Abstract
The utility model provides a negative pressure air cooler air isolating valve. At the internal disk seat of releasing that is equipped with of bleeder valve, take sealed base of circular recess and seal gasket with taking circular bellied adjusting nut and fastening screw to alternate to install through lock nut in that the bleeder valve is internal, be equipped with the support frame in the valve body lower part one side of releasing, crank arm and install on the support frame through the round pin axle, the one end of cranking arm and fastening screw sub -unit connection, the other end is connected with the counter weight handle. The utility model discloses it is sealed effectual, simple structure, simple to operate. It is suitable applied as negative pressure air cooler air isolating valve.
Description
Technical field
The utility model relates to the negative pressure air cooler air isolation valve of all size, is specially adapted to the air cooler that negative pressure is lower.
Background technology
The direction of negative pressure air cooler circulation of air is divided into two parts, portion of air flows to blower fan through air cooler, another part air is released in pipeline upstream to blower fan from solidifying water, and air should end to the air of blower fan from the solidifying water upstream in pipeline of releasing in actual use. If air is released and uply in pipeline is failed cut-off from solidifying water, cause solidifying water that air cooler produces to release from the solidifying water pipeline of releasing, easily cause air cooler that solidifying water occurs and leak, must have a kind of valve at air cooler initial operating stage, block fast up air, make water back bending fill fast water. Magneto that sell in market, floatage-type, spring force formula valve use under the environment that has for a long time water, find that valve switch is dumb, and air-isolation ability is not good.
Summary of the invention
The technical problems to be solved in the utility model is that in cut-off negative pressure air cooler condensate line, air is up, makes solidifyingly go under water and fill water back bending. A kind of good sealing effect, negative pressure air isolating valve simple in structure, easy for installation are provided.
The scheme that the utility model technical solution problem adopts is:
In valve body, be provided with the valve seat of releasing releasing, be with circular groove sealed base and gasket seal releasing in valve body to intert to be provided with fastening screw by locking nut and the adjusting nut with circular protrusions, releasing, valve body lower portion one side is provided with bracing frame, crank arm and be arranged on bracing frame by bearing pin, the one end of cranking arm is connected with fastening screw bottom, and the other end is connected with counterweight handle.
Good effect, the utility model good sealing effect, simple in structure, easy for installation. Suitablely apply as negative pressure air cooler air isolation valve.
Brief description of the drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model band circular groove sealed base schematic diagram
Fig. 3 is the adjusting nut schematic diagram of the utility model band circular protrusions
In figure, the valve body of 1. releasing, the valve seat of 2. releasing, 3. locking nut, 4. gasket seal, 5. band circular groove sealed base, 6. the adjusting nut with circular protrusions, 7. cranks arm, 8. bracing frame, 9. bearing pin, 10. counterweight handle.
Detailed description of the invention
According to the figure, in valve body 1, be provided with the valve seat 2 of releasing releasing, intert band circular groove sealed base 5 and gasket seal 4 are installed with fastening screw by locking nut 3 and the adjusting nut with circular protrusions 6 releasing in valve body, releasing, valve body lower portion one side is provided with bracing frame 8, crank arm and 7 be arranged on bracing frame by bearing pin 9, the one end of cranking arm is connected with fastening screw bottom, and the other end is connected with counterweight handle 10.
Design feature of the present utility model and the course of work:
When up when air cooler air is released pipeline from solidifying water in, the solidifying water that air cooler produces cannot be released from the solidifying water pipeline of releasing, now press down by counterweight handle, pull fastening screw by cranking arm, fastening screw drives band circular groove sealed base and gasket seal to move up, valve body passage, and upflowing air is blocked, solidifying water is released because Action of Gravity Field is opened gasket seal, realizes closing of sluicing path.
The fastening screw on counterweight handle top with link together with the adjusting nut of circular protrusions, with circular groove sealed base with combine and form automatic guide with the adjusting nut of semi-circular projection, make gasket seal combined integrated with band circular groove sealed base by locking nut.
Counterweight handle is exerted pressure by cranking arm, and make to release valve seat seal and gasket seal are tightr.
In negative pressure air cooler when operation,, negative pressure air intercepts valve and closes, and the air up by condensate line is cut off, and air cooler produces solidifying water by cold and hot exchange, coagulates to exercise that watertight is curved produces water seal at short notice fast under water.
