Abstract
The utility model relates to the field of valves, in particular to a pressure-reducing valve. The technical scheme of the pressure-reducing valve includes a valve body, a valve rod, an upper valve cover and an assistant valve body, wherein the upper valve cover is fixedly connected with the upper portion of the valve body, and the assistant valve body is connected with the upper valve cover. A fluid outlet and a fluid inlet are formed in the valve body. A main valve seat is arranged on the valve body. A fluid channel which can be used for communicating the fluid inlet and the fluid outlet is also arranged on the main valve seat. The valve rod is installed in the fluid channel in a communicated mode. A main valve is arranged on the valve rod. The main valve is arranged on the lower portion of the main valve seat. A resetting mechanism is sleeved at the lower end of the valve rod. The middle-upper portion of the valve rod is placed in the assistant valve body. A regulating spring is sleeved on the outer wall of the middle-upper portion of the valve rod. The upper end of the regulating spring is contacted with the assistant valve body, and the lower end of the regulating spring is contacted with the upper valve cover. The pressure-reducing valve has the advantages that a start-close way of a film slice is changed; the form of the main valve is used for greatly prolonging the service life of the pressure-reducing valve, so that the pressure-reducing valve is simple in structure and easy to achieve; and the resetting mechanism and the regulating spring can be installed, so that opening-closing positions of the main valve are effectively adjusted.
Description
Technical field
The utility model relates to valve field, refers to especially a kind of reduction valve.
Background technique
Reduction valve can apply to the industries such as oil, metallurgy, food, textile printing and dyeing and medicine, and its Main Function is to keep constant for the pressure with pipe outlet.At present, the structure of relief pressure valve that occurs on market and data is comparatively complicated, and cost of production is higher, and spool adopts diaphragm more, and the working life of diaphragm is shorter, changes inconveniently, and easily occurs leaking, and can't guarantee.
The model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simple in structure and stable reduction valve.
the technical solution of the utility model is achieved in that a kind of reduction valve, comprise valve body, valve rod, be fixedly connected on the bonnet on valve body top and be connected in the valve body of paying of bonnet, be provided with fluid output and fluid input on described valve body, and also be provided with main valve seat on valve body, also be provided with the runner of conducting fluid input and fluid output on this main valve seat, described valve rod wears this runner setting, be provided with main valve on described valve rod, this main valve is arranged at the bottom of main valve seat, described valve rod lower end is arranged with resetting-mechanism, described valve rod upper position is in paying valve body, and the outer wall of valve rod middle and upper part is arranged with Regulation spring, the upper end of this Regulation spring contacts with a pair valve body, the lower end contacts with bonnet.
By adopting technique scheme, changed the opening/shutting mode of diaphragm, adopt the form of main valve, greatly improved the working life of reduction valve, such is simple in structure, is easy to realize, and resetting-mechanism and Regulation spring are set, have effectively realized regulating the position that main valve is opened.
The utility model further is set to: described resetting-mechanism is Returnning spring, and the upper end of this Returnning spring is fixedly connected with main valve, and the lower end of Returnning spring is connected with valve body; Described valve body comprises valve body body and bottom valve, and described valve body body bottom is provided with through hole, and the axial outside of this through hole is fixedly connected with bottom valve; Be provided with bleeder port on described bonnet; Described valve body body adopts screw to be connected with bottom valve.
By adopting technique scheme, adopt Returnning spring to reset, effectively utilize the elastic force of self to assist resetting of main valve, and bottom valve is set, when need are changed Returnning spring, only need pull down bottom valve, change Returnning spring, easy to operate, and simple in structure; The bleeder port that arranges at last, effectively the normal operation of assisted decompression valve is carried out.。
