The utility model discloses a high-accuracy pressure regulating valve. The high-accuracy pressure regulating valve comprises a pedal (1), a spring (2), a valve seat (3), a valve rod (4), a valve element (5) and a valve body (6), wherein the valve element (5) is located in a cavity of the valve body (6) and can move in the axial direction of the valve body (6); the bottom of the valve rod (4) is vertically fixed to the top of the valve body (6) through a bolt, and the top of the valve rod (4) is connected with the valve seat (3); one end of the pedal (1) is movably connected to the top of the valve seat (3), the other end of the pedal (1) is suspended, and the spring (2) is further connected between the bottom of the pedal (1) and the valve seat (3). By means of the structure, the high-accuracy pressure regulating valve is convenient to install, flexible to operate, high in pressure regulating accuracy and stable and reliable in performance.
Description
Technical field
The utility model relates to pressure regulator valve field, is specifically related to highi degree of accuracy pressure regulator valve.
Background technique
The type of current valve and material are more and more, and the model establishment of valve is also more and more complicated.Though there is the unified standard of valve model establishment in China, more and more can not adapt to the needs of valve industry development.According to the effect difference of opening/shutting valve, valve sorting technique is a lot, but is mainly to classify by its role in pipeline.General valve in industry and civil engineering can be divided into 11 classes, i.e. gate valve, stop valve, stopcock, ball valve, butterfly valve, membrane valve, safety check, throttle valve, safety valve, reduction valve and drain valve.Pressure regulator valve is Lever type Pressure difference feedback control pressure regulation.Combustion gas in gas cylinder is liquid, and pressure is too high, must decompression just be applicable to burning.In petroleum machinery field, also need to use pressure regulator valve, and in petroleum machinery field, pressure regulation precision is had higher requirements, existing pressure regulator valve all can only carry out coarse adjustment pressure, installs complicated and be inconvenient to regulate, and cannot meet the needs of present use.
Model utility content
The utility model has overcome the deficiencies in the prior art, and highi degree of accuracy pressure regulator valve is provided, this device profile is reasonable, easy for installation, flexible operation and pressure regulation precision high, stable and reliable for performance.
For solving above-mentioned technical problem, the utility model by the following technical solutions: highi degree of accuracy pressure regulator valve, comprise pedal, spring, valve seat, valve rod, spool and valve body, described spool is positioned at the cavity of valve body and can moves axially along valve body; Described stem bottom is vertically fixed on the top of valve body by bolt, the top connecting valve seat of valve rod; Described pedal one end is movably connected in the top of valve seat, and the other end is unsettled, between the bottom of pedal and valve seat, goes back linking springs.
Described pedal is flexibly connected end and is connected on the step of valve seat.
Described pedal and valve seat are acute angle, and scope is between 0 °-60 °.
Described pedal can be along instantaneous pin direction rotation.
Described pedal is long strip.
Described spring is perpendicular to pedal.When pushes pedals, realize vertical pressing spring, press faster.
Compared with prior art, the beneficial effects of the utility model are:
1, in the utility model, between pedal and valve seat, the flexible of spring can be by jamming on pedal, the angle changing between pedal and valve seat realizes between 0 °-60 °, and angle variation gets final product regulation output pressure size, make pressure size can within the scope of 0-1MPa, realize stepless pressure regulation, pressure regulation precision is high.
2, the utility model adopts and manually carries out pressure regulation, disturbed by extraneous factor few, and performance is more reliable and more stable, between each parts, utilizes and is threaded, and it is more convenient that parts are changed in installation.
3, to be flexibly connected end be by being connected on the step that valve seat exceeds, being then flexibly connected by bolt to pedal, ensureing to rotate flexibly to go back difficult drop-off under prerequisite.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, reference character is expressed as: 1, pedal; 2, spring; 3, valve seat; 4, valve rod; 5, spool; 6, valve body.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in 1 figure, the utility model comprises pedal 1, spring 2, valve seat 3, valve rod 4, spool 5 and valve body 6, and spool 5 is positioned at the cavity of valve body 6 and can moves axially along valve body 6; Valve rod 4 bottoms are vertically fixed on the top of valve body 6 by bolt, the top connecting valve seat 3 of valve rod 4.Pedal 1 one end of the present embodiment is movably connected in the top of valve seat 3, and the other end is unsettled, between the bottom of pedal 1 and valve seat 3, goes back linking springs 2, and spring 2 is perpendicular to pedal 1.Pedal 1 is wherein flexibly connected end and is connected on the step of valve seat 3, and pedal 1 is acute angle with valve seat 3, and scope is between 0 °-60 °, and pedal 1 can be along instantaneous pin direction rotation, and pedal 1 is long strip.
When use, only need jam on pedal top Compress Spring, the principle balancing each other according to spring force and pressure, in the time that the pressure of spring is less than air pressure, valve cuts out, the active force of the pressurized air of the rubber voltage regulation diaphragm below of base below to diaphragm in the time that pressure is greater than the elastic force of spring, promotion diaphragm upwards arching is lifted off a seat and is passed air into air cavity, now valve rod moves under gas pressure, by the valve open on valve body, so just entering atmospheric air compressor by valve, the air that is filled with air cavity by air compressor dallies.Between pedal and valve seat, be acute angle, only need Compress Spring to get final product regulation output pressure size, make pressure size can within the scope of 0-1MPa, realize stepless pressure regulation, pressure regulation precision is high.It is few that this device is disturbed by extraneous factor, and performance is more reliable and more stable, between each parts, utilizes and be threaded, and replacing parts is installed more convenient.In addition, it is by being connected on the step that valve seat exceeds, being then flexibly connected by bolt that pedal is flexibly connected end, is ensureing to rotate flexibly to go back difficult drop-off under prerequisite.
Just can realize as mentioned above this model utility.
