Abstract
The utility model provides an array-oriented flow-stop air release valve with abrasion resistance , which mainly comprises a vale with lower valve cover and upper valve cover, a bracket which is provided with a turning nut, a valve rod and a hand-wheel etc. the utility model is characterized in that: the valve core and the valve rod are connected with each other by round groove and steel ball, the valve core is embed to the sealed device, an array-oriented cover with slot or hole is arranged at the sealed device, the valve core, the sealed device and the array-oriented cover are integrated with each other by bolt, the array-oriented cover always moves with the valve base, the valve core combined set moves with top-down in the guide tank which is fixed at the valve cover, the sealed device and the valve base, so as to realize to replace the existing flow-stop air release valve. The utility model has an array-oriented flow-stop air release valve with abrasion resistance which has good sealing performance and a log service life, and can replace the existing flow-stop air release valve.
Description
The utility model relates to a kind of mechanical type manual throttling by atmospheric valve, and it is specially adapted to into oil, gas industry.
At present, oil, the throttling of gas industry more application are by atmospheric valve, but the medium of existing valve all is directly to wash away spool, and impurity easily is piled up in sealing surface, and the damage sealing surface makes sealing effect bad.
The purpose of this utility model is to propose a kind of simple in structurely, reasonable in design on the basis of prior art condition, and it is convenient to manufacture, good airproof performance, and the life-span is long, can replace having now throttling and end that the guiding type of atmospheric valve is anti-to be washed away throttling and end atmospheric valve.
The purpose of this utility model is achieved through the following technical solutions.
A kind of guiding type is anti-to wash away throttling by atmospheric valve, it is mainly by the valve body that bottom flange, bonnet are installed, the upper bracket and the valve rod of rotating nut are housed, formations such as handwheel, MEDIA FLOW is to shown in the figure arrow in the valve body, when the turn handwheel, valve rod drives spool and Sealing that is fixed thereon and the guide sleeve that has bar hole or aperture move together.When opening of valves was closed, medium entered guide sleeve from valve seat orifice, flowed out from the hole of guide sleeve, had avoided directly washing away Sealing.And no matter guide sleeve open, cut out all the time in valve seat orifice, played leading role, and spool moves in guide, also can lead.Thereby its leading role of this valve is significantly better than other similar valves.Simultaneously, medium changes direction and flows out from the hole of guide sleeve, itself has played the effect of throttling step-down, also to the mechanical admixture in the medium, played filtration as landwaste etc., the eddy current that its produces has also been taken away the impurity on the sealing surface of seat, has made better tightness.
Fig. 1 is structural representation of the present utility model and embodiment.
The drawing explanation:
1, handwheel 2, upper bracket 3, bonnet 4, valve rod 5, steel ball 6, guide 7, spool 8, Sealing 9, guide sleeve 10, valve seat 11, attachment bolt 12, valve body 13, bottom flange
The utility model is done the explanation in a step below in conjunction with accompanying drawing:
A kind of guiding type is anti-to wash away throttling by atmospheric valve, and it mainly is made of the valve body 12 that bottom flange 13, bonnet 3 are installed, the handwheel 1 etc. that is fitted with the upper bracket 2 of rotating nut and is connected in valve rod 4.12 of bonnet 3 and valve bodies are fixed with guide 6, are equipped with valve seat 10 at guide 6 and 12 of valve bodies.7 of guide 6 and spools seal with " O " shape rubber ring, and spool 7 moves up and down in guide 6, spool 7 adopts annular groove and steel ball 5 to connect with valve rod 4, be fixed with Sealing 8 and guide sleeve 9 on the spool 7, they are linked to be an assembly, move up and down in guide 6 with valve rod 4, and guide sleeve 9 moves in the endoporus of valve seat 10 all the time, can play leading role, again because of having bar hole or aperture in the guide sleeve, when medium passes through, changed direction, thereby avoided directly washing away Sealing 8.From the hole by also having played the throttling step-down, the effect of filtration, the eddy current of generation has also been taken away the impurity on the valve seat 10, the reliability when also having guaranteed sealing.
Claims (2)
1, a kind of guiding type is anti-to wash away throttling by atmospheric valve, it is mainly by the valve body (12) that bottom flange (13) bonnet (3) is installed, be fitted with the upper bracket (2) of rotating nut and be connected in the handwheel formations such as (1) of valve rod (4), it is characterized in that spool (7) and valve rod (4) adopt annular groove and steel ball (5) to connect, spool (7) embeds Sealing (8), dress has the guide sleeve (9) of bar hole or aperture on the Sealing, spool (7) Sealing (8), guide sleeve (9) combines as a whole with attachment bolt (11), guide sleeve (9) motion in valve seat (10) all the time, spool (7) assembly parts is being fixed in bonnet (3) and valve body (12), move up and down in the guide (6) of valve seat (10).
2, guiding type according to claim 1 is anti-washes away throttling by atmospheric valve, the guide sleeve (9) that it is characterized in that spool (7), Sealing (8), has bar hole or an aperture forms a whole, and guide sleeve (9) moves up and down in valve seat (10) all the time.
