Description
Technical field
The utility model relates to a kind of reduction valve, and is especially relevant with water pressure reducing valve.
Background technique
Existing water pressure reducing valve is owing to be connected so that screw is sealed between valve body and the pressure regulating cover, and the influence of not considering current impurity, it is bigger to exist the reduction valve volume, cost of production is higher, easily cause deficiencies such as influencing current effect of easing stress and damage water pressure reducing valve in the current impurity ingoing stream reduction valve, in addition, it all is the sealing strip sealing that existing water pressure reducing valve is connected with pipeline thread, cause valve body cracking or poor sealing too deeply owing to being screwed into when easily causing pipeline to be screwed into, and, also exist deficiencies such as designing unreasonable and sealing effect difference because inner counter adopts plane sealing to sealing.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, connects reliably, and is easy for installation, the working environment cleaning, and long service life, effect of easing stress reaches the low water pressure reducing valve of cost of production well.
For achieving the above object, the utility model is achieved through the following technical solutions.Water pressure reducing valve comprises valve body, valve core rod, pressure regulating cover, epithelium, spring, spring seat, screw press, nut, epithelium compressing tablet, valve core rod O type circle, O type circle before the O type circle behind the Pressure relief valve seat, Pressure relief valve seat, Pressure relief valve seat, gasket seal, sealing gasket compressing tablet, hexagonal nuts, catch and return port, the outside thread of establishing on the valve body on internal thread and the pressure regulating cover is connected.
Described water pressure reducing valve also comprises filter screen, and filter screen is located at the Pressure relief valve seat circumferential surface, and behind Pressure relief valve seat before O type circle and the Pressure relief valve seat between the O type circle.
Described water pressure reducing valve, its return port is not communicated with water intake misorientation setting on the Pressure relief valve seat, and return port is 1-8.
Described water pressure reducing valve is provided with groove and protruding circle at Pressure relief valve seat one end, and groove is communicated with return port.
Described water pressure reducing valve, water intake on its valve body and water outlet are all the Internal Pipe Thread structure, are respectively equipped with flat gasket in its mouthful.
The utility model compared with prior art has the following advantages: (one) is owing to adopt the outside thread of establishing on internal thread and the pressure regulating cover on the valve body to be connected, water intake and water outlet are all the Internal Pipe Thread mode of structure, be respectively equipped with plain cushion in its mouthful, change traditional sealing strip and be sealed into the sealing of end face plain cushion, make the water pressure reducing valve structure more become reasonable, connect reliably, easy for installation, beautiful shape; (2) be owing to adopt filter structure, overcome deficiency, guaranteed the cleaning of working environment, improved effect of easing stress, prolonged working life because of causing inner chamber to pollute, stop up and damage water pressure reducing valve in the impurity ingoing stream reduction valve; (3) also be provided with protruding circle on Pressure relief valve seat, having changed traditional plane sealing structure is the linear sealing structure, has improved sealing effect, has increased pressure stability.
