Description
Technical field
The utility model relates to a kind of convenient type diaphragm type pressure-reducing valve, belongs to the technical field of diaphragm type pressure-reducing valve.
Background technique
Existing diaphragm type pressure-reducing valve, mainly comprises valve body, valve gap, spool, Compress Spring.Spool is formed primarily of vavle shelf, valve rod, O type circle, filter screen, bolt, spring seat, diaphragm.The upper surface of diaphragm is fixed by the lower end surface of valve gap, and the lower surface of diaphragm is pressed on the step surface of the diaphragm chamber of valve body.The upper end of Compress Spring is provided with the screw thread catch and look nut that cooperatively interact, look nut is arranged on valve gap turnably, and the valve gap roof matched with look nut offers through hole, be convenient to the adjustment of instrument to look nut, finally realize screw thread catch and the decrement of Compress Spring is regulated; The lower end mounting spring seat of Compress Spring.Spring seat, diaphragm, valve rod are from top to bottom fixedly connected sequentially together by bolt.
During reduction valve work, hydraulic pressure acts on diaphragm bottom by the flow channel of vavle shelf, then by regulating the position of diaphragm with the spring force interaction force of upper end Compress Spring, thus control the aperture between valve rod and vavle shelf, play the effect controlling downstream hydraulic pressure.
There is following defect in this existing diaphragm type pressure-reducing valve:
1., when reduction valve is loaded on pipe-line system, spool needs to dismantle by external tool during disassembly, cleaning;
2. general tool dismounting is more difficult, lacks removal tool special.
Model utility content
The purpose of this utility model is to provide a kind of without the need to by external tool, just can by the convenient type diaphragm type pressure-reducing valve of spool dismounting.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of convenient type diaphragm type pressure-reducing valve, comprise valve body, valve gap, spool, Compress Spring, spool is primarily of vavle shelf, valve rod, bolt, spring seat, diaphragm is formed, the upper end of Compress Spring is provided with the screw thread catch and look nut that cooperatively interact, look nut is arranged on valve gap turnably, and the valve gap roof matched with look nut offers through hole, the lower end mounting spring seat of Compress Spring, bolt is by spring seat, diaphragm, valve rod is from top to bottom fixedly connected sequentially together, the upper-end surface of the head of described bolt, from bottom to top be disposed with connecting rod, lift block, lift block only can be inserted in valve gap by through hole with angle of inclination.
As the further setting of such scheme, the cross section of described lift block is polygonal or ellipse; When the cross section of lift block is polygonal, each limit length of side of lift block is all less than the diameter of through hole; When lifting the ellipsoidal cross section of block, major diameter is greater than through-hole diameter, and minor axis diameter is less than through-hole diameter.
The cross section of described lift block is regular polygon.
The cross section of described lift block is equilateral triangle.
Described connecting rod is cylindrical structure, and with bolt concentric.
The diameter of described connecting rod is less than the stud external diameter of bolt.
Each angle of described lift block is fillet.
The utility model convenient type diaphragm type pressure-reducing valve, when the clean spool of needs, first valve gap, Compress Spring, screw thread catch and look nut are taken off, then valve gap is inverted, then first tilt to stretch into the mode of valve gap by through hole with one jiao that lifts block, inserting in valve gap by lift block entirety, take finally valve gap as instrument, by valve core taking.After valve core taking, then according to same operation, valve gap is separated with lift block.
The utility model convenient type diaphragm type pressure-reducing valve, has set up lift block at the head of bolt, making bolt except having connection inner body function, also dismantling spool by coordinating with valve gap, without the need to extra frock.Like this, not only facilitate the use and maintenance that user is daily to reduction valve, do not affect overall product cost simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model convenient type diaphragm type pressure-reducing valve, comprise valve body 1, valve gap 7, spool, Compress Spring 5, spool is primarily of vavle shelf 2, valve rod 3, bolt 4, spring seat 10, diaphragm 11 is formed, the upper end of Compress Spring 5 is provided with the screw thread catch 6 and look nut 9 that cooperatively interact, look nut 9 is arranged on valve gap 7 turnably, and valve gap 7 roof matched with look nut 9 offers through hole 8, the lower end mounting spring seat 10 of Compress Spring 5, bolt 4 is by spring seat 10, diaphragm 11, valve rod 3 is from top to bottom fixedly connected sequentially together.Improvement of the present utility model is: in the upper-end surface of the head 41 of bolt 4, and be from bottom to top disposed with connecting rod 12, lift block 13, lift block 13 only can be inserted in valve gap 7 by through hole 8 with angle of inclination.
Wherein, the cross section of block 13 is lifted preferably in polygonal or ellipse.When the cross section of lift block 13 is polygonal, each limit length of side of lift block 13 is all less than the diameter of through hole 8.When lifting the ellipsoidal cross section of block 13, major diameter is greater than through hole 8 diameter, and minor axis diameter is less than through hole 8 diameter.
As preferred further, the cross section of lift block 13 is regular polygon.In the present embodiment, the cross section of lift block 13 is equilateral triangle.Connecting rod 12 is cylindrical structure, and with bolt 4 concentric.The diameter of connecting rod 12 is less than stud 42 external diameter of bolt 4.Each angle of lift block 13 adopts round-corner transition.
Shown in composition graphs 4, Fig. 5, Fig. 6, the utility model convenient type diaphragm type pressure-reducing valve, when the clean spool of needs, first valve gap 7, Compress Spring 5, screw thread catch 6 and look nut 9 are taken off, then valve gap 7 is inverted, then first tilts to stretch into the mode (as Fig. 4) of valve gap 7 with one jiao that lifts block 13 by through hole 8, lift block 13 entirety is inserted in valve gap 7, last with valve gap 7 for instrument, by valve core taking.After valve core taking, then according to same operation, valve gap 7 is separated with lift block 13.
By in the process of valve core taking, bolt 4 and valve gap 7 keep concentric, to guarantee to lift the state that can keep mutual holding between block 13 and valve gap 7 all the time, as shown in Figure 5, Figure 6.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
