Description

Be used to water feed apparatus with the water tank sanitaryware

Technical field

The utility model relates to a kind of water feed apparatus that is used to the water tank sanitaryware.

Background technology

In the prior art, adopt the intelligent closestool or the geyser of water tank type heating technique, for guaranteeing the safety of water tank, usually in the water inlet loop of water tank, add electromagnetic relief pressure valve, guaranteed that like this water tank uses under certain safe pressure, though described prior art is provided with electromagnetic relief pressure valve, its security performance is still not enough, design unreasonablely, and do not possess check function.And the electromagnetic valve of most of product is positioned at the reducing valve prime, and water under high pressure can produce the switch of electromagnetic valve and destroy like this, influences application life; In addition, most of product does not have the pressure release function yet, is to be provided with on the level water tank of back even have yet, and causes the complicated of cisten mechanism like this, and the adaptation of product is not strong.Described defective value must improve.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned prior art; a kind of water feed apparatus that is used to the water tank sanitaryware is provided; forming with one way valve, reducing valve, electromagnetic valve, relief valve in the water inlet loop is the pile-up valve of one; realize defencive function, improve the product safety coefficient and the adaptation of product water tank.

The technical scheme taked of the utility model is to achieve these goals: a kind of water feed apparatus that is used to the water tank sanitaryware, and unidirectional valve gap is compacted to one way valve gum cover, nonreturn valve core and one-way valve spring in the water supply connector, forms an one way valve; The reducing valve plug compresses the lower end of relief pressure valve cartridge to valve seat, the reducing valve regulating block be threaded to decompression compress in the valve gap relief spring, nut, decompression film fixing last slice, decompression film, fixing sheet to the valve seat and relief pressure valve cartridge down of decompression film be connected to form a reducing valve, the degree of depth that the reducing valve regulating block screws in the decompression valve gap can change the precompression of relief spring, thereby changes the size of reducing valve output pressure value; Screw is fixed in electromagnetic coil, electromagnetic valve core retainer plate, electromagnetic valve spring, electromagnetic valve core, electromagnetic valve diaphragm lid, electromagnetic valve diaphragm valve seat and forms an electromagnetic switch valve; Screw is fixed in pressure release valve gap, pressure release spring, pressure releasing valve core, relief valve gum cover and forms a relief valve on the valve seat.

Because adopt said structure, one way valve, reducing valve, relief valve all rely on the spring in the valve body to realize the function of each valve body, the precompressed value of the spring in the valve body is the power value of valve event; Hydraulic pressure is pushed the respective springs in the valve body open after hydraulic pressure reaches each design load, realize the effect of respective valves, so the utility model has been simplified the structure of back level water tank, improved the safety factor of water tank, improved the defective that the water tank retaining refluxes, promote the practicality and the reliability of product, improved the product safety coefficient and the adaptation of product, convenient and practical.

The specific embodiment

As shown in Figure 1, 2, a kind of water feed apparatus that is used to the water tank sanitaryware, unidirectional valve gap 12 is compacted to one way valve gum cover 13, nonreturn valve core 14 and one-way valve spring 15 in the water supply connector 28, forms an one way valve; Reducing valve plug 10 compresses the lower end of relief pressure valve cartridge 11 to valve seat 1, reducing valve regulating block 8 be threaded to decompression compress in the valve gap 7 relief spring 6, nut 5, decompression film fixing last slice 4, decompression film 3, the fixing sheet 2 down of decompression film to valve seat 1 and relief pressure valve cartridge 11 be connected to form a reducing valve, the degree of depth that reducing valve regulating block 8 screws in decompression valve gap 7 can change the precompression of relief spring 6, thereby changes the size of reducing valve output pressure value; Screw 9 is fixed in valve seat 1 with electromagnetic coil 25, electromagnetic valve core retainer plate 24, electromagnetic valve spring 23, electromagnetic valve core 22, electromagnetic valve diaphragm lid 21, electromagnetic valve diaphragm 20 and forms an electromagnetic switch valve; Screw is fixed in pressure release valve gap 16, pressure release spring 17, pressure releasing valve core 18, relief valve gum cover 19 and forms a relief valve on the valve seat 1.

Operating principle of the present utility model is: 1, external tap water enters in the hole of unidirectional valve gap 12, self pressure by tap water backs down one-way valve spring 15, the slit of water between nonreturn valve core 14 and water supply connector 28 flows in the valve seat 1, when the pressure of faucet 9 during greater than the pressure of water supply connector 28, the pressure reduction of water all acts on the nonreturn valve core 14, nonreturn valve core 14 is compressed on the one way valve gum cover 13, thereby play sealing function, stop the backflow of water.2, the pressure that enters the water of valve seat 1 all acts on the relief pressure valve cartridge 11, relief pressure valve cartridge 11 promotes relief spring 6 under the effect of hydraulic pressure, relief spring 6 realizes that according to reducing valve regulating block 8 formed precompressions the water of its relevant pressure size passes through, thereby reaches the purpose of decompression.3, through post-decompression water realized to after the level (electromagnetic valve) protection; rubber stopper under the normality on the electromagnetic valve core 22 of electromagnetic valve under the effect of electromagnetic valve spring 23 is sealing up the inlet opening on the electromagnetic valve diaphragm lid 21; when leading to the voltage of going up DC12V to power supply terminal on the valve body 26; electromagnetic coil 25 is under electromagnetic action; electromagnetic valve core 22 is inhaled to be opened; thereby open the inlet opening of electromagnetic valve diaphragm lid 21, realize the function of valve switch.4, when the prime reducing valve lost efficacy; the water of high pressure can produce electromagnetic valve and destroy; cause the phenomenon that electromagnetic valve can't normal switch; this moment, the relief valve in parallel with electromagnetic valve can play a protective role, and was embodied as: when water under high pressure surpassed the precompressed value of pressure release spring 17, hydraulic pressure compressed it; pressure releasing valve core 18 is separated with relief valve gum cover 19; the water under high pressure pressure release valve gap 16 of from the dentation slit of pressure releasing valve core 18, flowing through, external by pressure release valve nozzle 29 blow off valves, realize the pressure release function.
