Abstract
The utility model relates to a gate valve shield for preservation and insulation, which comprises a T-shaped casing. The casing is provided with two portions which are connected by connectors. The utility model has the advantages of convenient utilization, labor and time saving, water-resistant and preservation, nice insulation effect, and is suitable to all kinds of gate valves.
Description
The utility model relates to the corrosion-resistant thermal insulation shell of gate valve.
Expose gate valve,, often be damaged by frost and damaged by physics mode because of its outer no corresponding protection measure at outdoor various pipelines.For addressing the above problem, people use materials such as asbestos, felt, sepiolite always by wrapping up and smearing gate valve and carry out heat insulation protecting.Because of above-mentioned material water proof not, easily seep water and freeze, so its heat insulation protecting weak effect causes gate valve by bursting by freezing and damage; Secondly, this method implements time-consuming; The 3rd, adopt the parcel heat preserving method to influence the gate valve operation.
The purpose of this utility model is to provide that a kind of easy to use, saving of work and time, water proof are anticorrosion, the gate valve corrosion-resistant thermal insulation shell of high insulating effect.
A kind of gate valve corrosion-resistant thermal insulation shell is made up of a housing that is " protruding " font, and above-mentioned housing is made up of two-part, and two-part of housing connect by link.
Above-mentioned corrosion-resistant thermal insulation shell, the inside of housing are spheroid or oval ball shape, with economical with materials and reducing cost.
Above-mentioned corrosion-resistant thermal insulation shell, housing by up and down or the front and back two halves form, be convenient to connect.
Above-mentioned corrosion-resistant thermal insulation shell, the edge of each half housing forms chimb, and above-mentioned link is located on the chimb.
Above-mentioned corrosion-resistant thermal insulation shell, two-part of housing are connected by screw rod.
Above-mentioned corrosion-resistant thermal insulation shell, two-part of housing are connected by rivet.
Above-mentioned corrosion-resistant thermal insulation shell, upper shed place of every partial shell are provided with semicircle cover plate with holes.
Be made up of a housing that is " protruding " font because of the utility model, above-mentioned housing is made up of two-part, and two-part of housing connect by link.During use, the lock that housing two-part is wrapped in gate valve is external, and inserts thermal insulating material between them, two housing sections is fixed by link again.Use the utility model protection gate valve, easy to operate, saving of work and time, water proof is anticorrosion, heat insulation effect is good, can avoid physical damage, moreover dismounting and parcel are very convenient, also reusable, and does not influence the operation of gate valve.The utility model is applicable to various gate valves.
Below in conjunction with embodiment the utility model is described in detail.
Fig. 1 is the plan view of half housing of the utility model embodiment.
With reference to Fig. 1, embodiment is made up of a housing 1 that is " protruding " font, the inside of housing is sphere-like, above-mentioned housing is made up of the front and back two halves, upper shed place of each half housing is provided with holes 3 semicircle cover plate 2, the edge of each half housing forms chimb 4, and chimb is provided with screw 5, and the two halves of housing connect by screw rod.
In the above-described embodiments, can be provided with sealing gasket between the chimb; Housing can be made up of two-part up and down; The inside of housing can be the oval ball shape; The two halves of housing can connect by rivet.
