Description

Fast-assembling check valve

Technical Field

The utility model relates to a valve, in particular to fast-assembling check valve.

Background

The check valve is a valve that automatically opens and closes a valve flap depending on the flow of a medium itself to prevent the backflow of the medium, and is also called a check valve, a back-flow valve, and a back-pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium.

The existing check valve comprises a valve body, a sliding column arranged in the valve body in a sliding manner, a valve clack fixedly arranged on the sliding column and a driving spring for driving the valve clack to form a seal. Because the guiding and supporting function of the valve clack in motion mainly comes from the sliding fit position between the sliding column and the valve body, and the position is positioned at one side of the valve clack, when fluid has turbulence or turbulent flow in the flowing process, the valve clack is subjected to large lateral disordering force, so that the wear of the fit position between the sliding column and the valve body is easily caused, the valve clack in motion cannot be ensured to be accurately matched with the sealing surface of the valve body to form sealing, and the valve leakage is caused. And when the phenomenon of sudden cut-off of fluid in the valve occurs, the valve clack can impact the sealing surface of the valve under the action of the driving spring, so that the abrasion of the sealing surface is caused, and the service life of the valve is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fast-assembling check valve, this fast-assembling check valve can reduce the wearing and tearing of sealed face and traveller to this life who prolongs the valve promotes sealed effect, prevents to leak and takes place.

The above technical object of the present invention can be achieved by the following technical solutions: the utility model provides a fast-assembling check valve, includes the valve body, set up mounting bracket, the slip in the valve body and set up in the traveller of mounting bracket, along with the traveller motion and cooperate the valve body inner wall to constitute sealed valve clack and drive valve clack and constitute sealed actuating spring, the valve body inner wall is located the valve clack and is equipped with the mount pad for the position of mounting bracket opposite side, the mount pad is provided with a plurality ofly, every around encircleing the distribution in the valve clack centre of a circle all be equipped with the direction subassembly that is used for guiding the valve clack motion between mount pad and the valve clack, drive spring drive valve clack installs the bolster towards the motion of mount pad and in the direction subassembly.

Through adopting above-mentioned technical scheme, the setting of direction subassembly is used for guiding the direction of motion of spacing valve clack to through setting up the direction subassembly in the opposite side of valve clack for the mounting bracket, make when the valve clack receives fluidic side disorderly power, can form both ends atress to valve clack and traveller in the motion, better bearing and the atress on the balanced valve clack, make valve clack and traveller in the motion have higher structural strength, so that reduce the wearing and tearing that cause the traveller, thereby the life of extension valve. When the valve clack moves towards the sealing surface of the valve body under the action of the driving spring, the impact force of the valve clack is reduced by the buffer piece arranged to form sealing in cooperation with the sealing surface of the valve body, so that the service life of the sealing surface is prolonged, the sealing effect is improved, and leakage is prevented.

Further setting the following steps: each group the direction subassembly all includes along the valve clack motion and along the guide pole of traveller axis orientation mount pad extension and form in the mount pad and with guide rod sliding fit's bullport.

Through adopting above-mentioned technical scheme, the normal open and close motion of valve clack is guaranteed with bullport sliding fit to the guide pole, comes spacing valve clack's direction of motion through sliding fit's mode, bears the side direction random force that receives on the valve clack, promotes the structural strength of valve clack, avoids the traveller to cause excessive wearing and tearing.

Further setting the following steps: the position that the valve body inside wall corresponds to every mount pad all is equipped with the constant head tank that supplies the mount pad to inlay the dress, the mount pad install into the constant head tank and guide pole cooperation bullport limit the mount pad to break away from the constant head tank.

Through adopting above-mentioned technical scheme, the mode that the setting cooperation of constant head tank was inlayed and is realized the mount pad and lie in the fast-assembling in the valve body, makes the installation more simple and convenient, then comes spacing mount pad to be fixed in the constant head tank through cooperation between guide rod and the bullport between the two for the design of mount pad need not set up extra locking mechanical system, and the structure is simpler and make the direction subassembly have the dual function of guide and locking.

Further setting as follows: the buffer piece is a buffer spring which is sleeved on the guide rod and is positioned between the mounting seat and the valve clack.

By adopting the technical scheme, the valve clack moves towards the sealing surface of the valve body under the action of the driving spring, the moving valve clack is firstly contacted with the buffer spring, and the impact force of the valve clack is relieved so that the valve clack is matched with the sealing surface of the valve body to form sealing; the elastic force of the driving spring is greater than that of the buffer spring.

Further setting the following steps: the position that the valve body inside wall is located the mount pad below is equipped with the drainage piece that offsets bottom the mount pad, the inside wall of drainage piece is along the slide column axis from last to down towards the inclined plane of valve body inside wall one side slope gradually.

Through adopting above-mentioned technical scheme, the drainage piece cooperation inclined plane reduces the scouring that fluid medium caused to the mount pad, avoids the production of noise and vibration, prolongs the life of valve.

Further setting the following steps: the valve body includes valve body and lower valve body, go up through clamp connection between valve body and the lower valve body, go up the valve body and be equipped with the sealing washer down between the valve body, the sealing washer inner circle is equipped with the mounting groove, the mounting bracket install in the mounting groove.

Through adopting above-mentioned technical scheme, valve body, sealing washer and lower valve body are fixed to the clamp, and the setting of sealing washer guarantees to go up the leakproofness between valve body and the lower valve body, and fixed sealing washer has realized the fixed of mounting bracket through the mounting groove that sets up in the time to this realizes the fast-assembling of valve for the installation of valve is more simple and convenient.

Further setting the following steps: the mounting bracket all is equipped with sealed bulge loop corresponding to the both sides wall of mounting groove, the both sides wall of mounting groove all is equipped with the sealed annular that supplies its embedding corresponding to the position of sealed bulge loop.

Through adopting above-mentioned technical scheme, sealed bulge loop cooperation seal ring groove increases the sealed contact surface between the mounting bracket and the sealing washer between the two to further promote the sealing force between the two, reach better sealed effect with this.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses can reduce the wearing and tearing of sealed face and traveller to this life who prolongs the valve promotes sealed effect, prevents to leak and takes place.
