Abstract
The utility model relates to the technical field of valves, in particular to an anti-clogging blowndown valve, which comprises a water inlet interface, a main pipe body, a water outlet interface and a side pipe body, wherein the head and the tail of the side pipe body are both communicated with the main pipe body; a bent pipe is arranged on the side pipe body; and a blowndown opening is formed at the bottom of the bent pipe. The anti-clogging blowndown valve with a simple structure is easy to produce and popularize and has great production and practical significance.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of blowdown valve.
Background technique
As everyone knows, the valve that blocks class mainly contains gate valve, stop valve, stopcock, ball valve, butterfly valve, needle type valve, membrane valve etc., blowdown valve then is to be developed and come by wherein gate valve, and its principle is for utilizing the gear 90-degree rotation, thereby promotes to realize opening and closing with ovable valve stem; Blowdown valve relies on its simple in structure, good airproof performance, and volume is little, material consumption is few, particularly driving moment is little, and is easy and simple to handle, realizes that easily fast opening and closing is widely used in manufacturing enterprise and the daily life.
But, because the effect of blowdown valve is mainly used in discharging liquid or lime-ash with impurity, and the frequency of cleaning is also fewer after installing, so that situation about stopping up often appears in blowdown valve; If stopping up appears in blowdown valve, because the general mounting point of blowdown valve is comparatively hidden, dredging work also is not easy to operation.
Blowdown valve operated by rotary motion in the market has the blind pipe structure, ducted solid matter can flow into blind pipe by nature during blowdown like this, after after a while, will amass full solid matter in the blind pipe, if stop up, need to open blowdown valve, then the solid matter in the blind pipe is dredged, such structure has following defective:
1 blind pipe, one end and valve communicate, and the other end then is designed to enclosed construction, if the time is more of a specified duration, solid matter is piled up more, also are difficult for all solids thing is removed even if open valve.
If 2 want to remove the solid matter of accumulation, then need to open valve, increased operation easier, generally need the maintenance man of specialty to operate, increased maintenance cost.
So be badly in need of at present a kind of simple in structurely, can not only effectively prevent from stopping up, and the blowdown valve that is easy to dredge after stopping up.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of anti-plugging blowdown valve, comprise into water interface, main pipe, water outlet mouthpiece, also comprise the side pipe body, described side pipe body head and the tail all communicate with described main pipe, described side pipe body is provided with bend pipe, and the bottom of described bend pipe is provided with sewage draining exit.
The horizontal plane of described water outlet mouthpiece is than the low 1cm-1.5cm of horizontal plane of described water inlet interface.
Also be provided with the blowdown cap on the described sewage draining exit.
The beneficial effects of the utility model are: use the utility model, can effectively prevent the phenomenon that drain valve stops up, and be convenient to clear up sewage impurity, reduced the maintenance cost of drain valve, also prolonged the working life of valve, and the utility model is simple in structure, is easy to make, promote, and is of great practical significance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
In the accompanying drawing 1: the 1-interface of intaking, the 2-body is anterior, 3-main pipe, 4-body middle part, 5-body rear portion, 6-water outlet mouthpiece, 7-side pipe body rear portion, 8-sewage draining exit, 9-blowdown cap, 10-bend pipe, 11-side pipe body.
A kind of anti-plugging blowdown valve comprises into water interface 1, main pipe 3, water outlet mouthpiece 6, also comprises side pipe body 11, side pipe body 11 head and the tail all communicate with main pipe 3, the side pipe body also is provided with bend pipe 10, and the bottom of bend pipe 10 is provided with sewage draining exit 8, also is provided with blowdown cap 9 on the sewage draining exit 8.
The horizontal plane of water outlet mouthpiece 6 is than the low 1cm-1.5cm of horizontal plane of water inlet interface 1 in addition, is for when water quality and impurity are fully admixed, and guarantees that the impurity light, more water-soluble than water normally flows away.
The utility model operated by rotary motion is in the drain opening of equipment, the front end that water inlet interface 1 is connected drain opening, water outlet mouthpiece 6 connects the rear end of drain opening, and when with the effluent stream of impurity during through body, sewage at first enters from water inlet interface 1, because the flow velocity of sewage is lower, sewage at first flows into the test tube body, precipitates through bend pipe 10 rear impurities, and impurity accumulates in the lowest part of drain pipe, when the horizontal plane of sewage was higher than the horizontal plane at main pipe rear portion 5, sewage just flowed out from water outlet mouthpiece 6.
If impurity is too much, and fail in time cleaning, the attendant can open blowdown cap 9, emits the impurity of the inside, to guarantee the drain valve normal operation, has not only effectively prevented the obstruction of drain valve, and has solved the problem of difficult cleaning after drain valve stops up.
Utilize technological scheme described in the utility model, or those skilled in the art designing similar technological scheme under the inspiration of technical solutions of the utility model, and reach above-mentioned technique effect, all is to fall into protection domain of the present utility model.
