Abstract
The utility model discloses a deflation valve of a cooling water pipe of an engine. The deflation valve comprises a valve seat and a valve deck covering the valve seat. The valve seat is installed on the cooling water pipe. The valve seat is provided with an exhaust vent which communicates the inside of the cooling water pipe with external air. The valve deck and the valve seat are in threaded connection. A choke plug used for sealing the exhaust vent is arranged inside the valve deck. Compared with the prior art, the deflation valve is installed on the cooling water pipe, and both the valve deck and the valve seat can be twisted off; when the cooling water pipe is arranged high and filled with cooling liquid in a static state, the valve deck is unscrewed, the exhaust vent enables the inside of the cooling water pipe to be communicated with the external air, therefore, the exhaust function can be achieved, gas accumulated in the cooling water pipe can be effectively exhausted, the static filling efficiency is improved, the effect that air resistance does not occur inside a cooling system when the engine operates is ensured, and the stability of filling and operation is ensured for the system finally.
Description
Technical field
The utility model relates to engine technology, and specifically, the utility model relates to a kind of bleed valve of cooling water pipe of engine.
Background technique
Water-cooling tube is one of component indispensable in the engine-cooling system circulation, play the effect of connecting engine body cooling system and car load radiator, warm braw, expansion tank, set up whole cooling system circulating cooling liquid circulation passage, get rid of unnecessary gas in cooling system.
At present, because design of Cooling System trends towards oversimplifying, reduce amount of parts in pipeline as far as possible, guarantee at utmost generalization of system layout.And some pipeline is because arranging reason, position is higher, when static state is annotated, because cooling liquid is to overflow up from the system bottom, and cause the part air to be stacked in the pipeline that layout is higher, go, can't effectively discharge, can cause cooling system filling discontented and in systemic circulation, form vapour lock, thereby affect the stability of system, even cause the inefficacy of system and the damage of some component.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of bleed valve of cooling water pipe of engine, is beneficial to the interior discharge that is gathered in the gas in water-cooling tube of water-cooling tube that position is higher.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of bleed valve of cooling water pipe of engine, comprise valve seat and cover the valve gap on valve seat, valve seat is arranged on water-cooling tube, valve seat is provided with the exhaust port that is communicated with the inside and outside atmosphere of water-cooling tube, valve gap for being threaded, is provided with plug for seal vents in valve gap inside with valve seat.
At the cavity that is provided with the plug that allows on described valve gap on described valve seat and inserts, described exhaust port is located on the sidewall of this cavity, in the bottom of cavity, is provided with the vent with described water-cooling tube internal communication.
Between the cavity of described plug and described valve seat, be provided with sealing configuration.
Described sealing configuration comprises the projection of the bottom that is located at described cavity and is enclosed within the seal ring on this projection, on described plug, is provided with the groove that can allow projection insert, and described vent passes projection.
On described valve gap, be provided with a plurality of anticreep pawls that can be stuck on described valve seat.
Described valve gap is cylindrical, and described anticreep pawl edge on valve gap circumferentially is evenly equipped with four.
The utility model adopts technique scheme, compared with prior art, this bleed valve is arranged on water-cooling tube, between valve gap and valve seat, can turn on, when line arrangement higher, when static state adds inject cooling liquid, valve gap is unscrewed, exhaust port is communicated with water-cooling tube inside with outside atmosphere, can play the effect of exhaust, make the gas of piling up in pipeline effectively be discharged, improve static filling rate, while having guaranteed the motor operation, in cooling system, can not produce vapour lock, the filling of finally assurance system and the stability of moving.

Embodiment
Be the bleed valve of a kind of cooling water pipe of engine 1 of the present utility model as shown in Figure 1, Figure 2, Figure 3 and Figure 4, it comprises valve seat 2 and covers the valve gap 4 on valve seat 2, valve seat 2 is arranged on water-cooling tube 1, valve seat 2 is provided with the exhaust port 5 that is communicated with water-cooling tube 1 inside and outside atmosphere, by the outside exhaust of exhaust port 5.Valve gap 4 for being threaded, makes valve gap 4 can turn on exhaust and tighten sealing with valve seat 2, in valve gap 4 inside, is provided with the plug for seal vents 5.
As shown in Figure 1, at the cavity that is provided with the plug that allows on valve gap 4 on valve seat 2 and inserts, exhaust port 5 is located on the sidewall of this cavity, in the bottom of cavity, is provided with the vent 7 with water-cooling tube 1 internal communication.After turning on valve gap 4, water-cooling tube 1 is communicated with outside atmosphere by the exhaust port 5 on vent 7, cavity.
As depicted in figs. 1 and 2, between the cavity of plug and valve seat 2, be provided with sealing configuration, the sealing structure comprises the projection of the bottom that is located at cavity and is enclosed within the O RunddichtringO 3 on this projection, on plug, be provided with the groove that can allow projection insert, vent 7 passes projection, when closing bleed valve, tighten valve gap 4, the recess cover of plug bottom is on projection, and the plug bottom also is pressed on seal ring, guarantees vent 7 sealings.
As depicted in figs. 1 and 2, valve gap 4 is cylindrical, on valve gap 4, is being provided with four anticreep pawls 6 that can be stuck on valve seat 2, anticreep pawl 6 edge on valve gap 4 circumferentially is uniformly distributed, anticreep pawl 6 is stuck in the outer surface of valve seat 2, makes valve gap 4 can not back out fully, and causes the loss of valve gap 4.The annular knurl design of valve gap 4 outer surfaces, can guarantee in the situation that, not by instrument, by hand valve gap 4 tightened or become flexible.
As shown in Figure 3, when needs static state adds inject cooling liquid, valve gap 4 is unscrewed, plug moves up, and exhaust port 5 exposes, and the gas in water-cooling tube 1 discharges through vent 7, exhaust port 5 successively, after gas is all emptying, adds inject cooling liquid.As shown in Figure 4, after filling completes, turn valve gap 4 downwards, until valve gap 4 is tightened, in bleed valve inside, the close exhaust port 5 of blocking of plug, and between bottom and valve seat 2 cavitys due to the sealing of O RunddichtringO 3, can guarantee again under 3bar hydraulic pressure, without revealing.
