Abstract
A protective cover used for a pressure regulating valve consists of a cover body and a skirt hem, wherein the skirt hem is in matched joint with the joint part of an upper valve cover and a valve seat of the pressure regulating valve in external profile, the inner wall of the skirt hem is provided with at least one vertical convex rib or groove, the upper valve cover is accommodated in a cavity of the cover body, and a gap is reserved. After the protective cover is adopted, a respiration hole in the upper valve cover of the pressure regulating valve can be enabled to be kept communicated with the atmosphere under any severe weather and environment conditions, so that the working life of the pressure regulating valve is greatly prolonged, and the working reliability of the pressure regulating valve is greatly improved.
Description
Technical field
The present invention relates to pressure regulator valve resist technology field, the protective housing that particularly a kind of pressure regulator valve is used.
Background technique
Be widely used in pressure regulator valve in fluid line mainly by regulating wheel shaft 1, Regulation spring 3, diaphragm 5, spool 13, lever 8, nozzle 9, advance fluid hose 10, go out fluid hose 6 and bonnet 4 and valve seat 11 and form, shown in Figure 1.Between bonnet 4 and valve seat 11, diaphragm 5 is housed, pressure regulator valve is divided into to upper and lower chamber 12,7, the galianconism end of lever 8 is provided with spool 13, and its long arm end is provided with pallet 14, and it is upper and fixing with diaphragm 5 center interlockings that this pallet 14 is placed in 5, diaphragm.Be provided with in upper chamber 12 and regulate wheel shaft 1 and Regulation spring 3, the upper end of spring joins with adjusting wheel shaft 1, and lower end and the pallet 14 above diaphragm 5 join.On bonnet 4, end face has spiracle 2, and upper chamber 12 is communicated with ambient atmosphere, when the upper and lower motion of diaphragm 5, air constantly from spiracle 2 go out into, realize the pressure regulation purpose.Indoor lever 8, spool 13, the nozzle 9 of being provided with of valve seat 11, be connected with nozzle 9 match activities.
When pressure regulator valve advance fluid hose 10 input high-pressure liquid the time, high-pressure liquid is washed spool 13 open by nozzle 9 and is entered lower chambers 7, diaphragm 5 is raised up, when upper chamber's 12 pressure during higher than barometric pressure, the interior air of upper chamber 12 is slowly discharged from spiracle 2, complete an exhalation process of pressure regulator valve, now, spool 13 is shut-off nozzle 9 gradually.When going out fluid hose 6, open, lower chambers 7 pressure diminish, and diaphragm 5 is recessed, spool 13 is opened, and high-pressure liquid enters lower chambers 7, now, upper chamber's 12 volumes increase, and when its pressure is less than barometric pressure, air enters through spiracle 2 breathing process that upper chamber 12 completes pressure regulator valve.In the pressure regulator valve working procedure, diaphragm 5 is epirelief or recessed ceaselessly, under lever 8 drives, between spool 13 and nozzle 9, also constantly closes thereupon or opens, and realizes the voltage stabilizing purpose of output fluid, to meet user's usage requirement.
As can be seen here, the spiracle 2 of bonnet 4 is in unimpeded state, pressure regulation, pressure stabilization function to pressure regulator valve are vital, because pressure regulator valve generally is arranged on outdoor open space or the poor occasion of indoor environment, when spiracle 2 by dust, foreign material, the rainwater mixture is clogging or in the winter time the time snow cover after spiracle 2, the air of upper chamber 12 can't normally pass in and out, and the pressure regulating action of pressure regulator valve is just malfunctioning, and accident will meet accident.If rainwater or dust are in spiracle 2 directly enters into upper chamber 12, can gather on diaphragm 5 and pallet 14, make diaphragm 5 bear extra gravity, have a strong impact on the precision of voltage regulation of pressure regulator valve, accident also can meet accident.If after having advanced rainwater (comprising acid rain) and dust in upper chamber 12, can cause corrosion to component and the bonnet 4 of upper chamber 12, cause pressure governor to lose voltage regulation function until damage.
Summary of the invention
The protective housing that the object of the present invention is to provide a kind of pressure regulator valve to use, it can guarantee that the spiracle of pressure governor bonnet all keeps unimpeded with atmosphere under any atrocious weather, ambient conditions, has improved the operating life of pressure governor and the reliability of work widely.
Technical solution proposed by the invention is such:
The protective housing that a kind of pressure regulator valve is used, described protective housing 21 is comprised of cover body 21-4 and shirt rim 21-1, this shirt rim 21-1 engages with seat interface external frame coupling with the bonnet of pressure regulator valve, be provided with at least one vertical convex tendon or groove 21-2 at shirt rim 21-1 inwall, the cavity 21-3 of described cover body 21-4 accommodates bonnet and leaves space.
21-1 inwall relative protective housing 21 central shafts in described shirt rim have camber angle α=2 °～6 ° of angles.Described shirt rim 1-1 inner wall even distribution has 2～4 vertical convex tendons or groove 21-2.When protective housing 21 adopts the sheet metal drawing and forming, its shirt rim 21-1 inwall is selected vertical groove 21-2.When protective housing 21 adopts injection molding, its shirt rim 21-1 inwall is selected vertical convex tendon 21-2.
Compared with prior art, the present invention has following remarkable result:
The protective housing that pressure regulator valve of the present invention is used is to be sleeved on the pressure regulator valve bonnet, the connecting part coupling interlocking of its shirt rim and pressure regulator valve bonnet and valve seat, set one or more than one convex tendons or the groove by the shirt rim inwall, make ambient atmosphere directly pass into the protective housing inner cavity and enter in the upper chamber of bonnet from the spiracle of bonnet, no matter blowing, rain, the severse weathers such as snow fall, the spiracle that can guarantee pressure regulator valve under complex environment is unblocked, rainwater (acid rain), the dust foreign material can not enter in bonnet, the existing whole potential safety hazards of former pressure governor have been got rid of fully, improved widely the operating life of pressure governor.The shirt rim of this protective housing, with appropriate tapering, can make it quick for installation easy to be reliable, can make again protective housing stack storage, convenient keeping and transportation.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing a kind of pressure governor.
Fig. 2 is the protective roof structure schematic diagram that the pressure regulator valve of one embodiment of the invention is used.
Embodiment
By following embodiment, the present invention is further elaborated.
Shown in Figure 2, the protective housing 21 that a kind of pressure regulator valve is used is comprised of cover body 21-4 and shirt rim 21-1.Shirt rim 21-1 engages with the joining portion external frame coupling of valve seat with the bonnet of pressure regulator valve.Be provided with at least one vertical convex tendon or groove 21-2 at shirt rim 21-1 inwall, the cavity 21-3 of cover body 21-4 accommodates bonnet and leaves space.Leave certain interval between end face on cover body 21-4 upper top bottom surface and pressure governor bonnet, make the spiracle of bonnet have at any time air to free in and out.
In the present embodiment, in shirt rim 21-1 inwall surrounding, be evenly equipped with 4 vertical convex tendon 21-2, its protective housing 21 is injection moldings.(when protective housing 21 is selected the sheet metal drawing and forming, its shirt rim 21-1 inwall is selected vertical groove 21-2.) 21-1 inwall relative protective housing 21 central shafts in shirt rim have camber angle α=2 °～6 ° of angles, to facilitate, interlocking and accumulating are installed.
During installation, directly protective housing 21 is embedded in to the bonnet of pressure regulator valve and the junction point of bonnet and valve seat gets final product, now, there is certain gap between protective housing 21 cover body 21-4 upper top inwalls and bonnet upper top, make spiracle air under any climatic environment state of bonnet can free in and out upper chamber's inner chamber of bonnet, guarantee that pressure governor normally, work reliably.
