Abstract
The utility model discloses a water discharging valve, which has the design of a large and a small double water discharging ports and a favorable sealing effect. The water discharging valve which can prevent water leakage comprises a circular pipe-shaped valve body with external threads, a screw nut of a water outlet, and a rubber pad with a center hole, wherein the screw nut of the water outlet is arranged on one end of the circular tube-shaped valve body. The utility model is characterized in that an internal baffle plate is connected with the valve body pipe as a whole, and the rubber pad with a center hole is arranged on the circular pipe-shaped valve body abutted with the internal baffle plate; the other end surface of the circular pipe-shaped valve body, which is abutted with the rubber pad, is provided with an external baffle plate; a screwed nut which is screwed tightly with the external baffle plate 5 is arranged on the circular pipe-shaped valve body. A screwed shim is arranged between the external baffle plate and the screwed nut. The screwed nut is a butterfly nut. The water discharging valve is provided with double water discharging ports. The installation or the disassembly of the utility model, which is convenient and does not need any tool, can be realized only by manual work.
Description
Technical field
The utility model relates to a kind of drain valve.
Background technique
A kind of drain valve that uses in the prior art, the rubber pad of its inner nut as baffle plate, band center hole, as the outer nut of exterior siding adopts traveling nut to clamp rubber pad, its shortcoming be cause tight with seal for pipe joints, installation or removal are inconvenient.
Original technical finesse mode is: be provided with internal thread in the weep hole, the water blockoff screw rod that is with rubber washer screwed up with a wrench in weep hole from outside to inside, thereby reach water plugging effect, unclamp during draining and get final product.Said method is not owing to there is a double water function, and a small amount of draining can't be carried out, from outside the shutoff method that compresses toward in, effectively water blockoff is prone to the infiltration phenomenon, the means of fixation that screws up with a wrench also is inconvenient to mount and dismount.
The utility model content
The purpose of this utility model provides a kind of drain valve, and it not only has big or small double mouth of a river design and excellent sealing effect, can prevent infiltration, and installation or removal is very convenient, need not any instrument, only can realize by hand.
The utility model is achieved in that a kind of drain valve comprises the rubber pad with externally threaded tubular shape valve body, water outlet nut, band mesopore, the water outlet nut is installed in an end of tubular shape valve body, its special way is: lining baffle plate and valve body tube are connected as a single entity, the rubber pad of band center hole is installed on the tubular shape valve body near the lining baffle plate, other end near rubber pad, there is an exterior siding to be installed on the tubular shape valve body, on the tubular shape valve body, also have one to screw nut and cooperate, exterior siding and screw and tighten pad between the nut with exterior siding.
According to the utility model, its special way is: rubber pad can produce the crooked metamorphosis that expands with inside and outside baffle plate extruding.
According to the utility model, its special way is: the described nut that screws is a wing nut, possesses the labour-saving leverage.
According to the utility model, described drain valve has the double mouth of a river.
The utility model drain valve, in baffle plate and valve body tube be connected as a single entity, the rubber pad of band center hole is between lining baffle plate and exterior siding, turn clockwise and screw nut, just baffle plate and exterior siding clamp rubber pad in can making, the extruding rubber pad produces crooked dilatancy, hold out against casing weep hole inwall, realize drain valve and seal for pipe joints, be rotated counterclockwise and screw nut, just can from weep hole, take out, reach the effect of draining, the water outlet nut that the pipe valve head can be directly outwarded winding in a small amount of draining can carry out, two sections drainings, adapt to the different situations needs, also possess excellent sealing effect, and installation or removal are very convenient, need not any instrument, only can realize by hand.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of drain valve comprises is with externally threaded tubular shape valve body 2, water outlet nut 1, the rubber pad 6 of band center hole, water outlet nut 1 is installed in an end of tubular type valve body 2, tubular shape valve body 2 is connected as a single entity with lining baffle plate 7, the rubber pad 6 of band center hole is installed on the tubular type valve body 2 near lining baffle plate 7, on the other end near rubber pad 6, there is an exterior siding 5 to be installed on the tubular shape valve body 2, on tubular shape valve body 2, also have one to screw nut 3 and cooperate with exterior siding 5, turn clockwise and screw nut 3, then make exterior siding 5 extruding rubber pads 6, rubber pad produces crooked dilatancy, holds out against casing weep hole inwall, realize the sealing of drain valve and weep hole, screw nut 3 otherwise be rotated counterclockwise, rubber pad 6 recovers nature, drain valve can be taken out from weep hole.The described nut 3 that screws can adopt wing nut.
Described drain valve has the double mouth of a river.
As further improvement of the utility model, exterior siding 5 and screw and tighten pad 4 between the nut 3.
The described nut 3 that screws adopts wing nut, possesses laborsaving one leverage.Thereby need not any instrument, only can realize installation or removal by hand.
Claims (4)
