Abstract
The utility model relates to a gate valve with blowing valves, which comprises a valve body, a valve seat, a valve cap, a valve rod, a gate plate, a handwheel, a sealing member and an installation member. Blowing valves are arranged at the upper side of the valve cap and the concave pit position of the valve body. High pressure water or steam led from the blowing valve on the valve cap under the condition of installing the valve expels from the blowing valve in the concave pit position of the valve body, and the utility model realizes that the slag in a concave pit of the valve body can be removed in an on-line mode, and has the advantages of convenient removal of the slag, time-saving removal of the slag, etc.
Description
Technical field
The utility model relates to a kind of gate valve.
Background technique
The structure of gate valve mainly contains formations such as valve body, valve seat, valve gap, valve rod, flashboard, handwheel, gate valve in use some easy precipitation mediums, slag etc. is deposited on the pit of valve body easily, these precipitated solid particle slags can produce wearing and tearing to valve sealing face, influence the sealability and the working life of valve, so will regularly remove to the slag in the valve body pit.After common gate valve need unload valve, could remove the slag in the valve body pit, can not onlinely remove.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of slag in can online removing valve body pit is provided, and removes that slag is convenient, the gate valve of timesaving band blow down valve.
The technological scheme that realizes the utility model purpose comprises valve body, valve seat, valve gap, valve rod, flashboard, handwheel and Sealing and assembling set, mainly is to be respectively equipped with blow down valve at valve gap upside and valve body pit.
The utility model beneficial effect compared with prior art is: be respectively equipped with blow down valve at valve gap upside and valve body pit, under the valve installment state, can feed high pressure water or steam from the blow down valve on the valve gap, discharge from the blow down valve of valve body pit, realize the slag in the online scavenging valve body pit, have advantages such as the slag of removing makes things convenient for, saves time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
The gate valve of band blow down valve as shown in Figure 1, comprise valve body 1, valve seat 2, valve gap 4, valve rod 5, flashboard 3, handwheel 7 and Sealing and assembling set, be respectively equipped with blow down valve 6,8 at valve gap 4 upsides and valve body 1 pit, enter high pressure water or steam by blow down valve 6, the sediments in valve body 1 pit is discharged from blow down valve 8.
