve low discharge asks
Topic, but when concentrated water side carries out big yield flushing (big flow), because flow velocity is very high, very big noise can be produced.
Utility model content
The purpose of the utility model is that a kind of pneumatic ball valve valve for water process is provided the defects of presence for prior art
Ball.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of pneumatic ball valve valve for water process
Ball, including ball valve body 2, ball valve centre bore 3 and discharge orifice 4, the He of ball valve centre bore 3 are offered in the ball valve body 2
The vertical connection of discharge orifice 4；Wherein, the aperture of the discharge orifice 4 is 1/5th of the aperture of the ball valve centre bore 3.
The beneficial effects of the utility model：
1st, the utility model low cost, it is only necessary to common ball valve, can be achieved on valve ball by machining perforate.
2nd, the utility model Stability Analysis of Structures, bigger pressure can be resistant to compared to regulating valve ball valve.
3rd, the utility model applicability is wide, according to actual different flow/pressure condition, can select different size of let out
Discharge orifice.Even if later service condition changes, it is only necessary to valve ball is changed, without changing whole valve.
4th, the utility model is noiseless, function during big flow using ball valve in itself, no extra noise.
Brief description of the drawings
Fig. 1 is main view schematic diagram of the present utility model.
Fig. 2 is left view figure structure schematic representation of the present utility model.
Embodiment
Shown in Fig. 1, Fig. 2, it is related to a kind of pneumatic ball valve valve ball for water process, including ball valve body 2, the ball valve master
Ball valve centre bore 3 and discharge orifice 4, ball valve centre bore 3 and discharge orifice 4 vertical connection are offered on body 2.
When valve opening, function is identical with conventional pneumatic ball valve.When the valve is closed, the discharge orifice 4 on valve ball is still
Water can be allowed to flow through.And the size of discharge orifice can be easy to be adjusted by machining；According to the flow being actually needed not
Together, different size of discharge orifice can be selected.Generally preferably, the aperture of the discharge orifice 4 is the hole of the ball valve centre bore 3
/ 5th of footpath.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
