Description

Valve body

Technical Field

The utility model relates to a valve body.

Background

The existing valve body comprises a decoration panel and an annular sleeve, wherein the annular sleeve is provided with an air inlet and an air outlet, and the decoration panel is connected with the annular sleeve into a whole in a welding mode after being sleeved at the middle position of the annular sleeve. However, existing trim panels have difficulty in accurately controlling their welding location on the annulus.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that a valve body is provided, the problem that the welding position of decoration panel on the ring sleeve is difficult to accurate control has been solved.

In order to solve the above problem, the utility model provides a following technical scheme:

the valve body includes the ring conduit, the ring conduit sets gradually along the exhaust direction peg graft pipe, decoration panel and blast pipe, peg graft and be equipped with the air inlet on the pipe, be equipped with the gas vent on the blast pipe, the blast pipe includes the slope section, the slope section upwards extends, and, the gas vent is located slope section top, its characterized in that, peg graft the pipe in order to be distinguished from the mode setting of blast pipe is in on the decoration panel.

According to the invention, the insertion pipe, the decoration panel and the exhaust pipe are divided into three parts, wherein the insertion pipe and the exhaust pipe are respectively arranged on the decoration panel. So design, the valve body can be according to the demand, with the blast pipe setting of the grafting pipe of different specifications and different specifications on the decoration panel to the length dimension of accurate control valve body at the decoration panel is positive, the length dimension of accurate control valve body at the decoration panel reverse side. Because the sealing performance (need the leak protection cigarette) between grafting pipe and the decoration panel requires to be different from the sealing performance (firm in connection, preferred scheme, leak protection cigarette) between blast pipe and the decoration panel and requires, consequently, the grafting pipe sets up on the decoration panel with the mode that is different from the blast pipe, and this structure can effectively shorten the manufacturing cycle of valve body, reduces the manufacturing cost of valve body.

Furthermore, the inserting pipe and the decorative panel are integrally formed, and the exhaust pipe is welded on the decorative panel. The phenomenon of smoke leakage at the joint of the splicing pipe and the decoration panel can be effectively avoided by integrally forming the splicing pipe and the decoration panel, namely, when the splicing pipe and the decoration panel are integrally formed, the step of detecting the sealing performance between the splicing pipe and the decoration panel can be usually omitted. In addition, the blast pipe welding can improve the production efficiency of valve body on the decoration panel.

Furthermore, the splicing pipe and the decorative panel are formed by stretching a metal plate. The structure further reduces the manufacturing cost of the valve body and further improves the production efficiency of the valve body.

Further, the exhaust port is arranged on the inclined section and is arranged obliquely; the inclined section is an arc-shaped section, and the arc center angle corresponding to the arc-shaped section is less than or equal to 90 degrees. By the design, gas backflow can be prevented, and flue gas in a flue (the flue is arranged in a residential building, and residents on different floors are communicated with the flue through the fireproof check valve) can be prevented from moving upwards from bottom to top and directly flows into the exhaust passage through the exhaust port.

Furthermore, the exhaust pipe also comprises a vertical section arranged above the inclined section, and the exhaust port is arranged on the vertical section; the exhaust pipe further comprises a horizontal section arranged on one side of the inclined section, and a locking structure used for fixing the smoke isolating valve plate is arranged on the horizontal section and/or the inclined section. The vertical section reduces the difficulty of opening the exhaust port, and the horizontal section reduces the difficulty of opening the air inlet.

Furthermore, the area of the air inlet is smaller than that of the air outlet. This construction provides the valve body with a "suction" effect.

Further, the exhaust duct is welded to the rear surface of the decorative panel. This structure avoids the front phenomenon of leaking the cigarette of taking place of decoration panel.

Furthermore, one end of the insertion pipe, which is far away from the decoration panel, is provided with a first flanging which is bent inwards. This structure avoids the air inlet on the grafting pipe with user's hand fish tail.

Furthermore, a second flanging bent along the exhaust direction is arranged on the periphery of the decorative panel, a sealing ring is arranged on the decorative panel and is arranged on the back of the decorative panel, and the thickness of the sealing ring is larger than the length of the second flanging. The second flanging is used for accommodating and protecting the sealing ring.

Furthermore, one end of the exhaust pipe close to the decoration panel is provided with a third flanging which is bent outwards. The third flanging reserves a welding position for the exhaust pipe.
