Abstract
The utility model relates to an electro-hydraulic insertion plate type cinder valve, which comprises valve bodies and valve plates arranged between the valve bodies, wherein the upper valve plate is provided with a control hand wheel, electro-hydraulic push rods are arranged on the rest valve plates, at least three sealing elements positioned between the valve bodies and the electro-hydraulic push rods are arranged on the valve plates, the first sealing element is a wear-resistance steel sealing strip, and the rest sealing elements are silicon rubber sealing strips. The electro-hydraulic insertion plate type cinder valve is provided with at least three sealing elements, wherein the first sealing element is the wear-resistance steel sealing strip, and bead-shaped dust on the valve plates is effectively removed, so the damage to the later silicon rubber sealing strips is eliminated, powdery dust can be effectively sealed through the later sealing strips, and good sealing performance is realized.
Description
Technical field
The utility model relates to a kind of electricity spile type unloading valve that surges, and belongs to the control valve technical field.
Background technique
The existing electricity spile type unloading valve that surges comprises valve body and is arranged on valve plate between each valve body, and last valve plate is provided with the control handwheel, and all the other valve plates are provided with Electrohydraulic push rod; During work, last valve plate is a normally open valve, generally is passing through valve plate on the control handwheel rotary closing under the situation of overhauling or meeting an urgent need; All the other valve plates are the work valve plate, open valve plate by the Electrohydraulic push rod circulation, carry out the repetition discharging, establish Sealing between work valve plate and the Electrohydraulic push rod, existing Sealing is together, be generally soft Sealing, Sealing also has excellent sealing performance when just starting working, after long-time the use, because the dust that some particles are bigger in travel fatigue meeting and Sealing bump, rub, long this can cause Sealing to damage, and influences sealability, phenomenons such as dirt appear leaking out, letting out, serious harm worker's healthy and befouling environment.
The model utility content
The utility model is at above-mentioned defective, and purpose is to provide a kind of electricity that can have good seal performance for a long time spile type unloading valve that surges.
The technical solution of the utility model is: the utility model comprises valve body and is arranged on valve plate between each valve body, last valve plate is provided with the control handwheel, all the other valve plates are provided with Electrohydraulic push rod, valve plate is provided with the three seals spare at least between valve body and Electrohydraulic push rod, the first road Sealing is the Wear Resisting Steel Stamping Steel Ribbon, and all the other Sealings are silastic sealing strip.
The upper and lower end of valve plate is established top board and press table, last press table fixing seals.
The utility model has the advantages that: the utility model has been established three seals spare at least, wherein the first road Sealing is the Wear Resisting Steel Stamping Steel Ribbon, effectively root out the bead dust on the valve plate, so just eliminated infringement to road, back silastic sealing strip, the Stamping Steel Ribbon in back road can play excellent sealing performance effectively with the sealing of powdery dust.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that valve body, 2 is that Wear Resisting Steel Stamping Steel Ribbon, 3 is that silastic sealing strip, 4 is that top board, 5 is that press table, 6 is that valve plate, 7 is a U type Sealing among the figure.
Embodiment
The utility model comprises a plurality of valve bodies 1 and is arranged on valve plate 6, U type Sealing 7 between the adjacent valve body 1, and the utility model comprises four valve bodies 1 and three valve plates 6, and valve plate 6 one ends of its middle and upper part connect the control handwheel; The middle part is connected Electrohydraulic push rod with valve plate 6 one ends of bottom, establish Sealing between the valve plate 6 of middle part and bottom and the Electrohydraulic push rod, the utility model is selected three seals spare for use, wherein the slubbing Sealing is a Wear Resisting Steel Stamping Steel Ribbon 2, back twice are silastic sealing strip 3, the three seals bar is all realized fixing by the top board 4 and the press table 5 that are arranged on valve plate 6 upper and lower sides, though when each Stamping Steel Ribbon is subjected to impacting the back adjustment for a long time or changes, can regulate by top board 4 and press table 5 realizations.
Claims (2)
1. the electricity spile type unloading valve that surges, comprise valve body and be arranged on valve plate between each valve body, last valve plate is provided with the control handwheel, all the other valve plates are provided with Electrohydraulic push rod, it is characterized in that, valve plate is provided with the three seals spare at least between valve body and Electrohydraulic push rod, and the first road Sealing is the Wear Resisting Steel Stamping Steel Ribbon, and all the other Sealings are silastic sealing strip.
