Description
Technical Field
The invention relates to a valve, in particular to a fitting type quick breather valve.
Background
At present, the existing tank top breather valve consists of accessories such as a valve seat, a valve cover, a valve disc, a guide pillar, a pressing plate, a spring and the like. When the breather valve needs to exhale the gas in the tank, the exhale port valve disc moves upwards along the valve cover through the guide pillar. When inhaling, the suction inlet valve disc moves upwards along another valve gap through the guide post. The top end of the guide post and the guide hole of the valve cover form an operation space, namely a small top end air-tight chamber. If the gas in the tank entrains fine powder or has adhesive medium, a closed space is formed in the operation space, and when the breathing valve disc is rapidly opened upwards in the exhalation inhalation movement, a small airtight chamber is formed in the closed space, so that the valve disc cannot be opened or the opening height is insufficient, or the breathing valve disc slowly operates, and the breathing function fails.
Moreover, the connecting space between the exhale outlet and the suction inlet is too large, a concave groove is formed at the suction inlet, condensed water liquid or falling objects are easy to accumulate, and when the temperature is low, the valve disc is easy to freeze, foreign matters are easy to be mixed at the sealing port of the valve disc, so that the respiratory function is invalid.
The valve disc of the breather valve is guided by four guide posts or three guide posts, and the valve disc is easy to clamp and fail.
When the respiratory function fails, the liquid in the tank is evaporated or leaked, the environment is damaged, and the tank is exploded and imbibition is unstable due to serious conditions.
Disclosure of Invention
The invention aims to provide a fitting type quick breather valve, which solves the problems that the valve cover of the existing fitting type quick breather valve is inflexible and has a clamping effect when being opened; the breather valve is flexible to open, free of blocking, even in stress, good in sealing effect, capable of guaranteeing effective balance of pressure in the tank and relieving safety accidents caused by failure of the breather valve.
In order to achieve the above purpose, the technical scheme of the invention is as follows:
the fitting type quick breather valve comprises a valve seat, a valve seat and a valve seat, wherein the valve seat is a flange type ring body, two sides of the upper end surface of the valve seat are symmetrically and vertically provided with supporting columns respectively, and a position through hole is formed in the upper part of each supporting column; the outer side surfaces of the valve seat, which are opposite to the support columns in the circumferential direction of the valve seat and form a 90-degree direction, are respectively provided with a fixing column in a protruding mode, and the two fixing columns are symmetrically arranged; the bridge is a rod body, two ends of the bridge are bent downwards to form positioning parts, and the positioning parts are provided with connecting holes corresponding to the positioning through holes at the upper parts of the support columns and are positioned through bolts; the center of the bridge is provided with a center guide sleeve seat, and the center of the center guide sleeve seat is provided with a through hole; the guide sleeve is arranged in the through hole in the center of the center guide sleeve seat; the sliding sleeve is arranged in the guide sleeve, and the lower end of the sliding sleeve extends out of the bottom surface of the bridge; the spring fixing seat is arranged in the center of the bottom surface of the bridge, a central through hole is arranged in the center of the spring fixing seat and corresponds to the through hole in the center of the central guide sleeve seat, and a groove for inserting the lower end of the sliding sleeve is formed in the upper part in the central through hole in a surrounding manner; the center support is inserted into the sliding sleeve and connected with the sliding sleeve through a screw; the lower part of the central support column passes through the central through hole of the spring fixing seat; the upper valve cover is a ring body, a cross-shaped supporting rod is arranged at the center of the upper valve cover, a boss is arranged at the center of the cross-shaped supporting rod in a protruding mode, and a first center hole is formed in the center of the boss; the diameter of the upper valve cover is larger than the inner diameter of the valve seat ring body; the valve cover positioning sleeve is arranged in the first central hole of the upper valve cover boss; the spring is sleeved on the central support column between the bridge frame and the upper valve cover, the upper end of the spring is fixed on the spring fixing seat, and the lower end of the spring is fixed on the boss of the upper valve cover; the lower valve cover is a circular plate body, a second central hole for the central pillar to pass through is formed in the center of the lower valve cover, the second central hole is a screw hole and is fixed on the central pillar through a bolt lock, and the lower valve cover is positioned in the valve seat ring body; the diameter of the lower valve cover is larger than the inner diameter of the upper valve cover ring body and smaller than the inner diameter of the valve seat ring body; the protection cover is covered on the valve seat, and the lower end of the protection cover is connected with the upper support column and the fixed column of the valve seat through bolts.
Preferably, the upper end face of the valve seat is vertically provided with a supporting column along the two sides of the central direction of any flange two holes of the circumference of the valve seat, the outer side face of the valve seat, which forms a 90-degree direction relative to the central connecting line of the supporting column, is respectively provided with a fixing column in a protruding mode, and the two fixing columns are symmetrically arranged.
Preferably, four positioning holes are uniformly formed in the lower portion of the side wall of the protective cover along the circumferential direction, and the four positioning holes are connected to a support column and a fixing column of the valve seat through a spacer and locked by screws.
The bridge is fixed on two supports of the valve seat through four bolts to form a stable and rigid guide frame. The center pillar sliding sleeve slides freely up and down along the guide sleeve along with positive pressure and negative pressure of gas in the tank so as to drive the upper valve cover and the lower valve cover to flexibly and stably and freely open and close, and the effective sealing area of the sealing part of the valve cover is also ensured. When the pressure of the gas in the tank exceeds the pressure of the valve cover and the spring, the valve cover is ejected out, and when the pressure of the gas in the tank is smaller than or equal to the pressure of the valve cover and the spring, the valve cover is closed; and the valve cover is pressed under the action of spring pressure to keep sealing.
In particular, compared with the existing split breather valve, the sliding sleeve structure of the invention has the advantages that the central support column and the valve cover do not form a sealing structure. So-called hermetic seals. Thus, the valve disc can be flexibly moved up and down.
In addition, compared with the four guide posts or three guide post valve disc guiding structures adopted by the existing breather valve, namely the pillar structure of the upper valve disc, the valve disc has good center contact ratio, and the valve disc cannot be clamped because the moving centers of the four guide posts or the three guide posts are not overlapped.
The invention has the beneficial effects that:
the upper valve cover and the lower valve cover can freely and flexibly operate up and down without blocking; and is sealed and effective in time. When the excessive pressure in the tank needs to be released, the upper valve cover and the lower valve cover are opened, and part of gas is discharged to reach an equilibrium state. When the partial gas pressure needs to be supplemented in the tank, the lower valve cover is opened, and the sucked partial gas reaches the balance of the gas in the tank.
