Description

The mechanical type water level controller

The utility model relates to tank switch, specifically a kind of automatic controller for water level of fully mechanical.

Because the singularity of solar water heater, the used water supply regulator of existing various water tank can not be suitable for, therefore, in prior solar water heater, the water supply governor motion of its water tank normally utilizes a run-down pipe that is installed on water tank upper end whether to determine in the water tank topped up with water.During use, if find that run-down pipe has begun flowing water, then represent water tank full water, operating personnel close feed cock.The defective of this structure is a troublesome poeration, must have the people to note whether filling it up with constantly.Secondly, cause waste, caused waste when treating to begin flowing water in the run-down pipe, if things go on like this, wasting phenomenon is quite serious.

The purpose of this utility model is the formula water level controller that designs a mechanism, with handled easily, and the conserve water resource.

Its main technical schemes is that controller is by valve body, valve gap, spool and buoyancy aid and valve body constitute, at the inline tape splicing of the lumen of valve body the radially valve seat of manhole appendix is arranged, the bottom of this valve seat is communicated with import and export, the top of valve body connects valve gap, the valve rod that can move up and down is arranged in the inner chamber of valve gap, the lower end of this valve rod connects the spool that has O-ring seal, valve rod stretches out valve gap, connect block in the top, on the valve rod between valve gap and block, be with the buoyancy aid that can move up and down, back-moving spring is arranged on valve rod, and the external diameter of spool and O-ring seal has endoporus greater than the external diameter of valve gap inner chamber on the wall of valve gap.Back-moving spring is enclosed within outside the upper surface and the valve rod between the spool end of inner chamber, the guide rod that on valve gap, connects hollow, the part that valve rod stretches out valve gap is positioned at guide rod, buoyancy aid should be positioned at outside the guide rod, upper end at guide rod connects the top cap, back-moving spring is between top cap and block, ring flange is arranged at the top of endoporus on valve gap, valve body utilizes its extension to connect with ring flange, and form epicoele betwixt, hole outside having on the wall of extension, having in the contact position of valve body and valve gap can be with exocoel and the isolated O-ring seal of lumen.

The utility model has the advantages that easy to use, when water inlet, buoyancy aid raises with the rising of liquid level, and buoyancy aid is run into block when rising to certain position, and drive block and move on together, valve rod and spool move simultaneously, to the tight valve gap of O-ring seal card bottom, close till the inlet port of inner chamber, automatic closing function with water tank water intake, compare with the mode of utilizing the run-down pipe operation originally, both convenient, do not waste water again.During hot water in needs utilize water tank, close the feed cock of cold water, open cock of water drain, this fluid level controller is in time opened spool when liquid level descends, make hot water along outer hole, epicoele endoporus, inner chamber be through lumen, manhole appendix, import and export discharge.

Fig. 1 is a structural drawing of the present utility model.

The installation side cornice has the radially valve seat 13 of manhole appendix 11 in the lumen 15 of valve body 10 inside, it on valve seat 13 loam cake 19, the bottom is the opening that is communicated with the import and export 12 of valve body 10 lower ends, water is through importing and exporting 12 when entering, arrive in the lumen of valve body along manhole appendix 11, thereby avoided the direct impact of current spool.Spool 17 is positioned at the valve seat top of lumen 15, connects O-ring seal 14 on spool 17, and the top of spool can be stretched in the inner chamber 18 of valve gap 7, connects valve rod 4 on spool top, and this valve rod 4 stretches out valve gap 7.

Valve gap 7 utilizes the ring flange 21 at its middle part to connect with the extension 22 on valve body 10 tops, the chassis of valve gap 7 contacts with valve body, in its contact position O-ring seal 9 is set, ring flange 21 at valve gap 7,22 of the extensions of chassis and sidewall thereof and valve body 10 form epicoele 16, on the valve gap wall of 18 of epicoele 16 and inner chambers, endoporus 6 is arranged, hole 8 outside on the sidewall of the extension 22 of valve body 10, having, the bottom of spool 17 is bigger than the bottom external diameter of valve gap inner chamber 18 with the external diameter of its O-ring seal 14, so that when spool moves to certain position on valve, can tightly be posted on the chassis of valve gap, close water stream channel, outside the valve rod of the upper surface of valve gap inner chamber 18 and valve core chamber, be with the back-moving spring 20 that can make valve core reset.

The part of stretching out valve gap at the upper end of valve gap 7 connection guide rod 3, valve rod is positioned at guide rod, and can be upper and lower within it move, being with outside guide rod can upper and lower mobile buoyancy aid 5, at the top of guide rod crown cap 1, on the guide rod below the cap of top, rectangular through holes is arranged, the block 2 that is connected on the valve rod 4 stretches out this through hole, and this block can contact with buoyancy aid when buoyancy aid rises, and rises under buoyancy aid drives thereupon, drive valve rod, spool rises, and tightly is posted on the valve gap bottom to O-ring seal 10, till the valve-off.
