Abstract
The utility model discloses a sea valve installed at the bottom of a storage tank, comprising a valve body, a valve cap, a valve clack, a mandril, a piston, a piston rod, a piston cylinder and a pneumatic joint, wherein the piston cylinder is formed by fixedly connecting a gas cap with a bottom cylinder; the top of the valve body is provided with an oil hole which is covered by a filter screen; the valve clack is fixedly connected with the mandril which is sheathed with a return spring; one end of the return spring props against the valve cap, and the other end thereof props against the valve clack; the piston rod is fixedly connected with the piston in the piston cylinder; the front end of the piston rod pushes against the mandril; the pneumatic joint is communicated with the cavity of the piston cylinder; the valve body is provided with an emergency cutout groove which is positioned in the outer wall of the right side of the flange plate of the valve body; the rear end of the bottom cylinder of the piston cylinder is screwed with a bolt; and the front end of the bolt pushes against the rear end of the piston rod. The sea valve installed at the bottom of the storage tank can prevent the liquid in the storage tank from leaking and has good transportation safety.
Description
Technical field
The utility model relates to the tank truck field, specifically, relates to a kind of sea cock and valve that is installed in the tank bottom of tank truck.
Background technique
Sea cock and valve is installed in the bottom of the storage tank of tank truck, is used for from the tank bottom charge of oil, during oil-feed, drive piston by air inlet, piston rod withstands push rod, backs down the flap of fixedlying connected with push rod, make valve open, oil enters body cavity from oilhole, is entering storage tank from body cavity.But there is such shortcoming in traditional sea cock and valve, and when tank car bottom pipeline was subjected to powerful collision, storage tank can not separate with a car bottom jar pipeline, can cause leaked liquid in the tank body, the Security of influence transportation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can prevent leaked liquid in the storage tank, the sea cock and valve that is installed in tank bottom that Transport Safety is good.
The technological scheme that realizes above-mentioned purpose is: a kind of sea cock and valve that is installed in tank bottom, comprise valve body, valve gap, flap, push rod, piston, piston rod, piston cylinder and pneumatic joint, piston cylinder is formed by fixedly connecting by gas lid and bottom cylinder, the valve body top has oilhole, and on oilhole, be coated with filter screen, flap is fixedlyed connected with push rod, be set with Returnning spring on the push rod, one end of Returnning spring is against on the valve gap, the other end is against on the flap, piston rod is fixedlyed connected with the piston in the piston cylinder, the front end of piston rod props up push rod, pneumatic joint is communicated with the piston cylinder inner chamber, and valve body is provided with the emergency cut-off groove, and this emergency cut-off groove is positioned on the outer wall on flange plate right side of valve body.
Further, the rear end of the end cylinder of piston cylinder is connected with emergent bolt, and the front end of this emergent bolt props up the rear end of piston rod.
After adopting technique scheme, when the tank car bottom is subjected to powerful collision, the emergency cut-off groove of sea cock and valve will rupture automatically, make storage tank separate with car bottom pipeline, become the tank body of independent sealing, thereby prevent that pot liquid from leaking, improve the Security of transportation greatly.
Description of drawings
Fig. 1 looks cross-sectional view for master of the present utility model;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of sea cock and valve that is installed in tank bottom, comprise valve body 1, valve gap 3, flap 9, push rod 5, piston 18, piston rod 12, piston cylinder and pneumatic joint 24, valve body 1 is equipped with jump ring 2 with the cooperation place of valve gap 3, valve gap 3 is equipped with cover 4 in the top cover with the cooperation place of push rod 5, piston cylinder is formed by fixedly connecting by gas lid 15 and end cylinder 21, gas covers that 15 left ends are enclosed within on the piston rod 12 and in the cooperation place of gas lid 15 and piston rod 12 first Y-shaped ring and the 2nd O type circle is installed, cooperation place at gas lid 15 and valve body 1 is equipped with the 3rd O type circle, cooperation place at end cylinder 21 and piston 18 is equipped with second Y-shaped ring and the 4th O type circle, valve body 1 top has oilhole, and on oilhole, be coated with filter screen 7, flap 9 is fixedlyed connected by first self-locking nut 11 with push rod 5 and in the cooperation place of flap 9 and push rod 5 an O RunddichtringO 8 is installed and seals, in the cooperation place of flap 9 and valve body 1 sealing gasket 10 being installed seals, be set with Returnning spring 6 on the push rod 5, one end of Returnning spring 6 is against on the valve gap 3, the other end is against on the flap 9, piston rod 12 is fixedlyed connected by second self-locking nut 20 with the piston 18 in the piston cylinder, the front end of piston rod 12 props up push rod 5, pneumatic joint 24 is communicated with the piston cylinder inner chamber, valve body 1 is provided with emergency cut-off groove 25, and this emergency cut-off groove 25 is positioned on the outer wall on flange plate 1-1 right side of valve body 1.
As shown in Figure 1, the rear end of the end cylinder 21 of piston cylinder is connected with emergent bolt 23 and in the cooperation place of end cylinder 21 and emergent bolt 23 plain washer 22 is installed, and the front end of this emergent bolt 23 props up the rear end of piston rod 12.When opening valve under special circumstances, the emergent bolt 23 on the piston cylinder of bottom can be backed out, look for the hex head bolt tightening the screw mouth of a long 5cm of M12, slowly bolt is twisted inward then, till valve is opened.
Working principle of the present utility model is as follows:
When the tank car bottom is subjected to powerful collision, the emergency cut-off groove 25 of sea cock and valve will rupture automatically, make storage tank separate with car bottom pipeline, become the tank body of independent sealing, thereby prevent that pot liquid from leaking, and improve the Security of transportation greatly.
