The exhaust valve has the obvious advantages of replacing a safety valve and small workload of resistance fluid quantity detecting and replenishing resistance fluid.
Description
Technical field:
The utility model relates to a kind of exhaust technique, especially for the outlet valve of brushless self-control motor liquid resistance starter.
Background technique:
Brushless self-control motor liquid resistance starter, because its structure is relatively simple, cost is low and be widely used in the startup of heavy-duty motor.The patent No. is that 20092009258.8 utility model patent discloses a kind of outlet valve, has solved original liquid resistance starter outlet valve and can not overcome liquid resistance box and liquid resistance viewing window is set, adds the coefficient problem of resistor fluid mouth and safety valve and outlet valve.This model utility is through being widely used in recent years, because outlet valve is located in the cylindrical shell of liquid resistance box, the height of outlet valve housing is higher, in order to make it have the decompression function of safety valve, the pore diameter of outlet valve needs to strengthen, resistance liquid measure in the pore of this outlet valve is just large, the every startup of motor once will be discharged larger resistor fluid, cause resistor fluid in starting box to be less than when a certain amount of, just must supplement resistor fluid, the height and the filling resistor fluid that cause frequent detection resistor fluid liquid level, increased workload to user.
Summary of the invention:
The purpose of this utility model is to provide and a kind ofly can replaces safety valve and detect resistance liquid measure and the little a kind of outlet valve of supplementary resistor fluid workload.
The technological scheme that realizes the utility model object is, a kind of outlet valve, comprise valve casing and interior spool, spring and sealing gasket thereof, it is characterized in that: the lower end of described valve casing is provided with vertical outlet pipe and is connected with the horizontal outlet pipe of stock solution tube end plate bottom, the hole wall of described spool and described valve casing is slippery, on the side face of described spool, be distributed with longitudinally groove or on described spool, be distributed with hole longitudinally, it is relative with the annular end face of described valve casing lower end that the lower end surface of described spool is provided with sealing gasket.On the vertical outlet pipe of described outlet valve and stock solution tube end plate, overhanging horizontal outlet pipe is integral type outlet pipe, and the two ends of this integrated exhaust pipe are connected with described valve casing and stock solution tube end plate respectively, and is communicated with inner chamber and the stock solution tube inner chamber of valve casing respectively.On the vertical outlet pipe of described outlet valve lower end and stock solution tube end plate, overhanging horizontal outlet pipe is split-type structural.On described stock solution tube end plate, the external end head of overhanging horizontal outlet pipe is provided with vertical pipe, the side face of this pipe is provided with screw thread, the hole wall of the exhaust port of the termination of the vertical outlet pipe of described outlet valve lower end is provided with outside thread with the vertical outlet pipe of the described horizontal outlet pipe termination internal thread that matches, termination at the vertical outlet pipe of described horizontal outlet pipe termination is provided with cone, and the conical surface of this cone is relative with the aperture, small-diameter step hole of the vertical outlet valve tapped hole rear end of described outlet valve lower end.
The utility model has the little remarkable advantage of workload that replaces safety valve and detect resistance liquid measure and supplementary resistor fluid compared with the prior art.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the vent hole structure schematic diagram of the spool cylinder that shows of the A-A section of Fig. 1; Fig. 3 is the another kind of spool cylinder vent hole structure schematic diagram that the A-A section of Fig. 1 shows, Fig. 4 is the linkage structure schematic diagram of outlet valve and stock solution tube; Fig. 5 is the another kind of linkage structure schematic diagram of outlet valve and stock solution tube, and Fig. 6 is the sealed structural representation of spool cylinder and valve casing exhaust port, and Fig. 7 is the another kind of sealed structural representation of spool cylinder and valve casing exhaust port.
Embodiment:
In conjunction with above accompanying drawing, the utility model to be described in detail, in order overcoming when existing outlet valve starts, to discharge the defect that resistance liquid measure causes greatly increase detection resistance liquid measure and supplementary resistance liquid measure workload, adopt following technical proposals.Outlet valve 4 of the present utility model is located at outside stock solution tube 1 end plate, the vertical outlet pipe 3 of its lower end is connected with horizontal outlet pipe 2 overhanging on stock solution tube end plate, this linkage structure has following mode: the vertical outlet pipe 3 of the valve casing lower end of outlet valve is structure as a whole and with welding, is connected with stock solution tube with outlet valve respectively with horizontal outlet pipe 2, makes stock solution tube be communicated with (referring to Fig. 5) with outlet valve; Horizontal outlet pipe overhanging on the vertical outlet pipe of outlet valve and stock solution tube end plate is connected with welding, makes stock solution tube be communicated with (referring to Fig. 1) with outlet valve, and above-mentioned linkage structure is fixed connection structure, and its advantage is simple in structure, but non-dismountable.On the vertical outlet pipe of above-mentioned outlet valve and stock solution tube end plate, overhanging horizontal outlet pipe is connected to Split type structure, horizontal outlet pipe external end head on stock solution tube end plate is provided with the pipe 11 perpendicular with horizontal outlet pipe, this pipe is provided with the outside thread matching with internal thread pore with the vertical outlet pipe of outlet valve termination, this split-type structural need be established sealing mechanism, the termination of the horizontal outlet pipe on described stock solution tube end plate is cone, the aperture relative (referring to Fig. 4,6) of the conical surface of this cone and the taper hole of described vertical outlet valve outlet pipe tapped hole the inner.Spool 5 is the cylinder slippery with the hole wall of outlet valve valve casing, on the side face of this cylinder, be distributed with groove (referring to Fig. 2) longitudinally, or hole (referring to Fig. 3) longitudinally distributes on cylinder, between the upper-end surface of described spool and the cover plate 7 of outlet valve valve casing, be provided with spring 6, on this cover plate, have hole, on the lower end surface of spool, be provided with the sealing gasket 8 relative with valve casing lower end surface, the area of this sealing gasket is greater than the area in hole of the outlet pipe of valve casing lower end, this sealing gasket is connected (referring to Fig. 1) with screw with spool, above-mentioned sealing gasket can be that O RunddichtringO 10 is set in the stepped cylinder of described spool lower end, the major diameter cylinder of this stepped cylinder is relative (referring to Fig. 4 with the groove on described exhaust valve casing lower end surface, 5), also can make the seal ring that cross section is rectangle, this seal ring is set in stepped cylinder (referring to Fig. 6, 7).Described cover plate, is threaded as cover plate and valve casing port adopt for being flexibly connected with valve casing, or other Placements, is convenient to the resistor fluid in stock solution tube to detect.For the centrifugal switch in stock solution tube, do not change, this centrifugal switch also can be located at outside stock solution tube.The length of the outlet pipe of above-mentioned exhaust structure can be the shortest, thereby the aperture of outlet pipe can be strengthened by the requirement of safety valve, make the existing scavenging action of this outlet valve, has again the effect of safety valve, and the less advantage of amount of the resistor fluid of discharging while starting.
