Abstract
The utility model discloses a modular change over switch, change over switch include switch knob, mechanical valve, knob fixing base, air inlet, gas outlet, limit valve and adjusting valve stem, a serial communication port, switch knob sets up on the knob fixing base, adjusting valve stem with shift knob connects, switch knob is used for opening and closing of control machinery valve, switch knob changes revolving lower time opening or the closed condition of machinery valve, and make adjusting valve stem moves in vertical direction, adjusting valve stem is rotating intercommunication corresponding during switch knob perhaps breaks off the limit valve. The utility model discloses an arrive two switching system together, can realize opening simultaneously or closing or make two valves be in different states to two kinds of different substance's break -make has been realized.
Description
Technical field
This utility model belongs to switch designs field, is specifically related to a kind of knockdown permutator.
Background technology
Traditional valve or switch often can only control the break-make of a kind of material, and in practical service environment, when needing break-make while two kinds of materials of control, traditional switch tends not to play a role, and have impact on the control of equipment ageing.
Utility model content
For in prior art control two kinds of material break-makes time existing switch limitation, this utility model provides a kind of new switch.
The technical program is by a kind of new fabricated structure mode, by the mode that limit valve is combined with mechanical switch, what realize only need to rotate a switching knob, can control gas supply simultaneously and electric current supplies two kinds, improve service efficiency for current equipment.
The permutator that this utility model provides includes switching knob, mechanical valve, the fixing seat of knob, air inlet, gas outlet, limit valve and regulating valve stem, described switching knob is arranged on the fixing seat of knob, described regulating valve stem and described shift knob connect, described switching knob is for controlling the opening and closing of mechanical valve, what described switching knob changed described mechanical valve when screwing off is turned on or off state, and making described regulating valve stem move at vertical direction, described regulating valve stem connects accordingly when rotating described switching knob or disconnects described limit valve.
Preferably, described limit valve is positioned at the bottom of described mechanical valve, the described spacing valve rod described mechanical valve of traverse.
Preferably, described limit valve is arranged at the middle part of described mechanical valve.
According to the difference that concrete valve position is arranged, it is possible to achieve when mechanical valve is opened, limit valve is closed or connects; When mechanical valve is closed, limit valve connects or cuts out.
This utility model is by arranging two switches together, it is possible to achieve opens simultaneously or closes or makes two valves be in different states, it is achieved thereby that the break-make of two kinds of different materials.

Detailed description of the invention
The following is embodiment of the present utility model, it is used only as and illustrates rather than restriction for of the present utility model.
Referring to Fig. 1-3, there is provided herein a kind of switching device that can simultaneously realize controlling the on off operating mode of two kinds of different valves, by controlling the on off state of different valve, and then realize the control for different materials.
The switching device that the present embodiment provides includes switching knob 1, mechanical valve 4, seat 2 fixed by knob, air inlet 7, gas outlet 3, limit valve 6 and regulating valve stem 5, described switching knob 1 is arranged on the fixing seat 2 of knob, described regulating valve stem 5 and described switching knob 1 connect, described switching knob 1 is for controlling the opening and closing of mechanical valve 4, what described switching knob 1 changed described mechanical valve 4 when screwing off is turned on or off state, and make described regulating valve stem 5 move at vertical direction, described regulating valve stem 5 connects accordingly when rotating described switching knob 1 or disconnects described limit valve 6.
In device as shown in Figure 2, described limit valve 6 is positioned at the bottom of described mechanical valve 4, the described regulating valve stem 5 described mechanical valve 4 of traverse.
Described limit valve can be arranged at the middle part of described mechanical valve by those skilled in the art as required.
Construction of switch in this utility model is made up of together with limit valve mechanical switch, and generally one, can not be split; The knob of mechanical switch is converted to the rectilinear motion of valve rod by this structure by frame for movement.
Fig. 1 illustrate a kind of actually used in the structure of Combined transfer switch, Fig. 2 and Fig. 3 illustrates this structure structure when different on off state.
Fig. 2 and Fig. 3 contrasts it can be seen that regulating valve stem is when switching knob is in diverse location, and being exposed at the partial-length outside switching valve body can change, and then limit valve can be promoted to be in connection and disconnect state two kinds different.
In above-described embodiment, it is possible to will pass through to regulate the regulating valve stem of mechanical switch, it is achieved allow when rotary switch knob mechanical switch be become connection from disconnection, allow limit switch be gone off by connection.
In above-described embodiment, it is possible to the position of limit switch is installed to the centre position of mechanical switch, the equally possible effect reaching structure of the present utility model.
