Abstract

The utility model provides a but check valve of blowdown, including valve body, rubber coating disk seat, valve plate, adjustment pad, spring, valve rod, sealed pad, holding screw, outlet, blowoff valve. The method is characterized in that: the inner cavity of the valve body is completely vulcanized to form a rubber-coated valve seat, the valve plate is arranged in the center of the inner part of the rubber-coated valve seat and is fixed by the valve rod, the valve rod is provided with a spring for resetting the valve plate and an adjusting pad for preventing the valve plate from sliding along the axial direction, in addition, the valve rod is arranged in the axial hole of the valve body, two ends of the valve rod are fixed by the fastening screws, a rubber sealing pad for sealing is also arranged between the fastening screws and the valve rod, the bottom of the check valve, which is close to the rubber-coated valve seat, is provided with a water outlet, the channel of the water outlet is completely vulcanized rubber, and the blow-down valve is arranged on the water outlet. The utility model has the advantages that: simple structure, convenient operation can in time discharge pipeline hydrops, prevents that the hydrops from freezing in the valve body, makes the valve can normal use in low temperature, cold areas, has more avoided valve body, pipeline to be frost crack.

Description

Check valve capable of discharging sewage

Technical Field

The utility model relates to the valve field, concretely relates to check valve field.

Background

The check valve belongs to the automatic valve class, is a valve which can be opened and closed only by the acting force of the check valve and a medium without driving, and plays a role in preventing the medium from flowing backwards in a pipeline. The check valves are mostly installed in vertical pipes, with the valve plate open upwards, after which the medium flows upwards. When one opening and closing is performed, xu Jiye is created in the tubing above the check valve. In partially cold outdoor areas, the accumulated liquid can freeze to cause the valve plate not to be opened, thereby causing the valve not to be normally used and even causing the valve body and the pipeline to be frost-cracked.

SUMMERY OF THE UTILITY MODEL

For solving the problem that current check valve exists, the utility model discloses a but check valve of blowdown, hydrops in can in time the discharge line prevents that the hydrops from freezing in the valve body, makes the valve can normal use in low temperature, cold area, has more avoided valve body, pipeline to be frost crack.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a check valve capable of discharging sewage comprises a valve body, a rubber-coated valve seat, a valve plate, an adjusting pad, a spring, a valve rod, a sealing pad, a set screw, a water outlet and a sewage valve. The method is characterized in that: the inner cavity of the valve body is completely vulcanized to form a rubber-coated valve seat, the valve plate is arranged in the center of the inner part of the rubber-coated valve seat and is fixed by the valve rod, the valve rod is provided with a spring for resetting the valve plate and an adjusting pad for preventing the valve plate from sliding along the axial direction, in addition, the valve rod is arranged in an axial hole of the valve body, the two ends of the valve rod are fixed by set screws, a rubber sealing pad for sealing is also arranged between the set screws and the valve rod, a water outlet is arranged at the bottom of the check valve close to the rubber-coated valve seat, the channel of the water outlet is completely vulcanized rubber, and the sewage valve is arranged on the water outlet.

The utility model has the advantages that: simple structure, convenient operation can in time discharge pipeline hydrops, prevents that the valve internal hydrops from freezing, makes the valve can normal use in low temperature, cold areas, has more avoided valve body, pipeline by the frost crack.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, each sequence number represents a name: 1. the valve comprises a valve body 2, a rubber-coated valve seat 3, a valve plate 4, an adjusting pad 5, a spring 6, a valve rod 7, a sealing pad 8, a set screw 9, a water outlet 10 and a blow-down valve.

Detailed Description

In order to make the purpose and technical solution of the present invention more clear, the present invention will be further described with reference to the accompanying drawings.

A check valve capable of discharging sewage comprises a valve body 1, a rubber-coated valve seat 2, a valve plate 3, an adjusting pad 4, a spring 5, a valve rod 6, a sealing pad 7, a set screw 8, a water outlet 9 and a sewage valve 10. The method is characterized in that: all vulcanize the formation rubber coating disk seat 2 in 1 inner chamber of valve body, valve plate 3 is installed in the inside centre position of rubber coating disk seat 2 and is fixed by valve rod 6, be equipped with on valve rod 6 and be used for the spring 5 that valve plate 3 reset and prevent that valve plate 3 from following the adjusting pad 4 of endwise slip, valve rod 6 is adorned in the shaft hole of valve body 1 in addition, both ends are fixed by holding screw 8, still be equipped with between holding screw 8 and valve rod 6 and be used for sealed rubber packing 7, the department has seted up outlet 9 near rubber coating disk seat 2 in the bottom of check valve 1, outlet 9 passageway all vulcanizes rubber, blowoff valve 10 is installed on outlet 9.

In the use, after the valve plate 3 is opened and closed once, open the blowoff valve 9, the hydrops in valve body 1 inside and the main drainage pipeline alright with along outlet 8 and blowoff valve 9 flow to the external world to a series of problems such as hydrops freeze, valve failure, pipeline frost crack have been avoided producing.
