Description
Technical field
The utility model relates to water heater and uses thermostatic valve, specifically, relates to a kind of antifreeze constant temp valve.
Background technique
Thermostatic valve is widely used in electric water heater, solar water heater etc.; After thermostatic valve was installed, the user can regulate hot and cold water water-mixing temperature, temperature required can reaching rapidly and settle out as required voluntarily; Guarantee effluent temperature constancy, and do not receive the influence of water temperature, flow, variation in water pressure.The drawback that traditional thermostatic valve has is: do not have antifreeze function, owing to after people use up hot water, all can have unnecessary water to stay in the constant temperature valve body at every turn; When wintry weather was cold, the water that remains in the constant temperature valve body will freeze, and is easy to the constant temperature valve body is damaged; When reusing water heater, need change thermostatic valve again, make troubles not only can for people's life; And, also to increase extra cost.
In order to solve the antifreeze problem of thermostatic valve; People improve traditional thermostatic valve; Like the patent No. is 201020187630.1; Name is called the utility model patent of " a kind of mixed water valve that has the dewatering outlet ", and the technological scheme of this patent is to be provided with the dewatering outlet in the bottom of valve body, and at the place, dewatering outlet the screw that discharges water is set.At ordinary times, with the screw shutoff dewatering outlet that discharges water, winter, use up hot water after, back out the screw that discharges water, residual water is discharged through the dewatering outlet in the valve body, has solved residuary waters in the valve body in winter and has frozen and damage the problem of valve body.But the technological scheme of above-mentioned patent still has certain defective: the screw that 1, discharges water is not easy to screw down, must be by instruments such as screw-drivers; 2, be arranged between cooling water inlet and the hot water inlet owing to the dewatering outlet; And the space between them is very little, and hand-operated tools such as screw-driver are difficult to put in backs out the screw that discharges water, and the screw that discharges water twists not get off; The water row who remains in the valve body does not come out, and loses antifreeze function; 3, the dewatering outlet is too little, and the speed that discharges water is slow, weak effect; 4, the function that does not possess water filling in the water storage box of water heater.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective, a kind of draining convenience, good effect of freezing protection is provided, possesses the antifreeze constant temp valve of water-filling function in the water storage box of water heater.
A kind of antifreeze constant temp valve; Comprise valve body, be located at cooling water inlet, the hot water inlet of valve body bottom and be located at the mixed water out at valve body top that be provided with the dewatering outlet between cooling water inlet and the hot water inlet, the place, dewatering outlet is provided with the screw that discharges water; It is characterized in that: the inner hollow of the said screw that discharges water; Its top closure, bottom opening, sidewall are provided with at least one permeable hole; The projection periphery, screw top that discharges water is with seal ring.
A kind of improvement as technique scheme is provided with fixed base in the said valve body, and the dewatering outlet is located at the top of fixed base; The screw thread that discharges water is connected in the fixed base, and the external diameter of its top projection is more than or equal to the diameter of dewatering outlet, and through this projection and the seal ring sealing dewatering outlet that is enclosed within on the projection.
Another kind as technique scheme improves, and said dewatering outlet is located on the shell wall of valve body bottom, and its periphery is provided with fixed base, is provided with the turnbuckle that discharges water in the fixed base, and the turnbuckle top that discharges water is provided with through hole; The outer wall of turnbuckle of discharging water is connected with the inner thread of fixed base, and inwall is connected with the screw thread that discharges water; Discharge water the external diameter of screw top projection more than or equal to the diameter of the through hole at the turnbuckle top that discharges water, through this projection and the seal ring sealing through hole that is enclosed within on the projection.
Say further:
The above-mentioned last water frame that is " worker " font that also comprises, last water frame comprises the water service pipe of cold water pipe, hot-water line, connection cold water pipe and hot-water line, and ceramic quick opening valve is installed on the cold water pipe; Water service pipe and ceramic quick opening valve are symmetricly set on the inside and outside both sides of cold water pipe; The water outlet of cold water pipe connects the cooling water inlet of valve body, and the water outlet of hot-water line connects the hot water inlet of valve body.
The said periphery that discharges water the screw lower end is provided with antislip ring.
Owing to adopted technique scheme, compared with prior art, the screw that discharges water of the utility model can be turned on the have gentle hands loose ground, need not just can the water that remain in the valve body be emitted by other instruments, and the speed that discharges water is fast, good effect of freezing protection; In addition, the utility model is provided with water frame on " worker " font, through water frame on this, and directly water filling in the water storage box of water heater.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
