The seal ring is fixed with the seat body; the topside valve house is sleeved with the cylinder body whose lower end presses against the seal ring; passing through the topside valve house cover, the lifting device is fixedly connected with topside valve house cover; two ends of the retracting spring are respectively connected with the lifting device and the fixing frame; the fixing frame is fixed on the lower side of the cylinder body of the valve seat. The drain valve has the advantages of simple structure, good sealing performance and flexible and convenient operation.

Description

Draining valve

The utility model discloses a kind of valve, the draining valve that especially a kind of toilet tank is used.

Draining valve is vital parts in the water tank, and the sealing of water tank depends primarily on the sealing performance of draining valve.Drain valve structure in the water tank is to be made of valve seat and valve gap mostly at present, and places the valve seat mesopore to reach sealing effectiveness valve gap.The more of usefulness is ball valve or plug valve in the market, its sealing effectiveness is undesirable, because of valve gap heaviness inconvenient operation, example Chinese patent 96246071.0 discloses a kind of radiator valve, it is made up of valve gap, valve seat and anti-overflow pipe, it passes through at the housing edge of valve gap mounting circular ring shape iron plate and annular seal sheet, and at the edge of valve seat magnet steel is installed and reaches sealing effectiveness, its complex structure, inconvenient operation, sealing effectiveness is undesirable, and iron plate, magnet steel are immersed in the water for a long time and easily get rusty, shorten application life, needs often maintenance; If want the enhanced leaktightness effect, must make it produce bigger pressure and reach sealing effectiveness by increasing the valve gap own wt, therefore, drain operation is very inconvenient.

The purpose of this utility model is that to overcome prior art not enough and a kind of simple in structure, better tightness, draining valve flexible to operation be provided.

The technical scheme that realizes the utility model purpose is: a kind of draining valve, include valve gap and valve seat, wherein, valve gap is formed by fixedly connecting by valve bonnet and valve bonnet lid, valve seat is fused by cylindrical shell and the pedestal that downside is provided with at least one hole, also includes sealing ring, lifting appliance, return spring and fixed mount; Described sealing ring and pedestal are fixed, and valve bonnet is placed on the cylindrical shell, and its lower end is mortgaged mutually with sealing ring, and lifting appliance passes the valve bonnet lid and fixedlys connected with the valve bonnet lid, and the return spring two ends are connected with fixed mount with lifting appliance respectively, and fixed mount is fixed on valve seat cylindrical shell downside.

Adopt the positive effect that the utlity model has of technique scheme: because valve bonnet is placed on the valve seat cylindrical shell, the valve bonnet lower end is mortgaged mutually with sealing ring, thereby makes the water in the draining valve outside can't leak into gutter; Water must enter by the Kong Caineng on the valve seat cylindrical shell if will enter gutter, and valve bonnet produces certain pressure by return spring and acts on sealing ring on the valve seat pedestal, and valve outside water can't enter cartridge bore, so sealing effectiveness is better.During draining, upwards draw lifting appliance, valve gap moves on together in company with lifting appliance, and water enters gutter by the valve seat cartridge bore, and this moment, external force was equal to the elastic force of return spring, and external force disappears, and return spring resets, valve bonnet again with valve base sealing, it is flexible to operation.The utility model is simple in structure, makes easily, and long service life is difficult for breaking down.

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Fig. 1 is the structural representation of return spring of the present utility model when resetting;

Fig. 2 is the structural representation when drawing on the valve bonnet of the present utility model.

The utility model illustrated in figures 1 and 2 includes valve gap and valve seat 1, valve gap is made of valve bonnet 2 and valve bonnet lid 3, valve bonnet 2 can be made of one with valve bonnet lid 3, also can adopt and be threaded or the screw connection, valve seat 1 is fused by the cylindrical shell 1-1 pedestal 1-2 that downside is provided with at least one hole 1-1-1, it also includes sealing ring 4, lifting appliance, return spring 5 and fixed mount 6; Described sealing ring 4 is fixed by screw 9 and pedestal, valve bonnet 2 is placed on the cylindrical shell 1-1, among this embodiment, valve bonnet 2 upper ends are threaded with valve bonnet lid 3, the lower end is mortgaged mutually with sealing ring 4, lifting appliance passes valve bonnet lid 3 and covers 3 with valve bonnet fixedlys connected, and return spring 5 two ends are connected with fixed mount 6 with lifting appliance respectively, and fixed mount 6 is fixed on valve seat cylindrical shell 1-1 downside.Lifting appliance in the present embodiment is used to spur valve bonnet lid 3 and valve bonnet 2 moves simultaneously, and make on the return spring 5 and draw, it is by hanging tight screw 7 and constitute with its fixing lifting arm 8, is provided with the hole hanging tight screw 7 lower ends, and return spring 5 upper ends are passed the hole and hung tight screw 7 and be connected.After external force disappeared, return spring 5 resetted, and drove valve bonnet 2 and pressed down, and valve bonnet 2 mortgages on the sealing ring 4, and sealing ring 4 can adopt rubber ring.When the utility model is specifically implemented, the valve seat bottom is connected with outlet pipe 12, can pass the joint 10 of ABS material with hanging tight screw 7, joint 10 lower ends and valve bonnet lid 3 are fixing, last termination telescoping tube 11, this valve is inner isolates with water-stop thereby can make, and valve inner and outside air and blow-by, so when upwards drawing lifting arm 8, need not too big active force can mention valve gap, so the utility model is easy to use, flexible, good airproof performance, when being used, can reach water-saving result preferably with water tank.
