Abstract

The invention relates to an asphalt circulating control valve body which comprises an asphalt control valve body. The asphalt circulating control valve body is technically characterized in that a first discharging hole, a second discharging hole, a third discharging hole and a feeding hole which are mutually communicated are formed in different walls of the asphalt control valve body; a heat flow inlet and a heat flow outlet are formed in the side wall of the asphalt control valve body; and a heat flow channel which is communicated with the heat flow inlet and the heat flow outlet and arranged along the edges of the asphalt control valve body is formed in the asphalt control valve body. According to the asphalt circulating control valve body, after heat flow is introduced into the heat flow channel, asphalt flowing through the asphalt control valve body can be heated to prevent the asphalt from cooling; and meanwhile, as the heat flow channel is arranged along the edges, the uniformity of the temperature of the asphalt control valve body can be ensured.

Description

A kind of pitch loop control valve body

[technical field]

The present invention relates to a kind of pitch loop control valve body.

[background technology]

Pitch spills cloth by pitch sprinkling car when being used for road pavement, pitch is encased in the asphalt tank spills cloth by distributing device, because pitch is solid-state or semisolid when the normal temperature state, caking property is strong, and is mobile poor, so pitch need could spray after heating.Existing pitch sprinkling car is that pitch heating back is directly sprayed mostly, because distributing device all is the normal temperature state before pitch pitch, when pitch when for the first time spray flow is through distributing device temperature will reduce, do not reach spray temperature, if so directly from nozzle, spray, might become semisolid, thus plug nozzle.Therefore need control valve to come pitch to reflux, and the pitch valve body need guarantee that certain temperature prevents bitumen solidification.

[summary of the invention]

The objective of the invention is to overcome the deficiencies in the prior art, a kind of hot flow path that has is provided, can guarantee that the valve body temperature prevents the pitch loop control valve body of bitumen solidification.

In order to address the above problem, the present invention by the following technical solutions:

A kind of pitch loop control valve body, comprise pitch control valve body, it is characterized in that: described pitch control valve body is provided with first discharging opening, second discharging opening, the 3rd discharging opening, the charging aperture that is interconnected at different walls, described pitch control valve body is provided with hot-fluid entrance and hot-fluid outlet at sidewall, and described pitch control valve body is provided with the heat passage of arranging the outlet of the described hot-fluid entrance of connection and hot-fluid along its sideline.

Aforesaid a kind of pitch loop control valve body, it is characterized in that: described first discharging opening, second discharging opening, the 3rd discharging opening are located at the first side wall respectively, second sidewall, on the 3rd sidewall, described charging aperture is located on the roof.

Aforesaid a kind of pitch loop control valve body, it is characterized in that: the outlet of described hot-fluid entrance and hot-fluid all is located on the described the first side wall, described heat passage successively along first limit, the layout on second limit, the 3rd limit, the 4th limit, the 5th limit, hexagon, the 7th limit.

Beneficial effect of the present invention has: pitch control valve body is provided with hot flow path, can in hot flow path, feed hot-fluid, guarantee that pitch control valve body temperature prevents bitumen solidification, heat passage successively along first limit, the layout on second limit, the 3rd limit, the 4th limit, the 5th limit, hexagon, the 7th limit, can guarantee that like this pitch control valve body temperature is even.

[specific embodiment]

Below in conjunction with accompanying drawing and the specific embodiment the present invention is described in further detail:

Extremely shown in Figure 8 as Fig. 1, a kind of pitch loop control valve body, comprise pitch control valve body 4, pitch control valve body 4 is provided with first discharging opening 41, second discharging opening 42, the 3rd discharging opening 43, the charging aperture 45 that is interconnected at different walls, first discharging opening 41, second discharging opening 42, the 3rd discharging opening 43 are located at the first side wall 48 respectively, on second sidewall, 49, the three sidewalls 50, charging aperture 45 is located on the roof 51.Pitch control valve body 4 is provided with hot-fluid entrance 2 and hot-fluid outlet 3 at sidewall, and pitch control valve body 4 is provided with the heat passage 1 of arranging the described hot-fluid entrance 2 of connection and hot-fluid outlet 3 along its sideline.Hot-fluid entrance 2 and hot-fluid outlet 3 all is located on the first side wall 48, heat passage 1 successively along first limit 11, the layout on second limit 12, the 3rd limit 13, the 4th limit 14, the 5th limit 15, hexagon 16, the 7th limit 17.When hot-fluid flow in the heat passage 1, can heat pitch control valve body 4, can heat the pitch in the pitch control valve body 4 of flowing through like this, prevent the pitch cooling, hot flow path is arranged along the sideline simultaneously, can guarantee that like this pitch control valve body temperature is even.
