Abstract
The utility model discloses a vacuum suppressor used in water supply system, which can prohibit water supply system from generating negative pressure therein and maintain the balance of pressure on the service pipe net. The utility model includes a suppressor tube and a floating ball positioned inside the suppressor tube cavity and connected with a valve plug by a guide rod. The valve plug is flexibly sheathed inside the valve body through-hole and the valve body is connected with a valve seat, which is fixedly arranged on the upper end of the suppressor tube by a ring flange with air tightness. The valve seat and the valve body are respectively provided with through-holes that are communicated with each other. A gland bush is arranged between the valve seat and the valve body.
Description
Technical field
The utility model relates to a kind of water supply installation, relates in particular to a kind of vacuum suppresser that is used for water system.
Background technology
In the city tap-water pipe network, if water supply installation directly connects with the tap water pipe network,, destroy the pressure balance of tap water pipe network because water pump suction produces negative pressure easily in pipe network, impact for certain customers' water.For this phenomenon, the solution that existing water system is all desirable without comparison.
Utility model content the purpose of this utility model is the problem that exists at prior art, and a kind of vacuum suppresser that is used for water system is provided.It can make water supply installation suppress to produce negative pressure in the pipe network when directly connecting with the tap water pipe network, keeps the pressure balance of tap water pipe network.
The technical solution of the utility model comprises the inhibition tube, place the ball float that suppresses tube inner chamber, described ball float is connected on the spool through guide rod, described spool is movably set on the valve body, described valve body is connected on the valve seat, described valve seat is fixedly arranged on described inhibition tube upper end through the flange tightness, and described valve seat and valve body are respectively equipped with the gas passage of mutual UNICOM, are provided with sealing mat between described spool and the valve seat.
Described valve seat and valve body are respectively equipped with through hole, and described gas passage is made of set perforate on this two through hole and the described body wall, and described spool is movably set in the described valve hole.
Described valve body is provided with the waist-shaped hole that radially connects, and described spool is by bearing pin set installing hole and valve body flexible connection on this waist-shaped hole and spool; Described inhibition tube top is provided with protective cover.
Described sealing mat is fixedly arranged on the upper surface of spool.
The utility model utilize the upper and lower motion of ball float to water system inflate, exhaust and sealing, thereby reach the inhibition vacuum, keep the pressure balanced purpose of tap water pipe network; Particularly when the exhaust of controlling water system according to operating mode automatically or air inlet, it is active in one's movements, and simple in structure.
Description of drawings
Fig. 1 is the utility model theory structure schematic diagram.
The specific embodiment
As shown in Figure 1, flange 10 is fixedly connected on the upper end that suppresses tube 9 through the bolt tightness; Ball float 1 places and suppresses tube 9 inner chambers and be fixed in spool 3 lower ends through guide rod 2.Valve seat 8 places in the inhibition tube 9 and tightness inversion is installed on the flange 10, and valve body 7 is installed in the lower end of valve seat 8.By the through holes 14 of two valve seats 8 that mutually axially connect and the through hole 13 of valve body 7, and set perforate 12 constitutes the gas passage of UNICOMs in atmosphere and described inhibition tube 15 inner cavity chamber on valve body 7 sidewalls.Respectively be provided with a waist-shaped hole on the two lateral walls of valve body 7 respectively, spool 3 is movably connected in the through hole 13 on the valve body 7 by the installing hole on this two waist-shaped hole 11 and the spool 3 by bearing pin 4, these through hole 13 its underparts and spool 3 are matched in clearance, to play the guide effect that spool 3 moves up and down.Sealing mat 6 is fixedly arranged on the upper surface of spool 3, and can form sealing with the lower surface of valve seat 8.
Suppress tube 9 lower ends through the bolt tightness be fixed in water system flow straightener (cistern) 15 and with its formation UNICOM.Flow straightener 15 is respectively equipped with water inlet and delivery port.When inflow causes drawdown less than water yield in the flow straightener 15, ball float 1 drives spool 3 toward falling by guide rod 2, the through hole 13 of flow straightener 15 inner cavity chamber this moment on valve body 7 side-wall holes 12, valve body 7, the through hole 14 of valve seat 8 communicate with atmosphere, at this moment by atmosphere to flow straightener 15 tonifying Qi; Otherwise, when liquid level in the flow straightener 15 rises, ball float 1 drives spool 3 by guide rod 2 and rises, at this moment, by above-mentioned same path is flow straightener 15 exhausts, until spool 3 upper surfaces near valve seat 8 lower surfaces, thereby drain air in the flow straightener 15, and form sealing by 6 pairs of flow straighteners of sealing mat 15.The upper limit of the upstroke of spool 3 is spacing by valve seat 8 lower surfaces, and the lower limit of its downward movement is spacing by waist-shaped hole 11.
But inhibition tube 9 tops are provided with shield plate 5 dust protection fouls and fall in the flow straightener.
The suitable especially water system of using little volume flow straightener of the utility model.
