Valve is high-temperature, high-accuracy, and high-frequency glue spraying equipment, its heat-proof quality and sealing property are particularly important, in particular for
Glue inlet tube road plays the important function of key with the thermal insulation board of the spaced heat of valve body and the dynamic seal of sealing striker.Piezoelectricity drives
Dynamic PUR injection valve, which needs to carry out the PUR in glue inlet tube road up to 120 ° -180 ° of heating, could change PUR
Mobility realizes injection, and the high heat in glue inlet tube road can be transmitted to piezoelectric stack by valve body, and this part high heat can increase
Add the temperature of the piezoelectric stack under normal temperature work, the service life of the piezoelectric stack to work at high temperature for a long time can greatly contract
It is short, and driving part of the piezoelectric stack as core, either its production cost or installation cost are all very high, so entering glue
It is heat-insulated most important between pipeline and valve body.Other dynamic seal is different from conventional seals circle, and shape is tapered, directly pacifies
It is very difficult on glue inlet tube road, and its material is softer, is easily deformed by external force effect, the dynamic sealing of deformation encloses
Less than the sealing function to striker, and striker can be caused to drive glue spill valve when moving and can not work, so installation is dynamic
The device of state sealing ring is also most important.The utility model designs a kind of new type hot-melt adhesive injection valve thermal insulation board and subtracted by heat-insulated
The contact area in few glue inlet tube road and thermal insulation board, increases the distance between glue inlet tube road and valve body, can effectively play into glue
Heat-blocking action between pipeline and valve body and there is dynamic seal mounting groove, pass through the side directly assembled with dynamic seal
Method to dynamic seal fixation plays a part of protection, it is not easily susceptible to external force directly effect and is deformed.
Utility model content
In order to solve, the glue inlet tube road heat present in prior art is transmitted to the valve body shortening piezoelectric stack life-span and dynamic is close
The defects of seal is easily deformed, the utility model provide heat transfer between a kind of barrier glue inlet tube road and valve body and mitigated dynamically close
The new type hot-melt adhesive injection valve thermal insulation board of seal abrasion deformation.
Technical scheme is used by the utility model solves its technical problem：
A kind of new type hot-melt adhesive injection valve thermal insulation board, described thermal insulation board are fixedly mounted between glue inlet tube road and valve body,
Described thermal insulation board includes the first mounting surface towards valve body and the second mounting surface towards glue inlet tube road, on described thermal insulation board
Provided with the striker access hole for installing striker, described striker access hole is provided with close to one end of the second mounting surface to be used to install
The mounting groove of dynamic seal, described dynamic seal and mounting groove interference fit, described dynamic seal are closely surrounded
Around striker.
Further, described thermal insulation board is polyether-ether-ketone thermal insulation board.
Further, the installation that the second described mounting surface is provided with positioned at middle intermediate lands and positioned at both sides is convex
Platform, described striker access hole are located at the center of intermediate lands, and described installation base center is provided with mounting hole, described
The screw for being fixedly connected with glue inlet tube road, thermal insulation board and valve body is provided with mounting hole.
Further, described thermal insulation board is provided with positioning hole, and described valve body is determined provided with what is be engaged with positioning hole
Position pin.
Further, the second described mounting surface is provided with sealing ring mounting groove, is provided with described sealing ring mounting groove
The sealing ring that will be sealed between thermal insulation board and glue inlet tube road.
Further, described striker access hole is being provided with PUR discharge groove close to one end of the first mounting surface.
Beneficial effect：
(1) it is simple in construction, it is easy to process, it is cheap, it is easily installed and dismantles and maintenance.
(2) dynamic seal is fitted and fixed in PUR injection valve thermal insulation board, is not easily susceptible to dynamic seal
The effect of ambient pressure and deform, improve the service life of dynamic seal.
(3) intermediate lands and installation base are used, reduces the contact area of thermal insulation board and glue inlet tube road, increase glue inlet tube road
The distance between valve body effectively plays the heat-blocking action between glue inlet tube road and valve body.
(4) thermal insulation board use peek (polyether-ether-ketone) material, it is lower than the heat conductivility of metal material, preferably play every
Heat effect, protect piezoelectric stack not influenceed by high heat, extend the life-span.
(5) PUR tap is set, the PUR of spilling is discharged, prevents PUR from flowing into valve body to cores such as piezoelectric stacks
Center portion part causes to damage, and finds the abrasion of dynamic seal in time, is changed as early as possible, reduces loss.
