Description
Technical field
The utility model relates to gate valve field, is specifically related to a kind of petroleum pipeline and asphalt delivery Wear-resistant, high-temperature resistant gate valve.
Background technique
Gate valve is an open-shut device flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, uncomfortable door parameter and different.Can improve its manufacturability, make up the deviation that sealing surface angle produces in course of working, this flashboard is called Flexible disc.Gate valve is a conventional valve body, but existing valve body intelligence is used for the transmission of usual liquid, requires higher situation then and inapplicable for special or precision etc., and especially the stickiness such as oil or pitch is higher, and needs the liquid of high temperature to be then not suitable for.This gate valve adopts the mode of enlarged contact areas to reduce pressure, has reached the effect of Wear-resistant, high-temperature resistant.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of petroleum pipeline and asphalt delivery Wear-resistant, high-temperature resistant gate valve.
The technical problem that the utility model solves can realize by the following technical solutions: a kind of petroleum pipeline and asphalt delivery Wear-resistant, high-temperature resistant gate valve, comprise gate valve body, wherein said gate valve body comprises valve body, the center of valve body is provided with valve rod, valve rod is provided with sealed pipe, the inwall of sealed pipe is provided with anti-slip veins, the two ends up and down of sealed pipe are equipped with bezel ring, bezel ring, is provided with buckle, the top of valve rod is provided with handwheel, the below of handwheel is provided with Stuffing box, Stuffing box is provided with material feeding mouth, valve gap is provided with below Stuffing box, the side of valve gap is provided with shrouding, the surface of shrouding is provided with inorganic coating, valve gap is positioned at directly over valve body, the below of valve rod is provided with flashboard, flashboard is positioned at the centre of valve body, the surrounding of flashboard is provided with some grooves be evenly distributed, the below of flashboard is provided with adjustment hole, adjustment hole is oval.
Preferably, described bezel ring, with between sealed pipe for being threaded.
Preferably, pad is provided with between described valve gap and valve body.
Preferably, the both sides of described handwheel are provided with Anti-slip cover.
Preferably, locating column is provided with in the middle of described adjustment hole.
Beneficial effect is: this gate valve is for petroleum pipeline and asphalt delivery, this gate valve adopts the mode of many places sealing can improve the sealing of gate valve, and the many places of gate valve increase area with reduces gate valve in use oil or pitch to the pressure of gate valve, thus raising gate valve wear resistance and can make increase the working life of gate valve.The valve rod of the centre of this gate valve adds sealed pipe, effectively can prevent the contact between oil and valve rod, thus reduce the corrosion to valve rod, and the working life of valve rod is increased.Inorganic coating on shrouding on valve gap, makes this gate valve can be effectively high temperature resistant.Gate valve simultaneously under valve rod is provided with groove, can cushion the flow velocity passing lyophobe, and adjustment hole can limited flow, and the locating column in adjustment hole can locating rams, also can not limit the motion of flashboard.
