Abstract

The utility model discloses a valve controlling communication and breaks of liquid and gas, and effectively solves the problem of large resistance of opening and closing of present valve and unreliable work. The valve comprises a valve body and a valve core. An intracavity skeleton, an elastic valve block and a switching body are provided in the valve core. Changing the position of the switching body by rotating or translation can realize communication and break of the valve. Moment of opening and closing of the valve is small, and is the half of the valve which has same specification, so the valve is very fast. Opening and closing state of upper and lower valve has no effect on opening or closing of the valve. The utility model can be extensively used for rational supply of every kind of liquid, communication and break control of gas, and communication and break control of every kind of fluid of maneuvering, manual and induced driving.

Description

Liquid, gas on-off valve

The utility model relates to a kind of valve of controlling various liquid, gas break-make.

In the modern life, various fluids (comprising water, coal gas, heating installation etc.) need rationing.Abroad, utilize the quantitative valve of smart card control to be widely used.Domestic this class valve of developing mainly is at present: the plunger valve of the gate valve that motor driving is traditional, stopcock or ball valve, solenoid-driven, because the valve opening and closing resistance of these kinds is big, thereby required driving power is bigger, and the fouling that exists in medium and the valve body often makes the work of spool unreliable.In addition, also have some manual, sensing valves commonly used to exist the problem in working life.The patent disclosure that a patent No. is arranged is 99233408x a kind of " throwing the card water meter " solved control water meter rationing tap water problem, but this water valve must cut out gate valve before the table when opening, working procedure is complicated.

The purpose of this utility model is to provide a kind of liquid, gas on-off valve of suitable multiple control modes, realizes the rationing and the break-make control of liquid, gas easily.

The purpose of this utility model is achieved in that

Liquid, gas on-off valve comprise valve body and spool, one inner chamber skeleton is arranged in the spool, an elastic element is installed on the skeleton, the skeleton inner chamber has aperture, spool comprises that also has two switching bodies that switch the hole, and two switching holes of switching on the body are corresponding with the aperture of skeleton inner chamber.Two switching holes of switching on the body also link to each other with outlet with the import of valve respectively.Switch body and can rotate or translation, driven by drive part, drive part is made of micromachine or miniature magnet or armstrong's patent parts.Rotation or translation change the position of switching body, with the corresponding hole of switching the outlet of the import of valve core cavity and valve or valve are connected.Connect when the import of valve core cavity and valve, close at the effect lower valve core of inlet fluid high pressure; Connect when the outlet of valve core cavity and valve, realize the spool unlatching.Whole spool is installed in the valve body, and drive part can be formed one with spool and also can be contained in outside the valve body.The element of controlling and driving part can be connected as a single entity with valve body also can be in external telecontrol.

The utility model is compared with similar valve, and good effect is: open and close moment little (DC3V, 150mA can drive), be 1/20 of same specification valve; Action fast (1～2 second); The keying state of upstream and downstream valve has no effect to the switching motion of this valve.This valve arrangement is simple in addition, reliable operation.

The utility model is elaborated with mode of execution below in conjunction with accompanying drawing:

As shown in Figure 1: the 2nd, valve body, the 8th, valve import, the 1st, valve outlet port; At valve inner combination valve core is housed, stifled with an elastic element 3 as valve, be installed in spool skeleton 4 bottoms, skeleton inner chamber top has two apertures 5 corresponding with two apertures 6,11 that switch on little 7 respectively, little axle 7 is driven by micromachine 10, can forward and reversely revolve and turn 90 degrees, corresponding aperture is connected valve core cavity respectively with the import 8 of valve or the outlet 1 of valve.Shown position is that valve core cavity is connected with outlet, and spool is an opening state; Otherwise, when revolving, little axle turn 90 degrees, and valve core cavity and import are connected, and close at the effect lower valve core of ingress medium high pressure.The power line 9 of micromachine 10 is drawn outside the valve body and is linked to each other with a 3V lithium cell.Actual measurement work immediate current is 120～150mA, opening of valves speed 0.8～1.2 second, closing velocity 1.0～2.2 seconds.

Claims

1, a kind of liquid, gas on-off valve, comprise valve body and spool, it is characterized in that: an inner chamber skeleton is arranged in the spool, one elastic element is installed on the skeleton, the skeleton inner chamber has aperture, spool comprises that also has two switching bodies that switch the hole, two switching holes of switching on the body can be corresponding with the aperture of skeleton inner chamber, two switching holes of switching on the body also link to each other with outlet with the import of valve respectively, switching body can rotate or translation, change the position of switching body, valve core cavity is connected with the import of valve or the outlet of valve respectively with the corresponding hole of switching.

2, the described on-off valve of claim 1 is characterized in that: the elastic element that is installed on the skeleton is that a valve is stifled.

3, the described on-off valve of claim 1 is characterized in that: the switching body in the spool is a little axle, turn 90 degrees the position that changes the switching body by forward and reverse revolving.
