Abstract
A totally enclosed distributing gate valve solves such problems of a gate valve adopting an unenclosed structure as dust and gas leakage, environmental pollution, difficult opening and closing, serious abrasion and short service life. The gate valve is characterized by comprising a valve body (1), a valve plate (2), a valve cap (6), a valve rod (7) and a handwheel (8); a roller (3) is arranged on the valve plate (2) in the valve body (1); a roller bearing (4) is arranged between the valve plate (2) and the roller (3); and fillers (5) are filled at the friction part of the valve plate (2) and the valve body (1). The utility model has the advantages of simple structure, good tightness, flexible opening and closing and long service life, and is applicable to industries such as power, metallurgy, chemical engineering, mines and the like.
Description
Technical field
The utility model belongs to the technical field of machine-building, is specifically related to a kind of totally-enclosed cloth push-pull valve.Be applied to industries such as electric power, metallurgy, chemical industry, mine.
Background technique
Totally-enclosed cloth push-pull valve is a kind of industries such as electric power, metallurgy, chemical industry, mine that are widely used in, and regulates the flow of blanking and the special device that cuts off blanking.Because applying working condition is abominable, medium contains a large amount of dust, so just requires institute's use push-pull valve can satisfy the condition of operating mode complexity, wear-resistant and anti-washing away, and reach the needs of environmental protection.But just known to the inventor, the employed push-pull valve of every profession and trade is non-enclosed structure at present, a large amount of dust and dirt gas leakage in environment on every side, the requirement that does not reach environmental protection equipment; Medium is full of whole body cavity behind the valve closing, causes the valve opening difficulty; Medium is to the wearing and tearing of valve and wash away seriously, and valve is short working life.
Summary of the invention
The purpose of this utility model is exactly in order to remedy above deficiency, a kind of can in feeding system, frequently use that provides, and wear-resistant and abrasion resistance can be good, prevents dust pollutions that leak outside, and protects environment, the totally-enclosed cloth push-pull valve that increases the service life.
The utility model is to adopt following technological scheme to realize: described totally-enclosed cloth push-pull valve, form by valve body (1), valve plate (2), valve gap (6), valve rod (7), handwheel (8), it is characterized in that the valve plate (2) in the valve body (1) is provided with roller (3), be provided with roller bearing (4) between valve plate (2) and the roller (3), valve plate (2) is provided with filler (5) with valve body (1) friction place.Full-closed structure is adopted in design, does not have a large amount of dust or dirt gas when guaranteeing medium by valve and drains to outward in the environment on every side, and the rectangle packing seal is adopted in valve plate and valve body friction place, good sealing effect, prevention environmental pollution.During use, valve plate by the roller holder all the time, and force of rolling friction is quite little, opens and closes flexibly, and improve working life greatly; Valve rod adopts big helical pitch helical design, and keying speed is fast; In order to improve the wear-resistant of valve and abrasion resistance energy, adopt the good material of wear resistance, the life-span of valve is more than doubled.
Totally-enclosed cloth push-pull valve of the present utility model has simple in structure, and good airproof performance opens and closes flexibly, has wide range of applications, and the advantage of long service life has improved the usability of like product greatly.
Description of drawings:
Accompanying drawing 1 is totally-enclosed cloth push-pull valve plan view structural drawing
Accompanying drawing 2 is totally-enclosed cloth push-pull valve side view structural drawing
Among the figure: 1, valve body, 2, valve plate, 3, roller, 4, roller bearing, 5, filler, 6, valve gap, 7, valve rod, 8, handwheel.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, and totally-enclosed as shown in drawings cloth push-pull valve comprises valve body 1, valve plate 2, roller 3, roller bearing 4, filler 5, valve gap 6, valve rod 7, handwheel 8.Valve body 1 is formed a fully closed cavity with valve gap 6, and valve plate 2 is in valve gap 6 cavitys behind the valve opening, and valve plate 2 is in valve body 1 cavity behind the valve closing.No matter valve plate 2 is opened or closed, the upper flange of valve body 1 and valve plate 2 with filler 5 sealings, prevent that dust and dirt gas leakage are in valve gap all the time.Laying roller 3 in the body cavity of valve body 1 and valve gap 6 holds valve plate 2, roller 3 contacts with valve plate 2 all the time, valve opening or when closing, force of rolling friction is quite little, the keying of valve is very flexible, solves particularly the problem that when valve closing a large amount of material is pressed in valve opening difficulty on the valve plate 2.Valve rod 7 adopts big helical pitch helical design, and keying speed is fast.In view of medium to the washing away and serious wear of valve, the material of valve adopts wear-resisting steel plate, and can be brought up to more than 1 year working life.
