Abstract
The utility model belongs to a fitting of a solar water heater, particularly a water supply valve for a solar water heater. The utility model comprises a valve body 6, a valve core sleeve 7 and a valve core 8, wherein the other end of the valve body 6 is provided with a pressure relief valve core sleeve 1, and a pressure relief valve core 3 and a water stop wall 4 are arranged in the valve body 6 at the pressure relief valve core sleeve 1; the water stop wall 4 is fixed on the inner wall of the valve body 6, the valve core 8 carry out guide through a guide hole 10 arranged in the valve core sleeve 7, the pressure relief valve core sleeve 1 and the valve body 6 are in threaded connection, the center of the pressure relief valve core 3 is provided with a water injecting hole 12 and the circumference of the pressure relief valve core 3 is provided with flow guide blades 2. The utility model has the advantages of simple structure, convenient operation, high safety and low cost; moreover, the water supply can be carried out as well as the water supply can be automatically sealed when water pressure is overlarge.
Description
Technical field
The utility model belongs to the solar water heater accessory, especially for the water supply valve of solar water heater.
Background technique
Solar water heater is subjected to users' welcome owing to energy-conservation very much.But owing to have a lot of problems in the last water, bad grasp during toward water has up been forgotten to close Cold water tap, and the water in the water tank is overflowed, and causes and wastes water, and brings many inconvenience for the user of bottom.Solar water heater has generally adopted the ball float water supply valve at present, this water supply valve can only play the effect of water in the automatic sealing, but because unreasonable structure, so in the big area of hydraulic pressure, because hydraulic pressure too greatly at all can't proper functioning, make that solar water heater is anhydrous can be gone up, reduction valve can only be installed on pipeline, just can play the effect of water.Installation both bothered like this, had increased material cost again, had frequently increased the after service cost of producer owing to maintenance.
Summary of the invention
The purpose of this utility model is design at the problem of above existence a kind of simple in structure, can go up esy to use, safe and reliable, low-cost a kind of water-supply valve of solar water heater that water can seal water again automatically when hydraulic pressure is big.
The utility model is achieved in that it is at original valve body, valve core housing and spool of including, they are respectively with the order suit, the other end of the valve body of ball float water supply valve is provided with the reduction valve core retainer plate, be provided with relief pressure valve cartridge and the wall that blocks water in the valve body of reduction valve core retainer plate end, the wall that blocks water is fixed on the valve interior wall.The spool of valve body one end is by being located at the pilot hole guiding in the valve core housing.The center of relief pressure valve cartridge is provided with water injection hole, is provided with guide vane on the border of relief pressure valve cartridge.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is that the A of the utility model relief pressure valve cartridge is to view.
Accompanying drawing 3 is a B-B cross section view of the present utility model.
Accompanying drawing 4 is a C-C sectional drawing of the present utility model.
Accompanying drawing 5 is another embodiment's of the utility model pilot hole a C-C sectional drawing.
Among the figure: 1-reduction valve core retainer plate, 2-guide vane, 3-relief pressure valve cartridge, 4-block water wall, 5-seal ring, 6-valve body, 7-valve core housing, 8-spool, 9-hole, 10-pilot hole, 11-valve core housing endoporus, 12-water injection hole, 13-gap.
Embodiment
The utility model is described in further detail in conjunction with the accompanying drawings.
The utility model includes valve body 6, valve core housing 7 and spool 8, they are respectively with the order suit, the other end at valve body 6 is provided with reduction valve core retainer plate 1, in the valve body 6 of reduction valve core retainer plate 1 end, be provided with the relief pressure valve cartridge 3 and the wall 4 that blocks water, the wall 4 that blocks water is fixed on valve body 6 inwalls, and the spool 8 of valve body 6 one ends is by being located at pilot hole 10 guiding in the valve core housing 7.Reduction valve core retainer plate 1 is threaded with valve body 6.The center of relief pressure valve cartridge 3 is provided with water injection hole 12, is provided with guide vane 2 on the border of relief pressure valve cartridge 3, and guide vane 2 is the 3-8 sheet.Pilot hole 10 also can be circular port for open (not sealing) square opening.
When using the utility model, need not to change the pipeline structure of protosun energy water heater, as long as the hole 9 of spool 8 ends is connected with pull bar on the ball float, an end valve core retainer plate 7 of this water supply valve is connected with casing, the other end reduction valve core retainer plate 1 is connected with water inlet and gets final product.When hydraulic pressure was too big, water was flushed on the wall 4 that blocks water and forms vaporific current from water injection hole 12, from the gap 13 between wall 4 and the valve body 6 of blocking water by flowing in the water tank of solar water heater in the endoporus 11 that enters valve core housing 7.When the water in the water tank arrives certain position, because the active force of ball float pulling pull bar and spool 8 make the flowing water passage closure of the valve core housing endoporus 11 of the other end of spool 8 and valve core housing 7, because the effect of seal ring 5 is not advanced in the water tank water, avoid in the water tank water superfluous and flow out, caused unnecessary waste.
The utility model is simple in structure, esy to use, safe and reliable, low price, can go up water when hydraulic pressure is too big, can seal a kind of water-supply valve of solar water heater of water again automatically.
