Abstract
The invention relates to a jacketed heat insulation gate valve. The jacketed heat insulation gate valve comprises a valve body and a valve seat which is arranged on the valve body, wherein an inlet and an outlet are formed at two ends of the valve body in pipeline direction respectively and connected with a pipeline. The jacketed heat insulation gate valve is characterized in that: a wedge-shaped elastic gate plate is arranged in the valve body; a sealing pair is arranged between the valve body and the wedge-shaped elastic gate plate; a valve body jacket is arranged on inner blocking parts at two ends of the valve body and on an outer wall of the valve body; and a sewage draining outlet and a drain outlet are formed at the bottom of the valve body jacket and in the front of the valve body jacket respectively. When the jacketed heat insulation gate valve operates in a normal system, the gate plate is opened, and a medium in the system flows from the inlet to the outlet; and when the jacketed heat insulation gate valve is restarted to operate after a longer time, a viscous medium may influence the on-off action of the valve, and the medium into which a heat source such as steam is fed passes through a cavity which is formed by the valve body and the valve body jacket so as to play a role in heating and heat insulation in a process system, so that blocking of a valve port by the cooled and crystallized medium is avoided, influence of the viscous medium on the on-off action of the valve is avoided, and the normal operation of the system is guaranteed.
Description
Technical field
The present invention relates to a kind of gate valve structure, especially relate to a kind of jacketed type insulation gate valve structure that is applied to.
Background technique
Gate valve is widely used in every field such as oil, chemical industry, power station and rock gas, and with respect to the valve of other controlling plumbing fixtures medium circulations, gate valve can provide the almost advantage of expedite MEDIA FLOW in the enable possition.The valve inner medium channel leads directly to, and medium is in line mobile, and flow resistance is little.
Compare with other class valves, more laborsaving during keying, because no matter be out or close, the ram movement direction is all perpendicular with the media flow direction, and water hammer is difficult for producing.Gate valve passage both sides are symmetrical, and medium can flow to the both sides any direction, are easy to install.But existing gate valve is when having medium to flow out, and often because the medium crystallisation by cooling stops up valve port, and the medium of viscosity can hinder the on-off action of valve, and the system that influences moves normally.
Summary of the invention
At the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of and can be incubated and prevent the medium crystallization, the jacketed type insulation gate valve of good seal performance and operation light and flexible, the system that guaranteed moves normally.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of jacketed type insulation gate valve, comprise valve body and the valve seat that is arranged on the valve body, the two ends of described valve body pipeline direction are respectively equipped with inlet/outlet, and be connected with pipeline, it is characterized in that the wedge shape Flexible disc is arranged in valve body, be provided with sealing pair between this valve body and the wedge shape Flexible disc, interior crotch part at the valve body two ends is provided with the valve body chuck with the valve outer wall place, is respectively equipped with sewage draining exit and floss hole in described valve body chuck bottom and front portion.
Above-mentioned jacketed type insulation gate valve, wherein, by being made of welded connection, the both sides of valve body chuck are welded together with the interior crotch bottom of the inlet/outlet at valve body two ends respectively described valve body chuck by the end socket of forward and backward two chucks and bottom.
Above-mentioned jacketed type insulation gate valve, wherein, above-mentioned valve body is the T-valve body.
Above-mentioned jacketed type insulation gate valve, wherein, above-mentioned valve seat and valve body are by firm the linking into an integrated entity of welding manner.
When normal system works, flashboard is opened, medium in the system flows to outlet from import, but when restarting work again after the long period, the medium of viscosity can hinder the on-off action of valve, in the time of will feeding the cavity of thermal source medium such as steam by valve body and chuck formation this moment, in process system, play the effect of heating and insulation, the system that guaranteed moves normally, add elasticity wedge shape flashboard and have little change elastic compensating ability, both guaranteed sealability, and made technology succinct again, the operation light and flexible.
The present invention is applicable on pipeline and does to open and close usefulness, and can be incubated and prevent the medium crystallization, selects different materials for use, can be applicable to multiple media such as heavy oil, glue class, nitric acid, acetic acid, strong oxidizing property medium and urea respectively.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the broken section signal of one embodiment of the invention.
Among the figure: 1, valve body, 2, valve seat, 3, elasticity wedge shape flashboard, 4, sewage draining exit, 5, floss hole.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, present embodiment provides a kind of jacketed type insulation gate valve, the valve body 1 that T shape is arranged, valve seat 2 and valve body 1 linking into an integrated entity by firm welding, wedge shape Flexible disc 3 is arranged in the valve body 1, between valve body 1 and the wedge shape Flexible disc 3 sealing pair is arranged, there is inlet/outlet at the two ends of valve body 1 pipeline direction, are connected with pipeline.
There is valve body chuck 6 at interior crotch part, valve outer wall place at valve body 1 two ends, this valve body chuck 6 by the end socket of forward and backward two chucks and bottom by being made of welded connection, the both sides of valve body chuck 6 are welded together with the interior crotch bottom of the inlet/outlet at valve body two ends respectively, have sewage draining exit 4 and front portion to be provided with floss hole 5 in the bottom of valve body chuck 6.
When normal system works, flashboard is opened, medium in the system flows to outlet from import, but when restarting work again after the long period, the medium of viscosity can hinder the on-off action of valve, in the time of will feeding the cavity that thermal source medium such as steam forms by valve body 1 and valve body chuck 6 this moment, and the effect of in process system, playing heating and being incubated, the medium of having avoided the medium crystallisation by cooling to stop up valve port and viscosity can hinder the on-off action of valve, has guaranteed the normal operation of system.
The present invention has little change elastic compensating ability by elasticity wedge shape flashboard 3 is set again, has both guaranteed sealability, makes technology succinct again, the operation light and flexible.It is applicable on pipeline does to open and close usefulness, and can be incubated and prevent the medium crystallization, selects different materials for use, can be applicable to multiple media such as heavy oil, glue class, nitric acid, acetic acid, strong oxidizing property medium and urea respectively.
