Abstract

The utility model relates to improvements of structure of bonnet for diaphragm pump and in particular to a hydraulic bonnet for diaphragm pump which is convenient for dismounting. The utility model comprises a valve body which is provided with a gland and a bonnet, so disposed that the bonnet is fixed to the valve body by a stud, the upper part of the stud being an outer nut and an inner nut, the stud being connected to the bonnet through a plunger, a sealing gasket being arranged between the plunger and the bonnet, a gap between the bonnet and the plunger being connected to an input oil pipe which is lateral to the bonnet.

Description

A kind of diaphragm pump hydraulic type valve gap
Technical field
The utility model relates to a kind of improvement of diaphragm pump valve cover structure.
Background technique
Diaphragm pump feeding and discharging clack box is the charging and discharging one-way valve that is connected with chamber of septum.Clack box is made up of parts such as valve seat, valve rubber, valve cone, spring, fastening conduits, and fastening conduit is fixed on the valve gap.Each component in the clack box are easy to damage often by the slurry erosive wear in the clack box, need often to change.During replacing, must at first dismantle valve gap, this is a job of wasting time and energy, and needs the special tool dismounting usually.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of diaphragm pump hydraulic type valve gap of easy accessibility is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises valve body, valve body is provided with gland, valve gap, its structure outline is fixed in valve gap on the valve body by stud bolt, and the top of stud bolt is outer nut and inner nut, and stud bolt links to each other with valve gap by plunger, plunger is with being provided with sealing gasket between the valve gap, the gap of leaving between valve gap and the plunger links to each other with the input oil pipe of valve gap side.
The beneficial effects of the utility model: the utility model only is provided with several simple components such as stud bolt and plunger on the original structure basis, is easy to make, and is easy to popularize; In addition, utilize common hand pump just can dismantle valve gap easily, can control tightening torque accurately, and save special tool.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan view of Fig. 1.
In the accompanying drawing, 1 is valve body, and 2 is input oil pipe, and 3 is gland, and 4 is valve gap, and 5 is outer nut, and 6 is inner nut, and 7 is stud bolt, and 8 is plunger, and 9 is sealing gasket.
Embodiment
The utility model comprises valve body 1, valve body 1 is provided with gland 3, valve gap 4, by stud bolt 7 valve gap 4 is fixed on the valve body 1, the top of stud bolt 7 is outer nut 5 and inner nut 6, stud bolt 7 links to each other with valve gap 4 by plunger 8, plunger 8 is with being provided with sealing gasket 9 between the valve gap 4, the gap of leaving between valve gap 4 and the plunger 8 links to each other with the input oil pipe 2 of valve gap 4 sides.
For making good sealing effect, can between plunger 8 and valve gap 4, be provided with two sealing gaskets 9.
Specify valve gap using process of the present utility model below in conjunction with accompanying drawing: suppress in valve gap 4, with plunger 8 jack-up, deformation takes place in stud bolt 7 under the stretching action of inner nut 6; Stop when reaching required pretightening force suppressing and keep pressure in the valve gap 4, behind the locking outer nut 5, valve gap 4 internal pressures are unloaded.
Valve gap 4 unloading process: in valve gap 4, suppress, with plunger 8 jack-up, until the required pressure of dismounting.Outer nut 5 is unclamped, and the pressure in the unloading valve gap 4 is pushed inner nut 6 to take off aside again and is got final product.
