Abstract
The utility model provides a waterproof air release valve, the structure of which comprises: the valve comprises a valve seat, a hand wheel, a set screw, a waterproof breathable film and a plug screw; fixing a hand wheel in a hole on a valve rod through a set screw, screwing the valve rod in an internal thread of a valve seat, placing a waterproof breathable film in the hole at the front end of the valve seat, and then fastening the waterproof breathable film by using a screw plug; in order to realize the functions of water prevention and air exhaust, the utility model adopts conical surface sealing, wherein the valve seat is an end surface, and the valve rod is of an angular conical surface structure. The waterproof air release valve provided by the utility model can be horizontally and vertically installed, and meanwhile, the tightness of the air release valve can be ensured, so that gas in a pipeline system is exhausted, and liquid in the pipeline is left in the pipeline.
Description
Technical Field
The utility model belongs to the technical field of air release valves, and particularly relates to a waterproof air release valve for a gas hand pump.
Background
In order to solve the problem that when the air release valve releases air, liquid in a pipeline can be discharged along with air flow under the action of pressure, the liquid in the pipeline can possibly pollute the environment, meanwhile, the sealing of the air release valve fails, the pressure of the whole pipeline system is damaged, and the system cannot work normally. The existing air release valves are almost all for liquid, the air release valves are not waterproof or waterproof filtering parts are specially added in pipelines, so that the whole system becomes complex and is not beneficial to processing and maintenance.
SUMMERY OF THE UTILITY MODEL
In view of the above situations and requirements, an object of the present invention is to provide a waterproof air release valve which is convenient, fast and reliable to use, and which can prevent water inside a pipeline from flowing out, prevent dust outside the pipeline from entering the pipeline, and achieve the functions of dust isolation, water prevention and ventilation.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a waterproof relief valve, its structure includes: the valve comprises a valve seat, a hand wheel, a set screw, a waterproof breathable film and a plug screw; the inner and outer cylinders at one end of the valve seat are provided with tapered threads, the other end of the valve seat is of an outer hexagonal structure, and the inner side of the outer hexagonal structure is provided with a stepped hole with internal threads; the side surface of the valve seat, which is close to the outer hexagonal structure, is provided with a vent hole, and the air can be discharged through the vent hole and the air discharging speed can be reduced; the outer taper thread structure of plug screw terminal surface fluting, middle through-hole compresses tightly waterproof ventilated membrane in the disk seat through the plug screw, separates dirt waterproof ventilation through waterproof ventilated membrane.
The hand wheel is provided with a threaded hole in the circumferential direction.
The front section of the valve rod is of a conical surface structure with an angle, the middle of the valve rod is provided with an external thread which is matched with an internal thread of a hexagonal structure outside the valve seat, and the side surface of the tail of the valve rod is provided with a hole for installing a set screw.
According to the utility model, the hand wheel is fixed in the hole on the valve rod through the set screw, the valve rod is screwed in the internal thread of the valve seat, the waterproof breathable film is placed in the hole at the front end of the valve seat, and then the waterproof breathable film is fastened by the screw plug; in order to realize the functions of water prevention and air exhaust, the utility model adopts conical surface sealing, wherein the valve seat is an end surface, and the valve rod is of an angular conical surface structure.
The utility model has the beneficial effects that: the waterproof air release valve can be horizontally and vertically installed, and meanwhile, the tightness of the air release valve can be ensured, so that gas in a pipeline system is exhausted, and liquid in the pipeline is left in the pipeline.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a valve seat;
FIG. 3 is a schematic view of the structure of the air release valve when the air release valve is in air release operation;
in the figure: 1. a plug screw; 2. a waterproof breathable film; 3. a valve stem; 4. a valve seat; 5. tightening the screw; 6. a handwheel.
The specific implementation mode is as follows:
the present invention will be described below by way of example, and as shown in fig. 1 and 2, the present invention provides a waterproof vent valve in which a waterproof breathable film 2 is mounted in a hole of a valve seat 4, and is tightly pressed and sealed by a plug screw 1, a hand wheel 6 is fixed to a valve stem 3 by a set screw 5, and the valve stem 3 is screwed into a threaded hole of the valve seat 4, and at this time, the head of the valve stem 3 and the central hole of the valve seat 4 are sealed by a tapered surface at the tip of the valve stem 3 and the hole end surface of the valve seat 4.
During actual sealing work, the structural state is as shown in fig. 1, the whole waterproof air release valve is installed in a pipeline structure needing air release, the hand wheel 6 is rotated, the valve rod 3 moves forward to the front end of the valve seat 4 through the thread matched with the valve rod in the valve seat 4 until the valve rod is screwed, the air release valve is in a sealing state at the moment, and the air release hole in the valve seat 4 is closed.
During actual deflation, the structural state is as shown in fig. 3, the hand wheel 6 is rotated, the valve rod 3 moves in the valve seat 4 in the direction of the arrow shown in fig. 3, the gas in the pipeline passes through the central hole of the screw plug 1 in the direction of the arrow and then passes through the waterproof breathable film 5, the water vapor in the gas flow is blocked by the waterproof breathable film 5, and the gas flow is discharged through the vent hole on the valve seat 4. After the gas in the pipeline is exhausted, the hand wheel 6 is rotated according to the sealing working state of the figure 3, so that the air release valve is in the sealing working state.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
