Description
Technical field
The utility model is related to valve, especially a kind of check-valves.
Background technology
Check-valves is automatically closed and seals by pressure medium realization, is mainly used for preventing medium from flowing backwards, and protects in pipeline
Pump and key equipment, be applicable in a variety of media, the oblique flap valve that client uses in the prior art be elongated tradition tiltedly
Flap valve, valve body are two-piece type structure, are connected by flange bolt, and the installation needs of valve shaft and flap are opened on valve body
Hole, manufacture and processing cost are all higher, and are not suitable for high temperature and high pressure condition there are leakage point on valve body.
Utility model content
In order to solve the shortcomings of the prior art, the utility model provides a kind of compact-sized, sealed reliable interior
Formula is put to pressing from both sides oblique valve check-valves.
The oblique valve check-valves of a kind of built-in type opposite clip in the utility model, including valve body, locating piece, guide pad, valve shaft and
Flap；Valve inner is equipped with medium runner, be medium inlet on the right side of medium runner, left side is media outlet, medium runner middle part
Equipped with inclined seal boss, seal boss forms the closing means of medium runner with flap；Flap on both sides of the middle is equipped with positioning
Flap is rotatably mounted on valve body by ear, valve shaft through chucking lug；Locating piece is mounted on by screw on valve body, guide pad
On locating piece, valve shaft both ends are connected by spacer ring with guide pad, on valve shaft on the outside of flap and medium runner inner wall it
Between be equipped with torsional spring, torsional spring is for making flap be fitted in seal boss.Compact-sized, structure length only has tradition tiltedly flap-type non-return
Valve 1/8th arrives a quarter, small, light-weight, and weight only has 1 to four/15ths points of the oblique flap valve of tradition
One of, the pressure loss is smaller, and flap is closed rapidly, quick closedown can be realized before medium counter flow, dependable performance only relies on valve
Valve self gravitation can be realized flap and close and seal, and sealing performance is reliable, and service life is long, applied widely, and installation is safeguarded
It is more convenient, and operation and maintenance cost is relatively low.
Preferably, it is provided with nameplate on the outside of valve body.User is facilitated to differentiate using model, it is easy to use.
Preferably, seal boss inclination angle is 10 ~ 15o.Sealing effect is good, easy to use.
The beneficial effects of the utility model：Compact-sized, structure length only has tradition, and tiltedly flap valve 1/8th arrives
A quarter, small, light-weight, weight only has 1st/15th of the oblique flap valve of tradition to arrive a quarter, pressure damage
Mistake is smaller, and flap is closed rapidly, quick closedown can be realized before medium counter flow, dependable performance only relies on flap self gravitation
Flap can be realized to close and seal, sealing performance is reliable, and service life is long, applied widely, and installation is easily serviced, and
Operation and maintenance cost is relatively low.
Description of the drawings
Fig. 1 is a kind of oblique valve check valve structure schematic diagram of built-in type opposite clip.
Fig. 2 is a kind of oblique valve check valve structure schematic diagram of built-in type opposite clip.
It is marked in figure：1st, valve body, 2, locating piece, 3, guide pad, 4, valve shaft, 5, flap, 6, spacer ring, 7, torsional spring, 8, screw.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but this should not be interpreted as the utility model
The scope of above-mentioned theme is only limitted to above-described embodiment.
Such as Fig. 1-2, a kind of oblique valve check-valves of built-in type opposite clip, including valve body 1, locating piece 2, guide pad 3, valve shaft 4 and valve
Valve 5；Valve body 1 is internally provided with medium runner, be medium inlet on the right side of medium runner, left side is media outlet, medium runner middle part
Equipped with inclined seal boss, seal boss forms the closing means of medium runner with flap 5；5 on both sides of the middle of flap is equipped with fixed
Flap 5 is rotatably mounted on valve body 1 by position ear, valve shaft 4 through chucking lug；Locating piece 2 is mounted on valve body 1 by screw 8
On, guide pad 3 is mounted on locating piece 2, and 4 both ends of valve shaft are connected by spacer ring 6 with guide pad 3, in 5 outside of flap on valve shaft 4
Torsional spring 7 is equipped between medium runner inner wall, torsional spring 7 is used to that flap 5 to be made to be fitted in seal boss.Compact-sized, structure is long
Degree only has tradition, and tiltedly flap valve 1/8th is to a quarter, and small, light-weight, weight only has tradition tiltedly flap-type non-return
/ 15th of valve arrives a quarter, and the pressure loss is smaller, and flap is closed rapidly, and quick pass can be realized before medium counter flow
It closes, dependable performance, only relies on flap self gravitation and flap closing and sealing can be realized, sealing performance is reliable, and service life is long,
Applied widely, installation is easily serviced, and operation and maintenance cost is relatively low.
