Abstract
The utility model discloses a water flow check valve which comprises a valve body (1). A channel (2) is formed in the valve body (1); a valve hole (3) and a valve rod (4) capable of moving axially are arranged in the channel (2); a valve plate (5) capable of blocking the valve hole (3) is arranged on the valve rod (4); and a spring (6) which is propped on the valve body (1) to enable the valve plate (5) to be sealed on the valve hole (3) is arranged on the valve rod (4). The valve body, the valve rod and the valve plate all can be made through injection molding, the production is convenient and the cost is low. The unidirectional pressure adopts the design of spring so as to ensure the product can be mounted at any angle; the low water-pressure unidirectional performance is good; and low water-pressure reverse sealing property is ensured by adopting a seal ring to seal.
Description
Technical field
The utility model relates to a kind of current one-way valve for the use of wall hanging furnace interior.
Background technique
At present, need use the current one-way valve to come the unidirectional conducting of controlled water flow at the wall hanging furnace interior.Traditional current one-way valve generally uses metallic material to make on the market, and its volume is big, cost is high, the unidirectional conducting weak effect of its current under this external low hydraulic condition, and must vertically install and could normally use.Owing to have above shortcoming, use so can't be applicable to the wall hanging furnace interior.
The model utility content
The purpose of this utility model is to provide that a kind of volume that is applicable to the wall hanging stove is little, cost is low, convenient for production, low hydraulic pressure one-way performance is good, capable of arbitrary angle mounting current one-way valve.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the current one-way valve, comprise valve body, be provided with passage in the described valve body, be provided with valve opening and can axially movable valve rod in the passage, valve rod is provided with the valve block that can seal valve opening, and valve rod is provided with the top and is located at and makes valve block be sealed in spring on the valve opening on the valve body.
Described valve block is provided with seal ring.
Described valve block is provided with circular groove, and seal ring is provided with in the circular groove.
In the utility model when work,, when the pressure that imposes on valve block at water inlet one side canal of valve opening imposed on the pressure sum of valve block greater than spring force and water outlet one side canal, spring was compressed, and valve block leaves valve opening, one-way valve opens.When if the pressure that imposes on valve block at water inlet one side canal of valve opening imposes on the pressure sum of valve block less than spring force and water outlet one side canal, the spring elongation, valve block is sealed on the valve opening, closed check valve.Valve body of the present utility model, valve rod and valve block all can be injection molded, convenient for production, cost is low, and uniaxial pressure adopts the spring design to guarantee that this product can be suitable for arbitrarily angled installation, low hydraulic pressure one-way performance is good, adopts the seal ring sealing to guarantee the low reverse sealing of hydraulic pressure.The utility model is simple in structure, has very strong practicability and promotional value, can be widely used in the wall hanging furnace interior and use.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the sectional view of current one-way valve.
Embodiment
As shown in Figure 1, current one-way valve described in the utility model comprises valve body 1, is provided with passage 2 in the described valve body 1, is provided with valve opening 3 and can axially movable valve rod 4 in the passage 2, and valve rod 4 is provided with the valve block 5 that can seal valve opening 3.Valve body 1, valve rod 4 and valve block 5 all can be injection molded, and uniformity convenient for production is good.Valve rod 4 is provided with the top and is located at and makes valve block 5 be sealed in spring 6 on the valve opening 3 on the valve body 1.Described valve block 5 is provided with seal ring 7.The set-up mode of seal ring 7 is that circular groove 8 is set on valve block 5, and seal ring 7 is provided with in the circular groove 8, adopts seal ring 7 sealings can guarantee the low reverse sealing of hydraulic pressure.
Working principle of the present utility model: when the pressure that imposes on valve block 5 at water inlet one side canal 2 of valve opening 3 imposed on the pressure sum of valve block 5 greater than spring 6 elastic force and water outlet one side canal 2, spring 6 was compressed, and valve block 5 leaves valve opening 3, one-way valve opens.When if the pressure that imposes on valve block 5 at water inlet one side canal 2 of valve opening 3 imposes on the pressure sum of valve block 5 less than spring 6 elastic force and water outlet one side canal 2, spring 6 elongations, valve block 5 is sealed on the valve opening 3, closed check valve.
The utility model is when concrete the application, and it can be used as the dedicated devices of effectively isolating water supply pipe and heating pipe in the wall hanging furnace system.When wall hanging stove user opens priming valve, tap water can unidirectional adding heating pipe.When heating pipe hydraulic pressure was higher than tap water hydraulic, one-way valve can be closed automatically and be added water channel, prevented that the aqueous reflux in the heating pipe from entering water supply pipe, rang the hygienic quality of shadow tap water, stopped to exist in the system possibility of polluting tap water.The utility model also can be serially connected between the water outlet and water return pipeline of wall hanging stove heating, can prevent to cause because of line clogging the heat exchanger overheated security incident that occurs of moment of wall hanging furnace interior, effectively protection device.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
