Abstract
The invention relates to the technical field of valves, and specifically relates to a steam trap valve. The steam trap valve comprises an upper valve body, and a lower valve body which is integrally connected with the upper valve body; the upper valve body is provided with a drainage channel; the lower valve body is provided with an inlet channel which is communicated with the drainage channel; the steam trap valve is characterized in that inside the lower valve body is fixedly provided with a cone-shaped supporting block, the inlet channel penetrates the upper and lower end surfaces of the cone-shaped supporting block, and a cover which covers the outlet port of the inlet channel of the cone-shaped supporting block, one end of the cover is open, and the other end thereof is closed, the opening end of the cover is greater than the minimal size of the outer surface of the cone-shaped supporting block but less than the maximum size of the outer surface; inside the lower valve body is provided with a sealing block for sealing the drainage channel, and a connecting rod mechanism which is arranged between the cover and the sealing block and used for releasing the sealing block from the drainage channel when the cover rises up. The steam trap valve is simple in structure, reasonable in design, and is able to conduct steam smoothly, thereby meeting the usage requirements of steam equipment.
Description
Technical field
The present invention relates to valve technology field, be specifically related to a kind of steam and dredge stream valve.
Background technique
On some steaming plants, need assembling steam valve to control the circulation of steam, existing steam dredge stream valve due to its structural design unreasonable, in use, easily cause the leakage of steam, make troubles to use.
Summary of the invention
For the problems referred to above, the invention provides a kind of reasonable in design, easy-to-use steam thin stream valve.
The present invention is achieved through the following technical solutions:
Steam dredges stream valve, comprise upper valve body, the lower valve body linked into an integrated entity with upper valve body, at upper valve body, there is discharge route, lower valve body has the inlet passage be communicated with discharge route, conical bearing block is fixedly installed in lower valve body, described inlet passage runs through the upper and lower end face of conical bearing block, and cover the cover body of conical bearing block inlet passage exhaust port, this cover body one end open, the other end is closed, the opening end of described cover body is greater than the minimum dimension of conical bearing block outer surface but is less than outer surface overall dimensions, the sealing block for closed discharge route is provided with in lower valve body, and be arranged on the linkage mechanism making sealing block disengaging discharge route between cover body and sealing block in cover body uphill process.
Have employed such scheme, have steam to enter valve from inlet passage, steam jack-up cover body, and the jack-up of cover body can drivening rod mechanism action, the action of linkage mechanism drives sealing block to depart from discharge route, thus inlet passage is communicated with discharge route, and such steam can discharge valve; And when not having steam to enter, cover body declines and drives sealing block to seal discharge route by linkage mechanism, thus realize the closedown of valve.Structure of the present invention is simple, reasonable in design, can steam be made smoothly to derive, meet the user demand of steaming plant.
Further, described linkage mechanism comprises the first connecting rod that one end is fixedly connected on cover body outer wall, the second connecting rod on sealing block is fixedly connected on one end, and two ends difference one_to_one corresponding is flexibly connected the intermediate connecting rod of first connecting rod, second connecting rod, the middle part of rising intermediate connecting rod is arranged in lower valve body by bearing pin is rotating.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Embodiment:
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, steam dredges stream valve, comprise upper valve body 1, the lower valve body 2 linked into an integrated entity with upper valve body, at upper valve body, there is discharge route 3, lower valve body has the inlet passage 4 be communicated with discharge route, conical bearing block 5 is fixedly installed in lower valve body, inlet passage runs through the upper and lower end face of conical bearing block, and cover the cover body 6 of conical bearing block inlet passage exhaust port, this cover body one end open, the other end is closed, the opening end of cover body is greater than the minimum dimension of conical bearing block outer surface but is less than outer surface overall dimensions, the sealing block 7 for closed discharge route is provided with in lower valve body, and be arranged on the linkage mechanism making sealing block disengaging discharge route between cover body and sealing block in cover body uphill process.Wherein, linkage mechanism comprises the first connecting rod 8 that one end is fixedly connected on cover body outer wall, the second connecting rod 9 on sealing block is fixedly connected on one end, and two ends difference one_to_one corresponding is flexibly connected the intermediate connecting rod 10 of first connecting rod, second connecting rod, the middle part of rising intermediate connecting rod is arranged in lower valve body by bearing pin 11 is rotating.In concrete enforcement, be provided with spring 12 between cover body outer wall and upper valve body, the effect of this spring is when not having steam to enter in valve, impels cover body to descend through linkage mechanism and drives sealing block to cover discharge route, can realize the shutoff of valve like this.In addition, in order to make the steam of discharging from valve have certain buffering, in upper valve body, start there is taper buffer cavity 13.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
