Abstract
The utility model discloses an electric flange stop valve, including electric actuator, valve rod, valve clack and valve body, the valve clack is connected to the valve rod, the valve clack that electric actuator driven valve pole and be connected with the valve rod reciprocates control flap and opens and close, the valve body is provided with fluid passage, be equipped with the acceleration piece of screw thread form on the inner wall of passageway of flowing through. An object of the utility model is to provide an electronic flange stop valve, its advantage is that the fluid velocity of flow when the valve body fluid can be reduced greatly around the input deviation.
Description
Technical field
The utility model relates to valve field, and more particularly, it relates to a kind of electronic Flange Globe Valves.
Background technique
Stop valve is widely used in the middle of life, comprises Electric Actuated Stop Valves and pneumatic stopping valve, and Electric Actuated Stop Valves is generally standard-sized sheet closed, and its advantage is that opening and closing time is short, and structure is simple.But stop valve is unlike safety check, flow control valve, the valve of ball valve and membrane valve etc. kind, because the fluid passage of stop valve is meander configuration, and the valve of other kinds belongs to through-type, usual fluid passage comprises two curved parts, so through stop valve body fluid its flow through stroke for the valve body of other valve kind distance longer, so convection cell can produce certain obstruction, the speed making fluid original declines to some extent, so fluid is in valve body, certain deviation can be there is in the flow velocity of entrance and the flow velocity of outlet, potential energy can reduce comparatively speaking greatly, to such an extent as to occur that the pressure that fluid finally flows is inadequate, error to some extent.
At present, a lot of patents that market occurs, the Chinese patent that the patent No. is CN201010611170.5 as disclosed and another patent No. are the Chinese patent of CN201310726100.8, it is electronic without jig block stop valve and a kind of pile top of nuclear power station exhaust stop valve that title is respectively core one-level, all can there is the flow velocity of fluid through out-of-date fluid problem devious before and after input.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of electronic Flange Globe Valves, and its advantage is that the flow velocity of fluid through valve body fluid deviation before and after input can be reduced greatly.
For achieving the above object, the utility model provides following technological scheme:
A kind of electronic Flange Globe Valves, comprise Electric actuator, valve rod, flap and valve body, described valve rod is connected to flap, described Electric actuator actuate valve stem and the flap be connected with valve rod move up and down control valve and open and close, described valve body is provided with fluid passage, described in flow through passage inwall be provided with screw-shaped and accelerate part.
By adopting technique scheme, fluid is when flowing into the entrance of valve body, because acceleration part is shape of threads, produce and play certain mechanical function, under the condition of variable scarcely (initial velocity and flow constant when), the potential energy of fluid can be increased, can effectively make fluid along the instantaneous velocity of the lines raising of acceleration part itself, thus can solve the flow velocity of fluid through fluid passage fluid problem devious before and after input.
The utility model is set to further: the opposing one side of described two flanges is provided with soft sealing pad.
The utility model is set to further: described soft sealing pad adopts silica gel.
By adopting technique scheme, when stop valve is connected with pipeline, better tightness is more stable.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of the utility model electronic Flange Globe Valves embodiment when closing;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the sectional drawing of the utility model electronic Flange Globe Valves embodiment when opening;
Fig. 4 is the B portion enlarged view of Fig. 3.
Reference character: 1, Electric actuator; 2, valve rod; 3, flap; 4, fluid passage; 5, soft sealing pad; 6, part is accelerated.
Embodiment
Referring to figs. 1 through Fig. 4, the electronic Flange Globe Valves embodiment of the utility model is described further.
A kind of electronic Flange Globe Valves, comprise Electric actuator 1, valve rod 2, flap 3 and valve body, described valve rod 2 is connected to flap 3, described Electric actuator 1 actuate valve stem 2 and the flap 3 be connected with valve rod 2 move up and down control valve and open and close, described valve body is provided with fluid passage 4, described in flow through passage 4 inwall be provided with screw-shaped and accelerate part 6.Make described valve interior wall screw-shaped accelerate part 6 like this and can solve the flow velocity of fluid fluid when fluid passage 4 in input front and back problem devious.
In fact, fluid is when flowing into the entrance of valve body, owing to accelerating part 6 in shape of threads, produce and play certain mechanical function, under the condition of variable scarcely (initial velocity and flow constant when), the potential energy of fluid can be increased, can effectively make fluid can along the instantaneous velocity of lines raising itself accelerating part, again because there is certain radian the fluid passage 4 of its valve body of stop valve in real life, there is the position of some flexion torsions, so may produce certain obstruction by convection cell, the speed making fluid original declines to some extent.Fluid whole flow condition in fluid passage 4 first adds to subtract afterwards, accelerates part make fluid at current difference before entering valve body and behind fluid passage 4 apart from shortening to some extent so set up by the inwall namely flowing through passage 4 at valve interior wall.
In a particular embodiment, between described valve rod 2 and flap 3, be connected with pin, together with described valve rod 2 is fixed by a pin to flap 3.The opposing one side of described two flanges is provided with soft sealing pad 5.Described soft sealing pad 5 adopts silica gel.When making stop valve be connected with pipeline like this, better tightness is more stable.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
