Abstract
A kind of gas ratio valve, comprise valve body, valve seat, valve port, valve body is provided with inner chamber circular hole, skeleton is provided with in valve port, valve port upper end and body cavity circular hole interference fit, also comprise and being fixed on valve body and the baffle plate contacted with valve port lower end, the part that skeleton stretches out valve port to be positioned on baffle plate and with valve body close contact, can ensure that the cutoff function of gas ratio valve normally uses, the reliability of gas ratio valve can be ensured again.
Description
Technical field
The utility model relates to a kind of gas ratio valve.
Background technique
Gas ratio valve is widely used in being with on the gas water-heater of automatic constant-temperature function, and general employing moving-magnetic type structure.On market, moving-magnetic type gas ratio valve comprises a stop valve and a ratio adjusting valve usually, and wherein ratio adjusting valve not only proportional regulatory function, also has cutoff function.
Be in particular in: valve seat and magnet jump ring link into an integrated entity, ratio coil, under driving current effect, can make magnet and valve seat move along valve port axial direction, realizes proportion adjustment function by controlling gap length between valve port and valve seat; When driving current is less or ratio coil blackout when, valve seat is pressed on valve port under the effect of magnetic pull, realizes cutoff function.
Existing moving-magnetic type gas ratio valve, the shape of valve port is circular, and valve seat fitting surface is sphere, and for ensureing that valve port and valve seat can closely cooperate, valve port adopts the rubber material of embedded skeleton to make.During assembling, the mode of riveted joint is pressed on the skeleton of valve port on valve body, thus secures valve port.But during riveted joint, skeleton is not only subject to the beneficial effect of axial pressing force, is subject to the illeffects of lateral extrusion power simultaneously.Extruding force makes valve port roundness deformation, thus has gap when causing valve port to coordinate with valve seat, and cutoff function is lost.To reduce the illeffects of extruding force, will inevitably reduce the beneficial effect of impacting force simultaneously, valve port is easily got loose, reliability reduces.
Summary of the invention
Technical problem to be solved in the utility model to provide a kind of gas ratio valve, can ensure that the cutoff function of gas ratio valve normally uses, can ensure again the reliability of gas ratio valve.
The technological scheme that the utility model solves the employing of its technical problem is: comprise valve body, valve seat, valve port, valve body is provided with inner chamber circular hole, skeleton is provided with in valve port, valve port upper end and body cavity circular hole interference fit, also comprise and being fixed on valve body and the baffle plate contacted with valve port lower end, the part that skeleton stretches out valve port to be positioned on baffle plate and with valve body close contact.
Also comprise screw, baffle plate is provided with screw hole, and bolts through bolt holes is fixed on valve body, and skeleton is positioned at the sidewall of baffle plate upper part and the cylinder close contact of screw.
Described baffle plate riveted joint is fixed on valve body.
Described baffle plate by glue on valve body.
Described baffle plate is made up of galvanized sheet or stainless steel.
Described skeleton is made up of steel or copper or aluminium.
The utility model compares produced beneficial effect with background technique: be fixed on valve body and the baffle plate contacted with valve port lower end because the utility model adopts also to comprise on prior art basis, the part that skeleton stretches out valve port to be positioned on baffle plate and with the scheme of valve body close contact, skeleton does not need to be riveted on valve body, without the need to bearing the illeffects of lateral extrusion power, only need the beneficial effect bearing axial pressing force, can ensure while can not causing valve port roundness deformation that valve port is fixed, not easily get loose, can ensure that the cutoff function of gas ratio valve normally uses, the reliability of gas ratio valve can be ensured again.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the exploded view of valve body 1 in Fig. 1, valve seat 2, valve port 4 attachment portion.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the present embodiment comprises valve body 1, valve seat 2, valve port 4, valve body 1 is provided with inner chamber circular hole 3, skeleton 6 is provided with in valve port 4, valve port 4 and body cavity circular hole 3 interference fit, also comprise and being fixed on valve body 1 and the baffle plate 5 contacted with valve port 4 lower end, the part that skeleton 6 stretches out valve port 4 to be positioned on baffle plate 5 and with valve body 1 close contact.Described baffle plate 5 is one block of plate.
The face that valve seat 2 matches with valve port 4 is sphere, on valve port 4, corresponding with above-mentioned sphere is circular, skeleton 6 is embedded on valve port 4, existing skeleton all becomes bending-like, one end of bending is positioned at valve port 4 inside, the other end have part stretch out valve port 4 and with valve body 1 close contact, under the driving current effect of Proportional valve drive coil, valve seat 2 moves up and down with upper magnet, gap between valve port 4 and valve seat 2 fitting surface changes, in the utility model, the other end of skeleton does not need to be riveted on valve body 1, without the need to bearing the illeffects of lateral extrusion power, valve port 4 roundness deformation can not be caused, when driving current is less or ratio coil blackout when, valve seat 2 is pressed on valve port 4 under the effect of magnetic pull, gapless between valve port 4 and valve seat 2 fitting surface, realize cutoff function, skeleton 6 need bear the beneficial effect of axial pressing force simultaneously, prevents valve port 4 from getting loose along shaft core direction, fixed, effectively ensures the reliability of gas ratio valve.
Further, also comprise screw 7, baffle plate 5 is provided with screw hole, and screw 7 is fixed on valve body 1 through screw hole, and skeleton 6 is positioned at the sidewall of baffle plate 5 upper part and the cylinder close contact of screw 7.This structure can make baffle plate 5 more be securely fixed on valve body 1, and assembly technology is simple, simple operation.
In addition, described baffle plate 5 can also rivet be fixed on valve body 1 or by glue on valve body 1, as long as can by fixed for baffle plate 5.
Referring to Fig. 1 and Fig. 2, due to little with valve port 4 area of contact on the left of valve body 1 in the present embodiment, therefore baffle plate 5 directly can be riveted or be welded on valve body 1, large with valve port 4 area of contact on the right side of valve body 1, for fixing more reliable, available screw 7 fixed dam 5.In addition, as shown in Figure 2, the plate washer 5 of the left and right sides can be made up of one block of plate, if rigging position is limited, the baffle plate 5 of the left and right sides also can be made up of two boards respectively.
Described baffle plate 5 can be made up of galvanized sheet or stainless steel, firm in structure.
Described skeleton 6 is made up of steel or copper or aluminium, draws materials conveniently.
