Description

A kind of water-in and water-out two-way valve

The utility model relates to a kind of water-in and water-out two-way valve that is used for water supply system pond or water tank.

The tap water water storage of existing high-rise building, the water supply installation pond and single tube three valves that are arranged on roof of adopting supply water storage system more; Promptly one is arranged on automatic cut-off inlet valve (generally adopting float valve) in the pond, one and is arranged on and goes out water one-way valve and a water inlet one-way valve that is arranged on bottom of the building at the bottom of the pond, and water is then all finished in same pipeline up and down, with reference to Fig. 3.Can cause following problem owing to go out the existence of water one-way valve at the bottom of the pond: valve closing is not tight, judges the leakage detection difficulty; When the water-filling of pond, not only can produce noise, and because of water impact is entered user's pipeline by sludge at the bottom of the pond of stirring with direct outlet valve at the bottom of the pond, thereby polluted water; On the other hand, such structure is not easy to install, not only consumption material but also when taking a lot of work.

The purpose of this utility model just is to provide at above-mentioned prior art present situation a kind of two-way valve that inlet valve and outlet valve are united two into one.

Design proposal of the present utility model is: the water-in and water-out two-way valve comprises valve body and the spool that is positioned within the valve body inner bore, the valve body middle part has several horizontal intake-outlets, but spool is the easy on and off activity in valve body inner bore, its afterbody passes the center hole of valve body bottom, and its top and valve body inner bore top shape match.For conveniently installing and using, can directly process or connect a hanger in valve body one side, it is terminal hinged with suspension lever middle part, and an end of this suspension lever is aimed at the tail end of spool, and the other end connects floating ball rod.

Better scheme is to increase by an one-way throttle trimmer valve structure on the said structure basis, so that the on-off action of valve is more reasonable: valve body inner bore is laterally having the trimmer valve clutch release slave cylinder under the intake-outlet, its bottom is drilled with throttling pore, spool middle part is one to have the trimmer valve piston of annular groove, analyse and observe and be " worker " font, rubber seal is housed in groove and leaves the moving gap of certain easy on and off string, piston base is drilled with several apertures that directly communicate with groove floor.

Compared with prior art, the utility model utilizes water level pressure reduction to form the principle of siphonage dexterously, replace original two valves of water inlet, water outlet with a two-way valve, need not to leave again the mouth of a river during installation, it is in light weight, cost is low, volume is little, installs very conveniently, and the utility model can be mounted to the hydrocone type structure in use, all valve events is all finished water inlet, the equal ripple disable of water outlet, noise free under the bottom.

Description of drawings:

Fig. 1 is the utility model embodiment's a structure cross-sectional schematic.

Fig. 2 installs and uses example for one of the present utility model.

Fig. 3 is that single tube three valves of the prior art are for the water storage system schematic representation.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, the water-in and water-out two-way valve comprises valve body (1) and is positioned at spool (1) within valve body (3) endoporus, valve body (3) endoporus top is the taper primary valve, valve body (3) upper periphery wall is processed with pipe thread, so that same aqueduct (23) connects (referring to Fig. 2), valve body (3) middle part have horizontal intake-outlet (4) several, as the pond intake-outlet, the part of valve body (3) endoporus under horizontal intake-outlet (4) is the trimmer valve clutch release slave cylinder, its bottom is drilled with throttling pore (8), plays the throttling buffer function; Spool (1) is positioned at valve body (3) but the easy on and off activity, analyse and observe roughly and be " doing " font, its afterbody passes the center hole of valve body (3) bottom, its end is spacing with the nut (9) that is threaded with it, spool (1) top and valve body (3) endoporus top shape match, be main valve, better scheme is a machined grooves and load onto rubber seal (2) thereon, can strengthen sealing, spool (1) middle part is for having the trimmer valve piston (5) of annular groove, analyse and observe and be " worker " font, rubber seal (6) is housed in groove and leaves the moving gap of a certain amount of easy on and off string, piston (5) bottom is drilled with several apertures (7) that directly communicate with groove floor.

As shown in Figure 2, when installing and using, the utility model should combine with a floating ball lever mechanism, and this floating ball lever mechanism should comprise a ball float (22), a connecting rod (21) and suspension lever (11), and the free end of lever (11) is aimed at the tail end of spool (1).For conveniently installing and using, can adopt most preferred embodiment as shown in Figure 1, valve body (1) the middle part the left-hand side directly is shaped on hanger (10), it is terminal hinged by bearing pin (12) with suspension lever (11) middle part, suspension lever (11) is the boundary with the hinged support, and a length of side is short on one side, and its long end end has an aperture in order to connect ball lever (21), with reference to Fig. 2, the tail end of its short end (being free end) end alignment spool (1).(25) are for being arranged on the water inlet one-way valve of bottom of the building among Fig. 2.

Working principle of the present utility model below is described in detail in detail:

With reference to Fig. 2, when the wet pit middle water level is lower than ball float and plays flotation line, under the deadweight effect of ball float (22), connecting rod (21) and suspension lever (11), suspension lever (11) jack-up spool (1), current flow into the pond by main valve through several horizontal intake-outlets (4);

When water has held full arrival ball float and has played flotation line, ball float (22) floating, drivening rod (21) rotates suspension lever (11), decontrols the spool tail end, and spool (1) is closed main valve under the acting in conjunction of deadweight and water supply line water flow pressure;

Cut off the water or hydraulic pressure when low as water factory, promptly produce siphonage owing to exist water-head water tap one to open between the pond water surface and the user's water tap, spool (1) is upwards inhaled automatically to be opened, current enter aqueduct (23) through main valve from the pond again through several horizontal intake-outlets (4) and flow to water tap (24), supply water.

The working principle of one-way throttle formula trimmer valve is: when the trimmer valve piston (5) at spool (1) middle part rises, the clutch release slave cylinder internal volume of valve body (3) endoporus bottom increases, rubber ring (6) is close to the groove below, current enter through piston (5) and clutch release slave cylinder gap location, enter clutch release slave cylinder by rubber ring (6) top several water conservancy diversion apertures (7) through piston (5) bottom, piston (5) is risen rapidly, open main valve; When spool (1) descends, because rubber seal (6) is close to clutch release slave cylinder and pistion recess top, has sealed piston and gap, clutch release slave cylinder place, the water in the clutch release slave cylinder is forced to flow out through throttling pore (8), spool (1) slowly descends, and has realized unidirectional, throttling buffer function.

Using scope of the present utility model is not limited to the pond water system of building, also can be used on other water supply occasions, and particularly using on glass container, pottery container, plastic article has its special superior part.
