Abstract
The utility model relates to a pressure regulating valve. The pressure regulating valve comprises a valve cover, a valve body, a pressure regulating rod, a pressure regulating spring, a pressure regulating spring seat, a diaphragm, a pressure regulating force transferring component, a filter screen, a reset spring, a return spring seat, a valve stem and a valve core. The pressure regulating valve is characterized in that the valve core is positioned in a core hole opened on the valve body, and the valve core and the valve body directly form a moving subsidiary and a sealing subsidiary. The filter screen is arranged on a gas inlet channel of the valve body. A via hole which communicates a diaphragm chamber with an air outlet is a waist-shaped bar hole or an oval bar hole or a dumb-bell-shaped bar hole. The pressure regulating valve has good pressure regulating performance, and the range of regulating pressure can be free selected from 0.2 mpa to 1.6 mpa. Compared with the existing valves, the volume of the pressure regulating valve is reduced more than 50%, and the weight of the pressure regulating valve is reduced by 50%-60%.
Description
The utility model relates to the direct-acting type pressure regulator valve that a kind of low-temperature (low temperature) vessel pipe-line system is used.
Existing pressure regulator valve volume weighs greatly, and its main cause is unreasonable structure.For example: valve seat is independent member; Filter screen is designed to cylindric, is sleeved on the valve seat outer surface; The via hole of being opened on the valve body that diaphragm chamber is communicated with the air outlet is a circular port.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of improved pressure regulator valve is provided, and not only pressure regulating performance is good for it, and volume is little, in light weight.
In order to realize goal of the invention, the utility model has adopted following technological scheme: 1, offer spool bore on valve body, the step at this spool bore and its top forms valve seat, and spool is positioned at spool bore, and direct and valve body forms sliding pair and sealing pair; 2, the above-mentioned valve seat that is located immediately on the valve body is imposed heat treatment; 3, the shape and size of filter screen and valve body air intake passage are complementary, and are installed on the air intake passage of valve body; 4, guarantee the latus rectum d of throat
KWith inside nominal diameter d
NBetween satisfy d
K〉=0.8d
NThe sectional area of the via hole that diaphragm chamber is communicated with the air outlet that 5, makes on the valve body to be opened is greater than the sectional area of air outlet passage.Its structure comprises component such as screw press, valve gap, pressure adjusting spring, pressure adjusting spring seat, diaphragm, pressure regulation Force transmission parts, valve body, filter screen, Returnning spring, return spring holder, spool and valve rod.
In order to realize goal of the invention better, the utility model also improves the sectional shape of the via hole that diaphragm chamber is communicated with the air outlet offered on the valve body, it is designed to waist shape strip hole or oval strip hole or dumbbell-like shape strip hole, so both can reduce the volume of valve, can guarantee the sectional area of its sectional area again greater than the air outlet passage.In addition, also the manufacture method of valve gap, valve body is improved, replaced conventional cast with precision casting.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of structural drawing of the pressure regulator valve that proposes according to the utility model;
Fig. 2 is the plan view of valve body among Fig. 1, and the via hole that diaphragm chamber is communicated with the air outlet is waist shape strip hole;
Fig. 3 is the schematic representation of oval strip via hole that diaphragm chamber is communicated with the air outlet;
Fig. 4 is the schematic representation of dumbbell-like shape strip via hole that diaphragm chamber is communicated with the air outlet.
Concrete structure below in conjunction with the description of drawings present embodiment.
As shown in Figure 1, pressure regulator valve in the present embodiment comprises screw press 1, valve gap 2, pressure adjusting spring 3, pressure adjusting spring seat 19 and 4, diaphragm 5, pressure regulation Force transmission parts 6, valve body 7, filter screen 8, Returnning spring 11, return spring holder 12, spool 14 and valve rod 18 up and down, assembling mode is as follows: diaphragm 5 is installed between the junction plane of valve gap 2 and valve body 7, up and down pressure adjusting spring seat 19,4 and on the pressure adjusting spring 3 adorned be positioned at diaphragm and contact with diaphragm 5 with cavity and time pressure adjusting spring seat 4 that valve gap forms; Screw press 1 forms screw pair with valve gap 2 and its underpart connects pressure adjusting spring seat 19; Pressure regulation Force transmission parts 6 is positioned at diaphragm 5 and links to each other with the diaphragm chamber 16 of valve body 7 formation and with diaphragm; 15 (as shown in Figure 2) of waist shape strip via hole that offer suction port 9, air outlet 13, larynx hole 17, spool bore 10 on the valve body 7 and diaphragm chamber 16 is communicated with air outlet 13, spool bore 10 forms valve seat with the step at its top, this valve seat be positioned under the larynx hole and with larynx hole coaxial line; One end of valve rod 18 and pressure regulation Force transmission parts 6 form sliding pair, and the other end links to each other with spool 14 upper ends; Spool 14 is positioned at spool bore 10, and direct and valve body forms sliding pair and sealing pair; Returnning spring 11, return spring holder 12 are positioned at the lower end of spool 14, and Returnning spring 11 links to each other with spool 14; Filter screen 8 is a cup-shaped, and its size and air intake passage are complementary, and is installed on the air intake passage of valve body.
For fear of oxide etch and accident situation such as be used for blasting on the oxygen pipeline, valve body 7 and valve gap 2 are done by stainless steel or copper, adopt precision casting.
Concrete structure of the present utility model is not limited to the foregoing description, and for example, spool 14 can also be designed to overall structure with valve rod 18, and the via hole 15 that diaphragm chamber 16 is communicated with air outlet 13 can also be designed to oval strip hole or dumbbell-like shape strip hole.
The utlity model has following advantage:
1, pressure regulating performance is good, and range of regulation can freely be selected at 0.2MPc～1.6MPc.
2, volume is little, in light weight, compare with existing similar pressure regulator valve, volume reduce 50% with On, weight reduces 50%～60%.
3, because volume reduces, weight reduces, and both can save material, reduce cost, again just In installation.
