Abstract
The utility model discloses a kind of guide type low noise flow control valve, the valve gap that is connected with valve body including valve body, it is in valve body and the valve rod in valve gap, described valve rod upper end connects handwheel, this valve rod lower end is connected by valve disc gland valve disc, it is provided with sealing structure between valve rod and valve gap, between described valve disc and valve body, is provided with low noise orifice plate sleeve.The simple in construction of this regulation valve, operational torque is little, thus easy to operate, and noise is low, flow-control is accurate.
Description
Technical field
This utility model belongs to valve technology field, particularly relates to a kind of guide type low noise flow control valve.
Background technology
It is generally required to arrange a flow control valve in supply and drain water system, for adjusting the nominal operation of flow system flow and pump
Point.Existing valve can play such effect, but, it is big to there is operational torque in it, thus operating difficulties；Flow-rate adjustment is linear
It is poor to spend, it is impossible to the accurately problem of regulation, especially in the case of low discharge, existing valve, in the moment opened or closed, is
System can produce significantly " water hammer " phenomenon, and produce bigger impact noise.
Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of guide type low noise Flow-rate adjustment
Valve, the simple in construction of this regulation valve, operational torque is little, thus easy to operate, and noise is low, flow-control is accurate.
For achieving the above object, this utility model adopts the following technical scheme that a kind of guide type low noise flow control valve,
The valve gap that is connected with valve body including valve body, being in valve body and the valve rod in valve gap, described valve rod upper end connects handwheel, this valve
Bar lower end is connected by valve disc gland valve disc, is provided with sealing structure, sets between described valve disc and valve body between valve rod and valve gap
There is low noise orifice plate sleeve.
In technique scheme, at the bottom centre of described valve disc, it is provided with guide post, is provided with in valve body and joins with guide post
The guide ring closed.
In technique scheme, between two ends and the valve body of described low noise orifice plate sleeve, it is provided with pad.
In technique scheme, described low noise orifice plate sleeve is low resistance low noise restricting orifice.
In technique scheme, filler that described sealing structure includes setting gradually from top to bottom, sealing ring, filler pressure
Lid, described filler is filled between valve rod and valve gap, is provided with O and back-up ring between described sealing ring and valve gap.
The beneficial effects of the utility model are: this regulating valve structure is simple, easy to operate；Use the double of guide post and valve disc
Guide frame, cancels compression spring, significantly reduces operational torque；The hole count of the position of valve disc and low noise orifice plate sleeve is one by one
Correspondence, by adjusting handle, controls valve rod and the position of valve disc, thus controls the flow cartridge hole count of low noise orifice plate sleeve, accurately
Regulation flow system flow；The valve linearity is good, and Flow-rate adjustment is stable, does not haves the situation of opening and closing suddenly；Low noise acoustic aperture
Sleeve-board cylinder is low pressure loss porous restriction part, and system flow resistance is low, and the pressure loss is little, all has preferably fall when big flow and low discharge
Making an uproar effect, arrange sealing ring, O, back-up ring, gland seal, the sealing property of valve is reliable and stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. valve body, 2. guide ring, 3. guide post, 4. pad, 5. valve disc, 6. low noise orifice plate sleeve, 7. valve disc pressure
Lid, 8. valve rod, 9. valve gap, 10. filler, 11. sealing rings, 12.O type circle, 13. back-up rings, 14. glands, 15. handwheels.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of guide type low noise flow control valve as shown in Figure 1, the valve gap 9 being connected with valve body 1 including valve body 1, place
Valve rod 8 in valve body 1 with valve gap 9, described valve rod 8 upper end connects handwheel 15, and this valve rod 8 lower end is by valve disc gland 7 even
It is connected to valve disc 5, is provided with sealing structure between valve rod 8 and valve gap 9, between described valve disc 5 and valve body 1, is provided with low noise orifice plate sleeve
6。
In technique scheme, it is provided with guide post 3 at the bottom centre of described valve disc 5, is provided with and guide post in valve body 1
3 guide rings 2 coordinated.
In technique scheme, between two ends and the valve body of described low noise orifice plate sleeve 6, it is provided with pad 4.
In technique scheme, described low noise orifice plate sleeve 6 is low resistance low noise restricting orifice.
In technique scheme, described sealing structure includes the filler 10 set gradually from top to bottom, sealing ring 11, fills out
Material gland 14, described filler 10 is filled between valve rod 8 and valve gap 9, is provided with O 12 between described sealing ring 11 and valve gap 9
With back-up ring 13.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.
