Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of dead angle-free thermal static force trap, in particular to a kind of dead angle-free thermal static force trap used in pharmaceutical industry steam pipeline, steam drainage is carried out. BACKGROUND
[0002] The trap on the market currently, structure is more complex, there is sanitary dead angle, not applicable to the application of pharmaceutical industry. SUMMARY
[0003] The utility model aims at overcoming the problem of sanitary dead angle, designs a kind of dead angle-free thermal static force trap.
[0004] In order to realize the above-mentioned purpose, the technical scheme of the utility model is:
[0005] Upper cover, valve seat, clamp, screen baffle, spring, temperature-sensitive capsule, sealing washer are composed;Valve seat is equipped with installation recess and drain in the inside, temperature-sensitive capsule is installed in recess, spring is installed on temperature-sensitive capsule, upper cover and valve seat are sealed with sealing washer in the middle, and clamp is used to compress it tightly.
[0006] The main material of temperature-sensitive capsule is sensitive thermal strain material, and ball is connected to tail part.
[0007] The bottom plane of the installation groove in the inside of valve seat is equipped with certain slope, to facilitate emptying.
[0008] The sealing washer is high-temperature-resistant flexible material.
[0009] Upper cover, valve seat, clamp, screen baffle, spring, temperature-sensitive capsule are stainless steel material. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is structure schematic view of a kind of dead angle-free thermal static force trap of the utility model;
[0011] Figure 2 It is temperature-sensitive capsule structure schematic view of the utility model.
[0012] In the drawing: 1, upper cover;2, clamp;3, screen baffle;4, spring;5, temperature-sensitive capsule;6, valve seat;7, sealing washer;8, drain;9 ball. DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the utility model will be described clearly and completely in the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0014] Embodiment 1:
[0015] Please refer to Figure 1 The utility model provides a kind of technical scheme of dead angle-free thermal static force drain valve: install temperature-sensitive capsule on valve seat, there is circular drain hole in valve seat inside, size is matched with spherical bead below temperature-sensitive capsule, and drain hole can be sealed when bead is pressed down;Spring is installed above temperature-sensitive capsule, spring is in compression state when normally installed, and temperature-sensitive capsule is compressed tightly;Screening net partition is installed above spring;Sealing washer is installed between upper cover and valve seat, and is sealed by clamping hoop;When steam enters valve, temperature-sensitive capsule is heated and closes drain hole, prevents steam passing through valve.When condensate enters valve, temperature-sensitive capsule is cooled and opens drain hole, and drain valve starts to discharge condensate.
