Description

Filter for gas pressure regulating box

Technical Field

The utility model belongs to the technical field of town gas distribution equipment, the gas filter of town gas pressure regulating box specifically says so.

Background

With the popularization and application of gas energy, in order to meet the gas pressure requirements required by different users, a gas pressure regulating box is an indispensable pressure regulating device in a town gas transmission and distribution system. The pressure regulator in the gas pressure regulating box is more easily influenced by impurities in the gas along with the increase of the service time, and the service life is shortened. The filter is arranged in the air inlet pipe assembly of the pressure regulating box, and impurities in the fuel gas are filtered through the filter screen, so that the function of cleaning energy is achieved. The filter both ends are intake pipe and outlet duct, and the inside key part of filter is the filter screen. The traditional filter adopts the principle that an air inlet is communicated with a filter screen, and an air outlet is contacted with the outer wall of the filter screen. The gas enters the gas inlet, is removed by the gas outlet pipe on the outer wall of the filter screen after impurities are removed by the filter screen. Although the gas is filtered, the filtered dirt falls into the pipeline or the ball valve, so that great trouble is brought to impurity cleaning, normal use of other parts is influenced, and the filtering efficiency of the filter is influenced after long-time use.

Disclosure of Invention

The utility model provides a solve above-mentioned technical problem and provide a filter for gas pressure regulating box that filters more fully, effective edulcoration to easy blowdown.

The utility model discloses a solve foretell problem through following scheme: a filter for a gas pressure regulating box comprises a filter valve body, a filter screen, a blind flange, an air inlet pipe, an L-shaped air outlet pipe, a support plate, a baffle, a single-head cock and the like, wherein a flange is welded on an inlet pipe orifice and an outlet pipe orifice and is connected with an external pipeline; the gas inlet pipe, the filter valve body and the gas outlet pipe are perpendicular to each other and are not in contact with the wall of the filter valve body, and fuel gas enters the inner cavity of the filter through the gas inlet pipe; the filter screen is fastened on a support plate of an L-shaped opening of the air outlet pipeline by a pull rod, a nut and a baffle, the front end of the filter screen is sealed by a blind flange, and the filter screen is not contacted with the valve body wall of the filter; meanwhile, the filter valve body is provided with a vertically downward sewage draining port, and a single cock is installed on the sewage draining port.

The filter for the gas pressure regulating box provided by the utility model increases the size of the valve body of the filter, the filter is horizontally arranged,

because the filter valve body is large and is not in contact with the filter screen, the contact area of the fuel gas and the filter screen is large, and the fuel gas can be more fully filtered. After full filtration, the gas enters the filter screen and is discharged from the gas outlet, and the filtered impurities fall down and are discharged through the sewage outlet. The sewage draining port is arranged downwards and is vertical to the valve body, so that impurities can be effectively prevented from flowing into the next pipeline element; and can filter the impurity in the gas is effectual, still can handle alone to the impurity that filters out, avoided the secondary pollution to the gas.

Detailed Description

The structure and the working principle of the filter for the gas pressure regulating tank are explained in detail in the following with reference to three drawings, namely fig. 1, fig. 2 and fig. 3.

A filter for a gas pressure regulating box comprises a filter valve body (5), a filter screen (11), a blind flange (4), an air inlet pipe (2), an L-shaped air outlet pipe (3), a supporting plate (9), a baffle (13), a single-head cock (7) and the like. As shown in the figures 1 and 2, an air inlet pipe (2) is mutually vertical to an L-shaped air outlet pipe (3) and a filter valve body (5), a sewage discharge outlet (6) is parallel to the air inlet pipe (2) and is vertically downward, and fuel gas enters the filter valve body (5) from the air inlet pipe, is filtered by an internal filter screen (11) and is discharged from the air outlet pipe (3). The filtered impurities are discharged through a sewage discharge outlet (6), a single-head cock (7) is installed on the sewage discharge outlet (6), only when sewage is discharged, the single-head cock (7) can be opened, and the remaining time is in a closed state.

As shown in figure 3, in the filter, a support plate (9) is welded at the short end of an L-shaped air outlet pipe (3), one end of a pull rod (10) penetrates through the support plate (9) and is screwed on a threaded hole of the L-shaped air outlet pipe (3), a filter screen (a nut (12) penetrates through a baffle plate (13) and is screwed on the other end of the pull rod (10) to be 11) and sleeved on the pull rod (10), one end of the filter screen abuts against the support plate (9), and the other end of the filter screen is covered by the baffle plate (13) to fix the filter screen (11).

Furthermore, a blind flange (4) is arranged at the tail end of the filter valve body (5) to seal the whole valve body. The blind flange (4) is used as a port for replacing internal parts, and parts in the filter can be replaced after being detached.

The novel filter for the gas pressure regulating box is not limited to the structure, and any modification is performed on the basis of the structure, namely, replacement improvement is performed, and the novel filter is included in the novel protection range.
