Abstract
The utility model discloses an automatic water discharge valve which is used for the frost prevention of a radiator, comprising a tubular casing (3), a valve seat (1), a valve cover (4), a tapered valve core (11), a shipper rod (8), a spring (2), a bellows (7) and a fixed tray (6), wherein, the both ends of the tubular casing (3) are respectively connected with the valve seat (1) and the valve cover (4), the tapered valve core (11) is arranged in the internal tapered hole of the valve seat (1), the tapered valve core (11) is fixed with the shipper rod (8), the shipper rod (8) is sheathed with the spring (2), one end of the bellows (7) is arranged on the shipper rod (8), the other end of the bellows (7) is arranged on the fixed tray (6) which is fixed in the valve cover (4), and the fixed tray (6) is provided with a plurality of drainage holes. The automatic water discharge valve utilizes the theory of the heat expansion and cold contraction of the bellows to control the discharge of the cool water of the radiator, which effectively prevents the frost crack of the radiator and an engine in winter. The utility model has the advantages of simple structure, convenient use and installation.
Description
The utility model relates to a kind of discharging valve, the automatic drain valve that the water tank of a kind of suitable motor car engine of more specifically saying so was used in severe winter.
At present, motor car engine is after working one day severe winter, and the driver must bleed off the water tank in the engine water tank, in order to avoid motor or water tank are damaged by frost.If forgotten to discharge water, through the severe cold at a night, might be water tank and motor bursting by freezing; If outdoor cold weather, by day dead time long slightly, also can cause the bursting by freezing of water tank and motor.
The purpose of this utility model is when having designed a kind of cooling water in water tank in order to overcome above-mentioned the deficiencies in the prior art part and dropping to 0～4 ℃, the automatic drain valve that the water in the water tank is discharged.
The purpose of this utility model can realize in the following manner: a kind of antifreeze automatic drain valve of radiator that is used for, include the housing of a tubulose, its two ends are connected with valve seat and valve gap respectively, described valve seat upper end is threaded with the radiator dewatering orifice and links to each other, be mounted with the spool of taper in the valve seat internal tapered hole, be fixed with movement rod on the spool, be set with spring on the movement rod, one end of bellows is placed on the movement rod, the other end is placed on the fixed tray that is fixed in valve gap, has the plurality of rows water hole on the fixed tray.
The utility model compared with prior art has following advantage: the utility model utilizes the principle of expanding with heat and contracting with cold of bellows, thereby handles movement rod by bellows, makes spool and valve base chamber that relative displacement be arranged, and realizes discharging water automatically.When the cooling water in the water tank drops to 0～4 ℃, spool and valve seat from.Water in the water tank just is discharged, thereby avoids water tank and motor by bursting by freezing.This valve arrangement is simple, and is easy to install, is applicable on all motors to use.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
With reference to the accompanying drawings: a kind of antifreeze automatic drain valve of radiator that is used for, include the housing (3) of a tubulose, its two ends in succession respectively valve seat (1) and valve gap (4), there is outside thread the upper end of valve seat (1), this valve can be linked to each other with the weep hole on the water tank, valve seat has cone shape hole in (1), tapered spool (11) is placed on the cone shape hole of valve seat (1), be fixed with movement rod (8) on the spool (11), be set with spring (2) on the movement rod (8), one end of bellows (7) links to each other with movement rod (8), the other end links to each other with discoid fixed tray (6), fixed tray has some weep holes on (6), and fixed tray (6) is fixed in the valve gap (4), is fixed with outlet pipe (5) on the hole of the lower end of valve gap (4).Be fixed with frame-like pull bar (9) on spool (11) lower end surface, the weep hole on the fixed tray (6) is passed in its lower end, and pull bar (9) lower end is fixed with a bar, is used for handling spool (11).One location screw (10) is arranged on the sidewall of valve seat (1), valve seat (1) and housing (3) are not thrown off because of vibration.On the circular hole of the lower end of valve gap (4), be fixed with outlet pipe (5).
Working principle: when the cooling water in the water tank dropped to 0～4 ℃, bellows (7) shrank, and drove movement rod (8) and moved down, and is subjected to displacement thereby make between spool (11) and the valve seat (1), thereby the cooling water in the water tank is discharged; When the cooling water temperature in the water tank rises, bellows (7) expands, drive on the movement rod (8) and move, make between spool (11) and valve seat (1) and closely cooperate, cooling water in the water tank is not discharged, and when water temperature continued to raise, bellows (7) continued to expand, spring (2) just is compressed, thereby guarantees the working life of bellows (7).
Claims (4)
1, a kind of automatic drain valve, it is characterized in that: housing (3) with a tubulose, its two ends are connected with valve seat (1) and valve gap (4) respectively, the upper end of valve seat (1) is threaded with the radiator dewatering orifice and links to each other, be mounted with the spool (11) of taper in valve seat (1) internal tapered hole, be fixed with movement rod (8) on the spool (11), put spring (2) on the movement rod (8), one end of bellows (7) is placed on the movement rod (8), the other end is placed on the fixed tray (6) that is fixed in the valve gap (4), and fixed tray has the plurality of rows water hole on (6).
2, according to the described automatic drain valve of claim 1, it is characterized in that: be fixed with pull bar (9) on the described spool (11), described pull bar (9) is frame-like, and the weep hole on the fixed tray (6) is passed in its lower end, and pull bar (9) lower end is fixed with bar.
3, automatic drain valve according to claim 1 is characterized in that: be fixed with outlet pipe (5) on the hole of described valve gap (4) downside.
4, according to claim 1,2 or 3 described automatic drain valves, it is characterized in that: on the sidewall of valve seat (1), be mounted with positioning screwn (10).
