Abstract
Memory alloy spring drain valve relates to a kind of Automatic steam trap Trap with memory alloy spring be arranged in vapour system.Mainly short for working life for solving existing drain valve, complex structure and other problems designs.It comprises valve body, valve body has be connected import, outlet, valve pocket; Filter screen is located at the inner of import, and there is front pad in the outside of filter screen, and there is front gland nut in the outside of front pad, and the screw-thread fit on front gland nut and import inwall, front pad and front gland nut have opening; Valve seat is located at the inner of outlet, has rear pad outside valve seat, and there is rear gland nut in the outside of rear pad, and the screw-thread fit on rear gland nut and outlet inside wall, valve seat and rear pad have opening; Spool and valve rod are fixed, and valve rod is positioned at valve pocket after passing through from valve seat opening, and removable insole pieces is sleeved on valve rod, and valve rod has nut, and on the valve rod between removable insole pieces and valve seat, cover has memory alloy spring.Advantage is long service life, and structure is simple.
Description
Technical field:
The utility model relates to drain valve, specifically relates to a kind of Automatic steam trap Trap with memory alloy spring be arranged in vapour system.
Background technique:
The effect being arranged on the drain valve in vapour system is discharged as early as possible at the water of condensation in vapour system, automatically prevents the leakage of steam to greatest extent simultaneously.
The most energy-conservation in the drain valve of current application is wax drain valve, and its working principle is the wax core in it when running into the steam of high-temperature, becomes liquid state, is ejected by spool, valve closing from solid-state; When wax core runs into the low water of condensation of temperature, it is then become solid-state from liquid state, and under the effect of bias spring, spool is regained, valve open.Its deficiency is: wax core can only to-and-fro motion about 50,000 times, and working life is short, and it also exists complex structure and other problems in addition.
Summary of the invention:
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the memory alloy spring drain valve of long service life.
Above-mentioned purpose is achieved in that it comprises valve body, the front end of valve body is import, the rear end of valve body is outlet, valve pocket in valve body between import and outlet, valve pocket and import, export and be connected, described import is identical with the internal diameter of outlet, and the internal diameter of import and outlet is all greater than the internal diameter of valve pocket, the inwall of valve body import and outlet has screw thread, and described screw thread is for being connected with vapour system pipeline;
Also comprise filter screen, filter screen is located at the inner of import, there is front pad in the outside of filter screen, there is front gland nut in the outside of front pad, screw-thread fit on front gland nut and import inwall, front gland nut can make filter screen be close to the inner of import after tightening, and described front pad and front gland nut are all provided with opening;
Also comprise valve seat, valve seat is located at the inner of outlet, has rear pad outside valve seat, there is rear gland nut in the outside of rear pad, screw-thread fit on rear gland nut and outlet inside wall, rear gland nut can make valve seat be close to the inner of outlet after tightening, and described valve seat and rear pad are all provided with opening;
Spool and valve rod are fixed, spool is located at the outside of valve seat opening, valve rod is positioned at valve pocket after passing through from valve seat opening, also comprise removable insole pieces, removable insole pieces is sleeved on valve rod, is positioned on the valve rod outside removable insole pieces and has nut, on valve rod between removable insole pieces and valve seat, cover has memory alloy spring, memory alloy spring one end withstands in removable insole pieces, and the other end of memory alloy spring withstands on valve seat, leaves gap between removable insole pieces and valve pocket inwall.
The utility model has the advantages that: during work, when the water of condensation that temperature of coming in from valve body import is lower, water of condensation promotes valve rod and spool moves to outlet end, now memory alloy spring compression, valve open; When the water of condensation that temperature of coming in from valve body import is high, memory alloy spring resets, and band ovable valve stem and spool move to entrance point, valve closing.The elasticity of its memory alloy spring is adjustable, and easy to adjust, memory alloy spring reciprocable 2,000,000 times, thus improves the working life of drain valve, and its structure is simple in addition, produces easily, is suitable for applying.
Accompanying drawing illustrates:
Accompanying drawing is structural representation of the present utility model.
Embodiment:
With reference to accompanying drawing, it comprises valve body 1, the front end of valve body is import 13, the rear end of valve body is outlet 14, is valve pocket 15 in the valve body between import and outlet, valve pocket and import, exports and is connected, described import is identical with the internal diameter of outlet, the internal diameter of import and outlet is all greater than the internal diameter of valve pocket, the inwall of import and outlet has screw thread 16, and described screw thread is for being connected with vapour system pipeline;
Also comprise filter screen 6, filter screen is located at the inner of import, there is front pad 7 in the outside of filter screen, there is front gland nut 8 in the outside of front pad, screw-thread fit on front gland nut and import inwall, front gland nut can make filter screen be close to the inner of import after tightening, and described front pad and front gland nut are all provided with opening;
Also comprise valve seat 4, valve seat is located at the inner of outlet, rear pad 3 is had outside valve seat, there is rear gland nut 2 in the outside of rear pad, screw-thread fit on rear gland nut and outlet inside wall, rear gland nut can make valve seat be close to the inner of outlet after tightening, and described valve seat and rear pad are all provided with opening;
Spool 12 and valve rod 9 are fixed, spool is located at the outside of valve seat opening, valve rod is positioned at valve pocket after passing through from valve seat opening, also comprise removable insole pieces 5, removable insole pieces is sleeved on valve rod, is positioned on the valve rod outside removable insole pieces and has nut 10, on valve rod between removable insole pieces and valve seat, cover has memory alloy spring 11, memory alloy spring one end withstands in removable insole pieces, and the other end of memory alloy spring withstands on valve seat, leaves gap between removable insole pieces and valve pocket inwall.
