Abstract
The utility model relates to a fine adjustment valve. The fine adjustment valve comprises a valve seat (8), an inlet and outlet port (6), a valve core (5) and a knob (1), wherein the valve core (5) is arranged in the valve seat (8) and can rotate and selectively control the inlet and outlet port (6) to be connected or disconnected with the valve seat (8), and the knob (1) is connected with the valve core (5) and located on the outside of the valve seat (8). The fine adjustment valve is characterized in that a change gear set for slowing the rotation of the valve core (5) is disposed between the knob (1) and the valve core (5). Generally, the preferable number of gear wheels is two, and the preferable gear ratio is (1:4)-(1:2). According to the fine adjustment valve, the change gear set for slowing the rotation of the valve core disposed between the knob and the valve core, so that the structure of the fine adjustment valve is simple, and water or gas flow can be accurately controlled.
Description
Technical field
The utility model relates to a kind of fine tuning valve; Comprise valve seat and its import and export that are provided with; Also comprise being arranged on and to rotate in the said valve seat and can selectively control the spool whether intake-outlet is communicated with or breaks off with valve seat, also comprise being connected with said spool and being positioned at the knob outside the said valve seat.
Background technique
The spanner of various valves or knob all are directly directly to be connected with spool in the existing technology; On function; Only has the effect that is communicated with or breaks off import and export; So be to have brought inconvenience, to its air feed or water supply adjusting the time, need to implement fine setting and control like gas ring, water heater to the use in some sphere of lifes.
The model utility content
In view of the above deficiency of existing technology, the technical problem that the utility model will solve is:
A kind of fine tuning valve is provided, simple in structure.
For solving the problems of the technologies described above, the utility model has adopted following technological scheme:
Design a kind of fine tuning valve; Comprise valve seat and its import and export that are provided with; Also comprise being arranged on to rotate in the said valve seat also and can selectively control the spool whether import and export are communicated with or break off with valve seat; Also comprise being connected with said spool and being positioned at the knob outside the said valve seat, it is characterized in that, be provided with the speed change gear group of the spool rotation that is used to slow down between said knob and the said spool.
Above-mentioned speed change gear group comprises two gears, and one is the small gear that is connected with said knob, and another is the gearwheel that is connected with said spool, engagement interlock between said small gear and the gearwheel, and the number of teeth of said small gear is less than the number of teeth of gearwheel.As the simple deformation of speed change gear group, the combination of the number of its gear also can be for more than two.
The gear ratio of above-mentioned small gear and gearwheel is 1: 4～1: 2.General spool all need rotate 90 degree and realize that connected sum breaks off, and when 1: 4 gear ratio of employing, knob then just in time revolves and turns around.And the spool that has need rotate 180 degree realization connected sums disconnections, and when 1: 2 gear ratio of employing, knob then just in time also revolves and turns around.But according to the needs of practical application, as long as the rotation of the spool of realizing slowing down, gear ratio is not limited by above-mentioned ratio.
Above-mentioned fine tuning valve comprises also and is connected with said spool and is positioned at the rotating disc outside the said valve seat that the outer peripheral surface of said rotating disc is provided with and is used for anti-skidding convex-concave striped.Rotating disc is beneficial to the operator it is implemented low-angle rotation, is beneficial to fine setting control.
The beneficial effect of the utility model is:
Owing to be provided with the speed change gear group that the spool that is used to slow down rotates between the knob of the utility model fine tuning valve and the said spool.So this fine tuning valve is simple in structure, and can realize accurately controlling the flow of water or gas.
Description of drawings
Below in conjunction with accompanying drawing, the mode of execution of the utility model is done further detailed explanation:
Fig. 1 is that the utility model fine tuning valve has the stereoscopic schematic representation that part is analysed and observe.
Label is following among the figure:
1 knob, 2 rotating discs, 3 small gears
4 gearwheels, 5 spools 6 are imported and exported
7 passages, 8 valve seats, 9 shells.
Embodiment
Embodiment one
As shown in Figure 1, the existing fondational structure of the utility model fine tuning valve is that the valve with the ball valve type is the explanation that example is carried out, and the valve that can certainly select other types is implemented to improve as the existing fondational structure of the utility model fine tuning valve.
The utility model fine tuning valve comprises a valve seat 8 with spherical chamber; The import and export 6,6 that are provided with on valve seat 8 both sides '; In the chamber of valve seat 8, be provided with a spool spherical in shape 5, spool 5 can rotate in the chamber of valve seat 8, is provided with a passage 7 in addition in the central position of spool 5; When rotary spool 5 is 90 when spending, can selectively control passage 7 on the spool 5 whether with the import and export 6,6 on valve seat 8 both sides ' be communicated with or break off.
Fine tuning valve also comprises the knob 1 and rotating disc 2 that are connected with said spool 5 and are positioned at outside the valve seat 8, and knob 1 is vertically set in the center radial position of rotating disc 2, and the outer peripheral surface of said rotating disc 2 is provided with and is used for anti-skidding convex-concave striped.During use, be communicated with immediately or break off valve, accurately be communicated with or break off valve thereby rotating disc 2 is suitable for slow rotary spools 5 thereby knob 1 is beneficial to fast rotational spool 5.
Fine tuning valve also comprise by one by small gear 3 and one by the slow down speed change gear group of spool 5 rotations of gearwheel 4 being used to of constituting.Small gear 3 is connected with said knob 1, and gearwheel 4 is connected with said spool 5, engagement interlock between small gear 3 and the gearwheel 4, and small gear 3 is 1: 2 with the gear ratio of gearwheel 4, and small gear 3 is 10 teeth, and gearwheel 4 is 20 teeth.Through the speed change of small gear 3, can spool 5 be revolved the operation that turn 90 degrees the completion connection or break off and become, thereby realize accurately controlling spool 5 connections or disconnection valve by knob 1 or the completion of rotating disc 2 Rotate 180 degree with gearwheel 4.
Fine tuning valve comprises that also is used for the shell 9 that parts such as above-mentioned valve seat 8 and gear train are blocked.
As the simple deformation of present embodiment, small gear 3 also can be 1: 4 with the gear ratio of gearwheel 4, and small gear 3 is 10 teeth, and gearwheel 4 is 40 teeth.Can spool 5 be revolved thus and turn 90 degrees the operation that accomplish to be communicated with or to break off and become and revolve three-sixth turn by knob 1 or rotating disc 2 and accomplish, thereby realize control more accurately.
