Abstract
The utility model discloses a pump and valve-integrated combined system, which comprises a pump body, wherein the pump body is provided with a lifting valve; an oil return channel of the lifting valve is connected with the oil inlet and return port of the pump body; an oil inlet channel of the lifting valve is connected with a pump oil outlet pipe of the pump body through a high-pressure connecting pipe; an oil outlet channel of the lifting valve is connected to an oil cylinder through an oil outlet pipe; and the oil inlet and return port of the pump body is connected to an oil tank through a low-pressure pipe. The pump and valve-integrated combined system has the beneficial effects: the pump body works when an integrated pump-valve arranged on an automobile runs, and the inside of a hydraulic oil pipe and the oil outlet pipe and the lifting valve are free from liquid flow pressure when the oil cylinder is not required to be lifted, so that hydraulic oil consumption can be lowered, idling pressure of the pump body is lowered, and the service life of relevant components such as the pump body, the oil pipe, the lifting valve and the like is prolonged. A connecting oil channel port between the pump body and the lifting valve is provided with a filtering system, so that impurities in oil are filtered out in advance, the valve and the oil cylinder are protected, and the phenomena of valve sticking and oil cylinder scoring are avoided.
Description
Technical field
The utility model relates to a kind of pump valve, more specifically says, it relates to a kind of group shot of pump valve one.
Background technique
Existing car hydraulics does not match, and it is stuck that lifting valve advances impurity easily, and oil cylinder forms scuffing of cylinder bore easily, and the automobile assembling is consuming time; Vehicle body is overweight, and the cost of raw material is high, and hydraulic power consumption is big; The complicated disunity of oil-way system, pump originally, valve separation system, a start hydraulic pressure whole system is worked stressed simultaneously; Open the pressure that the resistance of valve, pipe, joint causes by act, pump power taking and system are caused load, seriously shortened the working life of gear pump.
Summary of the invention
The purpose of the utility model is to overcome deficiency of the prior art, and a kind of pump valve coupling is provided, life-saving, and convenient the installation saved the group shot of the pump valve one of material.
The purpose of the utility model realizes through following technological scheme: the group shot of this pump valve one; Comprise the pump housing; The said pump housing is provided with lifting valve, and the back oil road of said lifting valve connects the oil inlet and oil return mouth of the pump housing, and the oil input channel of said lifting valve connects the oil pump outlet line of the pump housing through the high pressure connecting tube; The oil road of lifting valve is connected to oil cylinder through oil outlet tube, and the oil inlet and oil return mouth of the said pump housing is connected to fuel tank through low-voltage tube.
As preferably: the said pump housing is provided with relief valve.
As preferably: the oil pump outlet line of the said pump housing is provided with one-way valve.
As preferably: said lifting valve is provided with the gas control road that is used to control and is connected with portable valve through tracheae.
As preferably: the oil road of said lifting valve is provided with filter screen.
The beneficial effect of the utility model is: when group shot when operation that automobile is installed the pump valve one of the utility model, the pump housing is in work, but when oil cylinder does not need lifting; Interior and the oil outlet tube of hydraulic oil pipe, lifting valve does not have flow stream pressure; Can reduce hydraulic oil consumption like this, reduce the pressure of pump housing idle running, improve the pump housing; Oil pipe, the life-span of associated components such as lifting valve.Be connected the oil circuit mouth with lifting valve at the pump housing filtration system is set, the impurity in the oil is filtered out in advance, Protective valve and oil cylinder are avoided the stuck phenomenon and the oil cylinder pull-cylinder phenomena of valve.Originally all component installation processes of car hydraulics are all accomplished on vehicle chassis; Inconvenient installation is consuming time, and all component of group shot of the pump valve one of the utility model can install earlier and be one, is installed on the vehicle body again; Convenient and swift technical difficulty is low, is convenient to systems management.Can save 3.5 meters hydraulic oil pipes, reduce flow power simultaneously and run off, the lifting power of oil hydraulic cylinder is more sufficient, improves the sealing of whole oil circuit.Weight is 13.7kg, than about traditional gear pump and the light 40kg of valve, has alleviated tare greatly, well improves the usability of car.During work, the fluid oil return is to get back to fuel tank bottom from oil pipe, is oil return from the bottom up, so pump housing oil suction can be in impurity and the sludge suction pump housing, so oil-feed has all been carried out effective protection without filter screen to hydraulic system.

Description of reference numerals: the pump housing 1, lifting valve 2, fuel tank 3, oil cylinder 4, low-voltage tube 5, oil outlet tube 6, one-way valve 7, high pressure connecting tube 8, filter screen 9, gas control road 10, oil input channel 11, oil road 12, back oil road 13, oil inlet and oil return mouth 14, relief valve 15, oil pump outlet line 16, portable valve 17.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described.Though the utility model will combine preferred embodiment to describe, and should know, do not represent that the utility model is limited among the said embodiment.On the contrary, the utility model will be contained interior alternative, modified model and the equivalent of scope of the utility model that can be included in attached claims qualification.
Extremely shown in Figure 7 like Fig. 1; The group shot of this pump valve one comprises the pump housing 1, and the said pump housing 1 is provided with lifting valve 2; Said lifting valve 2 is provided with the gas control road 10 that is used to control and is connected with portable valve 17 through tracheae. and the back oil road 13 of said lifting valve 2 connects the oil inlet and oil return mouth 14 of the pump housing 1; The oil input channel 11 of said lifting valve 2 is through the oil pump outlet line 16 of the high pressure connecting tube 8 connection pump housings, and said oil pump outlet line 16 is provided with one-way valve 7, and direction is from oil pump outlet line 16 to oil input channel 11; The oil road 12 of lifting valve 2 is provided with filter screen 9 and is connected to oil cylinder 4 through oil outlet tube 6, and the oil inlet and oil return mouth 14 of the said pump housing 1 is connected to fuel tank 3 through low-voltage tube 5.The said pump housing 1 is provided with relief valve 15.
During operation; When needs elevating ram 4, then lifting valve 2 is opened, and the fluid in the fuel tank 3 gets into the oil inlet and oil return mouth 14 of the pump housing 1 through low-voltage tube 5; Then through after the pressurization of the pump housing 1; Fluid exports the oil input channel 11 of lifting valve 2 to and through the filtration of filter screen 9, is exporting oil cylinder 4 from oil road 12 through oil outlet tube 6 through the lifting valve of opening 2 from oil pump outlet line 16 output and through high pressure connecting tube 8, realizes the lifting of oil cylinder 4.When the needs oil return, the fluid in the oil cylinder 4 gets into the oil inlet and oil return mouth 14 of the pump housings 1 again through the oil road 12 of oil outlet tube 6 entering lifting valves 2 through back oil road 13, return to fuel tank 3 through low-voltage tube 5 again.When not needing elevating ram 4, lifting valve 2 is closed, and oil outlet tube 6, lifting valve 2 etc. do not have flow stream pressure at this moment, reduces fluid consumption, reduces the pressure of the pump housing 1 idle running, improves the life-span of associated components such as the pump housing 1, oil pipe, valve.
