Abstract
The utility model discloses a blowdown valve, which includes a straight-through pipe body, a valve body, a blowdown port and a bolt plug, wherein one end of the valve body is integrally connected with the pipe body, and a threaded hole is formed in the end wall at the other end of the valve body; the valve body includes the valve seat and the valve core; and the bolt plug is matched with the threaded hole. The blowdown valve is characterized in that the blowdown port is positioned on the side surface of the valve body; the valve seat is positioned on the inner side of the pipe body and fixed on the inner wall at one end of the valve body; an end wall at the other end of the valve body and the valve core are connected through a spring; and the valve core can move up and down along with the spring. The blowdown valve can realize automatic blowdown and prevent blockage.
Description
Technical field
The utility model relates to a kind of blowdown valve, particularly, can carry out blowdown and anti-blocking blowdown valve automatically.
Background technique
In the pipeline road, especially perhaps exist in the pipeline of lime-ash at the fluid pipeline that has impurity that has the blowdown needs, need to install the ordering valve usually, so that dirt is discharged smoothly, thereby the downstream water is met the demands.In existing blowdown valve; Blind pipe is installed usually, and this has caused under the situation of Open valve not, and dirt still can flow into blind pipe; Because the accumulation of dirt in blind pipe; When needing Open valve discharging dirt, dirt also is difficult to discharge from discharge pipe in the future, only if frequent Open valve is so that prevent debris accumulation.In addition, when needs discharging dirt, require manual work to switch closing of blowdown valve, this is the work of making us bothering, the labor intensive cost.
The model utility content
To prior art problems, the utility model provides a kind of blowdown valve, and it can carry out blowdown automatically and have choke preventing function.
The blowdown valve of the utility model comprises: straight-through body; Valve body, an end of this valve body is connected in said body integratedly, and has tapped hole on the end wall of the other end, and said valve body comprises valve seat and spool; Sewage draining exit; Embolism with said tapped hole cooperates is characterized in that, said sewage draining exit is positioned at the side of valve; Said valve seat is positioned at the body inboard and is fixed in the inwall of said valve body one end; Link together via spring between the end wall of the other end of said valve body and the said spool, said spool can move up and down with spring.
In above-mentioned blowdown valve, said valve seat is a ring.
According to the blowdown valve of the utility model, can realize the effect of anti-blocking and automatic pollution discharge.
Description of drawings
Fig. 1 is the External view according to the blowdown valve of the utility model.
Fig. 2 is the sectional view of the amplification of said blowdown valve, (a) state when showing valve closing wherein, the state when (b) showing valve opening.
Embodiment
Below, will describe embodiment in detail with reference to attaching Fig. 1 and 2 according to the blowdown valve of the utility model.
As illustrated in fig. 1 and 2, comprise according to the blowdown valve 10 of this enforcement: straight-through body 1; The valve body 2 of ring, an end 2a of this valve body is connected in said body 1 integratedly, and has tapped hole 2h on the end wall 2b of the other end, and said valve body comprises valve seat 21 and spool 22; Sewage draining exit 3; The embolism 4 that cooperates with said tapped hole, said it is characterized in that, said sewage draining exit 3 is positioned at the side of valve body 2; Said valve seat 21 is positioned at body 1 inboard and is fixed in the inwall of said valve one end 2a; Link together via spring K between the end wall 2b of the other end of said valve body and the said spool 22, said spool 22 can move up and down with spring K.
The spring ratio of said spring is scheduled to; When pressure that spool 22 receives surpasses under the situation of predetermined value; Spring pressurized and being compressed blowdown valve 10 is opened, thereby dirt can flow out in the sewage draining exit 3 or flow among the valve body the other end 2b.When the suffered pressure that surpasses predetermined value disappeared, spring returned to original state, thereby spool 22 moves up and closed said blowdown valve 10.The state of closing and opening of said blowdown valve 10 is shown in Fig. 2 (a) and 2 (b).As above, can realize automatic pollution discharge, and need not the artificial blowdown valve that opens and closes.
In addition; Tapped hole 2h among the said end wall 2b and embolism 4 screw-thread fit; And sealed this tapped hole 2h, if accumulate in the height that the dirt of valve body bottom has exceeded sewage draining exit 3 lower edges, dirt can flow out from sewage draining exit 3; Through embolism 4 is removed from tapped hole 2h, also can the dirt of this valve body bottom be discharged.As above, can not cause the obstruction of valve body, can guarantee the unobstructed of blowdown.
Should be noted that the utility model is not limited to the foregoing description, and can carry out various modifications, as long as be no more than the scope and the main idea of the utility model.
Claims (2)
1. a blowdown valve comprises: straight-through body; Valve body, an end of this valve body is connected in said body integratedly, and has tapped hole on the end wall of the other end, and said valve body comprises valve seat and spool; Sewage draining exit; Embolism with said tapped hole cooperates is characterized in that:
Said sewage draining exit is positioned at the side of valve;
Said valve seat is positioned at the body inboard and is fixed in the inwall of said valve body one end;
