CN87203270U - Quick-change self-sealed valve - Google Patents

Abstract

The utility model discloses a quick-change self-sealed valve, which combines the output valve and the input valve, makes the actions of self sealing, opening the valve, and disengaging continuous, makes reasonable collocation, and ensures the rapid actions. The utility model has the advantages of high reliability, and no leakage; can be used for transfering the liquid from one container to another.

Description

Quick-change self-sealed valve

The utility model relates to a kind of valve, is applicable to from tank car and emits liquid, is put into the occasion of another container from a container.

The device of existing discharging or transmission medium adopts ball valve and sebific duct to cooperate and finishes.Its shortcoming is a troublesome poeration, and easily leaks solution, especially to oils and chemical industry solutions, leaks and also easily causes environmental pollution.

The purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, designs a kind ofly to connect soon---self-styledly---drives valve and closes the continuous valve of---self-styled---disconnecting process of valve.

Narration in conjunction with the accompanying drawings, content of the present utility model:

Quick change enclosed valve described in the utility model is made up of fixed end A and interchangeable end B, the left end of A links to each other with intake channel, right-hand member is fastening with screw and standing valve gate seat (9), (9) left end is screwed into spring levelling seat (13), spring (1) is housed on its boss, there is screw thread levelling seat (13) outside, therefore it is screwed into or back-outs and can adjust the sealing load of dress left valve (2) thereon to standing valve gate seat (9), having on the right flange of standing valve gate seat (9) at a distance of 120 ° 3 and axially push groove (4), is the inclined-plane (12) that compresses usefulness in 30 ° of scopes of groove back.

The right-hand member of interchangeable end B links to each other with outlet pipe, its left end is equipped with three rollers (3) at a distance of 120 °, its left end endoporus is equipped with interchangeable valve base (10) and fixes with pin and B, its right-hand member is equipped with interchangeable valve body (11), cam path cover (7) is housed (11), and it is (11) and (7) are fixing with pin, (7) outside has 2 cotter ways (14) of symmetry, preceding 30 ° is straight trough, the back is a skewed slot for 30 °, 2 pins (6) on the B end rotate in this groove, and the left end of (11) is equipped with right valve (8) and spacer (15).

Work as A, when the B end separates, (2) because being in sealing separately, the effect of spring (1) and cotter way (14) closes state with (10) with (9) and (8), work as A, when B end desire engages, holding 2 handles (5) holds roller (3) to push in the A end slot (4) to 30 ° of right rotations B, this moment, two ends compressed and self-styled in C face (the rubber skin is housed on it), when continuing to rotate 30 °, pin (6) enters cotter way (14) skewed slot part, thereby force piece number (7), (11), (8), (2) move to left and 2 valves (2) and (8) are kept self-styled, when continuing 30 ° of counter-rotatings again, the C face unclamps, roller this moment (3) is in alignment slot (4) position, can extract A immediately, throw off at the B two ends, and whole process has reached and connect soon-self-styled-Kai valve and the overall process of closing valve-self-styled-disengagement.

Compared with prior art, the utility model has the advantage of: A, B two parts connect, Throw off continuously, fast, rationally, gapless between valve (2) and (8), dielectric leakage can not take place. Reliable in action is rapidly easy to use.

Claims (2)

1, a kind of quick change enclosed valve.Be made up of fixed end A and interchangeable end B, it is characterized in that A is a garden shape flange plate, its left end endoporus has screw thread to be screwed on the intake channel, and right output port is fastening with screw and standing valve gate seat (9).(9) profile is cylindrical, and its left end endoporus is a tapped hole, and spring levelling seat (13) is screwed in the screw, and (13) have boss.Its endoporus circular left valve (2) of packing into, cylindrical helical spring on the boss outer cover (1), the back-outing or be screwed into of (13).Can adjust to have on the right flange of left valve (2) to the sealing load standing valve gate seat (9) of standing valve gate seat (9) at a distance of 120 ° three and push groove (4), 30 ° of inclined-planes of groove back are to compress inclined-plane (12)

The right-hand member of interchangeable end B is equipped with interchangeable valve body (11), and its endoporus is that tapped hole links to each other with the rubber hose coupling that flows out sebific duct, and its left end is equipped with three rollers (3) and the interchangeable valve base (10) at a distance of 120 °, and cam path cover (7) is housed on (11).It is shaped as cylindrical, and with pin (11) and (7) is fixed together, and there are 2 cotter ways (14) of symmetry the outside of (7), preceding 30 ° is straight trough, the back is a skewed slot for 30 °, and 2 pins (6) on the B end rotate in groove, and the left end of (11) is equipped with right valve (8) and spacer (15).

2, according to the quick change enclosed valve of claim 1, the gradient that it is characterized in that described left and right sides valve (2) and (8) in the same way.
