Abstract
The utility model discloses a local valve body replaceable long-service life gate valve. The gate valve comprises a valve body (1) and a valve plate (2), wherein the valve plate (2) is located inside the valve body (1), a yield hole matched with the valve plate (2) is formed in a seat of the valve body (1), a close plate (3) for closing the yield hole is arranged on the yield hole, and is connected with the valve body (1) through a connecting device. According to the gate valve disclosed by the utility model, the stroke of the close plate is adjusted to prevent the wear on the sealing valve body and the valve seat caused by overlarge opening and closing force in an opening force of the valve plate; simultaneously, the service life of the gate valve can be prolonged by replacing the close plate.
Description
Technical field
The utility model relates to gate valve, especially relates to the valve body of gate valve.
Background technique
Gate valve is one of most widely used valve in the various fluid conveying engineerings, uses as cut-off device on the fluid pipe-line of industries such as building, urban environmental protection, petrochemical industry, medicine, food, metallurgy, weaving, electric power.The tradition Gate-valve sealing is bad, hard seal gate valve particularly, and the seal valve seat between valve body, the valve plate generally all is Cuprum alloy, not during complete shut-down, sealing surface of valve plate wearing and tearing or damage are all very serious at gate valve.The wear extent that valve body, valve plate seal valve seat move up and down is big, and Gate-valve sealing was lost efficacy, and valve body, valve plate shorten working life greatly.
The model utility content
The purpose of this utility model is to solve traditional gate valve body, valve plate and valve seat to cause short problem in working life because of wearing and tearing.
For addressing the above problem, the technical solution adopted in the utility model is: valve body local replacing formula long lifetime gate valve, comprise valve body and the valve plate that is positioned at valve body, the valve body that it is characterized in that described valve plate below is provided with the yielding hole adaptive with valve plate, below, described yielding hole is provided with the shrouding of making a concession the hole for shutoff, and described shrouding connects valve body by connection set.
Above-mentioned connection set comprises the fixed base that is connected with valve body, described fixed base is provided with pilot hole, the outer end of pilot hole is screw, be provided with adjustable lever in the pilot hole, adjustable lever one end and shrouding are connected, the other end adjusting bolt that is threaded, the outer end screw scyewed joint of regulating bolt and pilot hole.
The beneficial effects of the utility model are: by the stroke adjustment of bolt to shrouding, can prevent effectively that valve plate is in the process of opening, because of the excessive wearing and tearing to sealed valve body and valve seat of hoisting capacity; Simultaneously by changing the working life that shrouding can prolong gate valve greatly.
Description of drawings
Fig. 1 is the utility model schematic representation.
Fig. 2 is C place enlarged diagram among Fig. 1.
Shown in the figure: 1 valve body, 2 valve plates, 3 shroudings, 7 adjustable levers, 8 fixed bases, 9 regulate bolt, 10 seal rings.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2, select preference that the utility model is described further.
As shown in Figure 1 and Figure 2, valve body local replacing formula long lifetime gate valve, comprise valve body 1 and the valve plate 2 that is positioned at valve body 1, offer the yielding hole adaptive with valve plate 2 on valve body 1 base, make a concession the hole and be positioned at valve plate 2 belows, make a concession the below, hole and be provided with the shrouding 3 of making a concession the hole for shutoff, shrouding 3 is steel plate, shrouding 3 connects on the valve body 1 by connection set, and shrouding 3 is positioned.When wearing and tearing with valve plate 2, shrouding 3 can change shrouding 3, thus the working life of realizing the prolongation gate valve.Connection set can have multiple mode, can be to be welded on the valve body 1, and can be to be riveted on the valve body, can be connected on the valve body 1 by bolt, also can be that other modes connect.The connection set of present embodiment as shown in Figure 2, it comprises the fixed base 8 that is connected with valve body, it is that casting is connected as a single entity in the time of also can producing with valve body 1 that fixed base 8 can be welded on valve body 1, fixed base 8 is provided with pilot hole, the outer end of pilot hole is tapped hole, pilot hole is positioned at the below of making a concession the hole, be provided with adjustable lever 7 in the pilot hole, adjustable lever 7 can be shifted up and down along pilot hole, adjustable lever 7 one ends and shrouding 3 are connected, the other end is threaded and regulates bolt 9, the outer end screw scyewed joint of regulating bolt and pilot hole.Be provided with the seal ring 10 for liquid sealing between adjustable lever 7 and the fixed base pilot hole, prevent medium remittance leakage.
The utility model is work like this: when shrouding leaks because wearing and tearing produce, rotating bolt 9 makes adjustable lever 7 drive shrouding 3 and moves up in the vertical direction, reaches and adjusts valve plate 2 to the stroke between the valve body 1, thereby make the local replacing of valve body, prolong the working life of valve body.The travel position of adjusting adjustable lever when gate valve assembles gets final product.If wearing and tearing cause sealing to go wrong, only need to adjust the shrouding position or change shrouding.
Claims (4)
1. valve body local replacing formula long lifetime gate valve, comprise valve body (1) and be positioned at the valve plate (2) of valve body, the valve body (1) that it is characterized in that described valve plate (2) below is provided with the yielding hole adaptive with valve plate (2), below, described yielding hole is provided with the shrouding (3) of making a concession the hole for shutoff, and described shrouding (3) connects valve body (1) by connection set.
2. valve body local replacing formula long lifetime gate valve according to claim 1, it is characterized in that described connection set comprises the fixed base (8) that is connected with valve body, described fixed base (8) is provided with pilot hole, the outer end of pilot hole is screw, be provided with adjustable lever (7) in the pilot hole, adjustable lever (7) one ends and shrouding (3) are connected, and the other end is threaded and regulates bolt (9), the outer end screw scyewed joint of regulating bolt (9) and pilot hole.
