Abstract

The utility model relates to bimetal temperature regulating steam trap, which is suitable for the fields of oilfield, chemical industry, textile, food processing, and steam heating systems, can automatically discharge condensation water and air in pipelines, and can effectively prevent the leakage of fresh steam. In the utility model, a valve seat is arranged between an outlet and an inlet of a T-shaped three-way valve, the valve seat is provided with a valve core and a core sleeve, the upper end of a core shaft extends into a regulating bolt, and the regulating bolt acts on a bimetal assembled group; the regulating bolt is provided with a regulating nut and a valve cap; because a sensing body on the core shaft is the bimetal assembled group which is changed following the change of temperature, a spring can be extended and shrunk, and the condensation water can be discharged outside. The utility model has the advantages that the temperature can be regulated, and the energy-saving effect is obvious.

Description

But bimetal Temp. adjustable type Automatic steam trap Trap

The utility model is a kind of oil, chemical textile, food processing and steam heating system of being applicable to, can get rid of condensed water and air in the pipeline automatically, stops the device of steam leakage effectively, but particularly a kind of bimetal Temp. adjustable type Automatic steam trap Trap.

The existing drain valve that is applied in the steam pipe network mainly contains thermomotive and mechanical-type, exist leaked steam, noise greatly, not shock-resistant, shortcoming such as the life-span is short, and exhaust temperature can not adjust, and can not fully effectively utilize heat energy.

The utility model purpose is that design a kind ofly can fully effectively utilize steam heat, improve pipe network operation efficient, and this is to the drain valve of energy-conservation purpose.

Structure of the present utility model is: but a kind of two gold is taken charge of the Temp. adjustable type Automatic steam trap Trap, has a valve body (1) that is inverted T-shaped, two opposite ends, valve body (1) bottom are respectively entrance and exit, in the cavity in the middle of valve body (1) bottom inlet and outlet valve seat (2) is housed, core retainer plate (4) is housed on the valve seat (2), spool (3), core retainer plate (4) is contained in mandrel (6) underpart, temperature sensor (7) is enclosed within mandrel (6) and goes up and spring (5) is pressed on the valve body (1), mandrel (6) upper end portion places transfers in the bolt (10), filter screen (8) is on valve body (1) internal surface, valve gap (9) is contained in valve body (1) upper end, transferring bolt (10) to pass valve gap (9) lower end withstands on the temperature sensor (7), transfer female (11) to be contained in and transfer on the bolt (10), bonnet (12) is contained in to be transferred on female (11), temperature sensor (7) is rondelle bimetallic strip combination group (13), and promptly relative two of the one side that rondelle bimetal expansion coefficient is low is one group, and another group is serially connected in mandrel (6) and goes up rondelle bimetal group of formation.

The utility model has the advantages that: (1) owing to adopt dull and stereotyped temperature sensor, impact resistance is strong, and serviceability is good.(2) no operating noise, the favorable environment protection.(3) can reach the purpose of adjusting exhaust temperature by regulating the bolt elasticity, to adapt to the different temperatures occasion.(4) have condensed water in high temperature to store in the valve, form water seal, no fresh steam leaks, and energy-saving benefit 〉=30% leaks vapour rate＜3%.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the used temperature sensor schematic representation of the utility model.

Embodiment: specific embodiment structure of the utility model as shown in Figure 1.Valve body 1 is a three-port structure, its underpart two corresponding ports are outlet and inlet, its upper opening valve gap 9 that spins, spin bonnet 12 and inside, outside, valve gap 9 upper end spins and transfers female 11, transfer to be connected with again on female 11 and transfer bolt 10, valve body is equipped with valve seat 2 between 1 gateway, spool 3 is positioned at valve seat 2 tops and core retainer plate 4 is housed, core retainer plate 4 is contained in mandrel 6 lower ends and mandrel 6 upper ends are positioned at accent bolt 10 lower end cavitys, the circular plate type bimetal temperature sensor 7 that adopts the bimetal group mode of closing to form is fixed on the mandrel 6, and spring 5 is in temperature sensor 7 bottoms and place on the valve body 1.The utility model working principle is: relative two of the one side that the bimetallic expansion coefficient of rondelle is low is one group, many groups constitute a flow rate circular plate dual metal group, each unit bimetal rises with temperature, extend vertically towards the one side that expansion coefficient is low, begin again after temperature reduces to shrink, recover flattened state.With the mandrel of opening/shutting valve, the axle as the bimetal group makes bimetal overcome the elastic force throttle down of spring in high temperature deformation when extending axially, when temperature descends, when being reduced to the water of condensation setting temperature, bimetal bending deflection reduces, and the hotwork of generation firmly also reduces.Bimetallism power reaches because intake-outlet presses layer to act on when 5 pressure sums are less than spring force on the valve, and spool is held up by spring, with the low-temperature condensate discharging, so moves in circles and finishes hydrophobic function.When need regulating temperature, unload bonnet, unscrew jack panel, will adjust the accent bolt with the screw-driver basis again, adjust to and require to tighten jam nut after the temperature, refill bonnet with spanner.

Claims

1, but a kind of bimetal Temp. adjustable type Automatic steam trap Trap, has a valve body (1) that is inverted T shape, two opposite ends, valve body (1) bottom are respectively entrance and exit, it is characterized in that in the cavity in the middle of valve body (1) bottom inlet and outlet valve seat (2) being housed, core retainer plate (4) is equipped with on valve seat (2) top, spool (3), core retainer plate (4) is contained in mandrel (6) underpart, temperature sensor (7) is enclosed within mandrel (6) and goes up and spring (5) is pressed on the valve body (1), mandrel (6) upper end portion places transfers in the bolt (10), filter screen (8) is on valve body (1) internal surface, valve gap (9) is contained in valve body (1) upper end, transferring bolt (10) to pass valve gap (9) lower end withstands on the temperature sensor (7), transfer female (11) to be contained in and transfer on the bolt (10), bonnet (12) is contained in to be transferred on female (11).
