(3) utility model content
The purpose of this utility model provides a kind of electrostatic prevention spinner-type flowmeter, solve the problem that the user can't read the corresponding scale in rotor present position fast; And solve spinner-type flowmeter and inhale on flowtube because of static can make float, can influence the problem of the accuracy of the precision of measurement and adjusting then.
The purpose of this utility model is achieved in that this electrostatic prevention spinner-type flowmeter, the flowtube that comprises a back taper tubular in the shell, in this flowtube rotor is arranged, the upper end of flowtube is connected with last gas circuit integrated package through last O-ring seal, the lower end of flowtube is connected with following gas circuit integrated package through lower seal, gas circuit one end in the last gas circuit integrated package is communicated with flowtube, the other end is communicated with air outlet adapter, gas circuit in the following gas circuit integrated package respectively with flowtube, inlet suction port, flow regulator and gas circuit safety valve are communicated with, it is characterized in that: the side of above-mentioned rotor has at least two with respect to axis symmetry and the skewed slot that tilts with respect to airflow direction in the flowtube, and above-mentioned flowtube inwall is fixed with the electrostatic prevention object.
Above-mentioned rotor is a top in shape, and skewed slot is opened in the rotor upper side.
The bottom of above-mentioned rotor is a top in shape, and top is reverse frustoconic, and above-mentioned skewed slot is opened the rounding platform side on rotor top.
Be connected by a neck post between the top of above-mentioned rotor and the bottom.
The folded angle of airflow direction is 10 °-80 ° in above-mentioned skewed slot and the flowtube.

The utility model is compared with existing conventional art has following characteristics and beneficial effect:
1), because the rotor side surface in the flowtube has at least two with respect to axis symmetry and the skewed slot that tilts with respect to airflow direction in the flowtube, make rotor can not stop rotation, the user is easy to distinguish its position, has accelerated the speed of reading, and has improved the precision of reading.
2), the inwall of the utility model flowtube has also been taked antistatic countermeasure, as anti-static coating or the inner pre-buried nuditing wire of tube wall, static can be derived, thereby can eliminate the static of rotation float, prevent to inhale on flowtube, can guarantee the precision measured and the accuracy of adjusting because of static makes float.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: gas circuit, 16-shell under the gas circuit under 1-inlet suction port, 2-flow regulator, the 3-on gas circuit integrated package, 4-lower seal, 5-rotor, 5.1-top in shape, 5.2-reverse frustoconic, 5.3-neck post, 6-skewed slot, 7-flowtube, the last O-ring seal of 8-, the last gas circuit integrated package of 9-, 10-air outlet adapter, 11-gas circuit safety valve, 12-electrostatic prevention object, 13-tinsel, the last gas circuit integrated package of 14-, the 15-on the gas circuit integrated package.
(5) embodiment
Embodiment is referring to shown in Figure 1, this electrostatic prevention spinner-type flowmeter, the flowtube 7 that comprises a back taper tubular in the shell, rotor 5 is arranged in this flowtube, the upper end of flowtube 7 is connected with last gas circuit integrated package 9 through last O-ring seal 8, the lower end of flowtube 7 is connected with following gas circuit integrated package 3 through lower seal 4, gas circuit 14 1 ends in the last gas circuit integrated package are communicated with flowtube 7, the other end is communicated with air outlet adapter 10, gas circuit 15 in the following gas circuit integrated package respectively with flowtube 7, inlet suction port 1, flow regulator 2 and gas circuit safety valve 11 are communicated with, it is characterized in that: the side of above-mentioned rotor 5 has at least two with respect to axis symmetry and the skewed slot 6 that tilts with respect to airflow direction in the flowtube, the folded angle of airflow direction is 10 °-80 ° in skewed slot and the flowtube, is preferably 30 °-60 °.
The bottom of above-mentioned rotor 5 can be top in shape 5.1, and top is reverse frustoconic 5.2, is connected by a neck post 5.3 between the top of rotor and the bottom, and skewed slot 6 is opened the rounding platform side on rotor top.
The flowtube inwall is fixed with electrostatic prevention object 12, and the electrostatic prevention object both can be the anti-static coating that is attached to the flowtube inwall; It also can be the tinsel that is embedded in the flowtube inwall.
The principle of work of the utility model spinner-type flowmeter is: air communication is crossed inlet suction port 1 and is entered flowmeter, and when regulating flow regulator 2, air-flow enters flowtube 7, by air outlet adapter 10, draws flowmeter again.Because the effect of air-flow, rotor 5 can be suspended in a certain position of flowtube, simultaneously owing to there is air communication to cross skewed slot 6 on the rotor 5, and makes rotor produce rotation.Like this after the user sets up a certain flow value, the rotation that rotor 5 will a certain levitation position not be stopped in flowtube, the float 5 that relative current buret 7 does not stop to rotate can make the user be easy to distinguish the position of float.Flowtube 7 upper and lower sides designs have the lower seal 4 of using conductive rubber to make, on O-ring seal 8, the flowtube 7 of the static that produces in the float rotary course by having electrostatic-proof function, lower seal 4 that conductive rubber is made, go up O-ring seal 8, metal gas circuit integrated package 3 down, go up gas circuit integrated package 9 and derive.The utility model flowmeter design has gas circuit safety valve 11, thereby safety valve venting release reaches the purpose of protecting flowmeter when gas circuit pressure is higher than authorized pressure.
