Abstract
The utility model discloses a diaphragm type disconnecting valve. The disconnecting valve is composed of a valve cover, a valve core, a valve rod, a valve rod driving mechanism and a rubber diaphragm, wherein, the edge of the rubber diaphragm is hermetically matched with the valve cover. The utility model is characterized in that the valve cover is formed with a guide cavity in a concave manner from one side of the valve rod, the valve core can be movably arranged in the guide cavity, one end of the valve rod is connected with the valve rod driving mechanism, the other end is fixed with a magnetic piece 1 made of permanent-magnet materials, the valve core is fixed with a magnetic piece 2, the magnetic piece 1 is adjacent to the outer side wall of the guide cavity, the magnetic piece 1 is coupled with the magnetic piece 2 through the mutually attracting magnetic forces, and the valve core is matched with the rubber diaphragm in a downward pressing way. The utility model arranges the magnetic piece 1 on the valve rod and the magnetic piece 2 on the valve core, the valve rod drives the valve core to move up and down through the magnetic force, a through hole is not required to be arranged on the valve cover, and the valve cover is a complete component without a hole or a gap, thus, the space between the upper part and the lower part of the valve cover is completely sealed.
Description
Technical field
The utility model relates to a kind of stop valve, particularly a kind of membrane type stop valve that is applicable to the household tap water metering.
Background technique
Application number is that 200620040556.9 utility model patent specification discloses a kind of membrane type stop valve, this membrane type stop valve includes valve gap, spool, valve rod, the elastomer diaphragm that driving mechanism between the micromachine of actuate valve stem, micromachine and valve rod and edge cooperate with valve bonnet seal.Valve gap is provided with a through hole, and valve rod passes through hole fixedlys connected with spool, spool under the drive of valve rod with elastomer diaphragm under press fit.
The valve gap of the membrane type stop valve of said structure is provided with through hole and is used for valve rod and passes with spool and be connected, though valve rod and through hole joint are provided with seal ring, but obviously can not realize sealing fully between valve rod and the through hole, therefore the water of bonnet lower branch more or less can enter into valve gap top motor and driving mechanism position by the slit, thereby corrosion electrical motor and driving mechanism, even cause the motor short circuit to damage.
The model utility content
The purpose of this utility model is to overcome above technological deficiency, and a kind of membrane type stop valve is provided, the sealing fully between two-part up and down of its valve gap.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of membrane type stop valve, comprise valve gap, spool, valve rod, the valve rod driving mechanism, and the elastomer diaphragm that cooperates with valve bonnet seal of edge, it is characterized in that: described valve gap is to recessed formation one directed cavity of valve rod one side, and spool is located in the directed cavity movably, one end of valve rod is connected with the valve rod driving mechanism, the fixing magnetic part I that makes by permanent-magnet material of the other end, spool is fixed with magnetic part II, magnetic part I and directed cavity outer side wall close neighbour, magnetic part I and the coupling of magnetic part II opposite sex magnetic force, press fit under spool and the elastomer diaphragm.
The beneficial effects of the utility model are: the utility model is provided with magnetic part I on valve rod, magnetic part II is set on spool, valve rod drives spool by magnetic force and moves up and down, through hole need be set on valve gap, valve gap is the also seamless complete member of an atresia, so valve gap sealing fully between two-part up and down.
Further describe below in conjunction with accompanying drawing and embodiment
Description of drawings
Fig. 1 is existing membrane type stop valve structure schematic representation;
Fig. 2 is the utility model specific embodiment structural representation;
Embodiment
As shown in Figure 2, a kind of membrane type stop valve comprises valve gap 5, spool 6, valve rod 3, the micromachine 1 of actuate valve stem 3, the elastomer diaphragm 9 that driving mechanism between micromachine 1 and the valve rod 3 and edge and valve gap 5 are sealed and matched.The upper end of valve rod 3 is provided with screw thread, and the part that valve rod 3 is provided with screw thread is enclosed within the traction valve rod inserts 2, and micromachine 1 is fixed on the valve gap 5, and micromachine 1 rotates by gear set drive valve rod 3 and then axially activity of actuate valve stem 3.Valve gap 5 of the present utility model is the also seamless complete members of an atresia, and valve gap 5 is to the recessed formation one columniform directed cavity of valve rod 3 one sides, and the lower end of valve rod 3 is provided with a columnar pallet 4, and the opening of pallet 4 is towards directed cavity.The inboard bead of pallet 4 is fixed with a permanent magnetic ring 8 of being made by NdFeB material, and the internal diameter of magnet ring 8 and the external diameter of directed cavity are suitable.Magnet ring 8 is enclosed within on the directed cavity.Spool 6 is located in the directed cavity movably, and the diameter of spool 6 and the internal diameter of directed cavity are suitable, and the upper end of spool 6 is provided with columniform cavity volume, is provided with the magnet steel 7 that permanent-magnet material is made in the cavity volume, and magnet steel 7 upper ends are provided with Sealing and fixedly connected with spool 6.
When the utility model is closed, valve rod 3 moves down under the drive of micromachine 1, the magnet steel 7 different in nature magnetic force couplings on magnet ring 8 on the valve rod 3 and the spool 6, under the drive of magnetic force, moving down of spool 6 along directed cavity, and then press down elastomer diaphragm 9 closed valve seats and realize closing.During unlatching, spool 6 moves up under magnetic force, the following press fit of spool 6 contact and elastomer diaphragm 9, elastomer diaphragm 9 jack-up upwards under hydraulic action, valve opening.
The utility model drives spool 6 by magnetic force and moves, need perforate on valve gap 5, so valve gap can be realized between two-part about in the of 5 sealing fully.
