Abstract

The utility model relates to an inclined stop valve which comprises a valve body and a valve core, wherein, the valve body is an inclined three-way pipe; the valve core is arranged in the inclined pipe; and a ring ridge end surface perpendicular to the axis line of the valve core is arranged in the cavity of the valve body. The inclined stop valve has the advantages of simple structure, low manufacture cost, large flow area, and small fluid resistance.

Description

The inclined stop valve

Technical field

The utility model relates to valve, and the stop valve that particularly circulation area is big, fluid resistance is little is made the field.

Background technique

Stop valve mainly is made of valve body and spool now.Referring to Fig. 1, valve body is three-way pipe always, and valve core axis is vertical with valve axis, be used for the descending spacing seam end face of spool in the valve body and be horizontally set on the fluid passage, like this, the fluid passage in the valve body be first level, more straight up, the bending shape of back level, thereby, the effective channel cross-section of fluid reduces, as, in import tube coupling internal diameter 24mm, entery and delivery port stenosis diameter only has 9mm, increase fluid resistance greatly, reduced water flow.The Chinese patent literature patent No.: 200410021962.1,2004100222129.9,200410022291.0,200410022471.9 etc. all belong to this class stretched formula stop valve.

The model utility content

The purpose of this utility model provides the inclined stop valve that a kind of circulation area is big, fluid resistance is little.

This novel purpose is achieved in that a kind of inclined stop valve, comprises, and valve body, spool, valve body are the bevel arm piece of being made up of straight tube and inclined tube; Spool is arranged in the inclined tube; Body cavity is provided with the seam end face vertical with valve core axis.

The inclined tube of above-mentioned composition valve body and straight tube are 45 ° of settings.

Above-mentioned spool is made up of screw rod, valve core rod and valve core housing, screw rod is located in the valve core housing rotationally, two O shapes on the screw rod are enclosed and the valve core housing drive fit, the cross section is that orthohexagonal valve core rod is inserted in the orthohexagonal hole of valve core housing versatilely, have the screw rod of left-handed thread to be connected with the valve core rod spiral on it, the valve core rod bottom is fixed with sealing gasket.

Above-mentioned valve body is the plastics bevel arm piece, is embedded with in its inclined tube as the metal nuts that is connected with the valve core housing spiral.

Compared with prior art, this novel beneficial effect is:

1, the circulation area of valve is big, and fluid resistance is little

Be 24mm in inlet/outlet tube coupling internal diameter, because spool and spool inlet/outlet tube coupling (actual is a straight tube) are oblique, particularly during 45 ° of obliques, the perfectly straight footpath of minimum stream, inlet/outlet place is 18mm in the valve body, be the twice of existing stretched formula stop valve, thereby the valid circulation area growth, simultaneously, fluid flow line also substantially only has a little bending, has reduced fluid resistance greatly.

2, simple in structure, cost is low

Spool adopts three component-assembled such as valve core housing, valve core rod and screw rod to form, and has characteristics simple in structure, easily manufactured, easy-to-disassemble and assemble.

3, this novelly is applicable to many fields, and valve body adopts plastics bevel arm pieces such as PP-R.PE.ABS to form with the embedded metal nut or metallic material bevel arm piece composition, have cost low, do not pollute, the characteristics of health.

4, adopt the design to cooperate and make the antitheft water valve of using with the existing anti-formula spool of usurping, need be opened with special tool during use.

Description of drawings

Fig. 1 is the structural drawing that existing valve ends valve;

Fig. 2 is an embodiment's of the utility model a structural drawing;

Fig. 3 is another embodiment's of the utility model a structural drawing.

Embodiment

Fig. 2 illustrates, this novel valve body 1 that comprises, and spool 2, valve body 1 is the bevel arm piece of being made up of straight tube and inclined tube; Spool 2 is arranged in the inclined tube; Valve body 1 inner chamber is provided with the seam end face 11 with spool 2 axis normal.Inclined tube and the straight tube of forming valve body 1 are 45 ° of settings (can adjust as required) between 30 °～60 °.Spool 2 is made up of screw rod 22, valve core rod 23 and valve core housing 24, screw rod 22 is located in the valve core housing 24 rotationally, two O shapes circle 22a on the screw rod 22 and valve core housing drive fit are (among Fig. 2 Fig. 4, handwheel 21 through screw at the screw rod top), the cross section is that orthohexagonal valve core rod is inserted in the orthohexagonal hole of valve core housing versatilely, have the screw rod of left-handed thread to be connected with the valve core rod spiral on it, the valve core rod bottom is fixed with sealing gasket 25.Valve core housing 24 is threaded (Fig. 4) with valve body 1 or flange is connected.Valve body 1 is the plastics bevel arm piece, is embedded with in its inclined tube as the metal nuts that is connected with valve core housing 24 spirals.Among Fig. 3, valve body 1 is a shown in Figure 1 novel skew T formula valve body.Spool is the existing anti-spool of usurping.The valve body top is connected with valve gap 31, triangular prism 32 is arranged at the screw rod top of spool, when using the special opening instrument, two tips of fork on tool using one end are stuck in two pit-holes on the valve cover surfaces, just can screw off valve gap 31, with the upper shield on the instrument the other end (endoporus is triangular prism), be enclosed within on the triangular prism 32, but just turn spool screw rod, make the spool upstream or downstream, realize the unlatching and the shutoff of valve.

This novel valve specification has Φ 20～Φ 160, and wherein, Φ 63 connects can adopt flange between upper valve body, the spool.
