Abstract
A kind of ammonia valve flap, belongs to art of refrigeration units, comprises valve petal body, Sealing; Described valve petal body comprises flap dish, flap handle; Described flap dish is cylindrical plate-like fabricated metals, and flap dish upper center is provided with flap handle, and flap dish lower end surface is provided with Sealing mounting groove, and described mounting groove is annular groove; Described flap handle is cylindrical, is arranged on concentric with flap dish above flap dish and vertical with two end faces of flap dish; Described Sealing is the annular that teflon is made, and its width mates with the mounting groove on flap dish, and its thickness is more than or equal to the degree of depth of mounting groove, has and can realize reliable sealing, and processing technology is simple, is convenient to the feature of local replacing hermetic unit.
Description
Technical field
The utility model belongs to art of refrigeration units, particularly a kind of ammonia valve flap.
Background technique
Ammonia valve, it is a kind of assembly conventional in chiller plant, its effect is that conventional ammonia valve comprises valve body mostly, import in refrigeration systems to the flowing or the blocking-up that control refrigeration agent in the using process of refrigeration agent by closing and open ammonia valve, import adpting flange, outlet, outlet adpting flange, flap, handle, end cap; Import adpting flange is connected with the input pipeline of refrigeration agent, refrigeration agent enters ammonia valve by input pipeline, by the gap of flap and outlet, enter outlet, outlet adpting flange is connected with refrigeration agent output pipeline, refrigeration agent enters output pipeline after ammonia valve, completes conveying or the circulation of normal refrigeration agent; When needs block conveying or circulation, turn handle, make to close between flap and outlet, refrigeration agent is just blocked by flap and can not export from outlet; And when valve blocks refrigeration agent, not allowed leakage, this just proposes certain requirement to the sealing between flap and outlet; Existing flap is adopt metal to make mostly, in order to ensure itself and the sealing exported, the contact segment of flap and outlet sinters one deck alloy, increases its wear resistance and sealing, due to the proprietary attribute of metal, when its surface of contact can not be fitted completely, its sealability just reduces greatly, and sintering process can affect the distortion of whole flap simultaneously, and complex process, cost is high, not easily realizes local replacing.
Summary of the invention
For existing ammonia valve flap Problems existing, the utility model proposes a kind of ammonia valve flap; It is characterized in that: comprise valve petal body, Sealing; Described valve petal body comprises flap dish, flap handle; Described flap dish is cylindrical plate-like fabricated metals, and flap dish upper center is provided with flap handle, and flap dish lower end surface is provided with Sealing mounting groove, and described mounting groove is annular groove; Described annular groove bottom width is greater than oral area width; Described flap handle is cylindrical, is arranged on concentric with flap dish above flap dish and vertical with two end faces of flap dish; Described Sealing is the annular that teflon is made, and its width mates with the mounting groove on flap dish, and its thickness is more than or equal to the degree of depth of mounting groove; Described Sealing with contact an end face cross-sectional width bottom mounting groove and be greater than other end width.
Beneficial effect
The beneficial effects of the utility model are, can realize reliable sealing, and processing technology is simple, is convenient to local replacing hermetic unit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. flap handle, 2. flap dish, 3. mounting groove, 4. Sealing.
Embodiment
In order to further illustrate the technical solution of the utility model, now further illustrating embodiment of the present utility model by reference to the accompanying drawings, as Fig. 1, selecting the material of valve petal body to be steel; Diameter 20 mm length selecting flap handle 1 is 60 millimeters, and select the diameter of flap dish 2 to be 100 millimeters, thickness is 20 millimeters; The upper-end surface of flap handle 1 is vertical and flap dish 2 is also concentric with flap dish 2; In the lower end surface of flap dish 2, process interior circular diameter 60 millimeters, outside diameter 84 millimeters and with the concentric circular groove of flap dish 2 as mounting groove 3, the degree of depth of mounting groove 3 12 millimeters, there is outward-dipping angle the two side of its circular groove, be 1 degree with the angle of the lower end surface of flap dish 2, ensure that the bottom width of circular groove is slightly larger than oral area width like this; Select polytetrafluoroethylmaterial material to make interior circular diameter 60 millimeters, outside diameter 84 millimeters, thickness is that the annular of 12.5 millimeters is as Sealing 4; The dual-side of Sealing 4 is kept identical with the gradient of mounting groove 3; During use, Sealing 4 is fitted in the mounting groove on flap dish 2, just completes enforcement of the present utility model; Because Sealing 4 is made up of teflon, there is certain elasticity, under pressure, can ensure to contact with the exit portion on valve body closely, thus ensure that its sealability, and there is corrosion resistance, work under being applicable to refrigerant environment; Meanwhile, when Sealing 4 is worn or other damage, can takes off easily, press new Sealing 4, just can continue normal use, and unnecessaryly abandon whole flap.
