The technical characteristics are that the device comprises an elastic sleeve and a pressing mechanism arranged on the elastic sleeve; a taper sleeve is sleeved outside the elastic sleeve, a gasket is sleeved at the lower end of the elastic sleeve and positioned on the lower surface of the taper sleeve, and an inner hexagonal socket head cap screw is fixedly arranged on the lower surface of the elastic sleeve; the pressing mechanism is used for being inserted into the elastic sleeve to be pressed. The device is simple to operate, low in manufacturing cost, small in contact stress area and free of damage to the surface of the valve seat caused by excessive clamping.

Description

Base valve seat cover fixing base

Technical Field

The utility model relates to a bottom valve is fixed technical field, in particular to bottom valve seat lid fixing base.

Background

The bottom valve is an energy-saving valve, is generally arranged at the bottom end of an underwater suction pipe of a water pump, limits liquid in the water pump pipe to return to a water source, and has the function of only entering and not exiting.

However, the existing base valve seat cover is poor in fixing effect, and parts are easily damaged in the using process, so that the equipment processing progress is influenced, and therefore, the base valve seat cover fixing seat is necessary to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is not good to solve the fixed effect of bottom valve seat lid among the prior art, and the in-process of use damages part technical problem easily, provides a bottom valve seat lid fixing base.

In order to solve the technical problem, the technical scheme of the utility model is specifically as follows:

a base valve seat cover fixing seat comprises an elastic sleeve and a pressing mechanism arranged on the elastic sleeve;

a taper sleeve is sleeved outside the elastic sleeve, a gasket is sleeved at the lower end of the elastic sleeve and positioned on the lower surface of the taper sleeve, and an inner hexagonal socket head cap screw is fixedly arranged on the lower surface of the elastic sleeve;

the pressing mechanism is used for being inserted into the elastic sleeve to be pressed.

Preferably, the elastic sleeve is made of MN material.

Preferably, the pressing mechanism comprises a valve seat, a valve cap and a bottom valve;

the center of the upper surface of the bottom valve assembly is provided with a mounting hole;

the valve cap is sleeved at the upper end of the valve seat and is embedded in the mounting hole;

the lower end of the valve seat is inserted into the elastic sleeve.

The utility model discloses following beneficial effect has:

the device is simple to operate, low in manufacturing cost, small in contact stress area and free of damage to the surface of the valve seat caused by excessive clamping.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural view of a base valve seat cover fixing seat of the present invention;

fig. 2 is a schematic view of a tightening state of the base valve seat cover fixing seat of the present invention.

The reference numerals in the figures denote:

1. an elastic sleeve; 2. a taper sleeve; 3. a gasket; 4. a socket head cap screw; 5. a valve seat; 6. a bonnet; 7. a bottom valve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a base valve seat cover fixing seat includes an elastic sleeve 1, and a pressing mechanism disposed on the elastic sleeve 1;

a taper sleeve 2 is sleeved outside the elastic sleeve 1, a gasket 3 is sleeved at the lower end of the elastic sleeve 1 and positioned on the lower surface of the taper sleeve 2, and an inner hexagonal socket head cap screw 4 is fixedly arranged on the lower surface of the elastic sleeve 1;

the compressing mechanism is used for being inserted into the elastic sleeve 1 to compress.

The elastic sleeve 1 is made of 60MN material.

The pressing mechanism comprises a valve seat 5, a valve cap 6 and a bottom valve assembly 7;

a mounting hole is formed in the center of the upper surface of the bottom valve assembly 7;

the valve cap 6 is sleeved at the upper end of the valve seat 5, and the valve cap 6 is embedded in the mounting hole;

the lower end of the valve seat 5 is inserted into the elastic sleeve 1.

The working principle is as follows:

the valve cap 6 is difficult to screw into or unscrew from the valve seat 5, and the contact stress area of the valve seat 5 is small, so that the surface of the valve seat 5 cannot be damaged due to over-clamping.

The elastic sleeve 1 is sleeved into the taper sleeve 2, the straight section cylindrical surface of the valve seat 5 is tightly held by the elastic connecting sleeve, the elastic sleeve 1 is screwed into the taper sleeve 2 downwards by screwing the hexagon socket head cap screw 4, and the conical surface of the elastic sleeve 1 is stressed to clamp the valve seat 5 tightly.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
