The model utility content
To the problems referred to above, the utility model proposes a kind of reasonable in design, can directly insert the reducing filter check valve between the different-diameter pipe fitting.
For solving this technical problem, the utility model is taked following scheme: a kind of reducing filter check valve comprises valve body, valve gap, flap and valve rod; Said valve body is provided with feed-water end and the waterexit end that is connected with pipe fitting vertically, and said feed-water end is provided with internal thread or the outside thread that is connected with pipe fitting with the waterexit end, and the adjacent place of the friendship of said valve body between feed-water end and waterexit end is provided with valve seat; Have valve port on the said valve seat; Said valve gap is located at the valve seat top of valve body, but on the valve port of being located at valve seat of said flap folding, said bonnet lower is provided with guide holder; One end of said valve rod is telescopic to be located in the guide holder of valve gap; The other end is fixedly connected with flap, and the place ahead that said valve body is positioned at valve port also is provided with cartridge filter, and the external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality.
Further improvedly be: the bottom that said valve body is positioned at the valve seat valve port is outward extended with the cartridge filter oblique chamber of perforation into and out of water end (W.E.); Said cartridge filter is removable to be installed in the oblique chamber of cartridge filter, also removablely on the free end in the oblique chamber of said cartridge filter is provided with obstruction.
Further improvedly be: also comprise spring, said spring housing is located on the periphery of said guide holder in the valve body, and the one of which end resists on valve gap, and the other end resists on flap.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: this novel reducing filter check valve, and the external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality, have solved the problem that directly inserts filter check valve between the different-diameter pipe fitting; Convenient installation and operation; Save the consumption and the construction operation amount of pipe fittings, reduced the junction point of pipeline, the bonding point of having reduced dielectric leakage.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 1, present embodiment discloses a kind of reducing filter check valve, comprises valve body 1, valve gap 2, flap 3, valve rod 4 and cartridge filter 5; Said valve body 1 is provided with feed-water end 11 and waterexit end 12 vertically; Said feed-water end is provided with internal thread or the outside thread that is connected with pipe fitting with the waterexit end, and said valve body 1 is provided with valve seat 13 between feed-water end 11 and waterexit end 12, has the valve port 131 that connects feed-water end 11 and waterexit end 12 on the said valve seat 13; Said valve gap 2 is located at the top of valve body 1 the above valve seat 13; But on the valve port of being located at valve seat 13 131 of said flap 3 through the pressure folding of medium fluid, said valve gap 2 bottoms are provided with guide holder 21, and an end of said valve rod 4 is telescopic to be located in the guide holder 21 of valve gap 2; The other end is fixedly connected with flap 3; The bottom that said valve body 1 is positioned at valve seat 13 valve ports 131 is outward extended with the cartridge filter oblique chamber 14 of perforation into and out of water end (W.E.), said cartridge filter 5 removable being installed in the oblique chamber 14 of cartridge filter, and cartridge filter can Direct Filtration fall the impurity in the water; Solved and had impurity in the water; Influence the technical barrier of hot-water heating facility proper functioning, also removable being provided with stops up 6 on the free end in said cartridge filter 5 oblique chambeies, stops up to make cartridge filter dismounting convenience for washing; This novel filter check valve, its cartridge filter is directly installed in the valve body, and is simple in structure, cost is low; Need not to install respectively, reduced the junction point of pipeline, reduced the installation and the maintenance cost of drainage system; Installation, maintenance is convenient, and is time saving and energy saving, brings convenience to the workmen; Said valve inleting water end 11 is all inequality with the external diameter and the internal diameter of waterexit end 12, this novel reducing filter check valve, and the external diameter and the internal diameter of said valve inleting water end and waterexit end are all inequality; Solved the problem that directly inserts filter check valve between the different-diameter pipe fitting, convenient installation and operation, the consumption and the construction operation amount of having saved pipe fittings; Reduce the junction point of pipeline, reduced the bonding point of dielectric leakage.
Also comprise spring 7, said spring 7 is sheathed on the periphery of said guide holder 21 in the valve body 1, and the one of which end resists on valve gap 2, and the other end resists on flap 3.When the pressure of feed-water end in the valve body during greater than the pressure of waterexit end, pressure medium can be washed pressure that flap overcomes spring open and valve rod moved upward pass through smoothly, and spring can be alleviated the instantaneous pressure of feed-water end; Play a part to regulate current, have energy-conservation effect, when the flow of fluid changes; The pressure of the telescopic variation available buffer fluid of spring makes media flow constant, has quiet effect; When waterexit end pressure during greater than feed-water end pressure, compressed spring return, the elastic force of spring return and the pressure of adverse current act on flap simultaneously; Make fast downwards throttle down of flap, prevent the water hammer and the pneumatic hammer that produce because of adverse current, can protect the safety of pipe-line system; Prolong the working life of valve body, the pressure of waterexit end hour in valve body can not produce leakage phenomenon yet.
The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
