Abstract
The utility model relates to a pivoted antifreeze valve which is the improvement of the structure of the valve of a water supply pipe-line. Because a valve is usually buried underground, the repair of the pipe-line is inconvenient, particularly the inside of the pipe-line which is above the ground stores water, which easily causes the frost crack or the frost damage of the pipe-line. The pivoted antifreeze valve is characterized in that a press cover is provided with a water supply hole and a drain hole, the distance between the water supply hole and the drain hole is 90 DEG, and the drain hole and the water supply hole are deviated from the centre point of a valve core; the pivoted antifreeze valve can control the closing of the underground valve on the ground, which causes the water of the pipe-line on the ground to be drained over and increases the service life of the pipe-line.
Description
The utility model relates to the valving on a kind of water supply pipe, mainly is its structure is improved.
At present, the inside and outside normally used valve of water supply pipe of installation room is to be made of valve body, rotatable handle, spherical valve, via.Can be installed on the face of land or be embedded on the underground water supply pipe, as control valve.Deficiency is to run into water tap or pipeline maintenance, need excavate and be embedded in underground valve, wastes time and energy.Especially water is arranged in cold season in because of the pipeline on the face of land, make the freezing or bursting by freezing of pipeline easily, make tap water stop using inconvenience.
The purpose of this utility model be intended to avoid the deficiency of above-mentioned technology and provide a kind of on ground surface closing of lower valve controllably, and will expose that the water of pipeline drains on the face of land, have the performance of antifreezing valve.
The purpose of this utility model is by reaching to get off: turning to antifreezing valve device is to be made of valve body (1), spool (3), positioning screwn (4), water inlet (10), spilled water hole (11), gland (8), and it is characterized in that: a. has water inlet (10) and spilled water hole (11) on gland (8).B. and two pitch-rows differ 90 °.C. depart from the central point of spool (3) with spilled water hole (11) water inlet (10).
Fig. 1 is for turning to the frost valve topology view.
Fig. 2, Fig. 3 are sectional drawing.
(1) is that valve body, (2.7) are that lock screw, (8) for gland, (9) fastening screw trip bolt, (10) for water inlet, (11) be spilled water hole for positioning screwn, (5) for nylon washer, (6) for spool, (4) for rubber cushion, (3) among the figure.
The utility model will just be done further to comment in conjunction with implementing:
When opening state: the outlet pipe (being rotatable handle) that is connected on manual adjustment and the spool (3) is by turning clockwise 90 °, one side of spool (3) has positioning screwn (4) qualification that chase groove ora terminalis is equipped with on the valve body (1), spool (3), interior via and water inlet (10) conducting on the gland (8), and spilled water hole (1) is sealed by nylon washer (5), and this moment, valve was in running order.
During off status: the outlet pipe (being rotatable handle) that manual adjustment is connected with spool (3) upper end is by being rotated counterclockwise 90 °, one side of spool (3) has positioning screwn (4) qualification that chase groove ora terminalis is equipped with on the valve body (1), spool (3), in via on gland (8) on spilled water hole (1) conducting, valve is fallen with the discharge in the water pipe of top.And water inlet (10) by nylon washer (5) sealing, and this moment, valve was in closed condition (also claiming the sluicing state).
The utility model compared with prior art has installation, uses, and is easy to maintenance, can be embedded in underground valve closing in face of land control, and the water in the pipeline drains on cold season can be with the face of land, has improved the service life of pipeline.
Claims (1)
1, a kind of frost valve that turns to is to be made of valve body (1), spool (3), positioning screwn (4), water inlet (10), spilled water hole (11), gland (8), it is characterized in that:
A. on gland (8), have water inlet (10) and spilled water hole (11);
B. water inlet (10) and spilled water hole (11) are at a distance of 90 °;
C. depart from the central point of spool (3) with spilled water hole (11) water inlet (10).
