Abstract
The utility model discloses a vehicle-used asphalt valve, which comprises a valve body, wherein a discharge pipe orifice is formed on the side wall of the valve body, a sealing cover is arranged at one end of the valve body, a flange is arranged at the other end of the valve body, a shaft sleeve is arranged in the sealing cover, a screw rod is installed in the shaft sleeve and extends into the valve body, a rotating handle is arranged at one end of the screw rod, and a retaining ring is arranged at the other end of the screw rod. The vehicle-used asphalt valve can achieve the purposes of rapid asphalt discharge, good sealing performance and high security, can normally work under the conditions that the temperature is no higher than 300 DEG C and the pressure is no higher than 1 MPa, costs lower and is suitable for mass production.
Description
Technical field
The utility model relates to tank car and uses the device field, is specially a kind of automobile-used asphalt valve.
Background technique
Pitch is one of structural material commonly used in the building field, because asphalt viscosity is bigger, need transport with the tank car of special use.For the special-purpose tank car that loads pitch, because asphalt viscosity is big, behind loading, need heating, require the asphalt valve can be high temperature resistant, and bear certain jar internal pressure, also require asphalt valve easily to open and close simultaneously, sealing is reliably.The asphalt valve complex structure of conventional art, sealing and poor stability, cost is higher.
The model utility content
The purpose of this utility model provides a kind of automobile-used asphalt valve, to solve asphalt valve sealing, the poor stability of prior art, cost problem of higher.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of automobile-used asphalt valve, include the valve body of tubulose, described body wall be equipped with valve body in the discharging mouth of pipe that is communicated with, it is characterized in that: described valve body one end valve mouth is covered with sealing cover, the other end valve port is equipped with flange, tapped axle sleeve is installed in the described sealing cover, there is screw mandrel to be installed in the axle sleeve and stretches in the valve body, described screw mandrel is positioned at the outer termination of valve body handle with sleeve is installed, the back-up ring that the end that screw mandrel is positioned at valve body is vertically installed with shape and valve body cross-sections match and fits with valve interior wall with respect to screw mandrel, described back-up ring can be pressed on and constitute sealing on the flanged surface.
Described a kind of automobile-used asphalt valve is characterized in that: the end that described screw mandrel is positioned at valve body is vertically installed with two sealing baffles that are parallel to each other with respect to screw mandrel, and described back-up ring is clipped between two sealing baffles.
Described a kind of automobile-used asphalt valve is characterized in that: described flange center also be equipped with valve body in be communicated with block up, the described front end of blocking up is covered with the blanking cover plate.
In the utility model, valve body is installed to by flange on the tank body of tank car, and screw mandrel rotates around the valve body center under the effect of handle with sleeve and moves in valve body; Usually back-up ring supported flange face forms sealing under the state; Being movable to discharging mouth of pipe back when discharging allows liquid flow out fast.The utility model can be realized quick pitch discharging, and good airproof performance is safe, can be not more than 300 ℃ in temperature, and pressure is not more than proper functioning under the 1MPa, and cost is lower, can mass production.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of automobile-used asphalt valve, include the valve body 6 of tubulose, valve body 6 sidewalls are equipped with and the valve body 6 interior discharging mouths of pipe 7 that are communicated with, valve body 6 one end valve mouths are covered with sealing cover 8, the other end valve port is equipped with flange 1, flange 1 center also is equipped with and valve body 6 interior blocking up of being communicated with, and the front end of blocking up is covered with blanking cover plate 2.Tapped axle sleeve 10 is installed in the sealing cover 8, there is screw mandrel 5 to be installed in the axle sleeve 10 and stretches in the valve body 6, screw mandrel 5 is positioned at valve body 6 outer terminations handle with sleeve 9 is installed, the back-up ring 3 that the end that screw mandrel 5 is positioned at valve body 6 is vertically installed with shape and valve body 6 cross-sections match and fits with valve body 6 inwalls with respect to screw mandrel 5, back-up ring 3 can be pressed on 1 of flange and go up and constitute sealing.The end that screw mandrel 5 is positioned at valve body 6 is vertically installed with two sealing baffles that are parallel to each other 4 with respect to screw mandrel 5, and back-up ring 3 is clipped between two sealing baffles 4.
