Abstract

The utility model relates to an energy-saving ball valve which can be operated by hands. A crank 5 which is fixed with a shaft 6 is connected with a ball body 3, and a handle 12 sheathed with the shaft is matched with a ratchet pawl 16 for operation; both ends of a large tension spring 22 arranged on a supporting board 9 of a motor 15 are separately connected with the supporting board and a valve cover 7, and a stop pin 13 arranged on a circular disk 14 is matched with the ratchet pawl 16. The valve not only can be driven by the motor, but also can be operated by hands to realize switching. With the advantages of simple structure, rusting resistance, and favorable installed performance, the utility model is easy for being used with an IC card.

Description

Manual energy-conservation ball valve

The utility model relates to a kind of manual energy-conservation ball valve.

Along with extensively popularizing of IC-card technology, the IC-card water meter is used by some users.But the used water valve of these IC-card water meters all is that it has more deficiency by traditional water valve of motor direct-drive: 1, the motor power consumption is big.2, to the water quality requirement height.3, be easy to corrosion necrosis etc., be easy to cause fault and cause the IC-card water meter and can not work.4, inconsistent because of IC-card water meter and conventional water meter installation dimension, also make applying of IC-card water meter be subjected to certain limitation.

The purpose of this utility model is exactly the deficiency of mentioning in the background technique for solving, and low energy consumption that a kind of suitable IC-card water meter uses be provided, be difficult for breaking down, manual energy-conservation ball valve.

The technical solution that the utility model proposes is:

This manual energy-conservation ball valve its mainly be with the fixing crank of axle on is connected handle and the click-fit that a spheroid and axle sleeve connect and moves, the big extension spring two ends on the motor supporting plate are connected backing pin on the disk and click-fit respectively with valve gap with supporting plate.

Fig. 1: structural representation of the present utility model (A-A).

The plan view of Fig. 2: Fig. 1.

Fig. 3: the B of flanging is to view among Fig. 2.

Below with reference to drawings and Examples the utility model is done an explanation.

As shown in Figure 1 and Figure 2, the utlity model has a valve body 1 of bringing the mouth of a river 19 and water outlet 2 into, valve gap 7 is fixed on the valve body 1.Be fixedly connected with the axle bed 24 with axle sleeve 23 sockets on valve gap 7, axle 6 is positioned at axle sleeve 23 and axle bed 24, is connected a spheroid 3 that cooperates with water outlet 2 by crank 5 with little axle 4 on axle 6.Be fixed with motor 15 on the supporting plate 9 that axle sleeve 23 is fixedlyed connected and be fixed on backing pin 13 on the disk 14.On supporting plate 9, also be fixed with and ship and resell on another market 17 and ratchet 16, be connected with small extension spring 21 between this ratchet 16 and the fixing pin 20.On axle 6, connect one handle 12 by screw 11, the bending part of this handle 12 and ratchet 16 are movingly.On the flanging of valve gap 7, be provided with a stop mouth 18 (referring to Fig. 3) that cooperates with handle 12.Be provided with seal ring 8 between axle 6 and the axle bed 24.Screw 10 is solidified as a whole axle 6 and axle sleeve 23.Said disk 14 is installed on 15 in the motor, and backing pin 13 is fixed on again on the edge of disk 14.Big extension spring 22 is connected between supporting plate 9 and the valve gap 7.

When motor 15 drags disk 14 and backing pin 13 when rotating counterclockwise an angle (as 30 °), backing pin 13 is promptly thrown off with ratchet 16, small extension spring 21 spurs ratchet 16 again and throws off with handle 12, big extension spring 22 promptly spurs supporting plate 9 and clockwise rotates, drive axle 6 by screw 10 and make the spheroid of being made by rubber 3 block water outlet 2, this valve just is in closed condition.Because ratchet 16 and handle 12 are thrown off, this moment, manual function was inoperative.

When driving valve, motor 15 at first drags disk 14 and backing pin 13 clockwise rotates, backing pin 13 makes ratchet 16 get back to the working position, this moment, ratchet 16 meshed with the bending part of handle 12, handle 12 is pushed into the position of " opening " by the position of stop mouth 18 " pass ", and handle 12 drives supporting plates 9 by ratchet 16, backing pin 13 and makes screw 10 drive axle 6 and spheroid 3 leaves water outlet 2, supporting plate 9 turning anticlockwises, big extension spring 22 is tensioned again, and this valve is in opening state.Because the engagement of ratchet 16 and handle 12, by the closing or opening of manual this valve of realization, only with hand is stirred handle 12 and is got final product in the position of " pass " or " opening " of stop mouth 18 if desired.

The utility model is owing to adopt extension spring pulling supporting plate and drive the relative water outlet of spheroid by axle and close or open, cooperating of handle and ratchet and ratchet and backing pin in addition, can be with the open and close of this valve of motor driving, and again can be by manually realizing.When opening valve, kinetic energy is become potential energy; And during valve closing, make potential energy change kinetic energy into again, and can reduce the power of motor, play energy-saving and cost-reducing effect.Advantages such as that this valve also has is simple in structure, be difficult for corrosion, fault is few are easy to common pipe and cooperate and install, and also can replace gate valve before the table of conventional water meter, are fit to and the supporting use of IC-card water meter.
