Abstract
The utility model relates to a valve with a valve cavity structure, which can especially avoid that the valve or a pipeline is frozen or damaged by liquid left in a pipeline system and at the inner part of the valve or the valve is blocked in precipitability after the valve is closed; a discharging clearly hole is arranged on a valve body near the bottom part of the valve cavity. A guide tube which can guide liquid in the valve cavity is arranged at the position of the discharging clearly hole. When the valve is closed, the guide tube is opened; making use the principle of siphonage thoroughly and clearly discharges left liquid in the pipeline and the valve cavity for frost damage prevention and precipitability blocking prevention; the utility model can avoid left corrosive liquid damage to the pipeline and the valve.
Description
The utility model relates to a kind of shutoff valve.
At present general shutoff valve still has residual liquid to accumulate in pipeline and valve internal after closing.This part hydrops can cause following harm at pipeline and valve internal:
1, after hydrops congeals, perhaps after the precipitability species precipitate in the hydrops, can cause valve to open difficulty and pipeline blockage again.
2, the volumetric expansion meeting after the hydrops degree of depth is congealed causes the bursting by freezing of freezing to death of valve and pipeline.
3, the corrosivity of hydrops or dangerous valve and the pipeline of can causing are accumulated continuity on time of standing to corrode or the dangerous time that exists.
The purpose of this utility model can reach the purpose of anti-freezing anti-blocking to the thorough valve of getting rid of of the hydrops of output pipe and valve inside cavity after providing a kind of closing.
The purpose of this utility model is achieved in that on the valve body of at present general shutoff valve, near the position perforate of valve pocket as putting clear opening, in putting the clear opening place conduit of drawing liquid in the valve pocket is set.Should set up the keying that small-sized ball valve is controlled conduit on the conduit.During use shutoff valve is installed in the lowest part of pipeline.Like this, when valve closing, open conduit, because siphon principle, the hydrops that remains in pipeline and valve internal can thoroughly be discharged to pipeline and valve outside by putting clear opening.
Since emptying hydrops, just prevented that the freeze injury that causes because of hydrops and precipitability from stopping up, and the harm that can avoid the corrosivity raffinate that pipeline and valve are caused.After closure catheter for closing, the existence of putting clear opening and conduit does not have any harmful effect to the work of valve.The embodiment who does by the accompanying drawing structure has showed above-mentioned beneficial effect.
Accompanying drawing is a structural representation of the present utility model.In the drawings: 1, valve pocket 2, valve body 3, put clear opening 4, conduit
Realize that best way of the present utility model is that valve body (2) at stop valve is gone up in offering near the position of valve pocket (1) bottom and put clear opening (3), and go up to be provided with or can be provided with to be communicated with at valve body (2) and put the conduit (4) of clear opening (3).Conduit (4) tilts to oblique below.
Claims (3)
1, anti-freezing anti-blocking valve in offering and put clear opening near the valve pocket bottom position, in putting the conduit that the clear opening position was provided with or can be provided for drawing liquid in the valve pocket, is characterized in that having on valve body and puts clear opening on valve body, is provided with or conduit can be set.
2, anti-blocking valve according to claim 1 is characterized in that: put the position that clear opening is in close valve pocket bottom.
3, anti-blocking valve according to claim 1 is characterized in that: the position setting of putting clear opening in connection maybe can be provided with conduit.
