Abstract
The utility model relates to a brake valve which can prevent foreign matters from accumulating in the valve cavity. The brake valve comprises a valve handle, a valve body, a valve plate and a spring. The valve body is composed of a right valve body and a left valve body which are connected through a bolt; the valve plate is actively connected with the valve handle; a midbody is arranged between the left valve body and the right valve body; the valve plate provided with a through hole is arranged inside the midbody. The utility model improves the structure of a current valve plate; when the brake valve is open, the through hole on the valve plate aligns with the passage of the brake valve, foreign matters can pass through the through hole; under the effect of the spring, the valve plate seals the valve cavity all the time, so foreign matters can not get into the valve cavity, thus ensuring tight and reliable sealing when the valve is closed. The brake valve solves the problem of the accumulation of the foreign matters in the valve cavity without manual work and a foreign matter removal device; the brake valve is economic and practical, simple in structure and convenient to maintain, and is serialized and can be installed on the mouth of various pipes.

The interior right side of body is provided with plate washer in described, is provided with the single valve plate between plate washer and the left valve barrel, and the single valve plate is provided with through hole, and plate washer is provided with through hole, is provided with spring between plate washer and the right valve barrel, and plate washer internal diameter and right valve barrel external diameter junction are provided with seal ring.
Be provided with left valve plate and right valve plate in the body in described, and between left valve barrel and right valve barrel, left side valve plate is provided with left through hole, right valve plate is provided with right through hole, valve rod is arranged between the groove of left valve plate and right valve plate inside upper part, spring is arranged in the groove of left valve plate and right valve plate lower inside, and left valve plate internal diameter and right valve plate external diameter junction are provided with seal ring.
The through hole of described single valve plate is concentric with the through hole of plate washer, and internal diameter equates and be corresponding.
The left through hole of described left valve plate is concentric with the right through hole of right valve plate, and internal diameter equates and be corresponding.
The positive beneficial effect that the utility model had:
1. improved existing valve board structure, valve plate is provided with through hole, and when gate valve was in opening state, the through hole of valve plate was over against the gate valve passage, and foreign material can pass through from through hole;
2. because valve plate is sealing valve pocket all the time under the effect of spring, foreign material can't enter, thereby it is tight to put in place when having guaranteed valve closing, and sealing is reliable;
3. solved thoroughly that foreign material are long-pending to slip in the problem of valve pocket, do not needed artificial and device clear foreign material device, economical and practical;
4. simple in structure, easy to maintenance, specification seriesization is installed and used applicable to various pipeline opening.

Embodiment
Embodiment 1
Consult shown in Figure 1, the gate valve of the long-pending foreign material of a kind of anti-valve pocket, present embodiment is the single valve plate structure, mainly comprises formations such as valve rod 1, left valve barrel 2, middle body 3, single valve plate 4, right valve barrel 5, baffle plate 6, spring 7, seal ring 8, bolt 9; Its left valve barrel 2 connects by bolt 9 with right valve barrel 5, body 3 in being provided with therebetween, right sides are provided with plate washer 6 in the middle body 3, be provided with single valve plate 4 between plate washer 6 and the left valve barrel 2, single valve plate 4 is provided with through hole 401, plate washer 6 is provided with through hole 601, and through hole 401 is concentric with through hole 601, and internal diameter equates and be corresponding; In single valve plate 4 upper end slot valve rod 1 is set, for activity connects, and valve rod 1 therefrom passes on body 3 tops; Be provided with spring 7 between plate washer 6 and the right valve barrel 5, baffle plate 6 can horizontally slip under the effect of spring 7, be pressed on right valve barrel 5 and single valve plate 4 is pressed on the left method conjuncted 2 with suitable power, plate washer 6 internal diameters and right valve barrel 5 external diameter junctions are provided with seal ring 8 sealings.
Consult shown in Figure 2ly, present embodiment is the bivalve plate structure, by single valve plate 4 and the plate washer 6 in left valve plate 10 and the right valve plate 11 bivalve plate alternate embodiments 1; Its left valve barrel 2 connects by bolt 9 with right valve barrel 5, body 3 in being provided with therebetween, be provided with left valve plate 10 and right valve plate 11 in the middle body 3, and between left valve barrel 2 and right valve barrel 5, left valve plate 10 is provided with left through hole 1001, right valve plate 11 is provided with right through hole 1101, described left through hole 1001 is concentric with right through hole 1101, and internal diameter equates and be corresponding that valve rod 1 is arranged between the groove of left valve plate 10 and right valve plate 11 inside upper part, and valve rod 1 therefrom passes on body 3 tops, for activity connects; Spring 7 is arranged in the groove of left valve plate 10 and right valve plate 11 lower inside, and left valve plate 10 internal diameters and right valve plate 11 external diameter junctions are provided with seal ring 8 sealings; Left side valve plate 10 can horizontally slip under the effect of spring 7 with right valve plate 11, is pressed on left valve barrel 2 and the right valve barrel 5 with suitable power, adopts the bivalve plate structure to make valve closing tighter.
Working principle of the present utility model: during pulling valve rod 1, drive single valve plate 4 or left valve plate 10 and right valve plate 11, when through hole 401 and through hole 601, or left through hole 1001 and right through hole 1101 are over against left valve barrel 2 during with right valve barrel 5 passages, gate valve becomes full open position, when valve rod 1 moves round about, through hole 401 and through hole 601 or left through hole 1001 and right through hole 1101 stagger with left valve barrel 2 and right valve barrel 5 passages gradually, when staggering fully, when the other parts of single valve plate 4 or left valve plate 10 and right valve plate 11 were sealed left valve barrel 2 fully with right valve barrel 5 passages, gate valve became closed condition.
Because single valve plate 4 or left valve plate 10 and right valve plate 11 are under the effect of spring 7, left valve barrel 2 is close on the left side, plate washer 6 and right valve barrel 5 are close in the right, no matter open or closed condition under, but single valve plate 4 or left valve plate 10 and right valve plate 11 all complete closed valve pocket, foreign material and through hole 401 and through hole 601 in the gate valve passage, or the foreign material in left through hole 1001 and the right through hole 1101 all can't enter valve pocket, thus guaranteed gate valve close put in place tight.
