Abstract

The utility model relates to a timing automatic-closing valve which can automatically close in definite time after the utility model is opened. A mechanical timer is arranged on an on-off valve, the valve core of which can realize 90 DEG rotation. A valve rod penetrates through the mechanical timer and is used as the power output shaft of the mechanical timer. The timing automatic-closing valve can be timed by the mechanical timer to close automatically after the timing automatic-closing valve is opened. The utility model is safe and labor-saving.

Description

Timing automatic-closing valve

The utility model relates to a kind of valve, belongs to timing automatic closing valve.

At present, the installation and control valve is used for switch control on the transfer line.General control valve is realized opening and closing by manual control valve upper handle, and it can not realize that timing automatic closes, and gives in the work like this and brings inconvenience; When the pipeline aneroid, people wait liquid to opening of valves sometimes, when people do not do other thing waiting observation in this process, may cause future trouble when waiting liquid, bring very big trouble to people again.

It is not enough that the purpose of this utility model is to avoid in the above-mentioned prior art, and the timing automatic when a kind of selecting is provided is closed (cock-type) valve, can realize that timing automatic closes by select time, and control is convenient, can not cause future trouble.

The purpose of this utility model can reach by the following technical programs: be combined with mechanical timer on the cock-type valve body, valve rod passes and as the pto of timer this purpose in fact.

The utility model can have following effect than above-mentioned present technology: timer is housed on the valve, can realizes regularly closing, can not cause future trouble, save manpower simultaneously, and safe and reliable.

Fig. 1, the 2nd, the utility model master, left view;

Fig. 3, the 4th, the utility model adopt master, the left view of another kind of valve core.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

Shown in Fig. 1,3, revolve to turn 90 degrees on the cock-type valve 1 that can realize switch at valve rod 12 mechanical timer 11 is housed, valve rod 12 is worn timer and is made the pto 12 of timer, can realize regularly closing.

Adopting valve core 3 is ball or cone-shaped cock-type valve 1, and valve rod 12 revolves to turn 90 degrees can realize switch; It has rectangular through hole valve body, and an end is for coming the liquid nose end, and the other end is the fluid nose end, and the valve core place is equipped with the jump ring 5 that nylon valve port 2, one sides are equipped with ring baffle 4 and fixed dam in the valve body.The above-mentioned timer that combines with valve can make valve body system one plane and 10 assemblings of timer base plate in advance, and with screw 9, packing ring combines.After valve rod passed the center hole of timer, rod end was equipped with rotating handle 13, fixed with nut 15, packing ring 14; Simultaneously on rod end, be inserted with rotating position pin 17, positioning column 16 nearby is housed on the timer body.Scheming in addition to go up (6,7) is valve rod upper pressing cap 7 and filler 6.

Claims

1, a kind of revolving at valve core turn 90 degrees the timing automatic closing valve that constitutes on the valve that can realize switch, it is characterized in that: mechanical timer (11) is housed on the valve body, and valve rod (12) passes and as the pto of timer.
