Description
Technical field
The utility model relates to a kind of novel reduction valve, the Depressure valve that especially a kind of function with non-return also can prevent main valve control room from blocking.
Background technique
Reduction valve comprises main valve, one-way valve, needle-valve, ball valve, main valve comprises valve body, valve disc, valve gap and accessory thereof, space between valve disc and valve gap is main valve control room, valve seat is located at the friendship neighbour place between intake tunnel and exhalant canal, needle-valve is arranged on the water inlet pilot line in connection intake tunnel and main valve control room, ball valve, pilot valve is arranged on the water outlet pilot line in connection exhalant canal and main valve control room, the effect of decompression can be played, but common reduction valve does not have the function of non-return, need to connect with safety check, add cost, simultaneously, after impurity in water enters main valve control room, result in blockage, affect the normal work of main valve.
Model utility content
The purpose of this utility model is to increase the function of traditional relief valve, and provides a kind of and have the function of non-return and the Depressure valve preventing that main valve control room from blocking.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of novel reduction valve, comprise main valve, needle-valve, ball valve, pilot valve, described main valve comprises valve body, valve disc, valve gap, space between described valve disc and valve gap is main valve control room, described valve seat is located at the friendship neighbour place between intake tunnel and exhalant canal, described needle-valve is arranged on the water inlet pilot line in connection intake tunnel and main valve control room, described ball valve, pilot valve is arranged on the water outlet pilot line in connection exhalant canal and main valve control room, the water inlet pilot line connecting intake tunnel and main valve control room installs one-way valve and micro-shape filter, described one-way valve, before micro-shape filter is located at needle-valve, the water inlet pilot line connecting intake tunnel and main valve control room is arranged in order.
Advantage of the present utility model and good effect are: on water inlet pilot line, be provided with one-way valve, increase the check function of main valve, install micro-shape filter and can filter out impurities in water, make impurity not affect the normal work of main valve, extend working life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure
1. main valve, 2. one-way valve, 3. micro-shape filter, 4. needle-valve, 5. ball valve, 6. pilot valve, 7. valve body, 8. valve disc, 9. valve gap, 10. main valve control room, 11. valve seats, 12. intake tunnels, 13. exhalant canals, 14. water inlet pilot line, 15. water outlet pilot line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of novel reduction valve, comprise main valve 1, needle-valve 4, ball valve 5, pilot valve 6, described main valve 1 comprises valve body 7, valve disc 8, valve gap 9, space between described valve disc 8 and valve gap 9 is main valve control room 10, the friendship neighbour that described valve seat 11 is located between intake tunnel 12 and exhalant canal 13 locates, described needle-valve 4 is arranged on and connects intake tunnel 12 with on the water inlet pilot line 14 in main valve control room 10, described ball valve 5, pilot valve 6 is arranged on and connects exhalant canal 13 with on the water outlet pilot line 15 in main valve control room 10, the water inlet pilot line 14 connecting intake tunnel 12 and main valve control room 10 installs one-way valve 2 and micro-shape filter 3, described one-way valve 2, before micro-shape filter 3 is located at needle-valve 4, the water inlet pilot line 14 connecting intake tunnel 12 and main valve control room 10 is arranged in order, one-way valve 2 makes reduction valve be provided with the function of non-return simultaneously, micro-shape filter 3 can filter out the impurities in water entered in main valve control room 10, the impurity existed in water is made not affect the normal work of main valve 1, extend working life, make Stress control more accurate.
A kind of novel reduction valve, comprise main valve 1, one-way valve 2, micro-shape filter 3, needle-valve 4, ball valve 5, pilot valve 6, main valve 1 comprises valve body 7, valve disc 8, valve gap 9, space between valve disc 8 and valve gap 9 is main valve control room 10, the friendship neighbour that valve seat 11 is located between intake tunnel 12 and exhalant canal 13 locates, one-way valve 2, micro-shape filter 3, needle-valve 4 are arranged on and connect intake tunnel 12 with on the water inlet pilot line 14 in main valve control room 10, ball valve 5, pilot valve 6 are arranged on and connect exhalant canal 13 with on the water outlet pilot line 15 in main valve control room 10
When fluid is fed water by intake tunnel 12, water flows through one-way valve 2, micro-shape filter 3, needle-valve 4 enter main valve control room 10, and the pressure of exhalant canal 13 is applied on pilot valve 6 by water outlet pilot line 15.When setting value higher than pilot valve 6 of the pressure of exhalant canal 13, pilot valve 6 cuts out.Main valve control room 10 stops draining, and now main valve control room 10 internal pressure raises and closes main valve 1, and the pressure of exhalant canal 13 no longer raises.When the pressure of exhalant canal 13 drops to pilot valve 6 setting pressure, pilot valve 6 is opened, main valve control room 10 draining.Water displacement due to pilot valve 6 and ball valve 5 is greater than the inflow of needle-valve 4, main valve control room 10 pressure drop.The pressure of exhalant canal 13 makes main valve 1 open.At steady state, the water inlet in main valve control room 10 is identical with water displacement, and main valve 1 aperture is constant, the pressure stability of exhalant canal 13.Can by regulating the design load of setting exhalant canal 13 pressure of pilot valve 6.
When intake tunnel 12 stops supplying water, if the water of exhalant canal 13 starts backflow, a part of recirculation water enters main valve control room 10 through ball valve 5 and pilot valve 6, because one-way valve 2 acts on, recirculation water can not flow out from main valve control room 10, causes main valve control room 10 to boost gradually, slowly closes main valve 1.
Above embodiment is to invention has been detailed description, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
