Description

Loose float trap with cleaning function

Technical field

The utility model is related to valve field, especially a kind of loose float trap with cleaning function.

Background technology

Loose float trap is relatively advanced at present, designs one of most rational drain valve, its structure is simple, interior Portion is only both float and opening and closing element there are one the stainless steel hollow float of movable part fine gtinding, and no quick-wear part uses Service life is very long.The steam that loose float trap is widely used in the industrial departments such as oil, chemical industry, light industry, metallurgy, electric power adds It is automatic to exclude condensed water and steam is prevented to leak in hot equipment and steam pipe line, heating equipment and steam pipe line water hammer can be prevented The generation of phenomenon, it is ensured that its equipment and pipeline are run under optimum condition.The valve or energy-conserving product, to improve heating system and The thermal efficiency of equipment saves the energy and plays an important role.

As shown in Figure 1, existing loose float trap includes valve body 1, spool 7 and filter screen are provided in valve body 1 4, water inlet 5 and water outlet 6 are provided on valve body 1, and air bleeder valve 8, first chamber 2 and the second chamber are additionally provided in valve body 1 Room 3.For current compressed air reservoir using free floating ball type automatic steam trap, it is empty that automatic steam trap should be automatically drained out compression Condensed water in gas ensures that compressed air quality meets the requirement of subsequent user.But it because compressed air reservoir is carbon steel material, deposits In corrosion problem.The impurity of tank inside corrosion is entering automatic steam trap with condensed water, and condensed water is by strainer 4 from water outlet 6 discharges, and on the filter screen 4 that impurity is then accumulated, automatic steam trap filter screen 4 can be caused to be blocked as impurity is cumulative, Blocked drain influences compressed air quality.For the problem that automatic steam trap strainer is blocked, need start and stop equipment then to certainly Dynamic drain valve is repaired or replaced, and this reduces production efficiencys, improve production cost.

Utility model content

The utility model is to solve automatic steam trap blocking and difficult cleaning of technical problem to be to provide a kind of band cleaning work( The loose float trap of energy.

Technical solution used by the utility model is：Loose float trap with cleaning function, including valve body, valve It is provided with first chamber in vivo, second chamber is provided with below first chamber, first chamber is connected by filter screen and second chamber It connects, the water outlet that the water inlet being connected to first chamber is provided on valve body and is connected to second chamber, setting in second chamber There is the spool using buoyancy automatic shutter water outlet, is additionally provided with air bleeder valve in valve body, further includes being arranged on valve body Cleaning structure, the cleaning structure include that the Butterworth Hatch being connected to second chamber is arranged on valve body and is connected to first chamber Corresponding valve is provided on sewage draining exit, Butterworth Hatch and sewage draining exit.Compressed air is entered by Butterworth Hatch in valve body, by filter screen On impurity by sewage draining exit exits valve body, the impurity in valve body can be cleaned by cleaning structure, solves and freely float The problem of ball-type drain valve blocks, improves compressed air quality, reduces the frequency of equipment repair and maintenance, while avoiding and tearing open The workload that dress valve body is brought.

The utility model has the beneficial effects that：The loose float trap with cleaning function of the utility model, passes through Cleaning structure can clean the impurity in valve body, solve the problems, such as loose float trap blocking, improve compression Air quality, reduces the frequency of equipment repair and maintenance, while avoiding the workload that dismounting valve body is brought.

Specific implementation mode

The utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in Fig. 2, the loose float trap with cleaning function of the utility model, including valve body 1, in valve body 1 It is provided with first chamber 2,2 lower section of first chamber is provided with second chamber 3, and first chamber 2 passes through filter screen 4 and second chamber 3 It connects, the water inlet 5 being connected to first chamber 2 and the water outlet being connected to second chamber 36, second chamber is provided on valve body 1 It is provided with the spool 7 using buoyancy automatic shutter water outlet 6 in 3, air bleeder valve 8 is additionally provided in valve body 1, further includes setting Cleaning structure on valve body 1, the cleaning structure include be arranged the Butterworth Hatch 9 being connected to second chamber 3 on valve body 1 and with The sewage draining exit 10 that first chamber 2 is connected to is provided with corresponding valve on Butterworth Hatch 9 and sewage draining exit 10.

In use, Butterworth Hatch 9 and sewage draining exit 10 are closed, the water inlet 5 that the condensed water in compressed air reservoir passes through valve body 1 Into valve body 1, through filter screen 4 and by 6 exits valve body 1 of water outlet, air bleeder valve 8 can prevent compressed air to be discharged valve body 1.When 1 impeded drainage of valve body is cleaned, water inlet 5 is closed, spool 7 closes water outlet 6, opens Butterworth Hatch 9 and row Dirty mouth 10 is passed through compressed air into valve body 1 by Butterworth Hatch 9, and the impurity on filter screen 4 can be passed through sewage draining exit by compressed air In 10 exits valve body, cleaning process is completed with this.
