Abstract
The utility model relates to a novel air pressure balancing valve in sewer, comprising a bent tube valve cap, a hole plate, a valve body and a valve core that is a seamless ping pong. Proved by calculation, the valve core moves when the interior of a sewer generates 0.25 cm water column negative pressure, and the valve core is driven to reset and be sealed under the action of dead weight after air enters the sewer and the gas pressure is balanced, which ensures that the sealed water in a floor drain can not be carried away. The air pressure balancing valve in sewer can be arranged vertically on the upper end of a vertical sewer, the tail end of a transverse tube or the sewer of the floor drain with the valve port pointing downward.
Description
The utility model relates to a kind of drainage pipeline air pressure balance valve.
At the floor drain of usefulness, general water seal layer is more shallow, when producing big negative pressure in the drainage pipeline, brings the sealing water in the floor drain into drainage pipeline easily, destroys sealing, causes smell effusion in the pipeline.This kind phenomenon, tall building are especially serious.
In order to address the above problem,, but still can not stop to produce in the drainage pipeline negative pressure though present have the water seal of intensification layer floor drain to come out.For using floor drain, then find no any solution.
The purpose of this utility model provides a kind of new drainage pipeline air pressure balance valve, makes drainage pipeline not produce negative pressure, also just can not take away sealing water in the floor drain.
Air pressure balance valve described in the utility model is the gravity type one-way valve that automatically resets, and by bend pipe valve gap (1) orifice plate (2), valve body (3) and spool (4) constitute.Vertically, valve port is installed on the drainage pipeline downwards, when sewer produce negative pressure, when acting on pressure on the spool (4) greater than the gravity of spool (4), promote spool (4) and leave valve port, ambient air enters drainage pipeline through valve port, behind the inside and outside air pressure balance of drainage pipeline, spool (4) resets, seals under self gravitation and manifold pressure effect.Therefore guaranteed that the sealing water in the floor drain is not pulled away.
Because the property of the utility model drainage pipeline air pressure balance valve has determined that its spool (4) must be big by volume, lightweight material constitutes.This valve selects for use seamless table tennis to do spool, table tennis diameter φ 3.8cm, and weight is less than 2.5g, holds the valve port intended diameter φ 3.6cm on the valve body (3) of spool.As calculated, valve port area is greater than 10cm
2, promptly when producing 0.25cm water column negative pressure in the drainage pipeline, the pressure that acts on the spool (4) is enough to make its action.
The utility model novel structure, cheap, simple and practical, install easily.When as long as the sealing water depth is greater than 0.25cm in the floor drain, can guarantees its sealability and do not make smell effusion pipeline in.To especially effective with floor drain.
Description of drawings and embodiment:
(1)---the bend pipe valve gap.(2)---orifice plate.
(3)---valve body.(4)---spool.
The utility model drainage pipeline air pressure balance valve is made of bend pipe valve gap (1) orifice plate (2), valve body (3) and spool (4).Bend pipe valve gap (1) one side straight tube is longer, and there are screw thread, sealing surface and six sides in the lower end, and the valve gap side that is connected with valve body has screw thread and collection chamber; Orifice plate (2) and seal washer are one, have 3 holes, its diameter identical with the bend pipe aperture, and it act as sealed valve cap (1) obstruction valve gap (1) endoporus with valve body (3) junction and when preventing spool (4) action; Valve body (3) holds its internal structure of spool (4) to be convenient to spool (4) and to reset under the self gravitation effect, and valve port diameter is designed to φ 3.6cm, and spool (4) is seamless table tennis, its diameter phi 3.8cm, and weight is less than 2.5g.
This valve is vertical, and valve port is installed in down downwards on water standpipe upper end, following water transverse tube end or the floor drain down-comer.Plane on the water transverse tube under valve port must be higher than, sewage can not enter in the valve body (3) during with assurance work.
Claims (5)
1, drainage pipeline air pressure balance valve is characterized in that by bend pipe valve gap (1), orifice plate (2), valve body (3), reaches spool (4), constitutes.
2, according to claim 1 described drainage pipeline air pressure balance valve, it is characterized in that bend pipe valve gap (1) one side straight length is longer, the screw thread that its lower end has screw thread, sealing surface and six sides, valve gap collection chamber to be arranged and link with valve body (3).
3, according to claim 1 described drainage pipeline air pressure balance valve, it is characterized in that the hole utmost point (2) and seal washer are one, hole count is 3 holes, its diameter equals the bend pipe internal diameter.
4, according to claim 1 described drainage pipeline air pressure balance valve, it is characterized in that valve body (3) internal structure is convenient to spool (4) and resets under self gravitation, valve port diameter φ 3.6cm, straight burr is arranged at the cylindrical bottom.
5, according to claim 1 described drainage pipeline air pressure balance valve, it is characterized in that selecting for use seamless table tennis to do spool (4), table tennis diameter φ 3.8cm, weight is less than 2.5g.
