Abstract
The invention discloses an erosive wear resisting angle-type valve. The erosive wear resisting angle-type valve comprises a valve body, a valve clack, a valve seat and a valve rod. A medium inlet channel and a medium outlet channel are formed in the valve body, the valve seat is installed in the valve body and correspondingly located at the end, close to the medium outlet channel of the valve body, of the valve body, a valve clack sealing part is arranged between the valve clack and the valve seat, the valve clack sealing part is fixed to the valve clack, a sealing part offset hole axially penetrating through the valve clack sealing part is formed in the valve clack sealing part, and a valve seat offset hole axially penetrating through the valve seat is formed in the valve seat. The inner diameter of the sealing part offset hole and the inner diameter of the valve seat offset hole are both smaller than the inner diameter of the medium outlet channel in the valve body and the inner diameter of the medium inlet channel in the valve body. When the valve is totally opened, the sealing part offset hole and the valve seat offset hole are aligned and communicated. When the valve is closed, the sealing part offset hole and the valve seat offset hole are totally staggered. By the adoption of the structure, the service life of the erosive wear resisting angle-type valve can be effectively prolonged.
Description
Technical field
The present invention relates to a kind of angle type valve.
Background technique
At present, in existing a lot of pipe-line system, angle type valve is all housed, for being switched on or switched off of control piping system, but because some pipe-line system gathers pipe-line system as underground gas, in the gatherer process of underground gas, often there are the hard solid particle polluters such as silt to sneak in the gas of circulation, therefore the angle type valve that needs people regularly to open in pipe-line system discharges these impurity, and in the time that valve is unlocked, because pipe-line system itself all exists certain pressure medium, therefore under the effect of pressure medium, these impurity can form high speed circulation discharge in valve, thereby valve is caused to serious erosive wear, greatly shorten the working life of valve.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of angle type valve of the protection against erosion wearing and tearing that can effectively increase the service life.
For achieving the above object, the invention provides a kind of angle type valve of protection against erosion wearing and tearing, comprise valve body, flap, valve seat, valve rod, valve body is provided with medium inlet passage and media outlet passage, valve seat is loaded in valve body and corresponding this end being positioned near valve body media outlet passage, flap is loaded on valve seat, valve rod is arranged in valve body, valve rod is positioned at the inner and the flap of valve body to be fixed, valve rod passes on the outer end outside valve body driving mechanism is housed, described valve rod is coaxial with valve seat, between described valve rod and flap, be also provided with the Compress Spring for flap being pressed to valve seat, between described flap and valve seat, be provided with flap Sealing, and described flap Sealing and flap are fixed, described valve seat is fixed on valve body by locating stud, described flap Sealing is provided with the Sealing offset hole of axial perforation flap Sealing, described valve seat is provided with the valve seat offset hole of axial perforation valve seat, the internal diameter of described Sealing offset hole and valve seat offset hole is all less than the internal diameter of media outlet passage and medium inlet passage on valve body, and when valve is during in full open state, described Sealing offset hole and valve seat offset hole are just to connecting, when valve is during in closed condition, described Sealing offset hole and valve seat offset hole stagger completely.
The invention has the beneficial effects as follows: adopt said structure, the medium entering due to medium inlet passage on valve body is in the present invention discharged to media outlet passage through Sealing offset hole and valve seat offset hole, and the internal diameter of described Sealing offset hole and valve seat offset hole is all less than the internal diameter of medium inlet passage on valve body, therefore when valve is during in full open state, on valve body, the circulation area of the interior medium of medium inlet passage is by the circulation area of medium in Sealing offset hole and valve seat offset hole, thereby greatly slow down the speed that medium enters valve body and circulates in valve body media inlet passage, and then effectively weaken the erosive wear power to the each parts of valve when medium enters valve body, impurity is after Sealing offset hole and valve seat offset hole, and because the internal diameter of described Sealing offset hole and valve seat offset hole is also less than the internal diameter of valve body media outlet passage, therefore medium at this moment can be accelerated flow velocity, discharges fast thereby be conducive to impurity.Be the resistance to erosion polishing machine that further improves valve, described flap Sealing and valve seat can preferably adopt to be made as high-abrasive materials such as cemented carbide or potteries simultaneously.
It is coaxial with valve seat offset hole that the present invention can further be set to the media outlet passage of described valve body.
Adopt further and arrange; the media outlet passage of described valve body adopts coaxial setting with valve seat offset hole; can make through valve seat offset hole discharged to the impurity of valve body media outlet passage can be from the center of valve body media outlet passage through, thereby valve body media outlet passage is better protected.
The present invention also can further be set to be equipped with seal ring between described valve seat outer peripheral surface and valve body and between flap Sealing outer peripheral surface and valve body.
Adopt further and arrange, can effectively improve the overall sealing performance of angle type valve.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Provide as shown in Figure 1 a kind of angle type valve of protection against erosion wearing and tearing, comprise valve body 1, flap 2, valve seat 3, valve rod 4, valve body 1 is provided with medium inlet passage 11 and media outlet passage 12, valve seat 3 is loaded in valve body 1 and corresponding this end being positioned near valve body media outlet passage 12, flap 2 is loaded on valve seat 3, valve rod 4 is arranged in valve body 1, it is fixing that valve rod 4 is positioned at the inner and the flap 2 of valve body 1, valve rod 4 passes driving mechanism 5 is housed on the outer end outside valve body 1, described valve rod 4 is coaxial with valve seat 3, between described valve rod 4 and flap 2, be also provided with the Compress Spring 6 for flap 2 being pressed to valve seat 3, between described flap 2 and valve seat 3, be provided with flap Sealing 7, and described flap Sealing 7 is fixing with flap 2, described valve seat 3 is fixed on valve body 1 by locating stud 8, described flap Sealing 7 is provided with the Sealing offset hole 71 of axial perforation flap Sealing 7, described valve seat 3 is provided with the valve seat offset hole 31 of axial perforation valve seat 3, the internal diameter of described Sealing offset hole 71 and valve seat offset hole 31 is all less than the internal diameter of media outlet passage 12 and medium inlet passage 11 on valve body 1, and when valve is during in full open state, described Sealing offset hole 71 and valve seat offset hole 31 are just to connecting, when valve is during in closed condition, described Sealing offset hole 71 staggers completely with valve seat offset hole 31.The media outlet passage 12 of described valve body 1 preferably and valve seat offset hole 31 coaxially arrange.Between described valve seat 3 outer peripheral surfaces and valve body 1 and between flap Sealing 7 outer peripheral surfaces and valve body 1, be equipped with seal ring 9.
