Abstract
The invention relates to a wall-penetrating device matched with a stainless steel corrugated hose for gas delivery. In the conventional wall-penetrating box, the threaded joint of a gas angle valve and a base elbow is easy to loosen, so that gas leaks and a leakage test is difficult to perform. The wall-penetrating device for the stainless steel corrugated hose for gas delivery comprises a cassette seat, and is characterized in that: the lateral surface of the cassette seat is provided with a gap, a 90-degree base elbow is fixed on the bottom surface of the cassette seat, the side end of the base elbow is provided with a thread interface, and a gas angle valve matched with the thread interface is arranged at the outer end of the base elbow. Through the wall-penetrating device, great convenience is brought to installation construction, torsion generated when the gas angle valve is installed on the base elbow is greatly reduced, and the strength requirement and the installation requirement on the cassette seat can be reduced; meanwhile, the potential safety hazard of gas leakage because the joint of the gas angle valve and the base elbow loosens is eliminated, and the leakage test is convenient to perform.
Description
Technical field
The wall fixing device when the present invention relates to flexible pipe and secretly burying, specifically a kind of and combustion gas carried with stainless steel ripple flexible pipe is matching used and gone out wall device.
Background technique
In recent years, China has begun to apply combustion gas and has carried with stainless steel ripple flexible pipe, and the cities such as Beijing, Shanghai, Shenyang, Shenzhen have obtained larger area and applied.Generally adopt the surface mode at present in engineering design and on-the-spot installation, directly burying wall uses few, on the one hand dark buriing work difficulty is large, go out on the other hand the auxiliary products imperfection of wall, carry with affecting combustion gas the popularization of using stainless steel ripple flexible pipe, because secretly bury and can not affect indoor finishing effect, along with whole society's growth in the living standard, people will be more and more higher to the requirement of the each side in room, so all there is higher requirement the aspects such as property easy for installation, functional reliability and aesthetics of functional product.According to the research of combustion gas being carried with stainless steel ripple hose wall box, it need possess following functions: 1) easy for installation, by the simple construction and installation in scene, and can reach linking intensity and seal request; 2) must possess very high safety and reliability; 3) outward appearance is beautiful, can be complementary with the fashion finishing.
For solving the problem of above-mentioned existence, Chinese utility model patent 200820165925.1 discloses a kind of combustion gas with non-scale corrugated stainless steel tubing out-of-wall box, but still there are in actual use some problems: 1, in order to ensure bearing the larger torsion that produces when the combustion gas angle valve tightens to the base elbow by pipe thread, adopted the cassette seat side to be provided with pillar, but due to the existence of pillar, operation easier is very large when mounted; 2, when the combustion gas angle valve tightens to the base elbow by pipe thread, angle owing to tightening may require with the angle of reality not to be inconsistent, be wound around raw meal belt or return stubborn angle valve and realize that the position of angle valve fixes by increase, therefore stay potential safety hazard, when twisting combustion gas angle valve handle in the counterclockwise direction, valve body does not rotate, and the threaded connection place of combustion gas angle valve and base elbow but produces unclamps, and causes gas leakage; 3, after installation, leakage test need to be done in the threaded connection place of combustion gas angle valve and base elbow, is in the inside of cassette seat owing to being threaded, and is difficult to do leakage test; 4, erecting of panel owes desirable, and because panel directly is fixed on cassette seat, the position of cassette seat has directly determined the position of panel, there is no the leeway of adjusting, is not easily just producing, and is not concordant with metope, gives prominence to or sink to metope.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, provide a kind of and combustion gas to carry with stainless steel ripple flexible pipe is matching used and go out wall device, it makes the multiple linkage structure that adopts the cylinder type sealing between combustion gas angle valve and base elbow, carves formula location and screw-threaded coupling, to avoid gas leakage, conveniently carry out leakage test.
For this reason, the present invention adopts following technological scheme: combustion gas is carried with stainless steel ripple hose wall device, comprise cassette seat, the side opening that it is characterized in that described cassette seat is jagged, fix one 90 degree base elbows on the bottom surface of cassette seat, the side of base elbow is a threaded coupling, the outer end installation one of base elbow and the combustion gas angle valve of its coupling;
The outer end of base elbow is provided with outside thread, port is provided with two symmetrical boss, described combustion gas angle valve comprises the piston rod of deploying in the base elbow, piston rod is provided with four opening slots of circumference uniform distribution, according to different directions, select two opening slots wherein to embed in described two boss, convenient location; The bottom of piston rod is provided with at least one circle groove, and groove is built-in with O-ring seals; Piston rod is provided with a circle locating slot, its embedded slotted collar, upper cover of piston rod has set screw nut, described slotted collar is placed in set screw nut, the outside thread of the internal thread of set screw nut and base elbow is complementary, and the connection by internal and external screw thread is fixed on the bottom of piston rod on the outer end of base elbow.
As preferably, the outer end of described base elbow cover has a stainless steel faceplate that is positioned at the set screw nut inboard, and stainless steel faceplate is used for hiding base elbow and cassette seat.
As preferably, the outside of described set screw nut is threaded, and being enclosed within has the internal thread that is complementary with screw thread in the sheathing on piston rod, by tightening sheathing, stainless steel faceplate is pressed abd fixed on metope.
As preferably, the external diameter after described slotted collar is shunk is less than the screw thread path of set screw nut, greater than the bottom outlet of nut, reaches by set screw nut the combustion gas angle valve is fastened on purpose on the base elbow.
The beneficial effect that the present invention has: the gap structure of cassette seat side greatly facilitates installation; Adopt the cylinder type sealing between combustion gas angle valve and base elbow, carve the formula location, the multiple linkage structure of screw-threaded coupling, the torsion that produces when greatly reducing the combustion gas angle valve and being installed on the base elbow, can reduce requirement of strength and installation requirement to cassette seat, eliminate simultaneously because the joint of combustion gas angle valve and base elbow produces and unclamped the potential safety hazard that causes gas leakage; The joint of combustion gas angle valve and base elbow is arranged on the outside of panel, conveniently carries out leakage test; Adopt panel to be sleeved on the base elbow, by tightening sheathing, panel is pressed abd fixed on metope, both random adjusting angle, can realize conveniently again that panel coordinated with the ideal of metope, panel and base elbow have certain adjustable range, have reduced the difficulty of construction of installing.
The present invention is further illustrated below in conjunction with specification drawings and specific embodiments.
