Description

Atomizer

The utility model is a kind of spraying machine, mainly provide a kind of easy to assembly, part changes easily, low-cost structure, establishes a commercially available check valve in valve seat.

The spraying water feeding machine generally is used in the cleaning of vehicle, family's door and window, reach the spray medicine operation of orchard, farmland, flowers, and how as shown in Figure 4 the pattern of the water feeding machine of generally spraying, drive 50 pressurizations of one group of pressue device by a motor, water is introduced by the water inlet housing 52 of spraying machine 51, sent via following 53, the delivery port 541 at the seat of honour 54.Because when delivery port 541 is closed, pressue device 50 still continues pressurization and causes the excessive damage of the seat of honour 54 pressure, or force compression cylinder to do and undermine motor, so in the seat of honour 54, establish a pressure relief device, water can be disengaged from the pressure release delivery port 542 of top, to reduce the too much pressure in 54 inside, the seat of honour, so the design of the pressure relief device of spraying machine 51 is very important.

And that the structure of existing spraying machine 51 has is varied, wherein also got permission novel patent in Taiwan, be illustrated in figure 5 as application case number the 7320124 No. " safety valve automatic decompression device ", Fig. 6 and append one for " automatic decompression device of high voltage power spraying machine " second case of application case number the 7620341 No. four, both structure differences, to reach effect identical in institute, but respectively have it not improve part to the greatest extent.

Below promptly at both structure, action and disappearance thereof are done some explanations: as shown in Figure 5,60 water inlets 61 flow in the valve chamber 62 at the seats of honour 60 water through pressurizeing from the seat of honour, hold in the outlet pass 632 inflow valve seats 63 of body 631 peripheries via valve seat 63 tops again, then back down the interior steel ball 634 that is held by decorative pearl on top of an official cap spring 633, flow through the again through hole 635 of valve seat 63 belows, then disengage water spray from delivery port 64, when delivery port 64 is closed, pressue device still continues pressurization, so current still continue to flow into, and when the hydraulic pressure in the valve chamber 62 surpasses top pressure and adjusts the pressure that spring 65 sets, promptly can push pressure release steel ball 66 open, passage 671 away from baffle ring 67, and expose the space, the current passage 671 of flowing through is disengaged from the discharge opening 68 of top again,, make complete set of valves seat 63 be subjected to down the hydraulic pressure of side valve chamber 62 and rise and hold steel ball 66 to reduce the pressure in the valve chamber 62.

Yet, in sending the water process because constantly to 633 punching presses of decorative pearl on top of an official cap spring, cause elastic fatigue and can't shore interior steel ball 634 and the generation drainage, make that the valve chamber 62 of valve seat 63 belows can't pressure accumulation, so that can't ejection steel ball 634, the pressure release effect is had a greatly reduced quality, this elastic fatigue no doubt is normal physical phenomenon, but because decorative pearl on top of an official cap spring 633, interior steel ball 634 is arranged in the valve seat 63, and the upper end is again holding body 631 sealing, so when the defunctionalization of check valve, complete set of valves seat 63 must be eliminated and change, but, must just can buy this product to the dealer because this kind valve seat 63 nonstandard products can't be pulled down replacement from the elsewhere temporarily, the place of right working power spraying machine mostly is the rural area, on the mountain, treat to buy valve seat back, probably will pass through a lot of days, and middle essential pause work, so quite do not meet timeliness, and because its nonstandard product so price is also quite high, is undoubtedly a kind of burden to the consumer.

And another kind of spraying machine pressure relief as shown in Figure 6, water through pressurization flows into first valve chamber 72 from water inlet 71, push below valve plate 82 open via the valve opening on the valve seat 80 81 and flow into second valve chamber 73, the perforation 83 from valve seat 80 peripheries then flows in the valve seat 80, passage 741 by the water outlet housing 74 of below flows out again, when closing passage 741, pressue device continues pressurization, when hydraulic pressure increases to a certain degree, promptly the steel ball 75 of top can be pushed away spacer ring 76 water is released, so far, the pressure in first valve chamber 72 just reduce, the shuttle body 84 that is held in steel ball 75 belows then is subjected to second valve chamber, 73 interior pressure and pushes against, and rises with steel ball 75.And this shuttle body 84 is to rely on the stopper 841 that is convexly set in the both sides, top to be equipped in valve seat 80 tops, falls in the valve seat 80 to prevent shuttle body 84.When shuttle body 84 up during ejection, can rely on stopper 841 to be stuck in spacer ring 76 bottoms again, as placing restrictions on of one stroke.No matter but this stopper 841 is directly to pass to be positioned shuttle body 84, perhaps both sides are welded in respectively on the shuttle body 84, in the process of processing, because personnel handle the not contour situation of stopper 841 inclinations that the problem of factor or processing equipment, tool itself all can cause the left and right sides, cause shuttle body 84 slight inclination and can't lifting displacement in valve seat 80 smooth-goingly.

On the other hand, because its assembly comprises spacer ring, shuttle body, valve seat, valve plate and spring etc., member is various, and except spacer ring, other assemblies need to be installed by the housing below, cause installing to be difficult for.

And above-mentioned two kinds of spraying machine pressure reliefs of having got permission patent all have a common ground, be that it is all speciality in order to the valve body that lifting holds the top steel ball, must be former during damage the valve body made of factory could adapted, its cost an arm and a leg and must wait to buy after could replace, and cause procrastinateing in the work, quite uneconomical.

For improving the disappearance of above-mentioned existing spraying machine pressure relief, main purpose of the present utility model is to provide a kind of spraying machine device of improvement, it have assembling easy, cheap, be easy to change to avoid characteristics such as work delay.

For achieving the above object, the utility model provides a kind of spraying machine device of improvement, the main opening valve chamber up of establishing in the seat of honour of spraying machine, the valve chamber top is sealed by a upper shell with discharge opening, and the upper shell top connects and establishes one and adjust seat, adjust and establish an adjustment spring in the seat, to suppress a steel ball valve, and this steel ball valve below is equipped in a passage that supports ring of being located at the valve chamber top, be provided with a passage that communicates with seat of honour intake chamber in valve chamber top one side in addition, a chamber that communicates with delivery port is then established in the valve chamber bottom, and in valve chamber, be provided with the valve seat of a liftable displacement, be provided with in the valve seat to hold spring and hold the check valve of catch, be provided with passage in the valve seat top in addition, the passage periphery also is provided with the radially valve opening that several run through, the valve seat top also is provided with push rod to be held in the steel ball of top, its characteristics are that the downward one of the passage of valve seat extends the appearance valve chamber of a downwardly facing opening, the internal diameter that holds valve chamber is bigger, its inside from top to bottom is arranged with check valve and spring successively, check valve top periphery outwards is convexly equipped with a horizontal flanges, the sheathed more outward leakproof collar of horizontal flanges, and spring is to be held between the horizontal flanges and leakproof collar below and chamber of check valve, other is a sheathed collar in the valve chamber stage casing, the top of the collar is equipped in the root edge to ring, the bottom then is equipped in the valve chamber inwall, and keep a suitable distance with the lower shaft hole perisporium of valve seat, and collar internal diameter is less than the lower shaft hole perisporium external diameter of below, in addition in the cover peripheral wall establish one with the involutory radial direction through hole of passage of valve chamber.
