Description
[technical field]
The utility model relates to valve technology field, specifically a kind of adjustable compression release valve.
[background technique]
Before this, high residential building supplies water and reduction valve will be installed before entering every product reduce pressure, and the import and export of reduction valve will be equipped with pressure gauge respectively, also will add fixed filter, a main valve also will be installed in front at all these equipment, uses during in order to indoor pipeline and equipment installation and maintenance.After all these equipment are contacted, form a valve group, traditional reduction valve group is formed by the pipe fitting serial connection of pipe fitting, arm reduction valve and the tipping delivery gauge of ball valve, filter, tipping inlet pressure table, take very big space, and to there be six interfaces to connect at least, install cumbersomely, leakage point is many, and the cost of whole valve group is higher.
[summary of the invention]
The technical problems to be solved in the utility model is: provide a kind of under the prerequisite that does not reduce original valve group function, the adjustable compression release valve of reduced volume, and easy-to-install greatly.
The technical solution of the utility model is as follows: a kind of adjustable compression release valve, it comprises the stop valve part, filtration fraction, pressure indicating section and reduction valve part, it is characterized in that: reduction valve partly comprises spool and flap, the draw-in groove that the spool middle part has a circle to protrude, spool under the draw-in groove partly inserts in the flap and with the flap screw thread and links to each other, be provided with sealing gasket between a bit of spool under the draw-in groove and the flap, establish the main regulation spring above the spool, establish auxiliary spring below the flap, establish one above the main regulation spring and regulate plug screw, regulate the plug screw top one groove for rotation adjusting usefulness is arranged, above regulating plug screw a nut is arranged, a plug is established in the valve body bottom below the auxiliary spring, be provided with seal ring between flap and the plug, reduction valve spool hypomere is a hollow tube, and the hole of offering with the spool side forms the fluid passage, and this passage is communicated with the valve body bottom cavity of reduction valve downstream below flap.
The stop valve part of ingress, described front partly is integrated with the reduction valve of back and forms a valve body, and filtration fraction comprises the filter screen that is located at ingress or stop valve inside, and the pressure indicating section includes mouth pressure table and delivery gauge.
The utility model beneficial effect: lump valve function, filtering function, decompression voltage stabilizing function, pressure deixis, and have that each functional part is rationally distributed, characteristics such as the ingenious uniqueness of structure, volume are small and exquisite, be fit to promote the use of.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is profile frame figure of the present utility model.
[embodiment]
Referring to Fig. 1, a kind of adjustable compression release valve described in the utility model, it comprises stop valve part, filtration fraction, pressure indicating section and reduction valve part, the stop valve part 1 of ingress, front is integrated with the reduction valve part 2 of back and forms a valve body; Stop valve partly is provided with handwheel 17; Filtration fraction comprises a circle filter screen 18 that is located at outside the stop valve spool; The pressure indicating section includes mouth pressure table 11 and delivery gauge 12; Reduction valve partly comprises spool 3 and flap 4, the draw-in groove 7 that the spool middle part has a circle to protrude, spool under the draw-in groove partly inserts in the flap and with the flap screw thread and links to each other, be provided with sealing gasket 19 between a bit of spool under the draw-in groove and the flap, be provided with main regulation spring 5 above the spool, be provided with auxiliary spring 8 below the flap, establish one above the main regulation spring 5 and regulate plug screw 13, above regulating plug screw 13 nut 10 is arranged, a plug 9 is established in auxiliary spring 8 following valve body bottoms; Be provided with O-ring seals 15 between reduction valve valve core piston 6 and the valve wall.
Regulating plug screw 13 tops has a groove 14, can insert wherein with screw-driver, regulates the size of main spring power with this, promptly sets outlet pressure.
Working principle of the present utility model is as follows: open stop valve, medium enters the reduction valve cavity of resorption by inlet (A represents water (flow) direction) through the stop valve flap, reduce through pressure after the throttling of reduction valve valve port again and enter reduction valve epicoele and outlet, the medium that enters epicoele acts on valve core piston 6 bottoms, and this power and spool top main spring power act on spool altogether.When equilibrium of forces up and down, flap is in certain position, and outlet pressure is certain; If spring force increases, spool moves down, and it is big that outlet pressure becomes.If spring force diminishes or outlet pressure increases, spool moves up, and outlet pressure diminishes thereupon and returns to original value.Therefore, this reduction valve also has voltage stabilizing function.
Reduction valve spool hypomere is a hollow tube, and the hole of offering with the spool side 16 forms fluid passages, and a fluid part that enters the reduction valve epicoele is gone out from outlet, the valve body bottom cavity 20 of another part below the fluid passage in hole 16 enters the reduction valve flap.Owing to be provided with O-ring seals 15 between flap 4 and the plug 9, so this cavity 20 can form pressure chamber.
When outlet pressure increased, the pressure of the cavity 20 below the flap increased, and the power that flap is made progress increases, and flap moves upward, and valve turns down, and outlet pressure reduces, and therefore, above-mentioned fluid passage can be played auxiliary adjustment, be helped the effect of voltage stabilizing.
Up resilience after main regulation spring 5 follows the string, when making flap can't move upward throttle down, rely on auxiliary spring 8 can help flap to move upward and throttle down, therefore, auxiliary spring 8 can play balance spring power, improves degree of regulation and auxiliary effect of closing valve.
