Description

Spraying two waters chews

The utility model relates to a kind of improved mesolow valve, and particularly a kind of service water is easily chewed.

Existing service water chew mainly by valve body, valve pad, valve gap, gland, valve rod etc. totally nine kinds of parts to form now on the market that the water of sale chews be exactly this form, existing from a structural point water is chewed and is belonged to the stop valve class, can only control and close water flowing and chew, flow and pressure that can not fine tuning water.Function singleness, inconvenience uses, is unfavorable for using water wisely, also exists to fit badly or close incessantly gland common fault such as leak simultaneously.

The purpose of this utility model provides a kind of existing spraying function has spray two waters of trickle function to chew again, chews and defect such as fits badly but also will overcome aforementioned existing water.

Structure of the present utility model such as following is seen on the whole, and described spray two waters are chewed and comprised the two large divisions: valve body (9) and awl core (10); Valve body (9) is the T font structure, and a valve body hole (1) is arranged on it, and awl core (10) places in valve body (9) chamber, and with sealing ring (11) and nut locking, there is a circular trough (4) lower end in valve body (9) chamber; There is leader (8) awl core (10) upper end, awl core (10) central authorities have water injection nozzle (2), awl core (10) middle part external cylindrical surface has trickle groove (5), the another side at middle part has hole for water spraying (6), also having one side is the conical surface (7), trickle groove (5), water injection nozzle (6), the conical surface (7) three is on same awl core, and be the concentric circles cylinder, the three is the hexagonal angle distribution mutually on awl core (10) cross section, the trickle that is uniform-distribution with some roundlet arc straight troughs compositions between awl core (10) bottom external cylindrical surface and valve body (9) the chamber inner cylinder face is chewed (3), it is 20-25 that this trickle is chewed straight trough quantity, its cross sectional shape is the R=0.5-1 semicircular arc, and straight trough is about 4-6mm.

It is like this that described water is chewed the course of work: the press water from pipe-line system flows into through valve body hole (1), carry out flow at the conical surface (7), rotating handles (8), if trickle groove face (5) cooperates with valve body hole (1), then press water will flow into cannelure (4), the trickle of forming by the some little garden arc groove between garden cylinder and the interior garden of valve body (9) cylinder outside awl core (10) end is chewed (3) outwards water spray at last, form several slender threads formula current, this water flow impact pressure is big, shock surface can structurally be adjusted, continue rotating handles (8) with the needs that adapt to different occasions, if hole for water spraying face (6) cooperates with valve body hole (1), then press water is realized big flow water spray through water injection nozzle (2), and this function belongs to fast-open type, but also can regulate pressure and flow.Continue rotating handles (8) again, then the conical surface (7) cooperates with valve body hole (1), and realize by function in the cut-out pressure water route, and this device handle (8) can be transferred choosing arbitrarily at 360 °.

This invention with have water now and chew to compare and have following advantage: have water spray and two kinds of functions of trickle, pressure and flow all can be regulated continuously, easy to operate, handle can rotate arbitrarily in 360 °, cost is low, and number of parts is reduced to present 4 kinds by original nine kinds, and this invention has obvious practicability, not only daily life be can be used for, industrial or agricultural and the required occasion of other industries also can be used for.

Introduce an a kind of embodiment of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing 1 is described example structure cutaway view.

(1) is valve body hole among the figure, (2) be water injection nozzle, (3) chew for trickle, (4) be cannelure on the valve body (9), (5) be the trickle groove, (6) be hole for water spraying, (7) be the conical surface, (8) be handle, (10) be the awl core, (11) be sealing ring, (12) have water injection nozzle (2) for nut awl core (10) central authorities, and the outer garden of awl core (10) post simultaneously has trickle groove (5), another side has and sprays not hole (6) to also have one side be a conical surface (7), trickle groove (5), hole for water spraying (6), the conical surface (7) three is on same awl core and be concentric garden cylinder, is hexagonal angle distribution (see figure 3) mutually on awl core (10) cross section, the trickle that is uniform-distribution with some little gardens arc straight trough composition between garden cylinder and the interior garden of valve body (9) cylinder outside awl core (10) end is chewed (3), trickle is chewed about 20～24 of straight trough quantity, and cross sectional shape is R=0.5～1 half garden arcs, and straight trough is about 4～6mm.

Fig. 2 is Fig. 1 water outlet end construction cutaway view.

Fig. 3 is trickle groove (5), hole for water spraying (6), the conical surface (7) cross section view.

Described utility model is suitable for pressure at 4～6kg/cm ², temperature is lower than 120 ℃ occasion use, and trickle is chewed groove can use the push broach one-shot forming, valve body, awl core can be cast, and have only a small amount of machined, and material can be used cast copper, also can be cylinder iron, but lining teflon plastics within it, the quality of fit requirement when reducing the processing conical surface.
